Placerville is a census-designated place (CDP) and post office in and governed by San Miguel County, Colorado, United States.

By the fall of 1899, development was described as "of the most superficial character," although Frenzel had driven one tunnel 18 feet into the rock.

[7] At least five mines were active at one time, and by 1919 the two ore mills at Placerville were producing 30% of the world's vanadium.

In 1909, the failure of the Trout Lake Dam caused the flooding of Placerville as well as Sawpit and Newmire.

[11] Beginning about 1950, the small uranium content of the ore was also recovered from the ore.[12] The Placerville CDP has an area of 485 acres (1.961 km2), all land.
