| Abstract | The Geological Survey of Canada conducted a till compositional study around the komatiite-associated Ni-Cu deposits in the northern Thompson Nickel Belt, northern Manitoba, to document the multi-element
geochemical signature of the deposits in the <0.063 mm fraction of till. Samples used in this study include archived material collected in 1996 and samples collected in 2005 and 2006. The Laurentide Ice Sheet flowed across the Thompson Nickel Belt
southwestward and subsequently westward, and striations from both ice-flow events are readily apparent on outcrops along the Belt. Exploration along the Thompson Nickel Belt and in the surrounding terranes should consider both the older southwest and
younger westward ice-flow events when interpreting and following up till geochemical results. Till geochemistry of the <0.063 mm fraction is a useful tool for Ni exploration in the region. Pathfinder elements identified in this study for the <0.063
mm till fraction include Ni, Cu, Pd, Pt, Co, As, Cd, Ag, Sb, Bi, Se, S, and Te. This multi-element signature is similar to those identified in till for other Ni-Cu-PGE deposits. Pd:Pt ratio >3 offers further discrimination of significant till
geochemical anomalies. Six anomalous till samples from remote locations outside the Ni Belt contain significantly elevated concentrations of, in various combinations, Pt, Pd, Cu, Cr, Mo, Sb, Bi, and Fe, as well as Au. These anomalies warrant further
investigation. |
