ROM characterization - USA

Objective

Define overall hydrogeological framework to allow design of an in-place leaching program on an large ROM operation

Approach

Large scale geophysical reconnaissance and detailed characterization for hydrodynamic parameters. The geophysical evaluation included three-dimensional Electric Resistivity Tomography (ERT) and Seismic Refraction Tomography (SRT)

Results

• Define overall solution distribution and structure within rock pile
• Identify leaching targets and potential point of solution discharge
• Reduced characterization costs
