WESTERN PROVIDES CASINO PROJECT UPDATE

VANCOUVER, B.C. Western Copper and Gold Corporation ( “Western” or the “ Company”) (TSX : WRN ;

NYSE A merican: WRN ) is pleased to provide an update on Casino Project activities. The Company

completed a number of important permitting activities in 2018 and plans to continue advancing the Casino

Project in 2019.

PERMITTING & ENGINEERING

In 2018, t he Company continued to work towards preparing its environmental assessment application,

known as the Environmental and Socio- Economic ( “ESE”) Statement for submission to the Yukon

Environmental and Socio-economic Assessment Board (“YESAB”). Most of the Company’s activities were

focused on the Best Available Tailings Technology (“BATT”) Study, but Western also completed a number

of First Nation Traditional Land Use Studies, continued its baseline data collection program, and conducted

a number of smaller environmental studies.

The results of the BATT Study were announced on November 5, 2018. The BATT Study was an 18-month

process that will become an essential component of the ESE Statement for the Casino Project. During this

process, the participants selected the option for disposal of tailings and mine waste considered to be the

Best Available Technology for the Casino Project, taking into account environmental, technical, economic,

and social considerations.

Traditional Land Use Studies have now been completed for all First Nations identified by YESAB as being

potentially impacted by the Casino Project. The se studies took place over the past two years and are

central to the assessment of effects of the Casino Project and are therefore a critical step in the completion

of the ESE Statement.

The Company has initiated engineering activities to incorporate the outcomes of the BATT Study into the

tailings management facility design. As a result of the additional engineering work and other considerations,

the Company has informed YESAB that it will be deferring the submission of its ESE Statement.

INFRASTRUCTURE

In 2017, the Federal and Yukon Governments announced commitments to fund the upgrade of 82 km of

the existing access road to standards required for the Casino Project, as well as to fund 30% of the

additional 126 km of new access road to the Casino site. Recent statements from the Yukon Government

indicate that they expect to commence work on the upgrade of the existing access road in 2019, beginning

with a bypass around the town of Carmacks. The bypass will minimize the amount of mine traffic travelling

through Carmacks.

“The work that the team has accomplished in 2018 cannot be overstated. The Traditional Land Use and

BATT Studies were long lead-time studies that were essential to complete before finalizing our ESE

Statement.” said Paul West-Sells, President & CEO, “The Casino Project is now considerably de-risked

and we will continue our efforts to move the project forward in 2019.”
