A former Mn-Cu occurrence/mine located in sec. 1, T2N, R25E, SBM, 4.5 km (2.8 miles) WNW of Monument Peak (coordinates of record), on Bureau of Land Management administered wilderness land (Whipple Mountains Wilderness Study Area). MRDS database stated accuracy for this location is 10 meters.
Corrected coordinates N34.29037 W114.30234 taken at remains of mining structures by Richard Muster in the year 2010 using an Ashtech MM6 device.
This property was examined in conjunction with the mineral appraisal of the Whipple Mountains Wilderness Study Area (Bureau of Land Management) in 1980. Backup information can be found in the WFOC mineral property files.
The ore body strikes N40W and dips 55W. Ore body No. 1 is tabular in a shear zone. Ore body No. 2 is irregular in forma and is a replacement body. The primary mode of origin was hydrothermal activity. Primary ore control was fracturing and the secondary control was faulting. Wallrock alteration is moderate (silicification). Local rocks include Tertiary volcanic flow rocks, unit 16 (Northern Mojave Desert).
U.S. Bureau of Mines property report for this locality lists production for the period 1953 to 1955.
