Cardiff is located in the geological area of the
Grenville Province and has a unique combination of underground minerals. Cardiff opened in 1862, and was one of nine townships purchased by the
Canadian Land and Emigration Company. Early settlers included Mr Armstrong, Mr George Patterson, and Mr Joseph Dunlop. Larger numbers of British settlers arrived in 1870, with the population reaching 31 in 1873, and 137 by 1883. Uranium was first discovered in the area of Cardiff in 1922 by W. M. Richardson. His find was first called "the Richardson deposit" and later "the Fission property," later the
Fission Mine.
Bicroft and
Dyno were more successful uranium mines, operating from 1957 to 1963. == Facilities ==
