Sandspring Resources Ltd. Reports 388.5 m Intercept of 2.01 g/t Gold and 0.30% Copper in Drill Hole TPD 242 in Expansion of Higher-Grade Mineralization at Toroparu07:00 EST Monday, November 14, 2011TORONTO, ONTARIO--(Marketwire - Nov. 14, 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-Copper Deposit in the Republic of Guyana, South America ("Toroparu").The Company will host a conference call today, Monday November 14th at 11:30 AM EST to address questions regarding the recently signed Mineral Agreement and other developments (call-in details provided at the end of this press release).The current infill program is specifically designed to confirm the extent and continuity of elevated grade along the orientation of higher grade mineralized lenses. These features were identified over the course of 2011 by additional definition drilling and improved resource and geologic modeling (Figures 1, 2, and 3).Intercepts from drill holes TPD 242 and 247, drilled along strike and plunge of these lenses, highlight the extent of higher-grade mineralization located in the central part of the East Main Zone (Table 1). These results confirm our expectations and demonstrate good elevated gold and copper grade continuity and distribution to drill depths of over 600 m.Further analytical results from the other infill holes TPD 248, 248A, 248B, 249 and 250, provide a better understanding of the geological controls and improve the quality and accuracy of the resource modeling.Additionally, the Company is reporting results that include exploration drilling to the northwest and south of the currently defined resource area in holes TPD 239, 240, 243 and 245, as well as step-out and exploration drilling to the southeast of the main resource area in drill holes TPD 238, 241, and 244. Several intercepts in this area, often mineralized over widths of 10 meters or more, indicate the potential to find significant extensions of gold and copper mineralization to the southeast of the currently defined resource area (Figure 1).Table 1: Highlights of Weighted Average Composite Grade Intervals, Drill holes TPD 238-265To view detailed weighted average composite details for all drill holes TPD 238-250 go to: http://media3.marketwire.com/docs/sandspring_table2_nov14.pdf Hole IDFrom (m)To (m)Length (m)Gold (g/t)Cu (%)CommentTPD241186.00207.0021.001.260.31Step out214.50225.0010.501.440.15TPD2420.0097.5097.501.100.29InfillIncl.82.5094.5012.003.000.65126.00514.50388.502.010.30Incl.166.50202.5036.003.070.50Incl.139.50370.50231.002.690.42And450.00514.5064.501.350.13TPD24570.5072.001.503.270.09Exploration244.50247.503.000.930.01TPD246358.50474.00115.501.150.03Infill712.50718.506.003.450.00TPD24749.50126.0076.501.170.40Infill181.50330.00148.502.340.39Incl.219.00223.504.5017.871.83Incl.283.50330.0046.503.060.36And289.50294.004.5018.110.52And309.00315.006.008.780.79345.00370.5024.001.010.07378.00448.5070.501.090.11465.00609.00144.001.390.12643.50673.5030.001.200.05Incl.654.00655.501.5019.3*0.14778.50795.0016.501.770.18823.50840.0016.501.770.18TPD248B391.50408.0016.501.760.01Step out483.00495.0012.002.680.01Incl.493.50495.001.5021.3*0.01TPD249166.50183.0016.501.020.07InfillTPD250456.00469.5013.502.070.00InfillIncl.468.00469.501.5058.4*0.00* All intervals are reported as down-hole lengths and additional information is required to determine true widths.* Gold assay values greater than 12 g/t are top-cut to be consistent with the last reported NI 43-101 resource model.Figure 1: Plan View of Drill Hole Locations TPD 238-250To view "Figure 1: Plan View of Drill Hole Locations TPD 238-250", please visit the following link: http://media3.marketwire.com/docs/sandspring_figure1_nov14.pdfFigure 2: Longitudinal Section - GoldFigure 2 highlights of areas of elevated grade of Au > 1.5 g/t delineated over the course of 2011 infill drill and resource modeling programs, identified as a series of mineralized lenses with an east-west orientation and plunging 45 degrees to the west in the core of the Main East Domain of the Toroparu deposit.To view "Figure 2: Longitudinal Section with Mineralized Gold Lens > 1.5 g/t Au cut off", please visit the following link: http://media3.marketwire.com/docs/sandspring_figure2_nov14.pdfFigure 3: Longitudinal Section - CopperFigure 3 highlights of areas of elevated grade of Cu > 0.1% delineated over the course of 2011 infill drill and resource modeling programs, identified as a series of mineralized lenses with an east-west orientation and plunging 45 degrees to the west in the core of the Main East Domain of the Toroparu deposit.To view "Figure 3: Longitudinal Section with Mineralized Copper Lens > 0.1% Cu cut off", please visit the following link: http://media3.marketwire.com/docs/sandspring_figure3_nov14.pdfWerner Claessens, VP Exploration states... "As we approach the end of the 2011 infill drill program, there is good reason to be satisfied with the results. Our understanding of the geological context of the gold/copper mineralization system at Toroparu has been greatly enhanced and we are working hard to complete the geological model for this deposit. It seems obvious these assay results will improve both the quality and size of the resource. Furthermore, we continue to obtain encouraging results from expansion drilling to the southeast of the current resource area, opening the possibility to extend the resource in this direction. The current phase of infill drilling, when complete, will expand total drilling from the 63,614 m contained in the Company's April 30th2011 Preliminary Assessment to approximately 125,000 metres allowing for an update of the resource model, the economics defined in the Preliminary Assessment, and the definition of a world-class resource that has the potential to be converted to reserve classifications in the upcoming pre-feasibility engineering of the project."Results from Holes TPD 238-250 represent an additional 6,177 m of diamond core drilling within the Toroparu Deposit area. A total of 48,225 m of results has now been reported from the 2011 Drill Program; with a total of 118,941 m reported from the Toroparu Deposit.Analytical testing and reporting of quantitative assays for the results reported in this press release was performed independently by Acme Analytical Laboratories Ltd. ("AcmeLabs"). AcmeLabs is an ISO9001: 2008 accredited laboratory. A system of blanks, standards and duplicates were added to the Toroparu sample stream by the Company to verify accuracy and precision of assay results, supplementing a variety of internal QA/QC tests performed by AcmeLabs.Mr. Brian Ray, P.Geo., Senior Resource Geologist with Sandspring and a Qualified Person under NI 43-101, has reviewed and approved the technical content of this press release.Sandspring will host a conference call for anyone interested in addressing questions to management regarding the Mineral Agreement on Monday, November 14, 2011 at 11:30 AM EST.Conference Call-in Toll-Free Number - U.S. and Canada(877) 407-8033Audio Call-in International(201) 689-8033Anyone not able to participate in the conference call can listen to an audio webcast available for 60 days at: http://www.investorcalendar.com/IC/CEPage.asp?ID=166591.Sandspring Resources Ltd. is a well-funded Canadian junior mining company currently in advanced exploration and prefeasibility assessment of the multi-million ounce Toroparu Gold-Copper Deposit in the Republic of Guyana.
