Mining in Montana has rapidly declined in recent years due to the regulatory climate in the state. Since cyanide leaching is the only economic means of recovering many of Montana's most important gold and silver deposits, repealing the cyanide ban will go a long way towards improving that climate thus helping to diversify our economy.
