A former surface gypsum mine in secs. 9 & 16, T1S, R18E, 3 miles west of San Carlos.

Mineralization is a lacustrine gypsum deposit in late Tertiary or Pleistocene (or both) lake beds. There are 3 to 5 gypsum beds totalling 2 to 10 feet (3.05 meters) thick in 100-150 foot thick exposures of gypsum, mudstone, siltstone, and sandstone, generally striking NW and dipping 15 to 25SW; however, at the NW end on the outcrop the beds are nearly flat, or have a slight northward dip. The gypsum is generally white and granular and in the outcrops has a few seams and pockets of clay scattered through it. The deposit is covered by overburden of variable thickness. Gypsum beds may extend through a 9 acre area.

Assay data: Grade is "fair to good."

Reserves: As a rough estimate, perhaps 100,000 tons of gypsum might be recovered from the thickest beds by open-pit methods.

Workings: The Rev. F.J. Uplegger utilized a small amount many years ago to make a plaster for inscriptions. Mined on a small scale for local use.
