This district is on the Klamath River in the extreme northeast corner of Humboldt County in the vicinity of the town of Orleans. It is mainly a placer-mining district. There was mining here during and after the gold rush that continued through the early 1900s. The Pearch hydraulic mine was active during the 1930s.
The gold-bearing deposits are stream gravels in the Klamath River and extensive older bench gravels about 50 to 80 feet above the level of the present river. Bedrock is slate and schist. The bench gravels were mined by hydraulicking. The gold is fine to medium, and some platinum is present.
