Hardrock mining

Written by Jared Diamond

U.S. taxpayers currently face a liability of up to $12 billion to clean up and restore hardrock mines.  Why is our liablility so large, when governments have supposedly been requiring financial assurance of cleanup costs?  Part of the difficult is that assurance costs are underestimated by the mining companies, and the two states with the biggest taxpayer liablilities (Arizona and Nevada) accept mining company self-guarantees and not requiring insurance bonds.
