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.

Paragenetic Mode	Score
34 : Complex granite pegmatites Unique: Spodumene	100
19 : Granitic intrusive rocks	2
