Exploration History

1955: Exploratory drilling 1955-6 indicated reserves of 5077880 tons grading 0.109% U3O8/ton (no dilution) and a further potential of 4000000 tons (no dilution). 1956 2 shafts and 3300 ton mill were started. The No.1 Shaft is a 3 compartment shaft to 3344 feet, and the No. 2 Shaft is a 2 compartment to 2907. Milling commenced in 1958. Stanrock Uranium Mines Ltd. pioneered the bacterial leaching process for Uranium, initially in conjunction with standard mining, and since August 1, 1965 all production from the mine has been by this method. In 1965 alterations were made to the extraction circuit to permit recovery of rare-earth concentrate. 1970: Mining operations suspended. 1978: Mine dewatered. 1979: The shafts were improved and deepened.

Geology Comments

Dec 07, 2005 (G Bennett) - The main ore bed at Stanrock is 10 feet thick and has generally been mined over a width of seven feet. The Quirke Thrust duplicates the ore zone over a width of 1000 feet - the hanging wall block being referred to as No.1 bed, the footwall block referred to as No.2 bed. In the eastern part of the mine a No.3 bed was found under the No. 2 bed and several stopes were opened in it. A few diabase dikes cut the ore.
