The Jessie, which operated from 1885 into the 1930s, was one of the larger mines in the Breckenridge area. The mine primarily produced gold but also significant amounts of silver and lead.
Today, the Jessie stamp mill is all that remains of the original mine. Built in 1893-1894, the stamp mill crushed large chunks of ore to sand-sized particles in order to extract valuable gold, silver and lead.
The Jessie is the best example of a stamp mill in Summit County, but was at risk of collapse and had a severe lean. After assessing the structural integrity of the mill in 2012, the Alliance undertook a stabilization effort in 2013 using winches, cabling and wooden bracing to bring the mill back to near plumb. Additional plans for the mill include capping the stamp mill bases, treating the wood and improving drainage around the site.
The Jessie Mill is located on Gold Run Road, approximately 1/3 mile from the Gold Run Road Trailhead, on jointly owned Town of Breckenridge and Summit County open space. Stabilization work to date has been funded by the Tow n of Breckenridge.
