Indiana Resources Limited (ASX: IDA) has received promising results from its auger calcrete geochemical sampling programme completed over prospective targets within the 100% owned 5,713 sq. km Central Gawler Craton Gold Project in South Australia.
The calcrete sampling programme has identified several new coherent gold-in-calcrete anomalies. Further sampling and drilling programmes are planned to test these geochemical anomalies as soon as statutory and heritage approvals are granted.
“We are highly encouraged by the coherent gold anomalism identified along the Lake Labyrinth Shear Zone at Ealbara and Partridge, with the shear hosting our broad, high-grade gold mineralisation at Minos,” Indiana’s Technical Director, Felicity Repacholi-Muir, said.
“The strong gold anomaly returned at Earea Dam is of particular interest, and further highlights the underlying potential over this region.
“Our exploration team is reviewing the geochemical anomalism and is now planning the next stage of exploration to test for mineralisation in the bedrock.”
Geochemical Programme
Calcrete sampling was completed during December 2021 at various locations across the Central Gawler Gold Project.
The programme comprised a total of approximately 900 samples, collected locally on a range of different sample grids, ranging from 40m x 40m to 400m x 400m sample spacing and was the first regional exploration programme undertaken to assess multiple underexplored target areas within the Central Gawler Craton Gold Project.
The aim of the calcrete sampling was to identify additional drill targets along the prospective structures. Samples were analysed for gold and additional pathfinder elements to identify mineralisation and aid lithological mapping.
Auger sampling targeting calcareous soils (calcrete) has been successfully employed as one of the preferred geochemical sampling mediums for gold exploration within the Gawler Craton for the past three decades and has been credited with several significant gold discoveries over the past three decades.
The Challenger Gold Mine was discovered by Dominion Mining Ltd and Resolute Ltd (Gawler Joint Venture) as the result of a regional calcrete sampling programme in 1995. Calcrete sampling has been attributed to the discoveries of various other gold prospects, including Tunkillia in 1994 and Marmota Limited’s recent success at Aurora Tank.
Completion of RC Drilling – Minos
Indiana successfully completed RC drilling at the Minos Prospect during April 2022. A total of 14 drillholes were completed for 1,868 metres.
The drilling focused on tightening the existing drill density within the central portion of known mineralisation, increasing the confidence levels to enable Indiana to deliver a maiden Resource.
Drilling to date has outlined a 600-metre strike extent of shallow, near-surface mineralisation. Previous significant results from Minos include:
• 38m @ 6.54 g/t Au from 29m in Hole LLRC029 including 16m @ 13.12 g/t Au from 37m
• 21m @ 8.43 g/t Au from 176m in Hole LLRC041 including 1m @ 159 g/t Au from 185m
• 23m @ 6.44 g/t Au from 186m in Hole LLRC035 including 1m @118 g/t Au from 198m
• 26m @ 4.28 g/t Au from 68m in Hole LLRC025 including 3m @ 20.21 g/t Au from 82m
• 36m @ 2.63 g/t Au from 124m in Hole LLRC069 including 1m @ 12.60 g/t Au from 151m and 1m @ 12.50 g/t Au from 159m
• 26m @ 3.58 g/t Au from 76m in Hole LLRCD028 including 2m @ 18.9 g/t Au from 92m
• 10m @ 8.83 g/t Au from 39m in Hole LLRC042 including 3m @ 26.03 g/t Au from 40m
The alteration observed in the April drillholes was consistent with planned intersections. Results are anticipated to be received later this quarter.
