| Abstract | The Geological Survey of Canada conducted a study around the ultramafic-associated Ni-Cu deposits in the northern Thompson Nickel Belt, Manitoba, Canada to document the indicator mineral and geochemical
signatures of the deposits in till. Samples used in this study include archived till collected in 1996 and till and bedrock samples collected in 2005 and 2006. Ni-Cu mineralization indicator minerals identified in the study include pentlandite,
pyrrhotite, sperrylite, chalcopyrite, pyrite, millerite and arsenopyrite. Indicators of potentially fertile ultramafic intrusions include chromite, Cr-diopside, forsterite, enstatite and Cr-corundum. Till geochemical pathfinder elements identified in
this study include Ni, Cu, Pd, Pt, Co, As, Cd, Ag, Sb, Bi, Se, S, and Te. Six anomalous till samples from remote locations outside the Belt contain significant elevated concentrations of pathfinder elements and warrant further investigation. The
Laurentide Ice Sheet flowed SW across the belt and subsequently W and exploration along the belt and in the surrounding terranes should consider both the older southwest and younger westward ice flow events when interpreting and following up till
mineralogical and geochemical results. |
