PHOENIX -- A Canadian mining company said it has agreed to buy an Arizona copper mine and its related railroad for $650 million.
Vancouver-based Capstone Mining Corp. is expected to complete the buy of BHP Billiton's Pinto Valley Mine in the second half of this year, as it looks to expand into a midsize copper producer.
Capstone CEO Darren Pylot said in a press released that the mine will give the company its third producing mine.
Unloading the mine means BHP has sold off $5 billion in assets over the past year.
The deal is subject to regulatory approval.
