The property lies within the Michipicoten greenstone belt, which is part of the Wawa subprovince and Superior province of Archean age. The Michipicoten greenstone belt is approximately 140 km long by 45 km wide. The property is stratigraphically positioned in the upper portion of the Wawa Assemblage capped by pyrite-bearing iron formation outcropping in the Morrison and Pine zones.
A 30 km long and 4.5 km wide northeasterly trending, structurally deformed zone, called the Goudreau Lake Deformation Zone (GLDZ), occurs between the two assemblages. Including its subsidiary splays, the GLDZ is believed to be the main control on gold mineralization for the area. East-northeast striking, steeply dipping, sub-parallel zones of gold mineralization are present within the quartz sericite-pyrite-carbonate alteration of the GLDZ. North trending diabase dikes crosscut all stratigraphy.
