Basis for focus area |
Focus area outlines a cluster of ~10 tungsten occurrences (MRDS records). |
Identified resources |
Past production of tungsten. |
Production |
Blue Grouse mine (1952-1953): about 0.5 tons of concentrate @ 61% WO3 (report of poor recovery at mill; tailings are rich in WO3). |
Status |
Past mining. |
Estimated resources |
Unknown. |
Geologic maps |
Miller (1974), scale 1:62,500; Miller and others (1975), scale 1:62,500. |
Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. Fair-poor gravity. |
Favorable rocks and structures |
Contact area between Precambrian quartz monzonite and schist. |
Deposits |
Blue Grouse Mountain mine (Tungsten King mine) (MRDS dep_id: 10042369). |

New data needs |
High resolution mapping, geochemistry, and geophysics. |
Geologic mapping and modeling needs |
Detailed geologic mapping with alteration focus/geochemistry. |
Geophysical survey and modeling needs |
High resolution aeromagnetic and aeroradiometric survey. Gravity may not be helpful with the similarity to the host/intrusive rock types. |
Digital elevation data needs |
Lidar complete. |
