Silver Wheaton reports over 1 billion ounces of attributable silver equivalent reserves17:01 EDT Tuesday, March 19, 2013TSX: SLWNYSE: SLWVANCOUVER, March 19, 2013 /CNW/ - Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX:SLW) (NYSE:SLW) is pleased to announcethat attributable proven and probable reserves increased by over 38% in 20121 to a record total of 1,116.1 million silver equivalent ounces2, consisting of 851.4 million ounces of silver and 4.96 million ounces of gold. Over the same period, attributable measured and indicated resources increased 28% to a record total of 603.2 million silver equivalent ounces, consisting of 529.1 million ounces of silver and 1.39 million ounces of gold. Attributable inferred resources totaled 341.4 million silver equivalent ounces, consisting of 294.7 million ounces of silver and 0.88 million ounces of gold.Silver Wheaton's increase in attributable reserves was a result of both acquisition and organic growth, which, when combined, more than offset depletion resulting from strong production over the year. In 2012, the Company acquired from Hudbay Minerals Inc. ("Hudbay") a precious metals stream from its 777 mine and a silver stream from its Constancia project.  Subsequent to 2012 year end, Silver Wheaton also acquired 25% of the gold from Vale S.A.'s ("Vale") Salobo mine for the life of mine and 70% of the gold from certain of its Sudbury operations for a 20-year period, with both these agreements effective as of January 1, 2013. In addition to these acquisitions, there was a substantial increase in reserves and resources at Augusta Resource Corp's ("Augusta") Rosemont mine based on an updated feasibility study released on July 24, 2012."Silver Wheaton has now reached yet another milestone with silver equivalent reserves exceeding well over one billion ounces," said Randy Smallwood, Silver Wheaton's President and Chief Executive Officer. "Silver equivalent reserves have grown by over 38% since the end of 2011 through both acquisition and organic growth, even after another year of strong production. On the acquisition front, we were able to add two new partners over the past year, which resulted in a significant increase to our gold reserves and resources. We now have almost five million ounces of gold reserves, over twenty times more than we had at the end of 2011. On the organic front, we saw substantial replacement of mined reserves in 2012 through our partners' exploration success. This once again highlights the strength of our partners and the high-quality, long-term nature of the mines underlying our streams.""We are extremely pleased with the reserve and resource growth we have seen over the past year, and we continue to be excited about the prospect of adding additional high-quality ounces to our portfolio in 2013 given the strength and depth of the current opportunity pipeline.  The foundation of any strong mining company is the quality of its mineral reserves and resources, and Silver Wheaton has one of the strongest and most active portfolios in the entire precious metals sphere."---------------------------------------------------1 Includes reserves and resources from Vale's Sudbury and Salobo mines which were added subsequent to year end 2012 but which had production attributed to Silver Wheaton as of January 1, 2013.2 Silver equivalent reserves and resources assumes a gold/silver ratio of 53.3:1.Salobo 43-101 Technical Report FiledSilver Wheaton has filed a National Instrument 43-101 ("NI 43-101") compliant technical report in support of the Company's February 5, 2013, news release which included a reserve and resource estimate at Vale's Salobo Mine located in Brazil. The independent technical report, entitled "Silver Wheaton Corp. Technical Report on the Mineral Reserves and Mineral Resources of the Salobo Copper-Gold Mine, Carajas, Pará State,Brazil" (the "Technical Report") and dated March 19, 2013, was prepared by Micon International Ltd. and authored by Jason Ché Osmond, C.Geol, FGS, EurGeol, Barnard Foo, P.Eng., James Turner, CEng, MIMMM, and Christopher Jacobs, CEng MIMMM, all Qualified Persons as defined by NI 43-101, and independent of Silver Wheaton for the purposes of NI 43-101 requirements. The Technical Report is available on SEDAR at and on the Company's website at Technical Report details the December 31, 2012 resources and reserves for Salobo whereas the Company's February 5, 2013, press release detailed the December 31, 2011 resources and reserves. The 2011 Salobo resources and reserves were entirely contained within a reserve pit and did not include measured and indicated resources.  Attributable proven and probable reserves are now estimated at 3.40 million ounces of gold versus 3.80 million ounces of gold as reported at year end 2011 (February 5, 2013 press release), due to changed estimation parameters in the block model and material mined during 2012. Attributable measured and indicated resources exclusive of reserves are now 0.77 million ounces of gold. Attributable inferred resources are now 0.37 million ounces of gold versus 0.13 million ounces of gold as originally reported.The tables below set forth the estimated mineral reserves and mineral resources for the mines relating to which the Company has purchase agreements, adjusted where applicable to reflect the Company's percentage entitlement to silver and/or gold produced from such mines, as of December 31, 2012, unless otherwise noted. The tables are based on information available to the Company as of the date of this press release.  The most current Mineral Reserves and Mineral Resources will be available on the Company's website.ATTRIBUTABLE PROVEN AND PROBABLE RESERVES (1,2,3,8,15,16)AS OF DECEMBER 31, 2012 UNLESS OTHERWISE NOTED (6)           As of December 31, 2012 unless otherwise noted(6)ProvenProbableProven &

Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources: The information contained herein uses the terms "Measured", "Indicated" and "Inferred" Mineral Resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them and expressly prohibits U.S. registered companies from including such terms in their filings with the SEC. "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 other economic studies. United States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves or that any exploration potential will ever be converted to any category of Mineral Reserves or Mineral Resources. United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable.  United States investors are urged to consider closely the disclosure in Silver Wheaton's Form 40-F, a copy of which may be obtained from Silver Wheaton or from Neil Burns, Vice President of Technical Services, is a "qualified person" as such term is defined under National Instrument 43-101, and has reviewed and approved the contents of this news release.About Silver WheatonSilver Wheaton is the largest precious metals streaming company in the world. Based upon its current agreements, forecast 2013 attributable production is approximately 33.5 million silver equivalent ounces3, including 145 thousand ounces of gold. By 2017, annual attributable production is anticipated to increase significantly to approximately 53 million silver equivalent ounces3, including 180 thousand ounces of gold. This growth is driven by the Company's portfolio of low-cost and long-life assets, including silver and precious metal streams on Barrick's Pascua-Lama project, Hudbay's Constancia project, and Vale's Salobo and Sudbury mines.CAUTIONARY NOTE REGARDING FORWARD LOOKING-STATEMENTSThe information contained herein contains "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian securities legislation.
