Abstract
An indicator mineral study was conducted within the Pine Point Mississippi Valley-type (MVT) district in Northwest Territories to document the abundance, morphology, size and, chemistry of the indicator minerals present in the deposits and in till down-ice of the deposits. Till and bedrock samples for this study were collected in 2010 and 2011. Heavy mineral concentrates (specific gravity >3.2) were isolated from till samples and indicator minerals were picked from this fraction. Indicator minerals identified for the Pine Point MVT deposits include sphalerite, galena, smithsonite, cerussite, and pyrite. Sphalerite and galena are the most useful indicator minerals because they are the most abundant in ore and till samples down-ice and they are sufficiently physically robust that they survive glacial transport.
