BHP to ramp up work at $2.5 mn Spence copper mine expansion

BHP plans to ramp up work at the ongoing $2.5 billion expansion of its Spence copper mine in Chile, as measures taken to stop the spread of COVID-19 this year set completion of the project back. The world’s biggest miner said it will speed up construction at Spence in December, with first production expected in the first half of 2021.
