Item 7.01. Regulation FD Disclosure.

Molycorp, Inc. is filing herewith as Exhibit 99.1 a slide presentation entitled “Environmental Technology Innovation: Key to Sustainable Rare Earth Development,” which is incorporated herein by reference. The slide presentation shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into a filing under the Securities Act of 1933 (the “Securities Act”) or the Exchange Act, except as shall be set forth by specific reference in such filing.

The slide presentation references the discovery of a heavy rare earth ore deposit. Molycorp must do extensive test drilling to determine the quantity and quality of the deposit. Accordingly, there can be no assurance as to the quantity or quality of such rare earth deposit or that such deposit will become proven or probable reserves.

Key Development Principles Molycorp's Key Development Principles: Environmentally superior processes Independent markets for cerium & lanthanum Globally superior economics These principles have guided product research, process development and engineering for Project Phoenix, the Mountain Pass rebuild 3

Advanced Salt Recycle Process Allows us to convert waste salts into reagents for RE processing Virtually eliminates wastewater discharge Solidified Permanent Tailings Disposal Paste tailings to be deposited on advanced liner system Provides for permanent tailings disposal in a licensed rad waste disposal area Combined Heat and Power Plant Utilizes natural gas and eliminates use of fuel oil and other low-efficiency, high-polluting fuels Provides significant reduction in power costs Significantly reduces overall environmental footprint of project High efficiency processing Maximizes rare earth recovery per ton of ore Minimizes reagent and power consumption Environmental Technology Breakthroughs 4

Mountain Pass Closed Loop Process Molycorp Confidential Information 5 Mine Salt Recovery Unit Mill Extraction/ Purification REE Separation Finished Products Paste Tailings Impoundment Salt Purification Chloralkali Products Water Salt Tailings Impurities Pure NaCl Water HCl/NaOH Waste brine is purified and converted to reagents which are recycled into the process.

(CHART) China How Technology Innovation Drives Our Competitiveness 4,5 Current Average Rare Earth Oxide Production Cost (per kg) 2,3 Cost-advantaged processing drives significant commercial advantage: Greater power reliability and efficiency via onsite natural gas co-generation On-site reagent production and acid recycling Process technology breakthroughs Infrastructure Molycorp maintains its cost structure as the lowest in the world and may benefit from synergies in the Phase 2 expansion process Competitors face increasing costs: Chinese focus on reducing environmental degradation has increased cost structure In December 2010, Lynas revised upward its estimated costs for the Mt. Weld project 4 In March 2011, Lynas revised upward again its estimated costs for the Mt. Weld project 5 1 $5.64 (3/2010) $7.00 (12/2010) 1 Based on SRK production costs as of April 28, 2010 2 IMCOA 3 Wang Guozhen, the former VP of China Nonferrous Engineering and Research Institute, indicated that China's production costs may double as a result of ongoing environmental reforms. Base cost numbers were not quantified. (Metal-Pages.com, Jan. 7, 2011) 4 Based on Lynas presentation as of 12/7/2010 5 Lynas statement as reported in Metal-Pages.com, March 23, 2011. 6

Our Approach to the HREE Issue Increase HREE production via recycling Magnets Phosphors Increase efficient use of HREEs in key applications Boulder Wind Power's technology DOE projects with Ames Lab Utilize new cracking technology Allows full utilization of all minerals in the Mtn. Pass ore body Allows use of mineral concentrates from other sources 7 Identify and develop new HREE resources

Resource Screening Requirements Adequate ore grade (2% min.) REE distribution skewed toward HREEs Path to environmentally superior processing 8 We Apply Our Development Principles to HREE Exploration

Molycorp is tapping into its 57 years of exploration experience and data Now Focusing on 4 New HREE Prospects All have high (> 4%) REO ore grades and very significant HREE content All have mineralizations that can be processed by Molycorp None of these have been discussed in the media or are associated with publicly traded rare earth mining companies 9 New HREE Resources

One of These Four Deposits is in the U.S. We own all necessary mining claims Within easy access to Mountain Pass High ore grade and high HREE content Preliminary results from surface sampling indicate: 1.6% Tb 0.5% Dy 0.8% Eu 3.5% Sm Surface occurrence extends > 10,000 feet Can be readily processed at our facility 2% Y 21% Nd 5% Pr 10 New HREE Resources

New HREE Resources Next Steps Complete instrument surveys Conduct drilling program Estimate the extent of mineralization and define the "ore body" Conduct hydrometallurgical analysis Develop mine plan Secure mine permits Molycorp Confidential Information 11

Summary Mountain Pass Rebuild Has Been Driven By Our Key Development Principles Environmentally superior processes Independent markets for cerium & lanthanum Globally superior economics Multi-faceted Approach to the HREE Issue Rare earth recycling Use advanced technology to increase HREE efficiency Increase HREE recovery with Molycorp's advanced process technology Aggressive geological exploration HREE Resources Four high-priority projects One of which is close to Mountain Pass
