During the 2009-2010 project joint reporting year, the following activities occurred: - the conduct of an Aboriginal heritage work area clearance survey in the northern part of EL 3485 Tallaringa by the Antakarinja Land Management Council Native Title Claimants (ALMAC) in May 2009, and in the central and southern portions of both tenements in December 2009. The outcomes were the clearance of 6 drill traverses located within the pastoral station and 9 drill traverses within the conservation park; - acquisition in September-October 2009 of a ground gravity survey totalling 2885 stations, most of which were read on a regular 1 km x 1 km spaced grid. In addition to this semi-regional coverage, some of the gravity stations were read at 250 m intervals along three north-south profiles located in the north-east of EL 3485, which were orientated to try to define the IOCGU potential of selected discrete magnetic anomalies; - processing of the previous year's new airborne radiometric and magnetic data, and further processing of the TEMPEST AEM data from 2006 to calculate time constant grid values which helped to refine the likely position of palaeochannel features. Magnetic modelling undertaken over selected high frequency anomalies gave indicated source depths that ranged between 400 m and 800 m; and - the conduct during August-November 2009 of surface calcrete geochemical sampling over an 800 m x 800 m grid, when 1450 samples were collected on EL 3484 Mount Igy and 1040 samples on EL 3485 Tallaringa, in a systematic search for buried calcrete-hosted uranium deposits similar in style to WA's Yeelirrie. Areas of extensive sand dunes in the north and north-east of Tallaringa were excluded from this sampling. Results of laboratory analyses for 18 elements were treated statistically to determine anomalous samples relative to soil calcrete types; anomalism which was orders of magnitude greater than background in several elements was indicated for four zones within Mount Igy and three zones within Tallaringa. Three of the anomalous zones do not coincide with palaeochannel sediments, and would require infill sampling to delineate their relationship to older geological features. During the 2010-2011 project joint reporting year, the following activities occurred: - Quasar conducted an aircore traverse drilling campaign, of 131 vertical open holes with a total penetration of 8811 m, to investigate inferred Tertiary palaeochannel sediments for sedimentary uranium mineralisation. The position of the palaeochannel had been interpreted from the AEM survey data, and the twelve drill traverses were set out several km apart to delineate it. Holes were drilled at 400 m spacings. They were drilled to blade refusal, or were stopped once they had penetrated ~10 m into the interpreted Permian Boorthanna Formation clays lying below the channel sediments. 3098 x 2-metre composite drill cuttings samples were sent for laboratory assaying of a suite of 16 elements. The drillholes which returned the highest uranium values were re-sampled at 1-metre intervals in the vicinity of the anomalous grades. Downhole wireline gamma ray logging was conducted with an Auslog sonde which was run through the rods on completion of drilling, where possible. A radioactive mineral grade estimate was calculated from the gamma ray log response, but this was very low (maximum grade 0.007% eU3O8 over a 10 cm interval). Graphic traverse cross sections showing the lithological relationships between drillholes, as well as gamma ray log traces and uranium assay results, were constructed using Micromine. Two main sedimentary units containing porous sand horizons are recognisable throughout the channel system, which is hidden under a blanket of oxidised sands. These units have previously been interpreted to be the Pidinga and Garford formations (Walker et al., 2011). The lower, paludal Pidinga unit is strongly reduced, while the upper, lacustrine Garford unit is oxidised; often they are separated by several metres of purple to red plastic clay. The channel system in general is incised into thick grey - blue sandy clay of the Boorthanna Formation. Along most of the drill traverses, the base of this unit was not reached, however, under the three southernmost traverses located along the south-western edge of EL 3484 Mount Igy, a red and white limestone unit was encountered below the sandy clay. This was thought to be the Cambrian Observatory Hill Formation. On EL 3484, the highest assay result for uranium was 66.8 ppm U from the depth interval 46-50 m in hole IGA035. This level consists of reduced sandy clays within the lower palaeochannel unit. But 1-metre splits re-sampling of a lesser anomaly corresponding to the redox interface cut by hole IGA051 resulted in detection of an 8 m wide zone of anomalous values, the highest of which was 70.7 ppm U at 25-26 m depth. Elevated uranium values are present in adjacent holes at a similar stratigraphic level. Only weakly anomalous uranium assay results were returned by samples from holes drilled upstream on EL 3485 (maximum 36.1 ppm U from the depth interval 28-29 m in hole TLA017). No significant precious metal or base metal assay results were returned. But it was noted in passing that a few isolated elevated gold values occur within oxidised sands on the eastern bank of the palaeochannel [and coincidentally, at points adjacent to the Karari Fault zone]. During the 2011-2012 project joint reporting year, the following activities occurred: - the conduct of a further aircore drilling campaign focussed on renewed EL 4752 Mount Igy, where 84 vertical open holes for 4120 m were drilled along eight traverses over the period July-August 2011. This work targeted new positions along the Tallaringa Palaeochannel for uranium mineralisation or a suitable environment within the channel to host mineralisation, in the first instance using 400 m spaced holes. Infill drilling adjacent to radiometrically anomalous sediments intersected during 2010 was also completed, using 200 m hole spacings. Drillhole samples were logged and analysed using the same procedures as previously, excepting that they now were assayed for a larger suite of 22 elements. However, no uranium assay results obtained from the 1152 x 2-metre composite drill cuttings samples warranted their re-sampling to 1-metre depth intervals. Prior downhole wireline gamma ray logging had recorded very low grade uranium mineralisation estimates: the largest was 0.012% eU3O8 from 22.46 depth in hole MIG546, occurring immediately below the redox interface within strongly reduced sandy clay. The redox contact was identified in the majority of holes, and typically occurs between 10-30 m below the surface. Its expression varies, from being a short transition (<1 m), to a 6 m thick zone extending between the base of complete oxidation and the top of reduced lignitic sediments. It was observed that the surface sediments at all drill locations are strongly oxidised by haematite, limonite and goethite. Quasar surmised that the oxidation associated with the buried upper sediments encountered within the palaeochannel fill sequence represents a near-surface weathering profile as opposed to being an alteration cell caused by the flow of roll-front related oxidising groundwaters. The underlying reduced sediments in the palaeochannel are associated with varying concentrations of lignite. There was no significant change in oxidation observed within the palaeochannel fill sediments lying beneath the base of the surface weathering profile. Accordingly Quasar thought that this redox interface at the base of weathering would be the most likely locus for precipitation of uranium mineralisation, yet none appeared to be present, and therefore the company concluded that the potential for finding roll-front style uranium deposited within the palaeochannel proper is limited, because the passage of oxidised ground water carrying dissolved uranium has probably never occurred. Although laboratory assaying of drill samples had identified minor weakly elevated uranium (<150 ppm U) in reduced lignitic sediments at the base of the weathering zone, those anomalies are tabular in shape and Quasar believed that they have not formed as a result of roll-front uranium redox accumulation processes. Rather, it was interpreted that the tabular bodies are a result of seepage of low-U oxidising groundwaters through the weathered zone and then precipitation (i.e. reduction) upon contact with the underlying lignite. Therefore the JV partners now made a decision that uranium anomalism, where present, does not occur in concentrations high enough to warrant further drilling across the tenements. It was recommended that the surface and downhole geochemical data be reviewed for evidence pointing to possible existence of other deposit types and styles, before making any decision on ground tenure strategy. No further work was done on either subject tenement over the succeeding 32 months, before the decision was made to fully surrender them both.
