Geology of the 1901 deposit and implications for controls on Cu–Zn–Au VMS mineralization in the Chisel Sequence, Snow Lake arc assemblage, Snow Lake, Manitoba, Canada

Canadian Journal of Earth Sciences, Ahead of Print.The 1901 deposit of Hudbay Minerals Inc. is one of seven Zn−Cu–Au volcanogenic massive sulfide (VMS) deposits in the Lower Chisel Sequence at Snow Lake. Past research suggests that VMS mineralization in the Chisel Lake area occurs at a conformable stratigraphic boundary between the Lower and Upper Chisel sequences (LU–UC). However, our investigation indicates that mineralization occurs below this contact, in a calc-alkaline vol
