Latest Heap Leach News

TG Metals has strengthened its gold and lithium resource base, but the annual report carries a material uncertainty over its ability to continue as a going concern. The company ended June with $641,906 in cash, before securing a further $2.5 million placement after year end.

Broken Hill Gold has lifted the Vertigo deposit’s Indicated oxide resource by 160% and increased White Dam’s global resource to 118,496 ounces. The company is now testing whether shallow material can support a heap-leach restart while drilling deeper gold-copper sulphide potential.

Red Metal’s Sybella project has moved closer to a development decision after heap-leach testing delivered strong rare earth extractions with low impurity levels. The company also reported a $19.17 million FY2026 profit, although most of that result came from the accounting gain tied to its Maronan Metals restructuring.

Trek Metals has secured a nine-month option to acquire the 154-claim Matrix Manganese Project in Arizona for a total potential cash consideration of A$200,000. The deal offers a low-cost route into a US critical-minerals opportunity, but carries a significant related-party consideration because CEO Derek Marshall owns about 66.67% of the vendor.

Cyprium Metals has begun acid commissioning at its Nifty heap leach pads for the first time since 2009, bringing its copper restart into the operational phase. The company now expects first cathode production in the fourth quarter of 2026, subject to energisation, wet commissioning and ramp-up.

Australian Rare Earths has moved its Koppamurra pilot plant beyond heap leaching, recovering rare earths from about 5,000 litres of leach solution into a Mixed Rare Earth Hydroxide intermediate product. The result provides an early test of the downstream flowsheet, although commercial economics and final product quality remain unproven.

Bannerman Energy has completed a fully underwritten A$124 million institutional placement, giving the Etango uranium project a funding pathway through construction and ramp-up. The company now turns to a targeted Q4 2026 Final Investment Decision, while a further non-underwritten shareholder offer could raise up to A$10 million.

Challenger Gold has set early 2029 as the target for commercial production from a stand-alone heap leach operation at its Hualilán project in Argentina. The roadmap brings engineering, drilling and financing into sharper focus, but still depends on a US$15 million debenture refinancing and a much larger project funding package.

Great Northern Minerals (ASX: GNM) reported a $3.8 million loss for FY26 amid major US acquisitions, including the Iron Butte gold-silver project with a maiden resource of 480,000 oz gold and 11.5 million oz silver, and the Catalyst Ridge rare earths project. The company also completed a $2 million divestment of its remaining Golden Ant interest.

Anax Metals is upgrading its Whim Creek Heap Leach Scoping Study to a Feasibility Study, aiming to unlock additional value from low-grade copper and zinc ores alongside its strong concentrator project.

Austral Resources Australia Ltd has swung from a $24.2 million loss to a $25.3 million profit in the first half of 2026, boosted by strategic acquisitions, capital raises, and operational shifts. The company is advancing its Rocklands restart and has proposed acquiring Hammer Metals to expand its copper footprint.

Black Bear Minerals (ASX: BKB) has raised $12.5 million through a placement at a 16% discount to fund underground drilling and resource validation at its Shafter Silver Project in Texas, signaling strong institutional support for advancing mine restart plans.
