Dec 07, 2005 (C Salo) - The Sheridan Lake zinc occurrence is within the Peeagowon Assemblage of the Wunnummin Lake Greenstone Belt. Pillowed and massive mafic flows, minor units of oxide- and sulphide- facies iron formation and interbeds of quartzite and felsic turf make up assemblage. The regional Stull Lake - Wunnummin lake fault zone strikes northwest, traversing north of the Sheridan lake zinc occurrences.

Dec 07, 2005 (C Salo) - Sulphide-rich layers in the iron formation consist of po and py, Interbedded with chert. Minor cp, is present it the form of local disseminations and occasional specks within the iron sulphide minerals. Sulphides also occur in places as fracture-fillings and or stringers, blebs, and disseminations within metavolcanics and metasediments other than iron formation.
Sep 12, 2019 (Therese Pettigrew) - DDH 7 reported assays of up to 0.51% Zn and 0.07% Cu over 3.2 feet (1 m) from a mineralized black shale containing 50-60% pyrrhotite and 1% chalcopyrite (Assessment report 53A10SE0004).
