The crushed rock, or tailings, remaining after the copper and silver are extracted will be a benign sand-size material de-watered to a paste-like consistency, then sent to a storage facility via a lined underground pipeline. The use of paste tailings was chosen specifically for its stability and reduced footprint. The facility will be located adjacent to Highway 200 next to the existing saw mill, approximately 5 miles from the wilderness boundary. Using best-management practices, seepage through the paste facility will be collected through a series of drains and sent to the treatment plant to meet strict water quality standards. In addition, the facility will be reclaimed concurrently during the life of the mine as illustrated in the images below.
