Cautionary Statements

CAUTIONARY NOTE REGARDING FORWARD LOOKING-STATEMENTS

This presentation contains “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation. Forward-looking statements include, but are not limited to, statements with respect to the future price of silver, the estimation of mineral reserves and resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, reserve determination and reserve conversion rates. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”

  • r “does not anticipate”, or “believes”, or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be

achieved”. Assumptions upon which such forward looking statements are based include that Silver Wheaton and Silverstone will be able to satisfy the conditions in the definitive agreement, that the due diligence investigations of each party will not identify any materially adverse facts or circumstances, that the required approvals will be obtained from the shareholders of each of Silver Wheaton and Silverstone, that all third party regulatory and governmental approvals to the transactions will be obtained and all other conditions to completion of the transaction will be satisfied or waived. Many of these assumptions are based on factors and events that are not within the control of Silver Wheaton and Silverstone and there is no assurance they will prove to be correct. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of Silver Wheaton and Silverstone to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: risks related to the integration of acquisitions, the absence of control over mining operations from which Silver Wheaton and Silverstone purchase silver and gold and risks related to these mining operations, including risks related to international operations, actual results of current exploration activities, actual results of current reclamation activities, conclusions of economic evaluations, changes in project parameters as plans continue to be refined, as well as those factors discussed in the section entitled “Description of the Business – Risk Factors” in Silver Wheaton’s annual information form for the year ended December 31, 2007 incorporated by reference into Silver Wheaton’s Form 40-F on file with the U.S. Securities and Exchange Commission in Washington, D.C. and although Silver Wheaton and Silverstone have attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Silver Wheaton and Silverstone do not undertake to update any forward-looking statements that are incorporated by reference herein, except in accordance with applicable securities laws.

CAUTIONARY NOTE TO U.S. INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES

This presentation uses the terms “Measured”, “Indicated” and “Inferred” Resources. U.S. 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. “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. U.S. investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves. U.S. investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable. Full details on Silver Wheaton reserves and resources for Luismin, Zinkgruvan, Yauliyacu, Peñasquito, Stratoni, Mineral Park, Campo Morado, La Negra, and Keno Hill can be found on the Company website at www.silverwheaton.com.

Mineral Park Reserves - 0.237% Cu equivalent cut off grade (hypogene), 0.283% Cu equivalent cut off grade (supergene), silver was not included. 7.

The San Pedrito project Resources at San Martin– US$5.50 per ounce c. Zinkgruvan Resources – US$10.00 per ounce d. Stratoni Resources – US$12.00 per ounce e.

Silver Wheaton’s purchase agreement with Glencore provides for the delivery of up to 4.75 million ounces of silver per year for 20 years so long as production allows. In the event that silver produced at Yauliyacu in any year totals less than 4.75 million ounces, the amount sold to Silver Wheaton in subsequent years will be increased to make up the shortfall. 9. Peñasquito, Campo Morado and La Negra reserves and resources reported represent the share attributable to Silver Wheaton. 10. The Mineral Park Reserves do not include the Leach material. 11. Silver is produced as a by-product metal at all operations, therefore the economic cut off applied to the reporting of silver reserves and resources will be influenced by changes in the commodity prices of other metals at the time. 12. The Company considers the San Dimas, Yauliyacu and Peñasquito operations to be Material Assets, and has technical reports filed and available on www.sedar.com on each of these assets. 13. Los Filos reserves and resources are reported without the Bermejal deposit, as Bermejal is not subject to the silver sales agreement.

GFMS Silver Price Outlook - Conclusion

72

  • Silver’s supply/demand fundamentals (excluding investment) turning

negative in 2009 due mainly to lower fabrication demand, though supply side less threatening than formerly expected

  • Silver market will therefore move back into surplus but this metal will

be absorbed by investors

  • Silver prices will be volatile but tend to increase from current levels
  • GFMS under its base case scenario currently forecast a calendar

2009 average silver price of around $13/oz
