ISR Mining - Uranium One

ISR mining technology was developed independently in both the Soviet Union and the United States in the mid-1960’s. The method was developed to extract uranium from typical roll‐front type deposits (a sub‐type of sandstone uranium deposits) located in water‐saturated permeable sediments that were not suitable for economical conventional mining techniques.
