VANCOUVER, BRITISH COLUMBIA--(Marketwire - 01/06/11) - Sandstorm Resources Ltd. ("Sandstorm" or the "Company") (TSX-V:SSL - News) announces the results from a recently completed independent Technical Report (the "Report") from Sandstorm's partner company Brigus Gold Corp. ("Brigus") (TSX:BRD - News) and its Black Fox Mine (the "Black Fox Mine") in the Timmins Gold District, Ontario, Canada. In accordance with Sandstorm's gold purchase agreement with Brigus, Sandstorm is entitled to purchase 12% of the life of mine gold produced from the Black Fox Mine at a per ounce price equal to the lesser of US$500 and the then prevailing market price. The Report was based on the mine operations and reserves as of October 31, 2010 and was prepared in compliance with Canadian National Instrument 43-101 ("NI 43-101") by Wardrop Engineering Inc., a Tetra Tech Company, with assistance from the Brigus staff. All currency is reported in US dollars.
Highlights from the Black Fox Report include:
-- Mine life of 8.6 years based on existing reserves.
-- Processing rate of 730,000 tonnes per annum (2,000 tonnes per day
("tpd")) and a recovery rate of 94%.
-- Average cash operating costs of $502 per ounce ($66.94 per tonne milled)
-- Average annual production of 104,000 ounces of gold over the next five
years of production.
Potential upside exists beyond the results of the Report as it excludes anticipated extensions to the Black Fox ore body that remain open at depth and along strike.
Estimated Mineral Resources
As of October 31, 2010, Indicated Resources at Black Fox, including reserves, were estimated at 1,031,400 ounces of gold within 5.7 million tonnes of ore at an average gold grade of 5.7 grams per tonne ("g/t"). Additional Inferred Resources were estimated at 77,500 ounces of gold within 0.8 million tonnes of ore at 3.1 g/t. Follow up and infill drilling around these drill holes provides Brigus with high-priority exploration targets and a further opportunity for future resource additions. The gold mineral resource statement in the Report was reported at a 0.88 g/t cut-off grade for the open pit and at a 2.54 g/t cut-off grade for the underground.
The resource estimate as of October 31, 2010 shows Indicated Resources, including Probable Reserves and Inferred Resources as follows:

Estimated Mineral Reserves
According to the Report, Black Fox's estimated gold mineral reserves total 0.9 million ounces of gold within 6.4 million tonnes at an average gold grade of 4.4 g/t. The economic analysis in the Report was based on the following gold mineral reserve estimate as of October 31, 2010:

Footnotes to Tables 1 and 2:
1. Indicated Resources include Probable Reserves.
2. Metal prices used for initial cut-off calculations are $1,150 per oz for
88% of the gold sold and $500 per oz for gold sold through the gold
purchase agreement.
3. The estimated underground reserves include 10% unplanned dilution at 0
g/t grade from the backfill and 15% planned dilution at 1 g/t from the
walls for a total of 25% dilution. The estimated open pit reserves
include 30% dilution at 0 g/t and a 95% mining recovery factor for both.
The higher average gold grades for the open pit and underground in the
Indicated Resources compared to the Probable Reserves are the result of
no dilution being applied to Indicated Resources.
4. The estimated mineral resources are not mineral reserves and do not have
demonstrated economic viability.
5. Numbers may not sum as they have been rounded in all categories to
reflect the precision of the estimates.
6. The mineral resources were estimated using the ordinary kriging method.
7. The mineral reserves were estimated from the life of mine plan, which
defined sustaining capital requirements and mine operating costs, to
demonstrate that these reserves can be economically extracted and
processed. Mining losses and dilution were determined based on sub-
surface geotechnical conditions, the mining method employed and
equipment capabilities for each area of the mine.
8. Contained metal in estimated reserves remains subject to metallurgical
recovery losses.
A summary of the economic results for the base case are as follows:

Upside Opportunities
Brigus believes that there is significant upside opportunity for additions to reserves and resources from its ongoing exploration drilling program within the 42 square kilometre Black Fox Complex including potential extensions to the Black Fox ore body.
The Report identifies the following upside operating opportunities:
-- Potential expansion and further optimization of the mill to enhance the
gold recovery rate by expanding, or optimizing, the grinding and
leaching circuit.
-- The deposit exhibits good potential for additional resources at depth
and along strike.
-- Cut and fill stopes have been conservatively designed and in wider areas
will support higher productivity and lower unit costs.
-- Evaluation of long hole stoping methods for steeply dipping ore blocks
to enhance underground mining productivity and lower mining costs.
-- Toll processing of lower grade, open pit ore stockpiles.
Black Fox Operation Update
Following the mid-2010 merger of Linear Gold Corp. and Apollo Gold Corporation, Brigus has optimized mining operations in the open pit while simultaneously initiating underground mine development at Black Fox. To date, ongoing development of the new underground infrastructure has been slower than anticipated. Completion of the new vent raise and portal are now targeted for completion by mid-February 2011. Construction and relocation of the vent raise and portal continue to result in logistical issues that have significantly restricted ore production from the open pit. During this transitional period the Black Fox Mill has continued to operate at 2,000 tpd by drawing down low-grade stockpiles (less than 2.0 g/t) held in inventory. During the fourth quarter of 2010, Brigus produced approximately 13,700 ounces of gold from approximately 184,000 tonnes of ore.
Brigus is committed to the completion of the underground development and near-term commencement of commercial production levels. The new vent raise and portal is nearing completion and when complete will result in the attainment of commercial production during the first quarter of 2011 and quarterly production increases over the balance of the year. The 2011 mine plan is being adjusted to reflect the updated schedule and revised guidance will be provided following completion of the portal and vent raise.
