Latest Resource Estimation 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.

Famien Resources will sell its West Yilgarn exploration portfolio to Voltaic Strategic Resources for $330,000 upfront, with a further $2 million tied to future gold resource milestones. The deal gives Famien immediate cash while leaving the larger deferred payment dependent on exploration success by the buyer.

Kalgoorlie Gold Mining has identified multiple coherent gold-in-regolith anomalies across the first 225-hole aircore test of its LTZ Flexure target at Pinjin. The strongest exploration signal stretches up to 2km, but primary gold mineralisation at depth remains unconfirmed.

Gold Mountain has secured a 12-month exclusive right to acquire the historical Malhada do Angico tungsten mine in northeast Brazil, for staged consideration of up to R$3 million. The opportunity comes with encouraging but non-representative grab samples, pending approvals and a drilling program still awaiting permits.

Vertex Minerals’ Reward Gold Mine produced 679 ounces in its first production year, but the transition came with a A$16.4 million loss, negative operating cash flow and a formal going-concern warning. The company now faces a narrow window to prove its mechanised mining plan can lift production before debt repayments and further funding decisions bite.

Xstate Resources has secured preferred tenderer status for a 305 square kilometre block in Queensland’s Taroom Trough, with the company set to initially operate a four-party joint venture. The prospective acreage offers exposure to basin-centred gas, associated liquids and light crude, but the licence remains subject to government processes.

Osmond Resources’ preliminary study has put a US$2.31 billion post-tax NPV on its Spanish rare earths and mineral sands project, but the headline economics rest on a scoping-level model and a US$300 million funding requirement. The next test is whether drilling, metallurgy, permitting and financing can turn the attractive concept into a financeable mine.

Unity Metals has extended its Camp stockwork gold discovery in Cambodia by 35 metres to the northeast, with a new hole returning 1 metre at 10.2 grams per tonne gold. The mineralisation remains open at depth and along strike, although a nearby southwest test returned no significant intersections.

Codrus Minerals has completed its acquisition of EdgeMet, adding copper and molybdenum exploration projects in Queensland and Peru alongside early-stage technology from Rice University. The transaction was funded with 230 million shares, 60 million performance rights and A$100,000 in upfront cash.

Aurum Resources has reported its best-ever grade-thickness intercept at the Boundiali Gold Project, led by 28.8 metres at 22.92 g/t gold from the BST1 deposit. The results are intended to support an early fourth-quarter resource update and a definitive feasibility study due late in 2026.

Kantra Copper has intersected 70 metres at 1.18% copper and 0.24 grams per tonne gold at the Nugent lode, extending mineralisation below its existing resource model. The results arrive ahead of a 2026 Mineral Resource Estimate scheduled for late October.

Marmota has reported multiple high-grade gold intersections from the first assays at Mainwood, the southern extension of its Greenewood discovery in South Australia. Results from only 15 of 84 sections include 4 metres at 15 grams per tonne gold, while drilling and further assays continue.
