Cyanide leach mining is a technique that extracts gold and silver embedded in large amounts of rock by trickling cyanide through rock piles. Cyanide dissolves the gold and silver into a solution. The precious metals are then extracted. In 1998 voters passed Initiative 137 by a 52 to 48 percent margin, banning that practice. The ban came before
