ITEM 7.01 Regulation FD Disclosure.

On October 29, 2012, Oxford Resource Partners, LP (“Oxford”) issued a press release announcing that it declared a reduced cash distribution of $0.20 per common unit for its third quarter ended September 30, 2012. Oxford additionally announced that it determined that no cash distribution will be paid on its subordinated units for its third quarter ended September 30, 2012. In the press release, Oxford also disclosed that it would announce earnings for the third quarter ended September 30, 2012 before the market opens on Tuesday, November 6, 2012, and will hold a conference call at 10:00 a.m. Eastern Time on the same day to review the results. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The common units distribution will be paid on November 14, 2012 to all common unitholders of record as of the close of business on November 8, 2012.

The information set forth in this Item 7.01 and the attached Exhibit 99.1 includes “forward-looking statements” — that is, statements related to future, not past, events. Forward-looking statements are based on current expectations and include any statement that does not directly relate to a current or historical fact. In this context, forward-looking statements often address expected future business and financial performance, and often contain words such as “anticipate,” “believe,” “intend,” “expect,” “plan” or “will” or other similar words. These forward-looking statements involve certain risks and uncertainties and ultimately may not prove to be accurate. Actual results and future events could differ materially from those anticipated in such statements. For further discussion of risks and uncertainties, you should refer to Oxford’s SEC filings. Oxford undertakes no obligation and does not intend to update any forward-looking statements, whether as a result of new information or future events. All forward-looking statements are qualified in their entirety by this cautionary statement.

The information in Item 7.01 of this Current Report on Form 8-K, including the attached Exhibit 99.1, is being “furnished” pursuant to Item 7.01 and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and is not incorporated by reference into any Oxford filing, whether made before or after the date hereof, regardless of any general incorporation language in such filing.
