Coeur Rochester Buttress

Q&D built this 700,000-cubic-yard, keyed-in and anchored buttress to allow for a leach pad expansion. Existing pregnant solution lines had to be extended beyond the proposed fill, which required bypassing of cyanide solution during construction to allow for ongoing mining operations.

The live lines then were encased with reinforced concrete to protect them from the weight of the buttress fill. Because this project was part of an ongoing mine operation, space was limited for staging. Coordination with mine operations happened on a daily basis.
