Latest Underground Mining News

Rox Resources has crossed the line from explorer to mine developer, with Youanmi underground mining underway, the processing plant under construction and a target of first gold in mid-2027. The project is financed on paper, but the A$350 million debt package remains subject to conditions precedent and the construction schedule still has to survive execution.

Orion Minerals has set out a clearer route towards first production at its Prieska copper-zinc project, but its audited FY2026 accounts warn that further funding remains essential. The company reported a A$12.69 million loss and A$14.46 million in cash while targeting first production in Q3 2027.

PC Gold has identified a historically sampled high-grade domain at Spring Hill, with a composite 20.35m channel result grading 13.04g/t gold outside the current resource estimate. The target has not been drilled, leaving continuity and true width unresolved ahead of planned testing in late September.

Tolu Minerals has increased the Tolukuma gold resource by 81% to 909,000 ounces after four months of full-scale drilling, pushing its reported Papua New Guinea gold inventory above one million ounces. The proposed early 2027 restart now has a larger resource base, but remains dependent on infrastructure, technical work and conversion of resources into mineable reserves.

Pantoro Gold has extended the interpreted mineralised strike at its Racetrack discovery to about 900 metres, with drilling returning several high-grade intersections. The company will begin a 450-metre exploration decline from the OK Underground Mine in the December 2026 quarter, although Racetrack remains outside the current Mineral Resource and Ore Reserve.

Evolution Mining has set out a capital-heavy FY27 strategy, combining a record fully franked 41 cents per share dividend with major spending across Cowal, Northparkes and Ernest Henry. The miner also plans to lift exploration and maintain gold and copper guidance, though much of the production upside remains several years away.

New Hope delivered more coal, expanded its resource base and declared a 30-cent final dividend, but lower realised prices and higher costs cut FY26 profit by 63.4%. The results leave investors weighing near-term earnings pressure against a larger production pipeline.

Catalyst Metals has increased the Trident underground Ore Reserve by 32% to 524,000 ounces, supporting a planned mine life of more than 10 years. The result strengthens the company’s ambition to build a 2Moz Reserve base across the Plutonic Belt, although further growth depends on drilling and mine execution.

Gorilla Gold Mines has lifted its reported Mineral Resource to approximately 2.0Moz of gold after a year of intensive Western Australian drilling. The gain comes with strong exploration momentum, but the company remains pre-revenue and expects to seek further funding.

BMC Minerals has moved the Kudz Ze Kayah project through a key regulatory gateway and reported high-grade drilling beyond the current reserve, but its first full year as an ASX-listed company also exposed the funding challenge ahead. The Canadian developer ended FY2026 with US$50.3 million in cash, no revenue and an auditor-highlighted material uncertainty over going concern.

Green Technology Metals has completed the environmental assessment for its Seymour Lithium Project in Ontario, removing a major step from the mine’s permitting pathway. The milestone does not yet amount to final development approval, with a mine closure plan and several permits still required.

Latitude 66’s KSB project has returned a striking preliminary economic case, with a post-tax NPV8 of US$485 million and an 85% IRR at a US$3,500 per ounce gold price. The opportunity remains unbuilt, unfunded and subject to further study, permitting and a production target containing 10% Inferred Resources.
