"Montana

One example where the misuse of cyanide has resulted in serious environmental damage is in that of the state of Montana. In this state, the practices of two mines in particular lead to phase out open pit and cyanide leach mining. This was set out in state law in the 1998 citizen?s initiativeI-137.

This citizen?s initiative has since halted any development of other gold projects in the state. The Seven-Up Pete Joint Venture is one such project that has been rendered not economically viable. Metallurgical testing has been carried using alternative lixiviants for extraction, but have all been proven that cyanide heap leaching is the only real option.
