First Quantum is said to offer $700m for Zambia mine

First Quantum Minerals has offered to buy the Zambian government’s 20% stake in Africa’s biggest copper mine for as much as $700-million, according to two people familiar with the transaction.

Vancouver-based First Quantum already owns 80% of the Kansanshi mine in Zambia’s North-Western Province, while State-owned ZCCM Investments Holdings holds the rest.
