Wheaton Precious Metals Launches Third Annual

$1 Million Future of Mining Challenge Focused on
Mine Optimization and Reducing Land Impacts

Advancing into its third year, Wheaton Precious Metals™ Corp. ("Wheaton" or the "Company") is pleased to announce the return of its Future of Mining Challenge, calling on innovators worldwide to propose solutions that optimize mining and address land impacts.

"Mining resources underpin nearly every sector, and as global demand grows, the need to produce them responsibly has never been greater," said Haytham Hodaly, President and Chief Executive Officer of Wheaton. "We believe innovation is key to improving efficiency, enhancing performance, and reducing environmental impacts. The third edition of the Future of Mining Challenge is focused on advancing solutions that optimize mining methods and reduce impacts on land. We have been encouraged by the creativity and progress of past participants and look forward to the ideas this year's challenge will bring."

For the 2026/2027 challenge, Wheaton will award US$1 million to a cleantech venture with an innovative technology that seeks to either strengthen orebody knowledge or improve extraction methods.

"It is remarkable to see how far mining has advanced, driven by the ingenuity of entrepreneurial minds committed to progressing the industry forward," said Patrick Drouin, Chief Sustainability Officer of Wheaton. "By backing bold, early-stage technologies, we hope to accelerate the next generation of solutions that improve performance and reduce environmental impact."

Wheaton invites cleantech innovators worldwide to participate in its Future of Mining Challenge and will accept expressions of interest until 11:59 p.m. (Pacific Time) on Friday, August 21, 2026. Once all expressions of interest have been reviewed, Wheaton will invite select ventures to submit a full application in September 2026. An information session will be held in early July to provide guidance for applicants and address questions on the process.

Once again, Wheaton is collaborating with the University of British Columbia's Sauder School of Business, working closely with a team that brings deep expertise in venture building and early-stage innovation support. The winner of the 2026/2027 Future of Mining Challenge will be announced in March 2027 during the PDAC Convention in Toronto, the largest mining conference in the world.

The 2025/2026 Future of Mining Challenge, announced earlier this year, focused on sustainable water management. Cetos Water was named the winner and awarded US$1 million in recognition of its innovative technology, which transforms wastewater generated by mining operations into clean, reusable water.
