Tilden Mine is located in Michigan’s Upper Peninsula approximately five miles south of Ishpeming. Cliffs became sole owner of the mine in 2017.
Tilden’s operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills, magnetite separation and floatation to produce hematite and magnetite concentrates that are then supplied to the on-site pellet plant. Pellets are transported by LS&I rail to port at Marquette.
Tilden Mine operates an Environmental Management System in compliance with ISO 14011:2015 requirements.
