EcoFlight flew with the Idaho Conservation League over the Thompson Creek molybdenum mine and the proposed Cumo Mine in Idaho.
The Boise River provides more than 20% of Idaho's drinking water. The source for this clean water may be at risk from a proposal by Mosquito Gold, a Canadian mining company, to construct the Cumo molybdenum mine in the Boise River headwaters. Mining is the number one toxic polluter in the U.S. and there is a concern that pollution from arsenic and other toxins could contaminate the Boise River headwaters if the Cumo Mine is developed.
According to Mosquito Gold, the Cumo project contains one of the largest, strategic stores of mineral wealth and may be the world's largest un-mined open pit accessible molybdenum deposit.
EcoFlight flew with the Idaho Conservation League over the Thompson Creek molybdenum mine near Clayton, Idaho, to get the aerial view of a fully developed molybdenum mine and to better anticipate the issues involved in the development of the Cumo Mine.
The Thompson Creek Molybdenum Mine is Idaho's largest mine at 3,000 acres. Located 2,000 feet above the Salmon River, contaminated water from acid mine drainage is held in the mine's gigantic tailing's dam. The mile-long, 1500-foot deep open pit and massive waste rock dumps will need monitoring and maintenance forever.
If fully developed, the Cumo Mine could be five times larger than the Thompson Creek Mine.
