This report presents the results of a mineral survey of part of the Jacumba (In-ko-pah) Wilderness Study Area (CDCA-368) that was designated by the Bureau of Land Management as suitable for mineral surveys. In this report, the area studied is referred to as the “wilderness study area”, or simply “the study area.” The study area encompasses approximately 28,443 acres in southwestern Imperial County, Calif. Field work for this report was carried out between 1983 and 1985. Numerous mines, prospects, and claims are present in the study area, but none are being actively mined or prospected. Three sites inside the study area have identified limestone resources that total about 1.8 million tons. Four areas in the northwestern, northern, and eastern parts of the study area have high potential for undiscovered limestone resources. Two north-trending belts in the western and eastern parts of the study area have low resource potential for tungsten.
