Executive Summary

Introduction

SRK Consulting (Canada) Inc. (SRK) has been retained by Southern Arc Minerals Inc. (Southern Arc

or the company) to prepare a technical report summarizing the mineral resources for the West

Lombok Project. The mineral resource estimate is to form the first time disclosure of mineral

resources by Southern Arc for the West Lombok Property.

SRK‟s scope of work for the West Lombok Property included the construction of mineral resource

models for the Raja, Bising and Tibu Serai epithermal gold mineralisation, and the Selodong

porphyry copper gold mineralisation and the preparation of an independent technical report in

compliance with National Instrument 43-101 and Form 43-101F1 guidelines.

The mineral resource statement reported herein is a collaborative effort between Southern Arc and

SRK personnel. The exploration database was compiled and maintained by Southern Arc, and was

audited by SRK. The geological model and outlines for the gold mineralisation were constructed by

SRK from a two-dimensional geological interpretation provided by Southern Arc. In the opinion of

SRK, the geological model is a reasonable representation of the distribution of the targeted

mineralisation at the current level of sampling. The mineral resource statement reported herein was

presented to Southern Arc in a memorandum report on July 11, 2013. In accordance with National

Instrument 43-101 guidelines, Dr. Arseneau visited the West Lombok Property on December 6

through 9, 2011 and on April 23 to 26, 2013 accompanied by Andrew Rowe Executive Vice

President and Chief Geologist of Southern Arc.

Property Description and Ownership

The West Lombok Property hosts an early stage gold and copper exploration project located in

Indonesia. It is located on the southwest corner of the Island of Lombok and covers a northwest

trending mineralized corridor that extends for approximately 13 by 7 kilometres. Southern Arc

Minerals Inc., through Indotan Lombok Pte. Ltd., holds a 90% interest in PT. Indotan Lombok Barat

Bangkit (“PT ILBB”), an Indonesian approved foreign investment company (Penanaman Modal Asing

or PMA Company that holds a 100% interest in the West Lombok Property. The remaining 10%

interest of PT ILBB is held by the West Lombok Regency Government as a free-carry loan

arrangement.

Geology and Mineralisation

The geology of the West Lombok Property is characterized by an island-arc volcano-sedimentary

succession of Late-Oligocene to Quaternary age. The southern parts of Lombok Island are overlain

by Late Oligocene to Middle Miocene, low potassium calc-alkaline to weakly alkaline andesitic

volcanic and interbedded volcaniclastic rocks, associated low potassium intermediate intrusions and

shallow marine sedimentary rocks and limestone.

The West Lombok Property covers a northwest trending structural corridor of mineralisation and

alteration hosting three main prospects: the Pelangan epithermal gold prospect, the Mencanggah

epithermal/porphyry district, and the Selodong porphyry intrusive complex. The Raja resource area

is situated within the Pelangan Prospect, the Bising and Tibu Serai resource areas are within the

2CS032.000 – Southern Arc Minerals Inc. Independent Technical Report for the West Lombok Gold and Copper Project, Lombok, Indonesia Page iv


Mencanggah Prospect and the Selodong porphyry copper-gold deposit is within the Selodong

Prospect area.

Exploration Status

A total of 210 BLEG, 210 stream sediments, 6 rock chips and 14 rock float samples were collected in

the Pelangan-Mencanggah area. Geological mapping traverses were conducted using tape and

compass surveys over a 35 square kilometre area.

Drilling has been carried out on the Mencanggah Prospect area by Southern Arc and on the

Selodong and Pelangan Prospect areas by Newmont and Southern Arc. Drilling by Southern Arc

was carried out using up to ten drill rigs. A total of 47,750 m have been drilled in 253 holes on the

property.

SRK is of the opinion that the drilling programs carried out by Southern Arc on the West Lombok

property are sufficient and adequately spaced for use in the estimation of mineral resources for the

Pelangan, Mencanggah and Selodong prospect areas.

Mineral Resource Estimates

The mineral resource model prepared by SRK considers 253 of the core boreholes drilled by

Southern Arc and previous owners of the property during the period of 2005 to 2013. Of these, 99

drill holes intersected the mineralised zones and are included in the resource estimate: 36 drill holes

totalling 5,787 m were included in the Raja resource model, 22 drill holes totalling 3,830 m were

included in the Bising model, 10 holes totalling 1,370 m were included in the Tibu Serai model and

31 holes totalling 11,012 m were included in the Selodong model. The resource estimation work was

completed by Dr. Gilles Arseneau, P.Geo. (APEGBC #23474) an appropriate “independent qualified

person” as this term is defined in National Instrument 43-101. The effective date of the resource

statement is June 29, 2013.

Mineral resources were estimated for four separate deposits by Ordinary Kriging using Gemcom

block modelling software in three separate models. The Raja, Bising and Tibu Serai block model

used 10 x 10 x 5 m blocks and the Selodong model used a 10 x 10 x 10 m block. Grade estimates

were based on capped, 1 m composited assay data for Raja, 1.5 m composited data for Bising and

Tibu Serai and 3 m composites for the Selodong. Gold capping levels were set at 30 g/t for the Raja

model, 5 g/t for the Bising and Tibu Serai models and 4 g/t for the Selodong model. All blocks in all

models were classified as inferred mineral resources. Mineral resources for Bising and Tibu Serai

were estimated in the same block model.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The

estimate of mineral resources may be materially affected by environmental, permitting, legal, title,

taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported

inferred resources in this estimation are uncertain in nature. There has been insufficient exploration

to define these inferred resources as an indicated or measured mineral resource. It is uncertain if

further exploration will result in upgrading them to an indicated or measured mineral resource

category.

The mineral resources were estimated using current Canadian Institute of Mining, Metallurgy and

Petroleum (CIM) standards, definitions and guidelines. SRK considers that major portions of the

2CS032.000 – Southern Arc Minerals Inc. Independent Technical Report for the West Lombok Gold and Copper Project, Lombok, Indonesia Page v


mineralisation at the West Lombok Property may be amenable for open pit extraction. In order to

determine the quantities of material offering “reasonable prospects for economic extraction” by an

open pit, SRK used a pit optimizer and reasonable mining assumptions to evaluate the proportions

of the block model that could be “reasonably expected” to be mined from an open pit. The mineral

resources for the West Lombok Property are summarised in Table i below:

* Reported at a cut-off grade of 0.5 g/t gold equivalent inside a Whittle pit shell for Raja, a 0.5 g/t Au cut-off for Bising and Tibu Serai and a 0.25 copper equivalent for Selodong. Gold equivalent is calculated using US$1500 per ounce of gold and US$25 per ounce of silver and 100% metal recoveries are assumed for both metals. Copper equivalent is calculated using US$1500 per ounce of gold and US$3.56 per pound of copper and 100% metal recoveries are assumed for both metals. Mineral resources are not mineral reserves and do not have demonstrated economic viability. All numbers have been rounded to reflect the relative accuracy of the estimates. Gold was capped at 30 g/t for Raja, 5 g/t for Bising and Tibu Serai and 4 g/t for Selodong. No capping was applied to copper.

Conclusion and Recommendations

The West Lombok Property hosts at least four separate mineral deposits within a 10 km strike

length. Both epithermal gold and porphyry copper-gold deposits have been identified and a large

portion of the property still remains to be explored in detail. All deposits identified so far are still open

along strike and at depth and additional drilling could discover additional mineralisation, especially at

Raja where the possibility of finding mineralisation that could be amenable to underground mining

seems very good.

The West Lombok Property contains several other mineral occurrences and only a small portion of

the favourable ground has been drill tested to date. SRK is of the opinion that the untested mineral

occurrences represent a great opportunity to locate additional mineralisation on the West Lombok

Property.

SRK recommends that Southern Arc continue to explore the West Lombok Property. Specifically,

SRK recommends:

At Raja, further 2,625 m of drilling is required to upgrade the resource status and to extend resources down-plunge of open high-grade shoots;

A further 1,385 m of drilling is required on Bising to infill the upper high-grade parts of the structure and test open extensions along strike and down dip;

At Tibu Serai, where the current resource zone is only drilled on a 250 m long zone of MSB, further drilling is required to test open extensions down dip and along strike;

Metallurgical sampling and testing at Raja and Bising Deposits;

2CS032.000 – Southern Arc Minerals Inc. Independent Technical Report for the West Lombok Gold and Copper Project, Lombok, Indonesia Page vi


Scout drilling to test the Lala structure located some 350 m east of, and parallel to the Raja deposit. Here numerous high-grade rock chip samples have been collected along an 800 metre strike zone;

Scout drilling is warranted at several other targets with high-grade rock chip sampling at Mencanggah, including the 2-km long Mahoni zone;

Selective ground IP geophysics is recommended to focus porphyry drill testing on the higher priority porphyry targets;

SRK estimates that the first exploration phase at Raja will cost approximately $766,000.Contingent

on positive results from the first phase of drilling, SRK recommends an additional $421,000 in

exploration expenditures and an additional $800,000 of scout drilling for a total exploration

commitment of approximately $2 million.

2CS032.000 – Southern Arc Minerals Inc. Independent Technical Report for the West Lombok Gold and Copper Project, Lombok, Indonesia Page 13


1 Introduction and Terms of Reference The West Lombok Property hosts an early stage gold and copper exploration project located in

Indonesia. It is located on the west side of the Island of Lombok and covers a mineralised corridor

that extends for approximately 13 kilometres (km) by 7 km. Southern Arc Minerals Inc. (Southern Arc

or the Company) through its wholly owned Singapore subsidiary Indotan Lombok Pte. Ltd. holds a

90% interest in PT. Indotan Lombok Barat Bangkit, an Indonesian approved foreign investment

company (Penanaman Modal Asing or PMA company) that holds a 100% interest in the West

Lombok Property. The remaining 10% interest is held by the West Lombok Regency Government as

a free-carry loan arrangement.

In November 2011 and in April 2013, Southern Arc commissioned SRK Consulting (Canada) Inc.

(SRK) to visit the property and prepare a geological and mineral resource model for the West

Lombok Project. The services rendered between April 2013 and June 2013 lead to the preparation of

the mineral resource statement reported herein that was disclosed publically by Southern Arc in a

news release on July 11, 2013.

This technical report documents a mineral resource statement for the West Lombok Project prepared

by SRK. It was prepared following the guidelines of the Canadian Securities Administrators‟ National

Instrument 43-101 and Form 43-101F1. The mineral resource statement reported herein was

prepared in conformity with generally accepted CIM “Estimation of Mineral Resources and Mineral

Reserves Best Practice Guidelines.”

This technical report summarises the technical information available on the West Lombok Property

and demonstrates that the West Lombok Project clearly merits additional exploration expenditures.

An exploration work program is recommended comprising diamond core drilling and geological and

mineral resource modelling to better define the identified mineral resource and to upgrade the

resource classification.

1.1 Scope of Work

The scope of work, as defined in a letter of engagement executed in November 2011 between

Southern Arc and SRK, includes the construction of a mineral resource model for the Raja, Bising

and Tibu Serai epithermal gold mineralisation and the Selodong porphyry copper gold mineralisation

and the preparation of an independent technical report in compliance with National Instrument 43-

101 and Form 43-101F1 guidelines. This work typically involves the assessment of the following

aspects of this project:

Topography, landscape, access;

Regional and local geology;

Exploration history;

Audit of exploration work carried out on the project;

Geological modelling;

Mineral resource estimation and validation;

Preparation of a mineral resource statement; and

Recommendations for additional work.



1.2 Work Program

The mineral resource statement reported herein is a collaborative effort between Southern Arc and

SRK personnel. The exploration database was compiled and maintained by Southern Arc, and was

audited by SRK. The geological model and outlines for the gold mineralisation were constructed by

SRK from a two-dimensional geological interpretation provided by Southern Arc. In the opinion of

SRK, the geological model is a reasonable representation of the distribution of the targeted

mineralisation at the current level of sampling. The geostatistical analysis, variography and grade

models were completed by SRK during the months of April and June, 2013. The mineral resource

statement reported herein was presented to Southern Arc in a memorandum report on July 11, 2013

and disclosed publicly in a news release dated July 11, 2013.

The mineral resource statement reported herein was prepared in conformity with generally accepted

CIM “Exploration Best Practices” and “Estimation of Mineral Resource and Mineral Reserves Best

Practices” guidelines. This technical report was prepared following the guidelines of the Canadian

Securities Administrators‟ National Instrument 43-101 and Form 43-101F1.

The technical report was assembled in SRK‟s Vancouver office during the months of May and July,

2013.

1.3 Basis of Technical Report

This report is based on information collected by SRK during site visits performed between December

6 to 9, 2011 and April 23 to 26, 2013 and on additional information provided by Southern Arc

throughout the course of SRK‟s investigations. Other information was obtained from the public

domain. SRK has no reason to doubt the reliability of the information provided by Southern Arc. This

technical report is based on the following sources of information:

Discussions with Southern Arc personnel;

Inspection of the West Lombok Project area, including outcrop and drill core;

Review of exploration data collected by Southern Arc; and

Additional information from public domain sources.

1.4 Qualifications of SRK and SRK Team

The SRK Group comprises over 1,650 professionals, offering expertise in a wide range of resource

engineering disciplines. The SRK Group‟s independence is ensured by the fact that it holds no equity

in any project and that its ownership rests solely with its staff. This fact permits SRK to provide its

clients with conflict-free and objective recommendations on crucial judgment issues. SRK has a

demonstrated track record in undertaking independent assessments of Mineral Resources and

Mineral Reserves, project evaluations and audits, technical reports and independent feasibility

evaluations to bankable standards on behalf of exploration and mining companies and financial

institutions worldwide. The SRK Group has also worked with a large number of major international

mining companies and their projects, providing mining industry consultancy service inputs.

The resource evaluation work and the compilation of this technical report were completed by Dr.

Gilles Arseneau, P. Geo (APEGBC). By virtue of his education, membership to a recognized



professional association and relevant work experience, Dr. Arseneau is an independent Qualified

Person as this term is defined by National Instrument 43-101.

Marek Nowak, P. Eng. (APEGBC), a Principal Geostatistician with SRK, reviewed drafts of this

technical report prior to their delivery to Southern Arc as per SRK internal quality management

procedures. Mr. Nowak did not visit the project.

1.5 Site Visit

In accordance with National Instrument 43-101 guidelines, Dr. Arseneau visited the West Lombok

project on December 6 through 9, 2011 and on April 23 to 26, 2013 accompanied by Andrew Rowe,

Executive Vice President and Chief Geologist of Southern Arc.

The purpose of the site visit was to review the digitalization of the exploration database and

validation procedures, review exploration procedures, define geological modelling procedures,

examine drill core, interview project personnel, and to collect all relevant information for the

preparation of a mineral resource model and the compilation of a technical report. During the visit,

particular attention was given to the treatment and validation of drilling data.

The site visit was also aimed at investigating the geological and structural controls on the distribution

of the gold mineralisation in order to aid the construction of three dimensional gold mineralisation

domains.

SRK was given full access to relevant data and conducted interviews of Southern Arc personnel to

obtain information on the past exploration work, and to understand procedures used to collect,

record, store and analyze historical and current exploration data.

1.6 Acknowledgement

SRK would like to acknowledge the support and collaboration provided by Southern Arc personnel

for this assignment. Their collaboration was greatly appreciated and instrumental to the success of

this project.

1.7 Declaration

SRK‟s opinion contained herein and effective July 11, 2013, is based on information collected by

SRK throughout the course of SRK‟s investigations, which in turn reflect various technical and

economic conditions at the time of writing. Given the nature of the mining business, these conditions

can change significantly over relatively short periods of time. Consequently, actual results may be

significantly more or less favourable.

This report may include technical information that requires subsequent calculations to derive sub-

totals, totals and weighted averages. Such calculations inherently involve a degree of rounding and

consequently introduce a margin of error. Where these occur, SRK does not consider them to be

material.

SRK is not an insider, associate or an affiliate of Southern Arc, and neither SRK nor any affiliate has

acted as advisor to Southern Arc, its subsidiaries or its affiliates in connection with this project. The

results of the technical review by SRK are not dependent on any prior agreements concerning the



conclusions to be reached, nor are there any undisclosed understandings concerning any future

business dealings.

3 Property Description and Location The West Lombok Property covers a northwest trending structural corridor of mineralisation and

alteration hosting three main prospects: the Pelangan epithermal gold prospect, the Mencanggah

epithermal/porphyry district, and the Selodong porphyry intrusive complex. The Raja resource area

is situated within the Pelangan prospect, the Bising and Tibu Serai resource areas are within the

Mencanggah prospect and the Selodong porphyry copper-gold deposit is within the Selodong

prospect area (Figure 3.1). Exploration of the West Lombok Property is controlled under an Izin

Usaha Pertambangan (IUP) Mining Business Licence encompassing 10,088 hectares (ha). The

property boundaries were located using a differential global positional system (DGPS) instrument

along with locations of all known mineralised outcrops, historical workings such as drill collars, drill

pads, trenches and access in order to tie them into the WGS 84 co-ordinate system used by

Southern Arc.

(Source Southern Arc, 2010)

Figure 3.1: Property location map



The property is centered at 116°00‟04” longitude and -8°48‟25” latitude, approximately 6 km

southwest of Sekotong or 30 km southwest (straight map distance) of Mataram City in Lombok, the

capital of West Nusa Tengara Province, Indonesia (Figure 3.2).


Figure 3.2: Property access and claim boundaries

3.1 Mineral Tenure

The property was initially explored under a Contract of Work application (CoW) that was granted in-

principle approval on July 21, 1998 by the Central Department of Mines and Energy. In 2011, the

CoW was converted to an IUP that encompasses 10,088 ha. The IUP, issued in January 2011, is

valid for five years. The IUP permits the company to pursue exploration activities up to the

conclusion of a feasibility study. This period may be extended with approval of the Indonesian

Government. On approval of a feasibility study, the company can automatically transition the IUP

into the exploitation stage, with the right to conduct mining production on this property for 20 years

with the potential for two further 10-year extension periods. In addition to the IUP, the Ministry of

Forestry Pinjam Pakai permit required for exploration activities within areas designated as production

forest was issued in November 2012. On the West Lombok property, 1.1% of the area is designated

protected forest (no open-pit mining), 55.1% is designated production forest (open-pit mining

allowed) and 43.8% has no forestry designation (no restriction on mining activities).



3.2 Underlying Agreements

Southern Arc acquired its original interest in the West Lombok property in 2005 by paying $57,100

and issuing 8,050,000 common shares to Sunda Mining Corporation (Sunda) and by paying

$126,000 and issuing 700,000 common shares to Indotan Inc. (Indotan). The Company also granted

two 0.5% net smelting royalties (NSR) to two individuals related to Sunda and a 1% NSR to Indotan

Inc. on approximately 8% of the current West Lombok Property, which excludes Block 1 described in

Figure 3.3.

This area was previously held by PT Newmont Nusa Tenggara (Newmont or PT NNT), a subsidiary

of Newmont Mining Corporation. In August 2005, Southern Arc entered into an agreement with

Newmont regarding a property (Block 1) that now forms the western portion of the West Lombok

Property and is included in the West Lombok IUP (Figure 3.3). The acquisition was completed

through a relinquishment by Newmont of the Block 1 area. The terms of the agreement include

granting Newmont a 2% NSR on any mineral production from the Block 1 area and a right of first

refusal should the company wish to introduce a new partner into any development within the area

originally covered by Block 1. The company has the right to repurchase this 2% NSR at any time for

US$1 million.

Southern Arc has given a free-carry interest for 10% of the West Lombok Project to the local

Regency Government as per a cooperation agreement signed in December 2010, ensuring

government support for the project and long-term benefits for local communities as the project

advances. Southern Arc believes that having the local Regency Government as an equity partner

creates a synergistic and mutually beneficial environment for advancement of the project. This

relationship ensures it is in the local government‟s interest to support the company‟s activities and

that local communities will receive benefits directly from Southern Arc‟s success at the project. The

Regency interest is loan-carried through to a production scenario, whereby debt and equity

contribution are paid back through dividends or other financial means.

3.3 Permits and Authorization

In order to carry out exploration and reported drilling programs Southern Arc has satisfied all

government permitting requirements which include;

IUP, (mining and exploration permit) granted for 5 years on the 5 January 2011.

Clear and Clean Certificate, indicating no overlapping claims and that all IUP associated

permitting and statutory responsibilities are in order.

UKL-UPL approval by the regency environmental department of the forward exploration plan.

Pinjam-Pakai or borrow / use permit required for work to be carried out in forest designated areas

granted on the 31st October 2012.

3.4 Environmental Considerations

Since receiving its West Lombok IUP in January 2011, Southern Arc has proactively engaged with

local communities to discuss its exploration and development plans and to address questions and

concerns. The company offers employment and training programs and undertakes an extensive

CSR program through its fully-funded foundation, with an emphasis on education, community health,



environmental protection and economic empowerment of local communities. In 2012, Southern Arc

granted six micro-credit loans to local village members to support entrepreneurial initiatives.

In 2009 Southern Arc requested the University of Mataram in consultation with the biology faculty of

the University Gadjah Madah to produce a baseline study of mercury contamination caused by

artisanal gold mining and processing within the IUP. The study was completed in 2009 and

documented mercury contamination in gold processing areas and background levels in

uncontaminated areas. The findings of this report were made public and presented to the Regency

government in 2010.

3.5 Mining Rights in Indonesia

The following is taken with modifications from Norton Rose Fulbright website:

http://www.nortonrosefulbright.com/knowledge/publications/64444/new-indonesian-mining-

regulations .

On 21 February 2012, the Indonesian Government issued Regulation No. 24 of 2012 on Amendment

to Government Regulation No. 23 of 2010 on Mineral and Coal Mining Business Activities

(Regulation No. 24). Regulation No. 24 increases the divestment requirement to Indonesian interests

for Foreign Investment Companies (PMA Companies) holding an IUP, from 20% to 51%. The new

divestment requirement commences after five years of commercial production, and is as follows:

20% in the sixth year;

30% in the seventh year;

37% in the eighth year;

44% in the ninth year; and

51% in the 10th year

Regulation No.7/2012 issued by the Ministry of Energy and Mineral Resources on 6 February 2012

will prohibit the export of unprocessed raw materials or ore by IUP holders. At this point, there

appears to be confusion as to the commencement date of the prohibition, with some government

officials saying May 2012, while others have indicated 2014.

Mineral raw materials will have to be processed in Indonesia, rather than being exported in a raw

state. This regulation is intended to develop the country‟s downstream mining industry, increase

domestic revenues, and ensure availability of refined products for domestic use. Sanctions for failure

to comply include suspension of activities and/or permit revocation.

4 Accessibility, Climate, Local Resources, Infrastructure and Physiography

4.1 Accessibility

The property area can be reached by road, approximately two hours‟ drive by vehicle from the

provincial capital Mataram. Domestic airlines provide a daily service to Mataram (1,100 km east of

Jakarta) either direct from Jakarta or transiting via Surabaya, or Denpasar. Alternatively, regular

daily sea ferries connect Lombok and its island neighbors of Bali and Sumbawa. Within the prospect

access is limited to a series of unpaved roads and foot-tracks that network across the area.

4.2 Local Resources and Infrastructure

Local infrastructure was sufficient to meet the majority of the company‟s logistical requirements

during the duration of the exploration program. Supplies or required services were sourced from the

administrative center of Mataram. There seems to be adequate supply of unskilled labour in the

immediate area of the property. Skilled labour for mining could be sourced from Indonesia and by

training the local population.

4.3 Climate

The area has a typical tropical wet climate and is subject to the seasonal influence of the northwest

monsoon from November to March, and drier southeast trade winds from June to September.

Rainfall in the mountain ranges to the north is between 1725-3500 mm per year and decreases

significantly to the coast with values of 1110 to 1850 mm per year being recorded. Daily

temperatures range from 26 to 31°C, which reduce to a low of 22 to 24°C overnight. Relative

humidity is also uniformly high, ranging from 80 to 100%.

4.4 Physiography

The prospect area comprises semi rugged terrain with incised valleys trending predominantly north

to northeast and northwest, reflecting the regional structural control. Elevations rarely exceed 350 m

reflecting the long period of uplift and erosion of the Miocene aged volcanic sequence (Figure 4.1).

As a result of population density and logging in the 1990s, the majority of hill slopes are denuded of

forestry and have been planted with cash crops such as rice and maize, along with lesser sweet

potato and bean crops. Two Community Forest (HTR) areas of 1,495 ha have been granted by the

Regency government within the forestry „pinjam pakai‟ permit area (refer to Figure 3.2). Southern Arc

would require permit holder approval prior to any drilling in these areas.



Figure 4.1: Typical landscape in the project area



5 History PT. Aneka Tambang, in conjunction with CV. Tanone Jaya, evaluated the area in 1978 but only base

metal mineralisation of limited economic potential was identified.

Following the withdrawal of Aneka Tambang, the area was incorporated by a local village

cooperative into three KP (mining license) areas DU.59-61 comprising 6,000 ha. Technical

assistance was requested from the Technical Directorate of the central Mines Department. Between

1981 and 1984 the Technical Directorate undertook ground geophysical (magnetics, IP/resistivity),

surface geochemical and geological surveys and a limited shallow diamond drilling program in the

KP areas. Surface sampling returned assay values including 3.2g/t Au, 430g/t Ag, 2.2% Cu, 15.23%

Pb and 30.9% Zn, whilst drilling encountered only narrow sub economic intersections (Rontek,

1985).

The entire SIPP area once formed part of the original 4th generation CoW area held by PT. Newmont

Nusa Tenggara‟s (PT NNT). PT NNT carried out an extensive stream sediment sampling program

that was followed up with a Bulk Leach Extractable Gold (BLEG) sampling program. The

geochemical sampling programs were followed up with ground magnetic and geological mapping

surveys which highlighted several porphyry targets in the Selodong area. Drilling by PT NNT

commenced in 1996 with 52 drill holes totalling 7,956 m. PT NNT abandoned the property in 1996 to

focus its efforts on the Batu Hajau deposit.

Southern Arc acquired the property in 2005 and initiated exploration on the property in 2006.

Exploration activity to date has included extensive geological and geochemistry mapping to establish

the presence of epithermal mineralisation and surface alteration, the collection of more than 4,500

surface channel samples across the property and 47,750 m of drilling at all three prospects.



6 Geological Setting and Mineralisation The island of Lombok is located in the central part of the tectonically active, east-west trending

Sunda-Banda magmatic arc that marks the convergence of three major tectonic plates (Hamilton

1979).

The geology of the West Lombok Property is characterized by an island-arc volcano-sedimentary

succession of Late-Oligocene to Quaternary age. A series of eroded, overlapping predominantly

andesitic volcanic centers and intermediate intrusive rocks make up the Tertiary arc. Intrusive rocks

include diorite, dacite, diatreme breccia and tonalite, the latter related to porphyry mineralisation at

Newmont‟s Batu Hijau mine and Elang deposit on the neighboring island of Sumbawa.

6.1 Regional Geology

The island of Lombok is located in the central part of the tectonically active, east-west trending

Sunda-Banda magmatic arc that marks the convergence of three major tectonic plates (Hamilton

1979).

The southern parts of Lombok Island are overlain by Late Oligocene to Middle Miocene, low

potassium calc-alkaline to weakly alkaline andesitic volcanic and interbedded volcaniclastic rocks,

associated low potassium intermediate intrusions and shallow marine sedimentary rocks and

limestone (Garwin, 2002). Overlying dacitic rocks are locally mapped in the region and mainly

occupy higher topography. The youngest rocks in the region are products of Recent and Quaternary

volcanism and are generally located in the north of the island, and have not been a focus of

exploration because of the limited exposure of the hydrothermal systems by erosion (Figure 6.1).

A series of eroded overlapping volcanic centres with associated fringing sediments make up the

Tertiary arc, and are represented by a thick pile of andesitic pyroclastics, flows, intermediate

intrusives, shallow marine sediments and limestones. The sequence is exposed over the south of

Lombok, with elevations up to 500 m. Tertiary rocks are also evident in the north of Lombok where

they are thought to form the basement rocks to more recent volcanism. Intrusive rocks are

commonly exposed in an east-west belt in southern Lombok. Older intrusives are commonly diorites

and microdiorites and occur as dykes and stocks intruding the volcanics and sediments. Later

tonalite intrusions are spatially and temporally related to the main porphyry Cu-Au mineralisation,

whereas older dioritic intrusions and stocks are related to earlier similar mineralisation types but

commonly lower grades (0.2% to 0.4% Cu). Diatreme dome breccia complexes have been mapped

peripheral to dacite porphyry intrusives. Dacitic pyroclastic rocks unconformably overly the andesitic

sequence. A thick blanket of volcaniclastic rocks (debris flow sequence) are locally preserved in

areas of structural complexity.

Based on a north-south compressive regime since the Late Miocene, regional structures comprise

north-south extensional faults, east-west trending reverse or thrust faults and folds, and a conjugate

strike-slip fault set with north-north westerly and north-north easterly trends. This structural regime is

thought to have arisen through counter-clockwise rotation of the regional maximum horizontal stress,

between the Middle Miocene and Pliocene, resulting in reactivation of a sinistral strike-slip

movement along the north-northeast trending structural zones. This regime of sinistral wrenching in

turn would have led, in blocks affected by this deformation, to the development of north-northwest



trending tensional faults/fractures, east-northeast trending reverse or thrust faults and secondary

conjugate strike-slip fault systems (Pieters, 2004).

(Source Campbell, 2010)

Figure 6.1: Regional geology setting

6.2 Property Geology

The IUP area covers the majority of prospective Oligo-Miocene andesitic volcano-sedimentary

succession and sub-volcanic intrusive rocks located in an east-west belt across the southern part of

Lombok. Mapping by Southern Arc has located a series of epithermal and porphyry style targets

along this belt.

Based on historical and geological mapping by Southern Arc (Campbell, 2010), the stratigraphic

units encountered on the property can be described as follows. The Pangulung Formation (Tomp) is

the oldest rock unit exposed in the study area. It was previously termed the “Old Andesite Formation”

by Van Bemmelen, 1949. The Formation comprises breccia, lava and tuff with limestone lenses

which are host to sulphide mineralisation. Inter-fingered with the Formation are alternating quartz

sandstone, claystone and breccia lithologies of the Kawangan Formation (Tomk). Previous authors

assume that these lithologies were formed on the flanks or proximal to the Oligo-Miocene volcanic

arc chain. Mid Miocene intrusions (Tmi), the source of hydrothermal alteration and mineralisation,

include porphyritic andesite, hornblende diorite, quartz diorite, feldspar porphyry, tonalite and

intrusive diatreme breccia in the appropriate chronological order (Clode and Pratama, 2002). Outliers

of late Miocene limestone and arenite (Ekas Formation – Tme) are found as capping topographical

highs, or in coastal areas along the western and eastern license boundaries. Plio-Pleistocene

alternating calcareous breccia and lava of the Kalipalung Formation (TQp) predominate in the

northern margins of the IUP. Holocene sedimentation (Qa) has resulted in the deposition of alluvial,

littoral and coral reef deposits on coastal and lowland plains. Fanglomerate outwash plains and



localised gravity flow deposits are noted along river terraces and coastal areas. Figure 6.2 shows an

idealised stratigraphic column of Southwest Lombok Island.


Figure 6.2: Idealized stratigraphic column of Southwest Lombok Island



Andesitic Volcanics (Tomp)

These early Oligocene-late Miocene lithologies are encountered over most of South Lombok, and

form a thick “basement” pile of ash to lapilli sized pyroclastics, lava flows and debris flows to fluidized

breccias of andesitic composition. These lithologies often exhibit weak lower greenschist facies

metamorphism, together with intercalated meta-volcanics/sediments, hornfels and garnet-

magnetite±biotite skarns.

Volcanic Sediments (Tomk)

These sediments consist of bedded shallow marine tuffaceous sandstone, siltstone, polymictic lithic

breccias and epiclastic tuffs. Minor intercalations of carbonates occur locally. Miocene-aged

Foraminifera have been described from the tuffaceous sediments, suggesting a possible Miocene

back-arc basin environment. Both volcanic and metavolcanic equivalents often inter-finger with

Tomp lithologies.

Diorite Porphyry Intrusives (Tmi)

These occur as north to north-northwest and east to northeast structurally controlled stocks which

intrude the Tertiary basement. The diorites consist of fine to medium grained (up to 3mm)

plagioclase and hornblende phenocrysts in a finer grained matrix. This unit is the main host to the

main porphyry Cu-Au mineralisation within the Selodong Intrusive Complex.

Feldspar Porphyry Intrusives (Tmi)

These occur as north to north-northwest and east to northeast structurally controlled stocks and

dykes (5-30 m width) which intrude the Tertiary basement. This lithology consists of coarse grained

zoned feldspar phenocrysts (up to 7mm) and minor hornblende and quartz phenocrysts in a finer

grained groundmass.

Plagioclase-Hornblende Andesite Intrusive (Tmi)

Mapped as both stock and dyke intrusive bodies that outline N to NNW and ENE structural elements.

Phyric textured with plagioclase and hornblende phenocrysts (up to 3mm) in a finer grained

groundmass.

Quartz Diorite Porphyry Intrusives (Tmi)

North to northwest structurally controlled stocks, which cross-cut earlier intrusive phases and

Tertiary basement. Intrusives consist of coarse to fine grained (up to 5mm) hornblende, plagioclase

and quartz phenocrysts in a finer grained matrix.

Magmatic Intrusive Breccia (Tmi)

Surrounds remnants of stockwork Cu-Au porphyries at Montong Botek and Lapangan Geres,

coinciding with circular features as defined by remote sensing studies. Monomictic to polymictic

clast-supported to locally milled and fluidized breccias with clasts (Tomp, Tomk and Tmi) from

centimetres to tens of metres in size, in a matrix of crystalline igneous material.



Hornblende Diorite Porphyry Intrusives (Tmi)

These occur as dykes and small stocks (1-100 m thickness) within the Oligo-Miocene volcanics and

associated sediments. They consist of medium and coarse grained (up to 5mm) hornblende and

plagioclase phenocrysts in a finer grained groundmass.

Dacite Porphyry Intrusives (Tmi)

These occur as dyke, plugs and sill like bodies intruding the Tertiary volcano-sedimentary pile. They

consist of medium to coarse grained (up to 5 mm) plagioclase, quartz and mafic phenocrysts in a

finer grained groundmass.

Dacite Volcanics (Tmv)

This sequence consists of ash to lapilli sized pyroclastics and occasional interbedded dacitic/rhyolitic

lavas. Exposures are limited to isolated outliers, capping higher topographic relief, where they

unconformably overlie andesitic volcanics and dioritic intrusives or limestone.

Epiclastic Breccia

This sequence of bedded and massive debris flow exhibit inverse graded bases. The dominant

clastics are andesitic and basaltic lavas, diorite and rare dacite. This unit primarily occurs as isolated

outcrops along the southern coast of Lombok Island.

Tertiary Limestone (Tme)

This generally massive bedded limestone may contain coralline coral fragments, calcareous

volcaniclastic sandstone intercalations and occasional chert and silicified horizons. It generally

occurs unconformably on, or as lenses within, the andesitic volcanic rocks.

Quaternary Deposits (Qa)

This unit consists of unconsolidated gravels, sand, silt, mud, air fall volcanic ash and organic

elements. Alluvium includes river sediments, estuarine deposits in the various bays and estuaries

with tidal flats, sand beaches and mangrove swamps.

6.3 Mineralisation

Mineralisation on the property has been separated into three main prospect areas, from North to

South, the Pelangan, the Mencanggah and the Selodong Prospects. Each prospect consists of

several mineral targets or deposits, many of which have been the subject of exploration by diamond

drilling.

6.3.1 Pelangan Prospect

The Pelangan Prospect covers an area approximately 4 x 5 km in the northwest part of the property

(Figure 6.3). The prospect comprises four main epithermal gold targets including Tanjung-Jati, Kayu

Putih, Raja and Lala. Southern Arc has completed 13,233 m of drilling in 99 holes on the Pelangan

Prospect. Phase 1 drilling was completed in 2007, together with semi-detailed geological mapping

and outcrop channel sampling of sub-parallel vein structures. Phase 2 drilling began in 2010 and

was focused on identifying and defining high-grade shoots within large continuous structures. Drilling



showed that mineralised breccia bodies ranged in true width between 3 m and 20 m. Phase 2 drilling

confirmed high-grade events typical of epithermal boiling zones at both the Central Raja and

Tanjung Lode structures and identified three high-grade shoots.

6.3.2 Mencanggah Prospect

The Mencanggah Prospect comprises a large cluster of west-northwest to north-trending, gold-

bearing epithermal mineralised structural breccias concentrated in a 6.5 x 4.5 km area in the centre

of the property, with the potential to host copper-gold porphyry mineralisation at depth. Channel

sampling indicates that these breccia bodies range in true width between 3 m and 66 m. The Bising,

Tibu Serai and Waterfall targets have been drill tested and show encouraging results. Surface

channel samples at the Tibu Serai target have returned the highest-grade mineralisation on the

property to date. Southern Arc has completed 14,380 m of drilling in 69 holes on the Mencanggah

Prospect. Drilling has demonstrated that gold mineralisation is associated with quartz veining

associated with wider mineralised structural breccia zones.

6.3.3 Selodong Prospect

The Selodong Prospect is situated in the southern part of the West Lombok Property. Drilling in the

Selodong porphyry copper-gold target was first carried out by Newmont in 2005 when they drilled a

total of 52 holes targeting porphyry copper mineralisation. Southern Arc added an additional 33

holes in the Selodong area between September of 2008 and October 2012 for 20,046 m. These

holes tested seven of the 14 porphyry copper-gold targets, with the majority intersecting broad zones

(126.45 m to 855.11 m) of significant copper-gold mineralisation. Drilling identified copper gold

porphyry style mineralisation associated with altered diorite intrusions. Typical porphyry alteration

assemblages are generally zoned outward from higher grade mineralised cores, though these

assemblages are often obscured by variations of incipient-weak through to intense post-

mineralisation overprinting and post-mineral brecciation. Secondary biotite was identified in core

logging and has been confirmed by petrological studies along with the presence of K feldspar.



7 Deposit Types There are at least two different deposit types present on the West Lombok Property; porphyry

copper-gold and epithermal gold mineralisation have been identified thus far.

7.1.1 Porphyry style mineralisation

Porphyry mineralisation was discovered at Selodong in 1992 by PT NNT. Surface mapping and

sampling defined several areas of anomalous Cu-Au mineralisation.

Copper-gold mineralisation is associated with late Miocene diorite intrusive rocks emplaced into Late

Oligocene to Middle Miocene low-K calc-alkaline to alkaline andesitic volcanic and subvolcanic

intermediate intrusive rocks. The two main types of mineralisation found in the property include

diorite hosted porphyry Cu-Au and related high to intermediate-sulphidation epithermal Au-Ag

mineralisation hosted in mineralised structural breccias. Mineralisation is almost exclusively

associated with quartz-sulphide stockwork veining and adjacent sulphide disseminations in the

potassic altered diorite. Two phases of diorite have been identified hosting stockwork mineralisation

with an earlier, more intensely altered, mineralised and veined quartz diorite.

Hypogene minerals include pyrite, magnetite and chalcopyrite along with minor bornite, chalcocite,

and sphalerite. Secondary minerals include malachite, azurite and chrysocolla, limonite, hematite,

and jarosite. Chalcopyrite is the dominant copper sulphide species, with bornite occurrences

generally more localised with notable zones of higher concentrations. No significant increases in

concentrations of bornite were noted with depth or along strike based on the current density of

drilling. Pyrite and magnetite are the most common minerals, with pyrite becoming more common

outwards from higher grade mineralisation. Magnetite is abundant throughout the mineralised

system and is associated with the potassic assemblage and porphyry mineralisation.

7.1.2 Epithermal gold mineralisation

The term “mineralised structural breccia” (“MSB”) has been applied by Southern Arc to describe

steeply-dipping, tabular silica-rich bodies that are associated with advanced-argillic alteration of the

adjacent host-rocks at the Pelangan and Mencanggah prospects (Figure 6.3). The silica bodies

range in thickness from a few meters up to 30 m and extend more than 1000 m along strike at

Pelangan and are up to 100 m wide and form zones more than 1000 m long at Mencanggah.

The down-dip extent of the bodies exceeds 300 m, as indicated by the surface trace of the bodies

and drill results at Pelangan. The silica bodies contain variable amounts of fine-grained massive

quartz, dickite, alunite, diaspore, pyrophyllite and pyrite/marcasite (converted to goethite and

hematite near-surface) and display breccia textures locally. Minor amounts of enargite and covellite

also occur in the silica-pyrite matrix (Allen, 1990). Gangue minerals include quartz chalcedony and

clay minerals.

Drill results show that these quartz veins form zones that are typically 5 - 20 m wide and contain

significant Au and Ag and anomalous As, Bi, Cu, Pb, Sb and Te; particularly where the quartz veins

are associated with fine-grained sulphide bands.



8 Exploration Following the incorporation of the ex-Newmont Block I in December 2005, Southern Arc received a

substantial geological database (including half drill core) generated from exploration activities

conducted in the Pelangan-Mencanggah-Selodong area during 1987-96.

8.1 Pelangan Prospect

A preliminary reconnaissance exploration program in the area was undertaken by Southern Arc in

November-December 2003. Field activities focused mainly on channel and rock chip sampling of

potentially mineralised outcrop exposures, but where outcrops were not exposed, samples of talus

scree were collected. A number of rock chip (RC) and rock float/talus scree (RF) samples were

collected along the eastern margin of the Pelangan epithermal system. Evidence of both low and

high sulphidation epithermal mineralisation was defined, with vein measurements analogous to the

Pelangan north-northwest trends. Low to moderate geochemistry was reported with values including

RC: 0.10-0.45 g/t Au, 1-17 Ag, and 0.06-0.28% As, while RF equivalents reported values of 0.03-

1.10 g/t Au, 1-65 g/t Ag, 3-160 g/t Sb and 6-227 g/t Mo, respectively.

A total of 210 BLEG, 210 stream sediments, 6 rock chips and 14 rock float samples (including

duplicates and check samples) were collected in the Pelangan-Mencanggah area and submitted for

analysis.

Ground traverses were conducted using tape and compass surveys tied into previously established

base lines along major ridge lines, along with global positional system (GPS) units for ground

control. Later detailed surface evaluation programs involved the usage of DGPS for mapping and

infill sampling along the MSBs. Mapping of lithologies and alteration facies follow the common

conventions of hydrothermal system definitions and nomenclature adopted by most workers

worldwide, and was further supplemented by the collection of petrological samples dispatched to

SKM - New Zealand. Rock chip and channel samples were collected on a routine basis during

preliminary stream and ridge traverses. A large variety of host rocks were also assayed in order to

determine the possibility of any bulk-tonnage potential, as well as to gain a geochemical signature of

the prospect as a whole.

Where previous Newmont rock channel cuts were identified, duplicate sections were collected.

Results from this duplication work provided good correlation with that of previous Newmont sampling

and thus both data sets were subsequently combined. In all, a total of 4,101 channel (CH) and chip-

channel samples (RC), together with 147 float samples (RF) collected from mineralised and altered

rock exposures/talus throughout the property (including duplicates and check samples) were

submitted for analysis.

In order to define the linear signature as well as establish some depth potential of resistive (silica

tabular bodies) zones, the company conducted a ground controlled Source Audio frequency

Magnetotelluric (CSAMT) survey over parts of the Kayu Putih, Tanjung and Raja targets in 2006.

Three survey grids at 50 m line spacings were established at differing orientations (090°, 315° and

335°) over the Kayu Putih, Tanjung, Raja-Ratu and Lala target areas. Survey recording stations

were established at 18 m horizontal intervals. The CSAMT survey was undertaken by geophysical

contractor PT. Elliot Geophysics and commenced mid-August 2006. Electrical and mechanical



problems combined with heavy seasonal thunderstorms plagued the survey, which was abandoned

in the third week of December with 40 lines totaling 24.3 km completed.

In general, near surface resistors correlate reasonably well with mapped MSB bodies; however, with

depth resistors tend to migrate northwards and westward and are most likely associated with

andesite and diorite intrusions (Figure 8.1). The more northerly northwest trending MSB are

indicated as resistors on the shallower plan sections, although they seem to die out to the east.

Aeromagnetic data confirms a northwest to southeast direction, but very likely responses are due to

andesite intrusions. The more southerly east-west striking MSB zone has good correlation in the

upper elevations; whilst further to the southwest strong resistors are noted, although no MSBs have

previously been mapped.

Results from BLEG geochemistry (Figure 8.2) confirmed the presence of elevated Au-Ag anomalies

throughout the Pelangan-Mencanggah Prospect areas. Priority 1 targets (>15ppb Au ± >75ppb Ag)

were identified from known MSB bodies Kayu Putih, Ratu, Raja, Lala, Simba, Gawah Bongor, Tibu

Serai & Waterfall/Mahoni. Priority 2 targets (3-15ppb Au ± 40-75ppb Ag) were attributed to

mineralised subsidiary structures as is the case at Mendorot (Lala East and recently defined

porphyry mineralisation), Simba West (Batu Putih porphyry trend), whilst others in the eastern parts

of the prospect area are along strike of the Blongas-Lapangan Geres porphyry corridor, reflecting the

combination of porphyry Cu-Au and later overprinting MSB styles of mineralisation. Low level BLEG

copper values (15-34 ppm) highlight porphyry mineralisation from the Blongas-Lapangan Geres

porphyry corridor and possibly the Mendorot-Gawah Bongor area. Stream sediment gold

geochemistry, in general, mimicked that of corresponding BLEG anomalies.




Figure 8.1: Results of the CSAMT survey in the Pelangan Prospect




Figure 8.2: Results of BLEG sampling program in Pelangan-Mencanggah Prospect areas



Geological mapping and sampling at Pelangan and Mencanggah has covered an area of 35 km2.

Detailed mapping using tape and compass (Pelangan) and DGPS (Mencanggah) was carried out

along creeks, ridgelines, and foot trails throughout the prospects, with the DGPS simultaneously

recording elevation for contour maps. Factual and interpretative geology, sample location and assay

maps were produced at 1:50,000, 1:10,000 and 1:5000 scales.

The company‟s work identified extensions to the known MSB targets and defined new targets

including Lala, Tibu Serai, Telekur, Talat Talat, and the Gunayang-Mahoni trend. Due to thick

secondary re-growth after logging, all drainages were systematically opened and outcrops cleaned

to gain better exposure of alteration, lithology, structure and any stockwork densities.

Surface mapping and later shallow scout drilling at Pelangan have defined extensive, structurally

controlled, epithermal gold-bearing breccia zones, occurring over an area of 3 x 2 km. Five major

zones (Raja, Kayu Putih, Tanjung-Jati, Lala and Ratu) comprising an aggregate strike length of

approximately 4.6 km have been defined. Channel sampling in conjunction with continuous rock chip

sampling (1-5 m widths) was used extensively to complement geologic mapping to establish priority

drill-test targets. The amount of costeaning was limited due to time constraints and negative

environmental impact on local cash cropping areas.

Raja: The Raja MSB comprises a 1.7 km long north-northwest trending mineralised, linear breccia

zone which has been subdivided into north, central and southern zones (Figure 8.3). The north-

northwest trend of Raja is a secondary structure related to the dominant 320° orientation which hosts

numerous mineralised breccias and porphyry occurrences within the property. At surface the Raja

MSB exhibits a „pinch and swell‟ character with zones up to 20 m wide.

North Raja: Outcrop samples (n=13) averaged 1.31 g/t Au and 22.7 g/t Ag, with maximums of

6.02 g/t Au and 98.0 g/t Ag. Limited trenching returned significant intercepts of 4.0 m @ 2.34 g/t Au

and 14.3 g/t Au (including 1.0 m @ 5.60 g/t Au and 29 g/t Ag) and 5.0 m @ 1.99 Au and 12.5 g/t Ag.

Central Raja: Systematic outcrop sampling (n=125) of prominent bluffs on the north side of the main

river averaged 2.17 g/t Au and 16.4 g/t Ag, with values ranging from <0.005 to 23.77 g/t Au and 1-

170 g/t Ag. In higher elevated areas to the south (South Raja) gold and silver values (n=38) declined

to an average of 0.84 g/t Au and 11.9 g/t Ag, with values to a peak of 6.17 g/t Au and 79 g/t Ag.

Ratu: Encouraging results were received from sub-outcrop samples (n=70, ranging from <0.005 to

34.1 g/t Au and <1 to 16.4 g/t Ag). Narrow mineralised drill intercepts suggest that Au-Ag

mineralisation is related to “horse-tail” splay structures developed between the Raja and Tanjung

MSBs.

Lala: First-pass mapping has been completed over the Lala MSB which parallels the Raja MSB

350 m to the east. Mapping has defined a series of mineralised structures oriented between north-

northwest and east-west over a 1.6 km strike length. Mineralised exposures comprise outcrops up to

15 m in width in the southern zone but generally are limited to discontinuous sub-crops to the central

and northern zones. Assay results from 314 rock-chip samples collected show consistently elevated

grades along the length of the structure, with an average grade of 1.29 g/t Au, 16 g/t Ag and 34 g/t

Mo. Variation in assay values range from 0.01-55.0 g/t Au, 1-178 g/t Ag and 4-365 g/t Mo.




Figure 8.3: Surface sampling results for the Raja Deposit, Pelangan Prospect



The Lala structure intersects a large diorite intrusive at the southern end where corresponding Mo +

Cu values are elevated (Batu Seni). This is of significance to exploration as potasically altered diorite

has been cored at South Raja and intense CSAMT anomalies occur between the southern parts of

the Lala and Raja MSBs.

Tanjung-Jati: The Tanjung-Jati MSB comprises a 1.5 km long northwest trending structure divided by

a central split/jog to form Jati to the west and Tanjung to the east. The northwest trend of Tanjung-

Jati parallels the dominant regional 320° orientation (Figure 8.4). Individual breccia zones exhibit a

„pinch and swell‟ character with zones up to 20 m wide. Outcrop sampling was somewhat

intermittent, due to discontinuous rock exposures and subdued topography in places. The 71

samples collected ranged from 0.01-31.1 g/t Au and 1-184 g/t Ag, averaging 1.93 g/t Au and 8.3 g/t

Ag.

Kayu Putih: The Kayu Putih MSB comprises two intersecting mineralised structures with east-west

and northwest trends, over an area of 800 by 400 m (Figure 8.5). The east-west oriented structure is

inferred to be hosted within „en-echelon ramp-structures‟, which can be associated with high-grade

mineralisation. Results of outcrop sampling (n=188) highlight the higher grade potential of the

eastern half of the east-west MSB structure and the southeast end of the 320° trending structure.

Average grades within these areas (n=122) are 10.36 g/t Au and 10.5 g/t Ag, with values ranging

from 0.03-303 g/t Au and 1-98 g/t Ag. Channel samples collected in the vicinity of visible gold

identified in outcrop exposures returned intercepts of 6.8 m @ 22.43 g/t Au, 0.9 m @ 34.6 g/t Au and

2.7 m @ 7.1 g/t Au and 21 g/t Ag. Higher grade zones coincide with cross-cutting gold-silver telluride

bearing quartz veins with localised hydrothermal brecciation that overprint earlier structurally-

controlled “silica ledges”. Outside of the higher grade zones, veining is sporadic and thus assay

values (n=66) decline to an average of 0.62 g/t Au and 10.3 g/t Ag.

Simba: The Simba vein system is traceable along strike for 1.6 km striking between north and

northwest and dipping between 60° to 75° southwest. Vein outcrops are typically “pinch and swell”

and vary between 1 and 30 m wide with individual lenses between 30 to 150 m long. Vein swells

appear to be associated with north-south structural intersections and vein junctions. Vein zones are

characterized by irregular breccias with locally developed banding of fine to medium-grained

saccharoidal quartz, drusy cavities, and localised vuggy textures. Strong silicification is developed

peripheral to veins for up to several meters within the host rock. Thirty one continuous rock chip

samples were collected along outcrops and residual PT NNT trenches, but results from these largely

failed to replicate grades seen in PT NNT trench samples (Figure 8.6).

8.2 Mencanggah Prospect

Channel sampling was used extensively at Mencanggah to complement geologic mapping and

establish prioritized MSB targets. A total of 1,191 rock chips and channel samples were collected

during mapping. Sample assay results are outlined in Figure 8.7.

Channel samples were collected using a combination of hammer and chisel and portable rock saw.

Channel sampling intervals along strike of the MSBs range from 25 to 100 m. Channel sample

widths generally range from 1 to 5 m depending on exposure and down to a minimum of 10 cm for

individual vein character samples.



(Source Rowe, 2008)

Figure 8.7: Surface rock samples collected from the Mencanggah Prospect



The Bising target forms a prominent hill in the western part of the prospect comprising a west-

northwest trending MSB body approximately 700 m long by up to 100 m at the widest point

(Figure 8.8). Historical sampling by PT NNT indicated the significance of the structure with results

including 228.0 g/t Au from a 2.0 m channel sample. Southern Arc sampling along the Bising

structure confirmed the localised high-grades at surface with results including:

2.0 m @ 38.96 g/t Au

2.0 m @ 17.45 g/t Au

66.0 m @ 1.09 g/t Au (incl. 3.0 m @ 8.6 g/t Au)

5.0 m @ 5.52 g/t Au

The 365 channel samples collected at Bising returned an average grade of 1.17 g/t Au with a peak

result from a 1.0 m channel of 71 g/t Au. Silver values are generally subdued with an average result

of 1.55 g/t Ag and peak of 22.0 g/t Ag.

The Tibu Serai target occurring in the northern section of the prospect covers a broad 1,300 by

600 m area comprising more than 12 individual MSBs, (TS1 to TS12) (Figure 8.9). Individual MSBs

strike northwest to north-northwest with maximum length of 1,000 m and width up to 20 m. Southern

Arc surface sampling confirmed localised zones of high-grade mineralisation at Tibu Serai including

the following highlights:

TS3: 2.5 m @ 6.12 g/t Au

TS3: 7.1 m @ 53.53 g/t Au

TS6: 3.0 m @ 2.52 g/t Au

TS9: 2.0 m @ 3.59 g/t Au

TS9: 1.1 m @ 12.0 g/t Au

From the 417 channel samples collected at Tibu Serai the average gold grade is 1.79 g/t Au with a

peak value of 116.0 g/t Au. Silver is again subdued with an average grade of 1.3 g/t Ag with a peak

value of 21.0 g/t Ag.

The Waterfall target occurs in the southwest of the prospect area forming a 750 m long northwest

trending sigmoidal-loop structure, in places up to 40 m wide (Figure 8.9). Though relatively lower

gold grades have been encountered at this target, quartz vein textures and the inferred presence of

adularia are indicative of high levels of exposure. The potential therefore exists for an epithermal

system with potentially un-exposed higher grade zones in close proximity. SA sampling has

confirmed consistent lower grade anomalism along the structure with results including:

8.0 m @1.42 g/t Au

2.0 m @ 1.41 g/t Au

One hundred and eighty seven channel samples collected at Waterfall returned an average grade of

0.35 g/t Au with a peak assay of 2.89 g/t Au. Silver grades are low with an average result of 4 g/t Ag

and a peak value of 42.0 g/t Ag.



Character sampling at Mencanggah suggested at least two mineralizing events that contributed

metal deposition in the prospect areas. Gold assay values from silica pyrite advanced-argillic altered

volcanic ranges from 0.05 g/t Au to 0.50 g/t Au, whereas later banded quartz veining and

hydrothermal breccias formed by what appears to be the same generation of quartz range from

0.1 g/t Au to 250.0 g/t Au.

8.3 Selodong Prospect

Evaluation of the PT NNT database along with the available drill core resulted in the definition of

fifteen priority targets which included the previously drill tested targets of Montong Botek, Blongas I

and II, Belikat and Kekalik (Figure 8.10). The other ten targets were ranked based on follow up

detailed DGPS mapping and sampling. The Kedaro and Lepangan Geres targets were subsequently

drill tested. Along with surface mapping and sampling to enhance and verify the existing data set,

Southern Arc undertook 3D modelling of the Newmont ground magnetic data by GRS - Australia and

selected petrographic analysis of drill core from Montong Botek and Blongas II by SKM - New

Zealand.

Previous PT NNT data were verified in the field where possible through duplication of geochemical

samples, ground truthing of geological traverses and drill collars. All PT NNT drill collars were re-

located and DGPS surveyed to UTM-WGS84 as the earlier PT NNT work programs were based on a

local grid. Based on this rectification, all PT NNT data sets were converted to UTM.



(Source Rowe, 2008)

Figure 8.10: Surface sampling for the Selodong Prospect



Ground traverses were conducted between June 2007 and May 2008 within the 7 x 3 km area of the

Selodong Prospect area. Detailed mapping using DGPS carried out along creeks, ridgelines, and

foot trails throughout the Selodong Intrusive Complex (SIC) simultaneously recorded elevation to

produce digital elevation and geological maps at 1:5000 scale. The distribution of lithological units

and alteration facies generally agreed with Newmont‟s original mapping. Apart from the well-exposed

mineralised quartz diorite outcrops at Montong Botek and along one of the creeks at Blongas II,

porphyry mineralisation in general is very poorly exposed at Selodong due to weathering

characteristics and the labile nature of highly altered porphyry mineralisation. Due to thick secondary

re-growth after logging, all drainages were systematically opened and outcrops cleaned to gain

better exposure of alteration, lithology, structure and any stockwork / fracture densities. Mapping

identified mineralisation and alteration types, defined the approximate limits of post-mineral

brecciation around Montong Botek and Kekalik and the dimensions of post-mineral hornblend diorite

dikes and elucidated some of the major structure controls on mineral and post-mineral events.

Southern Arc ground traverses further developed the significance of the Kedaro target to drilling.

Deposits of porphyry mineralisation were extended a further 7 km northwards, along the Montong

Botek porphyry trend, to Lepangan Geres and Gawa Bongor; another new porphyry style

mineralised area located a further 7.6 km to the north. Detailed mapping has identified the main

controls of porphyry mineralisation at Selodong and shown key porphyry hosting structures

extending outside of Selodong the north and northwest.

Porphyry mineralisation is generally not well exposed due to the labile nature of alteration mineral

assemblages and therefore anomalous samples give a positive sign of mineralisation rather than an

indicative grade. It should also be considered that Lepangan Geres has proportionately more

sampling as this was a new discovery and had not been sampled by the previous operator. Targets

such as Blongas II and Montong Botek have not been as heavily sampled because of previous

surface work and drilling by PT NNT.

A total of 1,082 surface outcrop rock chip and channel samples were collected and analysed for

gold, copper and molybdenum. Normal tropical weathering conditions have resulted in oxidation of

copper sulphides to shallow levels (generally 5 to 20 m below surface), resulting in subdued surface

copper-geochemistry. Gold is intimately associated with copper mineralisation and, being relatively

less mobile at surface, is a better indicator of mineralisation in this instance. At concentrations > 0.15

g/t Au and in the presence of quartz-stockwork and well developed fracturing, gold was considered a

good indicator at Selodong for porphyry mineralisation. Accordingly, a 0.1 g/t Au cut-off has been

applied for the following summary of rock-channel statistics.

Montong Botek: Mineralised stockwork is discontinuously exposed along a 350 x 250 m north-south

elongate zone with the main high grade pod of mineralisation located at the southern end. Forty five

out of 68 5 m channel samples gave an average result of 0.2 g/t Au and 232 ppm Cu with maximum

values of 0.69 g/t Au and 753 ppm Cu.

Blongas I and II: Covers a north-south elongate zone of 940 x 240 m. A total of 104 1 - 3 m wide

channel samples were collected from generally sparse outcrops. Fifty two out of 104 channel

samples returned an average of 0.1 g/t Au and 232 ppm Cu with maximum values of 0.33 g/t and

834 ppm, respectively.



Kekalik: Alteration and anomalous geochemistry covers a broad area of approximately 700 x 600 m.

From 154 samples, 117 gave average values of 0.1 g/t Au and 228 ppm Cu with maximum values of

0.85 g/t and 2910 ppm, respectively.

Belikat: covering an area of approximately 740 x 640 m, reported average results from 65 out of 195

samples of 0.2 g/t Au and 873 ppm Cu with maximum values of 2.21 g/t and 14100 ppm,

respectively.

Kedaro: 66 out of 153 samples collected averaged 0.2 g/t Au and 303 ppm Cu with maximum results

of 2.21 g/t and 1350 ppm, respectively.

Lepangan Geres: a total of 407 rock samples have been collected within an approximate 600 x

300 m altered area. 231 returned an average grade of 0.2 g/t Au and 303 ppm Cu with maximum

values of 1.3 g/t and 3760 ppm, respectively.



9 Drilling Drilling has been carried out on the Pelangan and Mencanggah Prospect areas by Southern Arc and

on the Selodong Prospect by Newmont and Southern Arc. Drilling by Southern Arc was carried out

using up to seven drill rigs. The rigs are man portable, and have the capacity to drill PQ size

(85 mm), HQ size (63.5 mm) and NQ size (47.6 mm). Two of them can drill PQ to 130 m, HQ core to

350 m, and NQ to 650 m; the larger one can drill PQ to 200 m, HQ core to 550 m, and NQ to

1000 m. Triple tube drilling is used to maximize core recovery. Southern Arc indicates that the larger

core is drilled as much as possible.

The diamond drilling programmes were carried out by Indonesian drilling contractors PT Antero

Indodrill (2006 To 2008) and PT Promincon (2010 to 2013) under contracts to Southern Arc. Each

drill rig was operated by two direct employees of the drilling contractors, up to six local laborers, and

a field assistant employed by Southern Arc. The field assistant supervised the drilling, with additional

oversight from time to time during the day from site geologists. Down hole surveys of magnetic

azimuth and drill hole dip are made every 50 m using an Eastman single shot camera. Obvious

incorrect readings (affected by magnetic rocks or poor operator implementation) were discarded.

Collar locations are picked up by a contract surveyor using a differential GPS unit with a claimed

accuracy of ±1 cm. The DGPS base station is located at the West Lombok camp.

The core was transported daily from the rig site to the West Lombok exploration camp. A core

logging shed has been established under a thatched roof cover and partly in the open air. The core

area was reasonably orderly at the time of the site visit; a whiteboard is used to keep track of the

core trays on the racks and the current drilling.

On arrival at the camp, the core is washed and photographed. Two high resolution digital

photographs are taken of each core tray. The core photography setup is sufficient for the purpose of

routine recording of the core and the collection of geotechnical data. Clear core tray labeling is used

in the core photography and photos are reviewed by the site geologist to assure good photo quality.

Core logging was based on a Core Logging Manual prepared by Southern Arc. The manual is very

comprehensive and is based on the recording of all geological and geotechnical characteristics of

the drill hole sample using a coded input. The manual provides very detailed instructions on the data

that needs to be recorded as well as some training on the method of acquiring the data. Core logging

is carried out by local Indonesia geologists with oversight provided by Southern Arc senior geological

staff.

9.1 Pelangan Epithermal Prospect

Southern Arc‟s first phase of diamond drilling employed a small man-portable drill rig capable of

drilling to depths of 60 m HQ and 110 m NQ, designed, built, and supplied by PT. Antero Indodrill, a

Bogor-based drilling company. A network of tracks was constructed linking the drill pads, whilst core

logging/sampling/storage facilities were established in the northern part of the prospect area. The

program began with the collaring of the first hole, designated KDG-01, on June 28, 2006 and was

completed at the termination of RDG-14 on February 10, 2007. A total of 51 diamond drill holes were

completed for 3,762.05 m at an average recovery rate of 95.6% along the Kayu Putih, Raja-Ratu and

Tanjung-Jati MSBs as part of the first phase of drilling. All holes were drilled perpendicular to the



main MSB structures at inclinations of -55° to -60°. Drilling has tested an aggregate strike of

approximately 3.5 km at intervals between 50 and 150 m.

A second phase of drilling was carried out on the Pelangan area between 2008 and 2012 focusing

on higher grade shoot defined from the first drilling campaign. Southern Arc completed an additional

9561 metres of drilling in 48 holes at the Pelangan Prospect..

The majority of holes were drilled well past the MSB targets to explore for any parallel mineralisation

in the immediate footwall rock zone. Initially the entire half-core of each hole, regardless of

alteration/mineralisation, was sampled. This practice was subsequently changed to sampling only

zones of moderate to intense quartz veining, intense silicic altered zones, and the immediate

peripheries of those zones. A total of 5,703 half drill core samples were taken and dispatched to ITS

In general, targeted down-dip extensions of surface mineralisation were intersected with, aside from

southern Kayu Putih, comparable gold-silver values. In the case of southern Kayu Putih, drill

intercept grades (KDG-01 to KDG-05) are often a magnitude lower than surface outcrops,

suggestive of surface supergene effects. The main silica bodies/quartz veins were interpreted to be

largely vertical to sub-vertical, with a steep west-southwest dip; the most commonly recorded

attitude. A moderate to intense intermediate argillic (illite-smectite, kaolinite and dickite) altered

selvedge of varying widths (metres to 10s of metres) is a common feature on both the hanging wall

and footwall edges of the silica bodies/veins. This is often accompanied by strong differential

shearing resulting in strongly broken core (and slightly lower recoveries at the vein edges), both

leading to some uncertainty in determining vein attitudes.

The following are general observations of drilling results.

Raja MSB

Shallow drilling along the central and southern zones of the Raja MSB has confirmed continuity of

gold mineralisation within a 600 m strike length between drill holes QDG06 and RDG07. In this zone,

aggregated drill intersections of 128.4 m reported an average grade of 3.42 g/t Au and 19 g/t Ag,

over a vertical extent of 159.6 m (Figure 9.1). Higher grade zones are characterized by:

Quartz veins with fine-grained sulphide and telluride-mineral bands, swirls and clots located in

general along silica body/vein margins.

Low Au/Ag ratio of generally less than 5, elevated Te, Bi and Se values. Au and Te levels

appear to decline significantly at elevations higher than 275 m above sea level. Au/Ag ratios < 5

are typically ascribed in epithermal models and are inferred to lie near up-flow fluid zones; hence

prime targets for drill targeting.

Structural intersection of cross-cutting east to northeast and northwest traverse/tensional

fracture/fault zones with the main silica bodies / quartz vein systems.

All drill holes were cored at angles between 55° to 60° and spaced at intervals between 50 to 150 m

along strike, confirming a vertical to sub-vertical dip on the structure. Most of the mineralisation was

intercepted below the base of surface oxidation.



Drill sections suggest that orientations of quartz vein systems consistently dip 70°-90° to the

southwest; however, at Raja North (RDG013, RDG014 & QD006) a possible sub-vertical northeast

dip is inferred. Deflections in strike and dip of silica bodies/quartz veining are attributed to

reactivation of pre-existing east-northeast trending, transverse fault / fracture zones. In a number of

sections, vein systems are interpreted to bifurcate and coalesce at depth; however, peripheral

veining is also another option.

The program has confirmed the presence of extensive, near surface gold mineralisation within the

central and southern parts of the Raja MSB. Drilling intercepts are of a comparable magnitude to

earlier surface outcrop sampling.

Rock lithologies logged throughout the 14 drill holes show a consistent volcaniclastic sequence of

polymictic volcanic lithic breccia with local intercalations of volcanic sandstone and well-bedded

siltstone, later intruded by diorite, andesite and feldspar porphyry stocks and dykes (5 - 30 m wide).

Differences between individual holes are ascribed to lateral facies differences in volcaniclastics,

along with effects of post-mineralisation faulting.

As noted from petrology studies of drill core (RDG09 and 11), the occurrence of K-silicate and high-

temperature propylitic alteration assemblages, together with the presence of hydrothermal magnetite

in diorite and volcanic lithic breccia, evidences any early hot phase (>260°C) with clear magmatic

affinities. This early hot phase was later followed by cooler (190-240°C) acid to intermediate fluids,

evidenced by illite-smectite, kaolinite and dickite alteration (White, 1998).




Figure 9.1: Significant drill intercepts from the Pelangan Prospect, Raja MSB target



Ratu MSB

The five drill holes (QDG01-05) completed in this area targeted extensions below high-grade surface

rock-float/subcrop, but failed to intersect any major mineralised structures. The large volume of

locally high-grade material is now believed to be derived from the Tanjung MSB. Narrow mineralised

drill intercepts (QDG04: 1.4 m @ 4.9 g/t Au and 4.25 m @ 2.10 g/t Au/10.4 g/t Ag) are interpreted as

“horse-tail” splay structures developed between the Raja and Tanjung MSBs.

Tanjung-Jati MSB

Zones of potentially significant gold mineralisation have been intersected in 8 of 13 drill holes along

the 1.5 km strike length of the Tanjung-Jati MSB. Shallow drilling has confirmed continuity of

mineralisation to depths of around 50 m with locally high-grade intercepts. Like Raja, higher grade

zones are associated with quartz veins with fine-grained sulphide and telluride-mineral bands along

silica bodies and vein margins.

All drill holes to date have been cored at angles between 55° to 60°, and spaced at intervals

between 50 to 230 m along strike, confirming a vertical to sub-vertical dip of the structural breccias.

A change in dip direction between drill holes TDG07 and JDG01 most likely marks the effects of

movement of precursor east-northeasterly trending, transverse fault and fracture zones. In a number

of sections, vein systems are interpreted to bifurcate and coalesce at depth; however, peripheral

veining is also another option. Most of the mineralisation has been intercepted below the base of

surface oxidation and is generally comparable in magnitude to previous outcrop sampling.

Kayu Putih MSB

Encouraging gold-silver intersections were reported in 9 of the 17 holes drilled within the Kayu Putih

MSB area. Holes were drilled on a north-south grid orientation at intervals of 50-100 m, with

inclinations of -55° to -60°. The deepest mineralised intercept occurs at 59 m vertically below

surface, whilst the majority of intersections occur below the base of complete oxidation. Dips of the

intersected silica bodies / quartz vein structures vary between 60° to 90° northwards and are inferred

to bifurcate in a number of interpreted cross sections (Figure 9.2).

Drill results confirm the presence of near surface high-grade zones within the southeastern portion of

the mineralised structure. A 450 m long strike zone between drill holes KDG02 and KDG12 shows

the best potential for continuous high grade mineralisation. Within this zone, density of sulphide and

telluride bearing quartz veins is directly proportional to gold ± silver grades. Such vein types are

found predominantly along the margins of the silica body/ quartz vein system. Resistivity mapping

confirms the north-northwest migration of the structure with depth. Scissor holes (KD06 & 07)

confirm the northerly dip of the mineralised structure, effectively drilling down-dip in the intermediate

argillic alteration envelope.

Outside of the higher grade zone drill intersections reflect the predominance of silica ledges derived

from the early advanced argillic / potassic alteration event. Typically, drill intercepts are less than

0.2 g/t Au, but where sporadic quartz veins and breccias are encountered, values up to 3.52 g/t Au

and 41 g/t Ag (KDG09 and KDG14) are reported.

9.2 Mencanggah Prospect

Phase 1 exploration at the Mencanggah Prospect was carried out in 2011. Initial drilling activities

focused on the Waterfall target, where Southern Arc completed 27 holes for a total of 6,634 m of

drilling, with 17 of the 27 holes encountering gold mineralisation. Southern Arc then concentrated its

efforts on the Bising target. A total of 8 holes were drilled during the first phase of drilling and 16

holes during the second phase of drilling.

Drilling on the Bising target led to the identification of a continuous mineralised lens that is the focus

of extensive mining activity by artisanal miners (Figure 9.3).

(photo by SRK)

Figure 9.3: Photo of artisanal mining excavation areas on Bising Deposit

The extensive width, up to 60 m width in surface outcrop of the main Bising epithermal body is

inferred to result from the intersection of geological structures: a major west-northwest trending fault

intersected by several north-northwest trending faults, the latter of which form the dominant gold

mineralised trend in the West Lombok district.

Additional drilling was carried out on the Mencanggah Prospect at Tibu Serai, an area located

approximately 1 km north of Bising. Southern Arc drilled 16 holes totalling 2,397 m on the Tibu Serai

Deposit.



9.2.1 Mencanggah Drilling Results

Waterfall

Drilling at Waterfall below outcrops of banded and brecciated quartz veins intersected multiple

mineralised veins, some with encouraging gold mineralisation. Drilling tested a 2 km strike length of

the breccia zone and, of the 17 holes that encountered gold mineralisation, the best intersections

were found in holes MCG001 and MCG016. Drill hole MCG001 intersected 2.3 m grading 4 g/t gold

and hole MCG016 intersected 4.75 m grading 15.6 g/t gold 375 m north west of hole MCG001.

Follow-up drilling on the Waterfall returned mixed results with several holes returning only minor

mineralisation. Figure 9.4 summarises the drill results for the Waterfall area.

Figure 9.4: Drill results from the Waterfall area

Bising

Drilling at Bising focused on defining the vertical extent of the wide epithermal breccia body identified

in surface outcrops. The drilling demonstrated the consistency and width of mineralisation in the area

for over a 500 m strike length, with a large proportion of the drill holes intersecting wide intervals

averaging greater than 1 g/t gold mineralisation. Some of the more significant results include 53 m

grading 0.68 g/t gold in hole MCC057, 51 m grading 1.5 g/t gold in hole MCC028 and 26 m grading

1.22 g/t gold in hole MCC061. Figure 9.5 summarises the drill intersections for the Bising deposit.



(source Southern Arc New release, 2013)

Figure 9.5: Longitudinal section of the Bising deposit showing drill hole intersections

Tibu Serai

Eight of the initial nine holes drilled at Tibu Serai intersected gold mineralisation within a 220 m strike

length centred on MCG055 (Figure 9.6). Two holes drilled 40 m northwest and southeast of MCG055

confirmed continuity of high gold grades along an 80 m strike length at similar elevations. MCG058,

located 40 m northwest, intersected 6.90 m @ 5.65 g/t gold, while MCG060, located 40 m southeast

of MCG055, intersected 5.10 m @ 5.29 g/t gold.

MCG061 intersected mineralisation 60 m vertically below MCG055 (26.30 m @ 1.22 g/t gold

including 8.00 m @ 3.21 g/t gold), indicating continuity of mineralisation at depth. MCG067, located

approximately 120 southeast of MCG055, intersected high-grade mineralisation (4.50 m @ 7.79 g/t

gold) within a second shoot zone that remains open to the southeast.

Drilling has also intersected a parallel vein zone exposed 200 m to the southeast of MCG067

(Figure 9.4). A narrow high-grade intersection in MCG058 (0.70 m @ 13.50 g/t gold and 2.3 g/t

silver) well above the targeted mineralisation is interpreted to represent the strike extension of this

parallel vein zone.




Figure 9.6: Drill results from the Tibu Serai Deposit

9.3 Selodong Prospect

Historical Newmont drilling on the porphyry targets comprised 52 drill holes for a total of 7,956.5 m.

Forty eight shallow (150 m maximum) drill holes were completed with a man-portable Jakro Rig, and

four deeper holes (600 m) were drilled by a helicopter assisted Longyear 44 drill rig. Core drilling

was conducted using wire line recovery methods with PQ, HQ and NQ triple tube equipment. Core

recoveries were calculated for all core intervals; in general between 1.0 and 3.0 m, with bulk

samples up to a maximum of 27.7 m. Sampling comprised of splitting half the core with a diamond

saw, whilst half was retained. No detailed information is available on procedures followed.

Between April 2007 and September 2008, Southern Arc completed 30 drill holes for a total of

17,859.3 m of drilling and 8,576 half core geochemical samples. The drilling program was designed

on evaluation of the extensive PT NNT geological database. A five drill hole program was designed

initially to validate and extend the mineralisation previously drilled by PT NNT at Montong Botek and

Blongas II. Positive results were received from SLD001 to SLD005. Based on these results,

indications of other porphyry deposits from Newmont data and detailed mapping by the company

within the Selodong area, an additional seven targets were tested.

Sampling intervals were predominantly based on 2 m intervals and varied between 1-3 m based on

geological contacts. A total of 8,576 half core samples were collected including 279 standards and

135 blanks. Standards were inserted randomly within the sample stream and blanks were placed



within or immediately below highly mineralised zones to check for contamination during lab-assay

procedures. Samples were dispatched to ITS laboratory for analysis of Au, Cu, Zn, Ag, and Mo.

9.3.1 Selodong Drill Results

Drilling at Selodong focused on six discreet porphyry targets, Montong Botek, Blongass II, Kekalik,

Belikat, Kedaro and Lepangan Geres. At Montong Botek, Southern Arc has partially defined an

open-ended north-south elongate Cu-Au mineralised zone of 450 m long by up to 200 m wide. This

north-south trending mineralised zone lies within an area defined by SA drill holes SLD011, SLD013,

and SLD023 in the north and shallow Newmont drill holes PSG012 to PSG014 and PSG017 to the

south. SLD029 effectively closed off vertical extensions below high grade mineralisation in SLD001-

003 by post mineral brecciation. Some of the more significant drill intersections at Montong Botek

include 168 m grading 0.51% copper and 0.84 g/t gold in hole SLD001 and 855 m grading 0.10%

copper and 0.22 g/t gold in hole SLD023. Figure 9.7 summarises the significant drill intersections for

the Selodong Prospect including the drilling for the Montong Botek area.


Figure 9.7: Drill results for the Selodong Prospect



At Blongas II, Southern Arc drilled a total of eight holes that defined a north trending mineralised

dyke over a 900 m strike length but of relatively narrow width (50 to 200 m). Best results for

Blongas II include 407 m grading 0.25% copper and 0.45 g/t gold in hole SLD 004 and 406 m

grading 0.23% copper and 0.29 g/t gold in hole SLD005. Results for the other Blongas II drilling are

summarised in Figure 9.7.

Drill holes SLD009 and SLD010 were collared in the Kekalik target area to test below outcrops of

diorite intrusive with variable porphyry-style quartz stockwork veining. Hole SLD010 was collared

196 m west of SLD009 to test western portions of the same general target. Both drill holes

encountered porphyry Cu-Au style mineralisation and associated hydrothermal alteration, but Cu-Au

grades were relatively lower because of late-stage phyllic overprinting. Hole SLD009 reported only a

low grade gold intercept of 70.80 m at 0.18 g/t gold and holes SLD010 returned 32 m grading

0.16 g/t gold.

Two holes were targeted at Kedaro: SLD019 and SLD 027. Hole SLD 019 intersected 126 m grading

0.16% copper and 0.23 g/t gold. SLD027 was drilled 115 m south of SLD019; the previous drill hole

at Kedaro. The drill hole was positioned to test for potentially higher-grade mineralised extensions of

SLD019 and to see if significant mineralisation was associated with the large irregular 400 x 200 m

magnetic anomaly located immediately west of the drill collar.

SLD027 was drilled westward of SLD019 and encountered variably altered and weakly to non-

mineralised quartz micro-diorite. The Kedaro target remains interesting as mineralisation remains

largely unexposed at surface and localised zones of elevated surface geochemistry with supporting

magnetic anomaly occur along an 800 m plus along a northwest trend.

Three holes were targeted at the Lepangan Geres target (Figure 9.8). SLD021 was drilled near the

center of the main diorite porphyry body and intersected 142 m grading 0.07% copper and 0.14 g/t

gold. SLD025 was located 160 m north of SLD021 and drilled westward at an inclination of -70

degrees to a depth of 550.1 m. From surface to a depth of 196 m, variably phyllic over-printed and

weakly mineralised micro-diorite was encountered. This zone returned the only significant

mineralisation within the hole (Figure 9.8). Hole SLD028 did not encounter any significant

mineralisation.

9.4 SRK Comments

SRK is of the opinion that the drilling programs carried out by Southern Arc on the West Lombok

property are sufficient and adequately spaced for use in the estimation of mineral resources for the

Pelangan, Mencanggah and Selodong prospect areas.



10 Sample Preparation, Analyses, and Security

10.1 Surface Mapping Samples

For flocculated BLEG samples, moss aggregates, over-bank deposits and boulder cavities are

sampled vertically and the resulting material is wet-sieved through a minus 30 mesh sieve into a 10

litre plastic container. No water is allowed to escape from the plastic container and once a

substantial amount of sediment has been collected, an amount of flocculant (Magnofloc E30) is

mixed with the watery sediment until suspended clay material binds and aggregates together,

leaving clear water above the sedimentary mass. Water is decanted off and the sediment is placed

into a large calico bag, bound and squeezed to remove excess water. The sample is then double-

bagged using a large plastic bag. Samples are dried in the sun for a period of 5 to 7 days and then

shipped to the ITS prep laboratory. Average sample weight was 4 to 5 kg of dry weight. For every 25

sample sites there was a random duplicate sample collected at one site. An average sample density

of one BLEG site per 1.4 km² was achieved during the sampling program.

Because of the large sample size in BLEG sampling and the involvement and consistency of four

experienced survey crews, it is considered that results reported have a high degree of accuracy,

quality and reliability. Supporting this opinion is that the highest reported BLEG assay values

emanate from known mineralised prospect areas.

Minus 80# stream sediment samples were split off from the BLEG sample during sample prep at the

ITS laboratory.

For rock samples from potentially mineralised outcrop exposures, along with float from hill talus and

streams, standard sampling procedures involved first removal of any obvious surface crustiform

weathering and/or organic matter, followed by the collection of a representative sample of the

inferred mineralised rock material. For continuous 1 to 3 m outcrop samples, samples were oriented

perpendicular to any obvious mineralised structure. Any obvious surface crustiform weathering

and/or organic matter was first removed, followed by a continuous channel of HQ/NQ core

proportions using either a rock chisel and hammer, or Stihl TS50 rock saw. Emphasis was placed on

collecting a uniform representative sample over the channel width to avoid sample bias. Where vein

samples were sampled these were either:

a. sampled as a single continuous channel sample from one vein margin to the other, or

b. sampled as a chip sample because of vein width less than 15 to 20 cm, or

c. sampled as a continuous chip sample of 3 to 5 m to ascertain potential grades in preliminary

ground traverses.

Samples were described, numbered with relevant rock code (CH=channel, RC=rock chip or RF=rock

float), bagged with relevant sample tickets and temporarily stored at the company base camp. Hand

specimens of all samples were retained for future reference. Separate check samples from Gannet

and Windrift Australia along with blanks were submitted in a random fashion to approximate one

check sample per 25 rock samples collected.



10.2 Drilling Samples Preparation and Analyses

The core sample intervals are marked directly on the core with a fibre-tip marker, and the sample

numbers assigned by the geologist are marked on red core blocks. The core is then cut in half with a

diamond core saw. The orientation of the cut of each piece is chosen as the most convenient by the

operator and a random half added to the sample and the saw is cleaned with water between

samples to minimize contamination. Both halves of the sawed core are replaced in the core box and

the sample is collected for bagging at a sample station controlled by the geologist.

The core halves for the sample are placed in a numbered calico bag, and pre-printed waterproof

sample tags are inserted. The sample details are filled out into the sample book and these are cross-

checked by the geologist against the sample logging sheet. Standards are inserted at a rate of one

in twenty prior to bagging and blank material is inserted after mineralised samples (at a rate of about

1 in 40). The dispatch of samples is tracked on a whiteboard at the core shed. Samples are packed

into polyweave bags and sealed with numbered security tags before dispatch from the exploration

camp. The samples are driven by company employees to Southern Arc‟s Mataram logistics base for

shipping to the PT Intertek Utama Services (Intertek) laboratory in Sumbawa Besar for assay. A

report on sample condition, along with a note of any inconsistencies, is emailed by Intertek to the

company upon arrival of the sample at the laboratory.

Core trays from the entire exploration program are stored in a locked rattan, timber and thatch shed

at the exploration base. The shed is well organized and tidy, and the core trays are clearly marked

and stored in a logical order.

Excess sample pulp from the sample preparation (approximately 10 kg for each sample) is stored in

plastic bags at the Intertek sample preparation facility at Sumbawa Besar. Excess pulp from the

packet submitted to the Jakarta laboratory is stored onsite in a dedicated warehouse. This contains

material from all of Intertek‟s clients, and the materials are stored in an orderly fashion.

The core is marked for sampling by the logging geologist; the visual assessment of the grade zone is

used to break sample intervals.

The samples are prepared at the Intertek laboratory in the city of Sumbawa Besar, on the island of

Sumbawa, with assaying done at the Jakarta laboratory. The Jakarta laboratory is ISO 17025

accredited and employs a Laboratory Information Management System (LIMS) for sample tracking,

quality control and reporting. Upon arriving at Intertek the samples are treated as follows:

1. The samples are received;

2. The sample numbers are checked against accompanying paperwork; any discrepancies are

communicated to client before any processing begins;

3. The sample delivery form is completed;

4. The samples are weighed on a balance with a maximum capacity of 20 kg ±0.01 kg;

5. The sample weight form is completed;

6. The standards inserted by the client are identified and weighed separately on a small digital

balance to 0.1 g;



7. The samples are loaded on a trolley with blanks (crushed volcanic rock) and dried in an electric

fan forced oven for twelve hours at 105°C; the oven has an electronic temperature control;

8. The samples are crushed in a jaw crusher to ~2mm; the blank material is run through a crusher

after each sample and a compressed air hose is also used to clean the equipment. Each

Southern Arc sample typically takes 10 minutes to crush;

9. The sample tag is retrieved from the calico bag and placed in a numbered Kraft packet;

10. The crushed sample is placed in a numbered clear plastic bag;

11. The entire sample is pulverized in ~2kg batches in LM2 mills; typically each 2kg charge is milled

for 6 minutes. The target P95 is 75μm;

12. A blank wash is milled after each sample;

13. 1 in 20 samples is tested for grind size. 50 g is weighed out and sieved, with the oversize

weighed;

14. The milled sample is rolled 20 times on a mixing bench;

15. The sample is returned to the plastic bag;

16. The sample is split through a 24 slot riffle splitter; a sample split of 200g-250g is required, and

this usually takes about a sixfold splitting;

17. The sample splits are put into numbered Kraft packets and the previously identified standards

are replaced into the sample sequence. These are identified as standards on the packet;

18. The sample splits are packed into cardboard boxes and sent to the Jakarta assay laboratory;

and

19. The remaining pulverized samples are stored at the laboratory.

Gold is analysed by standard fire assay technique. Copper and silver were analysed by Intertek‟s

GAO2 method which consists of digestion of the sample in hydrochloric/perchloric solution

(HCl/HClO4) followed by an atomic absorption spectroscopy (ASS) analysis.

10.3 Specific Gravity Data

Specific gravity data were routinely collected by Southern Arc. All measurements were taken on core

samples using the simple water immersion technique. While this technique is adequate, it is less

than ideal for porous material. SRK recommends that Southern Arc should seal their core samples

with wax prior to carrying out the density measurements to assure that any rock porosity is properly

accounted for.

There are 1,408 bulk density measurements in the assay database provided by Southern Arc; 404

samples were collected from the Mencanggah Prospect, 141 from Pelangan and 863 from the

Selodong area. Of the data provided, only one sample was deemed invalid and removed from the

database prior to resource estimation. Figure 10.1 summarises the basic statistical data of the bulk

density collected.



Figure 10.1: Statistical data for bulk density measurements

10.4 Quality Assurance and Quality Control Programs

Intertek quality control includes repeat assaying, use of blanks and a series of 23 different standard

reference materials (SRMs) for individual elements. Standards are commercially prepared and

purchased from Gannet Holdings Pty Ltd, Geostats and Canmet in Australia. Blanks and samples

are inserted randomly into batches of 50, comprising 45 samples, 1 blank, 2 duplicate pulp samples

and 2 standards. Duplicate samples are selected randomly from the samples submitted and assayed

at the end of the batch, numbered with the same number as that of the original sample. A dedicated

Laboratory Quality Manager analyzes the QA/QC performance of the laboratory, with results

reported to clients on an as-requested basis. Final results are reviewed by expatriate management

who certify that all relevant QA/QC procedures have been followed. Intertek participates in both an

internal and external inter-laboratory round robin assaying exercises.

The company employs a QA/QC program through the systematic use of standards and blanks and

the normal chain of custody measures during sample transport. The company has used up to 29

different commercial standards produced by Geostats Pty Ltd and Gannet Holdings Pty Ltd,

purchased through Intertek Perth. Recommended assay values ± confidence intervals are provided

on standards received. A total of 499 gold standards, 105 copper standards and 381 blanks have

been used in drilling programs. On average, 1 standard has been inserted into the sample stream

every 31 samples and 1 blank inserted on average every 63 samples. Standards are placed

randomly within the sample stream, whilst blanks are inserted non-randomly either within or



immediately below visually-inferred mineralised zones. “Blank” material comprises fresh basaltic-

andesite lava collected from tertiary lava flows at the foot of Mt. Rinjani, with the highest Au result

recorded from this material being 0.04 ppm Au within equipment reading detection error.

10.5 SRK Comments

SRK reviewed the QA/QC data and noticed that few samples fell outside of the acceptable failure

limits. Of the 499 gold standards submitted, SRK noted three standards outside of the acceptable

limits, and at least two of these appear to be mislabeled standards. Three of the 105 copper

standards fell outside of the acceptable limits and should be investigated. SRK is of the opinion that

the sample handling and shipping is in keeping with best industry practices and adequate for this

type of deposit and mineralisation. A review of the blank samples submitted did not reveal any

serious contamination issues with sample preparation.

In the opinion of SRK, the sampling preparation, security and analytical procedures used by

Southern Arc are consistent with generally accepted industry best practices and are therefore

adequate.



11 Data Verification

11.1 Verifications by Southern Arc

Because exploration is still at an early stage, only limited independent verification of analytical

results has been undertaken to date. A total of 195 Selodong drill core pulps previous assayed by

ITS Intertek were submitted to SGS / Indoassay (Balikpapan) for re-assay, by the same methods as

the Intertek assay (fire assay for Au and acid digest/ASS for Cu). Indoassay Balikpapan is part of the

SGS Group which, like ITS Intertek, provides inspection, testing, certification and verification

services worldwide. Similarly, they are ISO accredited and employ relevant LIMS for sample

tracking, quality control and reporting.

Comparison of assay results shows very similar means and medians for the two laboratories for both

elements, although the maxima for Au are very different and the Indoassay Au assays are somewhat

less variable. SRK considers that the results of re-assays are reasonably similar, although some

large differences were noted and those should be addressed by repeating the re-assay program with

additional pulps.

A total of 140 Pelangan drill core pulps previously assayed by ITS Intertek were submitted to

Kalassay Laboratory (KAL) domiciled at 10 Elmsfield Road, Perth, WA 6056, Australia. Kalassay is

part of the Inspectorate Group which, like ITS Intertek, provides inspection, testing, certification and

verification services worldwide. Similarly, they are ISO accredited and employ relevant LIMS for

sample tracking, quality control and reporting.

Comparison of assay results show ITS gold and silver assays are less than corresponding KAL

values by an average of 9% and 19%, respectively. The latter is attributed to differing finishing

methodology for silver analysis (AAS versus ICP-MS methodology), while the former is within

accepted industry tolerances.

11.2 Verifications by SRK

11.2.1 Site visit

SRK carried out two site visits: the first visit was from December 6 to 9, 2011, with the follow up visit

from April 23 to 26, 2013. During the site visit, SRK examined the drill sites and logging and

sampling procedures, examined the geology in the field, and re-logged several drill holes from each

of the prospect areas. Mineralisation and alteration were noted in drill core and SRK observed

several artisanal miners operating in the Bising and Tibu Serai areas during both site visits.

11.2.2 Verifications of analytical quality control data

SRK reviewed the sample database and noted that a wide range of sample lengths exists in the

database from 0.15 m to 3.8 m with the bulk of the samples (68%) being between 0.5 m and 1.5 m in

lengths. SRK recognizes that shorter sample lengths are often necessary in early stage exploration

for epithermal deposits but recommends that Southern Arc try to standardize sample lengths as

much as possible and avoid taking samples longer than 2 m whenever possible.

SRK validated the digital database by checking for inconsistencies in naming conventions, analytical

units, duplicate entries, length, distance values, or sample intervals less than or equal to zero, blank

or zero-value assays, out-of-sequence intervals, intervals or distances greater than the reported drill



hole length, inappropriate collar locations, and missing interval and coordinate fields. A few minor

inconsistencies were noted and corrected by SRK. No other significant validation errors were noted

in the supplied database.

SRK compared the digital assay database provided by Southern Arc against original assay

certificates provided by Intertek and found no significant data entry errors. In all, SRK validated 85%

of the assay database and found no significant errors.

SRK reviewed the QA/QC data and sampling program and found the data and programs to be

acceptable for the purpose of resource estimation.



12 Mineral Processing and Metallurgical Testing There have been no metallurgical samples collected for testing from the West Lombok Property so

far. SRK recommends that samples be collected for basic metallurgical testing during the next phase

of drilling on the property.



13 Mineral Resource Estimates

13.1 Introduction

The Mineral Resource Statement presented herein represents the first mineral resource evaluation

prepared for the West Lombok Project in accordance with the Canadian Securities Administrators‟

National Instrument 43-101.

The mineral resource model prepared by SRK considers 253 core boreholes drilled by Southern Arc

and Newmont during the period of 2007 to 2013. The drilling covers three discreet prospect areas:

85 drill holes cover the Selodong porphyry copper-gold Prospect, 89 holes cover the Pelangan

epithermal gold Prospect and 67 holes cover the Mencanggah epithermal gold Prospect. Of these,

99 drill holes intersected the mineralised zones considered for resource estimation; 36 drill holes

totalling 5,787 m were included in the Raja resource model, 22 drill holes totalling 3,830 m were

included in the Bising model, 10 holes totalling 1,370 m were included in the Tibu Serai model and

31 holes totalling 11,012 m were included in the Selodong model. The resource estimation work was

completed by Dr. Gilles Arseneau, P.Geo (APEGBC) an appropriate “independent qualified person”

as this term is defined in National Instrument 43-101. The effective date of the resource statement is

July 13, 2013.

This section describes the resource estimation methodology and summarises the key assumptions

considered by SRK. In the opinion of SRK, the resource evaluation reported herein is a reasonable

representation of the global copper and gold mineral resources found in the West Lombok Project at

the current level of sampling. The mineral resources have been estimated in conformity with

generally accepted CIM “Estimation of Mineral Resource and Mineral Reserves Best Practices”

guidelines and are reported in accordance with the Canadian Securities Administrators‟ National

Instrument 43-101. Mineral resources are not mineral reserves and do not have demonstrated

economic viability. There is no certainty that all or any part of the mineral resource will be converted

into mineral reserve.

The database used to estimate the West Lombok Project mineral resources was audited by SRK.

SRK is of the opinion that the current drilling information is sufficiently reliable to interpret with

confidence the boundaries for epithermal gold and porphyry copper mineralisation and that the

assay data are sufficiently reliable to support mineral resource estimation.

Gemcom GEMSTM

Version 6.5 was used to construct the geological solids, prepare assay data for

geostatistical analysis, construct the block model, estimate metal grades and tabulate mineral

resources. The Geostatistical Software SAGE2001TM

was used for geostatistical analysis and

variography.

13.2 Resource Estimation Procedures

The resource evaluation methodology involved the following procedures:

Database compilation and verification;

Construction of wireframe models for the boundaries of the vein-hosted gold and porphyry

copper mineralisation;

Definition of resource domains;



Data conditioning (compositing and capping) for geostatistical analysis and variography;

Block modelling and grade interpolation;

Resource classification and validation;

Assessment of “reasonable prospects for economic extraction” and selection of appropriate cut-

off grades; and

Preparation of the Mineral Resource Statement.

13.3 Resource Database

The drill hole database used to estimate the mineral resources presented in this report contains 241

drill holes including 53,252 m of core. The drill hole database contains descriptive information and

assay grades from exploration drilling carried out by Southern Arc and Newmont. The database was

provided to SRK as an ACCESS database that includes the following tables:

Drill hole collar information such as location and length;

Down hole survey information such as direction and dip;

Lithology information including rock group codes and interpreted geology;

Mineralisation information including mineral types;

Geotechnical data, RQD and recovery data;

Vein counts and types of veins;

Alteration information including alteration type;

Down hole magnetic susceptibility data;

Down hole specific gravity measurements; and

Chemical analytical (assay) records.

The supplied mineral resource database was imported into Gemcom‟s GEMSTM

6.5 software and

validated by checking for inconsistencies in naming conventions, analytical units, duplicate entries,

length, distance values, sample intervals less than or equal to zero, blank or zero-value assays, out-

of-sequence intervals, intervals or distances greater than the reported drill hole length, inappropriate

collar locations, and missing interval and coordinate fields. A few minor inconsistencies were noted

and corrected by SRK. No other significant validation errors were noted in the supplied database.

13.4 Solid Body Modelling

Solid models were created to provide spatial limits for each of the mineralisation domains within the

West Lombok deposits. Separate geological models were generated for each of the prospect areas

estimated. Domains were created by interpretation of the drill hole lithology and assay data from the

drill holes.

13.4.1 Raja Deposit – Pelangan Prospect

The gold mineralisation at the Raja Deposit is generally associated with quartz veins within wider

quartz breccia zones. The gold is associated with a high sulphidation epithermal quartz vein system.

Two parallel vertical veins have been identified within the Raja Deposit area. The veins have been

explored by drilling over a strike length of 1,000 m and to a vertical depth of 250 m (Figure 13.1).



Wireframes were constructed on 20 m spaced sections using a 1.5 m minimum horizontal thickness

and a 0.15 g/t nominal cut off. A digital model of the topography was also generated and the vein

wireframes were clipped against the digital surface topographic model. No surface was generated for

overburden, but little or no overburden occurs over the vein areas.

Note: Grid is 200 by 200 m

Figure 13.1: Planveiw of Raja wireframes

13.4.2 Bising and Tibu Serai Deposits – Mencanggah Prospect

The gold mineralisation at Bising and Tibu Serai is generally associated with quartz breccia zones.

The gold is associated with a high sulphidation epithermal quartz vein system. Two parallel vertical

veins have been identified within the Bising Deposit area and a single high grade vein has been

identified at Tibu Serai so far. The veins have been explored by drilling over a strike length of 700 m

at Bising and 200 m at Tibu Serai (Figure 13.2).

Geological modelling was completed by SRK using Gemcom GEMSTM

version 6.5. Wireframes were

constructed on 20 m spaced sections using a 1.5 m minimum horizontal thickness and a 0.15 g/t

nominal cut off. A wireframe of the topography was also generated and the vein wireframes were



clipped against surface topography. No surface was generated for overburden, but little or no

overburden occurs over the vein area.

Figure 13.2: Planview of Bising and Tibu Serai wireframes (Note: Grid is 500 by 500 m)

13.4.3 Selodong Deposit – Selodong Prospect

The copper-gold gold mineralisation at Selodong is associated with structural zones within altered

diorite. Two main porphyry zones have been identified by drilling and extend for about 1,500 m in a

north-south direction (Figure 13.3).

Geological modelling was completed by SRK using Gemcom GEMSTM

version 6.5. Wireframes were

constructed on 50 m spaced sections using a 0.2 g/t copper equivalent. A wireframe of the

topography was also generated and the vein wireframes were clipped against surface topography.

No surface was generated for overburden, but little or no overburden occurs over the vein area.



Figure 13.3: Planview of Selodong wireframes (Note: Grid is 500 by 500 m)

13.5 Compositing

All assay data were composited to a fixed length prior to estimation. SRK evaluated the assay

lengths for each of the resource areas and selected the most appropriate composite length for each

area.


An evaluation of sample lengths indicated that 92% of assay lengths within the mineralised zones

were 1 m or less (Table 13.1). For this reason, SRK decided to composite the assay data to a fixed

1 m length within the wireframes starting from the drill hole collars. Any composites that were less

than 0.5 m in length after the compositing routine were added to the previous interval to assure that

no composites were less than 0.5 m or greater than 1.5 m.

13.6 Evaluation of Outliers

Grade capping analysis was conducted on the domain-coded sample assay data in order to limit the

influence of extreme assay values during estimation.

Block grade estimates may be unduly affected by high grade outliers. Therefore, assay data were

evaluated for high grade outliers and capping was determined from decile and probability plot

analyses.


Because of the high variation in raw assay lengths from 0.2 m to 1.5 m, SRK evaluated the assay

average grades of different sample lengths to determine if shorter sample lengths were associated

with high grade sections of the deposits and to evaluate if compositing prior to capping was

appropriate. Some correlation between sample lengths and assay values was apparent, with shorter

sample lengths having higher average grades than longer sample lengths. Based on the analysis,

SRK decided to carry out the capping on 1 m composites, not the assay data. Table 13.4

summarises the capping data for the Raja Deposit.

*Lost metal is (Average - Averaged Capped)/Average*100 where Average is the average grade of the assays before capping and Average Capped is the average grade of the assays after capping.

13.6.2 Bising and Tibu Serai deposits – Mencanggah Prospect

SRK evaluated the assay data for the Bising and Tibu Serai Deposits to determine if capping was

required. Capping analysis was carried out on 1.5 m composites and the capping level was set at

5 g/t gold based on the change of slope on a cumulative probability plot (Figure 13.4).




SRK evaluated the gold assay data for the Selodong Deposit to determine if capping was required.

Because of the longer composite length of 3 m used for Selodong and because of the lack of

apparent higher average grade associated with shorter composites (Table 13.3), SRK decided to

cap the gold assay data prior to compositing to 3 m lengths. Capping levels were set to 4 g/t. SRK

decided that copper did not require capping as no significant grade outliers seemed to exist for

copper.

13.7 Statistical Analysis and Variography


A basic statistical analysis was carried out on assay and composited data. A summary of the

samples located within the mineralised envelope is presented in Table 13.5.

Because of the narrow nature of the mineralised domain at Raja, experimental correlograms and

models could not be generated from the existing data set. A simple omni directional exponential

variogram was designed from the grade times thickness (GT) data using Sage2001TM

software.

Spatial continuity of gold and copper was evaluated with correlograms developed using SAGE

2001 TM

version 1.08. The correlogram measures the correlation between data values as functions of

their separation distance and direction. The distance at which the correlogram is close to zero is

called the “range of correlation” or simply the range. The range of the correlogram corresponds

roughly to the more qualitative notion of the “range of influence” of a sample or composite.

Variographic analysis was completed for gold for the Raja, Bising, Tibu Serai and Selodong Deposits

and for copper for the Selodong Deposit. Directional correlograms were generated for composited

data at 30 degree increments along horizontal azimuths. For each azimuth, correlograms were

calculated at dips of 0, 30 and 60 degrees. A vertical correlogram was also calculated. Using

information from these 37 correlograms, Sage determines the best fit model using least square fit

method. The correlogram model is described by the nugget (Co), two nested structure variance

contributions (C1, C2), ranges of the variance contributions and the model type (spherical or

exponential). After fitting the variance parameters, the algorithm then fits an ellipsoid to the 37

ranges from the directional models for each structure. The final models of anisotropy are given by

the lengths and orientations of the axes of the ellipsoids.

Correlograms were developed on composited assay data except for the Raja Deposit where

correlograms were developed on grade times thickness (GT) because of the narrow nature of the

mineralisation at Raja. Table 13.8 summarises the correlogram parameters used for each of the

deposit areas estimated.

13.8 Block Model and Grade Estimation

Mineral resources for the West Lombok Project were estimated in three separate block models; one

representing each of the main prospect areas (Figure 13.5).

Block modelling was carried out in Gemcom GEMSTM

6.5 software by Dr. Gilles Arseneau, Associate

Consultant with SRK.

Block estimates were carried out in 10 x 10 x 5 m blocks for the Raja, Bising and Tibu Serai Deposits

and a 10 x 10 x 10 m for the Selodong Deposit. A percent model was used to weight partial blocks

situated at zone boundaries. Block model parameters are defined in Table 13.9.

13.8.1 Grade models

Grades were estimated by Ordinary Kriging with a minimum of two samples for Raja, four samples

for Selodong and five samples for Bising –Tibu Serai deposits. To estimate block grades a maximum

of twelve composites were used in the Raja and Bising –Tibu Serai deposits and a maximum of nin

to twelve composites were used in the Selodong Deposit. Grade interpolations were carried out in

three passes, with each successive pass using a larger search radius than the preceding pass and

only estimating the blocks that had not been interpolated by the previous pass. Table 13.10

summarises the search parameters for each interpolation pass.

13.8.2 Bulk density model

There are 1,408 bulk density measurements in the West Lombok database with an average of 2.58.

SRK is of the opinion that while these are sufficient to estimate a mineral resource, the amount of

bulk density data is too limited for estimation by kriging. For this reason, SRK used a simple average

to estimate the model block densities. Bulk density data used for the resource estimate is

summarised in Table 13.11.

13.9 Model Validation and Sensitivity

13.9.1 Validation of Raja model

The Raja block model was validated by comparing the interpolated block grades against the

composited cap grades on section and plan views (Figure 13.6). Overall, the comparison showed

that the estimated blocks agreed reasonably well with the composite grades from which they were

derived.

Figure 13.6: Comparison of block grades and composite grades, block model Level 58 (110 m above

sea level) (Note: Grid is 200 x 200 m)



Additional validation of the Raja model was provided by re-estimating the mineral resources using

inverse distance squared (ID2) estimation. The ID

2 estimation was carried out using the same search

criteria as for the Ordinary Kriging run, but 1 m composited gold assays were used directly to

estimate gold grades instead of using grade times thickness. The two estimation procedures

returned very similar results. The Ordinary Kriging model returned slightly more tonnes at a lower

grade than the ID2 model, but the two models contained similar metal content (Figure 13.7).

Figure 13.7: Metal content of Ordinary Kriged and Inverse Distance Squared models at various grade

cut-offs

13.9.2 Validation of Bising – Tibu Serai model

The Bising and Tibu Serai block model was validated by comparing the interpolated block grades

against the composited cap grades on section and plan views (Figure 13.8). Overall, the comparison

showed that the estimated blocks agreed reasonably well with the composite grades from which they

were derived.

Figure 13.8: Plan view of Bising Deposit comparing block and composite gold grades, block model

Level 25 (345 m above sea level) (Note: Grid is 200 x 200 m)

Additional validation of the Bising and Tibu Serai model was carried out by comparing well informed

blocks with composites contained within those blocks, and comparison of average assay grades with

average block estimates along different directions – swath plots.

Figure 13.9(a) shows a comparison of estimated gold block grades, with borehole composite assay

data contained within those blocks, within the mineralised domains for the Bising deposit.

Figure 13.9(b) shows the same for the Tibu Serai deposit. On average, the estimated blocks are

similar to the composite data, although there is a large scatter of points around the x = y line. This

scatter is typical of smoothed block estimates compared to the more variable assay data used to

estimate those blocks. The thick white line that runs through the middle of the cloud is the result of a

piece-wise linear regression smoother. Comparison for Tibu Serai is very limited because of the

small size of the deposit and available data.

As a final check, average composite grades and average block estimates were compared along

different directions. This involved calculating de-clustered average composite grades and

comparison with average block estimates along east-west, north-south, and horizontal swaths.

Figure 13.10 shows the swath plots in the mineralised zone at Bising and Figure 13.11 shows the

swatch plot for the mineralised zone at Tibu Serai. The average composite grades and the average

estimated block grades are quite similar in all directions. The composite data display slightly more

variability than the block grades as a result of the smoothing effect due to the Ordinary Kriging

estimation. Overall, the validation shows that the current resource estimate is a good reflection of

drill hole composited data. Comparison of the Tibu Serai data is of limited use because of the small

data set used to prepare the block model.

13.9.3 Validation of Selodong Model

The Selodong block model was validated by comparing the interpolated block grades against the

composited cap grades on section and plan views (Figure 13.12). Overall, the comparison showed

that the estimated blocks agreed reasonably well with the composite grades from which they were

derived.



Figure 13.12: Plan view of Selodong model comparing copper equivalent block grades and corresponding composite grades, block model Level 22 (25 m above sea level)( Note: Grid is 200 x 200 m)

Additional validation of the Selodong model was carried out by comparing well informed blocks with

composites contained within those blocks, and comparison of average assay grades with average

block estimates along different directions – swath plots.

Figure 13.13 shows a comparison of estimated gold block grades with borehole composite assay

data contained within those blocks in all mineralised domains of the Selodong deposit. Figure 13.14

shows the same for copper. On average, the estimated blocks are similar to the composite data,

although there is a large scatter of points around the x = y line. This scatter is typical of smoothed

block estimates compared to the more variable assay data used to estimate those blocks. The thick

white line that runs through the middle of the cloud is the result of a piece-wise linear regression

smoother.

As a final check, average composite grades and average block estimates were compared along

different directions. This involved calculating de-clustered average composite grades and

comparison with average block estimates along east-west, north-south, and horizontal swaths.

grades are quite similar in all directions. The composite data display slightly more variability than the

block grades as a result of the smoothing effect due to the Ordinary Kriging estimation. Overall, the

validation shows that current resource estimate is a good reflection of drill hole composited data.

13.10 Mineral Resource Classification

Block model quantities and grade estimates for the West Lombok Project were classified according

to the CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005) by

Dr. Gilles Arseneau, P.Geo. (APEGBC); an appropriate independent qualified person for the

purposes of National Instrument 43-101.

Mineral resource classification is typically a subjective concept. Industry best practices suggest that

resource classification should consider both the confidence in the geological continuity of the

mineralised structures, the quality and quantity of exploration data supporting the estimates, and the

geostatistical confidence in the tonnage and grade estimates. Appropriate classification criteria

should aim at integrating both concepts to delineate regular areas at similar resource classification.

SRK is satisfied that the geological modelling honours the current geological information and

knowledge. The location of the samples and the assay data are sufficiently reliable to support

resource evaluation. The sampling information was acquired primarily by core drilling on sections

spaced between 25 and 50 metres depending on the deposit modelled.

Generally, for mineralisation exhibiting good geological continuity, and investigated at adequate drill

hole spacing with reliable assay data, SRK considers that blocks estimated during the first estimation

run can be classified in the Indicated category within the meaning of the CIM Definition Standards for

Mineral Resources and Mineral Reserves. However, SRK is of the opinion that the mineralisation at



the West Lombok Project is best classified as Inferred Mineral Resource because of the widely

spaced drilling and relatively poor grade continuity at the current drill spacing.

SRK is of the opinion that the confidence in the estimate is insufficient to allow for the meaningful

application of technical and economic parameters or to enable an evaluation of economic viability.

13.11 Mineral Resource Statement

CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005) defines a

mineral resource as:

“(A) concentration or occurrence of diamonds, natural solid inorganic material, or natural solid

fossilized organic material including base and precious metals, coal, and industrial minerals in or on

the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable

prospects for economic extraction. The location, quantity, grade, geological characteristics and

continuity of a Mineral Resource are known, estimated or interpreted from specific geological

evidence and knowledge”.

The “reasonable prospects for economic extraction” requirement generally implies that the quantity

and grade estimates meet certain economic thresholds and that the mineral resources are reported

at an appropriate cut-off grade, taking into account extraction scenarios and processing recoveries.

In order to meet this requirement, SRK considers that major portions of the deposits on the West

Lombok Project may be amenable for open pit extraction. In order to determine the quantities of

material offering “reasonable prospects for economic extraction” by an open pit, SRK used a pit

optimizer and reasonable mining assumptions to evaluate the proportions of the block model

(Inferred blocks) that could be “reasonably expected” to be mined from an open pit.

Open pit parameters were selected based on experience and benchmarking against similar projects

(Table 13.12). The reader is cautioned that the results from the pit optimization are used solely for

the purpose of testing the “reasonable prospects for economic extraction” by an open pit and do not

represent an attempt to estimate mineral reserves. There are no mineral reserves on the West

Lombok Project. The results are used as a guide to assist in the preparation of a mineral resource

statement and to select an appropriate resource reporting cut-off grade.

SRK considers that the blocks located within the conceptual pit envelope satisfy the “reasonable

prospects for economic extraction” and can be reported as a mineral resource. Tables 13.13 to

Table 13.16 summarise the mineral resources for the West Lombok Project.

13.12 Grade Sensitivity Analysis

The mineral resources of the West Lombok Project are very sensitive to the selection of the reporting

cut-off grade. This is especially true in the Bising deposit. To illustrate this sensitivity, the global

model quantities and grade estimates are presented in Tables 13.18 to Table 13.21 at different cut-

off grades. The reader is cautioned that the figures presented in this table should not be

misconstrued with a Mineral Resource Statement. The figures are only presented to show the

sensitivity of the block model estimates to the selection of cut-off grade. Figures 13.17 to Figure

13.20 present this sensitivity as grade tonnage curves. The steep decline in tonnage with increasing

cut-off grade is indicative of the high susceptibility of the deposit to cut-off selection.

14 Adjacent Properties This section is taken from Campbell, 2010. The author of the report has been unable to verify the

information contained in this section and the information presented in this section of the report is not

necessarily indicative of the mineralisation on the West Lombok Project that is the subject of this

technical report.

Adjoining the western property boundary is a 5,000 hectare concession held by PT. Bintang

Sumberdaya under a IUP exploration license. Field inspections in this locality reported intense

porphyry style alteration over a width of 50+ m, with at least 850 m of strike length. Secondary

copper oxides (malachite, azurite and lesser chrysocolla) are prolific in the western part of the area

and are currently being mined by local artesian miners. Host rocks comprise magnetite-epidote-

silicic altered diorite porphyry intrusives, with some later phyllic overprinting. Strong northwest

structural control of mineralisation is evidenced by intense fracturing, fault slickensides and sharp

contact boundaries on porphyry stockwork veining. Overlying and peripheral to the stockwork zone

are intermixed argillic and advanced argillic assemblages, hosting limited or no stockworking.

A single grab sample of porphyry veining material being mined by local artesian miners assayed

0.62 g/t Au and 0.36% Cu.



15 Other Relevant Data and Information There is no other relevant data available about the West Lombok Project.



16 Interpretation and Conclusions

The West Lombok Property hosts an early stage copper gold project situated on the west side of

Lombok Island in Indonesia and covering a northwest trending 13 km by 7 km wide mineralised

structural corridor.

Mineralisation on the property has been separated into three main prospect areas: from north to

south, the Pelangan, the Mencanggah and the Selodong Prospects. Each prospect consists of

several mineral targets or showings; many of which have been the subject of exploration by diamond

drilling that host both porphyry copper-gold and epithermal gold mineralisation.

Work carried out by Southern Arc has included geophysical and geochemical surveys as well as

geological mapping and diamond drilling. In total, Southern Arc has drilled 201 holes totalling

47,750 m. The drilling programs resulted in the identification of inferred mineral resources for the

Raja, Bising, Tibu Serai and Selodong Deposits as presented in Section 13 of this report.

The mineral resources at West Lombok have been classified as Inferred Mineral Resources by SRK.

An Inferred Mineral Resource has the lowest level of confidence as defined by CIM (Figure 16.1).

For this reason, a certain risk is associated with the tonnage and grade estimates presented in this

report. Additional drilling is required to upgrade the mineral resource class from Inferred to Indicated

or Measured.

Readers are cautioned that there are no guarantees that additional drilling will result in additional

mineralisation being defined or that the classification will improve if the drilling is not successful in

better defining the geological knowledge of the deposits. Furthermore, additional drilling may change

the geological interpretation of the deposit which could result in a reduction or increase in the deposit

size.

SRK is not aware of any other significant risks and uncertainties that could be expected to affect the

reliability or confidence in the early stage exploration information discussed herein.

Figure 16.1: Classification of mineral resources and mineral reserves



All deposits identified so far are still open at depth and along strike and further drilling could discover

additional mineralisation, especially at Raja where the possibility of finding mineralisation that could

be amenable to underground mining seems very good.

The West Lombok Property contains several other mineral occurrences and only a small portion of

the favourable ground has been drill tested to date. SRK is of the opinion that the untested mineral

occurrences represent a significant opportunity to locate additional mineralisation.



17 Recommendations SRK recommends that Southern Arc continue to explore the West Lombok Property. SRK

recommends a two phase exploration program (Phase 3A and Phase 3B) including 4,010 m of

drilling at Raja and Bising. Phase 3B is contingent on receiving positive results from phase 3A of

exploration.

17.1 Pelangan

SRK recommends that Southern Arc drills an additional eight holes for 1,420 m in the Raja Deposit

as part of the next exploration phase (Phase 3A) (Table 17.1). The drilling is targeted to infill around

previously identified higher grade mineralised shoots and to test the down dip extension of the

mineralised zone and, if results are positive, upgrade the mineral resources from inferred to

indicated (Figure 17.1). If the results of the first drilling phase are encouraging, SRK recommends an

additional five drill holes (Phase 3B) for the Raja Deposit to evaluate the down dip potential of the

mineralisation.

17.2 Mencanggah

SRK recommends an additional eight drill holes for the Bising deposit (Phase 3A) to help upgrade

the resource classification from inferred to Indicated. The drill holes are mainly designed to infill

between existing drill holes to help confirm the continuity of grades between drill holes within the

mineralised unit (Table 17.2).

Total Phase 1 = 1,385 3

No additional drilling is recommended at this stage for the Selodong Deposit. SRK recommends that

Southern Arc continues geological mapping in the Tibu Serai and Selodong areas and that drill core

samples be taken from the Raja and Bising deposits for preliminary metallurgical testing and

characterization. Approximately 4,000 m of exploration drilling is recommended to test other undrilled

targets at Mencanggah including Tibu Serai, Mahoni and several other localities with highly

anomalous surface geochemistry. Drill testing is also recommended for the Lala structure on the

Palagan Prospect area where highly anomalous surface values are located 350 m east of Raja along

an 800 m parallel trend.
