The site is located in Douglas County, Oregon, approximately 30 miles southeast of Roseburg, Oregon. The Umpqua Mine focused on the mining, milling, and processing of cinnabar ore to produce mercury. A thermal vaporization/distillation process was used to extract and condense mercury from the ore. During previous investigations in the early 2000s, a significant amount of mining and milling equipment was observed on-site in its original position in varying degrees of disrepair. This appeared to include a rotary furnace, powerhouse area, trestle, ore bins, grizzly, condenser, fuel oil tank and related equipment.
