Indiana Resources Limited (ASX: IDA) has announced more high-grade results from assaying of the final five RC drill holes recently completed at the Minos Prospect within its Central Gawler Craton Gold Project in South Australia.
Significant high-grade results included 38m @ 6.54 g/t Au from 29m in Hole LLRC029 including 16m @ 13.12 g/t Au from 37m; 2m @ 6.32 g/t Au from 100m in Hole LLRC029; and 26m @ 4.28 g/t Au from 68m in Hole LLRC025 including 3 m @ 20.21 g/t Au from 82m. The company said that the results confirm high grades of mineralisation.
The company said that follow-up RC drilling is being planned, including potential diamond tail extensions of existing RC holes.
Exploration programme at Central Gawler project
The company had commenced drill programme at known prospects within Indiana’s 100% owned 5,090 km2 Central Gawler Craton Gold Project landholding.
Previous significant drilling intercepts from regional targets included Ariadne – 6m @ 4.05 g/t Au, 11m @ 2.44 g/t Au, 12m @ 1.18 g/t Au; Earea Dam – 4m @ 10.2 g/t Au, 3m @ 13.8 g/t Au; Boomerang – 4m @ 5.44 g/t Au, 2.0m @ 10.5 g/t Au; and Double Dutch – 34m @ 1.18 g/t Au, 18m @ 1.07 g/t Au, 25m @ 1.25 g/t Au.
RC drilling at Minos
The Minos prospect is located within the Lake Labyrinth Shear Zone (LLSZ) and is interpreted to be a 30km long WNW- ESE trending regional structure that is at least 50 to 100 metres wide.
The company said that Minos is the first of several highly prospective targets within IDA’s portfolio to be drill tested as part of a large-scale exploration programme. The programme was designed to test a 600m long section in the core of the Minos target.
The company said that 10 RC drill holes were completed varying in depth from 72m to 210m for a total of 1,596m drilled.
Encouraging assays from the first 5 RC holes
The first 5 holes (LLRC020 – 024) of the Minos RC drilling programme had returned high-grade assays. Significant results included LLRC020 – 19m @ 2.88 g/t Au from 78m, including 1m @ 10.6 g/t Au from 92m; 5m @ 24.35 g/t Au from 106m, including 2m @ 59 g/t Au from 106m; 22m @ 3.07 g/t Au from 125m, including 1m @ 21.5 g/t Au from 137m, 1m @ 23.0 g/t Au from 142m; and 3m @ 18.33 g/t Au from 189m, including 1m @ 42.1 g/t Au from 190m; and LLRC021 – 8m @ 4.79 g/t Au from 89m including, 2m @ 13.9 g/t Au from 89m.
High-grade assays from the final 5 RC holes
The company announced that further high-grade results were received from assaying of the remaining five Reverse Circulation (RC) drill holes (LLRC025 – 029) recently completed at the Minos Prospect. The company said that two of the holes (LLRC027- 028) were drilled as pre-collars to planned diamond drilling.
Significant high-grade results included 38m @ 6.54 g/t Au from 29m in Hole LLRC029 including 16m @ 13.12 g/t Au from 37m; 2m @ 6.32 g/t Au from 100m in Hole LLRC029; and 26m @ 4.28 g/t Au from 68m in Hole LLRC025 including 3 m @ 20.21 g/t Au from 82m.
New significant Au intercepts are as shown below.
IDA said that nine of the ten holes drilled for the programme ended in the mineralised shear zone and the Minos prospect appears to be open along strike and at depth.
Updates and next steps
Indiana said that it is planning to comprehensively review these results as the basis for planning future exploration activity including follow up RC and Diamond Drilling. The company said that this may include a mix of RC drilling at known prospects within Indiana’s Central Gawler Craton landholding, including Ariadne, Company Well, North Hicks, and Partridge, to expand the current zones of mineralisation.
Indiana’s Executive Chairman Bronwyn Barnes said: “Our 2021 exploration campaign is off to a brilliant start and these exceptional results from Indiana’s maiden drilling programme confirm the excellent prospectivity of our ground position in the Gawler Craton.
These high-grade intersections, and broad widths of mineralisation, have exceeded our initial expectations and we are now moving quickly to finalise our follow up RC and Diamond drilling programmes for the next two months. This is an exciting time for Indiana, and we look forward to ramping up our work programmes over the coming months at several key targets within our Gawler Craton portfolio.”
