We also have examined the originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and have made such other investigations as we have deemed relevant and necessary in connection with the opinions hereinafter set forth. As to questions of fact material to this opinion, we have relied upon certificates or comparable documents of public officials and of officers and representatives of the Company and the Guarantors.

We also have assumed that each of the 2020 Notes Indenture and the 2021 Notes Indenture is the valid and legally binding obligation of the Trustee.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that:

1. When (a) the 2020 Exchange Securities have been duly executed, authenticated, issued and delivered in accordance with the provisions of the 2020 Notes Indenture upon the exchange and (b) the 2020 Exchange Securities Guarantee of Walter Energy Holdings, LLC has been duly issued, the 2020 Exchange Securities Guarantee of Walter Energy Holdings, LLC will constitute the valid and legally binding obligation of Walter Energy Holdings, LLC, enforceable against Walter Energy Holdings, LLC in accordance with its terms.

Our opinions set forth above are subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) an implied covenant of good faith and fair dealing.

We do not express any opinion herein concerning any law other than the law of the State of New York and the Delaware Limited Liability Company Act.

We hereby consent to the filing of this opinion letter as Exhibit 5.4 to the Registration Statement and to the use of our name under the caption “Legal Matters” in the Prospectus included in the Registration Statement.
