Wheaton Precious Metals Corp. Announces Acquisition of Gold Stream from Capstone's Santo Domingo Project

VANCOUVER, March 25, 2021 - Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") (TSX | NYSE | LSE: WPM) is pleased to announce that its wholly-owned subsidiary, Wheaton Precious Metals International Ltd. ("Wheaton International"), has entered into a definitive Precious Metal Purchase Agreement (the "Agreement") with Capstone Mining Corp. ("Capstone") (TSX: CS) in respect to the Santo Domingo project located in the Atacama Region, Chile. Upon closing, Wheaton International will purchase 100% of the payable gold production until 285 thousand ounces ("koz") have been delivered, thereafter dropping to 67% of payable gold production for the life of the mine. Wheaton International will pay Capstone a total upfront cash consideration of US$290 million (the "Upfront Payment"), $30 million of which is payable upon closing and the remainder of which is payable during construction of the Santo Domingo project, subject to customary conditions being satisfied, including Capstone attaining sufficient financing to cover total expected capital expenditures. In addition, Wheaton will make ongoing payments for gold ounces delivered (the "Production Payment") equal to 18% of the spot gold price¹.

"Santo Domingo is an exceptional project that provides Wheaton with an additional near-term growth opportunity. The project is forecast to be a first-quartile copper producer with a long mine life, making it an ideal fit for Wheaton's existing high-quality portfolio," said Randy Smallwood, Wheaton's President and Chief Executive Officer. "We are very excited to further build our partnership with Capstone and look forward to seeing Santo Domingo developed into a top-tier copper mine."

TRANSACTION HIGHLIGHTS

• The Santo Domingo project is forecast to be a first quartile copper mine² with an 18 year mine life³.
• Attributable gold production is forecast to average 35 to 40 koz per year for the first five full years of production and 25 to 30 koz for the first ten full years³.
• Capstone expects major construction to commence in late 2021 with the first full year of production forecast for 2024.
• Subsequent to the closing of this acquisition, the addition of the Santo Domingo project will increase Wheaton's estimated Proven and Probable gold reserves by 0.51 Moz, Measured and Indicated gold resources by 0.12 Moz and Inferred gold resources by 0.03 Moz.⁴
• Exploration upside potential exists as no exploration drilling has been completed since Capstone acquired the Santo Domingo project in 2011.
• Provides Capstone with an early deposit of $30 million, which will be used to repay the funds paid by Capstone to acquire the remaining 30% of the Santo Domingo project.

TRANSACTION TERMS

• Wheaton International will be entitled to receive 100% of the payable gold production until 285 koz have been delivered, thereafter dropping to 67% of payable gold production for the life of the mine.
• Wheaton International will pay Capstone the Upfront Payment of US$290 million as follows:
• • once certain conditions have been met, Wheaton International will advance US$30 million to Capstone; and
  • the remainder of the Upfront Payment will be paid on a pro rata basis during construction (estimated to be approximately two to three years), subject to customary conditions being satisfied, including Capstone attaining sufficient financing to complete construction.
• Wheaton International will make ongoing payments for gold ounces delivered equal to 18% of the spot gold price until the value of gold delivered less the cumulative Production Payments is equal to the upfront consideration of US$290 million, at which point the Production Payment will increase to 22% of the spot gold price.
• Gold deliveries are guaranteed by Capstone and by the Santo Domingo project owner. Security over the assets of the Santo Domingo project has also been provided by the Santo Domingo project owner.
• Closing of the transaction is expected to occur shortly following announcement and is subject to the completion of certain corporate matters and customary conditions.

FINANCING THE TRANSACTION

The early deposit portion of the Upfront Payment will be made on closing, with the balance of the Upfront Payment to be paid over the construction of the Santo Domingo project. At December 31, 2020, the Company had approximately US$193 million of cash on hand and approximately US$1.8 billion of remaining capacity under the Company's US$2 billion revolving credit facility. With operating cash flow in 2020 of approximately US$765 million, the Company has ample capacity to service any additional debt resulting from this transaction, especially given the low interest rate and flexible nature of the covenants under the Company's revolving credit facility.
