Tierra Group performed an independent engineering design review of a Cemented Tailings Facility (CTF) and multiple processes and freshwater ponds. Tailings will be mixed with cement at the paste plant and deposited in the CTF along with underground mine development rock. Protecting the robust liner system from haul truck traffic presented a unique challenge. In addition, Tierra Group performed a GISTM compliance audit to inform future TSF planning and corporate governance.

As the EoR, Tierra Group provided a seismic hazard analysis, construction document updates, and general EoR support.
