Argent Minerals has intersected 18.2 metres at 187.3 g/t silver beyond the current Lode 100 resource boundary at Kempfield. Further drilling also extended Lode 200 at depth and confirmed mineralisation in under-drilled areas, although the Mineral Resource has not yet been updated.

Charger Metals has restarted diamond drilling and added an RC rig to a 10,000m campaign at its Lake Johnston lithium project in Western Australia. The programme targets extensions and infill at the 10.6Mt Medcalf resource while testing whether the conceptual Medcalf West target can be converted into a mineral resource.

Castle Minerals has identified six ranked gold targets across its 212km² Nielle project in Côte d’Ivoire, including previously unreported intercepts of up to 8m at 3.65g/t gold from surface. The company is preparing an Exploration Target for the historically drilled zone while planning new drilling, subject to the permit being granted.

Piche Resources has secured firm commitments for a $1.1 million placement at 1.8 cents a share, with attaching options offering a further potential funding pathway. The capital arrives while the company searches for a new CEO and reviews its project portfolio.

White Cliff Minerals has expanded the assay-confirmed footprint of its Rae Copper Project beyond 11.5km, while new Danvers 3 drilling has placed visible copper sulphides within 19 metres of surface. The most eye-catching Danvers 3 interval still awaits laboratory assays.

Sierra Nevada Gold has begun mobilising a five-rig, 25,000m exploration campaign at its As Safra Copper-Gold Project in Saudi Arabia. The program will test Central Copper’s resource potential while opening up more than 12km of broader discovery targets, with first assays expected in November 2026.

Greenvale Energy has identified six additional uranium targets at its Thunderball Project in the Northern Territory, tied to a newly interpreted fault structure and coincident geophysical anomalies. Early laboratory results also support uranium anomalism at Wildcard South and along a possible Hayes Creek Fault splay, although drilling has yet to begin.

Nordic Resources has recorded gold recoveries of up to 90% and copper recoveries of up to 91% at its Kopsa gold-copper project in Finland using a conventional processing route. The results will feed into an updated resource estimate expected in October, while a new 12,000-metre drilling program is already under way.

HyTerra says it has cut recurring corporate overheads by 30% before new initiatives, or 21% after including them, while reshaping its board and management. The geologic hydrogen explorer is also seeking approval for a 20:1 share consolidation and progressing a sponsored US ADR program without raising new capital.

Lightning Minerals has started a 262-sample Phase 3 soil program at its Warby Tungsten Project in North Queensland, with the first 162 samples already at the laboratory. Results expected in October will help determine whether open tungsten anomalies are ready to support maiden drilling.

Aruma Resources is adding 32 contiguous claims to its Tillex copper-silver project in Ontario, expanding the land position to approximately 28.4km². The new ground extends interpreted copper trends and introduces largely untested gold targets, while Phase 2 drilling continues to push the existing high-grade zone southwest.

Critica Limited (ASX:CRI) has delivered stronger technical results across its Jupiter rare earths and Mt Lindsay tin-tungsten projects, but the developer remains dependent on further funding. Two scoping studies targeted for Q3 2026 now carry the burden of translating resource potential and laboratory results into project economics.
