In September of 2017, HGI conducted a multi-method electrical resistivity, refraction seismic, and gravity geophysical survey at a proposed Tailings Storage Facility (TSF) called the Peg Leg TSF, near Kearny, Arizona. The survey was designed to help answer questions about the depths to bedrock and character of the basin fill in support of a geotechnical feasibility study for the proposed TSF.
