AngloGold Ashanti has completed a 2,659-sample soil geochemistry program at EcoGraf’s Golden Eagle project in Tanzania, with results now pending ahead of a planned drilling phase. The work forms part of a US$9 million farm-in while EcoGraf prepares separate exploration across a broader portfolio of gold and critical-minerals targets.

Cosmo Metals has secured the Carters Road exploration licence in New South Wales after reconnaissance work returned 4.69% copper and 5.78g/t silver from a single selective rock-chip sample. The result offers an early exploration lead, but does not establish continuity, scale or economic significance.

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.

Voltaic Strategic Resources has identified malachite-rich copper mineralisation across an approximately 100-metre area at its El Dinero prospect in Western Australia. Preliminary pXRF readings reached an average 8.31% copper in one selected sample, although laboratory assays are needed before the results can be treated as representative.

Kuniko has extended the interpreted Silica Hill mineralised system by about 100 metres, with drilling encountering a broad sulphide zone and veins up to 50 centimetres thick. The key test now shifts to laboratory assays, due in four to six weeks, ahead of a planned December 2026 resource upgrade.

Culpeo Minerals has started a four-hole, 2,000-metre maiden diamond drilling programme at Vista Montana, testing a copper-molybdenum target north-east of its Lana Corina discovery. The company is also using IP surveys to refine targets, while assays from El Quillay South returned several narrow copper-gold intersections.

FMR Resources has identified a strong induced polarisation anomaly beneath historical artisanal workings at its Esperanza prospect in Chile, marking it as a priority drill target. The result is encouraging, but remains an early-stage geophysical signal pending 3D modelling, fieldwork and drilling.

Botala Energy has secured three wholly owned Botswana prospecting licences covering 1,812km², taking its Serowe CBM footprint beyond 6,000km². The expansion comes as the company prepares to flow-test Serowe-3.5B, while the new acreage remains an interpreted exploration opportunity rather than a booked resource.

Talonx Resources has identified copper and broader base-metal exploration potential across its 1,000km² Kihabe Project in Botswana, supported by historical copper intersections and established zinc-lead-silver resources. The immediate task is to turn an exploration thesis into drill-ready targets, with no new drilling or copper resource reported in the announcement.

Australasian Metals has locked in a three-month exclusive option to acquire majority stakes in two promising lithium projects in Côte d'Ivoire, marking a strategic move into West Africa's emerging critical minerals scene.

Right Resources has boosted its Blue Prospect gold target with a standout 5.16 g/t rock-chip assay, refining a 4 km gold corridor and setting the stage for maiden drilling in September.

Turnstone Resources has secured A$1.1 million through a two-tranche placement priced at a premium to the last trade, aiming to fast-track exploration in Sweden and review German potash assets.
