Silver Wheaton Reports Record Attributable Reserves and Resources in 2009
VANCOUVER, Canada, March 1, 2010 /PRNewswire-FirstCall/ --
TSX: SLW
NYSE: SLW
Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX, NYSE:SLW) is pleased to announce that attributable proven and probable reserves more than doubled in 2009, including an increase of 431 million ounces of silver and 220,000 ounces of gold, to a record 875 million silver equivalent ounces(1). Over the same period, attributable measured and indicated resources increased by 72%, including an increase of 141 million ounces of silver and 180,000 ounces of gold, to a record 366 million silver equivalent ounces. Attributable inferred resources increased by 4%, including an increase of 12 million ounces of silver and 50,000 ounces of gold, to a record 408 million silver equivalent ounces.
Silver Wheaton's acquisition during the year of Silverstone Resources Corp., together with the Barrick silver stream agreement, by which it acquired 25% of the life of mine silver production from the Pascua-Lama project, as well as 100% of the silver production from the Veladero, Lagunas Norte and Pierina mines until the end of 2013, was responsible for a significant portion of the Company's total reserve growth in 2009. In addition, continued exploration success at the mines from which Silver Wheaton purchases its silver, led to organic reserve growth of approximately 5%.
The table below summarizes the growth in attributable silver reserves year over year. Year end reserve and resource updates for the Mineral Park, Campo Morado, Stratoni, Cozamin and La Negra mines are forthcoming and have not been included in this calculation.
Proven and Probable Silver Reserves as of December 31, 2008 429.7Moz
Net acquisitions during 2009 418.1Moz
Mined ounces during 2009 (includes silver lost to process) (19.5)Moz

Proven and Probable Silver Reserves as of Dec 31, 2009 860.8Moz
Proven and Probable Gold Reserves as of Dec 31, 2009 220Koz
---------
Total Proven and Probable Silver Eq. Reserves as of
Dec 31, 2009(1) 875.3Moz
Subsequent to the end of 2009, the Company acquired the life of mine silver and gold production from the Rosemont project located in Arizona, and converted a debenture to acquire 12.5% of the life of mine silver production from the Loma de La Plata zone of the Navidad project in Argentina, further increasing Silver Wheaton's reserve and resource base.
"We had another year of exceptional reserve growth, fueled by the Barrick and Silverstone acquisitions," said Peter Barnes, Chief Executive Officer of Silver Wheaton. "We are particularly proud that our record of increased silver reserves, on both an absolute and per share basis, has now been extended to five consecutive years. Such an achievement speaks to the high-quality of the mines underlying our silver purchase agreements, and to our track-record of completing accretive acquisitions creating significant long-term value. As 2010 progresses, we are confident that our partners will continue to build resources, while we focus on identifying additional high-quality silver stream opportunities."

i. Resources for La Negra are reported as of February 15, 2008 for the Alacran, March 14, 2008 for the Monica and December 31, 2009 for Maravillas.
7. Process recoveries are the average percentage of silver in a saleable product (dore or concentrate) recovered from mined ore at the applicable site process plants as reported by the operators.
8. Mineral Reserves are estimated using appropriate process recovery rates and commodity prices of US$13 per ounce of silver unless otherwise noted below:
a. San Martin - US$10.00 per ounce
b. Pascua-Lama, Lagunas Norte, Veladero and Pierina - US$14.00 per ounce
c. Yauliyacu - US$13.00 per ounce
d. Zinkgruvan -US$3.90 per ounce
e. Mineral Park - 0.237% Cu equivalent cut-off grade (hypogene), 0.283% Cu equivalent cut-off grade (supergene). Copper equivalent considers only copper and molybdenum values.
f. Minto - internal cut-offs of US$24.18 for Minto North, US$25.47 for Ridgetop and US$24.94 for Area 2/ 118 based on a NSR model generated using US$2.00 per pound Cu.
g. Aljustrel - 1.5% copper cut-off for all copper Reserves and the zinc cut-offs were 4.5%, 4.0% and 4.0% respectively for the Feitais, Moinho and Estacao zinc Reserves.
h. Neves-Corvo - 1.6% copper cut-off for the copper reserve and 4.6% zinc cut-off for the zinc Reserve.
i. Cozamin - US$4.00 per ounce
9. Mineral Resources are estimated using appropriate recovery rates and commodity prices of US$15 per ounce of silver, unless otherwise noted below:
a. San Martin (excluding San Pedrito) - US$10.00 per ounce; San Martin (San Pedrito only) - US$5.50 per ounce
b. Pascua-Lama, Lagunas Norte, Veladero, and Pierina - US$14.50 per ounce
c. Zinkgruvan - US$3.90 per ounce
d. Mineral Park - 0.225% Cu Equivalent cut-off grade. Copper equivalent considers only copper and molybdenum values.
e. Minto - 0.5% copper cut-off.
f. Aljustrel - 1.5% copper cut-off for all copper Resources and the zinc cut-offs were 4.5%, 4.0% and 4.0% respectively for the Feitais, Moinho and Estacao zinc Resources.
g. Campo Morado - 5.0% zinc only cut-off grade.
h. Neves-Corvo - 1.0% copper cut-off for copper Resource and 3.0% zinc cut-off for the zinc Resource.
i. Cozamin - 1.15% copper cut-off for San Roberto Area and 3.0% zinc cut-off for San Rafael Area.
j. Keno Hill - US$15.25 per ounce for the Southwest and 99 Zones and US$14.50 per ounce for the East Zone.
k. La Negra (Alacran) - US$12.00 per ounce; La Negra (Monica) - US $13.50 per ounce
10. Los Filos Resources and Reserves are reported without the Bermejal deposit, as Bermejal is not subject to the silver sales agreement.
11. The Company's attributable tonnage at Lagunas Norte was estimated by assuming 2008 production levels for four years. This tonnage was pro- rated between Proven and Probable Reserves according to the ratio of the December 31, 2009 Proven and Probable Reserves for Lagunas Norte as published by Barrick, applying average reserve grades.
12. The Company's attributable tonnage at Veladero is estimated based on a production rate of 85,000 tonnes per day for four years. This tonnage was pro-rated between Proven and Probable Reserves according to the ratio of the December 31, 2009 Proven and Probable Reserves for Veladero as published by Barrick, applying average reserve grades.
13. The Company'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 maximum amount to be sold to the Company in subsequent years will be increased to make up the shortfall.
14. The Mineral Park Resources and Reserves do not include the SX/EW leach material since this process does not recover silver.
15. A portion of the Proven Reserve at Minto consists of stockpiled material (779,000 tonnes) which has not been assayed for gold because the on-site laboratory does not have the ability. A gold grade of 0.67 g/t has been assumed for the stockpile based on a statistical analysis of grade trends during the period which it accumulated.
16. The Company has filed a technical report for each of San Dimas, Yauliyacu, Penasquito and Pascua-Lama on SEDAR.
17. Silver is produced as a by-product metal at all operations with the exception of the Keno Hill project; therefore, the economic cut-off applied to the reporting of silver Resources and Reserves will be influenced by changes in the commodity prices of other metals at the time.
18. Subsequent to the end of 2009, the Company (a) elected to convert the debenture with Pan American Silver Corp. into an agreement to purchase 12.5% of the life of mine payable silver from the Loma de la Plata zone, one of seven zones comprising the Navidad project; and (b) completed a precious metals purchase agreement with Augusta Resource Corporation whereby the Company acquired 100% of the life of mine payable silver and gold from the Rosemont Project in Arizona, U.S. Attributable reserves and resources from these projects are not included in the above reserve and resource statement.
CAUTIONARY LANGUAGE REGARDING RESERVES AND RESOURCES
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, 2008, and other continuous disclosure documents filed by Silver Wheaton since January 1, 2009, available on SEDAR at 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. 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. Mr. Randy V.J. Smallwood, P.Eng., President of Silver Wheaton, 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.
CAUTIONARY NOTE REGARDING FORWARD LOOKING-STATEMENTS
