Mineral resource potential of the Chuckwalla Mountains Wilderness Study Area (CDCA-348), Riverside County, California. Summary report
This report presents the results of a mineral survey of the Chuckwalla Mountains Wilderness Study Area (CDCA-348) California Desert Conservation Area, Riverside County, California. Geologic and geochemical investigations and a survey of mines and prospects indicate that those parts of the Study Area (chiefly in the Red Clound Canyon and Corn Springs Wash vicinities) that are intruded by propylitically altered mafic dikes with spatially associated quartz veins and shear zones have moderate or high potential for the presence of undiscovered low- to medium-grade gold, silver, and tungsten resources in vein deposits. High stream-sediment concentrations of molybdenum strongly suggest that parts of those areas intruded by the dikes also contain molybdenum-bearing minerals and thus have moderate or high potential for the presence of undiscovered molybdenum resources. However, there has been no recorded production of molybdenum in the region and any resources that may be present in the study area are likely to be significant only if the mineralized quartz veins and shear zones are manifestations of an extensive subsurface quartz-vein stockwork system. All areas with moderate or high potential for gold, silver, or molybdenum resources also have low potential for the presence of undiscovered copper and lead resources. Low potential for the presence of undiscovered tin and thorium resources exists in the north part of the wilderness study area. Sand, gravel, and stone suitable for construction materials are found in the study area, but similar or better quality materials are abundant and accessible outside the area. No new mineral occurrence was located during this study. 21 refs.
