CHEYENNE, Wyo. (AP) — President Donald Trump is taking a step toward granting the U.S. mining industry’s biggest wishes by singling out one metal as a focus of his domestic minerals policy: copper.

An executive order mandates a review of the threats posed by over-reliance on foreign copper, and recommendations for increasing domestic supply.

The US President's copper imports investigation has contributed to rapidly escalating global trade tensions. The metal is a vital component in a number of products, and is also important for the green transition.
