Mineralization is a quartz vein deposit hosted in greenstone and slate. The vein was called the Alpine, and may be a spur of the Empire vein of the Plymouth Mine. It descends to 500 feet of depth and branches as the results of a 400 foot wide greenstone block in the slate. Local rocks include Jurassic marine rocks, unit 1 (Western Sierra Nevada and Western Klamath Mountains).
