Sandspring Announces Filing of Preliminary Economic Assessment Report for Toroparu Project

DENVER and VANCOUVER, July 23, 2019 - Sandspring Resources Ltd. (TSX Venture: SSP, OTCQX: SSPXF) (“Sandspring”, or the “Company”) is pleased to announce its filing of the Preliminary Economic Assessment Report (the “PEA” or “PEA Report”) for its Toroparu Gold Project in the Mazaruni-Cuyuni District of Guyana (the "Toroparu Project" or “Project”). The PEA Report was prepared in accordance with National Instrument NI43-101 by SRK Consulting (US) Inc. ("SRK") and has been filed on SEDAR and the Company’s website.

The results of the PEA were announced by the Company in its press release (the “June 4 Press Release”) dated June 4, 2019¹. SRK concludes in the PEA Report that “Given the positive results of the PEA, SRK recommends that the Toroparu Project be advanced to a feasibility study. Given the previous studies already conducted on the Project this could be completed within a 6 to 9-month duration.”

The Toroparu Project has been re-scoped to include the Sona Hill satellite deposit, modification of the Project’s processing strategy to start with gold-only production from a Carbon-in-Leach circuit (“CIL”) for the initial ten years, followed by an expansion of the Project in year 11 to add flotation processing capacity and the streaming agreement with Wheaton Precious Metals International.² The PEA Report summarizes the results of the re-scoping at base case metal prices of US³ $1,300 gold (Au), $16.00 silver (Ag), $3.00 copper (Cu).

The PEA documentation of mining production quantities supercedes and replaces the 2013 Prefeasibility Study (the “2013 PFS”) Statement of Mineral Reserves⁴. The PEA is based on exploitation of measured, indicated and inferred mineral resources while the 2013 PFS is based on the exploitation of proven and probable mineral reserves. Inferred resources from the Mineral Resource Estimate identified in the Company’s September 26, 2018 press release⁵ comprise 5% of the resources used in the production schedule reported in the PEA.

Rich Munson, CEO, stated, “As we noted in the June 4 Press Release, the re-scoping study supports the significant changes to the profile of the Toroparu Project that have occurred since the 2013 PFS was issued. As recommended by SRK, we are now working on final feasibility.”
