| 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. |
| Summary | (Plain Language Summary, not published)
Complete documentation of the indicator minerals that that Pine Point Mississippi Valley-Type (MVT) lead-zinc deposit could possibly generate during
glacial erosion. Comparison and reported with results from till samples collected down-ice. This information is applicable for drift prospecting and exploration of MVT style deposits in northern Canada. |
