Forward Looking Statements The statements made by representatives of Natural Resource Partners L.P. (“NRP”) during the course of this presentation that are not historical facts are forward-looking statements. Although NRP believes that the assumptions underlying these statements are reasonable, investors are cautioned that such forward-looking statements are inherently uncertain and necessarily involve risks that may affect NRP’s business prospects and performance, causing actual results to differ from those discussed during the presentation. Such risks and uncertainties include, by way of example and not of limitation: general business and economic conditions; decreases in demand for coal; changes in our lessees’ operating conditions and costs; changes in the level of costs related to environmental protection and operational safety; unanticipated geologic problems; problems related to force majeure; potential labor relations problems; changes in the legislative or regulatory environment; and lessee production cuts. These and other applicable risks and uncertainties have been described more fully in NRP’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q. NRP undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information or future events.

Overview of NRP’s Coal Business • Acts as a proxy for the coal industry • 5th largest owner of coal reserves in the U.S. – 2.3 billion tons • Strategically located in Appalachia, Illinois Basin, Western U.S. • Increased production expected from development of Ill properties • 2011 coal production of 49.2 mmt and coal royalty revenues of $279.2 million

NRP – Significant Metallurgical Exposure • 20-25% of all the metallurgical coal

produced in the U.S. is produced from NRP properties

– In 2006, it was as high as 30%

• Historically metallurgical coal has made up a significant portion of NRP’s coal royalty revenue

– 22% to 37% of production – 29% to 47% of coal royalty revenues – 2Q 2012 YTD - 33% of production and 45%

of coal royalty revenues

• 17 lessees currently produce metallurgical coal from NRP properties

• Increases in metallurgical demand or prices can have a profound impact on NRP

U.S. Coal Production (5-Year Average)

NRP’s % of U.S. Met Production (5-Year Average)

NRP’s Illinois Basin Growth Prospects • 2005 increased exposure to Illinois Basin

• Production increased – 5% to 24% of total today – expected to continue to grow

• Invested ~$586 million

• Projects recent completion – Hillsboro (Deer Run) –should add 7-9 million tons on an annual basis – Sugar Camp infrastructure and ORRI – add ~$8 million in cash flows in 2012

• Agreement with Cline Group - opportunities on up to 3 billion tons of coal reserves or infrastructure

• Illinois Basin coal well situated – Additional scrubbers to handle Ill Basin coal – Transportation and BTU advantage over PRB coals – Thicker coal seams than Appalachia means very low operating costs compared to CAPP – Export capability through the mouth of the Mississippi River

8

Growing Infrastructure Business

9

• Own preparation plants, rail load-outs and beltline structures for both coal and aggregates

• Currently own 11 coal assets and 1 aggregate plant

• Fees received based on • % of the gross selling price or • Fixed fee per ton of throughput

• Recent Ill. Basin acquisition to provide

significant increase for 2012 and beyond

• Working to expand business

Overview of NRP’s Aggregates Business • 380 million tons of aggregates in 8 states • Currently less than 2% of revenues ($6.7 mm in 2011 on 5.9 mm tons production), but growing • Invested ~ $130 million since 2006 to acquire assets

– Additional un-leased mineral interests throughout United States

• Interest types include fee mineral ownership, overriding royalty ownership

– Actively work with operators to provide best scenario for successful development

• Recent acquisitions include 19,200 net acres within the active Mississippian Lime play

• Actively seeking to grow oil and gas portfolio through acquisitions

– Minerals, royalties, ORRI, Net Profits Interest acquisitions

Oil and Gas Revenues from NRP’s Assets

States in which NRP has Oil and Gas Revenue

Growing Oil and Gas Royalties • In 2011 hired oil and gas team to focus on acquisitions of additional royalty properties

and leasing of currently owned mineral acreage for oil and gas development

• Since Dec 2011 acquired 19,200 net mineral acres in the Mississippian Lime oil play in

Oklahoma for ~$64 million – Currently leased to several active operators – Continuing development through horizontal drilling

• Continuing to lease BRP oil and gas acreage

• Actively working on leasing additional NRP properties

• Oil and Gas royalties currently only 4% of revenues, but growing as further development occurs on NRP properties

Platform for Additional Growth -BRP Mineral Venture - ~ 9 mm acres •Formed venture with International Paper June 2010 - BRP •Own and manage ~9.1 million acres of mineral rights previously held by IP •NRP paid $42.5 million and has annual cumulative preferred distribution of $4.25 MM and 51% of any excess income •Royalty based model similar to NRP other assets •NRP has received distributions with regard to:

•2012 (Jan – Apr) - $3.7 million •2011 - $6.9 million •2010 - $2.5 million (7 months)

15

• Current quarterly distribution - $0.55 per unit

• Large cash balance to help protect distribution in weak markets

Unique Tax Attributes for Individuals • Portion of current income deferred due to depletion, depreciation

• Current income predominantly taxed at Section 1231 – capital gains rates

• At sale of units - very little recapture of depreciation and depletion

• If units are held for more than one year, majority of all income generated by the partnership is taxed at capital gains rates

16

Poised for Growth in 2013 and beyond • Potential for Higher 2012 coal production

– NRP’s lessees produced 49.2 million tons in 2011 – NRP forecasts 2012 coal production of 48 million tons to 54 million tons

• Some lessees moving back onto NRP property from other lessees • Increasing ILB tonnage in 2012 and 2013 based on earlier acquisitions

• Growth in infrastructure and transportation – Increasing throughput from rising coal tonnage in ILB – New ILB infrastructure assets – Sugar Camp – New infrastructure assets in aggregates

• Growth in oil and gas due to recent acquisitions

• Increased aggregates platform – Since 2009 acquired 9 properties for ~$102 million – Combination of producing and greenfield projects – Providing growth in 2012 and beyond

• Mineral venture with International Paper (BRP LLC)

Current Coal Markets • Weak domestic thermal market

– Historically high inventories – Low natural gas prices – Unseasonable weather – Regulatory environment

• Weaker but Stable Met market – Domestic steel production increased 2012 – Global met coal quarterly benchmark increased to $225 but expected to drop to ~ $190 as a

bottom

• Exports at new highs – 2011 exports of 107 mm tons – all time high – June YTD exports reported at 66.0 mm tons – 24% above the same period last year – 2012 expected to exceed 2011 – New export capacity proposed – could reach as high as 270 mm tons if all proposed get

built
