From introduction: During 1981 the Bureau of Mines conducted a field investigation of the Bureau of Land Management's Lime Hills, Narrows, and Sand Cove Wilderness Study Areas (WSA's), Mohave County, Arizona as part of a joint effort with the Geological Survey to make a mineral survey of the area. Surface workings and outcrops were examined and samples taken from rock sections that appeared to represent most of the mineralized area. Complete analytical results and sample descriptions are available for public inspection at the Bureau of Mines, Intermountain Field Operations Center, Building 20, Denver Federal Center, Denver, Colo. Part of the area also was examined and sampled in 1979 by L. W. Hamm, Bureau of Mines (Villalobos and Hamm, 1980), during a mineral resource study of the Paiute Primitive Area.

Abstract: Ground-water and tailings pond monitoring in the Upper Santa Cruz Basin Mines Task Force's Special Studies Area has been performed to determine the nature and extent of aquifer contamination from copper tailings pond's recharge in the basin. A monitoring program for each of three mining areas (Mines A, B, and D) was developed. Analysis of data shows that recharge from Mine A's ponds has caused increased hardness, sulfate and total dissolved solids in local ground water. However, pumpage in the area has controlled most of the water's movement. Pond recharge from Mine B has led to similar conditions, and the degraded water is moving towards a local public-supply well. Pumpage from Mine D's interceptor wells is controlling some, but not all, of the movement of recharge seepage from Mine D's ponds. Recommendations include the need for enhanced monitoring programs at each current mine site, development of a monitoring program for Mine C's area, development of water budgets for all mines, investigation of tailings pond compaction and sliming, establishment of mine closure plans for containment of recharged pond water, and the need for additional interceptor wells in several locations.
