Wheaton Precious Metals Announces the Acquisition of Existing Streams from Orion Mine Finance

Including the Platreef and Kudz Ze Kayah Projects, and Enters into a New Stream on the Curraghinalt Project

VANCOUVER, Nov. 15, 2023 - Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") is pleased to announce Wheaton and its wholly-owned subsidiary, Wheaton Precious Metals International Ltd. ("Wheaton International") have entered into a definitive agreement with certain entities advised by Orion Resource Partners ("Orion") to acquire existing streams in respect of Ivanhoe Mines' Platreef Project (the "Platreef Streams") and BMC Minerals' Kudz Ze Kayah Project (the "Kudz Ze Kayah Streams"). In addition, Wheaton International has entered into a new precious metals purchase agreement for a gold stream in respect of Dalradian Gold's Curraghinalt Project (the "Curraghinalt Stream").

"The acquisition of these diverse, high-quality streams fits seamlessly into our portfolio of high-margin, low-cost assets, with near-term production from Platreef significantly adding to our already robust growth profile," said Randy Smallwood, Wheaton's President and Chief Executive Officer. "This Project has been significantly de-risked given the advancement of construction and development and is forecast to deliver significant precious metals production to Wheaton, commencing next year. We are also very impressed with Ivanhoe's progress in working with the community and other stakeholders as it rapidly advances the Project towards production."

Closing of the acquisition of the Platreef, Kudz Ze Kayah and Curraghinalt Streams is subject to typical terms and conditions and anticipated to occur within the fourth quarter of 2023 or early first quarter of 2024.

Recycling locally treated water is a cost-effective and sustainable approach to securing water for the mine's production.
    • In conformance with South Africa's mining laws, the ownership structure at the Platreef Project includes a 26% interest transferred to a B-BBEE special purpose vehicle, comprised of 3% local non-managerial employees, 3% local entrepreneurs and 20% in a trust established for the benefit of the 20 communities that surround the Platreef Project area (The Bonega Communities Trust).
    • The site has secured options to use electricity generated from renewable energy and liquefied natural gas, providing a reliable source of energy with fewer carbon dioxide emissions than South Africa's coal-fired national electrical grid.
  • The Platreef Streams provide certain corporate guarantees and security over assets of the Platreef Project until certain conditions are met.

Kudz Ze Kayah Project (owned by BMC Minerals, the "Kudz Ze Kayah Streams")

• Location: Located in the northern Pelly Mountains, 115 km southeast of the Ross River in south central Yukon, Canada.

• Other Considerations:
  • Under the existing Kudz Ze Kayah Stream, BMC Minerals has a buyback option to repurchase 50% of the gold and silver streams for a period of 30 days after June 22, 2026, for $36 million.
  • The Kudz Ze Kayah Streams provide certain corporate guarantees and security over assets of the Kudz Ze Kayah Project until certain conditions are met.

Curraghinalt Project (owned by Dalradian Gold Limited, the "Curraghinalt Stream")

• Location: Located approximately 115 km west of Belfast, in Northern Ireland, United Kingdom.

  • Dalradian and certain of its subsidiaries will provide Wheaton International with corporate guarantees and certain other security over their assets.
  • Once the complete financing package has been finalized, the stream percentages will be subject to increases in the event that the existing stream held by Wheaton International is subordinated to debt.
  • Sustainability Considerations:
    • Dalradian has submitted a planning application detailing its approach to environmental protection and providing benefits to the local community.
    • The Curraghinalt mine design features a reverse osmosis water treatment plant, a dry stack tailings facility and a commitment to carbon neutrality (supported by a supply of 100% renewable electricity). Dalradian expects to hire 90% of its staff from the local area. This will be supported with an investment of £15 million towards a training program over the initial three years to assist local people to qualify for positions at the mine.

Financing the Transactions

As at September 30, 2023, the Company had approximately $834 million of cash on hand, which when combined with the liquidity provided by the available credit under the $2 billion revolving term loan and the strength of our ongoing operating cash flows, positions the Company well to fund the acquisition of the Platreef, Kudz Ze Kayah and Curraghinalt streams, as well as all outstanding commitments and known contingencies, and provides flexibility to acquire additional accretive mineral stream interests.
