Latest Resource Upgrades News

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.

Alma Metals has intersected 383.8 metres at 0.25% copper from just 10.2 metres at its Briggs project, including a higher-grade 76.7-metre zone at 0.34%. The result supports the company’s effort to upgrade parts of the resource ahead of a pre-feasibility study, although the intersection remains a downhole measurement and ended in mineralisation.

Canterbury Resources has reported a broad copper-molybdenum intercept at Briggs while early core observations suggest its John Hill deposit may extend beyond the current resource boundary. The results support ongoing resource upgrades and feasibility work, but John Hill assays are still pending.

Killi Resources has intersected a 50-metre zone of visually estimated crystalline magnetite 600 metres south of Lodestone’s existing 110Mt inferred resource. The result also identified a separate 16-metre hanging-wall zone, but assays and metallurgical testing are still pending.

Sunstone Metals has expanded its Bramaderos gold-equivalent resource to 3.6Moz and reported new Porotillo and Copete discoveries, but its FY2026 accounts carry a material uncertainty over going concern. A post-year-end A$9.94 million placement has improved liquidity, although further equity funding remains central to the exploration plan.

Nexus Minerals has more than doubled the Wallbrook Gold Project’s Mineral Resource to 631,000oz, adding maiden resources at Payns and Branches. Combined with Pinnacles, group resources now stand at 709,000oz, although most Wallbrook ounces remain Inferred and no Ore Reserve has been defined.

Prospect Resources has expanded drilling at Nyungu Central after returning a 27-metre copper intercept outside the existing resource, while maiden drilling at Sharamba confirms a new copper discovery. The results add momentum to Mumbezhi’s growth story, but most Phase 3 assays remain outstanding and no resource update has yet been made.

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.

Turaco Gold has confirmed depth and strike extensions at the Begnopan deposit in Côte d’Ivoire, including several high-grade gold intersections from the first 69 holes of a 113-hole program. The results could support a resource classification upgrade and eventual inclusion of Begnopan in Afema’s ore reserve, but no revised resource or reserve has yet been published.

Resources & Energy Group has reported strong gold intercepts from grade control drilling at its Maranoa project in Western Australia, including 2 metres at 15.84g/t and 4 metres at 10.38g/t. The results support further mine-planning work, but do not yet change the deposit’s existing inferred resource.

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.

Broken Hill Gold has started a 48 line-kilometre induced polarisation survey and 670 line-kilometre magnetic program at White Dam, targeting sulphide mineralisation beneath existing oxide prospects. A second diamond rig is also mobilising, but the next value test remains firmly in the ground: geophysical anomalies must translate into drilling results and an upgraded resource.
