Halls Creek Project Scoping Study delivers compelling copper-zinc economics

Cobalt Blue has completed a Scoping Study for its Halls Creek Project in Western Australia, confirming a viable, near-term copper and zinc mining operation with strong financial returns and a modest upfront investment.

The project would develop two deposits in sequence, Onedin and Sandiego, over a 10.5-year mine life, producing copper, zinc and silver.

The Study returns a post-tax NPV of A$121 million, with an initial capital requirement of A$73 million funded from operational cashflow as the project scales.

Copper and zinc are among the most strategically important metals of the energy transition, with demand forecast to grow strongly through the next decade.

For Cobalt Blue, Halls Creek adds meaningful commodity diversification alongside the Kwinana Cobalt Refinery, providing a pathway to near-term cashflow while the company's critical minerals strategy matures.
