Coppermoly to Acquire 100% Interest in Wyemandoo Project

Coppermoly Limited (ASX:COY) (“ Coppermoly ” or the “ Company ”) is pleased to announce it has entered into a binding sale agreement with Aldoro Resources Limited (ASX:ARN) to acquire 100% of the Wyemandoo Project in Western Australia.

Under the agreement, Coppermoly will acquire Aldoro’s directly held interest in the Project as well as 100% of the issued capital in Altilium Metals Pty Ltd, the holder of the remaining interest in Wyemandoo, for a cash consideration of $100,000.

Completion of the transaction remains subject to customary conditions precedent, including due diligence, regulatory approvals and assignment documentation.

Situated in a highly prospective region of Western Australia, the Wyemandoo Project is considered prospective for critical minerals including rubidium, lithium and tungsten. Rubidium is a niche but valuable element with applications in advanced electronics, specialty glass and medical imaging. Lithium remains a cornerstone of the clean energy transition, being essential for rechargeable batteries that power electric vehicles and renewable energy storage, while tungsten is a strategic industrial metal, known for its strength and durability in hard metals, drilling equipment and defence technologies.

Coppermoly’s Managing Director and CEO Dickson Leah commented:

“We are delighted to be adding the Wyemandoo Project to our portfolio. This acquisition gives Coppermoly exposure to ground that is considered prospective for critical minerals at a time when demand is only increasing. Our team is excited to begin detailed exploration work and unlock the Project’s potential for our shareholders”
