This district is in south-central Siskiyou County west of the town of Gazelle. The Dewey mine, which was worked from the 1880s until about 1907, has been the chief source of gold, its total output valued at about $900,000. The region is underlain by metasedimentary rocks, which are of Silurian age, and small stocks of granodiorite. The gold-quartz veins occur in granodiorite and contain abundant sulfides.
