Fourth Quarter Operating Asset Highlights

Salobo: In the fourth quarter of 2022, Salobo produced 37,900 ounces of attributable gold, a decrease of approximately 21% relative to the fourth quarter of 2021, primarily due to lower throughput and grades. According to Vale S.A.’s (“Vale”), plant availability was impacted due to additional planned and corrective maintenance performed in the fourth quarter.

Vale reports the Salobo III mine expansion project, which will increase the mill throughput by 50%, successfully commenced at the end of 2022. The project consists of two lines, the first of which started up in the fourth quarter of 2022 and the second expected to start in the first quarter of 2023.

Subsequent to the quarter, Wheaton and Vale agreed to amend the Salobo PMPA to adjust the expansion payment terms in order to provide increased flexibility for the ramp-up of the expansion while also maintaining an incentive for Vale to maximize grade on an annual basis. The expansion payment will now be phased, with Wheaton making an initial payment once actual throughput is expanded above 32 million tonnes per annum (“Mtpa”) and a second payment if actual throughput is expanded above 35 Mtpa, by January 1, 2031. The total cumulative payments will range from $283 million to $552 million, dependent at Vale’s timing for each of the production increases. In addition, Wheaton will be required to make annual payments of between $5.1 million to $8.5 million for a 10-year period following payment of the expansion payments if the Salobo mine maintains a high-grade mine plan.

Antamina: In the fourth quarter of 2022, Antamina produced 1.1 million ounces of attributable silver, a decrease of approximately 19% relative to the fourth quarter of 2021, primarily due to lower grades as per the mine plan.

- 2 -

Peñasquito: In the fourth quarter of 2022, Peñasquito produced 1.8 million ounces of attributable silver, a decrease of approximately 18% relative to the fourth quarter of 2021 with lower recovery and grades as per the mine plan.

Constancia: In the fourth quarter of 2022, Constancia produced 0.7 million ounces of attributable silver and 10,500 ounces of attributable gold, an increase of approximately 13% and 6%, respectively, relative to the fourth quarter of 2021, with the increase in silver being primarily due to higher grades and recovery while the increase in gold production being primarily due to the mining of higher-grade material. According to Hudbay Minerals Inc. (“Hudbay”), gold production was lower than expected in the fourth quarter as a result of short-term changes in the mine plan that prioritized the processing of lower grade stockpiles and shorter-haulage distance ore from the Constancia pit versus higher-grade ore from the Pampacancha pit. These changes were implemented by Hudbay to ration fuel during a period of nation-wide social unrest and road blockades following a change in Peru’s political leadership in early December 2022, and ensured the plant continued to operate uninterrupted.

Sudbury: In the fourth quarter of 2022, Vale’s Sudbury mines produced 6,300 ounces of attributable gold, an increase of approximately 45% relative to the fourth quarter of 2021, primarily due to higher throughput as fourth quarter 2021 production was impacted by the temporary closure of the Totten Mine after the shaft was damaged on September 26, 2021.

Stillwater: In the fourth quarter of 2022, the Stillwater mines produced 2,200 ounces of attributable gold and 3,900 ounces of attributable palladium, a decrease of approximately 18% for gold and 18% for palladium relative to the fourth quarter of 2021. As per Sibanye-Stillwater Limited (“Sibanye”), the ramp-up of production post the regional flood event in early June 2022 progressed well, with production rates normalising during Q4 2022. Sibanye continues to reposition the Stillwater operations for the current skills shortage and changing macro environment and expects further normalization of production rates in 2023.

San Dimas: In the fourth quarter of 2022, San Dimas produced 10,000 ounces of attributable gold, a decrease of approximately 27% relative to the fourth quarter of 2021, primarily due to the mining of lower grade material. According to First Majestic Silver Corp., silver and gold grades were impacted primarily due to the processing of lower grade development ores from the Perez vein and higher tonnages from underground areas with challenging ground conditions within the Jessica and Regina veins in the Noche Buena area.

Other Gold: In the fourth quarter of 2022, total Other Gold attributable production was 3,100 ounces, a decrease of approximately 63% relative to the fourth quarter of 2021, primarily due to the closure of the 777 mine in June 2022.

Other Silver: In the fourth quarter of 2022, total Other Silver attributable production was 1.8 million ounces, a decrease of approximately 19% relative to the fourth quarter of 2021, primarily due to the placement of Stratoni into care and maintenance, the closure of the 777 mine and the termination of the Keno Hill and Yauliyacu PMPAs.

Voisey’s Bay: In the fourth quarter of 2022, the Voisey’s Bay mine produced 128,000 pounds of attributable cobalt, a decrease of approximately 66% relative to the fourth quarter of 2021, primarily due to mining lower grade material during the ongoing transitional period between the depletion of the Ovoid open-pit mine and ramp-up to full production of the Voisey’s Bay underground project. Vale reports that physical completion of the Voisey’s Bay underground mine extension was 81% at the end of the fourth quarter. In the second quarter of 2021, Vale achieved

- 3 -

the first ore production from the Reid Brook deposit, the first of two underground mines to be developed in the project. Eastern Deeps, the second deposit, has started to extract development ore from the deposit and is scheduled to start the main production ramp-up in the second half of 2023.

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.

Fourth Quarter Development Asset Highlights

Blackwater Project: Artemis Gold Inc. (“Artemis”) announced that it had executed an order for construction equipment required for major construction activities with the initial fleet expected to be delivered in early Q2 2023. In addition, plant site preparation is well advanced with the majority of the bulk earth works completed, and work on the construction camp is proceeding on schedule with 150 rooms and kitchen facilities on track to be ready for occupation by the end of February. Artemis also announced that it has closed the $385 million project loan facility to fund a significant component of the estimated construction costs of the Blackwater project. On March 9, 2023, Artemis announced the approval of its BC Mines Act Permit for the Blackwater project. The approval of the BC Mines Act Permit is the final step required to allow Artemis to commence major works construction activities at the Blackwater Mine in Q1 2023 with the expectation of an initial gold pour in the second half of 2024.

Copper World Complex: Hudbay reports that it has executed a new strategy at Copper World focused on project de-risking and a two-phase mine plan with the first phase located on private land claims. The pre-feasibility study for Phase I of Copper World is well-advanced with the main facility engineering completed and metallurgical test work being analyzed as part of the concentrate leaching trade off evaluations. The pre-feasibility study is expected to be released in the second quarter of 2023.

Goose Project: Subsequent to the quarter, Sabina Gold & Silver Corp. (“Sabina”) announced that it had entered into a definitive agreement (the “Agreement”) pursuant to which B2Gold Corp. has agreed to acquire all of the issued and outstanding shares of Sabina.

Marathon Project: Generation Mining Limited (“Gen Mining”) announced that the Marathon Project was approved by the joint Federal and Provincial Environmental Assessment process, and that they will now proceed to obtain the necessary permits for construction and operation.

Curipamba Project: Adventus Mining Corporation (“Adventus”) announced that the Government of Ecuador has signed the Investment Contract in support of the development of the El Domo deposit, which is part of the Curipamba Project.

Portfolio Optimization

Yauliyacu: On August 18, 2022, the Company announced that it had entered into an agreement with Glencore plc (“Glencore”) to terminate its silver stream on the Yauliyacu mine in Peru for a cash payment of $150 million, less the aggregate value of any deliveries to Wheaton, prior to closing, of silver produced subsequent to December 31, 2021. The transaction closed on December 6, 2022, and the Company received a cash payment of $132 million. The Yauliyacu PMPA was terminated on December 14, 2022.

Financial Review

About Wheaton Precious Metals Corp. and Outlook

Wheaton is the world’s premier precious metals streaming company with the highest-quality portfolio of long-life, low-cost assets. Its business model offers investors commodity price leverage and exploration upside but with a much lower risk profile than a traditional mining company. Wheaton delivers amongst the highest cash operating margins in the mining industry, allowing it to pay a competitive dividend and continue to grow through accretive acquisitions. As a result, Wheaton has consistently outperformed gold and silver, as well as other mining investments. Wheaton is committed to strong ESG practices and giving back to the communities where Wheaton and its mining partners operate. Wheaton creates sustainable value through streaming for all of its stakeholders.

Wheaton’s estimated attributable production in 2023 as well as the 5-year average and 10-year annual gold equivalent production is as follows:


Metal	2023 Forecast²	5-year Annual Average (2023-2027)^2,5	10-year Annual Average (2023-2032)^2,5
Gold Ounces	320,000 to 350,000
Silver Ounces (‘000s)	20,000 to 22,000
Other Metals (Palladium & Cobalt) (GEOs³)	22,000 to 25,000
Total Gold Equivalent Ounces³	600,000 to 660,000	810,000	850,000

In 2023, gold equivalent production is forecast to be slightly higher than 2022 as expected stronger attributable production from Salobo and Constancia is forecast to be offset by weaker production from Antamina and the termination of the silver stream on Yauliyacu. Attributable production is forecast to increase at Salobo as a result of uninterrupted operations as well as the start-up of the Salobo III mine expansion and at Constancia due to higher grades associated with the mining of the Pampacancha deposit. Attributable production is forecast to decrease a Antamina due to lower grades as per the mine plan.

Average forecast production over the next five years is expected to increase primarily due to anticipated continued production growth from Salobo, Stillwater, Constancia, Voisey’s Bay and Marmato as well as incremental production ounces from Blackwater, Toroparu, Marathon, Copper World Complex and Santo Domingo towards the latter end of the forecast period. Average forecast production over the next ten years includes additional incremental production from the Fenix project, Kutcho project and the Victor mine in Sudbury. Vale S.A. has indicated the potential for an additional expansion after the Salobo III expansion, but Wheaton does not currently include this in its forecast. Lastly, although Barrick Gold Corp. continues to advance a comprehensive review of the Pascua Lama project, Wheaton does not include any production from the project in its estimated average ten-year production guidance.

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

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

3)	Comprised of the Coleman, Copper Cliff, Garson, Creighton and Totten gold interests. Operations at the Sudbury mines were suspended from June 1, 2021 to August 9, 2021 as a result of a labour disruption by unionized employees.

Under the terms of the San Dimas PMPA, the Company is entitled to an amount equal to 25% of the payable gold production plus an additional amount of gold equal to 25% of the payable silver production converted to gold at a fixed gold to silver exchange ratio of 70:1 from the San Dimas mine. If the average gold to silver price ratio decreases to less than 50:1 or increases to more than 90:1 for a period of 6 months or more, then the “70” shall be revised to “50” or “90”, as the case may be, until such time as the average gold to silver price ratio is between 50:1 to 90:1 for a period of 6 months or more in which event the “70” shall be reinstated. Effective April 1, 2020, the fixed gold to silver exchange ratio was revised to 90:1, with the 70:1 ratio being reinstated on October 15, 2020. For reference, attributable silver production from prior periods is as follows: Q4 2022—348,000 ounces; Q3 2022—412,000 ounces; Q2 2022—382,000 ounces; Q1 2022—408,000 ounces; Q4 2021—544,000 ounces; Q3 2021—472,000 ounces; Q2 2021—467,000 ounces; Q1 2021—429,000 ounces..

5)	Comprised of the Stillwater and East Boulder gold and palladium interests.

6)	On June 22, 2022, Hudbay announced that mining activities at 777 have concluded and closure activities have commenced.

7)	Operations at Los Filos were temporarily suspended from June 22, 2021 to July 26, 2021 as the result of illegal blockades by a group of unionized employees and members of the Xochipala community.

8)	On December 14, 2022 the Company terminated the Yauliyacu PMPA in exchange for a cash payment of $132 million.

9)	The Stratoni mine was placed into care and maintenance during Q4-2021.

10)	On September 7, 2022, the Company terminated the Keno Hill stream in exchange for $141 million of Hecla common shares received as consideration.

11)

Effective January 1, 2021, the Company was entitled to cobalt production from the Voisey’s Bay mine. As per the Voisey’s Bay PMPA with Vale, Wheaton is entitled to any cobalt processed at the Long Harbour Processing Plant as of January 1, 2021, resulting in reported production in the first quarter of 2021 including some material produced at the Voisey’s Bay mine in the previous quarter.

12)	GEOs, which are provided to assist the reader, are based on the following commodity price assumptions: $1,800 per ounce gold; $24.00 per ounce silver; $2,100 per ounce palladium; and $33.00 per pound cobalt; consistent with those used in estimating the Company’s production guidance for 2022.

Non-IFRS Measures

Wheaton 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 gold, silver and palladium on a per ounce basis and cobalt on a per pound basis; and (iv) cash operating margin.

Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of non-cash impairment charges (reversals) (if any), non-cash fair value (gains) losses and other one-time (income) expenses as well as the reversal of non-cash income tax expense (recovery) which is offset by income tax expense (recovery) recognized in the Statements of Shareholders’ Equity and OCI, respectively. 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).

Average cash cost of gold, silver and palladium on a per ounce basis and cobalt on a per pound basis is calculated by dividing the total cost of sales, less depletion, by the ounces or pounds sold. In the precious metal mining industry, this is a common performance measure but does not have any standardized meaning prescribed by IFRS. 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 calculation of average cash cost of gold, silver and palladium on a per ounce basis and cobalt on a per pound basis.

Cautionary Language Regarding Reserves And Resources

For further information on Mineral Reserves and Mineral Resources and on Wheaton more generally, readers should refer to Wheaton’s Annual Information Form for the year ended December 31, 2022, which will be filed on or about March 31, 2023 and other continuous disclosure documents filed by Wheaton since January 1, 2023, available on SEDAR at www.sedar.com. 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”). 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. 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. The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. Under the SEC Modernization Rules, the historical property disclosure requirements for mining registrants included in SEC Industry Guide 7 will be rescinded and replaced with disclosure requirements in subpart 1300 of SEC Regulation S-K. Following the transition period, as a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101. As a result of the adoption of the SEC Modernization Rules, the SEC will recognize estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding definitions under the CIM Definition Standards that are required under NI 43-101. However, while the above terms are “substantially similar” to CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM

- 25 -

Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules. Accordingly, information contained herein that describes 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 Wheaton’s Form 40-F, a copy of which may be obtained from Wheaton or from https://www.sec.gov/edgar.shtml.
