Latest Mineral Reserves News

Osmond Resources has secured the maximum €250,000 provisional grant in the first round of Spain’s national mineral exploration program, while preparing to start a 13-hole campaign at its Orión project. The company has also issued 85 million shares to retain its 80% interest in the project-owning vehicle.

Pursuit Minerals posted an A$666,579 FY2026 profit, but the result was driven largely by a fair-value gain on its Kendrick Resources investment rather than operating revenue. The company’s more consequential development is in Argentina, where Rio Grande Sur now carries a 1.264 million tonne LCE resource, a maiden probable reserve and a pre-feasibility case for 5,000 tonnes per year of lithium carbonate.

Larvotto Resources has extended high-grade antimony-gold-tungsten mineralisation at Clarks Gully about 100 metres beyond its 2025 resource model, with drilling also identifying several hanging-wall lodes. The results could support a larger resource and a potential underground feed source for Hillgrove, but assays, modelling and permitting work remain outstanding.

Mithril Silver and Gold has lifted the higher-confidence portion of its Copalquin Target 1 resource to 464,000 ounces of gold equivalent, giving the Mexican project a stronger base for mine planning. The upgrade comes alongside a larger loss, substantial exploration spending and an auditor’s warning that further funding is needed to support the company’s going-concern status.

Deterra Royalties has paid US$74.15 million for a royalty covering most of Ivanhoe Electric’s Santa Cruz copper project in Arizona. The deal adds a third core asset, but its projected returns still depend on financing, permitting and a targeted 2029 production start.

Peninsula Energy has increased the reported uranium resource at its Lance Project in Wyoming to 59.0 million pounds, with the Ross area delivering the clearest gain. The update adds confidence around Mine Unit 4, but remains a mineral resource estimate rather than a reserve or production forecast.

Stellar Resources has lifted its Heemskirk tin resource to 115.3kt of contained tin while technical studies move toward a prefeasibility study outcome. The company is better funded, but remains pre-revenue and faces the usual capital, permitting and execution hurdles of mine development.

Iron Bear Resources says a new federal-provincial assessment framework, major Labrador clean-energy investment and strategic-project coordination could improve the development pathway for its Canadian iron ore project. The initiatives are supportive, but they do not yet represent project approvals, secured power or construction funding.

Carnavale Resources is approaching the final stretch of its bankable feasibility study for the 80%-owned Kookynie Gold Project, backed by a 120,000-ounce resource and strong metallurgical recoveries. The project still requires financing, a toll-treatment agreement and final economic modelling before it can move from promising study to mine development.

Orezone Gold has outlined a 14-year plan for its newly acquired Casa Berardi mine, targeting 1.63 million ounces of production and an after-tax NPV of US$1.05 billion. The economics are substantial, but the plan remains a preliminary assessment built partly on Inferred Resources and requires significant capital and permitting work.

Alcoa has filed South32’s meeting materials ahead of a shareholder vote on the proposed sale of bauxite, alumina and aluminium interests. The transaction remains subject to shareholder approval, regulatory clearance, financing and other closing conditions.

Pan African Resources has completed a definitive feasibility study for a ZAR3.68 billion Soweto tailings project with a projected 29.55% real ungeared IRR. The proposed operation could add up to 40,000 ounces of annual gold production, but financing, permits and board approval remain ahead of a targeted December 2026 investment decision.
