This district is in northern Los Angeles County about 20 miles west-northwest of Lancaster, in the foothills on the south side of Antelope Valley. Gold was discovered here in 1899, but the bulk of the production of about $200,000 was obtained in 1935-38. There has been intennittent mining and development work here since. Most of the production has been from the Rivera or Rogers-Gentry group of mines.

The ore deposits occur in a contact zone between metasediments and quartz monzonite. The ore bodies consist of zones of narrow quartz veins and stringers containing free gold and varying amounts of pyrite. The oxidized zone yielded material valued as high as $60 of gold per ton.
