Information leading to the delineation of this focus area

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).
Evidence from mineral occurrences MRDS.
Geochemical evidence Unknown.
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments One state lands (mineral lease) all else is private ownership.

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.
