08:04 AM EDT, 06/16/2025 (MT Newswires) -- Western Copper and Gold Corporation ( WRN ) announced Monday an extension and revision of its Investor Rights Agreement with Rio Tinto Canada Inc.

As part of a revised IRA, Monday's statement noted, Rio Tinto will continue to hold a seat on the Casino Technical and Sustainability Committee, along with one representative from Mitsubishi Materials and three from Western, to promote ongoing technical collaboration. Rio Tinto's existing standstill and trading restrictions, along with certain other obligations, will remain in effect, while the previous board observer right and potential board seat rights have been extinguished. The revised IRA will expire on the earlier of November 30, 2026, or when Rio Tinto's ownership falls below 5%.

"We are pleased to maintain Rio Tinto's presence on the TSC as it has been mutually beneficial to both Western and Rio Tinto," said Sandeep Singh, President and CEO. "Rio Tinto remains a supportive shareholder, and we value the expertise they bring to bear on the project. It did make sense, however, to refine some of the previous rights, especially as we have taken steps to enhance our own independent board of directors over time."

WRN was up $0.03 at $1.85 on Friday.
