Formerly: Yates Mine, Otter Lake, Huddersfield Township, Pontiac Co., Québec, Canada

The deposit was originally worked for phlogopite and fluorite in 1906-1907 by the Calumet Mica Co. and later by Mr.A.G.Martin of Ottawa. The workings consisted of a few pits, the deepest measuring 20 feet. In 1943-44, Twin Valley Prospecting Syndicate mined 18 tons of fluorite from the deposit. In 1950 Mr.J.M.Yates discovered the presence of a radioactive mineral, uranothorite, and Yates Uranium Mines Inc. was formed to develop the property. Development consisted of a 300 ft adit, 2 open cuts, and diamond drilling.
