Information leading to the delineation of this focus area

Basis for focus area Buffalo Canyon is in the Union district in northwest Nye County, east of Gabbs, Nevada. The Buffalo Canyon prospect is defined by an area of exposed gold-bearing quartz veins known as the Everson gold prospect (Quillen, 2017).
Identified resources Historical production of gold and silver and identified resources for gold.
Production The Berlin mine produced about 40,000 oz Au.
Status Past mining and current exploration.
Estimated resources Everson prospect (1990s): 300,000 oz Au, averaging 0.37 to 0.40 g/t Au (Quillen, 2017).
Geologic maps Silberling (1959, plate 1), scale 1:24,000; Wallace and others (1959), scale 1:48,000; Stewart and Carlson (1978), scale 1:500,000.
Geophysical data Inadequate Rank 4 aeromagnetic coverage.
Favorable rocks and structures Siliciclastic, volcaniclastic, and volcanic rocks and minor limestones of the Triassic-aged Knickerbocker Formation were intruded by a series of stocks and dikes of porphyritic to equigranular diorite, quartz diorite, and granodiorite of undetermined age, resulting in ones of biotite and pyrrhotite-bearing hornfels and magnetite skarns.
Deposits Berlin mine (MRDS dep_id: 10044420), Everson prospect.
Evidence from mineral occurrences MRDS; Quillen (2017).
Geochemical evidence Surface geochemistry, petrography and alteration mapping given in Quillen (2017).
Geophysical evidence Unknown.
Evidence from other sources Recent gold mineralization was discovered during a regional stream sediment survey.
Comments Buffalo Canyon is near the historical mining camps of Berlin and Ione in the Union mining district. At the Berlin mine, Au and Ag were extracted from high-grade mesothermal quartz veins and quartz--adularia veins. At the recently recognized Everson prospect, mesothermal quartz veins hosted within Jurassic intrusions have an Au-Ag-(Sb-Pb-As-Cu) geochemical signature (Quillen, 2017).
Cover thickness and description Alteration exposed at the surface.
