Molycorp Announces New Rare Earth Complex is Operational and Ramping up Toward Full-Scale Production

GREENWOOD VILLAGE, CO, January 10, 2013 /FSC/ - Molycorp, Inc (NYSE: MCP, "Company")today announced that all key production components of its new state-of-the-art rare earth manufacturing complex in Mountain Pass, California are up and operational and that the facility has begun ramping up to its full-scale "Phase 1" run rate.

The Company expects that with an orderly ramp up of production it will reach or exceed its Phase 1 run rate of 19,050 metric tons per year (mt/year) of rare earth oxide equivalent (REO) by mid-year.

"Mountain Pass is the world's largest, most technologically advanced and most environmentally responsible rare earth manufacturing complex ever built, and reaching operational status is a historic event. I am very proud of the work of the entire Molycorp team in achieving this extraordinary milestone," said Molycorp President and Chief Executive Officer Constantine Karayannopoulos.

The Mountain Pass complex is designed to be able to allow for expanded production to a "Phase 2" rate of as much as 40,000 mt/year of rare earth oxide equivalent. However, the Company stated that, while most of the equipment necessary to complete Project Phoenix Phase 2 is already on site, the decision to complete Phase 2 construction and start-up will not be made until market demand, product pricing, capital availability, and financial returns justify additional increases in production beyond Phase 1.

Company officials said that controlling capital and operating costs continues to be a top priority. With the combination of the new Phase 1 ramp-up schedule and current rare earth pricing environment, the Company anticipates lower than expected revenue and cash flow for 2013, and is evaluating its capital needs for 2013.

Factors that may cause actual results to differ materially from expected results described in forward-looking statements include, but are not limited to: the potential need to secure additional capital to implement Molycorp's business plans, and Molycorp's ability to successfully secure any such capital; Molycorp's ability to complete its planned capital projects, such as its modernization and expansion efforts, including the achievement of an annual production rate of 19,050 metric tons at the Mountain Pass rare earth mine and processing facility, which management refers to as Project Phoenix Phase 1, and the second phase capacity expansion plan, which management refers to as Project Phoenix Phase 2, and reach full planned production rates for REO and other planned downstream products, in each case within the projected time frame; the success of Molycorp's cost mitigation efforts in connection with Project Phoenix, which if unsuccessful, might cause its costs to exceed budget; the final costs of Molycorp's planned capital projects, such as Project Phoenix Phase 1 and Project Phoenix Phase 2, which may differ from estimated costs; Molycorp's ability to successfully integrate Neo Material Technologies, Inc. (now Molycorp Canada), with its operations; Molycorp's ability to achieve fully the strategic and financial objectives related to the acquisition of Molycorp Canada, including the acquisition's impact on Molycorp's financial condition and results of operations; and unexpected costs or liabilities that may arise from the acquisition, ownership or operation of Molycorp Canada.
