Geologic province: Borden Basin
Commodities: Zn; Pb; Ag
Mineralization styles: massive replacement
Geological ages: Mesoproterozoic (host rocks)
Ordovician (mineralization)
Tectonic setting: continental rift (host rocks)
Host rocks: (1) sedimentary; carbonate; Depositional setting: Shallow-water carbonates
Individual lithologies:dolostone
Host rock stratigraphy:Society Cliffs formation
Mineralogy: pyrite, sphalerite, galena, dolomite
Qualified comments: (Applies to: regional geology) The deposit is hosted by Mesoproterozoic rocks of the Bylot Supergroup that rest unconformably on the Mary River Group. The strata have been folded into broad open folds with N-S aves, and these are cut by a series of long-lived E-W trending normal faults. The sultphide mineralization is associated with these faults.

(Applies to: mineralization) Sherlock et al. (2004) present a a series of arguments, including Ar-Ar age dating as summarize by Paradis et al., 2007, p 193, to suggest that the mineralization was Ordovician in age.
