Sandspring Announces Significant Increases in Life of Mine Grade and Cash Flow; Reduces Initial Capex for Toroparu Project

TORONTO, ONTARIO--(Marketwire - Jan. 30, 2012) - Sandspring Resources Ltd. (TSX VENTURE:SSP) ("Sandspring" or the "Company") is pleased to announce it has completed an updated NI 43-101 mineral resource estimate (the "Updated Resource Estimate") and an updated NI 43-101 Preliminary Economic Assessment (the "Updated PEA") for its 100% owned Toroparu Gold Property ("Toroparu") in Guyana. The Updated PEA is preliminary in nature and includes Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the results of the Updated PEA will be realized. All currency amounts in this press release are denominated in United States Dollars ($) unless otherwise noted.

• Mining of 1.0 million ounces gold at an average grade of 1.2 g/t and 101 million pounds copper at an average grade of 0.18% from the fresh rock mining operation over the first five years of operation.
  
  
• $750 million cumulative cash flow during first five years of production at December 31, 2011 three-year trailing average gold price of $1,255/oz.
  
  
• Pre-production capital costs of $482 million through development of more capital efficient operation for the first five years of mine life.
  
  
• Average cash costs including royalties of $450/oz. gold (net of copper credits) in first five years of operation and $600/oz. gold (net of copper credits) over the 14-year mine life.
  
  
• Mining of 4.0 million ounces gold from fresh and saprolite mineralization at an average grade of 1.0 g/t Au over a 14-year mine life at 4.1: 1 strip ratio, and 5.0 million ounces gold over 22-year life of project.
  
  
• Definitive Mineral Agreement signed with government of Guyana on November 9, 2011, the terms of which have been incorporated into the Updated PEA.
  
  
• Environmental authorization reviewed by Guyana Environmental Protection Agency with no fatal flaws found; and final approval is pending.
  
  
• Open pit operations anticipated to commence in 2015.
  
  

In commenting on the study update, Richard Munson, CEO of Sandspring stated,

"The Updated PEA reflects the results of various engineering tradeoff studies the Company has conducted as part of the ongoing pre-feasibility engineering program conducted by SRK, Jacobs Minerals Canada and P&E Mining Consultants Inc. The higher-grade starter pit scenario has attractive economics that serve to begin the process of unlocking the full potential of Toroparu and Sandspring's holdings in Guyana. The robust financial results highlight the viability of the project and the various build-out options available for the development of the large resource base defined at Toroparu. The Updated PEA indicates life of mine after-tax free cash flows of approximately $1.2 billion at an attractive rate of return while reducing the up-front capital investment required in developing the deposit, all without compromising our ability to expand the project to beyond 30,000 tpd. Drilling conducted since September 2011 which has not been included in the PEA looks promising and could add to the growing resource and potential mine development. The Updated PEA will serve as the basis for further detailed engineering and we look forward to rapidly advancing the Toroparu project in 2012."

The Updated PEA defines a multi-step development of mining and milling capacity from a conceptual mine plan that is focused on higher grade mineralization located in the main east zone of the deposit. The plan is based on an initial mine capacity of 90,000 tpd and mill capacity of 18,000 tpd. Mine expansion begins in year four, ramping up to 175,000 tpd by year six. Mill capacity is scheduled to expand from 18,000 to 33,000 tpd in year seven, and run at 30,000 tpd after saprolite mineralization is mined out in year twelve. Pre-production capital expenditures of $482 million are repaid from internal cash flow within the first 4.7 years of production, and reinvested in the expansion of capacity for the transition to larger resource development without compromising the strong financial results obtained in the 2011 PEA.

The Updated PEA is based on the Updated Resource Estimate that incorporates 110,000 metres of drilling data in 181 diamond drill holes, including 40,320 metres of drilling conducted from January 1, 2011 to September 11, 2011.

The Updated Resource Estimate and Updated PEA have also indicated the following:

• 72% increase in measured and indicated resources to 6.0 million ounces gold contained in 241 million tonnes of mineralized rock at an average grade of 0.78 g/t gold using a higher cut-off grade of 0.28 g/t Au.
  
  
  
  
• An inferred resource of 4.0 million ounces of gold contained in 179 million tonnes at an average grade of 0.69 g/t gold using a cut-off of 0.28 g/t gold including replacement of 2.5 million ounces gold converted to the Measured and Indicated category.
  
  
  
  
• $2.6 billion life of mine operating and $1.7 billion pre-tax free cash flow at three-year trailing average gold price of $1,255/oz. effective December 31, 2011.
  
  
  
  
• Pre-tax and post-royalty net present value (discounted at 5%) of $805 million and pre-tax internal rate of return of 21%.
  
  
  
  
• After tax net present value (discounted at 5%) of $540 million and after tax internal rate of return of 18%.
  
  
  
  
• 90% weighted average gold recovery over a 14-year mine life yielding 3.7 million ounces of gold at a rate of approximately 255,000 ounces per year, and 88% weighted average gold recovery yielding 4.4 million ounces over the 22-year project life.
  
  
  
  
• By-product copper production of 192 million pounds at an average grade of 0.11% Cu and 74% mill recovery over 14-year mine life at average annual production rate of 13.7 million pounds of copper per year, and 262 million pounds at an average grade of 0.09 % Cu and 71% mill recovery over the 22 year project life.
  
  

• 28% increase in potentially mineable Measured and Indicated fresh rock gold resource to 3.3 M oz. Au from 2.6 M oz. Au in 2011 PEA, and 18% increase in life of mine average fresh rock grades to at 1.07 g/t from 0.91 g/t Au.
  
  
  
  
• 32% improvement in potentially mineable average gold grades for fresh rock to 1.17 g/t Au from 0.89 g/t Au in 2011 PEA over first six years of production.
  
  
  
  
• 105% increase in potentially mineable Measured and Indicated saprolite gold resource to 160,000 oz. Au from 78,000 oz. Au in 2011 PEA.
  
  
  
  
• 30% decrease from 2011 PEA in pre-production capital costs to $482 million (based on 15% contingency included to both studies) as a result of a smaller scale, more capital efficient operation for the first six years.
  
  
  
  
• Pre-tax and pre-royalty 5% net present value of $1,050 million vs. $850 million in the 2011 PEA (pre-tax and pre-royalty) based on operating and capital cost escalations experienced since the 2011 PEA, including higher equipment costs and 15% capital contingencies, increased heavy fuel oil costs to $100/bbl. from $70/bbl., and industry and local wage escalations.
  
  

Updated Resource Estimate

The Updated Resource Estimate for the Toroparu gold deposit is based on an additional 40,320 metres of drilling in 87 core boreholes drilled from January to September 11, 2011 targeting the existing resource area as infill with the objectives of i) improving the confidence in the geologic continuity of the mineralization, ii) providing better delineation of the continuity of higher grade mineralization within the east main domain of the resource area, and iii) identifying extensions of the existing gold mineralization envelope through step-out drilling.

The Updated Resource Estimate incorporates 110,000 metres of drilling data in 265 diamond drill holes of which 181 diamond drill holes were utilized in the Updated Resource Estimate. All remaining data in the database were not in the area modeled for the resource estimate. A total of 123,003 metres from 273 boreholes have been reported from Toroparu to date. A surface drill map is available through the following link: http://media3.marketwire.com/docs/SSP3001PEASurfaceMap.pdf.

The Company's next mineral resource update is expected to include additional expansion and infill drilling conducted from September to December 2011, targeting the conversion of remaining Inferred resources within the potentially mineable portion of the resource and the continued delineation of higher-grade mineralization within the main east zone for incorporation into the Company's pre-feasibility study.

Potentially Mineable Portion of the Resource

The Updated PEA is based on an updated potentially mineable portion of the resource summarized in the table below.

Production Schedule

Drilling and exploration success in 2011 identified higher grade mineralization in the central area of the main east zone of the project allowing for a production schedule that focuses on mining the higher grade mineralization in earlier years while stockpiling lower grade mineralization to be processed at the end of the open pit operation.

PEA Parameters

Based on the revised mine plan to facilitate the higher-grade startup scenario, the daily mining rate and the concentrator rate are ramped up over a six-year period from 90,000 to 175,000 tpd and from 18,000 to 33,000 tpd, respectively. The expansion is financed from operating cash flow in years 4-6 providing the Company with additional financing flexibility not available under the development plan in the 2011 PEA.

Areas of Upside Potential in Projected Financials

There are a number of areas that have the potential to positively impact project economics as the company continues to develop the project through feasibility and into production, including:

• The development of the larger resource potential currently defined at Toroparu that would be made possible through continued expansion of the potentially mineable resources;
  
  
  
  
• Incorporation of results from the ongoing pre-feasibility infill drill program received after the September 11, 2011 cut-off date. This drilling has the potential to expand the continuity of higher grade mineralized lenses within the deposit as highlighted by several recent press releases reporting infill drill results;
  
  
  
  
• Lower long-term operating costs derived from the development of western Guyana's hydroelectric power generation potential;
  
  
  
  
• The addition of silver as a payable metal once sufficient assay work is complete to define the extent of this potential by-product metal; and
  
  
  
  
• The improvement in metallurgical recoveries for both gold and copper in the flotation process utilized in the early stages of development of the property, and a possible improvement in gold recovery economics from leach process optimization as the amount of by-product copper in the mill feed is reduced in later years of the mine life.
  
  

Note about Resource Definitions

Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. Environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues may materially affect the estimate of mineral resources. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
