Acquires Coal Reserves in Illinois Basin

• Definitive agreement to acquire over 200 million tons of Illinois Basin coal reserves in a series of transactions through 2012

• Total purchase price of $255 million

HOUSTON, September 10, 2009 – Natural Resource Partners L.P. (NYSE:NRP) announced today that it has signed a definitive agreement to acquire approximately 200 million tons of coal reserves related to the Deer Run mine in Illinois from Colt LLC, an affiliate of the Cline Group, through eight separate transactions for a total purchase price of $255 million. Upon closing of the first transaction, NRP paid $10.0 million, funded through its credit facility, and acquired approximately 3.3 million tons of reserves associated with the initial production from the mine. Future closings anticipated in 2010, 2011 and 2012 will be associated with the completion of certain milestones relating to the new mine’s construction.

Acquisition Details

The Deer Run mine is located near Hillsboro in Montgomery and Bond Counties, Illinois and the coal reserves are leased to the mining company Hillsboro Energy, an affiliate of the Cline Group. Construction of the new longwall mine has already commenced. Initial production is expected in 2010, and longwall production is expected to commence in 2011.

The acquisition will begin generating revenue for NRP in the first quarter of 2010, and royalty income will grow substantially as production at the new mine comes online. NRP expects approximately $12 million in revenues in 2010 from the Deer Run mine. Production from the mine is forecasted to be approximately eight to ten million tons per year, from which NRP ultimately anticipates receiving in excess of $40 million per year of income. Based upon these production levels, the life of the mine will exceed 20 years. NRP expects the acquisition to be accretive to cash flow in 2010.

“We are excited about the opportunity to acquire additional coal reserves in the Illinois Basin as the Cline team develops this new mine,” said Nick Carter, President and COO. “With this

acquisition, NRP continues its diversification in the Illinois Basin. When this mine is completed and in production, our Illinois Basin production is expected to be approximately 20 million tons per year, up from less than 3 million tons in 2006,” said Carter. “This is the third acquisition in the Illinois Basin resulting from our relationship with the Cline Group, announced in late 2006. There are several acquisitions anticipated over the next few years that will continue to build our production base in the Illinois Basin.”

Partial Forgiveness of Distributions by General Partner and Holders of Incentive Distribution Rights

In conjunction with the closing of the first transaction, the holders of the incentive distribution rights (IDRs) have elected to forgo the distribution associated with the highest splits for the next two quarters. This will result in a savings in distributions of approximately $7.35 million each quarter for a total of $14.7 million. “The general partner and the holders of the IDRs are confident in the future success of both Natural Resource Partners and the new Deer Run mine. Therefore, the IDR holders are willing to forgo these distributions to fund some of the near term cash needed to acquire these quality reserves in the Illinois Basin,” said Corbin J. Robertson, Jr., Chairman and Chief Executive Officer. “Due to the waiver of a portion of the distributions by the general partner and the holders of the IDRs, the net cost of the Deer Run acquisition to the partnership will be approximately $240.7 million.”

Current Market

“We are beginning to see some improvements in the metallurgical market for coal that could bode well for NRP,” said Carter. “Some of our lessees’ mines have started producing again and shipments of metallurgical coal are being delivered both domestically and internationally. As approximately 25% of our normal production is from metallurgical coal, this could have a favorable impact on our performance.”

Mr. Robertson said, “Over the years, NRP has built cash to help sustain the current distribution through temporary periods of lower production volumes or price decreases, as has been experienced through this recent recession. In addition to the $81 million in cash at June 30, 2009, following this first closing, NRP also has $278 million available under its credit facility that is not up for renewal until 2012. While distribution policy is set by the board of directors at quarterly meetings of the board, it is management’s view that NRP will not need to lower the current distribution through the remainder of the year.”
