According to employees and signs on the doors, the sporting goods store's final day of operation at the Schuylkill Mall will be December 31, 2017.
Dunham's was one of the final 3 tenants still in operation within the main mall property.
Still open are the Pearl Movie Theater and a Labor and Industry Office for Mine Safety.
Tenants of the mall were notified by the new owners, Northpoint Development, earlier this year to close their properties by year's end. Dunham's had made no announcements prior on a closing date.
