IGO is conducting due diligence and talks between the companies have not been completed, it said in response to a media report that it had beaten out special purpose acquisition company Metals Acquisition Corp for the mine.

"IGO has made no decision and nor has it entered into anydefinitive acquisition agreement with respect to CSA," it said in a statement.

The CSA mine is one of Australia's highest-grade copper mines and produces about 50,000 tonnes every year, according to Glencore's website.

IGO has been dealmaking in recent months, offering A$1.10 billion ($789 million) for nickel producer Western Areas in December, and buying Tianqi Lithium's Australian assets for A$1.4 billion in June.
