Sandspring Resources Ltd. (TSX.V: SSP) is a publicly listed Canadian-junior gold mining company with gold assets located in both the Cuyuni-Mazaruni District of Guyana and the Segovia Mining district of Colombia. Sandspring or the "Company" has a long-term focus to develop its 4.5 million-ounce Toroparu Gold Project with near term production anticipated from the historic Guía Antigua Mine located in Segovia, Colombia.
The Toroparu Gold Project will mine gold, silver, and copper from the Toroparu, SE Zone, and Sona Hill deposits. The Toroparu and SE Zone disseminated gold deposits occur within a 2.7 km mineralized corridor that varies from 200m to 400 m wide and from surface to 400 m in deep, and Sona Hill vein deposit, within an 800 m long x 300 m wide area 4.9 km east of Toroparu. Ore from these deposits will be mined as conventional open pits and processed in leaching and flotation circuits to produce both gold doré bars and gold-bearing copper concentrates. Current project design includes 10 years of gold production from a 4.2 million ton per year carbon-in-leach (CIL) processing facility, and an additional 14 years of gold, silver, and copper production from an 8.4 million ton per year facility expanded to include a 4.2 mtpy flotation concentrator.
Ultimately, Sandspring's goal is to develop the exploration potential of the areas surrounding it's Toroparu Gold Project and develop district-scale operations in western Guyana. Western Guyana's gold district is located within the greater Guiana Shield, the northern segment of the Amazonian Craton and dismembered portion of the West African Craton.
More than 30 gold deposits are in production in the West African Craton portion of this region; a result of systematic exploration of the Paleo-Proterozoic volcano-sedimentary belts located within its boundaries. Giant gold deposits including Las Cristinas, Las Brisas, and Choco in Venezuela were also discovered through systematic exploration of these belts in that part of the Guiana Shield.
The volcano-sedimentary belts of Guyana share the same geological history as those of the Venezuelan and West African Shields, and, despite the large deposits discovered to date, Omai, Aurora, and Toroparu, remains largely unexplored. It is believed by many experts that with sufficient systematic exploration, the Guiana Shield will yield additional major gold deposits on a scale of its neighboring regions.
