GEORGETOWN, GUYANA--(Marketwired - April 19, 2013) - Sandspring Resources Ltd. (News - Market indicators) ("Sandspring" or the "Company") is pleased to announce that it has signed a binding Memorandum of Understanding ("MOU") with the Government of Guyana granting Sandspring the exclusive right to evaluate and develop a hydroelectric power plant on the Kurupung River, approximately 30 miles from its Toroparu Property.

The terms of the five-year MOU contemplate that the hydro-electric facility would be developed on a timeline that supports the conversion of the Toroparu Project to hydro-electric power as mining and processing are expanded in the fourth year of Sandspring's mine plan defined in the pre-feasibility study results released on April 10, 2013.

Rich Munson, CEO, comments:

"The MOU creates the opportunity for Sandspring and an independent power producer to jointly develop a long term alternative power supply for Toroparu and other deposits we believe will be found on our property concession. In addition to the significant benefit that hydroelectric power will provide by reducing operating costs and improving sustainability of the Toroparu Project, the development of a hydro-electric facility in Guyana's Region 7 could provide a significant catalyst for further development of the region's proven mineral potential."

Sandspring Resources Ltd. is a Canadian junior mining company currently in advanced exploration and feasibility assessment of the multi-million ounce Toroparu Gold Deposit in the Republic of Guyana. Visit Sandspring's website at www.sandspringresources.com.
