Advanced geophysical methods including high-resolution seismic surveying and novel borehole logging techniques have been launched at Heathgate to better quantify both hydro(geo)logical and geochemical conditions that determine the feasibility of in situ recovery (ISR) from sedimentary-hosted uranium. This data is the input to hydrological and reactive transport modeling to optimize well-field design and performance with regard to ore-lixiviant contact and leaching chemistry. The redox puzzle is solved for specific deposit characteristics by a new, practicable kinetic leach model providing control criteria for optimized recovery.
