Corporate Updates

WESTERN COPPER AND GOLD ANNOUNCES

SUBMISSION OF ESE STATEMENT

VANCOUVER, BC

,

Oct. 6, 2025

/CNW/ - Western Copper and Gold Corporation ("Western" or the "Company") (TSX: WRN)

(NYSE American: WRN) is pleased to announce the submission of its Environmental and Socio-economic Effects Statement

("ESE Statement") for the proposed

Casino

Project ("

Casino

" or the "Project") to the Yukon Environmental and Socio-economic

Assessment Board ("YESAB").

The submission is an important step in the Panel Review process under the

Yukon Environmental and Socio-economic

Assessment Act

("YESAA"), representing a significant positive step in the permitting process for

Casino

.

The ESE Statement details the assessment of potential Project-related and cumulative environmental and socio-economic

effects for Valued Environmental and Socio-economic Components ("VESECs"). With the implementation of a comprehensive

suite of environmental management measures, including mitigation measures, management and monitoring plans, and an

adaptive management approach, Project-related residual effects and any cumulative residual effects were assessed to be not

significant across all VESECs.

Shena Shaw

, Vice President of Environmental & Community Affairs, commented:

"Our submission represents years of careful planning and collaboration and demonstrates that

Casino

can be advanced in an

environmentally and socially responsible manner, with generational benefits for all Yukoners.

We remain steadfast in our commitment to ongoing collaboration with affected First Nations, local communities, and the

broader public – an approach that has been foundational to reaching today's milestone."

Sandeep Singh

, President & Chief Executive Officer, commented:

"Submission of the ESE Statement is a major achievement. I commend our team and our external consultants for their

diligence in completing this extensive and critical body of work.

We enter this next phase of assessment with a tremendous amount of scientific research underpinning the Project, the

highest environmental and socio-economic standards, and an unwavering commitment to responsible resource development

in the

Yukon

. We commit to continuing that rigorous analysis and deepening our collaboration with all Yukoners as we

advance through the regulatory process.

Casino

is positioned to play a pivotal role in improving the legacy of mining in the

Yukon

, enabling benefits that can serve the

territory for decades, and becoming a pillar of economic growth and prosperity in the North."

Next Steps

After a short review period, YESAB will publish the ESE Statement to its online registry. The next step will involve a sufficiency

check by YESAB's Executive Committee to confirm that the ESE Statement meets the ESE Statement Guidelines, as well as

other preparatory steps by YESAB to formally establish the Panel of the Board, which will conduct a comprehensive

assessment of the Project.
