Latest Resource Estimation News

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.

Core Lithium has moved Finniss from care and maintenance back into active mining, with first spodumene concentrate produced after year end and a December-quarter shipment targeted. The restart leaves the company with A$181.8 million in cash, but also a substantial execution task ahead as Grants ramps up and BP33 is developed.

Odyssey Gold’s latest drilling has added high-grade hits outside current resource boundaries and strengthened the case for a connected Cable-Bollard-Highway mineralised system at Tuckanarra. Preliminary fresh-rock testwork also returned recoveries of up to 99%, although the results remain exploration-stage and an updated resource is still to come.

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.

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.

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.

Lefroy Exploration has moved from explorer to gold producer after Lucky Strike delivered its first gold, while Mt Martin and Burns advanced towards potential development. The milestone comes alongside a $2.136 million loss and an auditor warning that uncertain profit distributions may require further funding.

Altoro Metals says underground drilling has expanded the apparent width of the Emilia zinc mineralised system beyond 100 metres, although assays from nine holes are still pending. The company is combining four historical workings into one Novales Project as it prepares further drilling, a resource upgrade and mine restart documents.

Lodestar Minerals has received all assays from a 12,417-metre, 106-hole RC drilling program at Ned’s Creek, supporting its existing exploration target across three gold prospects. A maiden Mineral Resource Estimate is now expected in the second half of October, although reported widths remain subject to geological interpretation and true-width confirmation.

Cannindah Resources has identified a higher-tenor copper, gold and silver zone at its Appletree Prospect, with grades increasing southward toward a potential buried porphyry centre. Three diamond-hole assays remain outstanding before the company commits to the next phase of drilling.

Forrestania Resources has increased the British Hill JORC Mineral Resource Estimate by 21% to 212,400 ounces of gold, with higher-confidence Indicated ounces rising 37%. Drilling is continuing, but the project remains at the resource and study stage rather than production.
