Sandstorm Gold Announces Increase to Aurizona's Proven and Probable Mineral Reserve to 2.36 Million Ounces

VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 9, 2013) - Sandstorm Gold Ltd. ("Sandstorm") (TSX:SSL)(NYSE MKT:SAND) is pleased to announce that Luna Gold Corp. ("Luna") (TSX:LGC) has completed an update to its Proven and Probable Mineral Reserve estimate at its Aurizona Gold Mine in Brazil ("Aurizona").

Highlights

• Piaba deposit Proven and Probable Mineral Reserve of 2.36 million ounces of gold ("April 2013 Reserve") including 56 million tonnes of ore with life of mine average 1.32 grams of gold per tonne ("g/t")
• New reserve represents 222% increase in Proven and Probable Mineral Reserves when compared to the Piaba July 2010 Reserve statement
• Piaba deposit reserves are contained within Aurizona property which also contains Measured and Indicated Mineral Resources of 3.63 million ounces of gold with an Inferred Mineral Resource of 1 million ounces of gold (as announced on March 14, 2013)
• The Piaba deposit remains open along strike and at depth. In addition, the brownfields exploration potential at Aurizona is significant as demonstrated by the emerging Boa Esperança, Ferradura, Conceição and Tatajuba deposits
• Based on the April 2013 Reserve and the anticipated completion of Phase I Expansion nameplate processing capacity of 10,000 tonnes per day, Piaba's expected mine life has been extended to 2027 (approximately 15 years). Completion of the Phase I expansion is expected in the fourth quarter of 2013
• As a result of an increase of Piaba's Proven and Probable Mineral Reserves average gold grade combined with the Phase I expansion, the Aurizona average life of mine gold production is now estimated between 125,000 and 140,000 ounces per annum

Sandstorm President and CEO Nolan Watson remarked, "The management team at Luna has done a great job of continuing to expand Aurizona. Today's impressive reserve increase and the continued exploration success point to potential future growth."

Notes:

1. Luna Gold Mineral Resource upgrade effective as at January 29, 2013
2. April 2013 Reserve is based on a gold price of US$1,350 per ounce
3. The model was depleted to the end of month topography December 2012
4. Includes 98% mining recovery
5. Includes 10% mine dilution
6. Includes foreign exchange conversion rate of 1.9 Brazilian Real to 1 US Dollar
7. Break even cut off grades of 0.44 g/t, 0.49 g/t and 0.51 g/t were used for saprolite and laterite, transition and fresh rock ore types, respectively
8. Metallurgical recoveries are included in the cut-off grade calculations and calculated to be 92% for saprolite and laterite, 91% for transition and 91% for fresh rock, respectively
9. Au ounces exclude metallurgical recoveries
10. April 2013 Reserve is presented in accordance with the classification standards established by the Canadian Institute of Mining, Metallurgy and Petroleum
11. The estimates of mineral reserves may be materially affected by geotechnical, environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues
12. The mineral reserve estimate has been prepared and overseen by Qualified Persons Alberto Reyes, Chartered Professional with the Australian Institute of Mining and Metallurgy (AusIMM) and G. Peter Mah, P Eng Ontario, and independently reviewed by Sam Shoemaker, Registered SME Member, Micon International Limited

The updated Piaba resource announced on March 14, 2013 serves as the basis for the April 2013 Reserve which has been estimated assuming a spot gold price of $1,350 per ounce, mining recovery of 98%, and dilution of 10%. These assumptions result in a life of mine strip ratio (waste:ore) of 6.6:1.

Luna is currently undertaking further optimization studies to assess additional improvements to the April 2013 Reserve. These studies include (i) optimizing the life of mine expected operating costs related to the Phase I expansion production rate of 10,000 tonnes per day of ore; (ii) evaluating the possible conversion of the near mine resource deposits Tatajuba, Boa Esperanca, Ferradura and Conceicao with the view of integrating them under the Aurizona Mineral Proven and Probable Reserves; and (iii) the Aurizona Phase II expansion prefeasibility study. The Company is targeting a subsequent reserves update during 2014.
