Key: Mineral matches key element mineralogy of deposit Key element(s) in mineral not listed for deposit (-20% score)
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.
