Yukon Environmental Board Approves Contentious Copper Mining Exploration Project

In a report published on October 15, 2025, the Yukon Environmental and Socio-economic Assessment Board (YESAB) has recommended approving a controversial mining exploration project proposed by Gladiator Metals in Whitehorse. The B.C.-based company is seeking to expand its existing copper belt drilling program, which has been ongoing since April 2023, by upgrading its permit from class 1 to class 3.

The proposed 5-year exploration program would involve drilling, constructing new roads and trails, and clearing land both within and outside Whitehorse city limits. YESAB has outlined 24 terms and conditions that Gladiator must follow, including wildlife monitoring, groundwater testing, and avoiding disruption to local ski trails.

The project has been met with significant opposition from Whitehorse residents, who have raised concerns about potential impacts on the environment, wildlife, and nearby neighborhoods. Over 100 comments were submitted to YESAB, with many urging the board to reject the project entirely. However, YESAB executive director Kent Bretzlaff acknowledged the board's role in allowing public participation, stating "that's the beauty of YESAB -- everyone in the territory and even outside the territory has the opportunity to be involved."

The final decision on the project now rests with the Yukon government and the Yukon Water Board, who can choose to approve, reject, or modify YESAB's recommendations.
