Latest Reverse Circulation Drilling News

BOA Resources has extended the interpreted copper mineralised trend at Rooneys beyond 500 metres, with shallow high-grade intersections supporting a larger follow-up drilling campaign. The results add another exploration thread to the company’s expanding Neds Creek project, although continuity and true widths remain untested.

Terra Metals has reported broad PGM-copper-nickel intersections beginning at or near surface at its Southwest discovery in Western Australia. The results strengthen the geological continuity case ahead of a maiden Mineral Resource Estimate targeted for Q1 2027, although true widths, recoveries and final resource scale remain unconfirmed.

Tasman Resources has received South Australian approval for its Parkinson Dam environmental programme, clearing the regulatory path for a 20-hole drilling campaign. The programme now hinges on contractor appointments and a drilling start date, with historical high-grade gold and silver results providing the geological rationale.

Legend Mining is preparing to test its Pyrophyllite Hill gold prospect with a 50-hole aircore program after completing heritage surveys. The explorer ended September with $9.24 million in cash, although the reported 19.5-quarter funding estimate is based on a relatively modest quarter of spending.

Astral Resources has intersected broad, high-grade gold below the current Theia resource pit shell while extending mineralisation about 150 metres south. The results strengthen the exploration case beneath the planned open pit, although a resource or reserve increase has not yet been announced.

Piche Resources has extended the mapped footprint of its Cerro Chacón epithermal system in Argentina, with surface rock-chip samples returning up to 10.41 g/t gold and 553.42 g/t silver. The results support continuity between La Javiela and Toro Hosco, but drilling is still needed to test grade continuity at depth.

Caspin Resources has increased the Kelpie Deposit’s contained tin resource by 45% to 28kt, with the entire 6.5Mt estimate constrained within an optimised open-pit shell. The upgrade adds a maiden Indicated component, but most of the resource remains Inferred and no Ore Reserve has yet been declared.

Kalgoorlie Gold Mining has secured the full A$1.14 million targeted through its underwritten entitlement offer, despite eligible shareholders subscribing for only A$314,170. The capital is earmarked for drilling at the Lighthorse discovery, aircore work at LTZ Flexure and working capital.

Astral Resources has more than doubled the Spargoville project’s mineral resource to 281,000 ounces after reinterpreting four deposits and applying a larger optimised pit shell. The update lifts the group’s reported mineral resource to 2.21 million ounces, but remains a resource estimate rather than an ore reserve or production declaration.

Tennant Minerals has begun a multi-stage diamond drilling campaign targeting extensions and possible repetitions of its high-grade Bluebird copper-gold-bismuth discovery. The program tests an interpreted 1.5km structural corridor, but the Warrego-scale comparison remains an exploration target rather than an estimate of mineralisation.

Daly Resources has emerged from its June ASX debut with $11.05 million in cash, a 6,500 km² Northern Territory exploration portfolio and a growing list of drill targets. The catch is familiar for early-stage explorers: the company has yet to define a mineral resource or reserve, while its strongest Huckitta results remain surface sampling rather than drilling.

Tyranna Resources has identified high-grade surface anomalies at its Coola project in Angola, including soil assays of up to 13.18% TREO and 3.9% Nb₂O₅. The results refine drill targets ahead of a maiden program planned for the second quarter of 2027, subject to wet-season conditions.
