Sunday Complex

The Sunday Mine Complex consists of the Sunday/St. Jude, West Sunday, Topaz, and Carnation Mines in western San Miguel County, Colorado. These are mature mines with extensive existing underground workings. The most recent activity occurred at the Topaz Mine with an initial development drift completed in 2007, followed by mining until 2009, at which time the project was placed on standby.

The Sunday Mine Complex is currently on care and maintenance, with permit-related activities necessary for restarting the mines underway.
