Exhibit 99.1

SILVER WHEATON ACQUIRES ADDITIONAL GOLD STREAM

FROM VALE’S SALOBO MINE

Vancouver, British Columbia — Silver Wheaton Corp. (“Silver Wheaton” or the “Company”) (TSX:SLW) (NYSE:SLW) is pleased to announce that its wholly-owned subsidiary, Silver Wheaton (Caymans) Ltd. (“Silver Wheaton Caymans”), has agreed to acquire from a subsidiary of Vale S.A. (“Vale”) (NYSE:VALE) an amount of gold equal to 25% of the life of mine gold production from its Salobo mine, located in Brazil. This acquisition is in addition to the 25% of the Salobo gold production that Silver Wheaton acquired in 2013. The Company will pay Vale cash consideration of US$900 million for the increased gold stream. In addition, Silver Wheaton will make ongoing payments of the lesser of US$400 (subject to a 1% annual inflation adjustment commencing in 2017) and the prevailing market price for each ounce of gold delivered under the agreement. The original gold purchase agreement, dated February 28, 2013, has been amended to provide for the additional 25% stream.

TRANSACTION HIGHLIGHTS

·                  Provides immediate production and cash flow

·                  Silver Wheaton will receive an additional 25% of the gold production from Vale’s Salobo mine, entitling the Company to a total of 50% of the life-of-mine gold production from the mine.

·                  This immediately increases Silver Wheaton’s production and cash flow profile by adding expected average gold production of 70,000 ounces per year for the first 10 years and 60,000 ounces per year over the first 30 years (5.0 million and 4.3 million silver equivalent ounces1, respectively).

·                  Significant expansion and exploration potential exists at Salobo, which currently has an extensive reserve base and good depth potential.

·                  Subsequent to the closing of this acquisition, Silver Wheaton’s estimated Proven and Probable gold reserves increase by 3.3 million ounces, Measured and Indicated gold resources increase by 0.8 million ounces, and Inferred gold resources increase by 0.4 million ounces.

·                  Over the next five years, gold as a percentage of Silver Wheaton’s forecasted production is estimated to grow to over 40%.

1   Silver equivalent production forecast assumes a gold/silver ratio of 72:1

·                  Increases Silver Wheaton’s growth profile

·                  Silver Wheaton is also pleased to announce its updated production guidance, which includes the additional stream from Salobo. In 2015, Silver Wheaton forecasts 43.5 million ounces of silver equivalent production1 (including 230,000 ounces of gold) growing to 51 million ounces of silver equivalent production1 (including 325,000 ounces of gold) in 2019.

“The Salobo mine is one of Silver Wheaton’s cornerstone assets and we are fortunate to have the opportunity to double our gold production from this high-quality mine,” said Randy Smallwood, Silver Wheaton’s President and Chief Executive Officer. “Since we founded our company ten years ago, we have had a clear vision of the characteristics of our ideal asset. To start, the asset is managed by a strong operating partner and is located in a low political-risk jurisdiction. Furthermore, it is primarily a base metal producer where precious metals represent only a relatively small portion of the mine’s overall economics. Vale’s Salobo mine possesses all of these characteristics, while also offering over 40 years of defined mine life as well as the potential for significant exploration and expansion upside. Salobo is certainly one of the best assets we have ever seen and one that readily lends itself to streaming.”

“With over 70% of global silver production sourced as by-product, we continue to believe that the silver market represents the largest market for streaming opportunities. However, Silver Wheaton has never been averse to strategically layering additional gold into the streaming mix when the right opportunity presents itself.”

TRANSACTION TERMS

Silver Wheaton Caymans has agreed to acquire from a subsidiary of Vale an additional 25% of the life of mine gold production from Vale’s Salobo mine. Production will accrue retroactively to Silver Wheaton Caymans as of January 1, 2015.

Silver Wheaton Caymans will pay Vale cash consideration of US$900 million for the increased gold stream. In addition, Silver Wheaton Caymans will make ongoing payments of the lesser of US$400 (subject to a 1% annual inflation adjustment commencing in 2017 for the Salobo stream) and the prevailing market price, for each ounce of gold delivered under the agreement. The terms of the existing gold stream on Salobo were modified so that the annual inflation adjustment that was scheduled to start in 2016 will now start coincident with this stream in 2017.

Vale is in the process of ramping up mill throughput at the Salobo mine to 24 million tonnes per annum (“Mtpa”). If throughput capacity is expanded within a predetermined period, Silver Wheaton Caymans will be required to make an additional payment to Vale, relative to the 50% stream, based on a set fee schedule that now ranges from US$88 million if throughput is expanded beyond 28 Mtpa by January 1, 2036, up to US$720 million if throughput is expanded beyond 40 Mtpa by January 1, 2018.

FINANCING THE ACQUISITION

To pay the initial upfront cash payment of US$900 million, Silver Wheaton intends to use cash on hand together with the net proceeds of an equity offering announced concurrently as of today’s date (the “Offering”). Silver Wheaton may also use amounts borrowed under its existing revolving credit facility.

ABOUT THE SALOBO MINE

According to Vale’s public filings, the Salobo mine, located in the Pará state of Brazil, is the largest copper deposit in Brazil. This low-cost copper-gold mine was commissioned in November 2012 with a design throughput capacity of 12 Mtpa and subsequently expanded to 24 Mtpa of mill capacity in mid-2014. The mine is well-positioned relative to infrastructure and is connected to the national power grid.

The Salobo mine has total estimated Mineral Reserves of 1.179 billion tonnes grading 0.35 g/t gold1, and, along with additional Mineral Resources, also has substantial exploration and expansion potential. The acquisition of an additional 25% life of mine gold stream adds an estimated 3.3 million ounces of Proven and Probable Mineral Reserves, 0.8 million ounces of Measured and Indicated Mineral Resources, and 0.4 million ounces of Inferred Mineral Resources attributable to Silver Wheaton. Total estimated attributable Mineral Reserves and Mineral Resources for the now 50% life of mine gold stream are detailed in the table below.

SILVER WHEATON ANNOUNCES NEW PRODUCTION GUIDANCE

Silver Wheaton is pleased to provide its updated one and five-year production guidance, which incorporates the additional 25% life of mine gold stream on the Salobo mine. In 2015, Silver Wheaton’s estimated attributable silver equivalent production is forecast to be 43.5 million silver equivalent ounces2, including 230,000 ounces of gold. In 2019, estimated annual attributable production is anticipated to increase over 40% compared to 2014 levels, growing to approximately 51 million silver equivalent ounces2, including 325,000 ounces of gold.

The additional ounces from Salobo to our production profile as well as the ramp-up of Hudbay Minerals Inc.’s (“Hudbay”) Constancia mine in 2015 more than offset the anticipated reduction in attributable production from other assets in Silver Wheaton’s current streaming portfolio. Hudbay’s Constancia mine is expected to meet the completion test well before 2016, resulting in gold production from the 777 mine attributable to Silver Wheaton dropping from 100% to 50% in 2017. In addition, the 10-year term contract on Capstone Mining’s Cozamin mine, acquired with Silver Wheaton’s 2009 acquisition of Silverstone, expires in April 2017. Finally, as Hudbay provides no formal production guidance for its Rosemont project, Silver Wheaton no longer includes any production from the Rosemont project in its production forecast for

The Company reports silver equivalent sales volume for the year ended December 31, 2014, was 32.9 million ounces, compared to 30.0 million ounces in 2013, representing an increase of 9.8%.

SILVER WHEATON ANNOUNCES UPDATED RESERVES AND RESOURCES

As of December 31, 2014, and detailed in the tables at the end of this news release, Proven and Probable Mineral Reserves attributable to Silver Wheaton were 757.7 million ounces of silver compared to 781.3 million ounces reported by the Company in its management’s discussion and analysis for the quarter ended September 30, 2014, a decrease of 3%, and 9.27 million ounces of gold compared to 6.09 million ounces, an increase of 52%. On an attributable Measured and Indicated basis, silver resources were 549.5 million ounces compared to 569.4 million ounces reported by the Company in its management’s discussion and analysis for the quarter ended September 30, 2014, a decrease of 3%, and gold resources were 2.76 million ounces compared to 1.92 million ounces, an increase of 43%. On an attributable Inferred Resource basis, silver resources were 275.2 million ounces compared to 298.7 million reported by the Company in its management’s discussion and analysis for the quarter ended September 30, 2014, a decrease of 8%, and gold resources were 1.46 million ounces compared to 1.03 million ounces, an increase of 41%.

The tables at the end of this news release set forth the estimated mineral reserves and mineral resources (silver and/or gold only) for the 27 mining assets which are subject to the Company’s precious metal purchase agreements, adjusted where applicable to reflect the Company’s percentage entitlement to silver and/or gold produced from such assets, as of December 31, 2014, unless otherwise noted. The tables are based on information available to the Company as of the date of this news release, and therefore will not reflect updates, if any, after such date.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES: The information contained herein has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws.  The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 — Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). These definitions differ from the definitions in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”). Under U.S. standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.  Also, under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence and as to their economic and legal feasibility.  It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable.  Mineral resources that are not mineral reserves do not have demonstrated economic viability. 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. Accordingly, information contained herein that describes the Corporation’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.  United States investors are urged to consider closely the disclosure in the U.S. prospectus, a copy of which is available at www.sec.gov.
