Item 8.01. Other Events.

This Current Report on Form 8-K updates the Annual Report on Form 10-K of Molycorp, Inc. (the “Company”) for the year ended December 31, 2010 (the “Form 10-K”) and the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2011 (the “Form 10-Q”), which were filed on March 9, 2011 and May 10, 2011, respectively.

As previously reported on a Current Report on Form 8-K filed by the Company on May 25, 2011, the Company determined in May 2011 that its work in process inventory of ceric hydrate was overstated by approximately $1.7 million as of December 31, 2010 and by approximately $3.0 million as of March 31, 2011, $1.3 million of which related to the three months ended March 31, 2011 and $1.7 million related to the fourth quarter of 2010, which was also revised.

The Company has adjusted its consolidated financial statements for the year ended December 31, 2010 and for the three months ended March 31, 2011 to eliminate the overstatement of its work in process inventory of ceric hydrate. Such revised consolidated financial statements were previously included in the Company’s Registration Statement on Form S-1 (Registration No. 333-174458) filed on May 24, 2011. The revised financial statements included in Exhibit 99.1 to this Current Report on Form 8-K update and supersede the Company’s financial statements included as Item 8 on the Form 10-K and included as Item 1 on the Form 10-Q. Additionally, Exhibit 99.1 to this Current Report on Form 8-K updates the Selected Financial Data included as Item 6 and Management’s Discussion and Analysis of Financial Condition and Results of Operations included as Item 7 on the Form 10-K and as Item 2 on the Form 10-Q.

Further, the Company has assessed the materiality of this misstatement in accordance with the SEC’s Staff Accounting Bulletin No. 99 and concluded that this error is not material to the Company’s previously issued consolidated financial statements.

All other items of the Form 10-K and the Form 10-Q remain unchanged, and no attempt has been made to update matters in the Form 10-K or the Form 10-Q, except to the extent expressly provided above.
