Southwest Oregon Rivers

Rough and Ready Creek and Baldface Creek are nationally outstanding and “eligible” to be added to the National Wild and Scenic River System. The US Department of Agriculture recommended Congress designate 34,000 acres of their watersheds as Wilderness in 2004. They remain unprotected today. 

Mercury air pollution from gold mines has dropped by half!

December 10, 2013 • Bonnie Gestring

It's great to have some good news to share, and this one's a whopper.  Mercury air pollution from U.S. gold mines has dropped by half - from over 5,000 pounds in 2006 to 2,500 pounds in 2012.  This is a remarkable change!

The biggest polluters were giant, open-pit gold mines in northern Nevada, where the amount of mercury pollution was off the charts!  Yet, there were no regulations that required these mines to control their emissions.

Mercury Emissions from Gold Mining

December 10, 2013 • Bonnie Gestring

While much attention has been placed on coal-fired power plants and their mercury emissions, scant notice has been paid to gold mines and their role as the fifth largest source of mercury air emissions in the U.S. Most of the mercury air emissions from gold mines are released by mines that use ore roasters to process the gold.

Baja California Sur

Mining exploration is on the upswing in Baja California Sur, whose residents mostly farm or engage in the tourism industry. One proposed project in particular, the Los Cardones mine, currently owned by Invecture Group, a Mexican company, closely affiliated with Vancouver-based Frontera Mining Corporation, draws a great deal concern from the local communities. Covering more than 13,000 hectares of land, the anticipated risks of the proposed Los Cardones mine include contaminated ground and drinking water, cyanide pollution and high levels of dust laced with arsenic and heavy metals.


On October 16, 2001, a tailings dam burst at the Tarkwa gold mine in the Wassa West District of Ghana sending thousands of cubic meters of mine waste into the Asuman River and contaminating it with cyanide and heavy metals. The Tarkwa mine is operated by Gold Fields Ghana, a South African gold mining company. The disaster left more than one thousand people without access to drinking water. Virtually all life forms in the river and its tributary were killed. Hundreds of dead fish, crabs, and birds lay on the banks of the river and floated to the surface.
