Molycorp Announces Delay in Filing 10-K and Postponement of Fourth Quarter and Full Year 2012 Earnings Call

GREENWOOD VILLAGE, Colo., February 28, 2013 /FSC/ - Molycorp, Inc (NYSE: MCP), today announced that it will require an extension of time to file its Annual Report on Form 10-K. The Form 10-K would otherwise have been required to be filed no later than March 1, 2013. The Company noted that the filing delay is necessary for it to determine the amount of a non-cash goodwill impairment charge, which it estimates will be substantial, to be recorded for the fourth quarter and reflected on its full year 2012 financial statements.

The Company expects to file the Form 10-K by March 15 and will reschedule its fourth quarter and full year 2012 earnings conference call to coincide with the filing of its 10-K.
