Rio Tinto under 'immense pressure' to develop US copper project
Rio Tinto is under "immense pressure" from the US government to develop its Resolution copper project in the United States, given the copper it holds accounts for a quarter of all US reserves, its chair Dominic Barton said on Thursday.
Copper is vital for the transition to green energy but the project in Arizona is opposed by all of the state's tribal councils, including the San Carlos Apache because it would destroy a heritage site of religious significance.
