WESTERN COPPER AND GOLD UPDATES SCHEDULE OF ENVIRONMENTAL AND SOCIO-ECONOMIC EFFECTS STATEMENT SUBMISSION PROCESS FOR CASINO

western copper and gold corporation ("Western" or the "Company") (TSX: WRN) (NYSE American: WRN) is pleased to provide an update on its Environmental and Socio-economic Effects Statement ("ESE Statement") submission for the Casino Project (the "Project").

The ESE Statement incorporates extensive technical work, including environmental and socio-economic baselines studies and assessments. Western is pleased with the progress to date and the level of consultation achieved thus far with First Nations and communities. The feedback from this engagement is making the Project stronger, and we look forward to continuing and intensifying these efforts during the assessment process. The Company expects to deliver its ESE Statement to the Yukon Environmental and Socio-economic Assessment Board ("YESAB") before the end of October.

"The Western team and our external consultants have been working diligently on the Project ESE Statement" said Sandeep Singh , President & CEO. "There is an incredible amount of work that has already gone into the Project. We are now in the final stages of compiling and refining this body of work into our submission.

The Company is the first to undertake a Panel Review in the Yukon , the highest level of rigor of any project assessed in the territory. We welcome that oversight and believe, more than ever, that the Project can be advanced sustainably and for the benefit of all Yukoners.

As one of Canada's largest and most advanced critical minerals projects, we are uniquely positioned to benefit from Yukon and Federal priorities around resource security, Arctic sovereignty, and nation-strengthening infrastructure."

western copper and gold corporation ("Western" or the "Company") (TSX: WRN) (NYSE American: WRN) is pleased to announce an extension and revision of its Investor Rights Agreement ("IRA") with Rio Tinto Canada Inc. ("Rio Tinto").

As part of a revised IRA, Rio Tinto will continue to hold a seat on the Casino Technical and Sustainability Committee ("TSC"), 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."
