Renascor Resources identified multiple copper prospects from a historical drilling review at Flat Hill. The company plans re-assays and a VTEM survey to test for a large mineralised system.
Renascor Resources (ASX: RNU) has identified multiple copper prospects from a review of historical drilling at the Flat Hill project in South Australia. The company said the work supports potential for a large-scale mineralised system spreading well beyond localised targets.
The review showed copper mineralisation is widespread across the project, not confined to a single zone. Anomalous grades appear over several kilometres of strike within a 500 square kilometre area, Renascor reported.
Best historical assays came from the Breaden Hill and Boorloo targets, plus a zone at Breaden Hill South. One intercept ran 18 metres at 1.57% copper from surface, including 6 metres at 2.5%. Another returned 10 metres at 1.84% copper from 0.5 metres, with a 1.8-metre section grading 5.2%. The longest hit was 134 metres at 0.57% copper from 26 metres, including 28 metres at 1.11%.
Those results will now drive a fresh work program. Renascor plans a full inspection of historical drill holes, a multi-element re-assay of existing core and cuttings, and a high-resolution VTEM survey across the property to sharpen drill targets.
Managing director David Christensen said the company sees a chance to apply modern methods to an under-explored district. “The review has demonstrated that copper mineralisation is widespread across the Flat Hill area and not restricted to a single prospect or occurrence,” he said. “In our view, the scale and distribution of these occurrences support the potential for a larger mineralised system extending beyond the individual prospects identified to date.”
Christensen added that the re-assay program and geophysical work could help vector toward mineralised systems and assess the potential for associated metals, including gold, silver, lead, zinc, and cobalt.
Flat Hill has seen multiple exploration campaigns over decades, targeting sediment-hosted copper in the Adelaide Rift Complex. Past explorers found numerous copper occurrences, activity was fragmented because advanced techniques were not available to evaluate district-scale structural targets. Renascor now hopes that multi-element analysis will provide fresh geological and geochemical clues.
The company has not yet set a timeline for the VTEM survey or re-assays. The work program will determine when new drill targets are ready for testing.
