Prefeasibility Study for Toroparu Open Pit Gold Project

SRK has previously provided mining consulting services to Sandspring Resources Ltd. (a Canadian-based company) for their Toroparu Gold Project, located in northwestern Guyana. A prefeasibility study for the project was conducted. It called for an open pit mine with twin processing streams, including flotation (copper and gold) and carbon-in-leach (gold), for a combined processing rate of 23,000 tpd and a 15-year mine life.
