Information leading to the delineation of this focus area

Basis for focus area Mining district boundaries from McLemore (2017).
Identified resources Historical production of tungsten.
Production Tungsten production was 3,000 lbs of 60% WO3 from 1907-1956 (see https://geoinfo.nmt.edu/staff/mclemore/documents/tungsten.xls).
Status Past mining and exploration; area is near the Picuris Pueblo, which is against mining and has opposed proposed drilling.
Estimated resources Unknown.
Geologic maps New Mexico Bureau of Geology and Mineral Resources (2003), scale 1:500,000.
Geophysical data Rank 4 aeromagnetic coverage (U.S. Geological Survey, 1975); no aeroradiometric coverage.
Favorable rocks and structures Stratabound deposit in a brittle-ductile structural trap hosted by Precambrian quartzite and schists.
Deposits Tungsten mine (MRDS dep_id: 10296834), Copper Hill mine.
Evidence from mineral occurrences MRDS; New Mexico Mines Database (McLemore and others, 2005).
Geochemical evidence Up to 18,935 ppm Sb and 4,400 ppm As (Williams and Bauer, 1995).
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments Near Picuris Pueblo, which is unfavorable to mining this deposit.
Cover thickness and description Variable.
