ELR94 is a granted lease within the Redbank Copper operational area in the Northern Territory, and currently is in its twenty third year of tenure. During the reporting period, the company completed a small RC drilling programme across Charlie prospect within the lease, successfully intersecting copper mineralisation. Proposed drilling of Double Bluff and Quartzite prospects was curtailed due to late drilling start and adverse weather. The purpose of the 2011 RC drilling was to identify any sulphide mineralisation beneath previously identified copper oxide ore, and to add to the copper metal inventory within ERL 94.

1.0 BACKGROUND - REDBANK COPPER OPERATIONS
The Redbank Copper Mine is located in the north‐east of the Northern Territory a pproximately 30 km from the Queensland border and 70 km from the coast of the Gulf of Carpentaria. It strad dles the Savannah Way which connects the townships of Borroloola in the Northern Territory and Burketown in Que ensland. It is around 1,200 km south east of Darwin by sealed and unsealed road.

The Redbank Copper field was discovered in 1916 and small scale mining was carriied out until the early 1960’s. Subsequently exploration was carried out during the late 1960’s through to the 1990’s by various groups, culminating in larger scale mining operations being undertaken in the mid 1990’s when the Sandy Flat open pit was developed to supply oxide/sulphide ore to a 250,000 tpa flotation plant built on site. Some very hig h grade (>25% copper) ore was also direct shipped at this time. The operation ceased after less than 2 years because of declining copper prices. With the exception of the mill, the flotation plant and crushing circuit remain on site. Both a re in reasonable condition and are planned to be refurbished to operating condition with a redevelopment of the Proj ect.
The most recent processing was a copper leaching operation that began producing o n an intermittent basis in 2004 and utilised oxide ore that had been stockpiled during the previous mining. The curr ent owners have operated the site since 2005 and some of the remaining ore stockpiles from the previous mining ve nture in the 1990’s have been processed.
In 2009, with new funding and management arrangements, Redbank undertook the fol lowing:
• Placed the site on care and maintenance and embarked on a program to impr ove environmental compliance, in particular to remedy discharges of contaminated water from the site.
• Carried out a review of the project to determine the future direction of its development, and generate a mine study outlining the path to redevelopment.
• Embarked on a well‐funded exploration program that aims to discover new resources and to upgrade the status of the existing resources.
The study undertaken by Redbank examined options for future development of the p roject. Redbank identified that the future of the project is primarily in processing sulphide copper ores, which co mprise more than 86% of the current resources, to make quality copper concentrates. In addition copper cathode can be made from the oxide ores. Further work is required to establish additional resources and better define operating parameters. In May 2011 the total resource was estimated by SRK Consultants as 6,268,000 tonnes at a gra de of 1.53% copper containing 96,500 tonnes of copper metal.
Figure 2: Redbank Infrastructure on ELR94, July 2011
The operational area consists of an Exploration Retention License (ELR94) and seven Mineral Leases (ML631, ML632, ML633, ML634, ML635, ML636 and ML1108) contained within the ELR. The comp any has recently applied for a Mining Lease (MLA27385) to replace ELR94 ahead of a decision to mine in 2012. Red bank Mine Operations Pty Ltd, the holder of ELR94, also has a number of exploration interests within the vicinity of the existing Redbank Mine site (EL24654, EL26758, EL26778, EL26779, EL26780, EL26781, EL26965, EL26999, EL2724 0, EL27241, EL27329, EL27737, ELA28003, EL28288, EL28289, EL28290 and ELA28024). In addition the company has r ecently applied for a tenement contiguous with the land holding over the Queensland border, EPMA18553. These a re located mostly to the north and west of the mine site as shown below in Figure 3.
2.0 REGIONAL GEOLOGICAL SETTING
Regionally the Redbank copper deposits lie within the Proterozoic sequences of th e MacArthur River Basin (see Figure 1). The basin hosts a number of world class base metal deposits. The Redbank c opper mineralisation is hosted by the Lower Proterozoic Gold Creek Volcanics, a sequence of predominantly interm ediate sub volcanic intrusions, extrusions, breccia pipes, and intercalated sediments. The copper mineralisation identified to date has been principally interpreted as being contained in volcanic breccia pipes, of which 30 to 50 have been recognised by various explorers. Only a minority of the breccia pipes are mineralised and only som e of those contain potentially economic concentrations of copper.
The Packsaddle Microgranites locally intrude the Gold Creek Volcanics and are presen t close to the known Redbank copper deposits. Gold Creek Volcanics are present in a significant portion of the region al tenements. Further east the Gold Creek Volcanics are obscured beneath surficial Cainozoic sequences. The Hob blechain Rhyolite, a member of the Masterton Formation overlies the Gold Creek volcanics to the west.

Figure 3: Location of ELR94 and Tenement Holding of Redbank Copper Limited 3.0 TENEMENT GEOLOGY
The Redbank Mining Centre contains 23 breccia “pipes” or diatremes and shear zon es/veins most of which contain copper mineralization. These structures are mainly hosted by the Hobblechain Rhy olite, the Gold Creek Volcanics and the Wollogorang Formation; however, diatremes have also been recorded in the S ettlement Creek Volcanics and the Seigal Volcanics. Host rocks are brecciated and altered passing out into less alter ed shallow‐dipping host rocks. The volcanic breccias from the Redbank Mining centre appear to be located with in an east‐trending structural corridor although mineralized breccia veins are aligned north‐east with a steep nort herly plunge to the shoots. A conjugate fault system with dextral movement would tend to produce dilation zones alligned along an easterly trend.
The localizing structures are probably faults or fault intersections plunging thro ugh the Tawallah Group into basement containing granite. The copper deposits occur in clusters, exceed 300 m in d epth and have near circular to irregular outlines from 50 m to 150 m across.
Primary mineralization consists of disseminations and veins with chalcopyrite and bornite in breccia. Gangue minerals are dolomite, barite, chlorite, potassium‐feldspar, quartz, pyrite, hematite, a patite and pyrobitumen. Clasts of overlying units are evidence for collapse during breccia formation. In the oxide zo ne from surface to 30 m depth, grades approach 6% copper, the main minerals being malachite, azurite, chalcocite an d chrysocolla.
Breccia and wall rocks are associated with intense potassic alteration consisting off carbonate‐chlorite‐potassium feldspar‐quartz, pyrite, hematite and pyrobitumen.
Past production was 19 600 tonnes grading 5% copper and currently indicated resour ces from two deposits are 2.0 million tonnes grading 1.66% copper at Bluff, and 1.5 million tonnes grading 2% copper at Sandy Flat.
The presence of pyrobitumen of organic origin precludes a purely volcanic origin for the breccia and may support a low pressure, low temperature epithermal source. Several theories have been advanced to explain the origin of the diatremes which are produced by over‐pressured fluids. There is no direct evidence for magmatic fluids and the fluids might be produced by mixing of sulphate and copper‐rich basinal brines, derived from above and lateral to the deposits, with rising, reduced, hydrocarbon‐bearing fluid sourced in the underlying Wollogorang Formation. The significance of a conceptual model based on the mixing of reduced and oxidized fluids is that it increases the potential of the area for more extensive copper deposits in a structural setting that permits oxidized brines to mix with reduced fluids from other formations in the Tawallah Group.
4.0 EXPLORATION MODELS
The consensus of most of the modern era (post‐1970) explorers in the Redbank area is that the mineralisation is contained in the approximately circular volcanic breccia pipes as the result of fluid circulation in the breccia. The breccia pipes development has also been interpreted as involving largely autochthonous brecciation of the trachyandesite host rock, with little displacement.
There have been some suggestion that there has been post volcanic slumping in some pipes causing minor (<10m) vertical displacement of sediments overlying the Gold Creek volcanics into the pipes. Minor normal faults and jointing have been interpreted as exerting a control on the location and form of the pipes. A peculiarity of the more comprehensively mineralised pipes is the association of the mineralisation with pyrobitumen. The origin of the pyrobitumen has been variously speculated as resulting from intense reduction of carbonate to a high temperature derivative of an organic precursor.
RC and diamond core drilling by Redbank on deposits in the area during 2006 to 2009, has indicated that the mineralisation does not display all the characteristics that could be expected solely from the circulation of mineralised fluids through the prepared breccia pathways. While there are clearly veins of sulphidic copper mineralisation contained within the breccia they are typically fragmented. Also much of the primary mineralisation consists of chalcopyrite and chalcocite grains disseminated through the host trachyandesite. The oxide mineralisation retains the characteristics of the primary mineralisation structures and fabrics with cuprite largely replacing the disseminated chalcocite and chalcopyrite, with a minor amount of azurite and malachite vein formation following ground water migration along open weathering fractures.
More detailed studies of petrogenesis and ore formation are planned but the initial indications are that there may be a precursor disseminated style of mineralisation emplaced in the breccia pipes. The source of the precursor mineralisation could represent a major target for large scale disseminated copper mineralisation. As a corollary exploration should not only focus on finding mineralised breccia pipes but should also be trying to discover the source of the precursor disseminated mineralisation which has the potential to be a much larger target.
Conceptually, the possibility exists for ‘Manto’ style stratabound deposits forming at depth below the limit of breccia formation, as a primary mineralisation focus over structural décollements from fluid travelling laterally from major through‐going lineaments, such as the Calvert Hills fault to the south west of the ELR94.
Packsaddle Microgranite (or rhyolitic) intrusions occur in close association with the Redbank copper Mineralisation. It is not yet apparent if there is any paragenetic significance in this spatial association. The Packsaddle Microgranites have interpreted as associated with a regional 1,725Ma felsic intrusive event in the Macarthur River Basin (Page et al, 2000).
5.0 PREVIOUS EXPLORATION ON REGIONAL TENEMENTS
Review of the available historic data for the region indicated that it was disjointed and compilation into a modern GIS system was required. Principal explorers were Carpentaria, Rio Tinto, and then later CRA, mainly exploring for base metals, uranium and diamonds in the general area. Several generations of work starting in the 1960’s can be grouped according to commodity as follows:
(i) 1956 to 1960 – predominantly uranium exploration, (ii) 1965 to 1971 – mainly uranium plus focus on copper, particularly at Redbank, (iii) 1978 to present – uranium, diamonds, gold and base metal, manganese and industrial minerals
(phosphates)
Previous exploration on ELR94 has focussed on copper mineralisation analogous to the historical workings at Redbank and Azurite. This has been comprehensively summarised in Redbank Mines (2005) containing a report prepared by the independent geologists SRK Consulting Pty Ltd. The SRK conclusions on previous exploration and the exploration potential of ELR94 are summarised below.
Previous exploration at Redbank has been sporadic, with a concentration on the known style of relatively small but high grade breccia pipes. Potential targets were identified by the NEWAIM programme in 1971 by assuming the breccia pipes had a surface expression of shallow depressions; the only significant discovery since then was Punchbowl, identified by a similar criterion as the NEWAIM discoveries.
Soil sampling over ELR94 has been carried out in a piecemeal fashion over restricted areas. This data shows that the resources such as Bluff and targets such as Quartzite and Roman Nose are defined by about 120ppm Cu in soil samples; using this criterion, five soil anomalies have been identified that lack any drilling. These are prospective for further breccia pipe style mineralisation.
Analysis of the more recent magnetic data acquired by CRAE allows an interpretation of the underlying structural framework of ELR94. The ESE‐WNW trending structures that host the breccia pipes (Redbank and Masterton Trends) are clearly visible; additionally, a possible parallel structure that hosts Sandy Flat and numerous NNE‐SSW trending structures are evident. The intersection of the ESE‐WNW and NNE‐SSW trending structure may control the location of the breccia pipes.
In the immediate area of the Redbank mine, these structures are expressed by the drainage patterns. An interpretation of the underlying magnetic data and the drainage highlights 10 targets that are currently unexplored, two of which are on ELR94. The poor resolution of the magnetic data for the western half of ELR94 precludes the identification of further magnetic trends except by assuming the correlation between drainage patterns and the underlying geological structure.
Basin‐wide strata with elevated copper levels in the Wollogorang Formation have been noted by Plumb et al. (1990), as well as anomalous copper in the underlying Siegel Volcanics. There is potential that there may be economic concentrations in large tonnage, low grade stratabound orebodies, although previous exploration programmes have not investigated this.
In 2008 a soil geochemistry program was undertaken to complete coverage of the tenement on a nominal 100 by 50m pattern. A total of 1,702 samples were collected and analysed for a suite of elements including copper. Old workings at Redbank, Azurite and Prince were clearly expressed with copper in excess of 500ppm, and likely enhanced by dust dispersion from the old mining activities. The Bluff deposit was also prominent because of mineralisation exposed at the surface. The soil geochemistry for the Sandy Flat deposit was collected before the deposit was identified and mined, and is identifiable by a number of peak soil values of between 300 and 400ppm copper.
Background levels of copper in the host rocks were less than 75ppm, and above 200ppm is considered to be a
significant anomaly. A series of 5 soil geochemistry anomalies numbered An1 to 5 in were previously defined by CRAE (CRA Ltd) in 1995, and the 2008 program defined a further 16 anomalies of equivalent or higher rank (Figure 4 ‐ An6 to An21). The 21 copper soil anomalies thus defined do not necessarily represent copper mineralised breccia pipes, but a number clearly have values and dimensions that are consistent with the known pipe signatures.
Commencing in April 2009, a comprehensive exploration effort was commenced by Redbank, including:
• compilation to digital formats of all historic media, • validation of all drill data, including data entry of geology • confirmatory field mapping • establish AHD survey control over the lease • capture of high resolution orthophoto and generation of DTM • close‐spaced small loop TEM survey of Redbank‐Bluff corridor • complete coverage of lease with gravity survey at minimum 200 x 200m, with infill • partial coverage of the lease with close‐spaced ground magnetics and radiometrics.
In addition, RC Drilling of advanced targets on the ELR commenced in July 2009, with immediate success at the Punchbowl deposit, where ten holes were drilled and significant copper intersections were received, increasing with grade at depth. Significant copper intersections were also delivered at depth from RC drilling of the Quartzite deposit, where five holes were drilled. Three holes were drilled at two bullseye targets generated by the TEM survey near the Prince deposit, but encountered no copper mineralisation. The tenement package included numerous advanced copper targets and has an identified JORC resource of 6.268 million tonnes at a grade of 1.53% copper of which 2.766Mt at 1.55%Cu are Indicated Resources and 3.502Mt at 1.52% Cu are Inferred Resources.

6.0 EXPLORATION FOR THE PERIOD 10th August 2011 TO 9th August, 2012
Work undertaken within ELR 94 during the period consisted of a review of past EM s urveys and RC drilling of oxide and sulphide zones, and determine if results are indicative of potentially significant sullphide mineralisation at depth. Past exploratory drilling has discovered new sulphide breccia beneath oxide at Doub le Bluff, Quartzite and Charlie, and will require further drilling to achieve JORC Indicated Resource category.
Charlie is interpreted as a vein plus breccia system. Charlie is a highly ranked target on the basis of historical activity, geological setting, and anomalous percussion drilling and ionic geochemical response. During November 2011, eight holes for 717m were completed at Charlie. Drilling encountered a structurally‐controll ed mineralised system, appearing to be steep and relatively high angle (NNE‐SSW) to the interpreted E‐W fault zone. 11BCRC‐06 reported 13m @ 1.37% Cu XRF from 9m, and 4m @ 1.2% Cu XRF from 36m (Table 1).
Past drilling at Quartzite (QT1, QT3) indicated sulphide ore at depth. Best assay result returned was 52m @ 1.34% Cu from 119m, which included 8m @ 3.98% Cu from 163m. 2011 field mapping indica tes that the mineralisation remains open to the west and northwest and requires detailed drilling to bring Quartz ite into the Indicated category. Track and drill pads were prepared during 2011, however, early wet season rains curta iled further drilling activity.
Double Bluff is a low grade copper pipe, with a sulphide target open at depth. Double Bluff was highly ranked on the basis of look‐alike targets, with a characteristic gravity low, magnetic low and geoche mically high signature identical to Bluff. During 2010, initial drilling defined an open large low‐grade copper oxide env elope ‐ >0.2% Cu, encountered in most holes (e.g. HoleDBRC10‐04: 35m @ 0.2% from 23m). Low grade sulp hide mineralisation was also encountered at the base of some holes, and a moderately‐ranked sulphide target rem ains at depth. In late 2011, tracks and drill pads were prepared for infill drilling on the 2010 drilling programme to determine the Indicated Resource status of the Double Bluff breccia pipe. Additional drilling was pl anned to determine if there is continuity of mineralisation between the Bluff and Double Bluff breccia pipes. As with the Quartzite drilling programme, inclement weather prevented further drilling at Double Bluff.

The re‐focus on exploration has been due to the identification of subtle copper anom alism associated with the newly‐named “Double Bluff” target, which has historically been dismissed as a ‘bleed ’ feature from Bluff itself. However the centre of the new anomalism is some 250m east of Bluff, over a hill and within a setting typical of other pipes, The Company considers the possibility of deeper copper sulphide minera lization, and more buried or sub cropping breccia pipes adjacent to known copper breccias such as Bluff ‐ Doubl e Bluff, Quartzite and AN9 ‐ AN9 Extended as high.
6.2 Geophysics No geophysical surveys were conducted over ELR94 during the reporting perio d.
6.3 Drilling
A limited RC drill programme, targeting sulphide
mineralisation beneat h known copper oxide
mineralisation, was conducted over a number of prospects within ELR 94, and commenced on the 11th
November 2011. Significant results from that drilling programme are detailed below (Table 1). Eight RC holes were drilled for a total advance of 717m.
TABLE 1: Summary of significant copper (CU XRF > 1.0%) Drill Hole intercepts on ELR94, for 2011‐2012 reporting period.
The company currently intends to continue drilling known copper breccia pipes, for oxide and sulphide potential, to increase the Company’s copper resource inventory. This will involve testing both outcropping and shallow‐covered targets for around 4000m of sulphide resource drilling, with the focus being on a HeliTEM survey to help delineate subtle sulphide targets at depth.
It is expected that expenditure on ELR94 (currently under application for a Mining Lease‐ ML27385) for the next field season will be in the order of $200,000.
