Silver Age & Ship Ahoy Mine Remediation
The Gilson Gulch /Silver Age Mine Project was a “clean mine water diversion project,” designed to prevent stream contamination from mine waste. Work included the re-route of upstream headwaters drainage around the Silver Age Mine Waste Pile and removal and consolidation of mine waste away from the drainage.
The Ship Ahoy Mine is located very near the headwaters of the east tributary of Gilson Gulch and upstream of the large Silver Age Mine waste pile. The Gilson Gulch/Silver Age Mine project was aimed at preventing contamination from the Silver Age Mine waste pile to the water draining from the headwaters area and the Ship Ahoy Mine.
The engineering goals of the Project were to reduce contact of groundwater and surface water with mine waste. The project included construction of lined drainage channels, excavation and stabilization of surface water diversion channels, as well as, excavation and construction of a French drain to intercept alluvial surface waters in the upper east tributary of Gilson Gulch. The effect of this Project was to reduce contaminant loadings to water in Gilson Gulch and the Clear Creek.
