Latest Feasibility Study News

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.

St Barbara will sell its remaining New Simberi interest and Tabar Islands exploration exposure to Lingbao for A$453 million in cash, while retaining royalties over future production. The deal could leave the gold developer with about A$880 million in cash, but completion still depends on regulatory and potentially shareholder approvals.

Ariana Resources has reported broad and high-grade gold intercepts from metallurgical and exploration drilling at its Dokwe project in Zimbabwe. The company has now shipped eight tonnes of samples to China for feasibility-level metallurgical testwork, while further drilling and DFS work remain ahead.

Viridis Mining and Minerals has selected Sedgman and Blossom as the preferred EPCM partner for its Colossus rare earths project, with up to US$3 million approved for work before a final investment decision. The full contract remains conditional, but engineering and procurement activity will begin immediately.

Tungsten Mining has secured the primary approvals needed to take its Watershed tungsten project in Far North Queensland through to mining and production, while early site works are already under way. The project remains pre-FID, with financing and the October DFS still critical to the H1 2027 production target.

Maronan Metals has intersected repeated copper-gold zones north of its 2025 Indicated resource at the Maronan Project, including a 20-metre interval grading 0.83% copper and 0.42g/t gold. The results support ongoing resource growth work, but further drilling and assays are needed before any resource change can be established.

Sovereign Metals says a simple add-on circuit at its Malawi project could generate US$722 million of pre-tax value from monazite by-product recovery. The opportunity is commercially striking, but remains a preliminary scoping result dependent on further testwork, approvals, funding and customer qualification.

Rox Resources has increased Youanmi’s Ore Reserve by 8% to 727,000 ounces after mining depletion, while the broader Mineral Resource edged up to 2.195 million ounces. The update excludes results from recent surface and underground drilling programs, leaving future revisions as a potential source of change.

Rua Gold has reported its highest-grade Auld Creek drilling results to date, including 0.6 metres at 136.2 g/t gold equivalent and 2.9 metres at 38.8 g/t gold equivalent. The company has completed 19,600 metres of resource drilling and is targeting an updated resource, approvals application and pre-feasibility study before year-end.

Astral Resources has reported a 1.54g/t Au weighted average across 41 infill holes at Theia, including several high-grade intervals that exceed the existing Stage 1 resource grade. A separate deviated hole returned 1m at 219g/t Au, adding further support to the early mining inventory while deeper drilling continues.

Encore Minerals has approved development of the Windarra Tailings Project, triggering a $400,000 payment to Maritana Minerals and preserving the company’s exposure to future gold production through royalties. Encore will carry the project’s development and operating costs, although key execution milestones remain ahead.

Sunrise Energy Metals has put its Syerston scandium project on a stronger financial footing, ending FY2026 with A$115.4 million in cash and a conditional US$400 million debt commitment. The project still faces a decisive sequence of tests: final investment approval, binding offtake agreements, financing conditions and construction execution.
