• Silver Wheaton's estimated average annual attributable production over the next five years is anticipated to be in line with 2017 production at approximately 29 million ounces of silver and 340,000 ounces of gold.

PROPOSED NAME CHANGE TO WHEATON PRECIOUS METALS

• The Board of Directors has recommended changing the Company's name to Wheaton Precious Metals Corp. to better align the corporate identity with the Company's diverse portfolio of both silver and gold assets. The Company plans to seek shareholder approval for the proposed name change at its annual shareholder meeting in May.

"2016 was a record year for Silver Wheaton on many fronts.  We sold more silver and gold than any other year and produced over 350,000 ounces of gold for the first time," said Randy Smallwood, President and Chief Executive Officer of Silver Wheaton. "In the fourth quarter of 2016, we sold over 7.5 million ounces of silver and over 100,000 ounces of gold. Strong sales and production resulted in operating cash flow reaching $175 million in the fourth quarter alone, and over $580 million in 2016. Our portfolio of low cost, long life assets provides a solid foundation that we believe can continue to deliver strong production, sales, and cash flow."

"Since 2013, our company has seen a marked increase in gold production, and in the second half of 2016, revenue was evenly split between silver and gold. In order to better align our corporate identity with underlying operations while maintaining a link to our past and the innovation that the 'Wheaton' name has become synonymous with, we have recommended changing our name to Wheaton Precious Metals. Over the company's history we have created value through streaming both silver and gold from a diverse portfolio of high-quality assets, and the new name will reinforce our position as the leader in precious metals streaming.

Financial Review

Revenues
Revenue was $258 million in the fourth quarter of 2016, on sales volume of 7.5 million ounces of silver and 108,900 ounces of gold. This represents a 29% increase from the $200 million of revenue generated in the fourth quarter of 2015 due primarily to (i) a 68% increase in the number of gold ounces sold; (ii) a 15% increase in the average realized silver price ($16.95 in Q4 2016 compared with $14.75 in Q4 2015); (iii) a 10% increase in the average realized gold price ($1,205 in Q4 2016 compared with $1,100 in Q4 2015); partially offset by (iv) a 14% decrease in the number of silver ounces sold.

Revenue was $892 million in the year ended December 31, 2016, on sales volume of 28.3 million ounces of silver and 330,000 ounces of gold. This represents a 37% increase from the $649 million of revenue generated in 2015 due primarily to (i) a 63% increase in the number of gold ounces sold; (ii) an 8% increase in the average realized silver price ($16.96 in 2016 compared with $15.64 in 2015); (iii) an 8% increase in the average realized gold price ($1,246 in 2016 compared with $1,152 in 2015); and (iv) a 7% increase in the number of silver ounces sold.

Costs and Expenses
Average cash costs² in the fourth quarter of 2016 were $4.59 per silver ounce sold and $389 per gold ounce sold, as compared with $4.06 per silver ounce and $396 per gold ounce during the comparable period of 2015. This resulted in a cash operating margin² of $12.36 per silver ounce sold and $817 per gold ounce sold, an increase of 16% for both as compared with Q4 2015. The increase in the cash operating margin was primarily due to a 15% increase in the average realized silver price and a 10% increase in the average realized gold price in Q4 2016 compared with Q4 2015.

Average cash costs² during the year ended December 31, 2016 were $4.42 per silver ounce sold and $391 per gold ounce sold, as compared with $4.17 per silver ounce and $393 per gold ounce during the comparable period of 2015. This resulted in a cash operating margin² of $12.54 per silver ounce sold and $855 per gold ounce sold, an increase of 9% and 13%, respectively, as compared with 2015. The increase in the cash operating margin was primarily due to an 8% increase in the average realized silver price and an 8% increase in the average realized gold price in 2016 compared with 2015.

Earnings and Operating Cash Flows
Adjusted net earnings² and cash flow from operations in the fourth quarter of 2016 were $82 million ($0.19 per share) and $175 million ($0.40 per share²), compared with adjusted net earnings² of $57 million ($0.14 per share) and cash flow from operations of $133 million ($0.33 per share²) for the same period in 2015, an increase of 43% and 31%, respectively.

Adjusted net earnings² and cash flow from operations for the year ended December 31, 2016 were $266 million ($0.62 per share) and $584 million ($1.36 per share²), compared with adjusted net earnings² of $210 million ($0.53 per share) and cash flow from operations of $431 million ($1.09 per share²) for the same period in 2015, an increase of 27% and 35%, respectively.

Balance Sheet
At December 31, 2016, the Company had approximately $124 million of cash on hand and $1.2 billion outstanding under the Company's $2 billion revolving term loan (the "Revolving Facility"). On February 27, 2017, the term of the revolving term loan was extended so that the term loan now matures on February 27, 2022.

Asset Impairment
At the end of each reporting period, the Company assesses each precious metal purchase agreement to determine whether any indication of impairment exists. If such an indication exists, the recoverable amount of the precious metal purchase agreement is estimated in order to determine the extent of the impairment (if any).

Vale has recently completed a detailed study on the Sudbury mines in an effort to improve operating margins. This has resulted in a number of changes to Vale's anticipated mine plan, with the resulting 2017 to 2032 mine plan having approximately 20% less recoverable gold production than previously estimated, and this reduction in recoverable ounces is an indicator of impairment related to the Sudbury gold interest as at December 31, 2016. The Sudbury gold interest had a carrying value at December 31, 2016 of $473 million. Management has estimated that the recoverable amount at December 31, 2016 under the Sudbury gold interest was $402 million, representing its fair value less cost to sell and resulting in an impairment charge of $71 million.

Fourth Quarter Asset Highlights

During the fourth quarter of 2016, attributable production was 7.6 million ounces of silver and 107,300 ounces of gold, respectively, representing a decrease of 26% and an increase of 48%, as compared with the fourth quarter of 2015.

Operational highlights for the quarter ended December 31, 2016, are as follows:

Salobo 
In the fourth quarter of 2016, Salobo produced 71,328 ounces of attributable gold, an increase of approximately 81% relative to the fourth quarter of 2015. This growth was primarily due to the acquisition of an additional 25% of attributable gold from the Salobo mine in the third quarter of 2016 as well as increased throughput.  According to Vale's fourth quarter production report, production of copper in concentrate at Salobo reached a quarterly record in the fourth quarter with December also achieving a monthly production record.

Antamina
In the fourth quarter of 2016, Antamina produced 1.6 million ounces of attributable silver, a decrease of approximately 33% relative to the fourth quarter of 2015. The apparent significant decrease relative to the fourth quarter of 2015 was primarily attributed to the Antamina transaction being closed in the fourth quarter of 2015 with a term that entitled Silver Wheaton to Glencore's portion of silver sold from Antamina to on offtaker as of September 30, 2015, resulting in reported production in the fourth quarter of 2015 including some material processed in the previous quarter. It should be noted that Antamina produced 6.8 million ounces of silver in 2016, well exceeding expectations and full year guidance of approximately 5.5 million ounces.

Peñasquito 
In the fourth quarter of 2016, Peñasquito produced 1.3 million ounces of attributable silver, a decrease of approximately 25% relative to the fourth quarter of 2015. The drop in production was attributable to lower grades as a result of mine sequencing. As disclosed in Goldcorp Inc.'s ("Goldcorp") fourth quarter of 2016 MD&A, the Pyrite Leach Project ("PLP") achieved 65% engineering progress by the end of 2016, with procurement activities well advanced to support execution. Goldcorp further reports that as part of the PLP, a carbon pre-flotation facility is being constructed and is anticipated to be completed in the second quarter of 2018. The Northern Well Field project has also reportedly reached full production capacity during the fourth quarter of 2016 and is expected to satisfy Peñasquito's long-term water requirements.

San Dimas
In the fourth quarter of 2016, San Dimas produced 1.4 million ounces of attributable silver, a decrease of approximately 38% relative to the fourth quarter of 2015. The decrease in production was primarily driven by lower throughput and grades. As per Primero Mining Corp.'s ("Primero") fourth quarter of 2016 MD&A, production in 2016 was impacted by the implementation of enhanced ground support in early-2016, and later by high unplanned worker absences and lack of compliance to the mine plans. This reportedly resulted in reduced underground development rates and ventilation restrictions which reduced mine productivity. Starting in late-2016, Primero reportedly began undertaking actions to reduce the complexity and scale of the San Dimas mine operations, including significant decreases to the San Dimas workforce. Mining development during Q4 was reportedly the highest quarterly total since Q2 2015. 

On February 15, 2017, Primero announced that unionized employees at the San Dimas mine had initiated a strike action, resulting in the complete stoppage of mining and milling activities at the San Dimas mine. Primero has noted that its key focus in these negotiations has been to better align the short-term bonus structure with overall mine-site performance and profitability, to move the labour force onto a more continuous shift cycle to improve productivity and to achieve the necessary reductions to the unionized workforce.  Primero has indicated that depending on its duration, the strike could have a negative impact on Primero's 2017 production.

As was further noted in Primero's fourth quarter of 2016 MD&A, Primero has commenced a strategic review process to explore alternatives as there is material uncertainty related to the company's ability to continue as a going concern.

Sudbury
In the fourth quarter of 2016, Vale's Sudbury mines produced 11,028 ounces of attributable gold, a decrease of approximately 19% relative to the fourth quarter of 2015. This decrease was attributable to lower throughput and grades. According to Vale's fourth quarter production report, Sudbury production was adversely impacted in the quarter by operational issues and by mine redesign and remediation work. Furthermore, Sudbury will transition to a single furnace operation during 2017 and, as preparation for this, Vale will take one of the furnaces off-line in mid-March in order to rebuild and expand the furnace. The rebuilt furnace will reportedly remain in operation post the transition to one furnace in the second half of the year.  Subsequent to quarter end, Vale announced that the Stobie mine, one of the six currently operating mines from which Silver Wheaton is entitled to gold production, will be placed on care and maintenance later in 2017 due to a number of factors including low metal prices and ongoing market challenges, declining ore grades, and, more recently, seismicity issues that restricted production below the 3,000-foot level. The Stobie mine represented approximately 5% of Silver Wheaton's attributable production from Sudbury.

Other Gold
In the fourth quarter of 2016, total Other Gold attributable production was 21,825 ounces, an increase of 49% relative to the fourth quarter of 2015. The increase was driven primarily by higher grades at Minto and, to a lesser extent, better recoveries at 777.  

Other Silver
In the fourth quarter of 2016, total Other Silver attributable production was 2.5 million ounces, a decrease of approximately 21% relative to the fourth quarter of 2015. The decrease was driven primarily due to lower silver grades at Zinkgruvan, Cozamin, and Veladero. In addition, as per the amendment to the silver stream agreement dated November 30, 2015, production from Yauliyacu was split evenly with Glencore for the entire fourth quarter of 2016 as the mine reached the annual sharing threshold of 1.5 million ounces in the third quarter of 2016.

Development Update – Pascua Lama
As per Barrick Gold Corporation's ("Barrick") news release "Barrick Reports Progress on Projects" dated February 15, 2017, Barrick has initiated a prefeasibility study to evaluate the construction of an underground mine at Lama. Barrick has indicated that the study will evaluate the use of low-cost bulk mining methods, including sub-level cave and block cave mining, designed to target higher-value ore on the Argentinean side of the border in the initial stages of the operation. According to Barrick, cash flow from Lama could support a staged development that would, over time, incorporate ore from the Chilean side of the border, subject to additional permitting in Chile. Barrick's efforts in Chile in 2017 will reportedly focus on advancing project concepts in parallel with the Lama study, with the intention of moving to a prefeasibility level study in 2018. According to Barrick, conceptually, initial ore processing at Lama would be undertaken using one of three partially completed processing streams at the site, which currently has a capacity of approximately 15,000 tonnes per day; existing infrastructure could potentially be scaled up to 25,000 tonnes per day at a later date. Furthermore, Barrick states that an underground mine would reduce the surface footprint of the operation and would be less susceptible to weather-related production interruptions during the winter season.

Produced But Not Yet Delivered ³
As at December 31, 2016, payable ounces attributable to the Company produced but not yet delivered³ amounted to 3.2 million payable silver ounces and 61,700 payable gold ounces, representing a decrease of 0.6 million payable silver ounces and 2,200 payable gold ounces during the three month period ended December 31, 2016. Payable silver ounces produced but not yet delivered decreased primarily as a result of decreases related to the Yauliyacu, Zinkgruvan, and San Dimas silver interests, partially offset by an increase related to the Antamina silver interest. Payable gold ounces produced but not yet delivered decreased primarily as a result of decreases related to the Salobo and Minto gold interests, offset partially by an increase related to the 777 gold interest. Payable ounces produced but not yet delivered to Silver Wheaton companies are expected to average approximately two months of annualized production but may vary from quarter to quarter due to a number of mining operation factors including mine ramp-up and timing of shipments.

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

Reserves and Resources

As of December 31, 2016, Proven and Probable Mineral Reserves attributable to Silver Wheaton were 735.6 million ounces of silver compared with 775.3 million ounces as reported in Silver Wheaton's 2015 Annual Information Form ("AIF"), a decrease of 5%, and 11.55 million ounces of gold compared with 8.79 million ounces, an increase of 31%. On an attributable Measured and Indicated Mineral Resource basis, silver resources were 783.6 million ounces compared with 675.4 million ounces as reported in Silver Wheaton's 2015 AIF, an increase of 16%, and gold resources were 3.05 million ounces compared with 2.70 million ounces, an increase of 13%. On an attributable Inferred Mineral Resource basis, silver resources were 392.1 million ounces compared with 473.5 million as reported in Silver Wheaton's 2015 AIF, a decrease of 17%, and gold resources were 2.85 million ounces compared with 2.38 million ounces, an increase of 20%. 

Estimated attributable reserves and resources contained in this press release are based on information available to the Company as of March 2, 2017, and therefore will not reflect updates, if any, after that date. Updated reserves and resources data incorporating year-end 2016 estimates will also be included in the Company's 2016 Annual Information Form. Silver Wheaton's most current attributable reserves and resources, as of December 31, 2016, can be found on the Company's website at www.silverwheaton.com.

2017 and Long-Term Production Forecast

Silver Wheaton is pleased to provide its updated one-year and long-term production guidance. Silver Wheaton's estimated attributable silver and gold production in 2017 is forecast to be 28 million silver ounces and 340,000 gold ounces. For 2017 guidance, Silver Wheaton has assumed the ongoing strike at San Dimas will continue for a three-month period and that San Dimas will otherwise achieve production in line with 2016. Estimated average annual attributable silver and gold production over the next five years (including 2017) is anticipated to be approximately 29 million silver ounces and 340,000 gold ounces per year.  

Over the next five years, forecast production growth from Salobo, Peñasquito, and Constancia is expected to be offset by the cessation of production from assets with fixed terms. In particular, the 10-year-term contract on Capstone Mining's Cozamin mine, acquired with Silver Wheaton's 2009 acquisition of Silverstone, expires in April 2017. In addition, Silver Wheaton's streaming agreement with Barrick regarding Pascua-Lama provides the Company with silver production from the Lagunas Norte, Veladero, and Pierina mines until March 31, 2018. In addition, Hudbay's Constancia mine satisfied its completion test in 2016, resulting in gold production from the 777 mine attributable to Silver Wheaton dropping from 100% to 50% in 2017. And lastly, as a reminder, Silver Wheaton does not include any production from Barrick's Pascua-Lama project or Hudbay's Rosemont project in its guidance.

Attributable mine-by-mine actual 2015 and 2016 production and forecast 2017 production are as follows:

 

Silver Wheaton to Rename Company to Wheaton Precious Metals

The Company plans to seek shareholder approval to change its name to Wheaton Precious Metals Corp. at its annual shareholder meeting in May.

Since 2013, the Company has seen a marked increase in gold production, and in the second half of 2016, revenue was evenly split between silver and gold. In order to better align the Company's corporate identity with underlying operations, the Board of Directors has recommended that the name be changed to Wheaton Precious Metals Corp. Silver continues to be a focus for the Company; however, the new name will more accurately reflect the Company's diverse portfolio of both silver and gold assets.

If the name change to Wheaton Precious Metals is approved by shareholders, the Company plans to also change its Toronto Stock Exchange ("TSX") and New York Stock Exchange ("NYSE") ticker symbol from "SLW" to "WPM."  The timing of the name change and ticker symbol change will be announced at a later date. Concurrent with the name change, the Company's web domain will also change to www.wheatonpm.com.

Outlook

From a liquidity perspective, the $124 million of cash and cash equivalents as at December 31, 2016 combined with the liquidity provided by the available credit under the $2 billion Revolving Facility and ongoing operating cash flows positions the Company well to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive precious metals stream interests.

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, 2016 to be filed on or before March 31, 2017 and other continuous disclosure documents filed by Silver Wheaton since January 1, 2017, 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 Resources: 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"). 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 Silver Wheaton'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 Silver Wheaton's Form 40-F, a copy of which may be obtained from Silver Wheaton or from http://www.sec.gov/edgar.shtml.

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