Latest Heap Leach News

West Cobar Metals ended FY2026 with more cash but a larger loss and an auditor-highlighted material uncertainty over its ability to continue without further funding. Exploration advanced across Salazar and Cobar West, but the company remains dependent on equity markets to keep its programmes moving.

TG Metals has outlined a preliminary A$26.8 million pre-tax NPV for a low-capital heap leach operation at its Van Uden Gold Project in Western Australia. The economics are striking, but the study remains an early-stage assessment reliant on further drilling, approvals, financing and technical work.

Revolver Resources has taken its Dianne Copper Mine Project from study towards construction readiness, with a larger resource, secured approvals and a forecast $125.7 million pre-tax cash flow. But the restart still depends on project-level funding before a Final Investment Decision can be made.

Alliance Nickel has approved a second phase of vat leach testing after preliminary NiWest results supported continued evaluation of the alternative processing route. The potential prize is substantial, but quantified recoveries and capital savings remain unproven.

Challenger Gold has locked in US$24 million through five-year unsecured convertible debentures to advance its Hualilán project, with a further US$6.3 million potentially available. The financing carries an 11% coupon and only part of the proceeds is unconditional, leaving shareholder approval and a much larger funding requirement ahead.

Australian Rare Earths has converted Koppamurra from an exploration story into a defined rare earths development case, with an A$858 million after-tax PFS NPV and a maiden Ore Reserve. The next test is less geological than financial: the company must fund the path from pilot processing to construction while carrying a material going-concern warning.

Cobalt Blue has cleared important technical and regulatory hurdles at its Kwinana refinery, but the pre-revenue developer says further funding is needed and auditors flagged material uncertainty over its ability to continue as a going concern. The company reported an A$8.797 million loss for FY2026 despite ending the year with A$4.265 million in cash.

Broken Hill Gold has completed the transfer of its North Queensland exploration portfolio to Manda Resources, setting up a separate vehicle for the assets and a potential in-specie share distribution to BH6 holders. The company will now concentrate on White Dam in South Australia, although shareholder approval and the final Manda IPO structure are still pending.

Cavalier Resources is advancing site preparation, contractor negotiations and recruitment at its Crawford Gold Project, but its financing remains unfinished after Javelin Global Commodities’ exclusivity period expired. Shareholders have also approved a A$60,000 share subscription by interim CEO Daniel Tuffin.

Anax Metals has moved its Whim Creek copper-zinc project closer to a targeted investment decision, backed by strong feasibility economics and new drilling. But the annual report makes clear that development still depends on securing further funding, with the auditor warning of a material uncertainty over going concern.

OD6 Metals has transformed its portfolio with the completed acquisition of Nevada’s Quinn Fluorspar Project, but the strategic expansion comes alongside a larger loss, ongoing funding needs and substantial permitting risk. The company is now targeting drilling and a maiden resource at Quinn while advancing laboratory-scale rare earth processing work at Splinter Rock.

OzAurum Resources has shifted Mulgabbie North from feasibility work into early construction, backed by encouraging laboratory heap leach results and a $4.10 million placement. But the company remains loss-making, cash-burning and dependent on further funding, with its auditor flagging a material uncertainty over going concern.
