U.S. President Donald Trump’s outgoing administration is set to approve the controversial land swap later this month that would give Resolution Copper (BHP and Rio Tinto) more than 2,400 acres (9.7 square kilometres) to build an Arizona copper mine (see 2014 above), even though the project would destroy religious and cultural sites sacred to the San Carlos Apache. The publication date of the environmental study on which this approval depended and which was estimated to be completed in 2021 was brought forward to December 2020. The US Forest Service agency said it had completed the study faster than expected.
