Upper Canada Mine (Past Producer)
MAIN METALS: Au, Ag
LOCATION: Approximately 9 miles east of Kirkland Lake, 1^ miles west-southwest of Little Larder Lake, in central Gauthier Township. All claims patented. No.1 Shaft in claim L6314; No.2 Shaft in claim L6321. Exploration shafts in claims L6316, L15584, and L15585. Latitude 48.140 , Longitude 79.820 . Map reference: ODM 50c, Township of Gauthier.
GEOLOGY: In the vicinity of the mine workings, east- northeast-trending Timiskaming metavolcanics (trachytic breccia and agglomerate) are overlain by Timiskaming metasediments (greywacke and con glomerate) on the north limb of a major syncline. These rocks are intruded by Algoman porphyry bodies and later diabase dikes. Much of the pro perty is covered by sand and swamps. The o re bodies occur along a wide zone of schisto sity which strikes east-northeast through the centre of the property. The core of this zone is occupied by the Upper Canada “break”, a system of narrow gouge-filled fractures in highly altered tuff, trachyte, trachyte porphyry, and syenite porphyry. Alteration consists of carbonatization, sericitization and sili cification. Gold occurs in relatively late fractures in silicified zones and pyrite.
ECONOMIC FEATURES: The orebodies occur in six vertically dipping main vein zones: L, H, B, C, M and K. The “L” zone, striking east and having an average length of 1,800 feet, was the strongest and most productive ore zone in the mine. It is con tinuous from surface to the deepest level of the mine.
OWNERSHIP: Upper Canada Resources Limited.
Early 1920s: Surface trenching.
1928: Surface work, shaft (Upper Canada No.1) to 134 feet, and some lateral development on the 125- foot level by East Main Gold Mines Limited. This work resulted in the location of the “M” zone.
1936-1941: “H” zone located by surface diamond- drilling. No.1 Shaft deepened to 1,000 feet with levels at 125-foot intervals by Upper Canada Mines Limited. “L” zone located by surface diamond- drilling. To develop this, No.2 Shaft (2,900 feet west of No.1 Shaft) was sunk.
1941-1972: Levels opened from No.1 Shaft to a depth of 3,625 feet; subshaft below No.1 reached a depth of 6,296 feet. No.2 Shaft reached a depth of 1,877 feet. Drifting, crosscutting, and raising totalled 170,364, 44,399, and 52,313 feet re spectively. Salvaging completed and mine closed in 1972.
