| Basis for focus area |
Outline of Be occurrences in the Priest River area of northwest Idaho and adjacent areas to the west in northeast Washington based on MRDS and state databases. Polygon in Washington is restricted to likely area of occurrence by the Blickensderfer Quartz Monzonite intrusion. |

| Geologic maps |
Miller and others (1999), scale 1:250,000; Miller and Burmester (2004), scale 1:100,000; Miller (1974), scale 1:62,500. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
The Jurassic Similkameen pluton is a felsic intrusive with associated Cu-Au-Mo porphyry type deposits. The deposits seem to grade with Mo being at the lower elevation area (possible skarns?) and Au-PGE found in placers with undiscovered sources potentially at higher elevation. |
| Deposits |
Idaho: Lakeview prospect (MRDS dep_id: 10093425), L and M prospect (MRDS dep_id: 10069982), State Line occurrence (MRDS dep_id: 10073376); Washington: Silver Plume beryl prospect (MRDS dep_id: 10277619), Dutton prospect (MRDS dep_id: 10301486). |
