International Coal Group, Inc. and the Guarantors (as defined below)

Ladies and Gentlemen:

We have acted as counsel for International Coal Group, Inc, a Delaware corporation (the “Company”), in connection with the authorization of the possible issuance and sale from time to time, on a delayed basis, by the Company of $600,000,000 of: (i) shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”); (ii) debt securities of the Company (the “Debt Securities”), in one or more series, certain of which may be (A) guaranteed by the Company’s subsidiaries listed on Annex A hereto (the “Delaware Guarantors”) and Annex B hereto (the “Other Guarantors” and, together with the Delaware Guarantors, the “Guarantors”)) by the issuance from time to time, on a delayed basis, of guarantees of the Debt Securities (the “Guarantees”), and/or (B) convertible into or exchangeable for Common Stock, in each case, as contemplated by the Registration Statement on Form S-3 to which this opinion has been filed as an exhibit (as the same may be amended from time to time, the “Registration Statement”). The Debt Securities, the Common Stock and the Guarantees are collectively referred to herein as the “Securities.” The Securities may be offered and sold from time to time pursuant to Rule 415 under the Securities Act of 1933 (the “Securities Act”).

In connection with the opinions expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of this opinion. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, we are of the opinion that:

1. The shares of Common Stock, upon receipt by the Company of such lawful consideration therefor having a value not less than the par value thereof as the Company’s Board of Directors (or an authorized committee thereof) may determine, will be validly issued, fully paid and nonassessable.

2. The Debt Securities, upon receipt by the Company of such lawful consideration therefor as the Company’s Board of Directors (or an authorized committee thereof) may determine, will constitute valid and binding obligations of the Company.

3. The Guarantees (a) when duly executed by the Guarantors and (b) delivered to the purchaser or purchasers of the related Debt Securities, upon receipt by the Company of such lawful consideration for the related Debt Securities as the Company’s Board of Directors (or a duly authorized committee thereof) may determine, will constitute valid and binding obligations of the Guarantors.
