TORONTO, ONTARIO--(Marketwire - April 14, 2011) - SANDSPRING RESOURCES LTD. (News - Market indicators)("Sandspring" or the "Company") is pleased to announce an update of new gold and copper assay results from its ongoing infill drilling program in the area of the Toroparu gold-copper deposit in the Republic of Guyana, South America.

New gold and copper assay results (summarized in Table 1) are from 6,266m of core drilling holes TPD143 – TPD155 (Figure 1 & Figure 2). The current drill program is 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 Company's March 22, 2011 Press Release of a Preliminary Economic Assessment. Annual production over the first four years of operation is expected to average 310,000 ounces gold and 29 million pounds of copper and an average cash cost of $317/oz. gold, net of copper byproduct.¹

To date a total of 16,975 meters of initial infill drilling has been completed from the recommendations contained in the P&E Mining Consultants Inc. 43-101 compliant Resource Update & Technical Report Nr. 193 signed on October 13, 2010 and posted on www.sedar.com for the upgrade of resources in anticipation of potential full feasibility.

A total of 77,036m of diamond drilling results have now been disclosed on the Toroparu Property.

Recently the company started an exploration drill program with the objective to find further lateral extensions to the existing mineral deposit and/or nearby satellite deposits. Several deep holes are planned as part of this program to explore the deeper parts of the deposit

Abraham Drost, P. Geo., President of Sandspring states "Results from the ongoing infill drill program at Toroparu suggest potential for enhanced grade within the PEA production pit model area as the Company converts Inferred to Measured &/or Indicated resources in preparation for a future resource update and commencement of a Definitive Feasibility Study as recommended by P&E Mining Consultants.

The Company also continues to pursue considerable expansion potential within the newly-defined deposit envelope released in the Company's March 21, 2011 press release and along trend in other areas marked by geochemical, Gradient IP results, and historical alluvial gold workings."
