Sept 23 (Reuters) - Canada’s First Quantum Minerals Ltd on Monday confirmed it was in talks with China-based Jiangxi Copper Co Ltd for a potential sale of a minority interest in its Zambian copper assets.
The company, however, said it had no knowledge of any potential takeover bids, sending its shares down 10% in morning trading.
First Quantum’s shares had gained about 20% since Thursday after Bloomberg reported, citing sources, that the Canadian miner had attracted preliminary buyout interest and was working with advisers to weigh options.
The company has been embroiled in a dispute with the Zambian government after being handed a $5.8 billion bill for unpaid import duties last year.
The Zambian government’s decision to appoint a provisional liquidator to run Vedanta Resources’ Konkola Copper Mines, claiming licence breach, has added to concerns for international miners such as First Quantum.
A Jiangxi Copper source said the company had recently bought a stake of almost 10% in First Quantum on the secondary market, below the threshold for disclosure for Toronto-listed companies. Jiangxi did not respond to a request for comment.
A minority stake in First Quantum’s Zambian assets - Kansanshi and Sentinel - could fetch about $2 billion, according to Scotiabank analysts.
The company produced 605,853 tonnes of copper in 2018, with the Kansanshi and Sentinel mines accounting for more than 78% of the total production.
Shares of First Quantum, which had a market valuation of C$8.42 billion as of Friday close, were trading at C$10.94 on the Toronto Stock Exchange.
