US-based Perpetua Resources Corporation is trying to revive an abandoned mine in the state of Idaho that it says could eliminate the US military’s reliance on foreign – and potentially unreliable – sources for antimony, a critical mineral used to make ammunition and missiles.
China and Russia produce most of the world’s antimony, which has commercial and military applications.
