The Tsetsaut Skii km Lax Ha Nation and the Gitxsan Huwilp Government are urging British Columbia to implement strict safeguards as the province re-evaluates the legal status of the KSM mine . This move follows a judicial ruling that invalidated a previous provincial decision regarding whether the project had sufficiently begun operations .
The BC Supreme Court's rejection of the 2024 determination
The current legal friction stems from a 2014 environmental certificate that Seabridge Gold needs to remain valid for the duration of the KSM project. While British Columbia initially ruled in 2024 that the mine had reached a "substantial start," the BC Supreme Court overturned that finding. The court cited a failure by the province to adequately consult with the Tsetsaut Skii km Lax Ha Nation , effectively resetting the clock on the project's regulatory certainty.
This clash reflects a broader shift in Canadian resource law, where "substantial start" determinations are increasingly scrutinized through the lens of Indigenous sovereignty.. The case highlights a growing trend where historical environmental assessments are no longer viewed as static documents but as living agreements that must evolve alongside the province's understanding of ancestral lands.
The Treaty Creek Valley waste facility dispute
A central point of contention is the proposed waste facility located in the Treaty Creek Valley. According to a joint release from the Tsetsaut Skii km Lax Ha and Gitxsan Huwilp Government, provincial ethnohistoric research completed in 2021 significantly expanded the government's understanding of the Tsetsaut Skii km Lax Ha territorial claims in this specific area.
Because of this updated data, the Tsetsaut Skii km Lax Ha Nation is not seeking a full repeat of the original environmental assessment, but rather a substantive role in decisions regarding the waste facility. they argue that the 2021 findings prove the project's potential effects on their territory are more significant than previously acknowledged, necessitating enforceable measures to protect the land for future generations.
Seabridge Gold's $1.4 billion investment and Indigenous contracts
The financial stakes of this reconsideration are immense. Seabridge Gold chair Rudi Fronk has noted that the company has already invested more than $1.4 billion into the KSM project. To mitigate friction and build local support, Seabridge Gold has awarded approximately $515 million in contracts to Indigenous-affiliated businesses over the last four years, as reported in the company's recent updates.
Despite these expenditures, the Gitxsan Huwilp Government withdrew its long-term support for the mine in August 2026. This reversal underscores the reality that financial contributions and business contracts do not necessarily resolve fundamental disputes over territorial rights or environmental risk management in northwestern British Columbia.
The Sept. 28 deadline and the Environmental Assessment Office's report
The timeline for resolution is now tightly defined, with a 90-day consultation period for the Tsetsaut Skii km Lax Ha Nation ending on September 28, 2026 . Following this, the provincial Environmental Assessment Office will allow Seabridge Gold to respond to the Nation's submissions before drafting a report on the substantial-start reconsideration.
However, several critical questions remain. It is unclear whether the province will grant the "practical and enforceable measures" demanded by the First Nations , or if the final decision-maker will prioritize the $1.4 billion already sunk into the project. Furthermore, the source does not clarify how the province intends to reconcile the 2021 ethnohistoric work with the original 2014 certificate without triggering a complete,multi-year environmental reassessment.
