Latest Resource Estimation News

Medallion Metals has shifted from project preparation to execution, with Ravensthorpe fully permitted, Forrestania acquired and Cosmic Boy refurbishment underway. The transition is funded by cash, equity and a US$50 million Trafigura facility, but production delivery and rehabilitation liabilities remain substantial tests.

Marmota has expanded drilling across its Greenewood and Mainwood gold targets after intersecting geology resembling earlier favourable zones. With 313 holes now completed, the first assays are expected next week, although the announcement contains no new grades or quantified mineralisation.

Talonx Resources Limited (ASX:TXR) is positioning its portfolio around two distinct exploration propositions: a near-term maiden resource pathway at Viking’s Beaker 2 prospect and district-scale copper potential at Kihabe in Botswana. The September investor presentation largely repackages previously reported results, rather than announcing a new discovery or resource upgrade.

Basin Energy has begun preliminary leachability and XRD studies at its Newmans rare earth discovery, with follow-up drilling assays due imminently. The early-stage program adds a recoverability test to a project already showing a 3.3 km mineralised corridor in northwest Queensland.

Yandal Resources posted its busiest exploration year yet, expanding the Arrakis discovery and ending FY2026 with 450,200 ounces of reported resources and $9.7 million in cash. But a larger loss, material going-concern uncertainty and a CEO transition leave the company needing to convert drilling momentum into resources and renewed funding support.

Black Canyon has spent the 2026 financial year moving Wandanya from discovery towards resource definition, backed by 17,200 metres of drilling and encouraging manganese beneficiation results. The exploration company ended the year with $7.77 million in cash and no debt, but remains reliant on future funding before any development decision can be made.

PC Gold’s Spring Hill project emerged from FY2026 with a sharply larger resource, fresh institutional funding and a clearer path towards feasibility studies. The gold explorer remains pre-production and loss-making, but its post-year-end A$75 million raise gives it substantial room to expand drilling and development work.

Southern Hemisphere Mining has reported its strongest Llahuin drilling results yet, but the copper explorer ended FY26 with just $110,027 in cash and a material going-concern uncertainty. The company is relying on further funding, related-party borrowings, asset sales and a possible Chilean VAT refund to keep exploration moving.

West Coast Silver has secured a prospecting licence immediately west of its Elizabeth Hill mining lease, opening a new near-mine exploration target with historical silver, copper, nickel and palladium anomalism. The company plans to validate the old data before deciding whether to drill.

Power Minerals has outlined a maiden conceptual Exploration Target of 9.2 million to 10.7 million tonnes at Morro do Ferro in Brazil, grading 7.8% to 9.2% TREO. The result gives the ongoing drilling program a clearer target, but 43% of the upper estimate comes from an untested projected extension and nine recent holes remain unassayed.

Kincora Copper says 2026 drilling has identified multiple porphyry-style intrusive complexes across its Nevertire and Nevertire South licences, expanding the interpreted prospective strike beyond 40 kilometres. The results remain early-stage, but AngloGold Ashanti’s potential A$100 million earn-in gives the exploration program meaningful financial backing.

GBM Resources has returned a broad 101-metre gold intersection at 2.63g/t from Lone Sister, with higher-grade intervals pointing to potential local grade uplift at Twin Hills. A further 8,400 metres of assays remain pending before the planned December-quarter resource update.
