Latest Geological Interpretation News

Cobre has logged copper sulphide mineralisation in its first deep diamond hole at Sierra Atacama since 2021, extending the system below the existing operation. The result is encouraging but remains visual and preliminary, with laboratory assays due in October.

CZR Resources has expanded its exploration case at Croydon, with shallow gold at Frank’s Patch and Baskerville complemented by deeper mineralisation at Top Camp. The company has also lodged a mining lease application for its Buddadoo vanadium-titanium-magnetite project.

Arrow Minerals has applied for an iron ore exploration tenement adjoining Rio Tinto's Robe Valley operations in Western Australia, a move that could expand its prospective landholding by 30% to 415 square kilometres. The application remains subject to tenure award, and no resource or economic estimate has been announced.

OD6 Metals has identified high-grade fluorspar at North Horseshoe Canyon in Nevada, with selective rock-chip assays reaching 60% CaF2. The results expand an interpreted 1.5-kilometre target corridor linking the Horseshoe and Big Jim areas, but drilling is still needed to establish continuity, thickness and scale.

Minrex Resources has completed its 33-hole Barje infill program and begun a 6,604-metre greenfield campaign at Tlamino in Serbia. The drilling will test whether Barje and Liska form part of a single mineralised system extending more than 1.5 kilometres.

Atomic Eagle has identified broad interpreted uranium zones at two early-stage exploration targets in Zambia, including a 600m by 200m zone at Muntanga North Target 5. The company still needs follow-up drilling to establish whether the mineralisation is continuous and significant enough to support resource growth.

Cannindah Resources is accelerating drilling at its Cannindah Breccia deposit after identifying mineralisation beyond the existing resource and along a broader 2km structural corridor. An updated resource estimate, incorporating 45 additional drill holes and new metallurgical inputs, is targeted by the end of September.

Astral Resources has reported broad and high-grade gold intersections from two deep holes at Theia, including 22 metres at 2.73g/t and 2 metres at 12.8g/t. The results extend the evidence for mineralisation below the current resource shell, but any resource increase remains dependent on the six remaining holes and further interpretation.

Pilbara Gold has reported broad and high-grade gold intersections at its 2.1Moz Mt York project, including mineralisation about 100 metres below the current resource. The results support ongoing resource classification work, while deeper drilling and further assays could determine how much growth is ultimately added.

AuKing Mining has approved planning for an approximately 1,000-metre diamond hole at its Tundulu Rare Earths Project in Malawi. The hole will test the depth of the carbonatite system at Nathace Hill after strong initial RC results and two deep diamond intersections.

NewPeak Metals will begin a minimum 1,000-metre Phase 2 diamond drilling program at Las Opeñas in Argentina in mid-October, targeting a potentially gold-richer zone west of its recent long intercepts. The campaign is funded from the company’s completed placement, but the higher-grade western extension remains untested.

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.
