According to the news platform “Madan Nameh“, approximately 1,200 workers at the Highland Valley Copper mine in British Columbia began their strike on October 24. These workers, members of the United Steelworkers Local 7619 union, received strike authorization after the previous contract ended on September 30 and no new agreement was reached.
Reports indicate that workers overwhelmingly supported the work stoppage in a strike vote. Disputes between the union and Teck Resources primarily revolve around wages, benefits, retirement plans, and the number of personnel at the mine.
Teck Resources has announced that mining operations have not fully stopped but are continuing at a reduced capacity. The company has yet to provide an accurate estimate of production losses caused by the strike and states that the impact depends on the duration of the strike.
The significance of this strike lies in the fact that Highland Valley Copper is one of North America’s most important copper mines. In 2025, this mine produced approximately 127,100 tons of copper, which accounted for about 28% of Teck Resources’ total copper output that year.
At a time when the global copper market is facing concerns regarding supply growth and disruptions at some major mines, the production reduction at Highland Valley could add further pressure on the market.
Moreover, these developments gain additional importance ahead of the completion of the merger between Teck Resources and Anglo American. The new company resulting from this merger is set to become one of the world’s major copper producers, with Highland Valley Copper being one of its key copper assets.
Currently, it is unclear when negotiations between the union and Teck Resources will resume and how long the strike will last. This will determine the extent of the event’s impact on the company’s annual copper production and the global supply of this metal.
