Molycorp Announces Mechanical Completion and the Start of Commissioning of Both the Chloralkali Plant and the Final Unit of Multi-Stage Cracking at Mountain Pass

Greenwood Village, CO (8 a.m. Eastern, Wednesday, Oct. 2, 2013) - Molycorp, Inc.
(NYSE: MCP) ("Molycorp" or the "Company") today announced that the chloralkali
plant at Mountain Pass, California, is now mechanically complete and that full-
scale commissioning operations have commenced.

The chloralkali plant will recycle wastewater and produce hydrochloric acid and
caustic soda used as part of the rare earth separations process.  Company
officials said that once fully operational and optimized, the chloralkali plant
is expected to help the facility achieve its cash production cost targets,
which the Company believes will make it competitive with the lowest cost
producers globally.

The Company also confirmed that the final unit of its multi-stage cracking
plant at Mountain Pass is now mechanically complete and is being
commissioned. The unit is part of a multi-stage chemical process designed to
increase the facility's current rare earth recovery rates, increase production
throughput, and contribute to lower unit production costs.

"These are the last major construction activities of Project Phoenix, the re-
build of Mountain Pass, and we expect these units to be commissioned and enter
into production in the fourth quarter of 2013," said Constantine
Karayannopoulos, President and Chief Executive Officer of Molycorp.  "Bringing
these units online will help us focus on increasing production while continuing
to reduce our production costs."
