●	Events Subsequent to the Quarter

o	Hudbay Minerals Inc.’s (“Hudbay”) Constancia mine in Peru achieved commercial production on April 30, 2015.

“Silver Wheaton had a strong start to 2015, with record production in the first quarter and the addition of more gold from one of our cornerstone assets. For the first time in our history, Silver Wheaton produced over ten million silver equivalent ounces in one quarter. While the quarterly sales volumes did not reflect the record production, we recognize that this is simply a timing issue and we fully expect to see increased sales as the year progresses,” said Randy Smallwood, President and Chief Executive Officer of Silver Wheaton. “Our record first quarter production was driven by the recent acquisition of an additional 25% of gold from the Salobo mine in Brazil, as well as the first contributions of gold and silver from the Constancia mine in Peru. We expect both of these streams to realize further gains over the coming year, as the Salobo mine is currently ramping-up production after expanding in the middle of last year and the Constancia mine achieved commercial production on April 30th of this year. We also continue to see some very good opportunities to add additional accretive ounces to our existing portfolio. Overall, the first quarter represents a strong start to what we believe will be a prolonged period of significant organic growth for Silver Wheaton without requiring any further capital.”

Financial Review

Revenues

Revenue was $130.5 million in the first quarter of 2015, on silver equivalent sales of 7.7 million ounces (5.7 million ounces of silver and 28,400 ounces of gold). This represents a 21% decrease from the $165.4 million of revenue generated in the first quarter of 2014 due primarily to a 17% decrease in the average realized silver equivalent price ($16.90 in Q1 2015 compared with $20.38 in Q1 2014), coupled with a 5% decrease in the number of silver equivalent ounces sold.

Costs and Expenses

Average cash costs1 in the first quarter of 2015 were $4.46 per silver equivalent ounce as compared with $4.57 during the comparable period of 2014. This resulted in a cash operating margin¹ of $12.44 per silver equivalent ounce, a reduction of 21% as compared with Q1 2014. The decrease in the cash operating margin was primarily due to a 17% decrease in the average silver equivalent price realized in Q1 2015 compared with Q1 2014.

Earnings and Operating Cash Flows

Net earnings and cash flow from operations in the first quarter of 2015 were $49.4 million ($0.13 per share) and $89.1 million ($0.24 per share¹), compared with $79.8 million ($0.22 per share) and $114.8 million ($0.32 per share¹) for the same period in 2014, a decrease of 38% and 22%, respectively. Earnings and cash flow continued to be impacted by lower gold and silver prices.

Balance Sheet

At March 31, 2015, the Company had approximately $88.0 million of cash on hand and $800 million outstanding under the Company's $2 billion revolving term loan.

As per the Company’s February 27, 2015, news release, Silver Wheaton amended its Revolving Facility by increasing the available credit from $1 billion to $2 billion and extending the term by two years, with the facility now maturing on February 27, 2020. As part of the amendment, the financial covenants were revised. The interest rate applicable to any drawings under the amended Revolving Facility remains unchanged. The Company used proceeds drawn from this amended Revolving Facility together with cash on hand to repay the $1 billion of debt previously outstanding under its non-revolving term loan and terminated that loan.

On March 2, 2015, the Company announced that it had entered into an agreement with a syndicate of underwriters led by Scotiabank, pursuant to which they had agreed to purchase, on a bought deal basis, 38,930,000 common shares of Silver Wheaton at a price of $20.55 per share (the “Offering”), for aggregate gross proceeds to Silver Wheaton of approximately $800 million. On March 17, 2015, the Company announced that it had closed the Offering and received $800 million in gross proceeds (net proceeds of approximately $769 million after payment of underwriters’ fees and expenses). The net proceeds were used to help fund the Company’s acquisition of an additional 25% gold stream from the Salobo mine.

First Quarter Asset Highlights

During the first quarter of 2015, attributable silver equivalent production was 10.4 million ounces (6.3 million ounces of silver and 55,100 ounces of gold), representing an increase of 15% compared with the first quarter of 2014.

Operational highlights for the quarter ended March 31, 2015, are as follows:

Salobo

In the first quarter of 2015, Salobo produced 27,185 ounces of gold attributable to Silver Wheaton, an increase of approximately 205% relative to the first quarter of 2014 primarily due to the doubling of the percentage of gold Silver Wheaton is entitled to as detailed below and the increased throughput as a result of the expansion to 24 million tons per annum (“Mtpa”) which commenced production mid-year 2014.

On March 2, 2015, the Company amended the agreement with Vale to acquire an additional amount of gold equal to 25% of the life of mine gold production from any minerals from the Salobo mine that enter the Salobo mineral processing facility from and after January 1, 2015. This acquisition is in addition to the 25% of the Salobo mine gold production that the Company acquired pursuant to the agreement in 2013. Silver Wheaton is now entitled to a total of 50% of the life of mine gold production from the Salobo mine.

Under the amended agreement, the Company paid Vale upfront cash consideration of $900 million and will pay ongoing payments of the lesser of $400 per ounce of gold (subject to an inflationary adjustment of 1% commencing as of January 1, 2017) for the full 50% of gold production or the prevailing market price per ounce of gold delivered. The additional 25% life of mine production that was processed from and after January 1, 2015, accrued retroactively to the Company. If throughput capacity is expanded above the current 24 Mpta within a predetermined period, the Company will be required to make an additional payment to Vale, relative to the 50% stream, based on a set fee schedule.

Constancia

As disclosed in Hudbay’s first quarter of 2015 MD&A, the Constancia mine achieved commercial production on April 30, 2015. Hudbay reported that ocean shipments began in April 2015 and that the mine and concentrator are currently operating at or above design capacity. According to Hudbay, the plant is performing as designed and throughput has occasionally exceeded design due to favourable ore characteristics, with peaks of over 90,000 tonnes per day. Hudbay has indicated that as at April 30, 2015, 42,575 tonnes of copper concentrate had been produced, of which approximately 20,500 tonnes had been shipped. Hudbay continues to expect the operation to achieve steady state design and feasibility level recoveries of copper in the fourth quarter of 2015.

San Dimas

On August 6, 2010, Goldcorp Inc. (“Goldcorp”) completed the sale of the San Dimas mine to Primero Mining Corp (“Primero”). In conjunction with the sale, Silver Wheaton amended its silver purchase agreement relating to the mine. The term of the agreement, as it relates to San Dimas, was extended to the life of mine. During the first four years following the closing of the transaction, Primero delivered to Silver Wheaton a per annum amount equal to the first 3.5 million ounces of payable silver produced at San Dimas and 50% of any excess, and Silver Wheaton received an additional 1.5 million ounces of silver per annum that was delivered by Goldcorp. According to the amended agreement, beginning on August 6, 2014, the fourth anniversary of the closing, Primero delivers a per annum amount to Silver Wheaton equal to the first 6 million ounces of payable silver produced at San Dimas and 50% of any excess, and Goldcorp's obligation to deliver supplemental silver ceased.

- 5 -

In the first quarter of 2015, San Dimas produced 1.9 million ounces of silver, an increase of approximately 20% relative to the first quarter of 2014. This was primarily due to increased production as a result of the expansion to 2,500 tonnes per day (“tpd”) which was completed early in 2014 and to the sharing threshold increasing to 6 million ounces1. In addition, during the quarter, the San Dimas mill consistently operated above its nameplate capacity of 2,500 tpd with an average throughput of 2,863 tpd, a 30% increase versus Q1 2014. Importantly, the San Dimas mine maintained pace with the mill, achieving record quarterly production of 2,931 tpd, 21% higher than in Q1 20142. Metallurgical recoveries also reverted to their historical high levels with the completion of a final leach tank, averaging 93% for silver in the quarter.

Peñasquito

In the first quarter of 2015, the Peñasquito mine produced 1.4 million ounces of silver attributable to Silver Wheaton, a decrease of approximately 29% relative to the fourth quarter of 2014 due to lower grades being mined and lower metallurgical recoveries. Goldcorp has indicated that it anticipates grades to improve throughout 2015.

As disclosed in Goldcorp’s first quarter of 2015 MD&A, in the first quarter of 2015, Peñasquito commenced a feasibility study on the Metallurgical Enhancement Project ("MEP") which is the combined study to assess the feasibility of the Concentrate Enrichment Project ("CEP") and Pyrite Leach Peñasquito sulphide plant ("Pyrite Leach"). The study will assess the potential for producing saleable copper concentrate (CEP) and the viability of leaching a pyrite concentrate from the zinc flotation tailings (Pyrite Leach). Successful implementation of one or both of these new process improvements has the potential to improve the overall economics and life of mine of Peñasquito. The feasibility study is expected to be complete in early 2016.

Barrick / Pascua-Lama

In the first quarter of 2015, attributable silver production from Barrick was 0.6 million ounces, an increase of approximately 112% relative to the first quarter of 2014 primarily due to higher grades at the Veladero and Lagunas Norte mines.

On January 5, 2015, the Company announced that it had amended its silver purchase agreement related to Barrick’s Pascua-Lama project. The amendment entails Silver Wheaton being entitled to 100% of the silver production from Barrick’s Lagunas Norte, Pierina and Veladero mines until March 31, 2018, an extension of 1 ¼ years, and extending the completion test deadline an additional 2 ½ years to June 30, 2020. As a reminder, if the requirements of the completion test have not been satisfied by the amended completion date, the agreement may be terminated by Silver Wheaton. In such an event, Silver Wheaton will be entitled to the return of the upfront cash consideration of $625 million less a credit for any silver delivered up to that date.

1	In the prior year, the San Dimas mine reached the previous sharing threshold of 3.5 million ounces of silver on March 13, 2014.
2	Primero’s first quarter of 2015 MD&A dated May 6, 2015.

Sudbury

In the first quarter of 2015, Sudbury produced 10,112 ounces of gold, an increase of approximately 57% relative to the first quarter of 2014 primarily due to the commencement of operations at the Totten mine as well as higher gold grades being mined.

Other: Toroparu

On April 22, 2015, the Company amended its early deposit precious metal purchase agreement with Sandspring Resources Ltd. ("Sandspring") to include the acquisition of an amount equal to 50% of the silver production from its Toroparu project (“Toroparu”) located in the Republic of Guyana, South America. Silver Wheaton will pay Sandspring incremental upfront cash payments totaling $5.0 million for 50% of the payable silver production from Toroparu. In addition, Silver Wheaton will make ongoing payments to Sandspring of the lesser of the market price and $3.90 per payable ounce of silver delivered to Silver Wheaton over the life of Toroparu, subject to a 1% annual increase starting on the fourth anniversary of production. Sandspring is entitled to receive US$2.0 million of the incremental US$5.0 million cash payment in four equal installments over the course of 2015, subject to the satisfaction of certain conditions.

Produced But Not Yet Delivered 1

During the first quarter of 2015, payable silver equivalent ounces produced but not yet delivered to Silver Wheaton by its partners increased by 1.6 million ounces to approximately 6.5 million silver equivalent payable ounces at March 31, 2015, primarily related to an increase related to the Salobo gold purchase agreement. Payable ounces produced but not yet delivered to Silver Wheaton are expected to average approximately 2 to 3 months of annualized production but may vary from quarter to quarter due to a number of mining operations factors including mine ramp-up, delays in shipments, etc.

Detailed mine by mine production and sales figures can be found in the Appendix to this press release and in Silver Wheaton’s MD&A in the ‘Results of Operations and Operational Review’ section.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING PRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES: The information contained herein has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). These definitions differ from the definitions in Industry Guide 7 (“SEC Industry Guide 7”) under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”).

- 9 -

Under U.S. standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Also, under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “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 pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, information contained herein that describes the Company’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. United States investors are urged to consider closely the disclosure in the Annual Information Form, a copy of which is available at www.sec.gov.

In accordance with the Company’s MD&A and financial statements, reference to the Company includes the Company’s wholly owned subsidiaries.

1)	All figures in thousands except gold ounces produced and sold.

Ounces produced represent the quantity of silver and gold contained in concentrate or doré prior to smelting or refining deductions. Production figures are based on information provided by the operators of the mining operations to which the silver or gold interests relate or management estimates in those situations where other information is not available. Certain production figures may be updated in future periods as additional information is received.

3)	The ounces produced and sold include ounces received from Goldcorp in connection with Goldcorp’s four year commitment commencing on August 6, 2010 to deliver to Silver Wheaton 1.5 million ounces of silver per annum resulting from their sale of San Dimas to Primero.

4)	Comprised of the Lagunas Norte, Pierina and Veladero silver interests.

5)	Comprised of the Los Filos, Zinkgruvan, Cozamin, Neves-Corvo, Stratoni, Keno Hill, Minto, 777, Aljustrel and Constancia silver interests in addition to the previously owned Mineral Park and Campo Morado silver interests.

6)	Comprised of the Coleman, Copper Cliff, Garson, Stobie, Creighton and Totten gold interests.

7)	Comprised of the Minto and Constancia gold interests.

Gold ounces produced and sold are converted to a silver equivalent basis based on either (i) the ratio of the average silver price received to the average gold price received during the period from the assets that produce both gold and silver; or (ii) the ratio of the price of silver to the price of gold on the date of sale as per the London Bullion Metal Exchange for the assets which produce only gold.

9)	Payable silver equivalent ounces produced but not yet delivered are based on management estimates. These figures may be updated in future periods as additional information is received.

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; and (iii) cash operating margin.

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 management and 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. In addition to conventional measures prepared in accordance with IFRS, management and 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 management and 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.

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. For more detailed information, please refer to Silver Wheaton’s Management Discussion and Analysis available on the Company’s website at www.silverwheaton.com and posted on SEDAR at www.sedar.com.
