Explanatory Note

Alliance Resource Partners, L.P. ("we," "us," or "our") is filing this Amendment No. 1 on Form 10-K/A ("Amended Filing") in order to amend our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, originally filed on February 25, 2022 ("Original Filing"), to provide amended disclosures pursuant to correspondence with the staff (the “Staff”) of the Securities and Exchange Commission ("SEC") in connection with the Staff’s review of new property disclosure requirements for publicly traded mining companies recently implemented by the SEC and reflected in our Original Filing for the first time. The following items were impacted by these amended disclosures and are hereby amended and restated in their entirety:

Part I. Item 2. Properties – We (i) modified the disclosure of the coal pricing assumptions used by RESPEC in estimating the amount of coal mineral resources and reserves to provide the range of prices used for each coal basin or market region along with an explanation as to why different pricing ranges were used for estimating the Illinois Basin resources and reserves, (ii) added clarification that the estimates of coal mineral resources and reserves between the Henderson-Union and River View properties are distinct and separate despite their geographic overlap, and (iii) added explanations for the absence of mineral resource estimates for certain individual property disclosures.
Part IV. Item 15. Exhibits and Financial Statement Schedules – We amended our technical report summaries contained in exhibits 96.1, 96.2, 96.3, 96.4 and 96.5 to address various requests by the SEC.

We are also including currently dated certifications by our Chief Executive Officer and Chief Financial Officer as Exhibits 31.3 and 31.4 under Section 302 of the Sarbanes-Oxley Act of 2002, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended.

Other than as expressly set forth above and except with respect to certain conforming changes made to our exhibit index, this Amended Filing does not, and does not purport to, update or restate the information in the Original Filing or reflect any events that have occurred after the Original Filing. Moreover, the information included in this Amended Filing does not update or otherwise affect the financial statements filed as part of the Original Filing. This Amended Filing should be read in conjunction with the Original Filing and our other filings with the SEC.

ITEM 2.PROPERTIES

Coal Mineral Resources and Reserves

Overview of Coal Properties

Our coal properties are located in the Illinois Basin and the Appalachia Basin. Our Illinois Basin properties are located in western Kentucky, southern Illinois, and southern Indiana. Our Appalachian properties are located in eastern Kentucky, Maryland, western Pennsylvania, and northern West Virginia. Mining operations on our coal properties consist of underground mines that produce bituminous coal that is sold to customers principally for electric power generation (thermal) and the production of steel (metallurgical).  In addition to our coal mining operations, we also hold coal mineral interests that we lease/sublease to our operations or hold for lease/sublease to our operations or others. For a detailed overview of our coal mining operations and our coal royalty activities, please see "Item 1. Business—Coal Mining Operations" and "Item 1. Business—Mineral Interest Activities", respectively.

Evaluation and Review of Coal Mineral Resources and Reserves

Numerous uncertainties are inherent in estimating coal mineral resources and reserves, and the estimates are subject to change as additional information becomes available or circumstances change.  Significant factors and assumptions related to the uncertainty in estimating coal mineral reserves and resources include:

geological and mining conditions, which may not be fully identified by available exploration data and/or differ from our experiences in areas where we currently mine;
the percentage of coal in the ground ultimately recoverable;
historical production from the area compared with production from other producing areas;
the assumed effects of regulation and taxes by governmental agencies;
future improvements in mining technology; and
assumptions concerning future coal prices, operating costs, capital expenditures, severance and excise taxes, and development and reclamation costs.

Each of the factors which impacts reserve and resource estimation may vary considerably from the assumptions used in making the estimation and, as a result, the estimates in this report may not accurately reflect the actual coal reserves and resources.  Actual production, revenues and expenditures with respect to the coal reserves will likely vary from the assumptions used in these estimates, and these variances may be material.  Government regulations and other pressures may result in closure of coal-fired electric generating plants earlier than assumed.  Such changes would reduce the economic viability of our mining operations and could have a material adverse impact on our operations and financial results. Additionally, the estimates of coal reserves and resources may be adversely affected in future fiscal periods by the SEC's recent rule amendments revising property disclosure requirements for publicly traded coal mining companies, with which we are complying for the first time in this report.

Under SEC rules, a mineral resource is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable.  A mineral reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.  

The coal mineral resource and reserve estimates included in this Annual Report on Form 10-K were prepared by an independent, qualified engineering firm, RESPEC Company, LLC ("RESPEC").  We provided RESPEC with property control, mine plans, production, revenue, costs, capital, and other information considered by RESPEC in making their

estimates.  As part of our internal controls, our geologists and engineers review the integrity, accuracy, and timeliness of the data provided to RESPEC that they considered in calculating their coal mineral resource and reserve estimates.  We also review the geologic data, mining assumptions, and methodology used by RESPEC to estimate our coal mineral resources and reserves.  Our geologists and engineers also met with RESPEC periodically during the year to discuss the assumptions and methods used in the coal mineral resource and reserve estimation process.

RESPEC, an independent third-party engineering firm, does not own an interest in any of our properties and is not employed on a contingent basis. RESPEC's Technical Report Summaries for each of our material mining operations are included as exhibits to this Annual Report on Form 10-K.

Summary of Coal Mineral Resources and Reserves

Coal Mineral Resources

Most of our coal properties designated as mineral resources are of thickness, quality, and mineability similar to that of the mineral reserves, and all are proximal to existing infrastructure such as power, water, transportation, facilities, etc.  However, we have not completed pre-feasibility or feasibility studies with respect to our coal properties designated as mineral resources, as is required to convert the mineral resources into mineral reserves. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves.

(1)Combined resources are defined as measured plus indicated resources.

At December 31, 2021, we had approximately 1.165 billion tons of coal mineral resources.  Tonnages are reported on a clean recoverable basis with pricing based on available third-party forecasts and historical pricing adjusted for quality at the end of 2021 in a range from $36.27 to $51.26 per short ton in the Illinois Basin and from $42.68 to $66.27 per short ton in the Appalachian Basin, which are the prices used by RESPEC to estimate the amount of coal mineral resources. All resources are classified as underground mineable in the exploration stage.    

Coal sales prices vary based on coal quality, access to transportation, and other factors at each location.  In the Illinois Basin, we have coal resources that are not associated with coal reserves and have different factors affecting the coal sales price.  In addition, we have coal reserves that do not have associated coal resources.  As a result, the Illinois Basin resources and the Illinois Basin reserves have different price ranges.

Coal Mineral Reserves

Reserves are assigned to our active operations and are (1) currently in production, (2) economically viable, and (3) meet the other requirements to be considered reserves as defined by the SEC.

On December 31, 2021, we had approximately 547.1 million tons of coal mineral reserves.  Tonnages are reported on a clean recoverable basis with pricing based on available third-party forecasts and historical pricing adjusted for quality at the end of 2021 in a range from $36.08 to $44.01 per short ton in the Illinois Basin and from $42.68 to $66.27 per short ton in the Appalachian Basin, which are the prices used by RESPEC to estimate the amount of coal mineral reserves.  All reserves are classified as underground mineable in the production stage.  

Coal sales prices vary based on coal quality, access to transportation, and other factors at each location.  In the Illinois Basin, we have coal reserves that do not have associated coal resources. In addition, we have coal resources that are not associated with coal reserves and have different factors affecting the coal sales price.  As a result, the Illinois Basin reserves and the Illinois Basin resources have different price ranges.

Description

The potential underground mine(s) would utilize room-and-pillar methods operating a heavy media, float/sink style preparation plant.  Exploration continues as needed to fulfill possible permitting and development requirements.  Multiple access points are available for development.  Access is available from the active River View mine, which began production in 2009.  All equipment, facilities, infrastructure, and underground development are in good working order and maintained to industry standards.  Access at the Hamilton and UC Coal, LLC sites are considered "brownfield" developments. Though some facilities and permitting are in place, significant upgrades to existing infrastructure and new construction would be needed to bring them into good working order that meets industry standards. The property associated with Henderson/Union has no book value as of December 31, 2021 but does have outstanding advanced royalties with WKY CoalPlay or its subsidiaries.  See "Item 8. Financial Statements and Supplementary DataNote 21 – Related Party Transactions" for more information about advanced royalties that Henderson/Union has with WKY CoalPlay.

Though there is geographic overlap between the Henderson-Union and River View properties, the resources and reserves of each are associated with different coal seams or, if in the same seam, are separated by existing mine works or geologic features into distinct areas.  There is no overlap in the resource / reserve estimation.  

History

The Henderson/Union property contains resources in four seams, the West Kentucky No. 11 (WKY11), the West Kentucky No. 9 (WKY9), the West Kentucky No. 7 (WKY7), and the West Kentucky No. 6 (WKY6). Island Creek Coal Company ("Island Creek") operated mines in the area and controlled a portion of the property.  Under a joint venture, Texas Gas Service also controlled a large interest in the mineral rights.  Lastly, Peabody Coal Corporation ("Peabody") and Patriot Coal Corporation ("Patriot") operated mines in the area and controlled a portion of the reserves.  We consolidated control of the property through multiple transactions from 2005 through 2015.  Island Creek operated the Ohio #11 and Uniontown #9 mines.  Island Creek also operated the Hamilton #1 and #2 mines in Kentucky.  Peabody and

Table of Contents

later Patriot operated the Camp complex and Highland mines to the southeast and east.  Both the WKY9 and WKY11 seams were mined at these locations.  No mining has occurred on the property in the WKY7 or WKY6 seams.

Approximately 1,050 exploration holes have been drilled within and adjacent to the Henderson/Union area to assess thickness and mineability of the WKY11, WKY9, WKY7, and WKY6 seams. From these holes, over 410 samples were collected and analyzed to determine coal quality characteristics. Also, over 150 oil/gas well geophysical logs drilled by various companies have been interpreted to supplement the exploration drilling.  In general, all drilling has shown highly consistent coal seams of mineable thickness and quality for the high sulfur, thermal utility market.

Estimates of reserves as of December 31, 2021 were prepared using product prices equal to the unweighted arithmetic average of the first-day-of-the-month market price for each month in the period from January through December 2021.  The average realized product prices weighted by production over the remaining lives of the properties are $63.57/Bbl for oil, $2.98/Mcf of natural gas and $21.13 per barrel of NGL.  These prices are adjusted for energy content, associated average differential and transportation deducts by producing area to arrive at the net realized prices by product.  For 2021, NGL prices averaged approximately 37% of the posted oil prices during the course of the year with an additional $3.49/Bbl deducted for transportation costs.

The following table summarizes our changes in proved undeveloped reserves (in MBOE):

As a mineral interest owner we have no transparency into or control over our operators' investments and operational progress to convert PUDs to proved developed producing reserves. We do not incur any capital expenditures or lease operating expenses in connection with the development of our PUDs, which costs are borne entirely by our operators. As a result, during the year ended December 31, 2021, we did not have any expenditures to convert PUDs to proved developed producing reserves.  PUDs that have not been developed within two years of permitting are reviewed and removed from proved reserves as necessary.  As of December 31, 2021 approximately 16.48% of our total proved reserves were classified as PUDs.

Evaluation and Review of Reserves

Numerous uncertainties are inherent in estimating reserve volumes and values, and the estimates are subject to change as additional information becomes available. The reserves actually recovered and the timing of production of the reserves may vary significantly from the original estimates.

Table of Contents

Under SEC rules, proved reserves are those quantities of oil & gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible–from a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulations–prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. If deterministic methods are used, the SEC has defined reasonable certainty for proved reserves as a "high degree of confidence that the quantities will be recovered." All of our proved reserves as of December 31, 2021 were estimated using a deterministic method. The estimation of reserves involves two distinct determinations. The first determination results in the estimation of the quantities of recoverable oil & gas and the second determination results in the estimation of the uncertainty associated with those estimated quantities in accordance with the definitions established under SEC rules. The process of estimating the quantities of recoverable oil & gas reserves relies on the use of certain generally accepted analytical procedures. These analytical procedures fall into three broad categories or methods:

(1)performance-based methods,
(2)volumetric-based methods and
(3)analogy.

These methods may be used singularly or in combination by the reserve evaluator in the process of estimating the quantities of reserves. The proved reserves for our properties were estimated by performance methods, analogy or a combination of both methods. Performance methods include, but may not be limited to, decline curve analysis, which utilized extrapolations of available historical production data. The analogy method was used where there were inadequate historical performance data to establish a definitive trend and where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate.

To estimate economically recoverable proved reserves and related future net cash flows, our engineering team considered many factors and assumptions, including the use of reservoir parameters derived from geological, geophysical and engineering data which cannot be measured directly, economic criteria based on current costs and the SEC pricing requirements and forecasts of future production rates. To establish reasonable certainty with respect to our estimated proved reserves, the technologies and economic data used in the estimation of our proved reserves included production and well test data, downhole completion information, geologic data, electrical logs, and radioactivity logs.                        

Our 2021 year-end proved reserves were prepared by our internal engineering team.  Our engineering team works to ensure the integrity, accuracy, and timeliness of the data used to calculate our estimated proved reserves. Approximately 95% of our total 2021 year end proved reserve estimates were audited by NSAI. Our engineering team met with NSAI periodically during the period covered by the above referenced reserve report to discuss the assumptions and methods used in the reserve estimation process. Our engineering team provided historical information to NSAI for our properties, such as oil & gas production, well test data, and realized commodity prices. Our engineering team also provided ownership interest information with respect to our properties. Our internal petroleum engineer, primarily responsible for overseeing the petroleum reserves preparation, has over 20 years of engineering and operations experience in the oil & gas sector and a Bachelor of Science in Petroleum Engineering.

The preparation of our proved reserve estimates are completed in accordance with our internal control procedures. These procedures, which are intended to ensure reliability of reserve estimations, include the following:

review and verification of historical data, which is based on actual production as reported by our operators;
verification of property ownership by our land department;
review of all our reported proved reserves semi-annually including the review of all significant reserve changes and proved undeveloped reserves additions by our internal petroleum engineer;
internally prepared reserve estimates compared to reserves audit by NSAI;
review of changes in reserves semi-annually by our internal petroleum engineer and by senior management; and
no employee's compensation is tied to the amount of reserves booked.

NSAI, an independent third-party petroleum engineering firm, does not own an interest in any of our properties and is not employed on a contingent basis. When compared on a well-by-well basis, some of our estimates are greater and some are less than the NSAI estimates. NSAI is satisfied with our methods and procedures used to prepare the December 31, 2021 reserve estimates and future revenue, and noted nothing of an unusual nature that would cause NSAI to take

exception with the estimates, in the aggregate, prepared by us. NSAI's audit report with the respect to our proved reserve estimates as of December 31, 2021 is included as an exhibit to this Annual Report on Form 10-K.

NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-2699. Within NSAI, the technical persons primarily responsible for auditing the estimates meet or exceed the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; both are proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines.

Acreage Concentration

Our mineral interests, which include both proved reserves discussed above and unproved reserves, are primarily located in three basins, which are also our areas of focus for future operator development.  These include the Permian (Delaware and Midland), Anadarko (SCOOP/STACK) and Williston (Bakken) Basins.  Below is a chart reflecting our gross, net mineral and net royalty acreage associated with our mineral interests in each of our primary basins as of December 31, 2021.

Productive Wells

As of December 31, 2021, 6,572 gross productive horizontal wells and 4,167 gross productive vertical wells were located on the acreage in which we have a mineral interest.  Of our productive horizontal wells, 965 are considered natural gas wells, while the remaining 5,607 primarily produce oil.  Productive wells consist of producing wells and wells capable of production, including natural gas wells awaiting pipeline connections to commence deliveries and oil wells awaiting connection to production facilities.  We do not own any material working interests in any wells. Accordingly, we do not own any net wells.
