Stimson Lumber will close its mill in Bonner, Mont., according to a report in the Missoulian (Missoula County, Mont.) newspaper.

The mill will close indefinitely due to the effects of a downturn in the North American housing market and lower lumber demand, according to the report.

The mill employs around 100 workers, who were given 60-day notices this week as the plant prepares for closure. Additionally, the company plans to shut down operations at a Coeur d’Alene, Idaho, plant, which employs about 60 people.

Based on Portland, Ore., Stimson Lumber has assets and operations in Idaho, Montana, Oregon and Washington.
