| Abstract | Exploration for base metal deposits using till geochemistry and indicator mineral methods has been the focus of many studies initiated in recent years. The University of Alberta, Geological Survey of
Canada, Tamerlane Ventures Incorporated, and Teck Resources Limited are examining the indicator minerals and till geochemistry that characterize glacial dispersal from the Pine Point Mississippi Valley-type (MVT) district, Northwest Territories. This
case study documents the clastic glacial dispersal down-ice from the O-28 former
open pit mine.
Aqua regia digestion/ICP-MS analysis of the <0.063 mm fraction of till identify Zn, Pb, Cd, Fe, Tl, S, and Se as the pathfinder elements associated
with Pit O-28 in the Pine Point MVT district. Concentrations of Zn, Pb, and Cd are highest directly down-ice of the subcropping mineralization in the direction of the earliest recorded ice-flow trajectory (~230°). This geochemical signature does not
appear detectable at the surface. This may be due to extensive till cover and dilution by multiple ice-flow trajectories, or due to the
extensive winnowing and reworking of the till surface by glacial Lake McConnell that inundated the region
during deglaciation. |
| Summary | (Plain Language Summary, not published)
This is a data release of the till geochemistry from samples collected under the GEM Tri-Territorial Indicator Minerals Project (2008-1013). It provides
basic geochemical data from research conducted at the old Pine Point Mine site. |
