Information leading to the delineation of this focus area

Basis for focus area Tungsten veins outline from USMIN location polygon NV00136.
Identified resources Identified resources and historical production of tungsten.
Production Scheelite Chief mine (1916-1956): 107,830 short tons WO3 (Stager and Tingley, 1988).
Status Past mining.
Estimated resources Scheelite Chief mine (1943): Indicated resource of 5,600 metric tons with a grade of 0.6% WO3 for a calculated contained of 33 metric tons W; Inferred resource of 15,000 metric tons with grade of 0.71% WO3 for a calculated contained of 86 metric tons W; Measured resource of 1 1944), 100 metric tons with grade of 0.75% WO3 for calculated contained of 6.5 metric tons W (Lemmon, 1944).
Geologic maps Rowley and others (2017), scale 1:250,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Scheelite occurs in ore shoots in quartz veins that cut through Cambrian limestone.
Deposits Scheelite Chief mine (MRDS dep_ids: 10037325, 10223428; USMIN Site_ID: NV00135), Canary Yellow mine (MRDS dep_id: 10246972), Everett mines (MRDS dep_id: 10046920), Hilltop mine (MRDS dep_id: 10197977), Lone Buck prospect (MRDS dep_id: 10046919), Oriole mine (MRDS dep_id: 10037324).
Evidence from mineral occurrences MRDS; USMIN.
Geochemical evidence Veins consist of quartz and calcite with some scheelite, and in spots, traces of tetrahedrite, galena, and powellite (Lemmon, 1944).
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments Scheelite occurrences are in veins or stockworks with quartz or calcite, or both, as gangue.
Cover thickness and description Exposed at surface.
