Summary In 2011, Pacific Consulting Services Pty Ltd (PCS) were commissioned as a geological consultant to KMC, in place of Teck Australia Pty Ltd. PCS recommended and produced a 1st draft of an initial data compilation and targeting review, which encompasses historical exploration data on and adjacent to the tenements, tenure statuses, geological and geophysical datasets, and exploration targeting. Historically, access impediments have resulted in limited exploration. PCS therefore believe the current tenements have potential for significant mineralisation, including base metals and uranium, however, due to remoteness and lack of infrastructure, exploration in this region will be comparatively expensive. For the next tenure year, 2011‐2012, PCS recommended an on‐ground review of the tenements, from which a detailed exploration proposal can be formulated and undertaken.

1. Introduction
An agreement between Teck Australia Pty Ltd and Kajeena Mining Company was established in 2002 to explore for base metals (Zn, Cu, Pb) and nickel over numerous tenements in the Warumpi Province of the Arunta. A Deed with the Central Land Council was executed in 2008 following successful negotiation with Traditional Owners to explore tenements 10383, 10385, 10386 and 10387. As of June 2011, Pacific Consulting Services Pty Ltd was employed as consultants to Kajeena Mining Company.
This annual group report details the work undertaken for the period 2nd September 2010 to 1st September 2011 ‐ the third year of exploration.
2. Location & Environment
The tenements are located approximately 270km W‐NW of Alice Springs and extend non contiguously to the Western Australian border, a further 220km as shown in Figure 1. The area is semi‐arid with variable vegetation, casuarina, wattle and eucalypts. Significant outcrop is generally limited to resistive Heavitree Quartzite and soils are Aeolian with occasional areas of lag and calcrete. Termite mounds are infrequent.

3. Tenure, Land Access and Heritage Clearances EL # Status Date Effective Grant Status Area (SBKS) Area (km2)
Negotiations with Traditional Owners to grant the tenements were successful, with the tenements granted on 2nd September 2008 following execution of an Access Deed with the Central Land Council.
Following preparation and submission of a work plan, a heritage survey was coordinated with the assistance of the Central Land Council over EL’s 10386 and 10387. The resulting report excluded areas from exploration approximating the relinquished areas A‐F in Figure 2, and areas A‐E in Figure 3. Without the possibility of accessing the areas, the ground was relinquished.

Figure 3: EL 10387 Initial Relinquishment
4. Geology EL10383 predominantly comprises geology of the Aileron Province, with the south‐western corner straddling the Warumpi Province and part of the Amadeus Basin extending to the north‐west. Beneath the drift, the Aileron Province geology is typically indicated to comprise metamorphic schists and metagreywackes occasionally intruded with mafic amphibolite sills (Lander Rock Beds), and further intruded by doleritic‐gabbronitic dykes (Du Faur Suite). The remaining geology comprises metamorphosed foliated quartzite (Warumpi Province Sandy Blight Quartzite), and sedimentary conglomeritic sandstone and interbedded siltstones (Amadeus Basin Heavitree Quartzite). EL10385 comprises geology of the Warumpi Province, with the north‐western and southern extents comprising part of the Amadeus and Canning Basins. Beneath the drift, the Warumpi geology generally comprises a combination of mafic and felsic igneous granodiorite (Waluwiya Suite), charnokite (Russel Charnokite of Waluwiya Suite) gabbro (Yaya Domain), and calc‐silicates (Yaya Metamorphic Complex). In addition, intrusive granites (Gunbarrel Granite of the Illili Suite) are present in the south‐west. The remaining geology comprises sedimentary conglomeritic sandstones and interbedded siltstones (Amaedus Province Carnegie Formation), and sandstone breccias (Canning Basin Ligertwood Beds). EL10386 geology is predominantly of the Warumpi Province and Amadeus Basin. Underlying the drift, the geology is indicated to comprise a combination of igneous intrusives (Warumpi Province Waluwiya Suite) across the northern part, and calc‐silicates (Warumpi Province Yaya Metamoprhic Complex) across the mid‐area. The southern part of the tenement is likely to comprise a combination of granites (Warumpi Province Udeor Granite) and sandstone conglomerates (Amadeus Heavitree Quartzite). The majority of EL10387 geology comprises Warumpi Province, with part comprising the Amadeus Basin. Beneath the drift, the majority of the Warumpi geology is made up of felsic igneous granodiorites (Yaya Domain), granites; leucogranites; and metamorphic schists (Udor Granite; Peculiar Complex; and Putardi Quartzite of the Haasts Bluff Domain). The Amadeus geology is conglomeritic sandstones (Heavitree Quartzite).

5. Current Exploration 2008‐2009 Exploration undertaken by Teck Australia undertook targeting involving the integration of expert weighted layers of geology, structural data, magnetic and spectral anomalies, resulting in the delineation and prioritisation of exploration targets. This process is described in detail in the 2008‐2009 annual report 2009‐2010 Teck Australia Pty Ltd undertook heritage clearances which were completed over prospective areas of EL’s 10386 and 10387, resulting in large areas of prospective ground being excluded from exploration. Reconnaissance sampling was completed over the remaining areas with soil (231 No.), rockchip (19 No.), leaf (215 No.) and termite (1 No.) samples collected. No additional sampling was completed over EL’s 10383 and 10385. Areas excluded from exploration were later relinquished. In collaboration with the NTGS, Teck Australia funded a regional gravity sampling program infilling 4km spaced sampling with 1km and 2km spaced sampling. Due to inclement weather delaying the sampling program, the data was not received until the 29th of October 2010. The purpose of acquiring the data was to support regional targeting, particularly for IOCG and other intrusive related systems. Whilst the data was being collected, prospect scale exploration was advanced at the Glam Rock prospect on EL10386. Detailed prospect scale exploration was completed at Glam Rock, following up the presence of trace copper in meta‐sedimentary rocks previously encountered during regional sampling. The program comprised 100m spaced ground magnetic traverses and 200m x 200m grid sampling of soil (317 No.), leaf data (274 No.) and collection of rockchips (55 No.), supporting detailed mapping and petrography. Typical grades of copper mineralisation from prospective units range 0.15% to 0.25% Cu with elevated gold values to 132ppb, and associated As, Bi, Ag, and Sb. Total strike length of prospective stratigraphy interpreted from ground magnetics and from soil geochemistry is 2.5km x 0.5km. Mineralisation appeared to be limited to discrete horizons of metasediment interleaved with barren calc‐silicate/amphibolites lithologies. The potential for a large intrusive related system at Glam Rock was downgraded with no significant mineralisation identified and the elevated magnetic response being attributed to magnetite‐rich stratigraphy, resulting from metamorphism of Fe‐rich protoliths. The nature of copper and gold anomalism remains in question. Two other geochemical anomalies were identified from regional sampling. “Glam West” is a multi‐element base metal and gold anomaly interpreted from leaf geochemistry. “Arrow” is a multi‐element base metal anomaly interpreted from soil geochemistry. No further work was completed during this period.

2010‐2011 Kajeena Mining Company Pty Ltd resumed operation of the tenements in 2011, and Pacific Consulting Services Pty Ltd (PCS) were commissioned as geological consultants to KMC in June 2011. PCS recommended an initial data compilation and targeting review, encompassing historical exploration data on and adjacent to the tenements, tenure statuses, geological and geophysical datasets, and exploration targeting. A 1st draft copy of this review can be found in Appendix 1. In summary, historic exploration on and around the current tenements show KMC hold a strategic land package in this prospective and underexplored region. The CLC access impediments have resulted in limited exploration, and therefore PCS believe the current tenements have potential for significant mineralisation, including base metals and uranium. Exploration in this region will be comparatively expensive due to the remote location, lack of infrastructure, and cost of relationship maintenance.
6. Proposed Exploration for 2011-2012
Completion of detailed data compilation and targeting review;
Initial on‐ground review of tenements;
Detailed exploration proposals will be formulated based on the Data Compilation and Field Review;
Work program meetings with the CLC and TO’s.
Geological mapping, geophysical surveys and soil and rock sampling may be utilised to aid targeting for initial RAB drilling.

2. Introduction Kajeena Mining Company Pty Ltd (KMC) hold 23 tenements in the Warumpi Province – Amadeus Basin District of the Northern Territory. Geographically covering the area between Alice Springs and the Western Australian border. The underlying land title is generally Aboriginal Freehold Land (ALRA) administered by the Central Land Council. The Kajeena tenements cover the highly prospective and underexplored Warumpi Province and Amadeus Basin metasediments. The Warumpi province is prospective for base metals (Cu-Pb_Zn), Ni-Cu-Co and Au. The Amadeus is prospective for U (EL 10391, 10392, 10394, 24090, 10393, 10395 24667 & 24190). Teck Australia Pty Ltd has been conducting exploration on granted EL 10383, 10385, 10386 & 10387 under an arrangement with KMC. The status of the Deed with the CLC is not known. Exploration only covered EL 10386 and 10387. These tenements cover in part the Iwupataka Metamorphic Complex which is noted as highly prospective. It is unclear as to why EL 10383 & 10385 were not explored. The following review attempts to pull together a range of sources, including:
Historic exploration data; Tenement status, including Deeds with CLC and potential for uranium
exploration; Geological and geophysical datasets; Competitors activity, tenements and results; Exploration target appraisal;

5. Data Review of Individual Granted Tenements EL10383
Land Access With the exception of the sand ridges, the majority of the central tenement area is relatively flat‐lying, with the exception of the outcropping rock in the north‐eastern, mid‐eastern, and south‐western areas. Unsealed roads provide access to the eastern and southern part of the tenement. Geology The majority of EL10383 comprises geology of the Aileron Province, with the south‐western corner straddling the Warumpi Province and a ‘slither’ of Amadeus Basin extending north‐westwards from the southernmost extent. Due to the main tectonic events which brought these 3 main geological regions together, faulting is reasonably prevalent in the south‐western part of the tenement. The main fault is the east‐west Central Australian Suture, a strike‐slip fault which separates the Aileron and Warumpi, with several other subsidiary faults. The Amadeus geology appears to owe its presence to two northwest‐southeast orientated faults. The tenement is predominantly covered in Quaternary aeolian sand, deposited in NW‐SE orientated sand ridges. Localised irregularly shaped calcrete outcrops are also present at surface, with Colluvium in the far western and eastern parts of the EL. Beneath the drift, the majority of the Aileron geology appears to comprise the ‘Lander Rock Beds’ (LRB) – a quartz biotite‐muscovite schist and metagreywacke, occasionally with mafic amphibolite sills. The LRB appear to have been later intruded by thin doleritic‐gabbronoritic dykes (Du Faur Suite), roughly orientated east‐west. Whilst not indicated on the Mt Rennie map, due to drift, a granite/gneiss (Andrew Young Igneous Complex) may be present in the mid‐western part of the EL. The Warumpi geology comprises Sandy Blight Quartzite – a metamorphosed foliated quartzite and quartz‐muscovite schist. The Amadeus geology comprises the Heavitree Quartzite – a sedimentary succession of sandstone, conglomeratic sandstone, and siltstone. Exploration History * All government and open‐file data available in exported spreadsheets in project folder. Whole Rock Samples Within the tenement itself, 4 No. ‘Whole Rock’ samples have only been taken historically, no dates. 1 of the samples was of ‘metamorphosed mafic’ and 1 was of ‘granite’ (both sampled by NTGS), the other 2 sample lithologies are not identified (sampled by Geoscience Australia).

The December 2010 Annual Group Report produced by Teck Australia, for KMC’s 4 granted EL’s, mentions 323 vegetation samples which were obtained on EL10383 and EL10385 in 2008. This data however cannot be found and review of the analyses is therefore not possible. Stream Seds No stream sediment samples either in or in near vicinity of tenement. Rock Chips No rock chips have been taken within the tenement, however, the following elevated concentrations have been obtained in the near vicinity.

Drillholes No drillholes within the tenement. 5 No. RC drillholes were advanced (total 682m) in the late 1990’s. Assay data is currently unavailable – waiting on NTGS. Uranium Potential No assay results on or around tenement provide elevated U concentrations. Radiometrics display typically slightly elevated U concentrations over the igneous/mafic intrusions exposed at the surface. An elevated U concentration, however, is shown just to the east of the fault bifurcation in the SW part of the tenement. calcrete outcrop, or fault concentration. Possibly more mineralisation present buried beneath the drift.

EL10385
Land Access The tenement’s topography appears to gradually increase south‐eastwards, from approx. 500m in the west, up to 570m in the south‐eastern corner. Unsealed roads provide access to the western part of the tenement. Sand ridges across the majority of the tenement generally appear sparse, with an increase towards the south‐western and south‐eastern areas. In addition, an ‘Operational building’ is also present in the south‐western corner of the tenement. Geology The majority of EL10385 comprises geology of the Warumpi Province, with the north‐western corner and southern extents part of the Amadeus and Canning Basins. The main fault, the roughly northeast‐southwest orientated Yuwalki Fault, follows the divide between the Warumpi and Amadeus geology in the south‐western part of the EL, however, is shown to cut through the Warumpi geology in the eastern part of the EL. Numerous other north‐east to east‐west orientated inferred faults are to be present across the tenement, generally shown to be extensions of the Yuwalki Fault. The tenement is predominantly covered in Quaternary aeolian sand, deposited in NW‐SE orientated sand ridges – the ridges most common in the south‐western and south‐eastern area. Extensive areas of ‘soil’ and alluvium are present within the central to northern area of the EL, with more localised colluvium and calcrete outcrops. Hard rock exposure appears to be very limited and scattered. Whilst it is very difficult to understand the geology due to the limited exposure, the Warumpi geology generally comprises a combination of mafic and felsic igneous rocks of granodiorite (Waluwiya Suite), charnockite (Russell Charnockite of Waluwiya Suite) and hornblende‐bearing foliated gabbro (Yaya Domain). In addition, granite (Gunbarrel Granite of the Illili Suite) is shown to be present in the south‐western corner towards the Yuwalki Fault. Metamorphic diopside‐quartz‐anorthite‐titanite [calc‐silicate rock] (Yaya Metamorphic Complex) is also shown within the central area. The south‐western corner is shown to have some of the best exposure on the tenement. It appears to comprise a combination of the Amadeus and Canning Basins – the latter being the most southerly. The Amadeus geology comprises the Carnegie Formation, a sedimentary succession of sandstone, conglomeratic sandstone, and siltstone. The Canning Basin geology shows a large exposure of the Ligertwood Beds, sandstone breccias. In addition, a small claypan is shown within the south‐western part of the tenement on the topographic plan.

Drillholes No drillholes within the tenement. 2 No. exploration petroleum drill holes have however been advanced to the south of the south‐eastern corner of the tenement. These exploration holes were undertaken by Central Petroleum Ltd, date unknown. Both of these holes have been identified as ‘suspended’. No further information is available. Mines 2 No. gravel pits are present to the north and north‐west of the tenement. Uranium Potential No assay results on or around tenement provide elevated U concentrations. Radiometrics do not display any elevated U concentrations at shallow depth over the tenement. Potassium is indicated to have a relatively higher concentration across the majority of area.

EL10386
Land Access With the exception of sand ridges, the majority tenement area is relatively flat‐lying. An unsealed road cutting through the most northern part of the tenement appears to provide the only access. Geology EL10386 predominantly comprises geology of the Warumpi Province, with the southern part being part of the Amadeus Basin. The main fault cutting through the tenement is the Yuwalki Fault, and again, only appears to follow part of the Warumpi‐Amadeus ‘suture’; several other east‐west orientated inferred faults are shown to extend from the Yuwalki Fault in the southern area. A few other east‐west faults are also indicated in the northern extent of the EL, extending from a heavily faulted igneous (Waluwiya Suite) exposure immediately to the north‐west. The tenement is predominantly covered in Quaternary aeolian sand, deposited in NE‐SW orientated sand ridges, with alluvium/colluviums deposits also present in the south‐western area. Exposure is very limited, with indication that the igneous Waluwiya Suite extends across into the northern part of the tenement, and presence of diopside‐quartz‐anorthite‐titanite [calc‐silicate rock] (Yaya Metamorphic Complex) across the mid‐area. Whilst not included within the tenement boundaries, the southern‐most part of the tenement is likely to comprise a combination of Warumpi granite (Udor granite), and Amadeus crystalline quartz sandstone conglomerate (Heavitree Quartzite) ‐ faulted / igneous intruded. Exploration History * All government and open‐file data available in exported spreadsheets in project folder. Whole Rock Samples Within the tenement itself, 7 No. ‘Whole Rock’ samples have been taken historically. All samples were obtained by NTGS, un‐dated.

Soils & Vegetation Reconnaissance soil and vegetation sampling was undertaken by Teck Australia Pty Ltd, on behalf of Kajeena Mining Company Pty Ltd, in November 2009. More detailed ‘prospect sampling’, was undertaken at Glam Rock (NE of tenement) as a result of the above soil samples. This comprised a 200 x 200m grid spaced area sampled for soil and vegetation. From combination of the soils, veg and a field‐portable XRF, Results revealed elevated Cu, Au, Ag, As, Bi, Sb, and locally Zn. Teck believed the anomalies were considered ‘geochemical smoke’, despite widespread malachite and bornite mineralisation. In addition, Teck identified Glam West as a potential multi‐element base metal and gold anomaly, based on their leaf geochemistry.

Land Access With the exception of sand ridges, the majority tenement area is relatively flat‐lying. (the highest points, i.e. Mt Udor, etc, were excluded from the original EL application). Several localised ‘Native Vegetation Areas (Forest or Shrub)’ are scattered around the tenement. In addition, a few water points/bores are present in the area, one of which is located within the southern boundary of the northern half, and ‘Lizard Bore’ on the north‐eastern corner of the tenement. Access can be gained via an E‐W unsealed road which passes through the northern half of the tenement. Geology The majority of EL10387 comprises geology of the Warumpi Province, with only the south‐western and south‐eastern tips of the tenement comprising Amadeus Basin geology. The main fault cutting through the centre of the tenement again is the east‐west orientated Yuwalki Fault, with indication of thrusting in the easternmost part. The tenement is predominantly covered in a combination of Quaternary aeolian sand, alluvium, and soil/colluviums; the former deposited in NE‐SW orientated sand ridges in the southern half of the area. The majority of exposure is outside of the EL’s boundaries (perhaps due to being more significant and higher areas of ground), however, this geology can probably be assumed to underlay the drift within the EL... Generally the Warumpi geology in this area comprises felsic igneous rocks of granodiorite (Yaya Domain), granite (Udor Granite, Haasts Bluff Domain), and leucogranite (Peculiar Complex, Haasts Bluff Domain). Metamorphic rock of quartz‐muscovite schist (Putardi Quartzite, Haasts Bluff Domain) is also present within the southern half of the EL (south of igneous exposure). From what is exposed of the Amadeus geology, the crystalline quartz sandstone conglomerate (Heavitree Quartzite) is present within the southern extents of the EL and/or faulted/thrusted within parts of the Warumpi geology.

6. Uranium in the Region
Amadeus Basin Uranerz Australia Pty Ltd (Uranerz) commenced exploration for sandstone uranium deposits in the Amadeus Basin in 1972. Reconnaissance airborne spectrometry and ground surveys in 1972 identified several anomalies south of Alice Springs (Borschoff & Faris, 1990). Drilling of these anomalies during 1973 and 1974 led to the discovery of the Angela and Pamela deposits. From the mid‐1970s onwards the project was a joint venture between Uranerz and Carpentaria Exploration Company. Further drilling and mapping showed that the uranium mineralisation occurred along a redox boundary within sandstones of the Undandita Member of the Brewer Conglomerate. From 1975 to 1979 the Angela and Pamela deposits were delineated by detailed percussion and diamond drilling. A number of smaller zones of mineralisation associated with the Angela deposit were also drilled. Geology The uranium deposits are within the Undandita Member (sandstone) of the Brewer Conglomerate which is the youngest unit in the Amadeus Basin. The Undandita Member is the uppermost unit of the Pertnjara Group, a thick sequence of terrigenous sediments of Late Devonian to Early Carboniferous age. The Undandita Member comprises fine to coarse‐grained lithic sandstones, and medium to coarse‐grained lithic arkose interbedded with thin mudstone units. This sequence interfingers with the Brewer Conglomerate south of the MacDonnell Ranges and reaches a maximum thickness of 3000m in the Missionary Syncline, 15 km south of Alice Springs. The sediments are generally oxidised, but a wedge‐shaped zone of reduced sandstone is preserved within the sequence (Borschoff & Faris, 1990).
Ngalia Basin Uranium mineralisation was discovered in the vicinity of the Ngalia Basin (NT) in 1970 when a prospector employed by Central Pacific Minerals NL found radioactive gossanous material in a quartz vein in a granite of the adjacent Arunta Complex to the north of the basin. This prospect was later named Rankins Reward. Further ground prospecting located carnotite in outcrops of the Mount Eclipse Sandstone. The Bigrlyi deposit was discovered in 1973 by ground radiometric traversing and follow‐up drilling. Uranium mineralisation was subsequently found in thirteen separate zones in the Mount Eclipse Sandstone (Fig. 35) (Ivanac & Spark, 1976; Fidler, Pope & Ivanac, 1990). In 1973, uranium mineralisation was discovered in Quaternary and Recent calcrete in the southern part of the basin.
Geology The Ngalia Basin is an elongate, intracratonic downwarp filled by Neoproterozoic and Palaeozoic strata. The basement rocks are highly deformed metamorphics, granites and sediments of the Palaeoproterozoic Arunta Block (Wygralak & Bajwah, 1998). Continental and marine strata of Neoproterozoic, Cambrian, Ordovician, Devonian and Carboniferous age comprise the Ngalia Basin sequence. The sequence has been divided into eleven formations with a maximum aggregate thickness of about 7500m (Wells & Moss, 1983). Most formations are bounded by unconformities. The strata are mainly arenaceous, with interbedded dolomite and shale. Uranium mineralisation is in the lower part of the Late Devonian to Late Carboniferous Mount Eclipse Sandstone. The host rocks are medium‐ to coarse‐grained feldspathic sandstone with carbonate commonly forming a cement. The
34
sandstones are mainly red, but restricted zones of light to dark grey are also present (Fidler & others, 1990). Minor amounts of shale, siltstone, conglomerate and dolomite are interbedded with the sandstone. The sandstone along the northern margin of the basin is thrust‐faulted and folded. Carnotite is the main ore mineral in the weathered sandstone, with uraninite in the primary zone. Carbonaceous material, including plant remains, is common in the reduced parts of the sandstone. Quaternary calcrete containing minor carnotite mineralisation has formed in the southern part of the basin where there is a broad area of lagoons, salt‐pans and stream meanders related to the present drainage system. Genesis Uranium mineralisation in the Ngalia Basin is closely associated with those parts of the Mount Eclipse Sandstone that contain carbonaceous detritus. Prior to diagenesis, run‐off from the surrounding highlands permeated the sandstones and migrated into the sediments. In the oxidising environment these waters transported uranium and vanadium which were released from the basement rocks by weathering (Fidler & others, 1990). This uranium and vanadium precipitated in the reducing environment created by the presence of carbonaceous material and pyrite in the sandstones.
35
Sandstone‐type uranium occurs on the northern margin of the Amadeus Basin in the Late Devonian Undandita Member of the Brewer Conglomerate. This is the youngest preserved unit of the Amadeus Basin succession and consists of fluviatile pebbly sandstone, minor siltstone and conglomerate Ref’s: ‐ Australia’s Uranium Resources, Geology And Development of Deposits, A.D.

Australia with the potential to host multiple world‐class gold discoveries in excess of 5 million ounces. ABM’s main project is ‘Twin Bonanza’ in the Tanami Region of the NT. Lake Mackay Project
The Lake Mackay Project area is located approximately 400km west-northwest of Alice Springs in the Northern Territory. Reconnaissance work by Tanami Gold and other previous explorers revealed several areas of enhanced anomalism in copper, gold and other base metals.
ABM has completed data integration and targeting on three prospects with multiple targets in the Lake Mackay Area. In addition, results from a recent Induced Polarization geophysical survey have been received.
Previous shallow RAB drilling intersected up to 16m @ 3.4g/t gold; 4m @ 2.67% Cu at the Tekapo prospect with Rock Chips up to 32.58g/t Au. The regolith geochemistry and shallow drilling defined a copper-gold-bismuth anomaly over 1.2km by 0.6km and the induced Polarization Survey reveals underlying modelled chargeability anomaly of 2km x 2km.

Roll front mineralisation) (Daria – as Nonouba) EL24606 – Aileron Prov (Lake Lewis) EL25698 – Aileron Prov EL25701 – Aileron Prov Uranium deposits in EL:
‐ Angela – medium sized deposit, located in the Brewer Conglomerate. Roll front
mineralisation.
‐ Pamela – as above.
The target within the majority of the tenement areas is near surface calcrete‐hosted uranium mineralisation similar to the Napperby deposit. The potential for this style of mineralisation occurring in shallow buried channels (palaeochannels) downstream from ‘hot granites’, can be rapidly assessed by remote sensing utilising night‐time aster imagery or by airborne electromagnetic surveys with follow‐up 1 to 2 kilometres spaced shallow drill traverses. Roll‐front uranium mineralisation is also being targeted at Nonouba west of Alice Springs. The western Napperby Project exploration licence is considered prospective for both styles of uranium mineralisation. Napperby: EL24606 & EL24246 Napperby calcrete‐hosted uranium deposit with an Inferred JORC Code mineral resource of 9.34 Mt at 359ppm U3O8 for 3,351 tonnes (7.39 Mlbs) as part of a larger mineralised system. Napperby’s historic mineralised zone comprises anon‐JORC compliant, resource of 17.1 Mt @ 350 ppm U3O8 containing 13.2 Mlbs of U3O8 (200 ppm cut‐off) which contains the JORC resource area. The Napperby calcrete‐hosted uranium deposit occurs in a relatively ‘young and shallow’ palaeochannel system developed within the Tertiary – Quaternary Burt Basin. The sand and weakly consolidated/cemented sediments hosting the deposit overlay Palaeoproterozoic basement rocks which regionally have potential to host, gold, base metals and IOCG(±U) deposits. Napperby Deeps – basement hosted IOCG±U targets: During the period of the Toro option over the Napperby deposit, DYL and Toro entered into a 50/50 joint venture to test magnetic/gravity targets developed in basement terrain within ELs 24246 and 24606. The JV undertook a gravity survey and drilled two RC/diamond tail holes to test two of five drill targets. One hole failed to reach basement and the second hole intersected magnetite bearing granite in part explaining the gravity/magnetic anomaly at that location. DYL are going to assess the ‘Deeps’ programme with a view to continuing exploration if and as warranted.

Airborne radiometric data indicates that uranium enriched material is present in these drainages and is depositing around the margins of Lake Lewis and at trap sites along the drainage system. A number of target areas have been identified from interpretation of radiometric data and investigation of historical open file data. Of particular significance is the Mount Wedge Prospect discovered by Uranerz (Aust) P/L during the late 1970's. A number of significant uranium occurrences are located within the basin including the Bigrlyi Uranium deposit, 10,590 tonnes at 0.14% U3O8. The Bigrlyi Uranium deposit, a modified roll front style, covering a stike length of 12 km was identified in 1973 during basin wide exploration undertaken by Central Pacific Minerals NL and is now held by Energy Metals Limited (53%). Current Exploration Aircore drilling conducted by the company, 4005 holes for 10,818m, has targeted near surface calcrete hosted uranium mineralisation (similar to the adjacent New Well Uranium Deposit) within a large regional drainage system and potential targets interpreted from the 2007 TEMPEST electromagnetic survey. These targets include including buried channels and palaeo‐lake margins. The drilling intersected surficial red‐brown, sandy soil (thickness 1‐6m) overlying up to 9m of red‐brown calcrete and silts with a basal calcrete layer. This horizon which returned a number of anomalous uranium intersections from 3m composite sampling, including 50 ppm U from 6‐9m from drill hole ECAC 199, overlies transported silts, clays and sands which in some places attain depths of greater than 70m.

TORO ENERGY LTD http://www.toroenergy.com.au EL’s in vicinity: EL27900 – Aileron Prov EL27970 – Aileron Prov Amadeus Basin Toro have several EL’s in the Amadeus region, just to the west of Alice Springs. NT TIS shows all of Toro’s EL’s in this region are still in application, despite their website stating that a few of these tenements are granted. The Toro website summarises the following: The tenements cover part of the mapped Hermannsburg Sandstone which stratigraphically equates with Pertnjara Group comprising Upper Devonian – Lower Carboniferous fluvio–continental sediments. This sequence and its equivalents hosts the Pamela and Angela uranium deposits south of Alice Springs and the Bigrlyi, Walbiri, Malawiri and Dingo’s Rest uranium deposits of the Ngalia Basin to the north. Uranium mineralisation in the Ngalia and Amadeus Basins is localised at redox interfaces in the Devonian‐Carboniferous sequence. These interfaces can be peneconcordant or lateral or both. They are stratigraphically related to the tops or lateral terminations of reduced sequences contained in oxidized, red‐bed sequences. The reduced beds are grey or sometimes white where bleaching has occurred by oxidation of sulphides (pyrite). Pamela
42
and Angela are hosted in the upper‐most member the Undandita Member. The Bigryli deposit is hosted towards the top of the Mt Eclipse Sandstone. The other deposits in the Ngalia Basin occur at a similar stratigraphic level. In the central Australian Fold Belt, there is evidence of significant remobilisation of uranium from the radiogenic Arunta basement into the overlying Proterozoic, Palaeozoic and Tertiary sedimentary cover units, including the Ngalia, Amadeus and Tertiary Basins. The uranium deposits at Bigrlyi, Napperby (New Well) and Angela attest to this. In the vicinity of the Amadeus West tenements (ELs 25049 and 27183), there is exposure of an exhumed Tertiary palaeochannel with a strong radiometric signature. The origin of this signature is unknown, but is likely to be surficial enrichment of uranium and other radionucleiides onto ferruginous crusts on outcrop. However, this may be an indicator of subsurface primary mineralisation. Kintore Project ELA27573 – Aileron/Warumpi/Ngalia Prov This project is immediately adjacent to EL10383. No previous exploration. Exploration is unlikely to commence before 2012. The Toro website summarises the following: This project area lies at the boundary between Palaeo‐ to Meso‐proterozoic metamorphic rocks of the Arunta Complex (Warumpi Province and Aileron Province) and the Amadeus Basin. Basement consists of greenschist to amphibolites facies schist, after a protolith of greywacke, siltstone and quartzite, modified locally by thermal metamorphism associated with granitic intrusions. Also present is highly altered, flow‐banded and brecciated lava and high level, comagmatic granites of the Mount Webb Complex. These igneous units are notably radiogenic and are thought to be the ultimate source of uranium in Tertiary sediments in the adjacent Lake Mackay Project. Dividing the older Aileron Province and the younger (accreted terrain) Warumpi Province, is the Desert Bore Thrust, a crustal scale suture, sometimes called the Central Australian Suture. The unconformably overlying Peculiar Volcanics consists of acid and mafic volcanics, with intermingled sediments. This unit may belong to the overlying Amadeus Basin, but geochronology is not available as yet. Basement rocks are overlain by Neoproterozoic to Carboniferous sediments of the Amadeus Basin, a foreland basin developed during episodic deformation along the Central Australian Suture. In the Kintore Project, there is a veneer of Tertiary to Recent clastics of unknown thickness, derived from erosion of the radiogenic granites. Current drainage and possibly historic drainage is to the west toward a regional low‐point, Lake MacDonald. This situation is analogous with the Frome Embayment in South Australia, which hosts the Beverley and Four Mile uranium deposits. It is also similar to the setting of the Theseus Prospect in the Lake Mackay Project. Most notable in the area is a high‐amplitude uranium channel radiometric anomaly located over the edge of Lake MacDonald. The radiometric feature is likely due to radionucleiide daughters that have been discharged into the Lake via modern groundwater flow. The ultimate source of the radionucleiides is speculated by Toro to be a concealed uranium
43
mineral system to the east of the Lake within the Kintore Project. Three potential geological scenarios are envisaged: • Iron Oxide‐Copper‐Gold+/‐Uranium (IOCG‐U) ’Olympic Dam style’ mineralisation in the Mount Webb Complex. This rock unit is similar in age and composition to SA’s Gawler Craton, an established IOCG‐U domain. Ashburton Minerals has drilled wide intersections of Cu‐Au mineralisation at Pokali South, 50km west of the Kintore Project. • Sandstone‐hosted ‘Angela style’ mineralisation within the Amadeus Basin. This Basin has Carboniferous organic‐bearing sediments that could host ‘roll‐front’ type uranium deposits similar to Bigryli and Angela in the Ngalia and Eastern Amadeus Basins respectively. • Palaeochannel mineralisation in buried sand units that drained toward the former Lake MacDonald, akin to the Beverley uranium deposit in South Australia. The presence of palaeochannels is predicted based on exploration results in the adjacent Lake Mackay Project. • Calcrete‐hosted ‘Yeelirrie style’ mineralisation within shallow sediments at the fringe of Lake MacDonald. Toro believes the geological setting is analogous with the Toro‐owned Lake Way and Centipede deposits (Wiluna project) in Western Australia, where uranium mineralisation has developed at the deltaic interface of palaeodrainages and saline lakes.
44
Ngalia Project EL27900 – Aileron Prov EL27970 – Aileron Prov Toro advise that uranium exploration is quite mature in this area, however, there are areas that still remain unexplored – probably due to the lack of surficial radiometrics. Whilst they haven’t undertaken any significant exploration (i.e. drilling), they will employ electromagnetics and gravity geophysical methods to determine older buried Tertiary palaeochannels and calcrete remnants that might host “blind” uranium deposits. The Toro website summarises the following: This project lies within the Arunta‐Ngalia region of the Northern Territory. Basement is comprised of Palaeoproterozoic to Mesoproterozoic metasedimentary and granitic rocks assigned to the Aileron Province, including the Reynolds Range Group. These granites and orthogneisses are notably radiogenic and are overlain by Neoproterozoic to Carboniferous sediments of the Ngalia Basin in the north. The Aileron Province and Ngalia Basin rocks are largely overlain by a veneer of Tertiary to Recent clastics, derived from erosion of the radiogenic granites in the Reynolds Range, MacDonnell Ranges and Ngalia Basin. This situation is analogous with the Frome Embayment in South Australia, which hosts the Beverley and Four Mile uranium deposits, the former of which has been in production since 2000. Uranium mineralisation is known in the region and is restricted (thus far) to the Proterozoic Aileron Province, the Devonian to Carboniferous parts of the Ngalia Basin, and in Tertiary sediments and calcrete. Uranium at Nolans Bore (Arafura Resources) occurs in phosphatic and REE‐enriched metasomatic pods and veins within the high‐metamorphic‐grade Lander Rock beds. This deposit is subject of ongoing feasibility studies by Arafura Resources. Crossland Uranium has also identified interesting grades of primary ‘hardrock’ uranium with the Tea Pot Granite, which makes up the large radiometric anomaly within the MacDonnell Ranges (Figure 3). Uranium is also present in high grades at Bigrlyi (Energy Metals‐Paladin JV) to the northwest, within carbonaceous sandstones of the Mt Eclipse Sandstone. The deposit is a roll‐front style formed during uplift and deformation of the Ngalia Basin in the Carboniferous Alice Springs Orogeny. Uranium has also been identified by Thundelarra immediately to the north in Tertiary lignite‐bearing palaeochannel sands. Central to the Ngalia tenements is the Napperby (New Well) uranium deposit (Deep Yellow), which is made up of carnotite hosted in dolomitic clays, sands and dolocrete. During the period 2007‐2010, Toro as operator undertook resource definition drilling and a scoping study, but were not able to advance the project further in the economic conditions at the time. Palaeochannels are interpreted to have developed during the Tertiary within the foreland outwash fans prograding south of the Reynolds Ranges and north of the MacDonnell Ranges, carrying immature detritus into locally reduced and evaporitic settings around Lake Lewis and along strike where precursor lakes existed. Subsequent uplift events in the ranges generated topographic head and forced oxidised uranium‐carrying fluids from the hinterland northward into the reduced palaeochannels. Uranium was likely to be dropped out of solution as the chemical ‘roll‐front’ moved northward. The hydrodynamics of the region may also support the view that the ‘roll‐front’ system is currently active and any uranium deposits that are present are actually forming and dispersing within the modern timeframe. The Beverley ISL uranium mine in South Australia is a good example of this type of deposit and is one of the analogues for Toro Energy’s exploration in this project. The Napperby
45
deposit is thought to have formed as a result of the evaporation of these oxidised fluids where they discharged at the edge of Lake Lewis. Older calcrete uranium systems are envisaged along the trend of the former lake system during the Tertiary. These systems are the main focus of Toro’s exploration in the southern tenements of the Ngalia Project.

They believe the area has potential for sediment‐hosted uranium deposits. Previous bores drilled in the area identified the uranium as potentially mobile, and could be
46
sourced from the Teapot Granite (which they say their geophys has identified as highly radioactive), which is an ideal source for uranium in calcrete and channel hosted deposits such as others in the district, at Napperby, Bigyrli, and Angela-Pamela. They advise that there are two possible deposit types, or a combination of the both types in one deposit as occurs elsewhere in this region, at Napperby. Calcrete is present in the fluvial channels and is present in outcrop during field inspection; lignite is also known, and if a source of vanadium is required to precipitate carnotite, the basic intrusive bodies of the Mount Hay layered complex lie below the fluvial channels to provide this. The area also has potential for Rare Earth Elements, as outlined below. Cockroach Dam Uranium Prospect Results: In December 2010, an announcement was made for drilling of 7 holes in the Charley Creek Project area. They had a best intersection of 2m@876ppm U3O8 from 148m, including 0.3m@4,079ppm U3O8 from 148.8m. Intersections of the granite revealed 10 times average U content of up to 40ppm. No further information. REE Results: In March 2011, CUML JV announced additional results for Rare Earth Elements (REE) in the Charley Creek area. In November 2010, CUML announced an alluvial sample revealed heavy minerals contained REE with total TREO of 39%. The REE are present in phosphate minerals, with the REE easily extractable. There appears to be relatively high concentrations of all of the heavy REE’s (above europium in Periodic Table). This has since been followed up and they undertook stream sediment sampling of over 4000km2 at Charley Creek; auger drilling of alluvium in the Cockroach Dam Prospect area; and re-analysed 2008 drill pulps. Of the 195 stream sediment samples analysed, 74, or 38%, returned over 2%TREO, 45 samples returned over 4% TREO, 25 over 8%, 12 over 16%, and three returned over 32%TREO, with a maximum of 38.4%. Each of these samples represents between two and four square kilometres of drainage basin. Over 700 samples taken of augering, awaiting results. Re-analysis of the pulps demonstrated local bedrock REE sources beneath the plains of the Charley Creek basin. REE Conclusion (extract of announcement): Much of the lower country in the Charley Creek Project Area is underlain by Tertiary sediment, or younger alluvium, in places up to 150m thick. In the vicinity of Cattle Creek, it appears from our drilling that this cover is thin to non- existent. The intersection in CCA121 drill hole is in basement gneissic rocks, and the mineralisation is in place, not transported in alluvium. It seems likely that the nearby anomalous heavy mineral results in stream sediments are derived from erosion of a local bedrock source. Since three of the stream samples drain country upstream of the drill hole, there is potential for the source to be quite extensive. Early information suggests that mineralisation at Cattle Creek is also monazite. The REE profile is quite flat, which means that heavy REE are present in relatively higher amounts than in the alluvial monazite. Also, unlike the detrital heavy minerals from the project, the commonly observed depletion of europium characteristic of monazite derived from granitoids is not pronounced. This indicates that the bedrock mineralisation has an even
47
more attractive mix of REE than has yet been observed in the alluvial heavy mineral samples.

...is a gold and nickel explorer in Australia and Poland. EL’s in the vicinity EL24438 – Warumpi Prov (Stokes Yard Project) EL24948 – Amadeus Basin (Crawford Creek) EL24961 – Amadeus Basin (Camel Prospect) EL28255 – Amadeus Basin On their website, NMI state that their Northern Territory prospects are situated in a highly prospective area for manganese, gold, REE, uranium and base metals. EL24961 – 2 Mn prospects identified, 23km apart in same EL. Rock chip assays have revealed high Mn concentrations of up to 45.6% announced in Sept 2010. NML are vague as to what the mineralisation host rock is / owed to, however, they describe a few outcrops which are generally sub‐parallel to sedimentary bedding, up to 2‐3m wide and 5m deep, and exposed for 40m to a 1,200m discontinuity before disappearing under shallow cover. EL24438 – magnetic and radiometrics flown in 2010 revealed additional targets. Previous results from surface sampling have produced high grade zinc 26%, lead 7.5%, copper 7.5% and silver 130ppm. EL24948 – potential for REE‐U‐Th‐rich dykes, nickel, zinc, copper cobalt occurrences.
RED GUM RESOURCES PTY LTD http://www.redgumresources.com EL’s in vicinity EL25144 – Amadeus Basin (Eucalyptus Project Area) EL25145 – Amadeus Basin (Eucalyptus Project Area) EL25213 – Amadeus Basin (Acacia Block) RGR’s cumulative interest in the Amadeus Basin is 7,306.7km2, which represents the largest strategic holding of mineral exploration tenements within the basin. Exploration for base metals within the Amadeus Basin took place 1950’s onwards, although has been significantly hindered by issues of Native Title and ALRA (Aboriginal Land Rights Act) land. Historically, copper mineralisation has been found on the contact between the Goyder Formation and Pacoota Sandstone, in hydrothermal sandstone hosted deposits, or on faulted contacts that juxtapose younger sandstones against older source & host sediments (frequently shows noted as ‘sedimentary Cu’). Exploration has yielded a small copper body in the Waterhouse structure and government drilling resulted in assays of up to 2500ppm Cu at the Ringwood prospect, where visual Malachite, Azurite and Chalcocite can be (reportedly) traced in a green dolomitic unit along a strike length of approximately 8km.

RGR state that their EL’s cover areas of analogous geology to that of areas with known copper‐lead‐zinc‐silver‐gold mineralisation. EL25213: The eastern Amadeus Basin is a structurally complex area that has been strongly affected by the numerous deformation events. EL25213 is bound by faults to the south and east, which compartmentalize highly deformed sediments and structures in the general area. The Camel Flats Syncline is to the south of the tenement, whereas an un‐named structure lies to the east (referred to as the Acacia Anticline complex), and the greater Ooraminna structure lies to the north. Neoproterozoic through to Ordovician stratigraphy is present within the EL. EL25144 & EL25145: The Eucalyptus Project area comprises a series of east‐west oriented south verging thrust faults that offset stratigraphy from the basement to the surface. Outcropping sediments range in age from the Neoproterozoic to the Tertiary and comprise interbedded sandstones, shales, carbonates and occasional conglomerates. The age of the faults is interpreted to be around 600Ma (approximate time of the Petermann Orogeny). It is quite likely that these may have been reactivated at other times, notably during the Alice Springs Orogeny. Unfortunately, no further information is available on their website, nor is their company present on the ASX, as advertised on their website.
URANEX NL http://www.uranex.com.au EL’s in vicinity EL25578 – Amadeus Basin Project is prospective for sandstone hosted uranium deposits similar to the nearby Pamela/Angela (Cameco) and Napperby (Deep Yellow) deposits. Field recon and desktop studies have commenced at the project, with an initial drilling programme planned for 2011.
CAMECO / PALADIN ENERGY http://www.paladinenergy.com.au EL’s in vicinity EL25758 – Amadeus Basin Uranium deposits in EL:
‐ Angela – medium sized deposit, located in the Brewer Conglomerate. Roll front
mineralisation.
‐ Pamela – as above.

As advised on their website: The Angela Uranium Project Joint Venture parties have committed to a comprehensive confirmatory and exploration work programme as well as a pre‐feasibility study which if successful, will then progress to a Bankable Feasibility Study and an Environmental Impact Assessment. Extensive evaluation work was undertaken previously on the Angela and Pamela uranium deposits by Uranerz Australia Pty Ltd between 1972 and 1983. Based on the examination of all digitised and validated historical information the Company has formulated an exploration target of approximately 12,000t to 13,000t of U3O8 in the general range of 0.10% to 0.13% U3O8 and this mineralisation appears to remain open at depth and laterally. Amalgamation of all this historical data, with drilling finished in 2009 and early 2010, should be completed in the first half of 2011 when an initial Mineral Resource estimate conforming to both JORC (2004) and NI43‐101 guidelines is expected to be estimated. The JV drilled over 5,000m during the first half of 2010, however, drill results are not available. However... The most recent announcement on this project is a letter on the ASX stating Paladin are surprised by the announcement that the Northern Territory Government would not support the establishment of a uranium mine at Angela Pamela, south of Alice Springs. Further action/discussion would be pursued.
