Canadian miner Teck Resources Ltd. cut its forecast for annual refined zinc production on Tuesday, citing an impact on its operations from wildfires in British Columbia.

The company projected refined zinc production for 2021 to be in the range of 285,000 tonnes to 290,000 tonnes, down from a previous estimate of 290,000 tonnes to 300,000 tonnes.

Teck’s Trail Operations, located in British Columbia, were temporarily shut in August for about ten days because of poor ambient air quality resulting from wildfires. It contains one of the world’s largest fully integrated zinc and lead smelting and refining complexes, as per the company’s website.

The miner also reduced its third-quarter sales outlook for contained zinc from its Red Dog operations in northwest Alaska to 145,000 tonnes to 155,000 tonnes, down from 180,000 tonnes to 200,000 tonnes expected previously.

The latest production forecast cut comes months after Teck in July slashed its steelmaking coal output outlook by 1.9 per cent at midpoint because of the wildfires.
