Cyanide leach mining: What is it? Why so dangerous? And why you pay the bill.

BISHOP, California -- To spread awareness of the threat that taxpayer-subsidized, cyanide-based gold mining poses to public lands and waters in the American West, the Owens Valley-based Friends of the Inyo provides an instructive presentation on YouTube that explains cyanide leach mining.

The presenter of "The Dirty Truth About Modern Cyanide Gold Mining," Bonnie Gestring, is Northwest program director at Earthworks, a Montana conservation organization. The devastating consequences and costs born by Montana taxpayers compelled voters there to ban new cyanide leach mines in 1998.

We're sharing Gestring's talk because eastern California's rural Owens Valley and Inyo Range face the same threat as Idaho's Centennial Mountains, in rural Clark County.

As Gestring explains, industrial-scale cyanide-leach gold mining operations, like those now devastating and closing off landscapes in Nevada, are an existential threat to the American public's access to and use of Western public lands.
