Latest Heap Leaching News

Austral Resources has extended the known McLeod Hill copper system to more than 1km of strike, well beyond its existing 470m Mineral Resource footprint. The shallow mineralisation sits within existing mining leases and 4.5km of the company’s Western Operations processing facility, but still requires further drilling, modelling and metallurgical work.

Cyprium Metals says direct-injection heap leaching at its Nifty Copper Complex has reached target injection rates, with 212 wells now established across Pad 6. The company remains on track for wet commissioning and first copper cathode production in Q4 2026, although the reported chemistry is still based on early commissioning results.

Alvo Minerals has secured A$1 million from strategic and existing investors while reporting broad, near-surface dysprosium and terbium mineralisation at its Bluebush project in Brazil. The results strengthen the exploration story, but metallurgy, permeability and a maiden resource remain ahead.

Kingsgate Consolidated has converted a full year of Chatree mining into record financial results, with revenue up 77% and net profit reaching A$277.9 million. The balance sheet is stronger, dividends have returned and Nueva Esperanza is moving towards a feasibility decision, but higher waste movement and project execution now replace the turnaround story.

Broken Hill Gold has recast itself from explorer to South Australian gold operator, producing its first doré while uncovering a deeper gold-copper sulphide system at White Dam. The transformation came with a $14.46 million FY2026 loss and continuing reliance on capital markets.

Rimfire Pacific Mining has expanded its NSW scandium inventory and reported preliminary leach results that could support a simpler extraction route. But the ASX explorer ended FY2026 with $583,770 in cash, negative working capital and an auditor-highlighted material uncertainty over its ability to continue as a going concern.

Felix Gold advanced bulk extraction, processing and refinery plans at its Alaska antimony project in FY26, but the push came with a larger loss, falling cash and an auditor-documented material uncertainty over going concern. A potential US$18 million Department of Energy award remains subject to negotiation rather than a committed funding source.

Cyprium Metals says its long-delayed Nifty Copper Complex is entering the final commissioning phase, with first copper cathode production expected in the December quarter of 2026. The restart is backed by A$121 million in equity raisings, a refinanced US$27.3 million loan facility and A$68.5 million in cash at year-end.

Norwest Minerals has strengthened the technical case for its Bulgera heap-leach project with a revised 191,000-ounce resource and 86% bottle-roll recoveries. But the ASX-listed explorer ended FY2026 with $394,541 in cash, and its auditor highlighted material uncertainty over its ability to continue as a going concern.

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.
