Exploration and Mining History

Originally discovered by W.M. Richardson in 1922. A pit was worked where large uraninite crystals were extracted. 1923: Charles Baycroft opened a 9-m trench near the Richardson pit. 1929 to 1931, subsequent exploration was carried out from a shaft and a number of pits and trenches. 1931-1932: International Radium and Resources Limited built a mill and made test runs in 1933. 1946-1948 & 1955: Fission Mines, Limited performed further surface exploration.
