Open-pit, heap-leach, cyanide gold mining is so dangerous, it’s banned just a few miles across the Idaho border in Montana.   

Cyanide is a chemical asphyxiant that can kill people and wildlife when ingested, breathed, or absorbed through the skin. The use of cyanide in open-pit, heap-leach gold mining poses a dangerous threat, not only because it never goes away, but because it can be difficult to capture and treat once it has been released.  

Excellon has repeatedly drawn comparisons between potential mining operations at Kilgore Project and existing mining operations at Round Mountain Mine in Nevada, suggesting that the Kilgore Project could have the potential to be a large mine with a long operational life. 

An open-pit, heap-leach, cyanide gold mine in the Centennials threatens the cold, clear creeks that begin in the foothills. 

These creeks recharge the Eastern Snake Plain Aquifer, which is the only source of clean drinking water for 300,000 people in Rexburg, Idaho Falls, Twin Falls, and the surrounding communities. The Centennial Mountains are also home to family traditions like hunting, hiking, motorized recreation, and fishing.
