The Empire Mine is operated by Cliffs Natural Resources and is located in Palmer.

The mine began pellet production in 1963 and has produced more than 260 million tons of product.

Current plans as of March 2013 were to shut the mine down by the end of 2014 or the beginning of 2015, when a contract with steel-maker Arcelor Mittal expires.
