Latest Open Pit Mining News

Horseshoe Metals has outlined a substantially larger conceptual open pit at Horseshoe Lights, containing 95,033 tonnes of copper under a A$25,000-per-tonne price assumption. The result supports further studies, but does not yet establish an Ore Reserve or a development case.

PMET Resources has increased contained caesium oxide at its Shaakichiuwaanaan project by 55% and added maiden rubidium and CV4 lithium resources. The update is designed to feed an updated feasibility study and broader economic assessment due before year end, but the new resources are not yet reserves.

Orezone Gold has put a US$1.05 billion after-tax valuation on a 14-year Casa Berardi mine plan, with a planned East Mine restart and 1.63 million ounces of production. The economic case remains preliminary, includes Inferred Resources and reports no Mineral Reserves.

Zimplats will replace long-serving chief executive Alexander Mhembere with internal successor Dr Stanley Segula from 1 November. The handover preserves operational continuity while Mhembere remains chairman of the company’s Zimbabwean operating subsidiary.

Focus Minerals generated A$180.1 million in customer receipts during the September quarter, while Bonnie Vale underground production rose alongside stable processing at Coolgardie. The company finished with A$184.6 million in cash, a A$95.1 million term deposit and a fully franked dividend paid to shareholders.

Pivotal Metals has put a A$920 million post-tax NPV on its Horden Lake copper project, while continued drilling and target generation broaden the company’s Quebec growth story. The attraction comes with familiar development-stage caveats: the study is preliminary, includes inferred material and leaves Pivotal with about 2.4 quarters of funding at the reported spending rate.

Caravel Minerals has completed the mining component of its Caravel Copper Project feasibility study, but the full DFS has slipped into the fourth quarter of 2026. The company is also reviewing process plant costs while holding $16.8 million in cash and reporting an estimated 4.6 quarters of funding at the quarter’s outflow rate.

Kingston Resources has reported high-grade polymetallic drilling results across Mineral Hill while advancing a 25,000-metre FY27 campaign and planning resource and reserve updates. The company ended September with A$14.54 million in cash and no debt, but the mine remains on care and maintenance and its strategic review has no guaranteed outcome.

Victory Metals has put a A$1.21 billion post-tax PFS value on North Stanmore, secured its mining lease and begun product qualification with potential offtake partners. The project remains pre-production, with DFS work, approvals, financing and metallurgical validation still ahead.

St George Mining’s Araxá project advanced on several fronts in the September quarter, with a 155% increase in Measured and Indicated resources, new high-grade drilling and environmental permitting underway. The company ended the period with A$86.2 million in cash, but still has to convert a large Mineral Resource into an economically viable operation.

Western Gold Resources has lifted Gold Duke’s Production Target by 62% to 59.7koz of contained gold, strengthening the project’s development case. But the company still needs a processing solution and reports only about 1.56 quarters of funding on current outgoings.

Killi Resources has extended its Lodestone magnetite system beyond the existing 110Mt Inferred Resource, with step-out drilling intersecting broad visual zones south of the resource boundary. The company ended September with A$16.4 million in cash as a second rig and a high-resolution magnetic survey moved the project into its next phase.
