Pepegoona West
South Australia, Frome Basin (Beverley North), Australia
UraniumU
- Type
- Sand-hosted roll-front uranium
Roll-front uranium deposit in Eyre Formation sands (Palaeogene), Frome Basin, mined by in situ recovery (Heathgate Resources). 236U produced in situ by neutron capture on 235U: 236U/238U of the order of 10⁻¹², higher in the most U-rich samples, with deviations linked to mineralogy and water (Murphy et al., 2015). Only groundwater where 236U was detected (well PW0061 in ore above 1 % U). Coordinates of well PW0061 (GDA94, zone 54) converted to degrees.
