Similkameen leaders say Copper Mountain mine expansion lacks consent | The Narwhal

Share Indigenous leaders from the Similkameen Valley are “deeply disappointed” by a provincial decision to approve a contentious mine expansion in their territories — emphasizing that they did not give consent for the project to move forward. On Monday, the B.C. government announced it had issued Mines Act and Environmental Management Act permits for the New Ingerbelle expansion of the Copper Mountain mine near Princeton, B.C., in smǝlqmíx (Upper and Lower Similkameen Indian Band) territory. The expansion project will see the century-old mining operation revive its old Ingerbelle open-pit gold and copper mine site near nməlqytkʷ (the Similkameen River). The expansion will extend the mine’s operation until 2047, the province said. In the province’s statement, it acknowledged that the mine is in the Upper and Lower Similkameen Indian Bands’ territories. “The permitting review process included engagement with both First Nations, along with technical review by provincial agencies to assess environmental impacts, tailings management and public safety,” it said. However, a joint statement issued Monday by leadership of both bands says that “chiefs, councillors, natural resource departments and community members of the bands did not give consent for this project to move forward.” “The smǝlqmíx and our neighbours that choose to be here forever will have to deal with the consequences long after the profits and monies have left the valley,” said the statement. “The chiefs and councils of the Upper Similkameen Indian Band and the Lower Similkameen Indian Band are deeply disappointed by the Province of British Columbia’s decision … to approve the New Ingerbelle Expansion Proposal for the Copper Mountain mine.” B.C.’s Copper Mountain mine proposes major tailings pond expansion, sparking cross-border concern The First Nations noted that participation agreements they signed with the mine earlier this month “expressly state that advance consent to New Ingerbelle was not provided.” The new participation agreements with the mine that were signed by the bands replace older ones that were signed in 2019. They include “community benefits and environmental terms related to the mine operations and protecting the Similkameen River,” “stability and certainty” for mining operations and “structured processes” between Upper and Lower Similkameen and the mine “to work together on monitoring mine operations and mitigating its environmental impacts.” The bands said they will now review the approval conditions and reasons for the decision, and “assess all available options to ensure that the waters, all living things and the lands will be taken care of.” Separating the Ingerbelle pit from the mine’s main site is the 197-kilometre-long Similkameen River. Part of the expansion project will see a bridge constructed over the river to connect the two sites. The mine’s already existing 192-metre tailings dam — roughly equivalent in height to a 58-storey building — will also be increased by an additional 87 metres, according to the province’s Environmental Assessment Office (EAO).

SUBSCRIBE The project’s approval comes less than a month after the Ministry of Mining and Critical Minerals told IndigiNews that the expansion proposal still required further consultation with the Upper and Lower Similkameen. The spokesperson also said the expansion plan had to “meet or exceed B.C.’s world-class environmental standards.” Last May, a pipe failure at the mine site resulted in 3,000 litres of mine tailings seeping into an area beside the Similkameen River. The B.C. Ministry of Environment and Parks told IndigiNews that it’s unknown if the mine water entered the river or was absorbed into the ground. In 2024, the provincial Ministry of Environment and Climate Change Strategy issued six fines to Copper Mountain mine totalling $105,348.  B.C. is home to ‘high-risk’ toxic mine waste sites. Here are 5 you need to know about The string of offences, which occurred between 2019 and 2022, all relate to the mine’s unauthorized seepage and discharge of mine water from its tailings pond into the surrounding waterways of the Similkameen River and Wolfe Creek, which both flow through the mine’s area of operation. In 2021, the mine at one point exceeded the legal limit of copper waste discharged from its tailings pond into Wolfe Creek by more than 4,500 per cent. Two years ago, one Lower Similkameen member spoke of a time where you could drink the water from Wolfe Creek, which is a tributary of the Similkameen River. Despite a series of mine contamination events into the creek, a senior representative for the Copper Mountain mine told the community that she would still drink the water. Wolfe Creek is downstream from the Copper Mountain mine’s tailings dam, and has experienced several contamination events. Despite this, a senior representative for the mine said she would still drink the water. Photo: Aaron Hemens / IndigiNews In January, a province-wide council of outdoor recreationists declared the Similkameen River among the province’s most endangered rivers – citing the mine’s expansion as the main threat to the waterway. Last November, y̓ilmixʷm (Chief) kalʔlùpaɋʹn Keith Crow of Lower Similkameen told regional officials that leaders were failing the Similkameen River, which “had been black for the last month” due to poor water quality.  Lower Similkameen Elder Rob Edward listed the mine as one of the reasons for the river’s decline. He noted that he hasn’t been able to fish out of the Similkameen River since 1982.  In 2022, Crow told IndigiNews that the Similkameen River is the lifeblood of the valley. “If we lose that, we lose our identity. We lose who we are,” he said. How our journalism makes a difference Here at The Narwhal, we do journalism differently.

Judge upholds BLM approval of Rhyolite Ridge lithium mine - ICT

U.S. District Judge Cristina Silva ruled the Interior Department took a sufficiently “hard look” at the impacts of the mine on Tiehm’s buckwheat and Fish Lake Valley tui chub and “reasonably found” that the project would “not result in unnecessary or undue degradation of Tiehm’s buckwheat.”
