Lawsuit Filed Against Vancouver Company for Alleged Negligence in Yukon Gold Mine Disaster

📅 Today

PricewaterhouseCoopers has filed a lawsuit against JDS Energy and Mining Inc. in connection with a catastrophic failure at the Eagle Gold Mine in Yukon, claiming negligence in engineering practices that led to a significant environmental disaster.

In a significant legal development, the receiver of a defunct gold mine in Yukon is taking action against a Vancouver-based mining engineering firm, alleging negligence that contributed to a catastrophic storage site failure in 2024. The lawsuit, lodged by PricewaterhouseCoopers in the British Columbia Supreme Court on June 19, targets JDS Energy and Mining Inc., which is accused of making critical errors during its long-term provision of construction and engineering services to the Eagle Gold Mine. The incident in question occurred on June 24, 2024, when a heap leach pad at the mine near Mayo, Yukon, failed, resulting in the release of approximately two million tonnes of cyanide-laden ore into the surrounding environment, including areas that support local fish populations. According to the civil claim, JDS Energy and Mining had been involved with Victoria Gold, the mine's operator, for over a decade, offering various services that included consultations, feasibility studies, and construction management related to the ore storage facility. The lawsuit alleges that JDS failed to properly advise Victoria Gold on essential practices, such as ensuring adequate fluid drainage from the heap leach pad. This oversight reportedly led to the formation of weak layers within the storage structure, ultimately causing the catastrophic slide. As of now, representatives from JDS Energy and Mining have not responded to inquiries regarding the lawsuit, nor have they filed a legal response to the claims made against them. The legal action also highlights that JDS neglected to address the risks associated with year-round ore stacking in the cold climate of Yukon. Earlier feasibility studies had cautioned against this practice, recommending that ore stacking be limited to 250 days each year during the warmer months to prevent the formation of frozen patches within the heap. Furthermore, these studies had suggested that leaching solutions be heated and irrigation lines buried to mitigate risks. However, the lawsuit claims that year-round stacking was adopted following its endorsement in a 2022 Technical Report, which JDS was involved in preparing. The ramifications of this lawsuit could be significant, not only for the parties involved but also for the broader mining industry in Yukon, raising questions about engineering practices and environmental safeguards in gold mining operations.
