Wheaton Precious Metals Announces Solid Start to 2023

“Wheaton’s high-quality portfolio of long-life, low-cost assets delivered a solid performance to start the year, resulting in revenue of $214 million and robust cash operating margins,” said Randy Smallwood, President and Chief Executive Officer of Wheaton Precious Metals. “First quarter production was ahead of Company expectations, and as we continue to see positive developments at a number of our key assets including Salobo and Constancia, we expect to see significant production growth throughout 2023, culminating in a strong second half of the year. Notably, implicit in our five-year annual average production guidance, is an impressive organic growth profile of over 40%, with two-thirds coming from assets already in operation. In addition, our corporate development team remains exceptionally busy evaluating new opportunities, and as always, Wheaton is focused on ensuring our growth is both accretive and sustainable for all of our stakeholders."

Solid Financial Results and Strong Balance Sheet

High Quality Asset Base

Leadership in Sustainability

All amounts in thousands except gold, palladium & gold equivalent ounces, and per share amounts.

Financial Review

Revenues

Revenue was $214 million (56% gold, 40% silver, 2% palladium and 2% cobalt), with the $93 million decrease being primarily due to the cessation of production from Yauliyacu, 777 and Keno Hill coupled with relative changes in the GEOs produced but not yet delivered3 and a 5% decrease in the average realized gold equivalent³ price.

Cash Costs and Margin

Average cash costs¹ in the first quarter of 2023 were $443 per GEO² as compared to $440 in the first quarter of 2022. This resulted in a cash operating margin¹ of $1,384 per GEO³ sold, a decrease of 7% as compared with the first quarter of 2022.

Cash Flow from Operations

Operating cashflow amounted to $135 million, with the $75 million decrease being due primarily to the lower cash operating margin and the payout of the Company’s performance share units in the first quarter of 2023 while in 2022 they were paid in the second quarter.

First Quarter Operating Asset Highlights

Salobo: In the first quarter of 2023, Salobo produced 43,700 ounces of attributable gold, virtually unchanged relative to the first quarter of 2022, with higher grades and throughput offset by lower recovery. According to Vale S.A. (“Vale”), production in the first quarter was impacted by planned and corrective maintenance activities, with additional maintenance planned for the second quarter.

Antamina: In the first quarter of 2023, Antamina produced 0.9 million ounces of attributable silver, a decrease of approximately 31% relative to the first quarter of 2022, primarily due to lower grades as per the mine plan.

Peñasquito: In the first quarter of 2023, Peñasquito produced 2.1 million ounces of attributable silver, a decrease of approximately 6% relative to the first quarter of 2022 due to lower recoveries partially offset by higher grades.

Constancia: In the first quarter of 2023, Constancia produced 0.6 million ounces of attributable silver and 6,900 ounces of attributable gold, an increase of approximately 9% for both metals relative to the first quarter of 2022, with the increase in both metals being primarily due to higher throughput and grades. As per Hudbay, full mining activities resumed in the Pampacancha pit in February and the period of higher stripping from March to June is progressing well, with mining of higher-grade ore now expected in the second quarter of 2023, ahead of schedule.

Sudbury: In the first quarter of 2023, Vale’s Sudbury mines produced 6,200 ounces of attributable gold, an increase of approximately 16% relative to the first quarter of 2022. As per Vale, higher production from Sudbury was driven by greater mine performance and stability in the first quarter.

Stillwater: In the first quarter of 2023, the Stillwater mines produced 2,000 ounces of attributable gold and 3,700 ounces of attributable palladium, a decrease of approximately 21% for gold and 17% for palladium relative to the first quarter of 2022. As reported by Sibanye-Stillwater Limited (“Sibanye”) on March 13, 2023, an incident occurred at the Stillwater mine during scheduled non-routine maintenance resulting in structural damage to the shaft headgear, winder house and winder rope. As a result, production from the Stillwater West mine below the 50 level was suspended for approximately five weeks, impacting production in the first quarter, but has since recommenced. 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.

Other Gold: In the first quarter of 2023, total Other Gold attributable production was 3,500 ounces, a decrease of approximately 59% relative to the first quarter of 2022, primarily due to the closure of the 777 mine in June 2022.

Voisey’s Bay: In the first quarter of 2023, the Voisey's Bay mine produced 124,000 pounds of attributable cobalt, a decrease of approximately 47% relative to the first quarter of 2022, 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 planned maintenance activities are scheduled for the second quarter of 2023. Vale reports that physical completion of the Voisey’s Bay underground mine extension was 83% at the end of the first quarter. In the second quarter of 2021, Vale achieved 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.

First Quarter Development Asset Highlights

Blackwater Project: Artemis Gold Inc. (“Artemis”) announced the approval of its BC Mines Act Permit, the final step required to allow Artemis to commence major works construction activities at the Blackwater Mine, with the expectation of an initial gold pour in the second half of 2024. In addition, Artemis announced that it issued a purchase order to Finning Canada, for the primary and ancillary mining fleet required for the initial Phase 1 of operations. Equipment deliveries to site are planned to commence late in the fourth quarter of 2023 and continue throughout the first half of 2024, in preparation for the pre-strip-mining phase. As per Artemis, the entire fleet is expected to be “shovel ready” during the second half of 2024, to meet Artemis’ operational readiness objectives and commence operations.

Copper World Complex: In January 2023, Hudbay received an approved right-of-way from the Arizona State Land Department that will allow for infrastructure such as roads, pipelines and powerlines, to connect between the properties in the company’s private land package at Copper World. Subsequent to the quarter, Hudbay announced the receipt of confirmation from the Army Corps of Engineers that Hudbay’s previous surrender of the Section 404 Clean Water Act permit for the former Rosemont project was formally accepted and revoked as requested. Clearing and grading work to prepare for the Copper World site, including the construction of roads and other facilities, continues to be underway. As per Hudbay, pre-feasibility activities for the private land Phase I of the Copper World project are well-advanced and a pre-feasibility study is expected to be released in mid-2023.

Goose Project: On April 12, 2023, Sabina Gold & Silver Corp (“Sabina”) announced that the shareholders approved the proposed acquisition by B2Gold Corp. (“B2Gold”) of all the issued and outstanding common shares of Sabina. The transaction closed April 19, 2023. Subsequent to closing, B2Gold exercised the option to acquire 33% of the stream under the Goose PMPA in exchange for a cash payment in the amount of $46 million, resulting in a gain on partial disposal of the PMPA in the amount of $5 million. B2Gold continues to advance construction of the Goose project, moving toward commencement of production in 2025 and initiating an exploration program to further define untapped potential and unlock further opportunities for growth.

Overview

Wheaton Precious Metals Corp. is a precious metal streaming company which generates its revenue primarily from the sale of precious metals (gold, silver and palladium) and cobalt. The Company is listed on the New York Stock Exchange (“NYSE”), the Toronto Stock Exchange (“TSX”) and the London Stock Exchange (“LSE”) and trades under the symbol WPM.

As of March 31, 2023, the Company has 28 long-term purchase agreements (three of which are early deposit agreements), with 22 different mining companies, for the purchase of precious metals and cobalt (“precious metal purchase agreements” or "PMPA") relating to 20 mining assets which are currently operating, 12 which are at various stages of development and 3 which have been placed in care and maintenance or have been closed, located in 13 countries. Pursuant to the PMPAs, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered which is fixed by contract, generally at or below the prevailing market price. Attributable metal production as referred to in this MD&A is the metal production to which Wheaton is entitled pursuant to the various PMPAs. During the three months ended March 31, 2023, the per ounce price paid by the Company for the metals acquired under the agreements averaged $496 for gold, $5.07 for silver, $294 for palladium and $3.32 per pound for cobalt. The primary drivers of the Company’s financial results are the volume of metal production at the various mining assets to which the PMPAs relate and the price realized by Wheaton upon the sale of the metals received. Throughout this MD&A, the production and sales volume of gold, silver and palladium are reported in ounces, while cobalt is reported in pounds.
