South Jordan, Utah – Rio Tinto Kennecott has successfully demonstrated the life cycle of mining with the closure and final reclamation efforts of the Barney’s Canyon Mine. Kennecott is completing the last reclamation efforts needed to restore the site to a more natural condition that is protective of public health, safety and the environment.
Reclamation is underway on the five heap leach pads, which includes soil remediation, extending liners and relaxing the slope of the heap leach pads. Additional reclamation efforts include installing additional storm water controls, removing existing buildings and revegetating the area. Reclamation efforts in Barney’s Canyon are expected to be completed in 2019 with a final investment of more than $50 million.
Rio Tinto Kennecott managing director Marc Cameron said, “We are proud of the work we are doing at Barney’s Canyon Mine because it demonstrates how we can successfully close and reclaim a mine that was once a fully operational and productive business. This should provide confidence to our stakeholders across the world that we are demonstrating responsible mining practices.”
To date, more than 800 trees and shrubs have been planted that are native to the area and will be visible throughout the Salt Lake Valley, including Rocky Mountain Maple, Gambel Oak, Saskatoon Serviceberry, Woods Rose, Mountain Mahogany and Bitterbrush.
Located on the east slope of the Oquirrh Mountains, five miles from the famous Bingham Canyon Mine, the Barney’s Canyon Mine operated from 1989 to 2013 and produced more than 2 million ounces of gold.
The Barney’s Canyon operation consisted of rotary drills, front-end loaders and 85-ton haul trucks, crushing and conveying equipment, milling, heap leaching, gold recovery and refining plants.
