Latest Open Pit Mining News

New Murchison Gold has added a maiden 21,000-ounce Ore Reserve at Cloudkicker while reporting a group Mineral Resource of 353,700 ounces. The update also places 150,400 ounces of underground resources beneath Crown Prince, but the reserve base remains relatively short-dated and dependent on continued drilling and operating performance.

Broken Hill Gold has completed the transfer of its North Queensland exploration portfolio to Manda Resources, setting up a separate vehicle for the assets and a potential in-specie share distribution to BH6 holders. The company will now concentrate on White Dam in South Australia, although shareholder approval and the final Manda IPO structure are still pending.

OzAurum Resources has shifted Mulgabbie North from feasibility work into early construction, backed by encouraging laboratory heap leach results and a $4.10 million placement. But the company remains loss-making, cash-burning and dependent on further funding, with its auditor flagging a material uncertainty over going concern.

Meeka Metals has reported its first full-year profit as a gold producer, but the $51.3 million result came after a difficult second half and $107 million of growth investment. The company is now betting that higher-grade underground ore, processing upgrades and a fresh Mt Holland portfolio can improve cash generation.

Sunshine Metals has upgraded the economics of its Liontown project, forecasting A$179.8 million in net operating cashflow after capital over a 66-month mine life. The study points to mid-2027 mining, but depends on approvals, Mt Moss commissioning and a preliminary plan carrying a plus or minus 30% accuracy range.

Lefroy Exploration is considering folding the high-grade portion of its Burns deposit into the Mt Martin Scoping Study, broadening the development case while pushing delivery into the December quarter. At Lucky Strike, a newly granted licence removes one hurdle but several approvals still stand between the mine and a targeted early 2027 restart.

Tesoro Gold has established a maiden 1.28 million-ounce JORC Ore Reserve at Ternera in Chile, entirely within a single open pit. The reserve gives the El Zorro project a 13-plus-year production base, but the next test is funding and permitting a development still at PFS stage.

Antipa Minerals has expanded its Minyari Project resource to 3.6 million ounces of gold equivalent and advanced key pre-feasibility work, including conventional processing and deeper open-pit studies. The progress comes with an auditor-highlighted going-concern uncertainty as the company prepares for further exploration and development spending.

Arrow Minerals has applied for an iron ore exploration tenement adjoining Rio Tinto's Robe Valley operations in Western Australia, a move that could expand its prospective landholding by 30% to 415 square kilometres. The application remains subject to tenure award, and no resource or economic estimate has been announced.

Meeka Metals has lifted its group Mineral Resource to approximately 1.5 million ounces after adding a maiden 270koz estimate for Mt Holland in Western Australia. The expansion comes with a sharper distinction between exploration potential and mine-ready inventory, as Ore Reserves fell to 355koz after depletion and portfolio changes.

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.

Brightstar Resources will pay A$350,000 for five Panther Metals exploration licences beside its Laverton processing plant, securing ground needed for haul roads, water infrastructure and future tailings capacity. A separate, non-binding deal could also bring Panther’s Burtville East ore through the plant under a 50:50 net proceeds arrangement.
