Latest Resource Modelling News

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.

Estrella Resources has expanded its Timor-Leste exploration footprint by 100km2 while securing conditional approval to export a 100-tonne manganese sample to an Indonesian customer. The company is also preparing 3,000 metres of drilling and a possible upgrade to part of its 621Mt Werumata limestone resource.

Barton Gold has reported broad, shallow high-grade gold intersections from its 39,000-metre Phase 2 drilling program at Tunkillia, including 11 metres at 8.73g/t gold. Final assays are still pending before updated gold and silver resources, with the pre-feasibility study targeted for Q1 CY27.

Resolution Minerals has reported its strongest gold grades to date at Golden Gate South, including 1 metre at 14.8 g/t gold, while extending the identified mineralised zone to approximately 600 metres. The results point to possible higher-grade feeder zones, but true widths and the broader continuity of the system remain unconfirmed.

Breakthrough Minerals has extended copper-gold mineralisation beyond the existing Turpentine resource model, with the northernmost hole returning 5 metres at 3.75% CuEq. A dedicated RC rig is due to resume drilling next week as the company tests how far the system continues.

Aureka Resources has reported high-grade gold mineralisation beyond the current inferred resource at its Irvine project in Victoria, including a 4.74g/t intercept at depth and the first significant results from a 2km gap between established lodes. The results expand the exploration story, but remain early-stage drilling data with further assays pending.

Lunnon Metals has reported strong gold intersections from 36 holes at its Foster-Baker project, including a standout 1 metre at 80.80 g/t gold at Hustler and broader mineralisation at Koombana. The results will feed updated resource models before a scoping study considers whether the two deposits could support future mining alongside a Lady Herial cut-back.

McLaren Minerals has reported broad, near-surface heavy mineralisation from 61 holes at its Western Australian titanium project, led by 24 metres at 7.54% HM. The results strengthen the dataset for a resource update, but do not yet establish an Ore Reserve or project economics.

Western Gold Resources is pursuing multiple processing alternatives for Gold Duke after Wiluna Mining deferred third-party tolling, while revising the project’s study around a larger resource. The company is also considering corporate opportunities, but no processing agreement, transaction or expanded mine plan has been secured.

GreenTech Metals has returned its strongest multi-metre copper result to date at the Ayshia deposit, with gold, silver and zinc credits included. The intersection sits approximately 65 metres beyond the existing resource envelope, although its true width remains unconfirmed.

Aspire Mining has retained the Ovoot project’s 130.1 million-tonne JORC Coal Reserve while redesigning how the Mongolian mine is funded and built. The refreshed model forecasts a US$1.48 billion post-tax NPV10, but depends on debt raising, infrastructure delivery and a 12% Inferred Resource contribution to planned output.

Kuniko-funded drilling has extended the interpreted Silica Hill sulphide system beyond Impact Minerals’ existing resource model, with assays due within four to six weeks. The results could feed a December resource update, but the latest intersections remain visual observations rather than confirmed gold or silver grades.
