A British Columbia Supreme Court judge has dismissed a legal challenge seeking to require a provincial environmental assessment for the proposed open-pit Record Ridge magnesium mine near Rossland, B.C., clearing a major hurdle for the project to proceed.
The lawsuit, brought by residents represented by the Save Record Ridge Action Committee Society (SRRACS) and the Indigenous nation of the Sinixt Confederacy, challenged a 2025 decision by B.C.’s Environmental Assessment Office (EAO) that determined the open-pit mine would not require an environmental assessment certificate.
The project, owned by Calgary-based West High Yield Resources, is proposed for Record Ridge, approximately seven kilometres west-southwest of Rossland, a community of about 4,300 residents. The company has been advancing plans for the mine since about 2005.
In an August 2025 report, the EAO concluded that the project’s proposed annual ore production capacity of 63,500 tonnes falls below the threshold that automatically triggers a provincial environmental assessment. Under B.C.’s Reviewable Projects Regulation, new mineral mines with production capacities of 75,000 tonnes per year or greater are subject to mandatory review.

Opponents argued that exempting the project from the environmental assessment process would limit scrutiny of potential impacts on public health, water quality, wildlife habitat and the local tourism economy. Court documents cited concerns about sensitive ecosystems in the area, including habitat for the threatened mountain holly fern, as well as risks related to asbestos, acid rock drainage and community consultation.
The petitioners also argued that the project could undermine Rossland’s reputation as a sustainable tourism destination and negatively affect the region’s outdoor recreation sector.
In a June 2026 ruling, Justice Gordon Weatherill upheld the EAO’s determination, finding that the agency’s decision-making process was reasonable and supported by the evidence.
“The CEAO’s determination met the hallmarks of an internally coherent and rational chain of analysis and was justified in relation to the facts and law that constrained the CEAO,” Weatherill wrote in his decision.
The ruling effectively confirms that the project can continue through other regulatory approval processes without obtaining an environmental assessment certificate, unless future changes to the mine’s design or production capacity trigger additional review requirements.
