Unicorn Mineral Resources Plc is preparing to acquire a 75% controlling stake in the Klein Aub Copper Mine in Namibia by April 2026. Preliminary metallurgical testing indicates copper recovery rates of 60% to 70% from slimes and 35% to 45% from tailings.

The mine, operational from 1966 to 1987, produced approximately 55,000 tonnes of copper. Unicorn is collaborating with Draslovka to assess glycine-based leaching for extraction. The potential resource includes 5.59 million tonnes of tailings and slimes, estimated to host 15,460 tonnes of copper and 1.4 million ounces of silver. The company is also negotiating for additional copper assets in Namibia.
