LOGAN LAKE, B.C. – Mining News Service – Labour pressure on Canada’s largest copper mine has widened after the B.C. Federation of Labour asked affiliated workers not to handle products originating from Teck Resources’ Highland Valley Copper operation.
More than 1,200 members of United Steelworkers Local 7619 have been on strike since Oct. 24. The federation’s so-called hot declaration took effect Nov. 6 and covers copper concentrate, molybdenum concentrate and other mineral products and byproducts from the mine, including material in storage or transit.
The direction asks affiliated union members to refrain from loading, unloading, storing, transporting, shipping, processing or otherwise handling identified product, subject to their collective agreements and federation policy. Its practical effect will depend on where product moves and which workers and agreements apply.
Union and company differ on the path to a deal
The union says the dispute involves wages, pensions, staffing, worker retention and safety. Those claims come from the union and labour federation.
Before the strike began, Teck said it was committed to a collective agreement that is fair and reasonable for employees and supports the operation’s continuing viability. The company said contingency plans were in place for safety and environmental management during labour action.
No newer Teck response to the hot declaration was identified on the company’s public news-release page by the research cutoff. The absence of a public release does not establish the status of bargaining, production or shipments.
National copper supply and a live construction project
Highland Valley Copper is central to Canada’s domestic copper output. Teck’s 2026 guidance calls for 115,000 to 135,000 tonnes of copper from the operation, with the company saying in its third-quarter update that it expected production toward the high end of that range before the strike’s effects were known.
The dispute also overlaps with a major brownfield construction program. Teck began building the $2.1-billion to $2.4-billion mine-life extension in 2025. The project is intended to extend operations from 2028 through 2046 and support average production of 132,000 tonnes of copper a year over the extended mine life.
Those production, cost and schedule figures are company guidance, not guaranteed outcomes. The immediate questions are whether the hot declaration changes product movement, whether bargaining resumes, and whether the labour disruption affects current output or extension work. No settlement timetable has been announced.
META: B.C. unions are being asked not to handle Highland Valley Copper products as a strike by more than 1,200 Steelworkers continues.
