Western Copper and Gold and Mitsubishi Materials Strengthen Strategic Partnership

Vancouver, B.C. Western Copper and Gold Corporation ("Western" or the "Company") (TSX: WRN; NYSE American: WRN) is pleased to announce a further strengthening of its strategic partnership with Mitsubishi Materials Corporation ("Mitsubishi Materials").

Further to its news release dated June 4, 2026, Western has entered into an amended and restated investor rights agreement with Mitsubishi Materials, most notably extending the rights and obligations thereunder until November 30, 2028, subject to Mitsubishi Materials acquiring 1.2 million common shares of the Company through open market purchases. These purchases will be non-dilutive to existing shareholders, as no new shares will be issued by the Company. Upon completion, Mitsubishi Materials' ownership in Western will return to approximately 5%.

"Mitsubishi Materials continues to demonstrate their long-term conviction in Western and the Casino Project," said Sandeep Singh, President & CEO. "We greatly value their involvement and feel it is mutually beneficial to extend the relationship."
