Latest Economic Assessment News

Orezone Gold has outlined a 14-year plan for its newly acquired Casa Berardi mine, targeting 1.63 million ounces of production and an after-tax NPV of US$1.05 billion. The economics are substantial, but the plan remains a preliminary assessment built partly on Inferred Resources and requires significant capital and permitting work.

Kaili Resources has reported a peak one-metre assay of 1,125.51 ppm total rare earth oxides from shallow aircore drilling at its Coodalya tenement in South Australia. The result adds to an emerging zone of elevated values, but the early-stage program has not yet established continuity, scale or economic significance.

Tivan has won approval to add 50 square kilometres to its Baucau copper-gold project in Timor-Leste, securing ground over a large magnetic anomaly. The expansion comes as the company acknowledges an executive chairman’s personal X post previewed an assay announcement before ASX release and was not authorised under its disclosure policy.

Sarytogan Graphite has intersected 318 metres of copper mineralisation from surface at its Ilksan prospect in central Kazakhstan, including a higher-grade 15.2-metre zone grading 0.40% copper. The result extends the system identified in an earlier hole, with assays from a deeper 452-metre hole due in the coming weeks.

Charger Metals has mobilised an RC rig for a 10,000m programme aimed at expanding and upgrading confidence in its 10.6Mt Medcalf lithium resource. The work is funded by the $3.752 million cash sale of the Bynoe Lithium Project and comes as Charger commits to a scoping study at Lake Johnston.

Enova Mining reduced its half-year loss to $790,000, but an explicit going-concern warning puts future funding at the centre of its rare earth exploration story. The company ended June with $723,000 in cash while advancing several high-grade exploration targets across Brazil and Australia.

North Stawell Minerals has used a conference presentation to position Darlington and Darlington West as its leading tests of the Stawell gold model, while outlining a broader Victorian exploration pipeline. The company stresses that the drilling results and resource figures presented have been previously reported, making follow-up work rather than a fresh discovery the key investor question.

Gold Mountain has identified clustered niobium, magnet rare earth and phosphate anomalies across four Araxá prospects after expanding its stream sediment dataset to 515 samples. The results sharpen exploration targets, but the project remains well short of drilling, resource definition or economic assessment.

Golden Dragon Mining has extended the Cue Gold Project’s high-grade story, with Behring Bore returning 4 metres at 6.98 g/t gold and Coodardy mineralisation now defined across about 500 metres of strike. A larger 2,500-metre RC program will test whether the zones continue at depth and along strike.

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.

DPM Metals has extended mineralization beyond the existing Dumitru Potok resource in Serbia, led by a 21-metre interval grading 5.44% copper equivalent. The company will add up to 15,000 metres to its 2026 drilling campaign as it works towards a resource update and preliminary economic assessment.

Kingston Resources says infill drilling at Jack’s Hut has confirmed the location and continuity of polymetallic mineralisation targeted for potential underground mining at Mineral Hill. The results will feed into a resource update, while surface drilling in October will test extensions beyond the current resource.
