Jan 30, 2020 (Sheree Hinz) - The Larder Lake "break” represents the faulted contact between Timiskaming metasediments on the north and Keewatin metavolcanics on the south. In the vicinity of the mine workings, the hanging wall of the "break" consists of intensely sheared greywacke. The footwall comprises a highly altered green and brown "carbonate zone", up to 600 feet in width, which contains irregular lenses of talc-chlorite schist and small irregularly shaped bodies of altered syenite intrusive rocks. South of this zone are bedded tuffs. Interbanded with the tuffs, and lying south of them, are mafic lava flows.

Jan 30, 2020 (Sheree Hinz) - The orebodies are of two different types. The carbonate type consists of irregular lenses of gold-bearing quartz stockworks lying with in the highly altered and brecciated carbonate zone. Gold occurs in the free state randomly distributed throughout the quartz. The flow type of orebody consists of lenses of mineralized and silicified flow rock lying in the less altered flows and tuffs south of the carbonate zone. Pyrite mineralization, which is uniformly disseminated throughout the ore zone, contains most of the gold. The average grade of gold (from 1911, 1936-1996) was 0.259 oz/ton Au.
