May 5, 2009 Cliffs Natural Resources Inc, announced the current shutdown at its Northshore Mine will be extended through early July, 2009. The Northshore Mine is located in Silver Bay and initiated a six-week shutdown in April, reducing production to approximately 3.7 million tons in 2009. The announced operations curtailment will reduce 2009 projected pellet production to approximately 3.2 million tons.
October 28, 2008 Cliffs Natural Resources has initiated production curtailments at two of its six North American Iron Ore mines. Cliffs indicated that the curtailments were necessary to bring production levels in line with demand. Cliffs will temporarily idle two small pellet furnaces at Northshore Mining and one small pellet furnace at United Taconite. Both locations are in Minnesota, USA. On a combined basis, the three furnaces have monthly pellet production capacity of approximately 300,000 tons.
