An area centred ~28 km east of Hawker is being explored for possible buried epigenetic/hydrothermal, skarn style and sediment-hosted stratabound base and precious metals mineralisation that may have formed within prepared Adelaidean metasedimentary units in proximity to intrusive diapiric structures and related faults. Following receipt of a grant of $325,000 of Accelerated Discovery Initiative 50% subsidy funding from the SA Government, EL 6541 licensee Taruga Minerals embarked on an approved project work programme comprising exploratory drilling, detailed prospect-scale geophysical surveying, and a related local community-building and business support component involving aboriginal worker technical skills training and employment. The drilling was performed in two separate campaigns, the first consisting of RC drilling of 65 inclined or vertical holes at the Wyacca and Morgan Creek prospects during June 2021, and the second consisting of diamond drilling of 7 inclined holes at these two prospects during September-October 2021. A total of 6181 m of RC penetration and 601 m of diamond coring was completed, at an overall cost of $957,012. Two kinds of geophysical survey were performed during October 2021. Detailed gravity readings were acquired from 2612 new stations over four grids surveyed at the Wyacca, Morgan Creek, Birthday Ridge and Iron King prospects, starting with a 400 m x 400 m station spacing and infilling that to 50 m x 200 m/400 m precision. A ground magnetic survey totalling 192.3 line km was read over three grids at Wyacca and at Morgan Creek East and West, along east-west traverse lines spaced 50 m apart. The actual total cost of performing these two surveys and then doing associated geophysical data inversion modelling is estimated to be close to $144,500. Within the grant funded RC drilling programmes, Taruga primarily aimed to build on earlier work by: - testing copper grade and mineralised width along strike and down dip from previous intersections and beneath outcropping mineralisation at Worumba 19 and Powder Hill (Worumba 20); - testing significant VTEM chargeability anomalies along strike to the east of Worumba 19. One significant VTEM anomaly along the geophysical trend of the Tindelpina Shale has the potential to represent a large volume of sulphide mineralisation occurring at the target horizon; - testing for copper anomalism at the base of the Tindelpina Shale across an interpreted structural corridor thought to be related to the historic Worumba 21 mine; and - testing the Worumba 21a historic workings for copper grade and mineralised width down dip from outcropping gossan. The ADI project's diamond drilling programme was designed to test the different known styles (for example supergene and hypogene) of mineralisation at each of the main prospects and their discrete subareas. Primary aims were as follows: - to gain an understanding of ore genesis, including textures of mineralisation and alteration, ore mineral assemblages and controls on mineralisation; and - to enable the company to undertake a structural analysis to ascertain any major structural controls and key structural trends. The Wyacca prospect RC drilling programme was undertaken first, and yielded immediate success in meeting the technical objectives laid out for it in the ADI funding proposal. At Worumba 19, 1485 m were drilled with the aim of extending known mineralisation down dip and along strike. Mineralisation of varying grades and widths was intersected in all holes which penetrated the target horizon, thereby conferring a high level of confidence in the continuity of mineralisation here. At Worumba 20, a total of 900 m of drilling intersected copper grading over 1% Cu, including 1 m @ 1.6% in hole WCRC054 and 1 m @ 2.17% Cu in hole WCRC060. The drilling highlighted that the base of the Tindelpina Shale is not the only mineralised unit in the lower Tapley Hill Formation in this area, thus giving potential for stacked lenses of stratiform copper mineralisation where structural conditions are favourable. To the east of Worumba 19, there is a large area of previously unexplored ground in which the Tindelpina Shale lies in contact with the Wilyerpa Formation. Large VTEM anomalies and a structural corridor were interpreted by Taruga from geophysical data images, and these were tested with 1482 m of drilling. Due to a change in the dip angle of the buried strata, many holes did not reach the target horizon, but provided valuable stratigraphic information for future work. Holes which did intersect the target horizon recorded anomalous levels of copper (up to 0.5% Cu over 1 m in WCRC045) plus visible sphalerite and galena, in addition to alteration in the wall rock. During September 2021, 3 inclined diamond cored holes were completed on Wyacca prospect as proposed: WCDD001 to TD 118 m at the Worumba 19 area, WCDD002 to TD 41.6 m at the Worumba 20 area, and WCDD003 to TD 25.2 m at the Worumba 21 area. The recovered orientated HQ3 drill cores provided Taruga with structural and mineralogical insights into the sedimentary copper system at Wyacca, and revealed that there the ore - bearing zones are both dense and magnetic in comparison to the surrounding gangue rock. Fortuitously, the company's decision to acquire high resolution ground gravity and magnetic datasets across these zones has presented it with an excellent new exploration tool at Wyacca which was previously lacking, because the former reliance on using electrical geophysical methods to delineate ore zones had presented challenges of data interpretation, giving difficulty in separating the responses arising out of Tapley Hill Formation pyritic shales from those caused by copper sulphide - bearing ores. The Morgan Creek prospect RC drilling programme confirmed the inferred relationship of subsurface copper mineralisation to dolerite bodies, and showed that both are controlled by north-west trending structures. The dolerite is high in background copper (100 to 300 ppm Cu) and so it is the likely source for the historically worked surface copper occurrences and soil anomalism. However, it is documented in historical reports that there are observed instances of minor syngenetic copper being present within carbonates and pyritic shales, and because Taruga's drilling intersected 22 m @ 0.2% Cu in a sedimentary unit, it is now believed that there is significant potential for defining larger scale sedimentary copper mineralisation. Significant quantities of rare earth elements (REE) plus elevated silver, barium and scandium contents were encountered by the Morgan Creek RC drillholes. It therefore is thought that significant potential may exist for economic REE deposits to be associated with the diapric breccias within the Adelaide Fold Belt. Observations from Taruga's limited drilling indicate that the REE mineralisation is concentrated within metasediments around the margins of mafic intrusions which are the likely source of mineralisation. A subsequent review made of historic soil geochemical sampling results has found that much more extensive REE anomalism exists in the soil profile across the project area, so the potential for discovery of significant ionic clay - hosted REE mineralisation in the local regolith is considered high. An occurrence of skarn style alteration was discovered by the last-drilled Morgan Creek diamond drillhole MCDD004, which encountered mafic and ultramafic rocks carrying visible trace chalcopyrite mineralisation, which have been subjected to magnetite, epidote, serpentinite, calcite, chlorite and biotite alteration. At the Oxide Hill prospect, a low grade zinc occurrence was encountered within a dolomite/siderite unit, and is accompanied by elevated lithium. It is inferred that this occurrence may have been formed by a Mississippi Valley type (MVT) mineralising process.
