Other/historical names associated with this locality:
Kamff claims; Best Bet; Ida Mae group
A former Au-W-Ag-Pb-Cu occurrence/mine located in secs. 19, 20, 29 & 30, T14N, R18W, G&SRM, in the Dutch Flat area, SW Mohave Mountains, on Bureau of Land Management administered land. A mine comprised of 23 claims (Kamff claims). Owned by A.V. Kampff, Arizona (1955). This mine was started about 1917 and operated 1912 to 1959. The USGS MRDS database stated accuracy for this locality is 1,000 meters.
Mineralization is a polymetallic deposit hosted in fissile biotite schist and gneiss. The ore body strikes N28W and dips 60SW at a width of 0.46 meter and a length of 304.8 meters comprised of stringers, short pods and lenses in 5 veins that are narrow quartz veins containing gold, scheelite and a little wolframite in stringers, short pods and lenses. 2 principal veins were worked intermittently on a small scale since 1917. A little scheelite was recovered from time to time. Associated rocks include Late Cretaceous-Neoproterozoic mafic intrusive rock / granite. Local rocks include Early Proterozoic metamorphic rocks.
Workings include surface and underground openings with an overall depth of 41.15 meters and comprised of 11 adits from 50 to 350 feet long, a few crosscuts, shafts, small stopes and shallow winzes. A 10-ton/day capacity mill was erected on the property.
Production statistics: Year: 1941; ore (estimated): ^3.11 weight percent WO3. Year: 1942: ^6.73 weight percent WO3. Production was a small tonnage of ore produced for many years.
