    gold from the Hudbay 777 mine ($5.90 and $400 per ounce of silver and
    gold, respectively).
  *Declared quarterly dividend of $0.14 per common share, representing 20% of
    the cash generated by operating activities during the three months ended
    December 31, 2012.

2013 OUTLOOK

  *Silver Wheaton anticipates a 13% year over year increase in its 2013
    attributable production to approximately 33.5 million silver equivalent
    ounces, including 145 thousand ounces of gold.
  *In 2017, the Company forecasts 53 million ounces of silver equivalent
    production (including 180 thousand ounces of gold), which represents an
    increase of 79% from 2012.
  *The acquisition of the Salobo and Sudbury gold streams from Vale S.A.
    ("Vale") subsequent to December 31, 2012, is expected to double Silver
    Wheaton's attributable gold production over the next five years. Coupled
    with a full year of attributable production from Hudbay's 777 mine,
    acquired in August 2012, these cornerstone assets will drive the company's
    production growth in 2013.
  *As per the Company's news release dated March 19, 2013, attributable
    silver and gold reserves increased to 851.4 million ounces and 4.96
    million ounces, respectively, as a result of organic and acquisition
    growth, inclusive of the acquisition of gold streams from Vale's Salobo
    and Sudbury mines. Based on reserve estimates as at December 31, 2012 ^[
    ^1] , following the Vale transaction, silver equivalent reserves
    attributable to Silver Wheaton have grown to 1.12 billion ounces ^[ ^2] .

___________________________

^[1] Please refer to non-IFRS measures at the end of this press release.

[ ^2] Silver equivalent reserves and resources assume a gold/silver ratio of
53.3:1.

"2012 was another exceptional year for Silver Wheaton, anchored by a fourth
quarter that saw record production, sales, revenue, net income, and cash flow
for the company," said Randy Smallwood, President and Chief Executive Officer
of Silver Wheaton. "With the addition of production from Hudbay's 777 mine
midway through the year, plus growing production from Peñasquito, San Dimas
and Zinkgruvan, 2012 production exceeded our forecast by over one and a half
million ounces."

"This translated into sales of over 27 million ounces, with the fourth quarter
coming in at over nine million ounces, and full year cash flows of over $719
million. Given our dividend policy of paying out 20% of the trailing quarter's
cash flow, Silver Wheaton's strong production growth profile directly
translates into higher dividends, with $0.35 per common share paid during
2012, almost double what was paid in 2011, and our strong fourth quarter
resulted in our first dividend in 2013 being $0.14 per share."

"With the recently announced acquisition of gold streams from Vale S.A.'s
Salobo and Sudbury mines, we are confident that 2013 and beyond will bring
further growth and many new records to Silver Wheaton. While our organic
growth profile now forecasts roughly an 80% increase of silver equivalent
production over the next five years, we firmly believe there are yet more
accretive opportunities for us to further add to our world-class portfolio of
precious metals streams."

Financial Review

Revenues

Revenue was $287.2 million in the fourth quarter of 2012, on silver equivalent
sales of 9.1 million ounces (7.3 million ounces of silver and 33,000 ounces of
gold). This represents a 50% increase from the $191.9 million of revenue
generated in the fourth quarter of 2011, due primarily to a comparable
increase in the number of ounces sold with relatively unchanged gold and
silver prices.

Revenue was $849.6 million for the year ended December 31, 2012, on silver
equivalent sales of 27.3 million ounces (24.8 million ounces of silver and
46,100 ounces of gold). This represents a 16% increase from the $730.0 million
in revenue generated for the year ended December 31, 2011, due primarily to a
30% increase in the number of ounces sold and a 6% increase in the average
realized gold price, which were partially offset by a 10% decrease in the
average realized selling price of silver.

Costs and Expenses

Average cash costs ^[ ^1] in the fourth quarter of 2012 were $4.70 per silver
equivalent ounce, compared with $4.06 during the comparable period of 2011.
This resulted in cash operating margins ^[ ^1] of $26.76 per silver equivalent
ounce, a 5% decrease compared with the fourth quarter of 2011. The slightly
lower margins were primarily a result of the higher production payments
associated with the precious metals stream on Hudbay's 777 mine ($5.90 and
$400 per ounce of silver and gold, respectively).

Average cash costs ^[ ^1] for the year ended December 31, 2012, were $4.30 per
silver equivalent ounce, compared with $4.09 during the comparable period of
2011. This resulted in cash operating margins ^[ ^1] of $26.79 per silver
equivalent ounce, a 12% decrease compared with the year ended December 31,
2011, resulting primarily due to a 10% decrease in the average realized silver
price.

Earnings and Operating Cash Flows

Net earnings in the fourth quarter of 2012 were $177.7 million ($0.50 per
share), compared with net earnings of $144.7 ($0.41 per share) for the same
period in 2011, an increase of 23%. Cash flow from operations in the fourth
quarter of 2012 was $254.0 million ($0.72 per share ^[ ^1] ), compared with
$163.7 million ($0.46 per share ^[ ^1] ) for the same period in 2011, an
increase of 55%. The increase in net earnings and operating cash flows is
primarily attributable to the increase in the amount of gold and silver sold
in the quarter.

Net earnings for the year ended December 31, 2012, were $586.0 million ($1.66
per share), compared with net earnings of $550.0 million ($1.56 per share) for
the same period in 2011, an increase of 7%. Cash flow from operations for the
year ended December 31, 2012, was $719.4 million ($2.03 per share ^[ ^1] )
compared with $626.4 million ($1.77 per share ^[ ^1] ) for the same period in
2011, an increase of 15%. The increase in net earnings and operating cash flow
is primarily attributable to the increase in the amount of gold and silver
sold, slightly offset by the decrease in the average realized silver price.

Balance Sheet

At December 31, 2012, the Company had approximately $778 million of cash on
hand. Subsequent to the year end, Silver Wheaton announced the acquisition of
two gold streams from Vale for a cash consideration of $1.90 billion (plus 10
million Silver Wheaton warrants with a strike price of $65 and a term of 10
years). As part of the funding for this transaction, Silver Wheaton entered
into two new unsecured credit facilities, comprised of (1) a $1 billion
revolving credit facility having a 5 year term (the "Revolving Facility"); and
(2) a $1.5 billion bridge financing facility having a 1 year term (the "Bridge
Facility").The Revolving Facility and Bridge Facility replaced the $400
million Revolver Loan and the Term Loan, with the latter being repaid in full
on February 22, 2013. The $778 million of cash and cash equivalents as at
December 31, 2012 combined with the liquidity provided by the $2.5 billion of
new credit facilities positions the Company well to fund all outstanding
commitments as well as providing flexibility to acquire additional accretive
precious metal stream interests.

Operational Highlights

Attributable silver equivalent production was a record 8.5 million ounces (7.0
million ounces of silver and 26,400 ounces of gold) in the fourth quarter of
2012, a 22% increase compared to the fourth quarter of 2011. In 2012, Silver
Wheaton experienced its fourth year of record annual attributable production
of 29.6 million silver equivalent ounces (26.9 million ounces of silver and
50,000 ounces of gold), a 17% increase compared to 2011.

_____________________________ ^[ ^1] Please refer to non-IFRS measures at the
end of this press release.

Operational highlights for the year ended December 31, 2012 are as follows:

Peñasquito - In 2012, the Peñasquito mine produced 6.6 million ounces of
attributable silver, an increase of 24% over 2011. Though production was
higher than 2011, an unprecedented regional drought resulted in water
shortages causing mill throughput to average 100,000 tonnes per day in 2012,
below the design capacity of 130,000 tonnes per day. As stated in Goldcorp
Inc.'s ("Goldcorp") press release dated January 7, 2013, the Peñasquito mine
continues to be impacted by the drought and as a result, throughput is
expected to average 105,000 tonnes per day in 2013 as additional water wells
are brought into production within the Cedros Basin in addition to new
dewatering wells within the Chile Colorado pit. A water and tailings study to
develop a comprehensive long-term water strategy for the Peñasquito district
is underway and Goldcorp expects this study to be completed during the first
half of 2013.

San Dimas - Attributable production from the San Dimas mine was 5.9 million
ounces ^[ ^1] in 2012, an increase of 6% over 2011. On October 15, 2012,
Primero Mining Corp. ("Primero") announced a mine and mill expansion of San
Dimas. Primero has elected a staged approach to the full expansion and has
approved the expenditure of a total of $14.4 million to expand the San Dimas
mine and mill from 2,000 tonnes per day currently to 2,500 tonnes per day.
Construction of the mine and mill expansion began in October 2012, with an
estimated completion during the first quarter of 2014. A further plant
expansion to 3,000 tonnes per day continues to be assessed and is dependent on
future exploration success by Primero.

Zinkgruvan - Attributable production in 2012 was a record 2.5 million ounces,
an increase of 48% over 2011, due to high ore grades, good recoveries, and
continued strong throughput levels. Production for 2013 is forecast to be 2.4
million ounces as more normalized grades are expected while throughput and
recoveries are expected to remain strong.

Barrick & Pascua-Lama - Silver Wheaton's 2012 attributable production from the
currently producing Barrick silver interests, consisting of Veladero, Lagunas
Norte and Pierina mines, was 2.7 million ounces of silver.

As per Barrick's year-end 2012 MD&A, during the fourth quarter of 2012 Barrick
finalized the cost estimate and schedule for its Pascua-Lama project. Initial
production remains on track for the second half of 2014 and the total
pre-production capital budget remained at $8.0 to $8.5 billion, of which $4.2
billion had been spent as of the end of 2012. At the end of 2012,
construction was approximately 40% complete with the four kilometer long
conveyance tunnel approximately 70% complete. Construction of the primary
crusher in Chile commenced in January 2013, and, in Argentina, construction of
the process plant facility advanced with approximately 60% of structural steel
erected. Also noted in Barrick's 2012 MD&A, Barrick halted all pre-stripping
activities during the fourth quarter as increased dust, exacerbated by
stronger than normal winds, was observed in the open pit area. Regulatory
authorities in Chile subsequently issued an order to suspend pre-stripping
activities until strengthened dust mitigation and control measures could be
implemented. To date, the suspension of pre-stripping has not altered
Barrick's target of first production in the second half of 2014.

Until December 31, 2015, Silver Wheaton will be entitled to all or a portion
of the silver production from Barrick's Veladero, Pierina and Lagunas Norte
mines, to the extent Pascua-Lama is operating below 75% of design capacity.
Once in production, Pascua-Lama is forecast to be one of the largest and
lowest cost gold mines in the world with an expected mine life in excess of 25
years. In its first full five years of operation, Silver Wheaton's
attributable silver production is expected to average nine million ounces
annually.

Produced But Not Yet Delivered   - Payable silver equivalent ounces produced
but not yet delivered to Silver Wheaton by its partners decreased by 1.4
million ounces in the fourth quarter, resulting in a total of approximately
3.8 million payable ounces at December 31, 2012. This was primarily due to
decreases in concentrate inventories at the 777, Yauliyacu, and Peñasquito
mines.

Detailed mine by mine production and sales figures can be found in the
Appendix of this press release and in Silver Wheaton's Management's Discussion
and Analysis ("MD&A") in the 'Results of Operations and Operational Review'
section.

_____________________________ ^[ ^1] Production includes Goldcorp's four year
commitment to deliver to Silver Wheaton 1.5 million ounces of silver per
annum resulting from their sale of San Dimas to Primero.

Developments Subsequent to 2012 Year End

Salobo and  Sudbury  - In February 2013, Silver Wheaton announced a deal
with Vale S.A. to acquire 25% of the life of mine gold production from the
Salobo Mine in Brazil and 70% of the gold production from its Canadian Sudbury
mines for a 20-year term. The Salobo mine, the largest copper deposit ever
found in Brazil, began operating in 2012 at a capacity of 12 million tonnes
per annum (mtpa) of mill throughput capacity. The mine is already undergoing
an expansion to 24 mtpa and is expected to produce approximately 70 thousand
ounces of gold annually for Silver Wheaton for the first ten years of full
production. Sudbury is one of the largest nickel producing areas globally and
has an operating history dating back to 1885. Vale's integrated operations in
Sudbury are amongst the largest in the world and are expected to contribute 50
thousand ounces of gold annually on average over the next 20 years.

2013 and Long-Term Silver Equivalent Production Forecast

Based upon its current agreements -- including the gold streams from Vale's
Salobo and Sudbury mines -- the Company forecasts 2013 attributable production
of approximately 33.5 million silver equivalent ounces, including 145 thousand
ounces of gold. This represents a 13% increase compared to 2012, which is
primarily driven by a full year of production from Hudbay's 777 mine as well
as the addition of gold production from Vale's Salobo and Sudbury mines.

By 2017, based upon its current agreements, annual attributable production is
anticipated to increase by 79% to approximately 53 million silver equivalent
ounces, including 180 thousand ounces of gold. The increase is the result of
the anticipated ramp up of three new mines, including Barrick's Pascua-Lama
project, Hudbay's Constancia project, and Augusta Resource's Rosemont project.
The world-class Pascua-Lama project is forecast to commence production in
mid-2014 and, in its first full five years of operation, will contribute
approximately 9 million ounces of attributable silver production annually to
Silver Wheaton.

Attributable mine-by-mine actual 2011 and 2012 production and forecast 2013
production are as follows:

be taken", "occur" or "be achieved". 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 to be materially different from those expressed or implied by such
forward-looking statements, including but not limited to: fluctuations in the
price of silver and gold; the absence of control over mining operations from
which Silver Wheaton purchases silver or gold and risks related to these
mining operations including risks related to fluctuations in the price of the
primary commodities mined at such operations, actual results of mining and
exploration activities, economic and political risks of the jurisdictions in
which the mining operations are located and changes in project parameters as
plans continue to be refined; and differences in the interpretation or
application of tax laws and regulations; as well as those factors discussed in
the section entitled "Description of the Business - Risk Factors" in Silver
Wheaton's Annual Information Form available on SEDAR at http://www.sedar.com
and in Silver Wheaton's Form 40-F on file with the U.S. Securities and
Exchange Commission in Washington, D.C. Forward-looking statements are based
on assumptions management believes to be reasonable, including but not limited
to: the continued operation of the mining operations from which Silver Wheaton
purchases silver or gold, no material adverse change in the market price of
commodities, that the mining operations will operate and the mining projects
will be completed in accordance with their public statements and achieve their
stated production outcomes, and such other assumptions and factors as set out
herein. Although Silver Wheaton has 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
forward-looking statements will prove to be accurate. Accordingly, readers
should not place undue reliance on forward-looking statements. Silver Wheaton
does not undertake to update any forward-looking statements that are included
or incorporated by reference herein, except in accordance with applicable
securities laws.

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, 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 .

production related to the Yauliyacu mine may have been overstated by a total
of approximately 200,000 ounces for all or some portion of the period between
April 1, 2011 and June 30, 2012. The required adjustments to production, if
any, related to the Yauliyacu mine for these periods will be made once
management completes a review of the timing and amount of any production
variance.

 Non-IFRS Measures

Silver Wheaton has included, throughout this document, certain non-IFRS
performance measures, including (i) operating cash flow per share (basic and
diluted); (ii) average cash costs of silver and gold on a per ounce basis;
(iii) cash operating margin; and (iv) adjusted net earnings and adjusted net
earnings per share.

i.Operating cash flow per share (basic and diluted) is calculated by dividing
   cash generated by operating activities by the weighted average number of
   shares outstanding (basic and diluted). The Company presents operating
   cash flow per share as it believes that certain investors use this
   information to evaluate the Company's performance in comparison to other
   companies in the precious metals mining industry who present results on a
   similar basis.
ii.Average cash cost of silver and gold on a per ounce basis is calculated by
    dividing the total cost of sales, less depletion, by the ounces sold. In
    the precious metals mining industry, this is a common performance measure
    but does not have any standardized meaning. The Company believes that, in
    addition to conventional measures prepared in accordance with IFRS,
    certain investors use this information to evaluate the Company's
    performance and ability to generate cash flow.
iii.Cash operating margin is calculated by subtracting the average cash cost
     of silver and gold on a per ounce basis from the average realized selling
     price of silver and gold on a per ounce basis. The Company presents cash
     operating margin as it believes that certain investors use this
     information to evaluate the Company's performance in comparison to other
     companies in the precious metals mining industry who present results on a
     similar basis.
iv.Adjusted net earnings and adjusted net earnings per share are calculated
    by removing the effects of the non-cash, fair value adjustment on the
    Company's previously issued and outstanding share purchase warrants, which
    had an exercise price denominated in Canadian dollars, from net earnings
    of the Company. These share purchase warrants are classified as a
    financial liability with any fair value adjustments being reflected as a
    component of net earnings. This accounting treatment was applicable to
    the share purchase warrants which expired or were exercised prior to
    December 22, 2010. The Company believes that, in addition to conventional
    measures prepared in accordance with IFRS, the Company and certain
    investors use this information to evaluate the Company's performance.

These non-IFRS measures do not have any standardized meaning prescribed by
IFRS, and other companies may calculate these measures differently. The
presentation of these non-IFRS measures is intended to provide additional
information and should not be considered in isolation or as a substitute for
measures of performance prepared in accordance with IFRS.
