Vancouver, British Columbia | October 27, 2015

Sandstorm Gold Ltd. ('Sandstorm' or the 'Company') (NYSE MKT: SAND, TSX: SSL) has entered into three agreements with Yamana Gold Inc. ('Yamana') (NYSE: AUY, TSX: YRI) that include production streams from up to five of Yamana's projects. For upfront consideration of US$148 million in cash, US$4 million in cash payable in six months and 15 million warrants of the Company, Sandstorm will receive a silver stream on the Cerro Moro development project in Argentina ('Cerro Moro') that includes interim silver deliveries during years 2016 to 2018 from currently operating mines, a copper stream on the operating Chapada mine in Brazil ('Chapada') and a potential gold stream on the Agua Rica project in Argentina ('Early Deposit Gold Stream'). The Sandstorm warrants issued to Yamana have a strike price of US$3.50, a term of 5 years and are exercisable upon achievement of specific milestones with respect to the construction of Cerro Moro (the 'Transaction').

TRANSACTION HIGHLIGHTS

• Imminent Cash Flow: New silver and copper streams expected to contribute US$10 million of cash flow annually starting in 2016, increasing to US$20 million annually by 2019 representing a 55% increase in the Company's 2019 cash flow;
• Asset Diversification: Multi-asset silver stream that includes production from Chapada, Minera Florida and Cerro Moro, a copper stream on Chapada, and an Early Deposit Gold Stream on Agua Rica;
• Downside Protection: 24-month silver stream backstop from the El Peñon mine if Cerro Moro does not reach production by 2019;
• Asset Quality: The projects underlying the Transaction are low cost, economically robust assets with significant exploration upside;
• Improved Counterparty Profile: 90% of Sandstorm's cash flow to come from majors, mid-tiers and debt-free junior mining companies by 2019;
• Precious Metal Focus: Precious metals and diamonds to make up approximately 83% of the Company's cash flow by 2019.

MULTI-ASSET SILVER STREAM

Silver Stream Terms

In exchange for US$70 million, Sandstorm has agreed to purchase an amount of silver based on production from the Cerro Moro mine (the 'Silver Stream') equal to:

• 20% of the silver produced, up to a maximum of 1.2 million ounces of silver annually, until Yamana has delivered 7.0 million ounces of silver to Sandstorm; then
• 9.0% of the silver produced thereafter, for the life of the mine.

Sandstorm has also agreed to purchase an amount of silver from Yamana's Minera Florida mine in Chile and Chapada mine in Brazil, during the years 2016 through 2018 equal to:

• 38% of the silver produced, up to a maximum of 200,000 ounces of silver annually from Minera Florida; and
• 52% of the silver produced, up to a maximum of 100,000 ounces of silver annually from Chapada.

Sandstorm will make ongoing payments for each ounce of silver received, equal to 30% of the spot price per ounce of silver.

Downside Protection

If by January 1, 2019, the Cerro Moro processing facility has not averaged 80% of its daily nameplate production capacity over a 30-day period (the 'Commencement of Production'), then Yamana's producing El Peñon mine in Chile ('El Peñon') will provide a 24 month backstop until the Commencement of Production is satisfied. During the 24 month backstop, if applicable, Sandstorm will purchase an amount of silver equal to 16% of El Peñon's silver production up to a maximum of 1.2 million ounces per annum, which is expected to generate US$13 million of cash flow per year to the Company.

If Cerro Moro has not achieved the Commencement of Production and Sandstorm has not received cumulative pre-tax cash flow equal to US$70 million from the Silver Stream, then the First Chapada Delivery Threshold and the Second Chapada Delivery Threshold (as defined below) will cease to be in effect and Sandstorm will continue to purchase 4.2% of Chapada's payable copper production, up to a maximum of 3.9 million pounds of copper annually, until such time as Sandstorm has received cumulative pre-tax cash flow equal to US$70 million, or Cerro Moro has achieved the Commencement of Production.

The Silver Stream on Cerro Moro is based on production from the project and was structured between Sandstorm's Canadian parent company and a Yamana entity outside of Argentina and therefore, the Company does not anticipate being subject to tax risk or currency risk outside of Canada.

About the Cerro Moro Project

The Cerro Moro project is located approximately 70 kilometres southwest of the coastal port city of Puerto Deseado in the Santa Cruz province of Argentina. Cerro Moro contains a number of high grade epithermal gold and silver deposits, some of which will be mined via open pit and some via underground mining methods. In February 2015, Yamana announced that it would proceed with the construction of Cerro Moro. The current plan indicates average annual production in the first three years of 135,000 ounces of gold and 6.7 million ounces of silver, with the life of mine annual production averaging approximately 102,000 ounces of gold and 5 million ounces of silver at a throughput of 1,000 tonnes per day. The concentrator will consist of a standard crushing, grinding and flotation circuit with a counter current decantation and a Merrill Crowe circuit included.

According to Yamana, the procurement of long lead items is underway and Cerro Moro remains on track for construction to begin in early 2016, commencing with select bulk earthworks activities. Project capital costs, as estimated in Q1 2015, are approximately US$265 million which includes US$31 million in late 2015 for detailed engineering and pre-development.

CHAPADA COPPER STREAM

Copper Stream Terms

In exchange for US$70 million, Sandstorm has agreed to purchase an amount of copper based on production from the Chapada mine (the 'Copper Stream') equal to:

• 4.2% of the copper produced, up to a maximum of 3.9 million pounds of copper annually, until Yamana has delivered 39 million pounds of copper to Sandstorm (the 'First Chapada Delivery Threshold'); then
• 3.0% of the copper produced until, on a cumulative basis, Yamana has delivered 50 million pounds of copper to Sandstorm (the 'Second Chapada Delivery Threshold'); then
• 1.5% of the copper produced thereafter, for the life of the mine.

Sandstorm will make ongoing payments for each pound of copper received equal to 30% of the spot price per pound of copper.

About the Chapada Project

Chapada is an open pit gold-copper mine located 270 kilometres northwest of Brasília in Goiás state, Brazil and has been in production since 2007. The ore is treated through a flotation plant with capacity of 22 million tonnes per annum. The Chapada operations have a mine life of over 20 years based on the most recent Proven and Probable Reserves and the mine is projected to produce 120,000 ounces of gold, 120 million pounds of copper and 305,000 ounces of silver during the 2015 year.

Yamana has benefitted from significant discoveries at Chapada in the past and expects to complete 10,000 metres of exploration drilling and 12,000 metres of infill drilling over the course of 2015. The drill campaign has identified a 1.5 kilometre strike length of mineralization which remains open to the southwest and to depth. Exploration will continue to test both the strike and down dip extensions of the mineral body. The infill drilling programs are focused on upgrading mineral resources.

EARLY DEPOSIT GOLD STREAM

Early Deposit Gold Stream Terms

In exchange for a US$12 million payment, US$4 million of which is payable in six months (the 'Advance Payment'), Sandstorm has entered into an Early Deposit Gold Stream agreement on the Agua Rica project, a large 1,400 million tonne, copper-molybdenum-gold porphyry deposit. At the time when 25% of the construction of Agua Rica has been completed, Sandstorm may elect to make an additional advance payment in an amount between US$135 million and US$225 million based on the following formula: US$150,000 multiplied by the price of gold plus US$7.5 million (the 'Additional Advance Payment'). If Sandstorm elects to pay the Additional Advance Payment, the Company will have the right to purchase an amount of gold equal to 20% of the life of mine gold produced from Agua Rica. Sandstorm would make ongoing payments for each ounce of gold received, equal to 30% of the spot price per ounce of gold.

If Sandstorm elects not to pay the Additional Advance Payment, the Advance Payment will convert into a 0.25% net smelter returns royalty on Agua Rica and all other rights under the Early Deposit Gold Stream agreement will terminate. In addition, in the event that Sandstorm wishes to syndicate the gold stream to a third party, it has the right to transfer any and all of its rights and obligations, under certain conditions.

About the Agua Rica Project

Agua Rica is a porphyry copper, molybdenum, gold and silver deposit located in the province of Catamarca, Argentina. In March 2015, Yamana signed a Definitive Agreement with the provincial Government of Catamarca, Argentina, represented by the provincial mining company Catamarca Mineria y Energetica Sociedad del Estado ('CAMYEN'). The agreement advances the Memorandum of Understanding between CAMYEN and Yamana, which set the groundwork for cooperation to consolidate important mining projects and prospective properties in the province, creating the Catamarca mining district.

CAUTIONARY NOTE TO U.S. INVESTORS

Canadian standards, including Canadian National Instrument 43-101, differ significantly from the requirements of the SEC, and Mineral Reserve and Mineral Resource information included in this press release may not be comparable to similar information disclosed by U.S. companies. In particular, the term 'resource' does not equate to the term 'reserve'. Accordingly, Mineral Reserve and Mineral Resource estimates included in this press release may not qualify as 'reserves' under SEC standards. The SEC's disclosure standards normally do not permit the inclusion of information concerning 'Measured Mineral Resources', 'Indicated Mineral Resources' or 'Inferred Mineral Resources' or other descriptions of the amount of mineralization in mineral deposits that do not constitute 'reserves' by U.S. standards in documents filed with the SEC.

U.S. investors should also understand that 'Inferred Mineral Resources' have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. Investors are cautioned not to assume that all or any part of an 'Inferred Mineral Resource' exists or is economically or legally mineable. Disclosure of 'contained ounces' in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute 'reserves' by SEC standards as in-place tonnage and grade without reference to unit measures. In addition, the definitions of 'Proven Mineral Reserves' and 'Probable Mineral Reserves' under reporting standards in Canada differ in certain respects from the standards of the SEC. . U.S. Investors are urged to consider closely the disclosure in our Form 40-F which may be obtained from our website or the SEC website at http://www.sec.gov/edgar.shtml.
