Mining began at the Plumas-Eureka Lode in 1851 across the valley. Mining at the Jamison began in the 1880’s. The Jamison was sold to its Plumas-Eureka neighbors in 1922. The underground workings are extensive with a now flooded 3 compartment main vertical shaft that ran 265ft deep.

There are several adits and shafts on the site, none of which appear on USGS Historic Topo. A dozen structures can be seen spread out wide among the trees from Google Earth.
