For further information on Mineral Reserves and Mineral Resources and on Silver Wheaton more generally, readers should refer to Silver Wheaton's Annual Information Form for the year ended December 31, 2011, and other continuous disclosure documents filed by Silver Wheaton since January 1, 2012, available on SEDAR at http://www.sedar.com. Silver Wheaton's Mineral Reserves and Mineral Resources are subject to the qualifications and notes set forth therein. 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 http://www.sec.gov/edgar.shtml. _____________________________ [ 1] Silver equivalent production forecast assumes a gold/silver ratio of 53.3:1.
