Sandspring Presents Drill Results from Holes 81-93 on Stepout; Hole 93 Intersects 110m of 0.90g/t Gold and 0.06% Copper and 56.5m of 1.08g/t Gold and 0.09% Copper

TORONTO, ONTARIO--(Marketwire - Sept. 15, 2010) - SANDSPRING RESOURCES LTD. (TSX VENTURE:SSP) ("Sandspring" or the "Company") is pleased to announce an update on gold and copper assay results from drilling in the area of the Toroparu gold-copper deposit in the Republic of Guyana, South America.

Results from holes TPD081 - TPD093 comprise an additional 7,257m of drilling designed to optimize and expand grade and tonnage parameters of the known NI 43-101 compliant Toroparu gold-copper resource and to test continuity at various step-out locations along strike (Table 1). To view Table 1: Summary of 2010 Drill Hole Composite Assays, please visit the following link: Assay results from a total of 41,659m of diamond drilling have now been disclosed to date on the Toroparu Property. Drill collar locations and hole traces relative to the current NI 43-101 compliant optimized open pit resource model surface contour may be viewed in Figure 1.

Abraham Drost, P.Geo., President of Sandspring states: "A variety of targets were tested on and off-trend during the current phase of drilling. The presence of broad intercepts of gold and copper mineralization, including Hole 93 with two intercepts of 110m of 0.90g/t gold and 0.06% copper and 56.5m of 1.08g/t gold and 0.09% copper underscores the strength and significance of mineralization along strike to the northwest of the current optimized open pit resource model. Resource optimization and exploration drilling continues."

Analytical testing and reporting of quantitative assays was performed independently by Acme Analytical Laboratories Ltd. ("AcmeLabs").
