Tierra Group provided a feasibility-level Tailings Storage Facility (TSF) design for Condor Gold’s La India Project permitting, a planned 2,000 tpd open pit mine in western Nicaragua. TSF embankments used rockfill from the open pit and a geomembrane liner for tailings and supernatant containment. Geotechnical investigation and analyses and water management in a tropical environment presented the greatest project challenges.
