Oct 8 (Reuters) -

Canadian miner Teck Resources Limited ( TECK ) on

Wednesday cut its copper production forecast at its flagship

Quebrada Blanca (QB) mine in Chile through 2028, following a

company-wide operations

review

and its merger with Anglo American.

Its 2026 copper output guidance was now 200,000-235,000

metric tons, from 280,000 to 310,000 tons previously. Teck also

nearly halved molybdenum production guidance to 2,800 to 3,400

tons from 6,400 to 7,600 tons.

Copper production is now expected at 240,000-275,000 tons in

2027 and 220,000-255,000 tons in 2028, down from previous

forecasts of 280,000-310,000 tons and 270,000-300,000 tons

respectively.

The guidance cuts were mostly due to a tailings issue

that relates to the disposal of mine waste, which weighed on the

company's shares after it missed production forecasts.

In September, Teck said it had agreed to merge with

London-listed Anglo American in a $53 billion deal.

Anglo on Wednesday said that while the outcome of Teck's

review was not known at the time, it was broadly consistent with

its independent due diligence and analysis.
