Latest Pre Feasibility Studies News

Kalamazoo Resources is moving Ashburton from exploration story to development proposition, backed by a positive Mt Olympus Scoping Study and extensive drilling. The next test is whether the updated resource, feasibility work and funding can turn the project’s preliminary economics into a mineable plan.

Tivan has secured the regulatory and cultural heritage clearances needed to advance an 8,000-metre drilling campaign at its Molyhil tungsten project in the Northern Territory. The company will also issue 3.84 million shares as part-payment for the project acquisition, while its feasibility and proposed funding plans remain unfinished.

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.

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.

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.

Brazilian Rare Earths has commissioned its Stage I beneficiation pilot plant in Bahia and produced its first rare earth mineral concentrate. Partners will contribute R$6.4 million, or about A$1.7 million, towards the next hydrometallurgical stage planned for commissioning in Q2 2027.

Barton Gold has secured approval for the environmental scope governing development studies at its Tunkillia gold and silver project in South Australia. The milestone moves the project towards a Mining Lease application, with updated resources, Ore Reserves and a pre-feasibility study targeted for the first quarter of 2027.

Hot Chili has reported a 398-metre copper-gold intersection from surface at its La Verde discovery in Chile, including 62 metres at 0.91% CuEq. The results extend the case for a higher-grade starter pit, but the project remains an exploration discovery with no Mineral Resource declared.

Impact Minerals’ 50%-owned Alluminous project reveals a strong financial case for a staged US high purity alumina plant, projecting a post-tax NPV₈ of A$518 million and a 42.3% IRR under a modular development approach.
