Sandspring Resources Ltd is a Canadian-listed junior gold mining company leading the responsible development of South America`s emerging western Guyana gold district. Focused on bringing into production its 100%-owned 4.1 million ounce Toroparu Gold Project, Sandspring continues to explore its 98,214-hectare concession with the aim of realizing the geologic potential of this highly prospective, mining-friendly jurisdiction.

This facility is expected to process an initial throughput of 19,000 tons per day, and increase to 22,500 tons per day in its fourth year of production.
