Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains certain “forward-looking statements.” Statements included in this report that are not historical facts, that address activities, events or developments that we expect or anticipate will or may occur in the future, including things such as plans for growth of the business, future capital expenditures, competitive strengths, goals, references to future goals or intentions or other such references are forward-looking statements. These statements can be identified by the use of forward-looking terminology, including “may,” “believe,” “expect,” “anticipate,” “estimate,” “continue,” or similar words. These statements are made by us based on our past experience and our perception of historical trends, current conditions and expected future developments as well as other considerations we believe are reasonable as and when made. Whether actual results and developments in the future will conform to our expectations is subject to numerous risks and uncertainties, many of which are beyond our control. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in these statements.

Any differences could be caused by a number of factors, including, but not limited to: changes in governmental regulation of the mining industry or the electric utility industry; adverse weather conditions and natural disasters; weakness in global economic conditions; decreases in demand for electricity and changes in demand for coal; poor mining conditions resulting from geological conditions or the effects of prior mining; equipment problems at mining locations; the availability of transportation for coal shipments; the availability and costs of key supplies and commodities such as steel, diesel fuel and explosives; the availability and prices of competing electricity generation fuels; our ability to secure or acquire high-quality coal reserves; and our ability to find buyers for coal under favorable supply contracts. Other factors that could cause our actual results to differ from our projected results are described in (1) Part II, “Item 1A. Risk Factors” and elsewhere in this Form 10-Q, (2) our Annual Report on Form 10-K for the year ended December 31, 2011, (3) our reports and registration statements filed from time to time with the Securities and Exchange Commission and (4) other announcements we make from time to time. In addition, we may be subject to unforeseen risks that may have a materially adverse effect on us.  Accordingly no assurances can be given that the actual events and results will not be materially different than the anticipated results described in the forward-looking statements.

The forward-looking statements speak only as of the date made, and, other than as required by law, and we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

RHINO RESOURCE PARTNERS LP

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

AS OF MARCH 31, 2012 AND DECEMBER 31, 2011 AND FOR THE THREE MONTHS ENDED MARCH 31, 2012 AND 2011

1. BASIS OF PRESENTATION AND ORGANIZATION

Basis of Presentation and Principles of Consolidation— The accompanying unaudited interim financial statements include the accounts of Rhino Resource Partners LP (the “Partnership”) and its subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.

Unaudited Interim Financial Information—The accompanying unaudited interim financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. The condensed consolidated statement of financial position as of March 31, 2012, condensed consolidated statements of operations for the three month periods ended March 31, 2012 and 2011 and the condensed consolidated statements of cash flows for the three months ended March 31, 2012 and 2011 include all adjustments (consisting of normal recurring adjustments) which the Partnership considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The condensed consolidated statement of financial position as of December 31, 2011 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S.”). The Partnership filed its Annual Report on Form 10-K for the year ended December 31, 2011 with the Securities and Exchange Commission (“SEC”), which included all information and notes necessary for such presentation. The results of operations for the interim period are not necessarily indicative of the results to be expected for the year or any future period. These unaudited interim financial statements should be read in conjunction with the audited financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2011 filed with the SEC.

Organization—The Partnership is a Delaware limited partnership formed on April 19, 2010 to acquire Rhino Energy LLC (the “Predecessor” or the “Operating Company”), an entity engaged primarily in the mining and sale of coal. The Partnership had no operations during the period from April 19, 2010 (date of inception) to October 5, 2010 (the consummation of the IPO of the Partnership). The Operating Company and its wholly owned subsidiaries produce and market coal from surface and underground mines in Kentucky, Ohio, West Virginia, and Utah and also have one underground mine located in Colorado that remained temporarily idled at March 31, 2012. The majority of the Operating Company’s sales are made to domestic utilities and other coal-related organizations in the United States. In addition to operating coal properties, the Operating Company manages and leases coal properties and collects royalties from such management and leasing activities. The Operating Company was formed in April 2003 and has been built via acquisitions.

In addition to the Operating Company’s coal operations, the Partnership has invested in oil and gas mineral rights that began to generate royalty revenues in the three months ended March 31, 2012.

Follow-on Offering

On July 18, 2011, the Partnership completed a public offering of 2,875,000 common units, representing limited partner interests in the Partnership, at a price of $24.50 per common unit. Of the common units issued, 375,000 units were issued in connection with the exercise of the underwriters’ option to purchase additional units. Net proceeds from the offering were approximately $66.4 million, after deducting underwriting discounts and offering expenses of approximately $4.1 million. The Partnership used the net proceeds from this offering, and a related capital contribution by the Partnership’s general partner (the “General Partner”) of approximately $1.4 million, to repay approximately $67.8 million of outstanding indebtedness under the Partnership’s credit facility.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND GENERAL

Investment in Joint Venture.  Investments in other entities are accounted for using the consolidation, equity method or cost basis depending upon the level of ownership, the Partnership’s ability to exercise significant influence over the operating and financial policies of the investee and whether the Partnership is determined to be the primary beneficiary of a variable interest entity. Equity investments are recorded at original cost and adjusted periodically to recognize the Partnership’s proportionate share of the investees’ net income or losses after the date of investment. Any losses from the Partnership’s equity method investment are absorbed by the Partnership based upon its proportionate ownership percentage. If losses are incurred that exceed the Partnership’s investment in the equity method entity, then the Partnership must continue to record its proportionate share of losses in excess of its investment. Investments are written down only when there is clear evidence that a decline in value that is other than temporary has occurred.

In May 2008, the Operating Company entered into a joint venture, Rhino Eastern LLC (“Rhino Eastern”), with an affiliate of Patriot Coal Corporation (“Patriot”) to acquire the Eagle mining complex. To initially capitalize the joint venture, the Operating Company contributed approximately $16.1 million for a 51% ownership interest in the joint venture and accounts for the investment in the joint venture and its results of operations under the equity method. The Partnership considers the operations of this entity to comprise a reporting segment (“Eastern Met”) and has provided additional detail related to this operation in Note 18, “Segment Information.” As of March 31, 2012 and 2011, the Partnership has recorded its Rhino Eastern equity method investment of $20.8 million and $18.7 million, respectively, as a long-term asset. During the first quarter of 2012, the Partnership provided loans based upon its ownership share to the Rhino Eastern joint venture in the amount of $4.6 million and $2.8 million was still outstanding as of March 31, 2012, which is recorded in Prepaid expenses and other on the Partnership’s unaudited condensed consolidated statements of financial position.

In March 2012, the Partnership made an initial investment of approximately $0.1 million in a new joint venture, Timber Wolf, with affiliates of Wexford Capital LP (“Wexford Capital”).  Timber Wolf was formed to construct and operate a condensate river terminal that will provide barge trans-loading services for parties conducting activities in the Utica Shale region of eastern Ohio.  The initial investment was the Partnership’s proportionate minority ownership share to purchase land for the construction site of the condensate river terminal. Timber Wolf had no

6

operating activities during the first quarter of 2012 and the Partnership will initially include any operating activities of Timber Wolf in its Other category.

Recently Issued Accounting Standards. In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”. This ASU changes certain fair value measurement principles and clarifies the application of existing fair value measurement guidance. Amendments included in this ASU clarify the intent about the application of existing fair value measurement including the application of the highest and best use and valuation premise concepts. The amendments in this ASU specify that the concepts of highest and best use and valuation premise in a fair value measurement are relevant only when measuring the fair value of nonfinancial assets and are not relevant when measuring the fair value of financial assets or of liabilities. This ASU also requires additional fair value disclosures including a qualitative discussion about the sensitivity of recurring Level 3 fair value measurements and the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial position, but for which the fair value is required to be disclosed. The ASU is effective for interim and annual periods beginning after December 15, 2011 and are to be applied prospectively. While this ASU does not have an impact on the Partnership’s financial results, additional disclosures are required in the notes to the Partnership’s financial statements.

In September 2011, the FASB published ASU No. 2011-08, “Intangibles—Goodwill and Other (Topic 350) Testing Goodwill for Impairment”. Under the amendments in this ASU, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step goodwill impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if any. Under the amendments in this ASU, an entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 and early adoption is permitted. The Partnership does not believe this new accounting guidance will have a material effect on its financial results.

In June 2011, the FASB published ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”. Under the amendments in this ASU, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity

7

is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. In a single continuous statement, the entity is required to present the components of net income and total net income, the components of other comprehensive income and a total for other comprehensive income, along with the total of comprehensive income in that statement. In the two-statement approach, an entity is required to present components of net income and total net income in the statement of net income. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive income. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The amendments in this ASU do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The amendments do not change the option for an entity to present components of other comprehensive income either net of related tax effects or before related tax effects, with one amount shown for the aggregate income tax expense or benefit related to the total of other comprehensive income items. In both cases, the tax effect for each component must be disclosed in the notes to the financial statements or presented in the statement in which other comprehensive income is presented. The amendments do not affect how earnings per share is calculated or presented. For public entities, the amendments of this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011.

Subsequently, in December 2011, the FASB issued ASU No. 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”. In order to defer only those changes in Update 2011-05 that relate to the presentation of reclassification adjustments, the paragraphs in this ASU supersede certain pending paragraphs in ASU 2011-05. The amendments are being made to allow the FASB time to re-deliberate whether to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. While the FASB is considering the operational concerns about the presentation requirements for reclassification adjustments and the needs of financial statement users for additional information about reclassification adjustments, entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect before ASU 2011-05. All other requirements in ASU 2011-05 are not affected by this ASU 2011-12, including the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements. Public entities should apply these requirements for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Partnership has consistently presented comprehensive income in a single continuous statement with net income, so the provisions of ASU 2011-05 and the related deferral included in ASU 2011-12 did not have a material effect on the Partnership.

3. BUSINESS COMBINATIONS AND OTHER ACQUISITIONS

Acquisition of The Elk Horn Coal Company, LLC

In June 2011, the Partnership completed the acquisition of 100% of the ownership interests in The Elk Horn Coal Company, LLC (“Elk Horn”) for approximately $119.7 million in cash consideration, or approximately $119.6 million net of cash acquired (referred to as the “Elk Horn Acquisition”). Elk Horn is primarily a coal leasing company that owns or controls coal reserves and non-reserve coal deposits and surface acreage in eastern Kentucky. The Elk Horn acquisition was initially funded with borrowings under the Partnership’s credit facility. The Partnership completed a public offering of the Partnership’s common units in July 2011 that provided proceeds the Partnership used to repay existing indebtedness on its credit facility that was incurred from the Elk Horn acquisition. The following table summarizes the assets acquired and liabilities assumed as of the acquisition date:

	(in thousands)
Cash	$	58
Accounts receivable	2,619
Prepaid expenses and other	94
Property, plant and equipment	7,056
Mine development costs	3,000
Coal properties	112,057
Intangible assets	654
Other non-current assets	1,112
Accounts payable	(79		)
Deferred revenues	(2,499		)
Accrued expenses and other	(1,691		)
Asset retirement obligations	(2,707		)
Net assets acquired	119,674
Total consideration	$	119,674

Although the responsibility of valuation remains with the Partnership’s management, the determination of the fair values of the various assets and liabilities acquired were based in part upon studies conducted by third party professionals with experience in the appropriate subject matter. The studies related to the value of the property, plant and equipment, coal properties, intangible assets acquired and asset retirement obligations. The table above reflects the allocation of the purchase price to the fair value of the assets acquired and liabilities assumed in the Elk Horn acquisition, which resulted in no recognition of goodwill or gain on the acquisition. The Partnership’s unaudited condensed consolidated statements of operations and comprehensive income do not include revenue, costs or net income from Elk Horn prior to June 10, 2011, the effective date of the acquisition.

The following table presents selected unaudited pro forma financial information for the three months ended March 31, 2011, as if the acquisition had occurred on January 1, 2010. The pro forma information was prepared using Elk Horn’s historical financial data and also reflects adjustments based upon assumptions by the Partnership’s management to give effect for certain

9

pro forma items that are directly attributable to the acquisition. These pro forma adjustment items include increased depletion expense related to the step-up in basis for the mineral assets acquired and increased interest expense from borrowings incurred to fund the acquisition. The pro forma adjustments for interest expense and earnings per unit reflect the net amount of the additional borrowings incurred by the Partnership in June 2011 to initially fund the acquisition that were partially offset by proceeds from common units issued in a public offering completed in July 2011. Supplemental pro forma revenue, net earnings and earnings per unit disclosures are as follows.

Acquisition of Oil and Gas Mineral Rights

During the year ended December 31, 2011, the Partnership completed the acquisition of certain oil and gas mineral rights in the Cana Woodford region of western Oklahoma for a total purchase price of approximately $8.1 million. The Partnership began to receive royalty revenues from these mineral rights in the three months ended March 31, 2012.

The Partnership and an affiliate of Wexford Capital have participated with Gulfport Energy, a publicly traded company, to acquire interests in a portfolio of oil and gas leases in the Utica Shale. An affiliate of Wexford Capital owns approximately 13.3% of the common stock of Gulfport Energy as of February 20, 2012. During the year ended December 31, 2011, the Partnership completed the acquisitions of interests in a portfolio of leases in the Utica Shale region of eastern Ohio for a total purchase price of approximately $19.9 million. The Partnership is evaluating future alternatives for its Utica Shale investment.

On March 6, 2012, the Partnership completed a lease agreement with a third party for an estimated 1,500 acres the Partnership previously owned in the Utica Shale region in Harrison County Ohio. The lease agreement is for an initial five year term with an optional three year renewal period and conveys rights to the third party to perform drilling and operating activities for producing oil, natural gas or other hydrocarbons. As part of the lease agreement, the third party agreed to pay the Partnership the sum of $6,000 per acre as a lease bonus, of which $0.5

10

million was paid at the signing of the lease agreement. The remainder of the lease bonus payment shall be paid by the third party to the Partnership within 90 days from the date the lease agreement was signed. In addition, the lease agreement stipulates that the third party shall pay the Partnership a 20% royalty based upon the gross proceeds received from the sale of oil and/or natural gas recovered from the leased property. For the three months ended March 31, 2012, the Partnership recorded the $0.5 million related to the initial lease bonus payment within Other revenues and has not recorded any additional amounts related to the remaining lease bonus payment due to pending legal verification of marketable title of the related acreage.

Acquisition of Coal Property

In August 2011, the Partnership purchased non-reserve coal deposits at its Sands Hill operation for approximately $2.5 million, which is estimated to include approximately 2.5 million tons of non-reserve coal deposits.

In June 2011, the Partnership acquired approximately 32,600 acres and associated surface rights in Randolph and Upshur Counties, West Virginia for approximately $7.5 million. These development stage properties are unpermitted and contain no infrastructure. The Partnership plans to fully explore these properties and intends to confirm additional mineable underground metallurgical coal reserves and eventually commence production.

Senior Secured Credit Facility with PNC Bank, N.A.—The original maximum availability under the credit facility by and among the Operating Company, the guarantors (including the Partnership) and lenders which are parties thereto, and PNC Bank, N.A. as administrative agent was $200.0 million. On June 8, 2011, with the consent of the lenders, the Operating Company exercised the option to increase the amount available to borrow under the credit agreement by $50.0 million to $250.0 million as part of the Elk Horn acquisition. As part of exercising this option to increase the available amount under the credit agreement, the

15

Operating Company paid a fee of $1.0 million to the lenders, which was recorded in Debt issuance costs in Other non-current assets on the Partnership’s unaudited condensed consolidated statements of financial position.

On July 29, 2011, the Operating Company and the Partnership, as a guarantor, executed an amended and restated senior secured credit facility with PNC Bank, N.A., as administrative agent, and a group of lenders, which are parties thereto. The maximum availability under the amended and restated credit facility is $300.0 million, with a one-time option to increase the availability by an amount not to exceed $50.0 million. Of the $300.0 million, $75.0 million is available for letters of credit. Borrowings under the facility bear interest, which varies depending upon the levels of certain financial ratios. As part of the agreement, the Operating Company is required to pay a commitment fee on the unused portion of the borrowing availability that also varies depending upon the levels of certain financial ratios. Borrowings on the amended and restated senior secured credit facility are collateralized by all of the unsecured assets of the Partnership. The amended and restated senior secured credit facility requires the Partnership to maintain certain minimum financial ratios and contains certain restrictive provisions, including among others, restrictions on making loans, investments and advances, incurring additional indebtedness, guaranteeing indebtedness, creating liens, and selling or assigning stock. The Partnership was in compliance with all covenants contained in the amended and restated senior secured credit facility as of and for the period ended March 31, 2012. The amended and restated senior secured credit facility expires in July 2016.

As part of executing the amended and restated senior secured credit facility, the Operating Company paid a fee of approximately $2.8 million to the lenders, which was recorded in Debt issuance costs in Other non-current assets on the Partnership’s unaudited condensed consolidated statements of financial position.

At March 31, 2012, the Operating Company had borrowed $155.0 million at a variable interest rate of LIBOR plus 2.75% (3.00% at March 31, 2012) and an additional $6.6 million at a variable interest rate of PRIME plus 2.00% (5.00% at March 31, 2012). In addition, the Operating Company had outstanding letters of credit of approximately $26.8 million at a fixed interest rate of 2.75% at March 31, 2012. The Operating Company had not used $111.7 million of the borrowing availability at March 31, 2012.

Note payable to H&L Construction Co., Inc.— The note payable to H&L Construction Co., Inc. was originally a non-interest bearing note and the Partnership has recorded a discount for imputed interest at a rate of 5.0% on this note that is being amortized over the life of the note using the effective interest method. The note payable matures in January 2015. The note is secured by mineral rights purchased by the Partnership from H&L Construction Co., Inc. with a carrying amount of approximately $11.5 million and approximately $11.6 million at March 31, 2012 and December 31, 2011, respectively.

12. EQUITY-BASED COMPENSATION

In October 2010, the General Partner established the Rhino Long-Term Incentive Plan (the “Plan” or “LTIP”). The Plan is intended to promote the interests of the Partnership by providing to employees, consultants and directors of the General Partner, the Partnership or affiliates of either incentive compensation awards to encourage superior performance. The LTIP provides for grants of restricted units, unit options, unit appreciation rights, phantom units, unit awards, and other unit-based awards.

As of March 31, 2012, the General Partner granted phantom units to certain employees and restricted units and unit awards to its directors. A portion of these grants were made in connection with the IPO completed during October 2010, as well as annual restricted unit awards to directors and phantom unit awards granted in the first quarter of 2012 to certain employees in connection with fiscal year 2011 performance. A total of 20,664 phantom units were granted in the first quarter of 2012 and these awards vest in equal annual installments over a three year period from the date of grant. The remaining terms and conditions of these phantom unit awards are similar to the phantom units awarded in connection with the Partnership’s IPO. The total fair value of the awards granted in the first quarter of 2012 was approximately $0.4 million at the grant date and the fair value of these awards remained approximately $0.4 million as of March 31, 2012. The expense related to these awards will be recognized ratably over the three year vesting period, plus any mark-to-market expense, and the amount of expense recognized in the three months ended March 31, 2012 related to these awards was immaterial.

With the vesting of the first portion of the employees’ awards in early April 2011, the Compensation Committee of the board of directors of the General Partner elected to pay some of the awards in cash or a combination of cash and common units. This election was a change in policy since management had previously planned to settle all employee awards with units upon vesting as per the grant agreements. This policy change resulted in a modification of all employee awards from equity to liability classification as of March 31, 2011. The Partnership recorded approximately $0.1 million in incremental compensation expense for the three months ended March 31, 2011 due to the modification of these awards. For the three months ended March 31, 2012, the Partnership did not record any incremental compensation expense due to the modification of these awards since the market price of the Partnership’s common units was below the IPO grant price.

13. COMMITMENTS AND CONTINGENCIES

Coal Sales Contracts and Contingencies—As of March 31, 2012, the Partnership had commitments under sales contracts to deliver annually scheduled base quantities of approximately 3.9 million, 3.5 million, 2.0 million and 0.3 million tons of coal to 16 customers in 2012, 7 customers in 2013, 4 customer in 2014 and 1 customer in 2015, respectively. Some of the contracts have sales price adjustment provisions, subject to certain limitations and adjustments, based on a variety of factors and indices.

The Partnership received a notice from one of its major customers in early April 2012 announcing it would be delaying some of its contracted steam coal shipments from the Partnership’s Central Appalachia and Northern Appalachia operations for an undefined period of time due to an over-supply of coal at its locations. While this customer has acknowledged its contractual obligation, the Partnership is working with this customer to schedule its contracted steam coal purchases and this customer has recently taken limited shipments from the Partnership’s operations. Substantial uncertainty remains as to the impact on the Partnership and its results of operations of future decisions by this major customer regarding its delayed shipments.

Purchase Commitments—As of March 31, 2012, the Partnership had approximately 3.0 million gallons remaining on a commitment to purchase diesel fuel at fixed prices through December 2012 for approximately $10.5 million.

Purchased Coal Expenses—The Partnership incurs purchased coal expense from time to time related to coal purchase contracts. In addition, the Partnership incurs expense from time to time related to coal purchased on the over-the-counter market (“OTC”). Purchased coal expense from coal purchase contracts and expense from OTC purchases for the three months ended March 31, 2012 and 2011 were as follows:

	Three months ended March 31,

19

Leases—The Partnership leases various mining, transportation and other equipment under operating leases. The Partnership also leases coal reserves under agreements that call for royalties to be paid as the coal is mined. Lease and royalty expense for the three months ended March 31, 2012 and 2011 was as follows:

	Three months ended March 31,
	2012		2011
	(in thousands)

Royalty expense	$	4,286	$	3,836

Joint Ventures—Pursuant to the Rhino Eastern joint venture agreement with Patriot, the Partnership is required to contribute additional capital to assist in funding the development and operations of the Rhino Eastern joint venture. During the three months ended March 31, 2012 and 2011, the Partnership did not make any capital contributions to the Rhino Eastern joint venture. The Partnership may be required to contribute additional capital to the Rhino Eastern joint venture in subsequent periods.

The Partnership may contribute additional capital to the Timber Wolf joint venture that was formed in the first quarter of 2012.  The Partnership made an initial capital contribution of approximately $0.1 million during the three months ended March 31, 2012 based upon its proportionate ownership interest.

18. SEGMENT INFORMATION

The Partnership produces and markets coal from surface and underground mines in Kentucky, West Virginia, Ohio and Utah and also has one underground mine located in Colorado that was temporarily idled. The Partnership sells primarily to electric utilities in the United States. In addition, with the acquisition of Elk Horn, the Partnership also leases coal reserves to third parties in exchange for royalty revenues. For the three months ended March 31, 2012, the Partnership had four reportable segments: Central Appalachia (comprised of both surface and underground mines located in Eastern Kentucky and Southern West Virginia, along with the Elk Horn operations), Northern Appalachia (comprised of both surface and underground mines located in Ohio), Rhino Western (comprised of underground mines in Colorado and Utah) and Eastern Met (comprised solely of the joint venture with Patriot). Additionally, the Partnership has an Other category that is comprised of the Partnership’s ancillary businesses. The Partnership has not provided disclosure of total expenditures by segment for long-lived assets, as the Partnership does not maintain discrete financial information concerning segment expenditures for long lived assets, and accordingly such information is not provided to the Partnership’s chief operating decision maker.

The Partnership accounts for the Rhino Eastern joint venture under the equity method. Under the equity method of accounting, the Partnership has only presented limited information (net income). The Partnership considers this operation to comprise a separate operating segment and has presented additional operating detail, with corresponding eliminations and adjustments to reflect its percentage of ownership.

Reportable segment results of operations for the three months ended March 31, 2012 are as follows (Note: “DD&A” refers to depreciation, depletion and amortization):

19.  SUBSEQUENT EVENTS

On April 20, 2012, the Partnership announced a cash distribution of $0.48 per common unit and subordinated unit, or $1.92 per unit on an annualized basis. This distribution will be paid on May 15, 2012 to all unit holders of record as of the close of business on May 1, 2012.

In May 2012, the Partnership completed the purchase of certain rights to coal leases and surface property located in Daviess and McLean counties in western Kentucky for approximately $1.5 million. In addition, the Partnership could potentially pay an additional $3 million related to this acquisition if certain conditions are met. The coal leases and property are estimated to contain approximately 30 million tons of non-reserve coal deposits that are contiguous to the Green River. The property is undeveloped, but fully permitted, and provides the Partnership with access to Illinois Basin coal that is adjacent to a navigable waterway, which could be exported to non-U.S. customers. The Partnership has not completed its accounting analysis for this acquisition.

Overview

We are a growth oriented Delaware limited partnership formed to control and operate coal properties and invest in other natural resource assets. We produce, process and sell high quality coal of various steam and metallurgical grades. We market our steam coal primarily to electric utility companies as fuel for their steam powered generators. Customers for our metallurgical coal are primarily steel and coke producers who use our coal to produce coke, which is used as a raw material in the steel manufacturing process. In addition to operating coal properties, we manage and lease coal properties and collect royalties from those management and leasing activities. In addition to our coal operations, we have invested in oil and gas mineral rights that began to generate royalty revenues in the first quarter of 2012.

We have a geographically diverse asset base with coal reserves located in Central Appalachia, Northern Appalachia, the Illinois Basin and the Western Bituminous region. As of December 31, 2011, we controlled an estimated 437.0 million tons of proven and probable coal reserves, consisting of an estimated 415.6 million tons of steam coal and an estimated 21.4 million tons of metallurgical coal. In addition, as of December 31, 2011, we controlled an estimated 417.1 million tons of non-reserve coal deposits. As of December 31, 2011, Rhino Eastern LLC, a joint venture in which we have a 51% membership interest and for which we serve as manager, controlled an estimated 43.4 million tons of proven and probable coal reserves at the Rhino Eastern mining complex located in Central Appalachia, consisting entirely of premium mid-vol and low-vol metallurgical coal, and an estimated 17.9 million tons of non-reserve coal deposits. As of March 31, 2012, we operated nine mines, including five underground and four surface mines, located in Kentucky, Ohio, West Virginia and Utah. In addition, our joint venture operates two underground mines in West Virginia. In addition, we

24

have one underground mine in Colorado that has been temporarily idled. The number of mines that we operate may vary from time to time depending on a number of factors, including the demand for and price of coal, depletion of economically recoverable reserves and availability of experienced labor.

Our principal business strategy is to safely, efficiently and profitably produce, sell and lease both steam and metallurgical coal from our diverse asset base in order to maintain and, over time, increase our quarterly cash distributions. In addition, we intend to expand our operations through strategic acquisitions, including the acquisition of stable, cash generating natural resource assets. We believe that such assets would allow us to grow our cash available for distribution and enhance stability of our cash flow.

For the three months ended March 31, 2012, we generated revenues of approximately $81.9 million and net income of approximately $9.0 million. Excluding results from the joint venture, for the three months ended March 31, 2012, we produced approximately 1.3 million tons of coal and sold approximately 1.1 million tons of coal, approximately 86% of which were pursuant to supply contracts. Additionally, the joint venture produced and sold approximately 0.1 million tons of premium mid-vol metallurgical coal for the three months ended March 31, 2012.

Recent Developments

Joint Venture Investment

In March of 2012, we made an initial investment of approximately $0.1 million in a new joint venture, Timber Wolf, with affiliates of Wexford Capital.  Timber Wolf was formed to construct and operate a condensate river terminal that will provide barge trans-loading services for parties conducting activities in the Utica Shale region of eastern Ohio.  The initial investment was our proportionate minority ownership share to purchase land for the construction site of the condensate river terminal. Timber Wolf had no operating activities during the first quarter of 2012.

In addition, we are participating in the formation of a services company to provide drill pad construction services in the Utica Shale for drilling operators. This services company has not been formalized and had no operating activities during the first quarter of 2012.

Coal Acquisitions

Acquisition of Coal Property

In May 2012, we completed the purchase of certain rights to coal leases and surface property located in Daviess and McLean counties in western Kentucky for approximately $1.5 million. In addition, the Partnership could potentially pay an additional $3 million related to this acquisition if certain conditions are met. The coal leases and property are estimated to contain approximately 30 million tons of non-reserve coal deposits that are contiguous to the Green River. The property is undeveloped, but fully permitted, and provides us with access to Illinois Basin coal that is adjacent to a navigable waterway, which could be exported to non-U.S. customers.

25

In August 2011, we purchased non-reserve coal deposits at our Sands Hill operation for approximately $2.5 million, which is estimated to include approximately 2.5 million tons.

In June 2011, we acquired approximately 32,600 acres and associated surface rights in Randolph and Upshur Counties, West Virginia for approximately $7.5 million. These development stage properties are not permitted and contain no infrastructure. We plan to fully explore these properties and intend to prove up additional mineable underground metallurgical coal reserves for future mining.

Acquisition of The Elk Horn Coal Company, LLC

In June 2011, we completed the acquisition of 100% of the ownership interests in Elk Horn for approximately $119.7 million in cash consideration. Elk Horn is primarily a coal leasing company located in eastern Kentucky that is expected to provide us with royalty revenues in future periods. The Elk Horn acquisition was funded with borrowings available under our credit facility, which were subsequently repaid with proceeds from an offering of our common units.

Oil and Gas Investments

During the year ended 2011, we completed the acquisition of certain oil and gas mineral rights in the Cana Woodford region of western Oklahoma for a total purchase price of approximately $8.1 million. We began to receive royalty revenues from these mineral rights in the first quarter of 2012.

We and an affiliate of Wexford Capital have participated with Gulfport Energy, a publicly traded company, to acquire interests in a portfolio of oil and gas leases in the Utica Shale. As of February 20, 2012, an affiliate of Wexford Capital owned approximately 13.3% of the common stock of Gulfport Energy. During the year ended December 31, 2011, we completed the acquisitions of interests in a portfolio of leases in the Utica Shale region of eastern Ohio for a total purchase price of approximately $19.9 million.

In March 2012, we completed an out-lease agreement with a third party for an estimated 1,500 acres we own in the Utica Shale region of Harrison County Ohio. The lease agreement is for an initial five year term with an optional three year renewal period and conveys rights to the lessee to perform drilling and operating activities for producing oil, natural gas or other hydrocarbons. As part of the lease agreement, the third party agreed to pay us the sum of $6,000 per acre as a lease bonus, of which $500,000 was paid at the signing of the lease agreement. The remainder of the lease bonus payment will be paid by the third party to us within 90 days from the date the lease agreement was signed. In addition, the lease agreement stipulates that the third party shall pay us a 20% royalty based upon the gross proceeds received from the sale of oil and/or natural gas recovered from the leased property.

Sale of Mining Assets

In February 2012, the Partnership sold certain non-core mining assets located in Pike County, Kentucky to a third party for approximately $0.6 million. The transaction also extinguished certain liabilities related to the assets sold. In relation to the sale of these assets and

26

extinguishment of liabilities, we recorded a gain of approximately $0.9 million, which was higher than the sales amount due to the extinguishment of the liabilities.

In August 2011, we sold and assigned certain non-core mining assets and related liabilities located in the Phelps, Kentucky area of our Tug River mining complex for approximately $20 million. The mining assets included leasehold interests and permits to surface and mineral interests that included steam coal reserves and non-reserve coal deposits. Additionally, the sales agreement includes the potential for additional payments of approximately $8.75 million dependent upon the future issuance of certain permits and the commencement of mining activities by the purchaser. These contingent payments are being accounted for as gain contingencies and will be recognized in the future when and if the contingencies are resolved. The transaction also transferred certain liabilities related to the assets sold that we believe will positively impact future cash flows. Since we had limited mining operations on the assets that were sold, we believe the sale of these assets will not have a negative impact on our future financial results. In relation to the sale of these assets and transfer of liabilities, we recorded a gain of approximately $2.4 million.

Follow-on Offering

On July 18, 2011, we completed a public offering of 2,875,000 common units, representing limited partner interests in us, at a price of $24.50 per common unit. Of the common units issued, 375,000 units were issued in connection with the exercise of the underwriters’ option to purchase additional units. Net proceeds from the offering were approximately $66.4 million, after deducting underwriting discounts and offering expenses of approximately $4.1 million. We used the net proceeds from this offering, and a related capital contribution by our general partner of approximately $1.4 million, to repay approximately $67.8 million of outstanding indebtedness under our credit facility.

Credit Facility

On July 29, 2011, we executed an amended and restated senior secured credit facility with PNC Bank, N.A., as administrative agent, and a group of lenders, which are parties thereto. The maximum availability under the amended and restated credit facility is $300.0 million, with a one-time option to increase the availability by an amount not to exceed $50.0 million.

The original maximum availability under our credit facility with PNC Bank, N.A. as administrative agent, was $200.0 million. On June 8, 2011, with the consent of the lenders, we exercised the option to increase the amount available to borrow under the credit agreement by $50.0 million to $250.0 million as part of the Elk Horn acquisition.

Proposed Carbon Emission Rules

On March 27, 2012, the Environmental Protection Agency (“EPA”) proposed New Source Performance Standards (“NSPS”) for carbon dioxide emissions from new and modified electric power.  The proposed NSPS, if promulgated along the lines proposed, would pose significant challenges for the construction of new coal-fired power plants and could result in a decrease in U.S. demand for steam coal.

Factors That Impact Our Business

Our results of operations in the near term could be impacted by a number of factors, including (1) adverse weather conditions and natural disasters, (2) poor mining conditions resulting from geological conditions or the effects of prior mining, (3) equipment problems at mining locations, (4) the availability of transportation for coal shipments or (5) the availability and costs of key supplies and commodities such as steel, diesel fuel and explosives.

On a long-term basis, our results of operations could be impacted by, among other factors, (1) changes in governmental regulation, (2) the availability and prices of competing electricity-generation fuels, (3) our ability to secure or acquire high-quality coal reserves and (4) our ability to find buyers for coal under favorable supply contracts.

Most often our coal is sold through supply contracts and we anticipate that we will continue to do so. As of March 31, 2012, we had commitments under sales contracts to deliver annually scheduled base quantities of approximately 3.9 million, approximately 3.5 million, approximately 2.0 million and approximately 0.3 million tons of coal to 16 customers in 2012, 7 customers in 2013, 4 customers in 2014 and 1 customers in 2015, respectively. Some of the contracts have sales price adjustment provisions, subject to certain limitations and adjustments, based on a variety of factors and indices.

We received a notice from one of our major customers in early April 2012 announcing it would be delaying some of its contracted steam coal shipments from our Central Appalachia and Northern Appalachia operations for an undefined period of time due to an over-supply of coal at its locations.  While this customer has acknowledged its contractual obligation, we are working with this customer to schedule its contracted steam coal purchases and this customer has recently taken limited shipments from our operations.  Substantial uncertainty remains as to the impact on us and our results of operations of future decisions by this major customer regarding its delayed shipments.

Results of Operations

Segment Information

We conduct business through four reportable business segments: Central Appalachia, Northern Appalachia, Eastern Met and Rhino Western. Additionally, we have an Other category that includes our ancillary businesses. Our Central Appalachia segment consists of three mining complexes: Tug River, Rob Fork and Deane, which are located in eastern Kentucky and southern West Virginia. Additionally, our Central Appalachia segment includes the Elk Horn operations. Our Northern Appalachia segment consists of the Hopedale mining complex, the Sands Hill mining complex, the Leesville field and the Springdale field. The Hopedale mining complex, located in northern Ohio, included one underground mine and one preparation plant and loadout facility as of March 31, 2012. Our Sands Hill mining complex, located in southern Ohio, included two surface mines, a preparation plant and a river terminal as of March 31, 2012. Our Rhino Western segment includes our two underground mines in the Western Bituminous region that consist of our McClane Canyon mine in Colorado that has been temporarily idled since the end of 2010, and remained idle at March 31, 2012, and our Castle Valley mining complex in

28

Utah that began production in January 2011. The Eastern Met segment includes our 51% equity interest in the results of operations of the Rhino Eastern joint venture, which owns the Rhino Eastern mining complex, located in West Virginia, and for which we serve as manager. As of March 31, 2012, this complex was comprised of two underground mines and a preparation plant and loadout facility (owned by our joint venture partner). Our Other category includes our ancillary businesses that consist of a roof bolt manufacturing operation, limestone operations and various businesses that provide support services such as reclamation, maintenance and transportation, the cost of which is reflected in our cost of operations.

Evaluating Our Results of Operations

Our management uses a variety of financial measurements to analyze our performance, including (1) Adjusted EBITDA, (2) coal revenues per ton and (3) cost of operations per ton.

Adjusted EBITDA.  The discussion of our results of operations below includes references to, and analysis of, our segments’ Adjusted EBITDA results. Adjusted EBITDA represents net income before deducting interest expense, income taxes and depreciation, depletion and amortization, including our proportionate share of these expense items from our Rhino Eastern LLC joint venture, while also excluding certain non-recurring items. Adjusted EBITDA is used by management primarily as a measure of our segments’ operating performance. Adjusted EBITDA should not be considered an alternative to net income, income from operations, cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Because not all companies calculate Adjusted EBITDA identically, our calculation may not be comparable to similarly titled measures of other companies. Please read “—Reconciliation of Adjusted EBITDA to Net Income by Segment” for reconciliations of Adjusted EBITDA to net income by segment for each of the periods indicated.

Coal Revenues Per Ton.  Coal revenues per ton represents coal revenues divided by tons of coal sold. Coal revenues per ton is a key indicator of our effectiveness in obtaining favorable prices for our product.

Cost of Operations Per Ton.  Cost of operations per ton sold represents the cost of operations (exclusive of depreciation, depletion and amortization) divided by tons of coal sold. Management uses this measurement as a key indicator of the efficiency of operations.

Three Months Ended March 31, 2012 Compared to Three Months Ended March 31, 2011

Summary.  For the three months ended March 31, 2012, our total revenues decreased to $81.9 million from $82.8 million for the three months ended March 31, 2011. We sold 1.1 million tons of coal for the three months ended March 31, 2012, which is a 4.5% decrease compared to the tons of coal sold for the three months ended March 31, 2011. This decrease was the result of weak demand in the met and steam coal markets as well as delays in customer contracted shipments. We believe the weak demand in the coal markets was primarily driven by an unseasonably mild winter along with an over-supply of low priced natural gas, both of which resulted in fewer tons of steam coal being utilized in electricity generation.

For the three months ended March 31, 2012, we increased our coal inventories by approximately 0.2 million tons. Our coal inventory increased in the first quarter of 2012 due to

30

weak demand in the steam and met coal markets as well as delays in customer contracted shipments.

Net income and Adjusted EBITDA increased for the three months ended March 31, 2012 from the three months ended March 31, 2011.  Net income was approximately $9.0 million for the three months ended March 31, 2012 compared to approximately $6.1 million for the three months ended March 31, 2011 as reductions in costs and expenses were partially offset by lower revenues. Net income was also positively impacted period to period due to $2.1 million of income from our Rhino Eastern joint venture for the three months ended March 31, 2012 compared to income of $0.7 million for the three months ended March 31, 2011, which represents our proportionate share of income from the joint venture in which we have a 51% membership interest and for which we serve as manager.

Adjusted EBITDA increased to $22.2 million for the three months ended March 31, 2012 from $16.7 million for the three months ended March 31, 2011. Adjusted EBITDA increased period to period due to an increase in net income, as well as a higher amount added back to net income for depreciation, depletion and amortization expense and a slight increase in interest expense. Adjusted EBITDA was also positively impacted period to period due to the net income impact from our Rhino Eastern joint venture discussed above.

Tons Sold.  The following table presents tons of coal sold by reportable segment for the three months ended March 31, 2012 and 2011:

	Three months	Three months	Increase/

*Calculated percentages and the rounded totals presented are based upon on actual whole ton amounts and not the rounded amounts presented in this table.

†Excludes tons sold by the joint venture, which owns the Rhino Eastern mining complex located in West Virginia and for which we serve as manager.

We sold approximately 1,069,000 tons of coal for the three months ended March 31, 2012 compared to approximately 1,120,000 tons for the three months ended March 31, 2011. The slight decrease in total tons sold year-to-year was primarily due to weakness in the met and steam coal markets, primarily in Central Appalachia, along with delays in customer contracted shipments, partially offset by increased sales at our Castle Valley operation in Utah. Tons of coal sold in our Central Appalachia segment decreased by approximately 180,000 tons, or 32.3%, to approximately 377,000 tons for the three months ended March 31, 2012 from approximately

31

557,000 tons for the three months ended March 31, 2011. For our Northern Appalachia segment, tons of coal sold decreased by approximately 56,000 tons, or 11.0%, to approximately 448,000 tons for the three months ended March 31, 2012 from approximately 504,000 tons for the three months ended March 31, 2011. Coal sales from our Rhino Western segment increased by approximately 185,000 tons, or 313.7%, for the three months ended March 31, 2012 compared to approximately 59,000 million tons for the three months ended March 31, 2011.

*Percentages and per ton amounts are calculated based on actual amounts and not the rounded amounts presented in this table.

**The Other category includes results for our ancillary businesses. The activities performed by these ancillary businesses do not directly relate to coal production. As a result, coal revenues and coal revenues per ton are not presented for this category.

Our coal revenues for the three months ended March 31, 2012 decreased by approximately $9.0 million, or 11.4%, to approximately $69.6 million from approximately $78.6 million for the three months ended March 31, 2011. The decrease in coal revenues was primarily due to weakness in the met and steam coal markets, primarily in Central Appalachia, along with delays in customer contracted shipments. Coal revenues per ton were $65.11 for the three months ended March 31, 2012, a decrease of $5.06, or 7.2%, from $70.17 per ton for the three months ended March 31, 2011. This decrease in coal revenues per ton was primarily the result of a higher mix of lower priced coal from our Rhino Western operations.

For our Central Appalachia segment, coal revenues decreased by approximately $14.6 million, or 29.4%, to approximately $34.9 million for the three months ended March 31, 2012 from approximately $49.5 million for the three months ended March 31, 2011 primarily due to weakness in the met and steam coal markets, along with delays in customer contracted shipments, which resulted in fewer tons sold. Coal revenues per ton for our Central Appalachia segment increased by $3.74, or 4.2%, to $92.47 per ton for the three months ended March 31, 2012 as compared to $88.73 for the three months ended March 31, 2011, due to higher contracted prices, primarily related to metallurgical coal sold. Other revenues increased for our Central Appalachia segment primarily due to coal royalty revenue from Elk Horn.

For our Northern Appalachia segment, coal revenues were approximately $24.7 million for the three months ended March 31, 2012, a decrease of approximately $2.1 million, or 7.8%, from approximately $26.8 million for the three months ended March 31, 2011. This decrease was due to delays in customer shipments due to weakness in the steam coal market, which resulted in fewer tons sold. Coal revenues per ton for our Northern Appalachia segment increased by $1.91, or 3.6%, to $55.14 per ton for the three months ended March 31, 2012 as compared to $53.23 per ton for the three months ended March 31, 2011. This increase was primarily due to higher contracted prices for steam coal.

For our Rhino Western segment, coal revenues increased by approximately $7.7 million, or 330.0%, to approximately $10.0 million for the three months ended March 31, 2012 from approximately $2.3 million for the three months ended March 31, 2011. Coal revenues per ton for our Rhino Western segment were $41.07 for the three months ended March 31, 2012, an increase of $1.56, or 4.0%, from $39.51 for the three months ended March 31, 2011. The increases in revenue and coal revenues per ton were due to increased sales and higher selling prices to customers for coal produced at our Castle Valley mine.

Other revenues for our Other category were flat period to period at $1.6 million.

** Cost of operations presented for our Other category includes costs incurred by our ancillary businesses. The activities performed by these ancillary businesses do not directly relate to coal production. As a result, per ton measurements are not presented for this category.

Cost of Operations.  Total cost of operations was $57.1 million for the three months ended March 31, 2012 as compared to $61.1 million for the three months ended March 31, 2011. Our cost of operations per ton was $53.41 for the three months ended March 31, 2012, a decrease of $1.12, or 2.1%, from the three months ended March 31, 2011. These overall decreases in the cost of operations and cost of operations on a per ton basis were primarily due to a higher mix of lower cost tons from our Castle Valley mine, decreased production due to weakness in the met and steam coal markets, primarily in Central Appalachia, as well as focusing production at more cost efficient operations.

Our cost of operations for the Central Appalachia segment decreased by $10.2 million, or 28.7%, to $25.3 million for the three months ended March 31, 2012 from $35.5 million for the three months ended March 31, 2011. Our cost of operations per ton increased to $67.14 per ton for the three months ended March 31, 2012 from $63.81 per ton for three months ended March 31, 2011. The decrease in total cost of operations was primarily due to decreased production in response to weakness in the met and steam coal markets. Cost of operations per ton increased since a portion of our costs are fixed in nature and these fixed costs were spread over a smaller number of tons sold in the three months ended March 31, 2012.

In our Northern Appalachia segment, our cost of operations increased by $1.6 million, or 8.9%, to $19.2 million for the three months ended March 31, 2012 from $17.6 million for the three months ended March 31, 2011. Our cost of operations per ton was $42.80 for the three months ended March 31, 2012, an increase of $7.83, or 22.4%, compared to $34.97 for the three months ended March 31, 2011. The increases in cost of operations and cost of operations per ton were primarily due to geology issues of mining thinner coal seams at our Hopedale mine and an equipment issue that resulted in the need to replace a mining shovel at one of our Sands Hill surface mines.

Our cost of operations for the Rhino Western segment increased by $4.4 million, or 179.5%, to $6.9 million for the three months ended March 31, 2012 from $2.5 million for the three months ended March 31, 2011. Our cost of operations per ton decreased to $28.16 per ton for the three months ended March 31, 2012 from $41.67 per ton for three months ended March 31, 2011. The increase in cost of operations was primarily due to increased production at our Castle Valley mine. Cost of operations per ton decreased primarily due to our Castle Valley mine being at full production in the first quarter of 2012 compared to costs incurred in the first quarter of 2011 associated with preparing our Castle Valley mine to begin production that had a small amount of tons sold.

Cost of operations in our Other category increased slightly by $0.2 million for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011. This increase was primarily due to an increase in amounts spent for professional fees and outside services.

Freight and Handling.  Total freight and handling cost for the three months ended March 31, 2012 increased by $0.5 million, or 55.5%, to $1.3 million from $0.8 million for the

36

three months ended March 31, 2011. This increase was primarily due to an increase in the tons of limestone sold for the three months ended March 31, 2012 as compared to the three months ended March 31, 2011, as well as an increase in diesel fuel prices.

Depreciation, Depletion and Amortization.  Total depreciation, depletion and amortization, or DD&A, expense for the three months ended March 31, 2012 was $11.1 million as compared to $9.1 million for the three months ended March 31, 2011.

For the three months ended March 31, 2012, our depreciation cost was $8.8 million as compared to $6.7 million for the three months ended March 31, 2011. This increase is primarily due to an increase in machinery and equipment, including a new high-wall miner purchased in Central Appalachia.

For the three months ended March 31, 2012, our depletion cost was $1.5 million compared to $0.9 million for the three months ended March 31, 2011. This increase is primarily attributable to depletion expense incurred at our Elk Horn operations that were not present in the 2011 comparable period since Elk Horn was acquired in June 2011.

For the three months ended March 31, 2012, our amortization cost was $0.8 million as compared to $1.5 million for the three months ended March 31, 2011. This decrease is primarily attributable to changes in asset retirement costs based on revisions to reserve valuations and useful lives.

Selling, General and Administrative.  Selling, general and administrative, or SG&A, expense for the three months ended March 31, 2012 was $4.9 million as compared to $5.4 million for the three months ended March 31, 2011. This decrease in SG&A expense was primarily due to a decrease in expenditures for legal fees and other professional fees.

Interest Expense.  Interest expense for the three months ended March 31, 2012 was $1.8 million as compared to $1.1 million for the three months ended March 31, 2011, an increase of $0.7 million, or 72.2%. This increase was primarily the result of an increase in the balance due under our credit facility.

Eastern Met Supplemental Data.  Operational and financial data for the Rhino Eastern joint venture in which we have a 51% membership interest and for which we serve as manager (referred to as the “Eastern Met” segment) is presented below. Our consolidated revenue and costs do not include any portion of the revenue or costs of Rhino Eastern since we account for this operation under the equity method. We only record our proportionate share of net income of Rhino Eastern as a single item in our financial statements, but we believe the presentation of these items for Rhino Eastern provides additional insight into how this operation contributes to our overall performance.

Rhino Eastern’s Eagle #2 mine began production in the third quarter of 2011, which resulted in an increase in tons produced and sold for the three months ended March 31, 2012 compared to 2011. The increase in tons sold as well as higher contracted sales prices resulted in increased revenue and net income for the three months ended March 31, 2012 compared to the same period in 2011.

Net Income (Loss).  The following table presents net income (loss) by reportable segment for the three months ended March 31, 2012 and 2011:

For the three months ended March 31, 2012, total net income increased to approximately $9.0 million compared to approximately $6.1 million the three months ended March 31, 2011 as decreases in costs and expenses were partially offset by decreases in coal revenues. For our Central Appalachia segment, net income increased to $2.4 million for the three months ended March 31, 2012, an increase of $0.3 million as compared to the three months ended March 31, 2011, primarily due to a reduction in cost of operations. Net income in our Northern Appalachia segment decreased by $1.3 million to $5.0 million for the three months ended March 31, 2012, from $6.3 million for the three months ended March 31, 2011. This decrease was primarily the result of a decrease in tons of coal sold due to delays in customer shipments of contracted steam coal. Net income in our Rhino Western segment increased by $2.6 million to income of $1.4 million for the three months ended March 31, 2012, compared to a loss of $1.2 million for the three months ended March 31, 2011. This increase was primarily the result of increased tons sold at our Castle Valley operation. Our Eastern Met segment recorded net income of $2.1 million for the three months ended March 31, 2012, an increase of $1.4 million from net income of $0.7 million for the three months ended March 31, 2011.  For the Other category, we had a net loss of $1.9 million for the three months ended March 31, 2012, which was relatively flat as compared to a net loss of $1.8 million for the three months ended March 31, 2011.

Adjusted EBITDA.  The following table presents Adjusted EBITDA by reportable segment for the three months ended March 31, 2012 and 2011:

*Includes our 51% equity interest in the results of the joint venture, which owns the Rhino Eastern mining complex located in West Virginia and for which we serve as manager.

Total Adjusted EBITDA for the three months ended March 31, 2012 was $22.2 million, an increase of $5.5 million from the three months ended March 31, 2011. Adjusted EBITDA increased as a result of an increase in net income, as well as a higher amount added back to net income for depreciation, depletion and amortization expense and a slight increase in interest expense. Results of operations from our Eastern Met segment are recorded using the equity method and are reflected as a single line item in our financial statements. Therefore, DD&A and interest expense are not presented separately for our Eastern Met segment. Please read “—

Liquidity and Capital Resources

Liquidity

Our business is capital intensive and requires substantial capital expenditures for purchasing, upgrading and maintaining equipment used in developing and mining our reserves, as well as complying with applicable environmental and mine safety laws and regulations. Our principal liquidity requirements are to finance current operations, fund capital expenditures, including acquisitions from time to time, and service our debt. Our sources of liquidity include cash generated by our operations, borrowings under our credit agreement and issuances of equity and debt securities.

The principal indicators of our liquidity are our cash on hand and availability under our credit agreement. As of March 31, 2012, our available liquidity was $112.3 million, including cash on hand of $0.6 million and $111.7 million available under our credit agreement.

Please read “—Capital Expenditures” for a further discussion of the impact on liquidity.

41

Cash Flows

Net cash provided by operating activities was $17.1 million for the three months ended March 31, 2012 as compared to $6.0 million for the three months ended March 31, 2011.  This increase in cash provided by operating activities was primarily the result of a favorable change in accounts receivable period to period, which is due to the timing of sales in the later part of the quarter in 2011 compared to 2012. The favorable change in accounts receivable was partially offset by an unfavorable change in inventories that resulted from an increase in coal inventories in the first quarter of 2012 due to weakness in the coal markets, especially steam coal.

Net cash used in investing activities was $27.3 million for the three months ended March 31, 2012 as compared to $6.9 million for the three months ended March 31, 2011.  The increase in cash used in investing activities was primarily due to the increased amounts expended for the purchase of mining equipment and other asset acquisitions, primarily related to the new preparation plant in our Tug River mining complex.

Net cash provided by financing activities for the three months ended March 31, 2012 was $10.3 million, which was primarily attributable to borrowings under our credit agreement, partially offset by our distributions to unitholders in the first quarter of 2012.  Net cash provided by financing activities for the three months ended March 31, 2011 was $1.8 million, which were primarily attributable to borrowings under our credit agreement, partially offset by our distributions to unitholders in the first quarter of 2011.

Capital Expenditures

Our mining operations require investments to expand, upgrade or enhance existing operations and to meet environmental and safety regulations. Maintenance capital expenditures are those capital expenditures required to maintain our long-term operating capacity. Examples of maintenance capital expenditures include expenditures associated with the replacement of equipment and coal reserves, whether through the expansion of an existing mine or the acquisition or development of new reserves to the extent such expenditures are made to maintain our long-term operating capacity. Expansion capital expenditures are those capital expenditures that we expect will increase our operating capacity over the long term. Examples of expansion capital expenditures include the acquisition of reserves, equipment for a new mine or the expansion of an existing mine to the extent such expenditures are expected to expand our long-term operating capacity.

Actual maintenance capital expenditures for the three months ended March 31, 2012 were approximately $7.8 million. These amounts were primarily used to rebuild, repair or replace older mining equipment. Expansion capital expenditures for the three months ended March 31, 2012 were approximately $17.6 million, which were primarily related to the new preparation plant in our Tug River mining complex. For the year ending December 31, 2012, we have budgeted $15.0 million to $18.0 million for maintenance capital expenditures.

We believe that we have sufficient liquid assets, cash flows from operations and borrowing capacity under our credit agreement to meet our financial commitments, debt service obligations, contingencies and anticipated capital expenditures for the next twelve months. However, we are subject to business and operational risks that could adversely affect our cash

42

flow. A material decrease in our cash flows would likely produce a corollary adverse effect on our borrowing capacity. From time to time, we may issue debt and equity securities.

Credit Agreement

The original maximum availability under our credit facility with PNC Bank, N.A. as administrative agent, was $200.0 million. On June 8, 2011, with the consent of the lenders, we exercised the option to increase the amount available to borrow under the credit agreement by $50.0 million to $250.0 million as part of the Elk Horn acquisition.

On July 29, 2011, we executed an amended and restated senior secured credit facility with PNC Bank, N.A., as administrative agent, and a group of participating lenders. The maximum availability under the amended and restated credit facility is $300.0 million, with a one-time option to increase the availability by an amount not to exceed $50.0 million. Of the $300.0 million, $75.0 million is available for letters of credit.

Loans under the credit agreement bear interest at either (i) a base rate equaling the highest of (a) the Federal Funds Open Rate plus 0.50%; (b) the prime rate; or (c) daily LIBOR plus 1.00%, plus an applicable margin in each case or (ii) LIBOR plus an applicable margin, at our option. The applicable margin for the base rate option is 1.50% to 2.25%, and the applicable margin for the LIBOR option is 2.50% to 3.25%, each of which depends on our and our subsidiaries’ consolidated leverage ratio (“Consolidated Leverage Ratio”). The credit agreement also contains letter of credit fees equal to an applicable margin of 2.50% to 3.25% depending on the Consolidated Leverage Ratio, multiplied by the aggregate amount available to be drawn on the letters of credit, and a 0.15% fronting fee payable to the administrative agent. In addition, we incur a commitment fee on the unused portion of the credit agreement at a rate of 0.375% to 0.50% per annum, depending on the Consolidated Leverage Ratio. Borrowings on the line of credit are collateralized by all of our unsecured assets.

Our credit agreement requires us to maintain certain minimum financial ratios and contains certain restrictive provisions, including among others, restrictions on making loans, investments and advances, incurring additional indebtedness, guaranteeing indebtedness, creating liens, and selling or assigning stock. As of and for the three months ended March 31, 2012, we were in compliance with respect to all covenants contained in the credit agreement. The credit agreement expires in July 2016.

At March 31, 2012, we had borrowed $155.0 million at a variable interest rate of LIBOR plus 2.75% (3.00% at March 31, 2012) and an additional $6.6 million at a variable interest rate of PRIME plus 2.00% (5.00% at March 31, 2012). In addition, we had outstanding letters of credit of approximately $26.8 million at a fixed interest rate of 2.75% at March 31, 2012. We had not used $111.7 million of the borrowing availability at March 31, 2012. During the three months ended March 31, 2012, we had average borrowings outstanding of approximately $148.4 million in relation to this credit agreement.

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to certain off-balance sheet arrangements. These arrangements include guarantees and financial instruments with off-balance sheet risk, such as bank letters of credit and surety bonds. No liabilities related to these

43

arrangements are reflected in our consolidated balance sheet, and we do not expect any material adverse effects on our financial condition, results of operations or cash flows to result from these off-balance sheet arrangements.

Federal and state laws require us to secure certain long-term obligations related to mine closure and reclamation costs. We typically secure these obligations by using surety bonds, an off-balance sheet instrument. The use of surety bonds is less expensive for us than the alternative of posting a 100% cash bond or a bank letter of credit, either of which would require a greater use of our credit agreement. We then use bank letters of credit to secure our surety bonding obligations as a lower cost alternative than securing those bonds with a committed bonding facility pursuant to which we are required to provide bank letters of credit in an amount of up to 25% of the aggregate bond liability. To the extent that surety bonds become unavailable, we would seek to secure our reclamation obligations with letters of credit, cash deposits or other suitable forms of collateral.

As of March 31, 2012, we had $26.8 million in letters of credit outstanding, of which $21.8 million served as collateral for surety bonds.

Critical Accounting Policies and Estimates

Our financial statements are prepared in accordance with accounting principles that are generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities. Management evaluates its estimates and judgments on an on-going basis. Management bases its estimates and judgments on historical experience and other factors that are believed to be reasonable under the circumstances. Nevertheless, actual results may differ from the estimates used and judgments made.

The accounting policies and estimates that we have adopted and followed in the preparation of our consolidated financial statements are fully described in our Annual Report on Form 10-K for the year ended December 31, 2011. There have been no significant changes in these policies and estimates as of March 31, 2012.

Recent Accounting Pronouncements

In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”. This ASU changes certain fair value measurement principles and clarifies the application of existing fair value measurement guidance. Amendments included in this ASU clarify the intent about the application of existing fair value measurement including the application of the highest and best use and valuation premise concepts. The amendments in this ASU specify that the concepts of highest and best use and valuation premise in a fair value measurement are relevant only when measuring the fair value of nonfinancial assets and are not relevant when measuring the fair value of financial assets or of liabilities. This ASU also requires additional fair value disclosures including a qualitative discussion about the sensitivity of recurring Level 3 fair value measurements and the categorization by level of the fair value

44

hierarchy for items that are not measured at fair value in the statement of financial position, but for which the fair value is required to be disclosed. The ASU is effective for interim and annual periods beginning after December 15, 2011 and are to be applied prospectively. While this ASU does not have an impact on our financial results, we will have additional disclosures in the notes to our financial statements.

In September 2011, the FASB published ASU No. 2011-08, “Intangibles—Goodwill and Other (Topic 350) Testing Goodwill for Impairment”. Under the amendments in this ASU, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step goodwill impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if any. Under the amendments in this ASU, an entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 and early adoption is permitted. We do not believe this new accounting guidance will have a material effect on our financial results.

In June 2011, the FASB published ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”. Under the amendments in this ASU, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. In a single continuous statement, the entity is required to present the components of net income and total net income, the components of other comprehensive income and a total for other comprehensive income, along with the total of comprehensive income in that statement. In the two-statement approach, an entity is required to present components of net income and total net income in the statement of net income. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive income. Regardless of whether an entity chooses to present comprehensive income in a single continuous statement or in two separate but consecutive statements, the entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The amendments in this ASU do not

45

change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The amendments do not change the option for an entity to present components of other comprehensive income either net of related tax effects or before related tax effects, with one amount shown for the aggregate income tax expense or benefit related to the total of other comprehensive income items. In both cases, the tax effect for each component must be disclosed in the notes to the financial statements or presented in the statement in which other comprehensive income is presented. The amendments do not affect how earnings per share is calculated or presented. For public entities, the amendments of this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011.

Subsequently, in December 2011, the FASB issued ASU No. 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”. In order to defer only those changes in Update 2011-05 that relate to the presentation of reclassification adjustments, the paragraphs in this ASU supersede certain pending paragraphs in ASU 2011-05. The amendments are being made to allow the FASB time to re-deliberate whether to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. While the FASB is considering the operational concerns about the presentation requirements for reclassification adjustments and the needs of financial statement users for additional information about reclassification adjustments, entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect before ASU 2011-05. All other requirements in ASU 2011-05 are not affected by this ASU 2011-12, including the requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements. Public entities should apply these requirements for fiscal years, and interim periods within those years, beginning after December 15, 2011. We have consistently presented comprehensive income in a single continuous statement with net income, so the provisions of ASU 2011-05 and the related deferral included in ASU 2011-12 did not have a material effect on us.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. The principal market risks to which we are exposed are commodity risk and interest rate risk.

Commodity Price Risk

We manage our commodity price risk for coal sales through the use of supply contracts and the use of forward contracts.

Some of the products used in our mining activities, such as diesel fuel, explosives and steel products for roof support used in our underground mining, are subject to price volatility. Through our suppliers, we utilize forward purchases to manage the exposure related to this volatility. A hypothetical increase of $0.10 per gallon for diesel fuel would have reduced net

46

income by $0.2 million for the three months ended March 31, 2012. A hypothetical increase of 10% in steel prices would have reduced net income by $0.4 million for the three months ended March 31, 2012. A hypothetical increase of 10% in explosives prices would have reduced net income by $0.2 million for the three months ended March 31, 2012.

Interest Rate Risk

We have exposure to changes in interest rates on our indebtedness associated with our credit agreement. During the past year, we have been operating in a period of declining interest rates, and we have managed to take advantage of the trend to reduce our interest expense. A hypothetical increase or decrease in interest rates by 1% would have changed our interest expense by $0.4 million for the three months ended March 31, 2012.

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures.  As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of March 31, 2012 at the reasonable assurance level.

Changes in Internal Control over Financial Reporting.  There was no change in our internal control over financial reporting that occurred during the quarter ended March 31, 2012, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1.Legal Proceedings.

We may, from time to time, be involved in various legal proceedings and claims arising out of our operations in the normal course of business.  While many of these matters involve inherent uncertainty, we do not believe that we are a party to any legal proceedings or claims that will have a material adverse impact on our business, financial condition or results of operations.

Item 1A.  Risk Factors.

In addition to the other information set forth in this Report, you should carefully consider the risks under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011, which risks could materially affect our business, financial condition or future results. There has been no material change in our risk factors from those described in the Annual Report on Form 10-K for the year ended December 31, 2011. These risks are not the only risks that we face.  Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or results of operations.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds.

There were no sales of unregistered equity securities during the period covered by this report.
