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.
