Surficial geological mapping of the Pine Point region records three, possibly four, directions of ice flow. Dispersal of metal-rich till was primarily to the north and west indicating that at least the oldest ice flow trajectory was in contact with mineralized bedrock. This metal-rich till includes indicator minerals (sphalerite, galena, pyrite and smithsonite) and pathfinder elements (Zn, Pb, Fe, Cd, S and Tl). Dispersal of indicator minerals and pathfinder elements are strongest in the direction of the oldest ice flow trajectory immediately down ice of the deposit and are detectable at the surface within 500 m of the deposit. Sulphur and Pb isotopes from sphalerite and galena grains in till and bedrock are consistent with a Pine Point provenance.
