Sandspring Reports Additional Higher Grade Drilling Results From Toroparu; Expects Announcement of Updated Resource Estimate and Updated Preliminary Assessment Results in December 2011

TORONTO, ONTARIO--(Marketwire - Nov. 23, 2011) - SANDSPRING RESOURCES LTD. (TSX VENTURE:SSP) ("Sandspring" or the "Company") is pleased to announce further results from its 2011 expansion and infill-drilling program at the Toroparu Gold Deposit in the Republic of Guyana, South America ("Toroparu").

Highlights include:

  • 241.5m of 1.32 g/t Au including 67.5m of 2.31 g/t Au in TPD 252A
  • 300.0m of 1.06 g/t Au (0.17% Cu) including 120m of 1.58 g/t Au (0.20% Cu) in TPD 255
  • 213m of 1.14 g/t Au (0.17% Cu) in TPD 259
  • 225m of 0.95 g/t Au in TPD 273

(See details in Table 1)

Results reported are from the on-going infill drill program targeting higher grade mineralized lenses within the Main East Zone of Toroparu that include holes drilled along strike and down plunge, TPD 252A, and holes drilled adjacent to, and cross cutting, the higher grade lenses, TPD 255, 259, and 273. Results from this infill program continue to demonstrate the continuity of elevated gold grades within and adjacent to the previously defined higher-grade lenses (Figures 1 and 2).

Results from step-out drilling in drill hole TPD 265, located south-east of the currently defined resource area (Figure 1), together with several other reported mineralized intercepts grading in excess of 1.0 g/t Au over widths of more than 10 meters indicate the potential to extend known gold and copper mineralization along strike to the southeast.

The results of the 2011 expansion and infill-drilling program, which are being reported as received, will form the basis of an NI 43-101 compliant Updated Mineral Resource Estimate for the Toroparu Deposit prepared by SRK Consulting (U.S.) Inc., Lakewood, Colorado, and Updated Preliminary Economic Assessment being prepared by P&E Mining Consultants Inc., Brampton, Ontario. These reports will be based on 100,235m of deposit specific drill data through drill hole TPD 265 with results expected to be announced in December 2011.

Werner Claessens, VP Exploration states... "We continue to obtain strong drill results from the core zone of the Main East Area of the Toroparu Deposit. This is the final set of drill results that will be released prior to a restatement of the mineral resources. We are encouraged by the continued expansion of these higher-grade mineralization features which have the potential to improve the overall quality and size of the resource. In addition, drill hole TPD 265 continues the series of encouraging results from expansion drilling to the southeast of the current resource area, opening the possibility to extend the resource in this direction. We look forward to updating the results of the previous mineral resource estimate, based on 63,614m of drilling with results based on 100,235 metres drilled through TPD 265, as well as the recalculation of the project economics based on this revised resource estimate. Together with the recently signed Mineral Agreement with the Government of Guyana, we expect the definition of this world-class resource to help propel the project toward full feasibility and development."

Results from Holes TPD 251-274 represent an additional 12,441m of diamond core drilling within the Toroparu Deposit area. A total of 60,666m of results has now been reported from the 2011 Drill Program; with a total of 131,385m reported from Toroparu.
