A layoff that began in late October for 32 employees at a sand mine in Bloomer will continue indefinitely.

Iron Mountain Trap Rock Company recently informed the state Department of Workforce Development the layoff that was expected to be less than six months is ongoing and its end is unknown.

"While we hope that this extended layoff will be temporary, at this time we do not know with reasonable certainty when the layoff will end," according to a letter from Julia Shields, senior vice president of human resources for facility owner, Fred Weber Inc.

Iron Mountain Trap Rock Company operated the Bloomer site at 19952 Highway DD to provide sand for Superior Silica Sand. But ongoing discussions between the two companies have indicated that Superior will not be requiring Iron Mountain's services in the near future, according to the letter, and the layoff will continue until that changes.
