| 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. |
