VANCOUVER, BC, Nov. 6, 2025/CNW/ - Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") is pleased to announce that its wholly-owned subsidiary, Wheaton Precious Metals International Ltd. ("WPMI") has entered into a definitive Precious Metals Purchase Agreement (the "Gold Stream") with Waterton Gold Corp., a subsidiary of Waterton Gold LP ("Waterton Gold") in respect of the Spring Valley Project located in Nevada, USA(the "Project" or "Spring Valley"), which is owned by Waterton Gold's wholly owned subsidiary, Solidus Resources, LLC ("Solidus").

"Wheaton is delighted to support one of our existing partners, Waterton, as they advance the Spring Valley Project, a large scale gold development in Nevada," said Randy Smallwood, Chief Executive Officer of Wheaton Precious Metals. "With its strong geological profile, strategic location, and proven leadership, already demonstrated through our partnership at Mineral Park, Spring Valleyaligns perfectly with our commitment to investing in high-quality, value-accretive assets."

"The addition of Spring Valleyadds another high-quality, low-cost mine in a tier-one jurisdiction to Wheaton's portfolio," added Haytham Hodaly, President of Wheaton Precious Metals. "The project meets all the criteria of our rigorous due diligence process, from scale to margins to exploration upside to quality of the management team. We're excited to deepen our relationship with Waterton as they unlock the full potential of this asset."

"We are pleased to again partner with Wheaton," said Isser Elishis, Executive Chairman of Waterton Gold. "With Wheaton's commitment, the project is now fully funded, backed by $1.3 billionin committed capital. Early site works are already underway as we prepare to commence full construction in 2026 and achieve first gold production in the first half of 2028. This milestone underscores the strength of the project and advances the development of Nevada'snext major low-cost heap-leach gold mine, creating meaningful long-term value for all stakeholders."

Transaction Details (All values in US$ unless otherwise noted)

Upfront Consideration:WPMI will pay Waterton Gold total upfront cash consideration of $670 million(the "Deposit"), to be paid in installments as various conditions are satisfied. Streamed Metal:Under the Gold Stream, WPMI will purchase 8% of the payable gold until 300,000 ounces have been delivered, after which the Company will purchase 6% of the payable gold for the life of the mine. Production Profile1:Attributable production is forecast to average approximately 29 thousand ounces ("Koz") of gold per year for the first five years of production, and over 25 Koz of gold per year for the first ten years, with first production expected in 2028. Spring Valleyhas a mine life of 10 years based on reserves at an $1,800/oz gold price. Production Payments:WPMI will make ongoing payments for the gold ounces delivered equal to 20% of the spot price of gold until the uncredited deposit has been fully reduced, and 22% of the spot price of gold thereafter. Incremental Reserves and Resources1: The addition of Spring Valleywill increase Wheaton's total estimated Probable Mineral gold reserves by 0.31 Moz, Indicated Mineral gold resources by 0.06 Moz and Inferred gold resources by 0.05 Moz. Other Considerations:

Financing the Transactions As at June 30, 2025, the Company had approximately $1 billionof cash on hand. Wheaton believes that, when combined with the liquidity available under its $2 billionrevolving term loan coupled with its $500 millionaccordion and ongoing operating cash flows, it is well positioned to fund the acquisition of the Gold Stream. This financial position supports outstanding commitments and known contingencies, while providing flexibility to pursue additional accretive mineral stream interests.
