A Gypsum occurrence divided between two deposits located in secs. 13 & 14, T18S, R15E. The deposit in section 14 is 1/2 mile NE of the Old World Copper Mine, and the one in sec. 13 is in a gulch NE of the Heavy Weight Mine, on military reservation land.
Mineralization is a gypsum deposit hosted in the Epitaph Dolomite. There are two areas with faulted gypsum beds - 50 to 60 feet thick and 600 to 1800 feet long.
The gypsum is of a good grade but of limited extent. Difficult access and steep dip limit the exploitation possibilities.
