Jan 28, 2020 (Therese Pettigrew) - The South Sturgeon assemblage is composed of a well-preserved bimodal, subaerial to subaqueous caldera complex hosting several zinc-copper-lead (-gold-silver) VMS deposits that, between 1972 and 1991 produced a total of 20 million tons of ore. The caldera eruptive history consists of subaerial to shallow basaltic shield volcanism overprinted by caldera-forming subaerial to subaqueous explosive felsic eruptions. The volcaniclastic units are principally represented by monomictic felsic lapilli tuffs, tuffs and breccias, and are interpreted as gravitational deposition of volcanic clasts originating from the eruption or from the subaqueous fragmentation of felsic domes. The subaqueous bimodal volcanism was accompanied by seawater infiltration, which triggered a long period of hydrothermal activity, creating optimal conditions for the VMS formations. The mineralization in the South Sturgeon assemblage is mainly composed of sphalerite-pyrite-chalcopyrite-galena-arsenopyritepyrrhotite with magnetite. The mineralization is contained mainly within the stratabound ore, but is also disseminated and in quartz veins beyond the orebody. The Mattabi, F-Group and Sturgeon Lake mine sites represent the primary stratabound massive sulphide deposits, whereas the Lyon Lake and Creek Zone were formed during a later remobilization controlled by northwest shearing (Etienne et al., 2019).
