Cobalt Blue Holdings shares more than doubled in early October 2025 after the company secured full ownership of the Broken Hill Cobalt Project and paid off a final A$1 million debt to American Rare Earths. The company is advancing plans for a cobalt sulfate refinery in Kwinana, with a supply deal signed with Glencore. Cobalt prices rebounded to $35,000 per tonne, up 44% year-on-year.
