Wheaton Precious Metals Announces Third Quarter Results for 2018 and Declares Fourth Quarterly Dividend of 2018

On track to exceed annual production guidance

VANCOUVER, Nov. 15, 2018 - Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") (TSX: WPM ) (NYSE: WPM) is pleased to announce its results for the third quarter ended September 30, 2018. All figures are presented in United States dollars unless otherwise noted.

In the third quarter of 2018, Wheaton generated close to $110 million in operating cash flow, and completed the acquisition of a gold and palladium stream on the Stillwater and East Boulder mines (collectively "Stillwater"). During the third quarter, Wheaton received its first deliveries of gold and palladium from Stillwater. Through the first nine months of 2018, Wheaton had record gold production and sales volumes, and is on track to meet annual production guidance, and is currently on track to exceed annual production guidance.

Operational Overview

Highlights

• The decrease in attributable silver production for the three months ended September 30, 2018, was primarily due to the termination of the San Dimas silver purchase agreement and the entering into of the new San Dimas precious metals purchase agreement ("First Majestic PMPA") effective May 10, 2018, the expiry of the streaming agreement relative to the Lagunas Norte, Veladero and Pierina mines on March 31, 2018, and lower production at Peñasquito due to lower throughput and planned lower grades from stockpiles during the commissioning of the now fully constructed Peñasquito Pyrite Leach Project ("PLP").
• The increase in attributable gold production for the three months ended September 30, 2018, was primarily due to the entering into of the First Majestic PMPA, the acquisition of the new gold stream at Stillwater, partially offset by lower production at both Salobo and Minto.
• The decrease in silver sales volume for the three months ended September 30, 2018, was due to the lower production levels, partially offset by positive changes in the balance of payable silver produced but not yet delivered to Wheaton.
• The increase in gold sales volume for the three months ended September 30, 2018, was primarily the result of increased production levels coupled with positive changes in the balance of payable gold produced but not yet delivered to Wheaton.
• Declared quarterly dividend of $0.09 per common share.
• On July 25, 2018, the Company, through its wholly owned subsidiary Wheaton Precious Metals International Ltd. ("Wheaton International"), completed the acquisition from Sibanye Gold Limited ("Sibanye-Stillwater") of a fixed percentage of gold and palladium production from Stillwater effective July 1, 2018.

Reconfirming 2018 Production Guidance

·   Wheaton's estimated attributable production in 2018 is on track to exceed its guidance of approximately 355,000 ounces of gold, 22.5 million ounces of silver and 10,400 ounces of palladium.

Subsequent to the Quarter

·   On October 24, 2018, Vale S.A. ("Vale") announced the approval of the Salobo III mine expansion, which if completed as proposed, would increase processing throughput capacity from 24 million tonnes per annum ("Mtpa") to 36 Mtpa once fully ramped up (the "Salobo Expansion").

"Our robust precious metals business continued to grow in the third quarter with the first production of gold and palladium from our latest stream, Stillwater, exceeding our expectations. With the addition of Stillwater, Wheaton had record gold production and sales volume in the first nine months of 2018 resulting in operating cash flow of almost $370 million." said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. "In addition, we believe we are currently well positioned to exceed our production guidance for 2018. Finally, we also look forward to Vale pursuing their announced expansion of the Salobo mine in Brazil. Salobo has proven itself to be an exceptional mine, delivering metal to both Vale and Wheaton at a low cost."

Financial Review

Revenues
Revenue was $186 million in the third quarter of 2018, on sales volume of 5.0 million ounces of silver, 89,200 ounces of gold and 3,700 ounces of palladium. This represents a 9% decrease from the $203 million of revenue generated in the third quarter of 2017 due primarily to (i) a 13% decrease in the number of silver ounces sold; (ii) a 12% decrease in the average realized silver price ($14.80 in Q3 2018 compared with $16.87 in Q3 2017); and (iii) a 6% decrease in the average realized gold price ($1,210 in Q3 2018 compared with $1,283 in Q3 2017); partially offset by (iv) an 8% increase in the number of gold ounces sold; and (v) the first sales of palladium.

Costs and Expenses
Average cash costs¹ in the third quarter of 2018 were $5.04 per silver ounce sold, $418 per gold ounce sold and $169 per palladium ounce sold, as compared with $4.43 per silver ounce and $396 per gold ounce during the comparable period of 2017. This resulted in a cash operating margin¹ of $9.76 per silver ounce sold, $792 per gold ounce sold and $786 per palladium ounce sold, a reduction of 22% and 11% for silver and gold, respectively, as compared with Q3 2017. The decrease in the cash operating margin was primarily due to a 12% decrease in the average realized silver price and a 6% decrease in the average realized gold price in Q3 2018 compared with Q3 2017.

Earnings and Operating Cash Flows
Adjusted net earnings¹ and cash flow from operations in the third quarter of 2018 were $35 million ($0.08 per share) and $108 million ($0.24 per share¹), compared with $67 million ($0.15 per share) and $129 million ($0.29 per share¹) for the same period in 2017, a decrease of 47% and 16%, respectively.

Balance Sheet
At September 30, 2018, the Company had approximately $119 million of cash on hand and $1.4 billion outstanding under the Company's $2 billion revolving term loan (the "Revolving Facility").

Third Quarter Asset Highlights

During the third quarter of 2018, attributable production was 5.7 million ounces of silver, 101,600 ounces of gold and 8,800 ounces of palladium, representing a decrease of 25% and an increase of 7% for silver and gold, respectively, as compared with the third quarter of 2017.

Operational highlights for the quarter ended September 30, 2018, based upon counterparties' reporting, are as follows:

Salobo  
In the third quarter of 2018, Salobo produced 68,600 ounces of attributable gold, a decrease of approximately 6% relative to the third quarter of 2017 due to slightly lower grades as expected due to mine sequencing in the open pit. As discussed below, subsequent to the quarter, Vale announced the approval of the Salobo Expansion.

Peñasquito 
In the third quarter of 2018, Peñasquito produced 1.0 million ounces of attributable silver, a decrease of approximately 36% relative to the third quarter of 2017 due to lower throughput and planned lower grades from stockpiles during the commissioning of the now fully constructed PLP. According to Goldcorp Inc.'s ("Goldcorp") third quarter of 2018 MD&A, lower production was a result of the planned transition from higher grade ore in the Peñasco pit to lower grade ore from stockpiles during the first three quarters of 2018. This transition facilitated the stripping campaign in the Peñasco pit and the pre-stripping campaign in the newly developed Chile Colorado pit. Goldcorp further notes that production in the third quarter of 2018 was impacted by a reduction in mill throughput as much harder low-grade stockpiles were processed during commissioning of the Carbon Pre-flotation plant, a component of the PLP.

According to Goldcorp, commissioning of the PLP commenced, with commercial production expected in the fourth quarter of 2018. In addition, Goldcorp reports that substantially all of Peñasquito's production in the fourth quarter will come from higher grade ore from the main Peñasco pit.

Antamina
In the third quarter of 2018, Antamina produced 1.5 million ounces of attributable silver, a decrease of approximately 15% relative to the third quarter of 2017 as expected due to mine sequencing in the open pit.

San Dimas
In the third quarter of 2018, San Dimas produced 10,600 ounces of attributable gold. According to First Majestic Silver Corp.'s ("First Majestic") third quarter of 2018 production report, silver equivalent production in the quarter increased 90% relative to the prior quarter due to increased throughput as some of the lower grade stopes that were deemed uneconomical under the old streaming agreement have now become economical under the new streaming agreement. First Majestic also highlighted increased recoveries as a result of an additional agitator tank being installed in September which increases retention times.

Sudbury
In the third quarter of 2018, Vale's Sudbury mines produced 6,000 ounces of attributable gold, a decrease of approximately 30% relative to the third quarter of 2017 primarily due to lower throughput caused by a planned maintenance shutdown in August (planned maintenance in 2017 occurred in June).

Constancia
In the third quarter of 2018, Constancia produced 0.7 million ounces of attributable silver and 3,300 ounces of attributable gold, an increase of approximately 19% and 31%, respectively, relative to the third quarter of 2017. Increased silver and gold production was primarily due to record mill throughput and higher grades.

Stillwater
In the third quarter of 2018, Stillwater produced 6,400 ounces of attributable gold and 8,800 ounces of attributable palladium. On July 25, 2018, the Company, through its wholly owned subsidiary Wheaton International, completed the acquisition from Sibanye-Stillwater of a fixed percentage of gold and palladium production from Stillwater. As part of the agreement, Wheaton is entitled to the attributable gold and palladium production for which an offtaker payment was received after July 1, 2018, resulting in reported production for the third quarter including some material processed in the previous quarter. Wheaton's 2018 production guidance for Stillwater was approximately 5,400 ounces of gold and 10,400 ounces of palladium. For more details on the acquisition, please refer to Wheaton's news release dated July 16, 2018.

Other Silver 
In the third quarter of 2018, total Other Silver attributable production was 2.4 million ounces, a decrease of approximately 4% relative to the third quarter of 2017. The decrease was driven primarily by the cessation of attributable production from the Lagunas Norte, Veladero and Pierina mines as the silver purchase agreement with Barrick Gold Corp. ("Barrick") related to these mines expired on March 31, 2018, and lower production at Zinkgruvan, partially offset by the start-up of attributable production at the Aljustrel mine.

Other Gold 
In the third quarter of 2018, total Other Gold attributable production was 6,700 ounces, a decrease of approximately 41% relative to the third quarter of 2017. The decrease was due primarily to lower production at both the 777 and Minto mines. As per Capstone Mining Corp.'s ("Capstone") news release dated October 11, 2018, the agreement under which Capstone had agreed to sell its Minto mine to Pembridge Resources plc has been terminated. In conjunction with this, Capstone has elected to place the Minto mine on care and maintenance while Capstone seeks alternatives to preserve and maximize the value of the Minto mine.

Produced But Not Yet Delivered ²
As at September 30, 2018, payable ounces attributable to the Company produced but not yet delivered amounted to 4.5 million payable silver ounces, 77,100 payable gold ounces and 4,700 payable palladium ounces, representing an increase of 0.2 million payable silver ounces and 100 payable gold ounces during the three-month period ended September 30, 2018. Payable silver ounces produced but not yet delivered increased primarily as a result of increases related to the Peñasquito and Antamina silver interests partially offset by a decrease related to the Yauliyacu silver interest. Payable gold ounces produced but not yet delivered increased primarily as a result of increases related to the Stillwater and Sudbury gold interests partially offset by decreases related to the Minto and 777 gold interests. Payable ounces produced but not yet delivered to the Wheaton group of companies are expected to average approximately two months of annualized production for silver and two to three months for both gold and palladium 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 Wheaton's consolidated MD&A in the 'Results of Operations and Operational Review' section.

Subsequent to the Quarter

Salobo Expansion 
As per Vale's third quarter 2018 MD&A, on October 24, 2018, Vale's Board of Directors approved the Salobo Expansion, a brownfield expansion, which if completed as proposed, would increase processing throughput capacity to 36 Mtpa. Wheaton International first entered into a gold purchase agreement with Vale in respect of the Salobo mine in 2013 and made subsequent amendments to the agreement in 2015 and 2016 (the "Gold Agreement"). As part of the Gold Agreement, if actual throughput is expanded above 28 Mtpa within a predetermined period, and depending on the grade of material processed, Wheaton will be required to make an additional payment to Vale based on a set fee schedule. As proposed, the Salobo Expansion would increase throughput capacity from 24 Mtpa to 36 Mtpa once fully ramped up. Vale has approved the investment of US$1.1 billion in the Salobo Expansion, with a start-up scheduled for the first half of 2022 and an estimated ramp-up of 15 months. Vale has indicated that the Salobo Expansion will encompass a third concentrator and will use Salobo's existing infrastructure. As agreed to as part of the original Gold Agreement and based on Vale's disclosure relating to size and timing of the Salobo Expansion, the Company estimates that an expansion payment of between $550 million to $650 million would be payable. Given Vale's proposed schedule, this payment would likely be made in 2023.

Outlook

Wheaton's estimated attributable production in 2018 is forecast to be approximately 355,000 ounces of gold, 22.5 million ounces of silver, and 10,400 ounces of palladium. Estimated average annual attributable production over the next five years (including 2018) is anticipated to be approximately 385,000 ounces of gold, 25 million ounces of silver, 27,000 ounces of palladium, and starting in 2021, 2.1 million pounds of cobalt per year. As a reminder, Wheaton does not include any production from Barrick's Pascua-Lama project or Hudbay's Rosemont project in its estimated average five-year production guidance.

From a liquidity perspective, the $119 million of cash and cash equivalents as at September 30, 2018 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 metal stream interests.

Non-IFRS Measures

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

i. Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of the non-cash impairment charges, non-cash fair value (gains) losses, non-cash share of losses of associates and other one-time (income) expenses. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, management and certain investors use this information to evaluate the Company's performance.

The following table provides a reconciliation of adjusted net earnings and adjusted net earnings per share (basic and diluted).

ii. 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 metal mining industry who present results on a similar basis.

The following table provides a reconciliation of operating cash flow per share (basic and diluted).

iii. Average cash cost of silver, gold and palladium on a per ounce basis is calculated by dividing the total cost of sales, less depletion, by the ounces sold. In the precious metal 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.

The following table provides a reconciliation of average cash cost of silver, gold and palladium on a per ounce basis.

iv. Cash operating margin is calculated by subtracting the average cash cost of silver, gold and palladium on a per ounce basis from the average realized selling price of silver, gold and palladium 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 metal mining industry who present results on a similar basis as well as to evaluate the Company's ability to generate cash flow.

The following table provides a reconciliation of cash operating margin.

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.
