A former pyrophyllite-U occurrence/mine located in the NW¼ sec. 36, T12S, R19E, SBM, about 10 miles NE of Glamis, W of highway 78 and E of Gables Wash, along the southern margin of the Chocolate Mountains. MRDS database accuracy for this location is not stated.
Mineralization is hosted in altered metamorphic rocks (quartzite). A contact of quartzite and sericite schist is a E-W vertical fault. A basic dike is adjacent to the contact and mostly in quartzite at surface. The U occurs in a pyrophyllite-rich zone within quartzite 50 to 100 feet E of the basic dike and 50 to 100 feet N of the quartzite-schist contact. Local rocks include schist of various types and ages, unit 2 (Southern and West-central California).
Workings include surface and underground openings comprised of a bench cut 80 feet long and 30 feet wide at 10 to 15 feet high and several smaller cuts. A vertical shaft connects with a drift adit driven W.
production information: 1000 tons of material (pyrophyllite) was mined for use as an insecticide carrier.
Analytical data results: Atomic Energy Commission samples mplace U content at 0.293%.

| ⓘ Carnotite Formula: K2(UO2)2(VO4)2 · 3H2O Description: Occurs in a metamorphosed terrain intruded by felsic dikes and plugs. The carnotite is in the altered felsic rocks associated with tornernite, in talc-bearing metamorphic rocks. References: |
| ⓘ Fluorite Formula: CaF2 |
| ⓘ Gypsum Formula: CaSO4 · 2H2O |
| ⓘ Kyanite Formula: Al2(SiO4)O |
