South32 said it has exercised its option to acquire a 50% stake in the joint venture company that will own Upper Kobuk Mineral Project located in the Ambler mining district in Alaska.
The company said the move follows a successful exploration partnership with Trilogy and will help the Australian miner expand its portfolio in North America by adding high-quality copper and base metals development options.
The joint venture will retain $87.5 million of the $145 million subscription payment to fund exploration plans. The rest will be loaned back to South32, which will be repaid in installments.
