Latest Mineral Resource Estimation News

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.

Auris Minerals has identified potential strike extensions to gold mineralisation at Jacques East and returned further anomalous results at Frenchys South from 22 air core holes. The more decisive test now shifts to more than 100 one-metre samples intended to reveal whether the composite grades conceal higher-grade, nuggety zones.

Victory Metals has secured a 2,006-hectare mining lease for its North Stanmore heavy rare earths project in Western Australia. The grant removes a key tenure hurdle, but technical studies, approvals, offtake agreements and financing still stand between the project and a development decision.

Sinclair Gold has doubled the JORC Mineral Resource at its Mt Henry project to 1.8 million ounces after just 20,426 metres of drilling. The shallow resource remains open, with five rigs operating and assays pending from 25 holes outside the current estimate.

AuKing Mining has reported wide, high-grade rare earth intersections from maiden RC drilling at its Tundulu project in Malawi, including 91 metres at 1.51% TREO. The results also reveal unusually strong heavy rare earth enrichment and have prompted the company to fast-track a maiden resource estimate targeted before the end of 2026.

Boab Metals has reported high-grade silver-lead intercepts outside the current Sorby Hills FEED Study pit designs, led by 12.62 metres at 204g/t silver equivalent. The results have pushed the company to extend its growth drilling program as it assesses potential resource, reserve and mine-life additions.

Encounter Resources has identified a shallow, high-grade niobium zone at Joyce, 6 kilometres east of its Green deposit, with drilling ending in mineralisation. Assays from surrounding holes are due in October and will determine whether the zone has meaningful lateral continuity.

Resolution Minerals has finished its largest-ever exploration program at the Horse Heaven project in Idaho, drilling 42 diamond holes across 12,236 metres. The work sets up a substantial run of gold, tungsten and multi-element assay results, but the completed program has not yet produced new assay data in this announcement.

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.

BPM Minerals has secured the final approvals for a maiden approximately 10,000-metre RC drilling campaign at its untested Bonnie and Clyde prospect in Western Australia. Drilling is expected to begin within 5-10 days, putting a more than 6-kilometre gold-in-soil anomaly to its first meaningful test.

Kingsgate Consolidated has increased Nueva Esperanza’s Ore Reserves by 31% for silver and 37% for gold, extending the assumed reserve life beyond 12 years. The gains are largely driven by higher price assumptions and lower royalties rather than new drilling.

Odyssey Gold has identified a previously unmodelled high-grade gold structure west of its Cable deposit, with drilling also strengthening the emerging Argos lode. The results could expand the Tuckanarra resource envelope, although continuity and scale remain to be established.
