In-situ uranium leaching substantially increases the volume of the subsurface from which uranium can be mined and therefore the scope of a uranium exploration program. There are however many limiting factors that restrain the application of in-situ leaching. These factors include formation permeability and porosity, the chemistry and hydrology of the interstitial fluids, host-rock and ore mineralogy, and the depth to the deposit. A knowledge of these factors is essential in any exploration program where the target is an in-situ leachable orebody.
