Predictive Mineralogy

Possible unrecorded species at Pegmatite No. 7, Coe claim, Bernic Lake, Lac-du-Bonnet area, Manitoba, Canada

This table is based on statistical analysis of other localities containing similar species to the ones found at this locality.

Predicting paragenetic modes of deposit

Green indicates almost certain match based on minerals unique to a certain deposit type. Yellow indicates a possibly poor match, but should not be entirely discounted. Scores > 100 indicate strong confidence.
