A Fluorspar-Mn deposit/occurrence located about 1.3 km (4,200 feet) WNW of Twin Peaks. Discovered by Eugene Belcher in 1971.
Mineralization is irregular veins and pods. Ore control was fissures along a fault and alteration was argillization and silicification. Area structures include N20°W-trending fault which also extends SE across the Powell prospect.
Structure: N 20 W Trending Fault Which Also Extends Se Across The Powell Prospect.
Alteration: Argillization, Silicification
Tectonics: Basin And Range
Deposit: This record contains data from record number d011427 by ron worl which has been deleted from mrds. ; info.src : 1 pub lit the host rock on the leta lynn prospect is argillized purple andesite porphyry. A mineralized fault zone about 16 ft wide, striking N 20 W and dipping 80 sw, cuts across the prospect. Rock and vein material in the fault zone are strongly silicified. Fluorspar occurs in irregular veins (8 to 10 in wide) and pods along the n W trending fault. The pods and veins contain coarsely crystalline fluorite, with milky quartz, and minor amounts of pyrite and Mn-oxides. Andesite breccia in the fault zone is partially replaced by finely crystalline fluorite. The fluorite is predominantly white and green with a small amount of blue.
Development: About 3 tons of fluorite ore were sold to bishop bailey in deming in 1972. A fe W percussion holes were drilled on the property in the early 1970's.
Ore(s): Fissures Along A Fault
