Canada’s First Quantum Minerals has put a private placement at fellow junior miner Zincore Metals, and now holds 19.9% of the latter. Some of the shares were bought from Zincore’s largest shareholder, Inversiones Pacasmayo. Furthermore, First Quantum and the junior miner signed a memorandum of understanding that allows the former to earn up to 80% of Zincore's Dolores copper-molybdenum porphyry in Peru, committing to invest on exploration of the early-stage venture.
