Information leading to the delineation of this focus area

Basis for focus area District boundaries from McLemore (2017).
Identified resources Historical production of gold, silver, and tungsten.
Production Between 1890 and 1951, the White Oaks mining district produced about 152,373 oz Au (Grainger, 1974) and 119,933 lbs of WO3 concentrate with an average grade of 56.18% (Griswold, 1959). The Old Abe mine produced 45,745 oz Au, as well as Ag and W. The South and North Homestake mines produced a combined 50,000 oz Au (Grainger, 1974).
Status Past mining. Recent exploration sampling.
Estimated resources Unknown.
Geologic maps New Mexico Bureau of Geology and Mineral Resources (2003), scale 1:500,000; Rawling and Koning (2011), scale 1:24,000.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Alkaline intrusions.
Deposits Old Abe mine (MRDS dep_id: 10014069), North and South Homestake mines (MRDS dep_id: 10101862).
Evidence from mineral occurrences MRDS.
Geochemical evidence Huebnerite is the W mineral in the district. Gold does not occur with W. Portions of the Old Abe mine dumps sampled in 1922 contained 0.38% WO3.
Geophysical evidence Aeromagnetic and gravity data needed.
Evidence from other sources Unknown.
Comments Important but poorly understood Au, W, and Te(?) deposit.
Cover thickness and description Unknown.
Authors Virginia T. McLemore, Joshua M. Rosera.
New data needs Alteration mapping, detailed mapping of the plutons and dikes in terms of lithology, geochemistry and mineralogy of the veins; geophysics.
Geologic mapping and modeling needs The existing geologic map of White Oaks South by Rawling and Koning (2011) does not include detailed mapping of the plutonic rocks or alteration mapping. White Oaks North has not been mapped. Additional detailed mapping is needed.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric survey.
Digital elevation data needs Lidar in progress.
