March 14, 2013
Sandstorm Gold Ltd. (“Sandstorm”) (NYSE MKT: SAND, TSX: SSL) is pleased to announce that Luna Gold Corp. (“Luna”) (TSX: LGC) has completed an independent mineral resource update at its Aurizona Gold Mine in Brazil (“Aurizona”). Aurizona’s measured and indicated mineral resources now total 3.63 million ounces and inferred mineral resources are now 1.04 million ounces, a 15% and 44% increase respectively, from the December 2011 resource update.
The updated resource incorporates an additional 6,933 metres drilled at the Piaba deposit and 7,478 metres drilled at the Boa Esperança, Ferradura and Conceição deposits throughout 2012. A pit optimization exercise was also conducted for the Tatajuba deposit. Measured and indicated gold resources now total 82 million tonnes at 1.38 grams per tonne gold, or 3.63 million ounces gold. Inferred gold resources now total 18.5 million tonnes at 1.74 grams per tonne gold, or 1.04 million ounces gold.
“The Aurizona gold stream is our flagship stream and today’s announced resource update represents additional value for Sandstorm shareholders,” said President and CEO Nolan Watson. “I want to commend Luna for their success to date and we look forward to seeing how the resource grows as exploration continues.”

- Open pit resources (Whittle pit® optimization) are constrained by a 0.30 g/t Au grade domain and stated at the following cut-off grades for Piaba, Boa Esperança, Ferradura and Conceição: Laterite & Saprolite – 0.322 g/t Au, Transition – 0.364 g/t Au and Fresh Rock – 0.400 g/t Au based on a gold price of US$1,500 per ounce, pit slopes of 45o for Laterite/Saprolite/Transition and 55o for Fresh Rock, mining cost of US$1.80/t material moved, process and G&A cost of US$14.00/t (Laterite/Saprolite), US$15.50/t (Transition) and US$17.00/t (Fresh), recoveries of 92% (Laterite/Saprolite) and 90% (Transition/Fresh Rock) and selling cost (transportation, insurance, royalty) of US$30.00/t.
- Open pit resources (Whittle pit® optimization) are constrained by a 0.30 g/t Au grade domain and stated at the following cut-off grades for Tatajuba: Laterite & Saprolite – 0.368 g/t Au, Transition – 0.411 g/t Au and Fresh Rock – 0.447 g/t Au based on the same parameters as outlined in point 1 above plus an additional cost of U$2.00/t for transportation to the Aurizona mill.
- Fresh rock outside pit shell resources are stated at the following cut-off grades for Piaba: 1.50 g/t Au based on a gold price of US$1,500 per ounce, mining cost of US$45.00/t moved, process and G&A cost of US$19.00/t, recovery of 90%, selling cost of US$30.00/t and an additional 1% royalty increase.
- Aurizona topography is current as of October 31, 2012.
- Maptek’s Vulcan v8.1.4 was used in the resource estimation including compositing and grade estimation. Internal waste blocks inside the 0.30 g/t Au grade shell were estimated separately from mineralized blocks using indicator kriging. Mineralized blocks were estimated by the ID3 algorithm.
- Block dimensions are 10m x 5m in the xy plane x 3m on the z axis. Sub-blocking to 1m x 1m in the xy plane and 3m in the z axis was performed at the 0.30 g/t Au grade domain margins and at topography.
- The Aurizona resource estimates are supported by the following number of individual specific gravity measurements: Piaba – 12,657; Boa Esperança – 1273; Tatajuba – 804; Ferradura – 1000; Conceição – 473.
- The Piaba database contains 77,574 metres consisting of 351 diamond drill holes, 142 reverse circulation holes and 448 auger drill holes.
- The Boa Esperança database contains 9,015 metres consisting of 15 diamond drill holes, 48 reverse circulation holes 175 auger drill holes and 8 trenches.
- The Tatajuba database consists of 4,740 metres in 45 diamond drill holes (2008).
- The Ferradura database contains 5,398 metres consisting of 17 diamond drill holes, 13 reverse circulation holes 118 auger drill holes and 9 trenches.
- The Conceição database contains 2,834 metres consisting of 7 diamond drill holes, 10 reverse circulation holes 79 auger drill holes and 5 trenches.
- The following capping values were used prior to compositing: Piaba (Laterite – 11 g/t Au, Saprolite – 18 g/t Au, Transition/Fresh Rock – 25 g/t Au), Tatajuba – 10 g/t Au, Boa Esperança – 6 g/t Au, Ferradura – 10 g/t Au and Conceição – 3 g/t Au.
- Tonnes are rounded to the nearest 10,000. Ounces are rounded to the nearest 1,000 and small tonnage and grade differences may be found due to rounding.
- Mineral resources that are not mineral reserves do not have a demonstrated economic viability
- There may be political, environmental, legal and other risks that may materially affect the mineral resource estimate disclosed in this press release.
- The independent Qualified Person who prepared the preparation of the mineral resource estimate is Leah Mach, CPG, of the Denver office of SRK Consulting (U.S.), Inc.
This resource update was conducted by SRK Consulting (U.S.) Inc. performed according to Canadian National Instrument 43-101 guidelines, and based upon 14,411 metres of new diamond and reverse circulation by Luna. The updated Aurizona mineral resource estimate will form the basis for the updated reserve estimate for the Piaba deposit that is underway and due for completion during the first quarter of 2013. The Technical Report for the resource and reserve updates will be filed under Luna’s profile during April 2013 on SEDAR at www.sedar.com.
Except as otherwise indicated herein, Titus Haggan Ph.D., EurGeol Certified Professional Geologist #746, Luna’s Vice President Exploration is the Qualified Person as defined under National Instrument 43-101 who reviewed and approved the technical information in this press release. Mr. Haggan is responsible for the scientific and technical work on our exploration programs.
