On June 3, Teck Resources fell 5.07% in regular trading, trading at $66.96/share, with trading volume of $135 million.

On the news front, Teck Resources significantly lowered its full-year copper production guidance due to a tailings facility failure at its Chilean copper mine, which extended the shutdown period. The production disruption comes amid broader industry weakness, as 20 major overseas copper producers reported Q1 aggregate copper output declining 4% year-over-year and 9% quarter-over-quarter, with plan completion rates reaching only 23%. Multiple mainstream copper miners have collectively revised production targets downward.

Within the Diversified Metals & Mining sector, the overall sector traded lower. Among individual stocks, USA Rare Earth Inc. down 7.83%, MP Materials Corp. down 5.02%, HudBay Minerals down 3.98%, Rio Tinto PLC down 3.11%, BHP Billiton down 2.33%.

Teck Resources is Canada's largest diversified mining company and a major global producer of copper, steelmaking coal, zinc, and molybdenum, with mine interests in Canada, the United States, Chile, and Peru.
