Latest Copper Gold Exploration News

Centaurus Metals has identified more than 20 drill-ready copper-gold targets across its expanded 75km² Boi Novo Project in Brazil. The pipeline includes eight priority prospects at Rio Novo and 13 additional targets at the original Boi Novo tenure, but the results remain an exploration story rather than a new discovery or resource estimate.

Eagle Mountain Mining has emerged from FY2026 with no borrowings, a A$7.27 million accounting profit and a funded 20% interest in its Oracle Ridge copper project. The next test is whether Nittetsu’s drilling and earn-in spending can add value to an asset whose mineral resource has not changed since 2023.

Sierra Nevada Gold has started a 25,000-metre second-phase drilling campaign at its As Safra copper-gold project in Saudi Arabia, with the first assay results due in November. The company is directing capital and management attention to Saudi Arabia while exploring commercial options for its Nevada portfolio.

FMR Resources has completed planning for at least 2,000 metres of drilling at La Lorena and identified five new intrusive targets in an eastern structural corridor. The Chile-focused explorer also exercised its Los Warbos option after quarter end, but reported cash of A$3.786 million and an estimated 2.51 quarters of funding at the September quarter’s spending rate.

Sabre Resources has completed its maiden 4,362-metre drilling program at Kurundi North, where surface sampling identified copper, bismuth, silver, zinc and lead associated with ironstone. The key test now moves to the laboratory, with 1,048 drill samples awaiting results expected in four to five weeks.

Zeus Resources has secured a 51% interest in the Diaguili copper-gold project in Mauritania and assumed management after completing the first tranche of its acquisition. Drilling is expected to begin during the current quarter, giving the company a near-term test of the project’s exploration case.

Hot Chili has confirmed a second porphyry centre south of its La Verde copper-gold discovery in Chile, with RC drilling returning a broad, shallow copper intersection. A deeper diamond hole shows extensive sulphide mineralisation visually, but laboratory assays are still required before the scale can be properly assessed.

Solstice Minerals has reported broad copper-gold intersections beyond Nanadie’s current resource boundary, including 64.1 metres at 0.94% copper and 91.4 metres at 0.97% copper. A spectacular silver interval adds intrigue, but its geometry and economic significance remain unresolved.

Hot Chili has reported broad, shallow copper-gold intersections at La Verde, including 188 metres at 0.56% CuEq and 240 metres at 0.43% CuEq. The results strengthen the geological case for a near-surface mining zone, but the discovery still has no Mineral Resource and 25 drillholes await assays.

Tennant Minerals has reported a high-grade maiden resource and further strong drilling at its Bluebird copper-gold discovery, but the annual report carries a material uncertainty over the company’s ability to continue as a going concern. A $2.8 million capital raise completed around year-end provides near-term funding, while further exploration and processing studies remain ahead.

Solstice Minerals has extended the Nanadie copper-gold system to at least 1.5km of strike, with deep diamond drilling returning broad mineralisation beyond the current resource boundary. The results include a 169.3m intercept at 0.87% copper and 0.29g/t gold, while more than 40 holes remain awaiting assays.

Breakthrough Minerals has shifted its centre of gravity to a 952-square-kilometre Queensland copper-gold portfolio, backed by an 18.8Mt JORC resource and early drilling success. The annual report also highlights the constraint: a A$5.69 million loss, ongoing cash burn and material uncertainty over future funding.
