In the recent E-newsletter by the British Columbia Geological Survey, George J. Simandl released GeoFile 2011-10, providing background information regarding rare metals and rare earth elements in British Columbia. (see GeoFile 2011-10)
The map accompanying the GeoFile is 1:2 000 000 scale and shows the location and geological setting of 106 rare metal and rare earth element occurrences throughout the Rocky Mountain Rare Metal Belt.
The occurrences have been grouped into seven geological categories based on the association between mineralization and host rock or key lithological units. The seven are as follows:
- Carbonatite/syenite-related deposits
- Peralkaline/alkaline intrusion-related deposits
- Pegmatites/granite hosted
- Placers and paleoplacers
- Phosphate-hosted REE deposits
Other rare earth element occurrences such as those in the Wicheeda Lake area were also highlighted. (Companies actively exploring the Rocky Mountain Rare Metal Belt)
Carbonatite/syenite-related deposits appear to be the primary exploration targets for niobium and rare earth element exploration in British Columbia.
