Cobalt Blue has unveiled a suite of value-adding opportunities at its Halls Creek project in Western Australia, following a review of engineering pathways and historical exploration data.
The company is focused on significantly enhancing project economics through initiatives aimed at expanding margins, unlocking new revenue streams, and accelerating exploration across its tenement package.
The identified upside “offers immense value-add to the core project outlined in the recent scoping study”.
“Cobalt Blue has the right team to unlock silver and cobalt credits, potential driving major uplifts in cashflow and return on installed plant. Resource growth, and associated project life could be realised through the drill-ready exploration opportunities,” Cobalt Blue CEO Dr Andrew Tong said.
A key focus of the review is recovering silver from the Onedin deposit during stage one operations. Although currently excluded from financial modelling, the production target hosts material with an average grade of 37 g/t silver, equating to 3.6 million ounces. With silver trading at around $58/oz, its inclusion could significantly lift project margins.
Stage two, which targets underground mining at the Sandiego deposit, may also benefit from cobalt credits. Historical drilling shows cobalt occurs alongside high-grade copper-zinc zones. If incorporated into future resource estimates, cobalt could provide a valuable by-product credit and support the company’s Kwinana battery metals strategy.
Cobalt Blue is also investigating a centralised processing hub to integrate nearby satellite deposits such as Mount Angelo North and Bommie Porphyry Copper. This strategy could boost production scale, lower unit capital intensity, and extend the project’s life beyond the current 10-year model.
Exploration is ramping up across the broader Halls Creek tenement. Sandiego North has emerged as a priority target, with recent drilling confirming high-grade copper mineralisation north of the existing resource. A 700-metre copper-in-soil anomaly and significant intersections – such as five metres at 1.4 per cent Cu – position the area for near-term resource growth.
