Latest Heap Leaching News

Anax Metals has moved its Whim Creek copper-zinc project deeper into engineering and financing work, while Mons Cupri’s Mineral Resource rises 24% to 6.32 million tonnes. The company is still targeting a fourth-quarter Final Investment Decision, but funding remains non-binding and the larger resource has yet to enter the project’s Ore Reserve or financial forecasts.

Turaco Gold has reported high-grade gold extensions at Begnopan and Asupiri-Adiopan, including a 6-metre hit at 18.52g/t, as it prepares to update Afema’s 4.65Moz Mineral Resource. The results remain exploration data rather than a new resource or reserve, but several intersections sit beyond existing models and Ore Reserve boundaries.

Red Metal’s latest column tests have extended the heap-leach case to the largest ore type at its Sybella rare earth project, with 65% neodymium and 68% praseodymium extraction from fresh granite. The result brings 598 million tonnes of fresh granite into the company’s pre-feasibility study, although the ore requires a longer leach cycle than its weathered counterparts.

Flagship Minerals has extended its Rosario Copper Project option by one year and cut the final exercise payment from US$2 million to US$1 million. The revised terms give the company more time to advance Isidora before committing further exploration capital to Rosario.

Bannerman Energy and CNNC Overseas have approved the Final Investment Decision for the Etango uranium project in Namibia, clearing the way for full-scale construction and targeting first yellowcake in 2028. The project is forecast to produce about 3.5 million pounds of U3O8 annually, with construction funding described as covered by existing cash balances.

Stavely Minerals has paired strong preliminary economics for its Thursday’s Gossan copper-gold-silver project with a much tighter near-term funding position. The company also reported higher-grade mineralisation at depth at the Freddy’s Find gold-silver prospect.

OD6 Metals has converted a run of high-grade Nevada fluorspar discoveries into a proposed 10,000-metre maiden drilling and bulk-sampling campaign. The company ended September with A$1.775 million in cash, but a subsequent A$6.92 million placement lifted pro forma funds to about A$8.695 million before costs and later movements.

Trek Metals has confirmed a shallow, high-grade manganese discovery at Kuro in Western Australia, with 38 of 72 Phase 1 holes returning significant intercepts. Follow-up drilling is complete, while the company has also secured an option over a second manganese project in Arizona.

Silver Mines has begun its first modern drilling program at the Kramer Hills gold project in California, targeting shallow oxide mineralisation and possible deeper sulphide zones. The 22-hole campaign will test a conceptual exploration target of up to 445,000 ounces, but the project remains well short of a JORC Mineral Resource.

TG Metals has advanced its Van Uden gold development and Lake Johnston lithium project, including a high-return heap-leach study and a maiden 6.71Mt lithium resource. But the ASX explorer ended September with A$1.523 million in cash, equivalent to just 1.05 quarters of funding at the reported spending rate.

Norwest Minerals has strengthened the technical case for its Bulgera heap-leach project, but its annual report highlights a sharper near-term constraint: just A$394,541 in cash at 30 June and material uncertainty over its ability to continue as a going concern. The company subsequently raised about A$1.89 million through an entitlement offer.

Stavely Minerals is testing smaller and potentially easier-to-fund development routes for Thursday’s Gossan after a large open-pit study delivered strong economics but demanded substantial upfront capital. The alternatives could reduce capital intensity, although the company expects they may produce lower NPVs.
