Third Quarter Operating Asset Highlights

Salobo: In the third quarter of 2022, Salobo produced 44,200 ounces of attributable gold, a decrease of approximately 20% relative to the third quarter of 2021, primarily due to lower grades and recovery. According to Vale S.A.’s (“Vale”), plant performance improved relative to the second quarter of 2022 despite additional planned and corrective maintenance performed in the third quarter. Vale plans for maintenance activities to continue in the fourth quarter of 2022 to further improve plant reliability.

Vale reports that physical completion of the Salobo III mine expansion was 98% at the end of the third quarter. Progress in the third quarter included the primary crushing circuit being fully commissioned, hot commissioning of the conveyor system, and commencement of wet commissioning of the flotation circuit.

Antamina: In the third quarter of 2022, Antamina produced 1.4 million ounces of attributable silver, a decrease of approximately 11% relative to the third quarter of 2021, primarily due to lower grades as per the mine plan.

Peñasquito: In the third quarter of 2022, Peñasquito produced 2.0 million ounces of attributable silver, a decrease of approximately 7% relative to the third quarter of 2021 with lower recovery and grades as per the mine plan.

Constancia: In the third quarter of 2022, Constancia produced 0.6 million ounces of attributable silver and 7,200 ounces of attributable gold, an increase of approximately 8% for silver production and a decrease of approximately 16% for gold production relative to the third quarter of 2021, with the increase in silver being primarily due to higher throughput and the decrease in gold production being primarily due to the mining of lower-grade material resulting from mine sequencing.

Sudbury: In the third quarter of 2022, Vale’s Sudbury mines produced 4,700 ounces of attributable gold, an increase of approximately 3109% relative to the third quarter of 2021, primarily due to operations at the mine being temporarily suspended due to a labour dispute which

  • 3 -

lasted from June 1, 2021 to August 9, 2021. Vale reports that in the third quarter, the first phase of the Copper Cliff Complex South Mine Project was opened, including the development of more than 12km of tunnels to reunite the south and north shafts of the mine, which is expected to nearly double ore production at the Copper Cliff Mine. The Copper Cliff Mine has historically represented approximately 20% of attributable production for Wheaton from Sudbury.

Stillwater: In the third quarter of 2022, the Stillwater mines produced 1,800 ounces of attributable gold and 3,200 ounces of attributable palladium, a decrease of approximately 38% for gold and 37% for palladium relative to the third quarter of 2021. As per Sibanye-Stillwater Limited, regional floods impacted the Stillwater operations on June 13, 2022, including damage to bridges and the access road to the Stillwater mine. Operations at the Stillwater mine, which accounts for 60% of the mined production from the Stillwater operations, were suspended for seven weeks, but resumed on July 29, 2022. Access to the East Boulder mine and the Columbus metallurgical facilities remains intact and both facilities continued operating during the flooding events.

San Dimas: In the third quarter of 2022, San Dimas produced 11,800 ounces of attributable gold, virtually unchanged relative to the third quarter of 2021, primarily due to lower throughput offset by higher grades. According to First Majestic Silver Corp., silver and gold grades were higher in the third quarter compared to the prior quarter due to improvements in dilution control from the long hole stoping in the Jessica and Regina veins and due to initial production from the Perez vein commencing in July.

Other Gold: In the third quarter of 2022, total Other Gold attributable production was 3,700 ounces, a decrease of approximately 46% relative to the third quarter of 2021, primarily due to the closure of the 777 mine in June 2022.

Other Silver: In the third quarter of 2022, total Other Silver attributable production was 1.9 million ounces, a decrease of approximately 8% relative to the third quarter of 2021, primarily due to lower production at Aljustrel (grades) and Stratoni (placed into care and maintenance).

Voisey’s Bay: In the third quarter of 2022, the Voisey's Bay mine produced 226,000 pounds of attributable cobalt, a decrease of approximately 39% relative to the third 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 78% at the end of the third quarter. Progress in the third quarter included surface activities being well advanced with the port fuel tanks installed and Eastern Deeps mine fresh air infrastructure completed, and in the underground, the Reid Brook bulk Material Handling System advancing on schedule.

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.

Curipamba Project: Adventus Mining Corporation (“Adventus”) announced an Investment Protection Agreement commitment declaration by the Government of Ecuador indicating a significant milestone in the development of the Curipamba Project. Adventus plans for a formal construction commencement in the second quarter of 2023.

Portfolio Optimization

Keno Hill: On September 7, 2022, Hecla Mining Company (“Hecla”) completed the previously announced acquisition of all the outstanding common shares of Alexco. In connection with this acquisition, the Company entered into an agreement with Hecla to terminate the Keno Hill PMPA effective September 7, 2022, in exchange for 34,800,989 common shares of Hecla valued at $141 million (the “Hecla shares”5), resulting in an impairment reversal of the Keno Hill PMPA in the amount of $10 million and a gain on disposal of $104 million.

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. Wheaton has agreed to terminate the stream in order to help facilitate the sale by Glencore of the Yauliyacu Mine. As at September 30, 2022, the net termination payment is estimated to be approximately $136 million. The closing of the transaction is contingent on Glencore divesting the Yauliyacu mine by December 31, 2022 and certain other customary conditions. Glencore retains the option to terminate the silver stream even if it does not divest the Yauliyacu mine by December 31, 2022.

Financial Review Revenues

Revenue was $219 million in the third quarter of 2022 representing an 19% decrease from the third quarter of 2021 due primarily to a 12% decrease in the average realized gold equivalent² price; and a 7% decrease in the number of GEOs² sold.

Revenue was $829 million in the nine months ended September 30, 2022, representing a 10% decrease from the comparable period of the previous year due primarily to a 5% decrease in the number of gold equivalent² ounces sold; and a 6% decrease in the average realized gold equivalent² price.

Cash Costs and Margin

Average cash costs¹ in the third quarter of 2022 were $439 per GEO² as compared to $417 in the third quarter of 2021. This resulted in a cash operating margin¹ of $1,137 per GEO² sold, a decrease of 17% as compared with the third quarter of 2021.

Average cash costs¹ for the nine months ended September 30, 2022 were $433 per GEO² as compared to $441 in the comparable period of the previous year. This resulted in a cash operating margin¹ of $1,311 per GEO² sold, a 7% decrease from the comparable period of the previous year.

Balance Sheet (at September 30, 2022)

  • Approximately $495 million of cash on hand.

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

2) 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.

4) 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: Q3-2022 - 412,000 ounces; Q2-2022 - 382,000 ounces; Q1-2022 - 408,000 ounces; Q4-2021 - 544,000 ounces; Q3-2021
