| Basis for focus area |
Mining district boundaries from McLemore (2017). |
| Identified resources |
Historical production of barite, fluorite, and manganese. |
| Production |
Between 1918 and 1939, 16,000 tons @ 45% Mn produced mostly from the Manganese Valley mine; fluorite production was 13,428 tons (https://geoinfo.nmt.edu/staff/mclemore/documents/barite_fluorite.xls). |
| Status |
Past mining. |
| Estimated resources |
Unknown. |
| Geologic maps |
New Mexico Bureau of Geology and Mineral Resources (2003), scale 1:500,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
Epithermal fluorite and manganese veins along faults in fanglomerate and Tertiary volcanic rocks. |
| Deposits |
Manganese Valley mine (MRDS dep_id: 10067834), Luna mine (MRDS dep_id: 10009806), Killion vein claims (MRDS dep_id: 10062718). |
| Evidence from mineral occurrences |
MRDS; McLemore and others (2005). |
| Geochemical evidence |
Ore minerals are hollandite and psilomelane; gangue minerals include calcite, barite, and quartz. |
| Geophysical evidence |
No data. |
| Evidence from other sources |
Unknown. |
| Cover thickness and description |
Deposits typically shallow. |
