TORONTO, ONTARIO--(Marketwire - May 24, 2011) - SANDSPRING RESOURCES LTD. (News - Market indicators) ("Sandspring" or the "Company") is pleased to announce new gold and copper assay results (summarized in Table 1) from a recently completed infill-drilling program at the Toroparu Gold-copper Deposit in the Republic of Guyana, South America.
The analytical results for drill-holes TPD156 - TPD170 comprise the final 6,150 meters of drilling that completes an infill-drill program recommended by P&E Mining Consultants Inc. of Brampton, Ontario (P&E). The infill drill program was designed to better define the geological controls, optimize grade and improve classification of the Inferred Resource contained in the Potentially Mineable Portion of the Toroparu Resource as disclosed in the independent 43-101 compliant Updated Resource Estimate and Preliminary Economic Assessment of the Toroparu Gold-Copper Deposit, Technical Report No. 208, signed by P&E on May 5th, 2011. A total of 19,572 meters of results have now been reported from the completion of the recommended infill-drill program, and 83,186 meters reported on the Toroparu Gold – Copper Deposit.
Following the completion of the infill program in March 2011, exploratory drilling programs focused on testing the potential of the mineralized domains along trend in the Northwest, West-Northwest, and Southeast portions of the Toroparu Deposit area.
The Company is presently drilling with four drills to optimize the Toroparu Resource and to test exploration targets within the 6 km long, west-northwesterly trending structural corridor. A regional sampling and mapping program is ongoing across the Company's larger Upper Puruni Concession with the objective of identifying new targets for drilling.
An additional 60,000m of drilling is planned for the remainder of 2011 for both exploration purposes and preparation of a Definitive Feasibility Study of the Toroparu Resource.

Abraham Drost, P.Geo., President of Sandspring states… "The extensive initial infill drilling program which commenced in October 2010 has produced encouraging results. We anticipate that these results could increase the quantity and quality of the mineral resource ounces of the potentially mineable portion of the Toroparu deposit."
In the 43-101 compliant Preliminary Economic Assessment (PEA) of the Toroparu Deposit contained in Technical Report No. 208, signed on May 5th, 2011, P&E recommended that Sandspring proceed with a definitive feasibility study. The Potentially Mineable Portion of the Resource contained in the PEA included a Measured and Indicated Resource of 2.67 million ounces gold, 253 million pounds of copper and an Inferred Resource containing 1.27 million ounces gold and 89 million pounds of copper (Figure 1).

The mineralized domains that make up the Toroparu Deposit remain open along strike and to depth. A number of the drill holes reported in this press release highlight the potential for expansion of previously modeled Fresh Rock South and Fresh Rock North 1 (N1) Mineralized Domains, as highlighted in Figure 2.
The recently completed infill program together with an additional exploratory drill program in progress will provide sufficient information for modeling the potential expansion of the Toroparu Deposit and could ultimately lead to an Updated Resource Estimate as information is received.
