Fourth Quarter Asset Highlights

Salobo: In the fourth quarter of 2020, Salobo produced 62,900 ounces of attributable gold, a decrease of approximately 16% relative to the fourth quarter of 2019 due to lower throughput. According to Vale S.A.'s ("Vale") Fourth Quarter and Year End 2020 Production and Sales Report, throughput at Salobo was impacted due to unscheduled maintenance and an incident which led Vale to review and halt mine and plant activities for a short period, during which changes in maintenance routines were implemented to improve operations and safety conditions. As per Vale's Fourth Quarter and Year End 2020 Performance Report, physical completion of the Salobo III mine expansion was 68% at the end of the fourth quarter.

Sudbury : In the fourth quarter of 2020, Vale's Sudbury mines produced 7,800 ounces of attributable gold, an increase of approximately 20% relative to the fourth quarter of 2019, due primarily to higher recoveries.

San Dimas: In the fourth quarter of 2020, San Dimas produced 11,700 ounces of attributable gold, virtually unchanged relative to the fourth quarter of 2019. As per the San Dimas precious metal purchase agreements ("PMPA"), the fixed gold to silver conversion ratio reverted to 70:1 (from 90:1) on October 14, 2020 after the average gold to silver price ratio over a six-month period fell back below 90:1.

Antamina: In the fourth quarter of 2020, Antamina produced 1.9 million ounces of attributable silver, an increase of approximately 44% relative to the fourth quarter of 2019, primarily due to higher grades and throughput, partially offset by lower recovery.

Stillwater : In the fourth quarter of 2020, the Stillwater mines produced 3,300 ounces of attributable gold and 5,700 ounces of attributable palladium, a decrease of approximately 8% for gold and 6% for palladium relative to the fourth quarter of 2019, primarily due to lower throughput. According to Sibanye-Stillwater Limited's ("Sibanye-Stillwater") Operating and Financial Results for the Six Month and Year Ended 31 December 2020 , throughput was impacted primarily due to the impact of a spike in COVID-19 infections in the fourth quarter of 2020 associated with a severe wave of COVID-19 infections in Montana, USA . Sibanye-Stillwater also reported that after a review of the Blitz project was conducted following the suspension of growth capital activities due to COVID-19, the project is now expected to reach a steady state by 2024, a delay of up to two years. Finally, Sibanye-Stillwater highlighted that the Fill the Mill expansion project at the East Boulder mine was completed on schedule in the fourth quarter of 2020.

Constancia: In the fourth quarter of 2020, Constancia produced 0.5 million ounces of attributable silver and 3,900 ounces of attributable gold, a decrease of approximately 24% and 17%, respectively, relative to the fourth quarter of 2019, primarily due to lower grades. As per Wheaton's PMPA with Hudbay Minerals Inc. ("Hudbay"), the failure to achieve a minimum level of throughput at the Pampacancha deposit during 2019 entitled Wheaton to an additional 8,020 ounces of gold in 2020 (received in quarterly installments), of which 2,005 ounces of gold was received during the fourth quarter of 2020 and included as production. According to Hudbay's Fourth Quarter MD&A, Hudbay had completed the Consulta Previa consultation process for Pampacancha and received the final mining permit for the development and operation of the mine. In addition, pre-development activities commenced in early January and pre-stripping activities are expected to begin once the remaining individual land user agreement has been completed. Hudbay expects production at Pampacancha to commence later in 2021.

Other Gold : In the fourth quarter of 2020, total Other Gold attributable production was 3,700 ounces, a decrease of approximately 41% relative to the fourth quarter of 2019, primarily due to lower production from the 777 and Minto mines. Hudbay reported on November 25, 2020 , that production at 777 had recommenced after a temporary interruption due to an incident that occurred on October 9, 2020 , during routine maintenance of the hoist rope and skip.

Keno Hill Restart : Alexco Resource Corp ("Alexco") reported on November 24, 2020 , that the commissioning of the Keno Hill District mill is commencing as scheduled, with initial production of lead/silver and zinc concentrates underway. In order to help facilitate the resumption of mining, Wheaton agreed to modify the PMPA as it relates to the delivery payment per ounce of silver in exchange for 2 million common share purchase warrants from Alexco.

Produced But Not Yet Delivered 4

As at December 31, 2020 , payable ounces attributable to the Company produced but not yet delivered amounted to:

• 71,600 payable gold ounces, a decrease of 4,200 ounces during Q4 2020, primarily due to a reduction during the period relative to the Minto , 777 and Sudbury mines partially offset by an increase at the Salobo mine.
• 4.5 million payable silver ounces, an increase of 1.0 million ounces during Q4 2020, primarily due to an increase during the period relative to the Peñasquito, Yauliyacu and Antamina mines.
• 5,600 payable palladium ounces, an increase of 1,000 ounces during Q4 2020.

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, 2019 and other continuous disclosure documents filed by Wheaton since January 1, 2020 , 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 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 .

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