Natural Resource Partners L.P.
Increases Distribution
And Issues 2007 Guidance

HOUSTON, January 18, 2007 — Natural Resource Partners L.P. (NYSE:NRP) and (NYSE:NSP) today announced that the Board of Directors of its general partner has declared a fourth quarter 2006 distribution of $0.88 per unit for both NRP and NSP, an increase of $0.03 in its quarterly distribution. This equates to an annualized distribution of $3.52 per unit. The distribution will be paid on February 14, 2007 to unitholders of record on February 1, 2007. This makes the fourteenth consecutive quarter that NRP has increased its distribution and represents a 15% increase over the same period last year.

“We are off to a great start in 2007 by closing two previously announced major acquisitions since the first of the year. Over the last twelve months, NRP has closed eight coal reserve acquisitions, two preparation plant acquisitions and one acquisition of aggregate reserves, allowing us to continue to grow our distributions,” said Corbin J. Robertson, Jr., Chairman and Chief Executive Officer. “Our objective continues to be to grow our distributions by making accretive acquisitions and by actively managing our assets. With the addition of the coal processing and transportation and the aggregates platforms this past year, we now have three platforms for growth and continue to see an active pipeline of opportunities.”

For 2007, NRP expects to generate between $160 million and $180 million in distributable cash flow, up over 40% from NRP’s current 2006 guidance. As in the past, distributable cash flow is shown net of the $9.4 million principal payment due in June on NRP’s senior notes.

Total revenues, which now include coal processing and transportation fees as well as fees associated with NRP’s aggregate reserves, are anticipated to be in a range between $222 million and $238 million. A significant portion of the total revenues will still be generated from coal royalty revenues, which are forecasted to be in a range from $175 million to $185 million based on coal royalty revenue per ton between $2.85 and $2.95. Production volumes are expected to range between 60 million tons and 65 million tons and are more heavily weighted towards the second half of the year, as Williamson and Gatling ramp up production. Override royalties will be up significantly in 2007 as NRP will be receiving royalties from production on adjacent property as NRP lessees mine

those reserves. NRP expects approximately 22% of its production and approximately 27% of its coal royalty revenues to be derived from metallurgical coal.

(1)	Other revenues consist of minimums recognized as revenue, oil and gas revenues, property taxes, override royalties, wheelage, rentals and timber.
(2)	Other expenses include property, franchise and other taxes as well as coal royalty and override payments.
(3)	Distributable cash flow represents net income plus depletion and amortization minus scheduled principal payments on NRP senior notes. Distributable cash flow is a “non-GAAP financial measure” that is presented because management believes it is a useful adjunct to net cash provided by operating activities under GAAP. Distributable cash flow is a significant liquidity metric that is an indicator of NRP’s ability to generate cash flows at a level that can sustain or support an increase in quarterly cash distributions paid to its partners. Distributable cash flow is also the quantitative standard used throughout the investment community with respect to publicly-traded partnerships. Distributable cash flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing or financing activities. We believe that “net cash provided by operating activities” would be the most comparable financial measure to distributable cash. However, due to the substantial uncertainties associated with forecasting future changes to operating assets and liabilities, we cannot provide guidance on forward-looking net cash provided by operating activities or provide reconciliations of distributable cash flow to that measure.
