Electrical resistivity geophysics has been applied on a heap to characterize and monitor changes in saturation after primary and secondary leaching applications. The characterization effort mapped the distribution of high and low resistivity, which can be correlated to low and high moisture content, respectively. Regions of low moisture and high resistivity were assumed to be ineffectively leached during the primary leaching cycle, and were targeted by a secondary leaching application with Hydro-Jex. Hydro-Jex involves the injection of lixiviant at high pressures in a cased well. During the injection, the electrical resistivity was used to monitor the decrease in resistivity. The decrease is directly related to increased saturation. The electrical resistivity monitoring showed how the fluid injected into the heap moved away from the injection well, and demonstrated the effectiveness of the Hydro-Jex technology to reach dry and unleached areas within the heap.
