Antamina

Teck Resources announced that a major expansion at the Antamina mine in Peru is expected to increase ore throughput by approximately 38% to 130,000 tonnes per day, and annual production of copper and zinc by approximately 30% on completion in late 2011. Teck owns a 22.5% interest in Compania Minera Antamina, which owns the mine.

During the quarter reported as a result of higher mill throughput, copper production increased by 7% to 79,000 tonnes compared with 74,100 tonnes a year ago. Zinc production in the quarter increased by 19% over last year to 92,400 tonnes due to processing a greater amount of copper-zinc ores, partly offset by lower ore grades due to mine sequencing.

For the quarter ended reported copper production in the fourth quarter was slightly lower than a year ago at 87,900 tonnes, while zinc production almost doubled to 83,000 tonnes due mainly to the processing of a significantly greater amount of copper-zinc ores in the quarter compared with last year.
