On June 6, Teck Resources fell 7.74% in regular trading, trading at $62.07/share, with trading volume of $126 million.

On the news front, Teck Resources significantly lowered its full-year copper production guidance due to a tailings facility malfunction at its Chilean copper mine, with the shutdown period extending beyond initial expectations. The production disruption comes amid broader weakness across the global copper mining industry, as overseas major copper producers collectively reported a 4% year-over-year and 9% quarter-over-quarter decline in first-quarter copper output, with planned completion rates reaching only 23%.

Within the Diversified Metals & Mining sector, the broader group came under heavy selling pressure. Among individual stocks, Almonty Industries down 19.71%, USA Rare Earth down 16.2%, MP Materials down 7.79%, BHP Billiton down 5.74%, and Rio Tinto down 4.06%.

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