Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 7 1 Executive Summary 1.1 Property Description Alpha Metallurgical Resources, Inc. (Alpha) authorized Marshall Miller & Associates, Inc. (MM&A) to prepare this Technical Report Summary (TRS) of its controlled coal reserves located at the Aracoma Complex (Aracoma) in Logan County and Mingo counties, West Virginia. Active surface facilities for the operations are located along Rum Creek, a tributary of the Guyandotte River adjacent to a CSX rail line. The property which is located about 7 miles south of the town of Logan, West Virginia, the county seat of Logan County, and approximately 70 miles west southwest of Beckley (see Figure 1-1) is composed of approximately 114,300 total acres of mineral control, of which nearly all are contained within 30 separate leases. The mentioned leases are all subject to Alpha renewing the rights to extend the term of all leases which have various expiration dates, some of which expire in the next several years but are anticipated to be renewed by Alpha. Additionally, it is industry practice for major leases to have automatic renewal provisions in favor of the lessee. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 8 Figure 1-1: Alpha’s Aracoma Property Location Map 1.2 Ownership The Aracoma property involves a complex combination of previous ownership. Predecessors of Alpha, namely Alpha Natural Resources (Alpha) and Massey Energy (Massey) previously held mining rights on the majority of the property. 1.3 Geology Operations at the Aracoma Mine Complex currently extract coal from the Upper Chilton, Upper Cedar Grove, and No. 2 Gas seams by underground continuous mining method. These seams are all historically utilized as coking coal. Strata on the property reside in the Pennsylvanian-aged (approximately 290 to 330 million years ago) Kanawha Formation. Due to the high value of these coking coals, all the seams have been extensively mined in the past. The rock formations between the coal

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 9 seams are characterized by large proportions of sandstone interspersed with shale units. The coal seams reach the highest structural elevations along the southeastern margin of the property, generally dipping toward the northwest. 1.4 Exploration Status The Property has been extensively explored, largely by drilling using continuous coring and rotary drilling methods but also by obtaining coal measurements at mine exposures, and by downhole geophysical methods. A significant amount of historical data was acquired or generated by previous owners of the Property. These sources comprise the primary data used in the evaluation of the coal resources and coal reserves on the Property. MM&A examined the data available for the evaluation and incorporated all pertinent information into this TRS. Where data appeared to be anomalous or not representative, that data was excluded from the digital databases and subsequent processing by MM&A. Ongoing exploration has been carried out by Alpha since acquiring the Aracoma Complex. The Alpha acquired exploration data has been consistent with past drilling activities. 1.5 Operations and Development As of December 31, 2021, underground mine operations were active at the Davy Branch Deep Mine in the Upper Chilton seam, the Cedar Grove No. 2 Deep Mine in the Upper Cedar Grove seam, and the Lynn Branch Deep Mine in the No. 2 Gas coal seam. The Rum Creek mine and the Cedar Grove No. 3 mine are currently in the conceptual stage and are planned to operate in the No. 2 Gas coal seam and the Cedar Grove seam, respectively. These mines produce a High Vol-B metallurgical coal blend. Based on the mine plans developed as part of this TRS, annual deep mine production peaks at 2.1 million tons in 2040. Underground reserves will be depleted in 2047. In addition to the mines, the Aracoma Complex also includes the Bandmill Preparation Plant, which is also referred to as the Rum Creek Prep Plant. Last rebuilt in 2010, the plant site includes raw coal storage, clean coal storage, a centrifugal dryer, a railroad loadout as well as a refuse disposal area. Low density cyclones are used for intermediated separation and froth flotation & spirals are utilized for fine coal separation. The plant has a feed rate capacity of 1200 raw tons per hour and produces 7.31% ash at less than 1.1% sulfur. For year end 2021 the average utilization rate of the Bandmill Preparation Plant was 60.4% 1.6 Mineral Resource A coal resource estimate, summarized in Table 1-1 was prepared as of December 31, 2021, for property controlled by Alpha.

Note (2): Coal resources are reported on a dry basis. Surface moisture and inherent moisture are excluded. Note (3): The Property contains 140.66 Mt of dry, in-place measured and indicated coal resources exclusive of reserves as of December 31, 2021. Totals may not add due to rounding. See Appendix A for more detailed breakdown. 1.7 Mineral Reserve The Resource estimate outlined in Table 1-1 inclusive of reserves has been used as the basis for this Reserve calculation, which utilizes a reasonable Preliminary Feasibility Study, a Life-of Mine (LOM) Mine Plan and practical recovery factors. Production modeling was completed with an effective start date of January 1, 2022. Factors that would typically preclude conversion of a coal resource to coal reserve, include the following: inferred resource classification; absence of coal quality; poor mine recovery; lack of access; geological encumbrances associated with overlying and underlying strata; seam thinning; structural complication; and insufficient exploration have all been considered. Reserve consideration excludes those portions of the resource area, which exhibit the aforementioned geological and operational encumbrances. Proven and probable coal reserves were derived from the defined in-situ coal resource considering relevant processing, economic (including technical estimates of capital, revenue and cost), marketing, legal, environmental, socioeconomic, and regulatory factors. The proven and probable coal reserves on the Property are summarized below in Table 1-2.

Coal quality is based on a weighted average of laboratory data from core holes The combination of surface and inherent moisture is modeled at 6.0-percent. Actual product moisture is dependent upon multiple geological factors, operational factors, and product contract specifications and can exceed 8-percent. As such, the modeled moisture values provide a level of conservatism for reserve reporting. *Volatile Matter analysis is not available for all reserve areas. All Aracoma reserves are priced as a High-Vol. B product. Totals may not add due to rounding. See Appendix A for more detailed breakdown. In summary, as of December 31, 2021, Alpha controls a total of 44.18 Mt (moist basis) of marketable coal reserves at Aracoma. Of that total, 59 percent are proven, and 41 percent are probable. Approximately 5.25 Mt are owned, and the remaining 38.93 Mt are leased coal reserves. The maps included in Appendix C reflect mining depletion at the time of the resource/reserve calculation taken from Alpha mine maps at various points during calendar year 2021. Mine depletion tonnages were supplied by Alpha through the end of 2021, and MM&A deducted this historical production from the mapped reserves in order to estimate reserves as of December 31, 2021. 1.8 Capital Summary Alpha provided MM&A with information related to the number of currently operating production units at Aracoma. MM&A’s capital schedules assume that major equipment rebuilds occur over the course of each machine’s remaining assumed operating life. Replacement equipment was scheduled based on MM&A’s experience and knowledge of mining equipment and industry standards with respect to the useful life of such equipment. As one mine is depleted, the equipment is moved to its replacement. The capital expenditures tables detail costs for major equipment and infrastructure such as conveyor belt terminal groups. “Other” costs include expenditures for mine access and construction, mine extension capital and miscellaneous costs. A summary of the estimated capital for the consolidated Aracoma operations is provided in Figure 1-2 below. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 12 Figure 1-2: Projected Capital Expenditures – Consolidated Aracoma Operations 1.9 Operating Costs Alpha provided historical costs and budgeted projections of operating costs for its active mines; Davy Branch Deep Mine, Cedar Grove No. 2 ,Lynn Branch No. 2 Mine, and the recently closed Aracoma Alma Mine for MM&A’s review. MM&A used the historical and/or budget cost information as a reference and developed a personnel schedule for each mine. Hourly labor rates and salaries were based upon information contained in Alpha’s financial summaries. Fringe benefit costs were developed for vacation and holidays, federal and state unemployment insurance, retirement, workers’ compensation and pneumoconiosis, casualty and life insurance, healthcare and bonuses. A cost factor for mine supplies was developed that relates expenditures to mine advance rates for roof control costs and other mine supply costs based on the historical cost data provided by Alpha. Other factors were developed for maintenance and repair costs, rentals, mine power, outside services, coal preparation plant processing, refuse handling, coal loading, property taxes, and insurance and bonding and other direct mining costs. Appropriate royalty rates were assigned for production from leased coal lands and sales taxes were calculated for state severance taxes, the federal black lung excise tax, and federal and state reclamation fees. Company-wide pricing data as provided by Alpha is described in Table 16-2. Note that not all products reflected in Table 16-2 will apply to every business unit. The pricing data assumes a flat-line long term

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 13 realization of $117 per short ton port pricing, with an average $87.72 per ton netback pricing reflective of the high-volatile product currently sold at Aracoma. These estimates are based on long term pricing published by third party sources and adjusted for quality and transportation. The netback pricing represents adjustments made to published benchmark pricing based on quality and transportation. A large majority of the coal sold by Alpha and their Aracoma business group is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. These netback adjustments reflect these additional costs carried after the products leave the Aracoma business unit. A summary of the projected operating costs for the consolidated Aracoma operations is provided in Figure 1-3. Figure 1-3: Aracoma Operating Costs 1.10 Economic Evaluation The pre-feasibility financial model prepared for this TRS was developed to test the economic viability of each coal resource area. The results of this financial model are not intended to represent a bankable feasibility study, required for financing of any current or future mining operations contemplated for the Alpha properties, but are intended to establish the economic viability of the estimated coal reserves. Cash flows are simulated on an annual basis based on projected production from the coal reserves. The discounted cash flow analysis presented herein is based on an effective date of January 1, 2022. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 14 On an un-levered basis, the NPV of the project cash flow after taxes represents the Enterprise Value of the project. The project cash flow, excluding debt service, is calculated by subtracting direct and indirect operating expenses and capital expenditures from revenue. Direct costs include labor, operating supplies, maintenance and repairs, facilities costs for materials handling, coal preparation, refuse disposal, coal loading, reclamation, and general and administrative costs. Indirect costs include statutory and legally agreed upon fees related to direct extraction of the mineral. The indirect costs are the Federal black lung tax, Federal and State reclamation taxes, property taxes, coal production royalties, and income taxes. The Alpha mines’ historical costs provided a useful reference for MM&A’s cost estimates. Table 1-3 shows LOM tonnage, P&L, and EBITDA for each Alpha mine at Aracoma.

LOM tonnage evaluated in the financial model includes 4th quarter 2021 production (500,817 clean tons) which was subtracted from coal reserves in order to make the effective date of the reserves December 31, 2021. As shown in Table 1-3, all of the mines analyzed show positive EBITDA over the LOM. Overall, the Alpha consolidated Aracoma operations show positive LOM P&L and EBITDA of $591.2 million and $934.5 million, respectively. Alpha’s consolidated Aracoma cash flow summary in constant dollars, excluding debt service, is shown in Table 1-4 below.

LOM tonnage evaluated in the financial model includes 4th quarter 2021 production (500,817 clean tons) which was subtracted from coal reserves in order to make the effective date of the reserves December 31, 2021. Consolidated cash flows are driven by annual sales tonnage, which peaks at 2.2 million tons in 2022. Between years 2023 and 2043, sales ranges from 1.5 million to 2.1 million tons and between years 2044-2047, sales range from 0.3 million tons to 1.1 million tons. Projected consolidated revenue peaks at $194.6 million in 2022 and totals $3.9 billion for the project’s life. Consolidated cash flow from operations is positive throughout the projected operating period, with the exception of post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $52.1 million in 2023 and totals $827.0 million over the project life. Capital expenditures total $57.0 million during the first five years and $230.5 million over the project’s life. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 16 1.10.1 Discounted Cash Flow Analysis Cash flow after tax, but before debt service, generated over the life of the project was discounted to NPV at a 14.67% discount rate, which represents MM&A’s estimate of the constant dollar, risk adjusted WACC for likely market participants if the subject reserves were offered for sale. On an un-levered basis, the NPV of the project cash flows represents the Enterprise Value of the project and amounts to $221.8 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the Aracoma reserves. The pre-feasibility financial model prepared for the TRS was developed to test the economic viability of each coal resource area. The NPV estimate was made for purposes of confirming the economics for classification of coal reserves and not for purposes of valuing Alpha or its Aracoma assets. Mine plans were not optimized, and actual results of the operations may be different, but in all cases, the mine production plan assumes the properties are under competent management. 1.10.2 Sensitivity Analysis Sensitivity of the NPV results to changes in the key drivers is presented in the chart below. The sensitivity study shows the NPV at the 14.67% discount rate when Base Case sales prices, operating costs, capital costs, and discount rate are increased and decreased in increments of 5% within a +/- 15% range. Figure 1-4: Sensitivity of NPV

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 17 As shown, NPV is quite sensitive to change in sales price, operating cost estimates and the discount rate, and slightly sensitive to changes in capital cost estimates. 1.11 Permitting Alpha has obtained all mining and discharge permits to operate its active mines and processing, loadout or related support facilities. MM&A is unaware of any obvious or current Alpha permitting issues that are expected to prevent the issuance of future permits. Alpha, along with all coal producers, is subject to a level of uncertainty regarding future clean water permits due to United States Environmental Protection Agency (EPA) involvement with state programs. 1.12 Conclusion and Recommendations Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the Aracoma Property and reviewed in the study. The data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS. The geological data and preliminary feasibility study, which consider mining plans, revenue, and operating and capital cost estimates are sufficient to support the classification of coal reserves provided herein. This geologic evaluation conducted in conjunction with the preliminary feasibility study concludes that the 44.18 Mt of marketable underground coal reserves identified on the Property are economically mineable under reasonable expectations of market prices for metallurgical coal products, estimated operation costs, and capital expenditures. 2 Introduction 2.1 Registrant and Terms of Reference This report was prepared for the sole use of Alpha Metallurgical Resources, Inc. (Alpha) and its affiliated and subsidiary companies and advisors. The report provides a statement of coal reserves for Alpha. Exploration results and Resource calculations were used as the basis for the mine planning and the preliminary feasibility study completed to determine the extent and viability of the reserve. Coal resources and coal reserves are herein reported in imperial units of measurement and are rounded to millions of short tons (Mt). Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 18 2.2 Information Sources The technical report is based on information provided by Alpha and reviewed by MM&A’s professionals, including geologists, mining engineers, civil engineers, and environmental scientists. MM&A’s professionals hold professional registrations and memberships which qualify them as Qualified Persons in accordance with SEC guidelines. Alpha engaged MM&A to conduct a coal reserve evaluation of the Alpha coal properties as of December 31, 2021. For the evaluation, the following tasks were to be completed: > Conduct site visits of the mines and mine infrastructure facilities; > Process the information supporting the estimation of coal resources and reserves into geological models; > Develop life-of-reserve mine (LOM) plans and financial models; > Hold discussions with Alpha company management; and > Prepare and issue a Technical Report Summary providing a statement of coal reserves which would include: - A description of the mines and facilities. - A description of the evaluation process. - An estimation of coal reserves with compliance elements as stated under the new SEC Guidelines which will become effective for the first fiscal year commencing on or after January 1, 2022. 2.3 Personal Inspections MM&A is very familiar with Aracoma, having provided a variety of services in recent years and QP’s involved in this TRS have conducted multiple site visits. 3 Property Description 3.1 Location The Aracoma Mine Complex is located in the Central Appalachian Basin in southern West Virginia (see Figure 1-1) approximately 7 miles south of the town of Logan, West Virginia, the county seat of Logan County and 70 miles west of Beckley, which is the county seat of Raleigh County. Surface facilities for the operation are located in the Guyandotte River drainage basin, central to the active Mines as well as those currently in development. Numerous small communities are present throughout the property such as the previously mentioned Logan, as well as Stollings, Omar and Barnabus.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 19 The nearest major population centers are Charleston, West Virginia (65 miles north), Bristol, Virginia (140 miles south), Roanoke, Virginia (190 miles east), and Morgantown, West Virginia (220 miles north), and Lexington, Kentucky (190 miles west). The property is located on the following United States Geological Survey (USGS) Quadrangles: Holden, Barnabus, Man, Mallory, Amherstdale, Lorado, Wharton, Clothier, and Logan. The coordinate system and datum used for the model of the Aracoma Mine complex and the subsequent maps were produced in the West Virginia State Plane South system, NAD 27. 3.2 Titles, Claims or Leases The property is composed of over 114,000 total acres of mineral control, nearly all of which is leased. Alpha’s control is comprised of over 30 separate leases with varying expiration dates. Some leases expire over the next several years, but Alpha does not anticipate any challenges related to lease renewal. MM&A has not carried out a separate title verification for the coal properties and has not verified leases, deeds, surveys, or other property control instruments pertinent to the subject resources. Alpha has represented to MM&A that it controls the mining rights to the reserves as shown on its property maps, and MM&A has accepted these as being a true and accurate depiction of the mineral rights controlled by Alpha. The TRS assumes the property is developed under responsible and experienced management. 3.3 Mineral Rights Alpha supplied property control maps to MM&A related to properties for which mineral and/or surface property are controlled by Alpha. While MM&A accepted these representations as being true and accurate, through past knowledge of the Property MM&A has no knowledge of past property boundary disputes or other concerns, that could impact future mining operations or development potential. Property control in Appalachia can be intricate. Coal mining properties are typically composed of numerous property tracts which are owned and/or leased from both land holding companies and private individuals or companies. It is common to encounter severed ownership, with different entities or individuals controlling the surface and mineral rights. Mineral control in the region is typically characterized by leases or ownership of larger tracts of land, with surface control generally comprised of smaller tracts, particularly in developed areas. Control of the surface property is necessary to conduct surface mining but is not necessary to conduct underground mining aside from relatively limited areas required for seam access or ventilation infrastructure. Alpha’s executive management team has a history of mining in Central Appalachia and has conveyed to MM&A that it has been successful in acquiring surface rights where needed for past operations.

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 20 3.4 Encumbrances No Title Encumbrances are known. By assignment, MM&A did not complete a query related to Title Encumbrances. 3.5 Other Risks There is always risk involved in property control. As is common practice, Alpha, and its predecessors, have had their land teams examine the deeds and title control to minimize this risk. Historically, property control has not posed any significant challenges related to Aracoma’s operations. 4 Accessibility, Climate, Local Resources, Infrastructure and Physiography 4.1 Topography, elevation and Vegetation Topography of the area surrounding the Aracoma mine complex is typical of the Central Appalachian Plateau’s physiographic province, being rugged and deeply dissected by V-shaped river valleys and flanked by steep-sided upland regions. Slopes in the area are mostly steep to very steep with some gently sloping with relatively narrow ridges. Surface elevations near the mine complex range from approximately 1,200 feet above sea level at streams to approximately 2,200 feet at ridge tops. The area is heavily vegetated and has a significant amount of hardwood forests. The property is not situated near any major urban centers. 4.2 Access and Transport There is general access to the Aracoma property via a well-developed network of primary, secondary, and unimproved roads. Interstates 64 and 77 converge at Beckley, WV, and are the primary roads in the area connecting to Beckley, Charleston, and Huntington, West Virginia, to the West and Lexington, Virginia, to the East. Numerous secondary and unimproved roads provide direct access to the mine property, some being federal-, state-, and town-maintained. These include State Route 119 running east-west from Danville to Logan and State Route 10 running north-south from Logan to Man. These roads typically stay open throughout the year. Within the property, unimproved roads are utilized to access gas drainage wells and surface based deep mine infrastructure. An Alpha-owned preparation plant and rail loadout are located approximately 12 miles southeast of the town of Logan along the CSX railroad system and serve as the primary transport means of processed coal. 4.3 Proximity to Population Centers The Aracoma Mine Complex is located near the town of Logan and is primarily in Logan and Boone Counties, West Virginia, with small portions falling in Mingo County. There are no large population centers in proximity. The nearest major population centers are Charleston, West Virginia (65 miles

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 21 north), Bristol, Virginia (140 miles south), Roanoke, Virginia (190 miles east), and Morgantown, West Virginia (220 miles north), and Lexington, Kentucky (190 miles west). As of the 2010 census, Logan County had just over 36,700 residents. 4.4 Climate and Length of Operating Season The climate of the region is classified as humid continental with four distinct seasons: warm summers, cold winters, and moderate fall and spring seasons. Precipitation in the region is consistent throughout the year, approximately 3 to 5 inches per month, with the most rain falling in spring and the early months of summer. Average yearly precipitation is 47 inches. Summer months typically begin in late May and end in early September and range in average temperature from 50 to 83 degrees Fahrenheit. Winters typically begin in mid to late November and run until mid to late March with average temperatures ranging from 23 to 54 degrees Fahrenheit. Precipitation in the winter typically comes in the form of snowfall or as a wintery mix (sleet and snow) with severe snowfall events occurring occasionally. Seasonal variations in climate typically do not affect underground mining in West Virginia. However, weather events could potentially negatively impact efficiency of surface and preparation plant operations on a very limited basis and lasting less than a few days. 4.5 Infrastructure The Aracoma Mine Complex has sources of water, power, personnel, and supplies readily available for use. Personnel have historically been sourced from the surrounding communities in Logan, Mingo, Wyoming, and Boone Counties and have proven to be adequate in numbers to conduct mining operations. As mining is common in the surrounding areas, the workforce is generally familiar with mining practices, and many are experienced miners. Water is sourced locally from public water sources or rivers, and electricity is sourced from Appalachian Power, a subsidiary of American Electric Power (AEP). The service industry in the areas surrounding the mine complex has historically provided supplies, equipment repairs and fabrication, etc. Alpha’s Bandmill preparation plant services consumers in with washed coal, which is transported via the adjacent CSX rail line at the Aracoma loadout. Haul roads, primary roads, and conveyor belt systems account for transport from the various mine sites to the preparation plant. 5 History 5.1 Previous Operation The Aracoma property involves a complex combination of previous ownership. Coal mining in the area occurred for nearly a century. Predecessors of Alpha, namely Alpha Natural Resources (Alpha) and Massey Energy (Massey) previously held mining rights on much of the property. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 22 5.2 Previous Exploration Extensive exploration in the form of subsurface drill efforts has been carried out on the property by numerous entities, most of which efforts were completed prior to the inception of Alpha. Diamond core and rotary drilling are the primary types of exploration on the property. Data for correlation and mining conditions are derived from core descriptions and geophysical logging (e-logging). Coal-quality analyses were also employed during the core-exploration process. Development of this report included an assessment of over 5,375 coal measurements, largely comprised of exploration drill holes. Drill records indicate that independent contract drilling operators have typically been engaged to carry out drilling on the Property. Geophysical logging was typically performed by outside logging firms. MM&A, via its Geophysical Logging Systems subsidiary, has logged a significant number of the past exploration holes, and currently logs most of the recently drilled holes. 6 Geological Setting, Mineralization and Deposit 6.1 Regional, Local and Property Geology The property lies in the Central Appalachian Coal basin in the Appalachian Plateau physiographic province. The coal deposits in the eastern US are the oldest and most extensively developed coal deposits in the country. The coal deposits on the Property are Carboniferous in age, being of the Pennsylvanian system. Overall, these Carboniferous coals contain two-fifths of the US’s bituminous coal deposits and extend over 900 miles from northern Alabama to Pennsylvania and are part of what is known as the Appalachian Basin. The Appalachian Basin is more than 250 miles wide and, in some portions, contains over 60 coal seams of varying economic significance. Seams and zones of economic significance typically range between 24 and 48 inches in thickness, with relatively little structural deformation. Regional structure is typically characterized by gently dipping strata to the northwest at one to four percent, averaging three percent. Strata on the property are of the Pennsylvanian-age Kanawha Formation of the Pottsville Series. The rock formations between the coal seams are characterized by large proportions of sandstone interspersed with shale units. Seams with remaining reserve or resource potential include, in stratigraphically ascending order the: No. 2 Gas, Alma, Lower Cedar Grove, Upper Cedar Grove Chilton and Upper Chilton.

Figure 6-1: Aracoma Stratigraphic Column (not to scale) 6.3 Deposits The coal produced at the Aracoma complex is a High-Volatile-B bituminous coal. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 24 Due to the high value of these High volatile coking coals, all the seams have been extensively mined in the past. The coal seams reach the highest structural elevations along the southeastern margin of the property, generally dipping toward the northwest. The upper seams of interest are situated above drainage and are accessible via outcrop, the deeper No. 2 Gas seam is below drainage where slope and shaft access are required. The rock formations between the coal seams are characterized by large portions of sandstone with shale units interspersed throughout. 7 Exploration 7.1 Nature and Extent of Exploration The Property has been extensively explored by subsurface drilling efforts carried out by numerous entities, most of which were completed prior to ownership by Alpha. Diamond core and rotary drilling are the primary types of exploration on the property. Data for correlation and mining conditions are derived from core descriptions and geophysical logging (e- logging). Coal-quality analyses were also employed during the core-exploration process. Drill records indicate that independent contract drilling operators have typically been engaged to carry out drilling on the Property. Geophysical logging was typically performed by outside logging firms. MM&A, via its Geophysical Logging Systems subsidiary, has logged a significant number of the past exploration holes, and currently logs most of the recently drilled holes. The location of the drilling is shown on the maps included in Appendix C. The concentration of exploration varies slightly across the property. Drilling on the property is typically sufficient for delineation of potential surface, highwall miner, and deep mineable coal horizons. Core logging is carried out by geologists in cases where roof and floor strata are of particular interest and in cases where greater resolution and geologic detail are needed. In many cases the drill hole data comes from simplified driller’s logs, which may lack specific details regarding geotechnical conditions and specific geology, making correlations and floor and roof conditions difficult to determine. Geophysical logging (e-logging) techniques, by contrast, document specific details useful for geologic interpretation and mining conditions. Given the variability of data-gathering methods, definitive mapping of future mining conditions may not be possible, but projections and assumptions can be made within a reasonable degree of certainty. A significant effort was put into verifying the integrity of the database. Once this was established, stratigraphic columnar sections were generated using cross-sectional analysis to establish or confirm coal seam correlations. A typical cross-section is shown in Figure 7-1.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 25 Figure 7-1: Aracoma Cross-Section Due to the long history of exploration by various parties on the Property, a wide variety of survey techniques exist for documentation of data point locations. Many of the older exploration drill holes appear to have been located by survey and more recently completed drill holes are often located by high-resolution Global Positioning System (GPS) units. However, some holes appear to have been approximately located using USGS topography maps or other methods which are less accurate. Therefore, discretion had to be used regarding the accuracy for the location and ground surface elevation of some of these older drill holes. In instances where a drill hole location (or associated coal seam elevations) appeared to be inconsistent with the overall structural trend (or surface topography for surface-mineable areas), the data point was not honored for geological modeling. Others with apparently minor variances were adjusted and then used by MM&A. Surveying of the underground and surface mined areas has been performed by the mine operators and/or their consulting surveyors. By assignment, MM&A did not verify the accuracy or completeness of supplied mine maps but accepted this information as being the work of responsible engineers and surveyors, as required by both State and Federal Law. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 26 MM&A compiled comprehensive topographic map files by selecting the best available aerial mapping for each area and filling any gaps with digital USGS topographic mapping. 7.2 Drilling Procedures Core drilling methods utilize NX-size (21/8 inch) or similar-sized core cylinders to recover core samples, which can be used to delineate geologic characteristics, and for coal quality testing and geotechnical logging. For the core holes, the geophysical logs are especially useful in verifying the core recovery of both the coal samples (for assurance that sample is representative of the full seam) and of the roof and floor rock samples (for evaluating ground control characteristics of deep mineable coal seams). In addition to the core holes, rotary drilled holes also exist on most of the Property. Data for the rotary drilled holes is mainly derived from downhole geophysical logs, which are used to interpret coal and rock thickness and depth since logging of the drill cuttings is not reliable. A wide variety of core-logging techniques exist for the Property. For many of the core holes, the primary data source is a generalized lithology description by the driller, typically supplemented by a more detailed core log completed by a geologist. These drilling logs were provided to MM&A as a geological database. MM&A geologists were not involved in the production of original core logs but did perform a basic check of information within the provided database. Where geophysical logs for such holes are available, they were used by MM&A geologists to verify the coal thickness and core recovery of seams. 7.3 Hydrology Hydrologic testing and forecasting are necessary parts of the permitting process and as such are routinely considered in the mine planning process. Aracoma has a lengthy history of operation and three currently active mines with no significant hydrologic concerns or material issues experienced in its history. Future mining is projected to occur in areas exhibiting similar hydrogeological conditions as past mining. Based upon the successful history of the operation with regards to hydrogeological features, MM&A assumes that the operation will not be hindered by such issues in the future. 7.4 Geotechnical Data Life-of-Mine (LOM) Mining plans for potential underground mines were developed by MM&A through incorporation of budget maps from Alpha. Pillar stability was tested by MM&A using the Analysis of Coal Pillar Stability (ACPS) program that was developed by the National Institute for Occupational Safety and Health (NIOSH). MM&A reviewed the results from the ACPS analysis and considered it in the development of the LOM plan. Coal and rock strengths from core testing are used to verify the empirical assumptions integral to ACPS.

The protocol for preparing and testing the samples has varied over time and is not well documented for the older holes drilled on the Property. Typical US core drilling sampling technique is for the coal core sample, once recovered from the core barrel, to be described then wrapped in a sealed plastic sleeve and placed into a covered core box, which is the length of the sample so that the core can be delivered to a laboratory in relatively intact condition and with original moisture content. The core identification number and the depth are scribed on the sample box lid to identify the sample. This process has been the norm for both historical and ongoing exploration activities at Aracoma. This work is typically performed by the supervising driller, geologist or company personnel. Samples are most often delivered to the company by the driller after each shift or acquired by company personnel or representatives. Most of the coal core samples were obtained by previous operators on the Property. MM&A did not participate in the collection, sampling, and analysis of the majority of core samples within the exploration database. However, it is reasonable to assume, given the sophistication level of the previous operators, that these samples were generally collected and processed under industry best-practices. This assumption is based on MM&A’s familiarity with the operating companies and the companies used to perform the analysis. 8.2 Lab Procedures Coal quality testing has been performed over a large number of years by operating companies using different laboratories and testing regimens. Some of the samples have raw analyses and washabilities on the full seam (with coal and rock parting layers co-mingled) and are mainly useful for characterizing the coal quality for projected production from underground and highwall mining. Other samples have coal and rock analyzed separately, the results of which can be manipulated to forecast either surface or underground mining quality. Care has been taken to use only those analyses that are representative of the coal quality parameters for the appropriate mining type for each sample. Standard procedure upon receipt of core samples by the testing laboratory is to log the depth and thickness of the sample, then perform testing as specified by a representative of the operating company. Each sample is then analyzed in accordance with procedures defined under American Society for Testing and Materials (ASTM) standards including, but not limited to; washability (ASTM D4371); ash (ASTM D3174); sulfur (ASTM D4239); Btu/lb. (ASTM D5865); volatile matter (ASTM D3175); and Free Swell Index (FSI) (ASTM D720). Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 28 9 Data Verification 9.1 Procedures of Qualified Person MM&A reviewed the Alpha-supplied digital geologic database and supplemented the database with its own in-house records which have been maintained for both Alpha and previous operators of the property. The database consists of data records, which include drill hole information for holes that lie within and adjacent to the Property along with records for numerous supplemental coal seam thickness measurements. Once the initial integrity of the database was established, stratigraphic columnar sections were generated using in cross-sectional analysis to establish or confirm coal seam correlations. Geophysical logs were used wherever available to assist in confirming the seam correlation and to verify proper seam thickness measurements and recovery of coal samples. After establishing and/or verifying proper seam correlation, seam data control maps and geological cross-sections were generated and again used to verify seam correlations and data integrity. Once the database was fully vetted, seam thickness, base-of-seam elevation, roof and floor lithology, and overburden maps were independently generated for use in the mine planning process. Coal quality was analyzed and summarized by MM&A’s team of geologists and engineers. Quality was provided by Alpha in various database formats, laboratory data sheets, and also obtained directly from MM&A’s files. Care was taken to ensure that sampled data was representative of the mineable section. In instances where minimal representative data was noted, geological tonnages were estimated based upon applying assumed densities of coal and non-coal material to thicknesses expressed in geological database files. 9.2 Limitations As with any exploration program, localized anomalies, such as a thin coal area or poor mining conditions, cannot always be identified. The greater the density of the samples taken, the less the risk. Once an area is identified as being of interest for inclusion in the mine plan, additional samples are taken to help reduce the risk in those specific areas. In general, provision is made in the mine planning portion of the study to allow for localized anomalies that are typically classed more as a nuisance than a hinderance. 9.3 Opinion of Qualified Person Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the Aracoma Property. The data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS.

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 29 10 Mineral Processing and Metallurgical Testing 10.1 Testing Procedures Basic chemical analyses (both raw and washed quality), petrographic data, rheological data and ash, ultimate and sulfur analysis are available but not summarized for this filing. Available coal quality data sourced from MM&A’s vaults (associated with former projects for Alpha and its predecessors) was tabulated by resource area in a Microsoft® EXCEL workbook. Such data contained laboratory sheets which MM&A utilized to confirm that sampled intervals were representative of geological models and confirm that appropriate laboratory procedures were utilized to derive raw and clean coal parameters. Additionally, Alpha provided MM&A with a database of its own in-house coal quality information which did not include backup laboratory information or sampled intervals. MM&A compared wash recovery values from Alpha’s dataset to proximal holes with wash recovery data in MM&A’s dataset and calculated estimates of wash recovery based upon the relative percentages of coal and rock from lithologic descriptions. In general, MM&A found that Alpha’s dataset was representative and appropriate for inclusion in coal quality summaries. Quality tables also provide basic statistical analyses of the coal quality datasets, including average value; maximum and minimum values; and the number of samples available to represent each quality parameter of the seam. Coal samples that were deemed by MM&A geologists to be unrepresentative were not used for statistical analysis of coal quality, as documented in the tabulations. Specific to the surface mine reserve areas, exploration quality was supplemented with historical pit sampling. Tabulations were completed based upon annual arithmetic averages on in-pit samples for washed quality. The general consistency in quality suggests confidence in the mines’ ability to continue to produce a comparable metallurgical product. The amount and areal extent of coal sampling for geological data is generally sufficient to represent the quality characteristics of the coal horizons and allow for proper market placement of the subject coal seams. For some of the coal deposits there are considerable laboratory data from core samples that are representative of the full extent of the resource area; and for others there are more limited data to represent the resource area. For example, in the active operations with considerable previous mining, there may be limited quality data within some of the remaining resource areas; however, in those cases the core sampling data can be supplemented with operational data from mining and shipped quality samples representative of the resource area. 10.2 Relationship of Tests to the Whole The extensive sampling and testing procedures typically followed in the Coal Industry result in an excellent correlation between samples and Marketable product. As shipped analyses of the coal from Aracoma were reviewed to verify that the coal quality and characteristics were as expected. The Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 30 Aracoma Property has a long history of saleable production, under various owners, in the High-volatile metallurgical and thermal markets, confirming exploration results. 10.3 Lab Information Each sample is analyzed at area Laboratories that operate in accordance with procedures defined under ASTM standards including, but not limited to; washability (ASTM D4371); ash (ASTM D3174); sulfur (ASTM D4239); Btu/lb. (ASTM D5865); volatile matter (ASTM D3175); Free Swell Index (FSI) (ASTM D720). 10.4 Relevant Results No critical factors have been found that would adversely affect the recovery of the Reserve. Any quality issues that occur, either localized or generally are accounted for in the Marketing Study done for this TRS. 11 Mineral Resource Estimates MM&A independently created a geologic model to define the coal resources at Aracoma. Coal resources were estimated as of December 31, 2021. 11.1 Assumptions, Parameters and Methodology Geological data was imported into Carlson Mining® (formerly SurvCADD®) geological modelling software in the form of Microsoft® Excel files incorporating drill hole collars, seam and thickness picks, bottom seam elevations and raw and washed coal quality. These data files were validated prior to importing into the software. Once imported, a geologic model was created, reviewed, and verified- with a key element being a gridded model of coal seam thickness. Resource tons were estimated by using the seam thickness grid based on each valid point of observation and by defining resource confidence arcs around the points of observation. Points of observation for Measured and Indicated confidence arcs were defined for all valid drill holes that intersected the seam using standards deemed acceptable by MM&A based on a detailed geologic evaluation and a statistical analysis of all drill holes within the projected reserve areas as described in Section 11.1.1. The geological evaluation incorporated an analysis of seam thickness related to depositional environments, adjacent roof and floor lithologies, and structural influences. After validating coal seam data and establishing correlations, the thickness and elevation for seams of economic interest were used to generate a geologic model. Due to the relative structural simplicity of the deposits and the reasonable continuity of the tabular coal beds, the principal geological interpretation necessary to define the geometry of the coal deposits is the proper modeling of their thickness and elevation. Both coal thickness and quality data are deemed by MM&A to be reasonably

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 31 sufficient within the resource areas. Therefore, there is a reasonable level of confidence in the geologic interpretations required for coal resource determination based on the available data and the techniques applied to the data. Table 11-1 below provides the geological mapping and coal tonnage estimation criteria used for the coal resource and reserve evaluation. These cut-off parameters have been developed by MM&A based on its experience with the Alpha Property and are typical of mining operations in the Central Appalachian coal basin. This experience includes technical and economic evaluations of numerous properties in the region for the purposes of determining the economic viability of the subject coal reserves.

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 32 11.1.1 Geostatistical Analysis MM&A completed a geostatistical analysis on drill holes within the reserve boundaries to determine the applicability of the common United States classification system for measured and indicated coal resources. Historically, the United States has assumed that coal within ¼-mile (1,320 feet) of a point of observation represents a measured resource whereas coal between ¼-mile (1,320 feet) and ¾-mile (3,960 feet) from a point of observation is classified as indicated. Inferred resources are commonly assumed to be located between ¾-mile (3,960 feet) and 3 miles (15,840 feet) from a point of observation. Per SEC regulations, only measured and indicated resources may be considered for reserve classification, respectively, as proven and probable reserves. MM&A performed a geostatistical analysis test of the Aracoma data set using the Drill Hole Spacing Analysis (DHSA) method. This method attempts to quantify the uncertainty of applying a measurement from a central location to increasingly larger square blocks and provides recommendations for determining the distances between drill holes for measured, indicated, and inferred resources. To perform DHSA the data set was processed to remove any erroneous data points, clustered data points, as well as directional trends. This was achieved through the use of histograms, as seen in Figure 11-1, color coded scatter plots showing the geospatial positioning of the borings, Figure 11-2, and trend analysis.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 33 Following the completion of data processing, a variogram of the data set was created, Figure 11-3. The variogram plots average square difference against the separation distance between the data pairs. The separation distance is broken up into separate bins defined by a uniform lag distance (e.g., for a lag distance of 500 feet the bins would be 0 – 500 feet, 501 – 1,000 feet, etc.). Each pair of data points that are less than one lag distance apart are reported in the first bin. If the data pair is further apart than one lag distance but less than two lag distances apart, then the variance is reported in the second bin. The numerical average for differences reported for each bin is then plotted on the variogram. Care was taken to define the lag distance in such a way as to not overestimate any nugget effect present in the data set. Lastly, modeled equations, often spherical, gaussian, or exponential, are applied to the variogram in order to represent the data set across a continuous spectrum. Figure 11-3: Variogram of the Total Seam Thickness for the No. 2 Gas Seam Present in the Aracoma Complex The estimation variance is then calculated using information from the modeled variogram as well as charts published by Journel and Huijbregts (1978). This value estimates the variance from applying a single central measurement to increasingly larger square blocks. Care was taken to ensure any nugget effect present was added back into the data. This process was repeated for each test block size. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 34 The final step of the process is to calculate the global estimation variance. In this step the number square blocks that would fit inside the selected study area is determined for each block size that was investigated in the previous step. The estimation variance is then divided by the number of blocks that would fit inside the study area for each test block size. Following this determination, the data is then transformed back to represent the relative error in the 95th-percentile range. Figure 11-4 shows the results of the DHSA performed on the No. 2 Gas seam data for the Aracoma Complex. DHSA provides hole to hole spacing values, these distances need to be converted to radius from a central point in order to compare to the historical standards. A summary of the radius data is shown in Table 11-2. DHSA prescribes measured, indicated, and inferred drill hole spacings be determined at the 10-percent, 20-percent, and 50-percent levels of relative error, respectively.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 35 measured resources. The Spherical model recommends using a radius of 0.45 miles for measured resources compared to the historical value of 0.25 miles. With respect to indicated resources the DHSA falls in line closely with the historical standards. The Spherical model recommends using a radius 0.85 miles, while the Gaussian and Exponential models recommend a radius of 0.88 miles. These values line up closely with the historical radius of 0.75 miles. These results have led the QP’s to report the data following the historical classification standards, rather than use the results of the DHSA. 11.2 Resources Exclusive of Reserves The Aracoma property contains multiple resource blocks which were not deemed to exhibit reserve potential at the time of the study. These resources, formally identified as resources exclusive of reserves, are in the Upper Chilton, Upper Cedar Grove, Lower Cedar Grove, Alma and No. 2 Gas seams. Reasons which may preclude elevation of resources to reserves include, but are not limited to: 1. Unfavorable geology, mine access or social/political constraint that will increase mine operating cost or capital development costs. a. Map 5, No. 2 Gas seam, shows resource classification for peripheral blocks adjacent to the Rum Creek Area Reserves. Geology indicates the roof and floor will be hard cutting, limiting the mine height and equipment size. 2. Coal quality inconsistent with typical metallurgic properties preferred for coking coal. a. Shown on Map 2, Upper Cedar Grove seam, the Cedar Grove #2 mine experienced higher than desirable Sulfur content when mining in the portions of Block A. Portions of Block A, B and C that are projected to have higher than 1.6% Sulfur, were subsequently designated as resource tons rather than as reserves. Block C was further limited by projected low estimated visual recovery (EVR) caused by seam splitting. b. Map 5, No. 2 Gas seam, shows resource classifications for blocks LB- G, and H, resulting from projected low Fluidity in the Lynn Branch No. 2 mine. Further exploration with subsequent coal analysis with rheological properties is suggested to further delineate the mineable reserve. 3. Isolation of resource blocks in which seam access costs are cost prohibitive at the time of the study. a. Map 7, Chilton Seam, Blocks BW-A1 through BW-A5 and BW-B through BW-F, have all been classified as resource as they are isolated and separated by adverse mineral and out crops. The resources have the potential be both surface mined or underground mined or a combination of the methods. The seam is located high on the hills, so cover is generally shallow and variable. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 36 4. Unfavorable economics at the PFS level, yet economics could become attractive in the future under different market conditions. 5. Exclusion from LOM planning by mining operator due to remaining resource blocks which are relatively small, isolated blocks and not currently attractive from an operational perspective. a. Portions of the Boone West No. 2 Gas, Blocks BW-A, B, B1, D1, D2, and E - on Map 5, located immediately north of the reserve block BW-C, have been designated as resource as they are relatively small, isolated controlled blocks of coal. Additional mineral control with associated exploration drilling could define a contiguous block suitable for mine development. 11.2.1 Initial Economic Assessment MM&A completed an initial economic assessment to determine the potential economic viability of resources exclusive of reserves. MM&A applied relevant technical factors to estimate potential saleable tons without the resource blocks, should the resources be extracted via deep, continuous mining methods. MM&A developed cash cost profiles for the resource blocks, including direct cash costs (labor, supplies, roof control, maintenance and repair, power, and other); washing, trucking, materials handling, general and administrative, and environmental costs; and indirect cash costs (royalties, production taxes, property tax, insurance). Costs were developed based off relevant cost drivers (per-ft, per-raw-ton, per-clean-ton). Additionally, MM&A estimated capital costs to access resources. Capital costs associated with mine development were amortized across the resource’s potential saleable tonnages). Additional non-cash items (depreciation of equipment and depletion) and cash costs were compared to an assumed sale price of $115 per ton netback FOB loadout (approximately $153 per ton U.S. East Coast basis) for high-volatile markets. This resource assumed sales value was developed as a premium to the market-based reserve sales value to properly estimate the sales related expenses should these resources be extracted during higher-than-average market conditions. Pricing used for the primary product was selected by the QP and deemed reasonable based on a review of historical average pricing for the Aracoma complex coal products over the past 5 years. Results of the analysis are shown below and demonstrate potential profitability on a fully loaded cost basis. Detailed summaries are shown in Appendix B.

Note (3): The Property contains 140.66 Mt of dry, in-place measured and indicated coal resources exclusive of reserves as of December 31, 2021. Totals may not add due to rounding. See Appendix A for more detailed breakdown. 11.4 Qualified Person’s Opinion While there is some stratigraphically controlled seam-thickness variability due to seam splitting, sand channels, etc., MM&A geologists and engineers modeled the deposit and resource areas to reflect realistic mining scenarios, giving special consideration to seam thickness, floor and roof conditions, mining equipment, etc. This statistical study demonstrates that for each configuration of mineable seams, the classification system of measured (0 – ¼ mile), indicated (¼ to ¾ mile), and inferred (¾ to 3 miles) is reasonably adequate to predict seam thickness variation for modeling and mining purposes. Based on MM&A’s geostatistical analysis, it would be possible to extend the measured, indicated and inferred arcs slightly beyond historically accepted practices due to consistent geological settings. The QP’s have again elected not to extend arc distances, introducing a level of conservatism in measured and indicated coal classification. Based on the data review, the attendant work done to verify the data integrity and the creation of an independent Geologic Model, MM&A believes this is a fair and accurate representation of the Aracoma coal resources. 12 Mineral Reserve Estimates 12.1 Assumptions, Parameters and Methodology Coal Reserves are classified as proven or probable considering “modifying factors” including mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. > Proven Coal Reserves are the economically mineable part of a measured coal resource, adjusted for diluting materials and allowances for losses when the material is mined. It is based on appropriate assessment and studies in consideration of and adjusted for reasonably assumed modifying factors. These assessments demonstrate that extraction could be reasonably justified at the time of reporting. > Probable Coal Reserves are the economically mineable part of an indicated coal resource, and in some circumstances a measured coal resource, adjusted for diluting materials and allowances for losses when the material is mined. It is based on appropriate assessment and studies in

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 39 consideration of and adjusted for reasonably assumed modifying factors. These assessments demonstrate that extraction could be reasonably justified at the time of reporting. Upon completion of delineation and calculation of coal resources, MM&A generated a LOM plan for Aracoma. The footprint of each reserve area is shown on the maps in Appendix C. The Mine plan was generated based on budget mine plans provided by Alpha and supplemented with additional projections by MM&A to reflect LOM plans that honor property control limits, geologic mapping, or other factors determined during the evaluation. Carlson Mining software was used to generate the LOM plan for Aracoma. The mine plan was sequenced based on productivity schedules provided by Alpha. MM&A judged the productivity estimates and plans to be reasonable based on experience and current industry practice. Raw, ROM production data outputs from LOM plan sequencing were processed into Microsoft® EXCEL spreadsheets and summarized on an annual basis for processing into the economic model. Average seam densities were estimated to determine raw coal tons produced from the LOM plan. Average mine recovery and wash recovery factors were applied to determine coal reserve tons. Coal reserve tons in this evaluation are reported at a 6.0-percent moisture and represent the saleable product from the Property. Pricing data as provided by Alpha is described in Table 16-2. The pricing data assumes a flat-line mine realization of $117 per short ton port pricing, with an average $87.72 per ton netback pricing, reflective of the high-volatile product currently sold at Aracoma. The coal resource mapping and estimation process, described in the report, was used as a basis for the coal reserve estimate. Proven and probable coal reserves were derived from the defined coal resource considering relevant processing, economic (including technical estimates of capital, revenue, and cost), marketing, legal, environmental, socio-economic, and regulatory factors and are presented on a moist, recoverable basis. As is customary in the US, the categories for proven and probable coal reserves are based on the distances from valid points of measurement as determined by the QP for the area under consideration. For this evaluation, measured resource, which may convert to a proven reserve, is based on a ¼-mile radius from a valid point of observation. Points of observation include exploration drill holes, and mine measurements which have been fully vetted and processed into a geologic model. The geologic model is based on seam depositional modeling, the interrelationship of overlying and underlying strata on seam mineability, seam thickness trends, the impact of seam structure, intra-seam characteristics, etc. Once the geologic model was completed, a statistical analysis, described in Section 11.1.1 was conducted and a ¼-mile radius from a valid point of observation was selected to define Measured Resources. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 40 Likewise, the distance between ¼ and ¾ of a mile radius was selected to define Indicated Resources. Indicated Resources may convert to Probable Reserves. Inferred Resources (greater than a ¾-mile radius from a valid point of observation) have been excluded from Reserve consideration. 12.2 Mineral Reserves Aracoma reserves were derived from multiple coal seams of Figure 7-1 located on the Property. All reserves are planned to be mined by underground mining methods. The above-drainage underground seams include the Upper Chilton seam at Davey Branch and Hatfield and the Upper Cedar Grove seam at Laurel Branch Mine. Below-drainage underground reserves are in the Lower Cedar Grove seam, the Alma seam at Beech Branch and the No. 2 Gas seam at Boone West, Lynn Branch and Rum Creek. Table 12-1 shows the demonstrated tonnage by Proven and Probable. 12.2.1 Upper Chilton Seam The Upper Chilton reserve are contained in two blocks, the active Day Branch mine block and, to the west, the Hatfield block. Seam thickness is generally between 3 and 4 feet. Localized areas of hard roof and floor are excluded from the reserves. 12.2.2 Upper Cedar Grove Seam The Upper Cedar Grove resource is also in two blocks, the active Cedar Grove No. 2 mine block and a separate block to the west. The reserve is defined by areas with less than 1.60% sulfur and greater than 50% inseam yield, as an estimated visual recovery. There are no reserves defined in the active Cedar Grove No. 2 mine block, all reserve is in the west block (Laurel Branch). 12.2.3 Lower Cedar Grove Seam The Lower Cedar Grove reserve is in an unmined block surrounded by abandoned mines. Access would be through a short slope. Seam thickness ranges from 2.50 to 3.50 feet. 12.2.4 Alma Seam Alma seam reserve is located in one block south of the Guyandotte River and the closed Aracoma Alma No.1 Mine. The east side of the reserve block outcrops along the river and the west side with reserve access is below drainage. The seam thickness is less than 3.0 feet, and the reserve cutoff is 2.5 feet. 12.2.5 No. 2 Gas Seam The No. 2 Gas seam reserve is in three areas: the active Lynn Branch No. 2 Mine, the Rum Creek area and the Boone West area. Lynn Branch is the largest block of the No. 2 Gas reserve and is located south of the Guyandotte river and south and west of previous mining. Seam thickness is generally greater than 3 feet. Areas with projected low fluidity are excluded from the reserve. The Run Creek reserve is

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 41 north of the Guyandotte River and along the north margin of abandoned mine workings. The seam splits to the north and the reserve area is bound by hard roof and floor rock that will limit the mining height. The Boone West reserve is north of Rum Creek. The reserve outcrops on the west side in Mill and Crooked Creeks. 12.3 Qualified Person’s Estimates The coal reserves, as shown in Table 12-1, are based on a technical evaluation of the geology and a preliminary feasibility study of the coal deposits. The extent to which the coal reserves may be affected by any known environmental, permitting, legal, title, socio-economic, marketing, political, or other relevant issues has been reviewed rigorously. Similarly, the extent to which the estimates of coal reserves may be materially affected by mining, metallurgical, infrastructure and other relevant factors has also been considered. The results of this TRS define an estimated 44.18 Mt of proven and probable marketable coal reserves. The maps included in Appendix C reflect mining depletion at the time of the resource/reserve calculation taken from Alpha mine maps at various points during calendar year 2021. Mine depletion tonnages were supplied by Alpha through the end of 2021, and MM&A deducted this historical production from the mapped reserves in order to estimate reserves as of December 31, 2021.

Coal quality is based on a weighted average of laboratory data from core holes The combination of surface and inherent moisture is modeled at 6.0-percent. Actual product moisture is dependent upon multiple geological factors, operational factors, and product contract specifications and can exceed 8-percent. As such, the modeled moisture values provide a level of conservatism for reserve reporting. *Volatile Matter analysis is not available for all reserve areas. All Aracoma reserves are priced as a High-Vol. B product. Totals may not add due to rounding. See Appendix A for more detailed breakdown. 12.4 Qualified Person’s Opinion The estimate of coal reserves was determined in accordance with the new SEC Guidelines which will become effective for the first fiscal year falling on or after January 1, 2021. The LOM mining plan for Aracoma was prepared to the level of preliminary feasibility. Mine projections were prepared, and timing scheduled to match production with coal seam characteristics. Production Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 42 timing was carried out from current locations to depletion of the coal reserve area. Coal reserve estimates could be materially affected by the risk factors described in Section 22.2. Based on the Preliminary Feasibility Study and the attendant Economic Review, MM&A believes this is a fair and accurate calculation of the Aracoma coal reserves. 13 Mining Methods Three underground mining areas were modeled and tested economically. Once the Resources were calculated, mine plans were created to project operating each resource area to depletion, with crews and equipment scheduled to move to subsequent mining areas as depletion occurs. Underground mine operations are projected to be exhausted in 2047. Individual mine lives range from 4 to 17 years. 13.1 Geotech and Hydrology Mining plans for potential underground mines were developed by Alpha and MM&A. Pillar stability was tested by MM&A using the Analysis of Coal Pillar Stability (ACPS) program that was developed by NIOSH. MM&A reviewed the results from the ACPS analysis and considered it in the development of the LOM plan. Hydrology has not been an issue of concern at Aracoma. Based on numerous site visits to the underground operations of the property by the QP’s, it has been determined that this is not a significant concern. Mining of future reserves is projected to occur in areas which exhibit similar hydrogeological characteristics as those formerly mined areas. 13.2 Production Rates Operations at Aracoma by Alpha and its predecessors have been on-going for many years. The Mine plan and productivity expectations reflect historical performance and efforts have been made to adjust the plan to reflect future conditions. MM&A is confident that the mine plan is reasonably representative to provide an accurate estimation of coal reserves. Mine development and operation have not been optimized within the TRS. Carlson Mining software was used by MM&A to generate mine plans for the mineable coal seams. Mine plans were sequenced based on productivity schedules provided by Alpha, which were based on historically achieved productivity levels. All production forecasting ties assumed production rates to geological models as constructed by MM&A’s team of geologists and mining engineers. The Aracoma Mining Complex currently operates three underground mines with a total of seven (7) operating sections. The Cedar Grove #2 mine is phasing out of production as reserves deplete and the units are being introduced into Lynn Branch No. 2 Mine. The Aracoma Alma mine recently closed with

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 43 these units transitioning into similar conditions at the Lynn Branch No. 2 (No. 2 Gas seam) and Davy Branch (Upper Chilton seam) mines. The projected underground mines are set up similarly to the currently active operation. Lynn Branch No. 2 will operate three production sections and the Davy Branch Mine will operate two production sections. All sections are configured with dual continuous miners in a super section operation. In all cases, mines are forecasted to produce coal two shifts each day. Production is scheduled Monday through Friday each week, and every other Saturday. As shown in Table 13-1, the three areas planned for underground mines produce coal until 2047. Clean coal production varies directly with coal thickness.

For each mine plan, the appropriate number of production units is selected for the resource area, and a productivity level assigned, expressed in feet of advance per unit-shift of production. The productivity is based on the equipment and personnel configuration, mining height and expected physical conditions. 13.4 Required Equipment and Personnel 13.4.1 Underground Mines 13.4.1.1 Lynn Branch No. 2 Mine (Map 5) The Lynn Branch No. 2 Mine, which is in the early development stage, is currently operating three (3) continuous mining sections producing from the No. 2 Gas seam. This mine produces metallurgical coal from leased mineral property. The mine started its first mining unit in 2020, the second in March of 2021 and the third unit in July 2021. Production is scheduled for approximately 265 days each year, which represents production on Monday through Friday plus every other Saturday. On each day, production sections are scheduled to produce coal on two shifts. The sections are configured as super sections with two continuous miners used for production on each section. Productivity is planned at the rate of 240 feet of advance per shift of operation. Principal production equipment per section includes two continuous miners, two roof bolters, four shuttle cars, and one scoop. Coal is extracted from the production face with the continuous miners and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is stockpiled. Coal is then transported via highway truck haulage to the Bandmill Preparation Plant where it is processed and loaded onto CSX rail for transport to the consumer. The Lynn Branch No. 2 Mine is operational at the time of this report; all necessary infrastructure and utilities are in place; all necessary permits have been obtained. Estimated expenditures for site closure and reclamation are included in the financial model for this site. The mine is scheduled to deplete its mining assignment in 2038. 13.4.1.2 Davy Branch Deep Mine (Map 1) The Davy Branch Deep Mine, which is currently operational with two (2) continuous mining sections producing coal in the Upper Chilton seam on leased mineral property. The Davy Branch Deep Mine is

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 45 a two (2) section mine with each working section operated as a super section (two sets of mining equipment operating simultaneously and sharing a common dumping point on the same section, with each set being ventilated by a separate split on intake air) Each super section operates two (2) Continuous Miners, two (2) Roof Bolters, four (4) Shuttle Cars and one (1) scoop. Like the Lynn Branch No. 2 Deep mine operation, coal is extracted from the production face with the continuous miners and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is stockpiled. Coal is then transported via highway truck haulage to the Bandmill Preparation Plant where it is processed and loaded into CSX rail for transport to the consumer. The Davy Branch Deep Mine is also operational at the time of this report with all necessary infrastructure and utilities in place. All necessary permits have been obtained. Estimated expenditures for site closure and reclamation are included in the financial model for this site. The mine is scheduled to deplete its mining assignment in 2028. 13.4.1.3 Cedar Grove #2 (Map 2) Active at the time of this report, the Cedar Grove #2 Mine in the Upper Cedar Grove seam, is nearing completion with an estimated depletion date of first quarter 2023. The mine produces metallurgical grade coal using two (2) active sections with one (1) continuous miner, one (1) roof bolter, two (2) shuttle cars, one (1) belt feeder, and one (1) scoop per section. Coal is extracted from the production face with the continuous miners and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is processed by the Bandmill preparation plant. Due to the favorable fluidity of this coal, a key factor in determining the coking quality of coal, Alpha uses coal produced from this mine to blend coal from other Alpha mining operations which may show slightly less favorable coking characteristics. Alpha is actively conducting exploration in adjacent Upper Cedar Grove resources to determine the true extent of the mineable reserves. 13.4.1.4 Hatfield Upper Chilton (Map 1) The Hatfield Upper Chilton reserve is in conceptual stage at this point. A potential portal area was located along the outcrop near County Highway 13. The reserve can support two operating areas for two continuous miner production sections. The physical location of the reserve is the furthest from the Bandmill preparation plant with a highway haul of 21.5 miles. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 46 The report includes an initial starting date in 2027 with a second production unit starting in 2029. One continuous mining production unit will deplete its assignment in 2036 and the second production unit would deplete its assignment in 2038. 13.4.1.5 Rum Creek No. 2 Gas (Map 5) Currently in the inception stage, the Rum Creek mine will potentially operate in Blocks RC-A, RC-B, RC- C, RC-D, RC-E and RC-G. Careful mine planning will require considerations for seam splitting, as well as cuttability issues presented by simultaneous hard roof and hard floor conditions. Utilizing available drilling data, MM&A identified on Map 5 areas as “full seam” where the parting between the Upper and Lower No. 2 Gas seam benches is less than three feet in thickness allowing both benches to feasibly be mined together as one mining sequence. The areas identified as “Main Bench” have inseam parting thickness of greater than 3 feet in thickness, thereby limiting mining to the upper bench of the No. 2 Gas seam in Blocks RC-A, RC-C, RC-E and RC-G. Evaluation of drilling records revealed the potential for sandstone roof and floor lithologies to exist simultaneously in Blocks RC-F and RC-K. At the time of this report, planned mining equipment is limited to a 54-inch minimum cutting height. Block-RC-A and RC-C having a seam thickness of less than 54 inches and show the potential for simultaneous hard roof and floor, have therefore been designated as resource. Structural mapping of the No. 2 Gas bottom of coal elevation revealed an anticline, a fold of rock layers that slope downward on both sides of a crest. Due to potential mining encumbrances from a 10% gradient, Block RC-H is designated as resource. Conceptual mining is projected to commence in 2035 and be completed in 2043. 13.4.1.6 Boone West (No. 2 Gas) This reserve area is located north of the Bandmill Preparation Plant. A contour faceup would be used to access the coal seam. The reserve block can support two continuous miner units. The property has had limited mining activity with no undermining and limited overmining. Peach Creek Road - County Route 12/02 comes directly to the proposed stockpile area. The County Road is a paved road, but only one lane wide traveling through populated areas. The distance to the preparation plant is 13.5 miles. The report includes an initial starting date in 2037 with a second production unit starting in the same year. Both continuous mining production units will deplete their assignments in 2044.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 47 13.4.1.7 Upper Cedar Grove #3 This reserve area has been defined by the sulfur isopach at a cut point of 1.60% sulfur in the projected clean product. The mine would be a one section operation and would start in 2039 and deplete in 2042. The projected faceup from a contour bench is located along West Virginia Route 10, which has been upgraded as a divided 4-lane highway. Haul distance to the Bandmill Preparation Plant is 5.0 miles. 13.4.1.8 Alma Seam at Beech Branch This reserve area is a small block that can be accessed from an outcrop portal. The mining has been projected as a single production unit. Mining would begin in 2039 and the reserve would be depleted in 2042. The projected faceup from a contour bench is located along West Virginia Route 10, which has been upgraded as a divided 4-lane highway. Haul distance to the Bandmill Preparation Plant is 4.7 miles. 13.4.1.9 Lower Cedar Grove – Hatfield Area This reserve area is a small block that would be accessed from an abandoned mine bench. The mine would face up in the Upper Split of the Lower Cedar Grove Seam and then ramp down in the Lower Cedar Grove Seam. This mine would support two continuous miner units with both starting in 2043 and the first finishing in 2046 and the second in 2047. Run of Mine Coal would be trucked via County Route 13 to the Bandmill Preparation Plant located 18.9 miles away. 14 Processing and Recovery Methods 14.1 Description or Flowsheet The Aracoma Division currently includes the Bandmill Preparation Plant in addition to the mines. The plant site includes raw coal storage, clean coal storage, a centrifugal dryer, a railroad loadout, and refuse disposal area. Feed rate capacity is 1200 raw tons per hour and produces a typical product containing 7.31% ash, 1.00% sulfur and 37.02% volatile matter. Primary separation equipment includes heavy media vessels, heavy media cyclones, spirals, and flotation cells, supported by the requisite screens, centrifuges, disk filters, plate presses, sumps, pumps, and distribution systems. For year end 2021 the average utilization rate of the Bandmill Preparation Plant was 60.4%. Additional plate presses have recently been installed to reduce the amount of slurry. Coarse and fine refuse are disposed in an adjacent combined fill refuse area and impoundment. Processes and equipment are typical of those used in the coal industry and are in use in nearly all plants in the Central Appalachian Basin. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 48 14.2 Requirements for Energy, Water, Material and Personnel Personnel have historically been sourced from the surrounding communities in Logan, Mingo, Wyoming, and Boone Counties, and have proven to be adequate in numbers to conduct processing operations at Aracoma. As mining is common in the surrounding areas, the workforce is generally familiar with mining practices, and many are experienced miners. Water is sourced locally from public water sources or rivers, and electricity is sourced from AEP. The service industry in the areas surrounding the mine complex has historically provided supplies, equipment repairs and fabrication, etc. 15 Infrastructure Alpha’s Bandmill preparation plant services the area with washed coal, which is transported via the CSX rail line at the plant’s loadout. Haul roads, primary roads, and conveyor belt systems account for transport from the various mine sites to the preparation plant. This practice will continue for future reserves. As an active operation, the necessary support infrastructure for Aracoma is in place. As new areas are developed, the infrastructure requirements will change. These changes have been considered in the LOM plans and financial model. The underground mining resource areas which are located above drainage will require an access road and mine access development along the outcrop. Typical mine facilities include a mine office, a change house, supply facilities, mine fan and a stacker conveyor if truck haulage is required. A Photo of the existing facilities is shown in Figures 15-1 and 15-2.

The drill hole data were utilized to develop average coal quality characteristics for the mining site. These average coal quality characteristics were then utilized as the basis for determining the various markets into which the saleable coal will likely be placed. Quality Specifications for the Aracoma High-Volatile B product is as shown in Table 16-1. Table 16-1: Quality Specifications 2021 Ash (%) 7.06 Sulfur (%) 0.93 Volatile Matter (%) 37.04 The mine production primarily serves the high-volatile metallurgical markets with lesser by-product PCI and thermal coal. 16.2 Price Forecasts Company-wide pricing data as provided by Alpha is described in Table 16-2. Note that not all products reflected in Table 16-2 will apply to every business unit. The pricing data assumes a flat-line long-term realization of $117 per short ton port pricing, with an average $87.72 per ton netback pricing reflective of the high-volatile product currently sold at Aracoma. These estimates are based on long-term pricing published by third party sources and adjusted for quality and transportation. The netback pricing represents adjustments made to published benchmark pricing based on quality and transportation. A large majority of the coal sold by Alpha is shipped internationally as part of blended products from other business units within Alpha or sourced from other companies. These netback adjustments reflect these additional costs carried after the products leave the Aracoma business unit.

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 51 16.3 Contract Requirements Some contracts are necessary for successful marketing of the coal. For Aracoma, since all mining, preparation and marketing is done in-house, the remaining contracts required are: > Transportation – Alpha contracts with the CSX Railroad to transport coal to market > Sales – Sales contracts are a mix of spot and contract sales. With the volatility of the market, long- term contracts are not typically written. 17 Environmental Studies, Permitting and Plans, Negotiations or Agreements with Local Individuals 17.1 Results of Studies MM&A completed an environmental review in 2011 of the Massey properties acquired by Alpha, including those operations that were active at Aracoma at that time. The environmental review completed by MM&A included site inspections, reviews of historical records, database searches of State and Federal regulatory records and interviews to identify potential recognized environmental conditions (RECs) that may create environmental liability for the sites. While MM&A identified RECs during both studies, MM&A’s opinion was that those issues would not preclude the continued or future use of the properties as a coal mining/preparation venture. Based on this former ESA completed by MM&A, it is MM&A’s opinion that Aracoma has a generally typical coal industry record of compliance with applicable mining, water quality, and environmental laws. Estimated costs for mine closure, including water quality monitoring during site reclamation, are included in the financial models. 17.2 Requirements and Plans for Waste Disposal Based on a recent engineering review, done by Alpha, approximately 23.5 to 26.5 years of fine and coarse refuse disposal capacity at current rates have been identified, approximately 5 years is permitted and active. A 10-foot crest raise expansion at the Tinsley Branch slurry impoundment is approved by West Virginia Department of Environmental Protection (WVDEP) and in review by the Mine Safety and Health Administration (MSHA). The Bandmill Hollow Combined Refuse Fill is approved by WVDEP and MSHA and is under review by the U.S. Army Corps of Engineers (ACOE). Securing additional coarse and fines capacity will be critical to execute the business plan as outlined in this TRS. The table below outlines the current estimated capacities and permits of Aracoma’s fine and coarse impoundments. Alpha Metallurgical Resources, Inc.

Permits generally require that the permittee post a performance bond in an amount established by the regulatory program to provide assurance that any disturbance or liability created during mining operations is properly restored to an approved post-mining land use and that all regulations and requirements of the permits are fully satisfied before the bond is returned to the permittee. Significant penalties exist for any permittee who fails to meet the obligations of the permits including cessation of mining operations, which can lead to potential forfeiture of the bond. Any company, and its directors, owners and officers, which are subject to bond forfeiture can be denied future permits under the program.1 New permits or permit revisions will occasionally be necessary to facilitate the expansion or addition of new mining areas on the Property, such as amendments to existing permits and new permits for mining of reserve areas. Exploration permits also are required. Property under lease includes provisions for exploration among the terms of the lease. New or modified mining permits are subject to a public advertisement process and comment period, and the public is provided an opportunity to raise objections to any proposed mining operation. MM&A is not aware of any specific prohibition of mining on the subject property and given sufficient time and planning, Alpha should be able to secure new permits to maintain its planned mining operations within the context of current regulations. Necessary permits are in place to support current production on the Property, but future permits are required to maintain and expand production. Portions of the Property are located near local communities. Regulations prohibit mining activities within 300 feet of a residential dwelling, school, church, or similar structure unless written consent is first obtained from the owner of the structure. 1 Monitored under the Applicant Violator System (AVS) by the Federal Office of Surface Mining.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 53 Where required, Alpha reports that such consents have been obtained where mining is proposed beyond the regulatory limits. Alpha has obtained all mining and discharge permits to operate its mines and processing, loadout or related facilities. MM&A is unaware of any obvious or current Alpha permitting issues that are expected to prevent the issuance of future permits. Aracoma, along with all coal producers, is subject to a level of uncertainty regarding future clean water permits due to United States Environmental Protection Agency (EPA) involvement with state programs. The mining permits currently held by Aracoma are shown in Table 17-2.

In general, site reclamation includes removal of structures, backfilling, regrading, and revegetation of disturbed areas. For surface mines, the majority of the expense for backfilling and regrading is completed as part of ongoing mining operations, with only reclamation of final pits and HWM benches required at end-of-mine life. Sediment control is required during the establishment of vegetation, and bond release generally requires a minimum five-year period of site maintenance, water sampling, and sediment control following mine completion. This requirement is reduced to two years for certain operations involving re-mining. Reclamation of underground mines includes closure and sealing of mine openings such as portals and shafts in addition to the items listed above. Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 54 Estimated costs for mine closure, including water quality monitoring during site reclamation, are included in the financial models. As with all mining companies, an accretion calculation is performed annually so the necessary Asset Retirement Obligations (ARO) can be shown as a Liability on the Balance Sheet. 17.6 Qualified Person’s Opinion The Aracoma complex is an operating facility; all necessary permits for current production have been obtained. MM&A knows of no reason that any permits revisions that may be required cannot be obtained. Estimated expenditures for site closure and reclamation are included in the financial model for this site. 18 Capital and Operating Costs 18.1 Capital Cost Estimate The production sequence selected for a property must consider the proximity of each reserve area to coal preparation plants, river docks and/or railroad loading points, along with suitability of production equipment to coal seam conditions. The in-place infrastructure was evaluated, and any future needs were planned to a level suitable for a Preliminary Feasibility Study and included in the Capital Forecast. Alpha provided MM&A with information related to the number of currently operating production units at Aracoma. MM&A’s capital schedules assume that major equipment rebuilds occur over the course of each machine’s remaining assumed operating life. Replacement equipment was scheduled based on MM&A’s experience and knowledge of mining equipment and industry standards with respect to the useful life of such equipment. As one mine is depleted, the equipment is moved to its replacement. The capital expenditures tables detail costs for major equipment and infrastructure such as conveyor belt terminal groups. “Other” costs include expenditures for mine access and construction, mine extension capital and miscellaneous costs. A summary of the estimated capital for the consolidated Aracoma operations is provided in Figure 18-1 below. Total capital by mine is summarized in Table 18- 1.

MM&A used the historical and/or budget cost information as a reference and developed a personnel schedule for the mine. Hourly labor rates and salaries were based upon information contained in Alpha’s financial summaries. Fringe benefit costs were developed for vacation and holidays, federal and state unemployment insurance, retirement, workers’ compensation and pneumoconiosis, casualty and life insurance, healthcare and bonuses. A cost factor for mine supplies was developed that relates expenditures to mine advance rates for roof control costs and other mine supply costs based on the historical cost data provided by Alpha. Other factors were developed for maintenance and repair costs, rentals, mine power, outside services, coal preparation plant processing, refuse handling, coal loading, property taxes, and insurance and bonding and other direct mining costs. Appropriate royalty rates were assigned for production from leased coal lands and sales taxes were calculated for state severance taxes, the federal black lung excise tax, and federal and state reclamation fees. Statutory sales related costs are summarized in Table 18-2. Table 18-2: Estimated Coal Production Taxes and Sales Costs Description of Tax or Sales Cost Basis of Assessment Cost Federal Black Lung Excise Tax - Underground Per Ton $1.10 Federal Reclamation Fees – Underground Per Ton $0.12 West Virginia Reclamation Tax - Underground Per Ton $0.279 West Virginia Severance Tax Percentage of Revenue 1 to 5% Royalties - Underground Percentage of Revenue 6.0% Notes: 1. Federal black lung excise tax is paid only on coal sold domestically. MM&A assumed 50% of sales will be into domestic market.

Figure 18-2: Aracoma Operating Costs 19 Economic Analysis 19.1 Economic Evaluation 19.1.1 Introduction The pre-feasibility financial model prepared for this TRS was developed to test the economic viability of each coal resource area. The results of this financial model are not intended to represent a bankable feasibility study, required for financing of any current or future mining operations contemplated for the Alpha properties, but are intended to establish the economic viability of the estimated coal reserves. Cash flows are simulated on an annual basis based on projected production from the coal reserves. The discounted cash flow analysis presented herein is based on an effective date of January 1, 2022. On an un-levered basis, the NPV of the project cash flow after taxes represents the Enterprise Value of the project. The project cash flow, excluding debt service, is calculated by subtracting direct and indirect operating expenses and capital expenditures from revenue. Direct costs include labor, operating supplies, maintenance and repairs, facilities costs for materials handling, coal preparation, Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 58 refuse disposal, coal loading, reclamation and general and administrative costs. Indirect costs include statutory and legally agreed upon fees related to direct extraction of the mineral. The indirect costs are the Federal black lung tax, Federal and State reclamation taxes, property taxes, coal production royalties, and income taxes. The Alpha mines’ historical costs provided a useful reference for MM&A’s cost estimates. The operations are projected on a calendar year basis. MM&A’s projection of annual sales tonnage is summarized in the chart below. While all Alpha coal resources properties deemed by MM&A to have potential for classification as coal reserves were evaluated as part of the economic model, some of those resource areas were determined to be uneconomical in the current market and were therefore excluded from coal reserves as discussed below. Figure 19-1: Projection of Sales Tons Sales revenue is based on the metallurgical coal price information provided to MM&A by Alpha. Only the revenue from Alpha’s captive mining operations is included in the financial model used for this TRS. The P&L projections of the individual mines of Alpha’s Aracoma operations are then consolidated into a P&L and cash flow schedule for further testing of the economics. Projected debt service is excluded from the P&L and cash flow model in order to determine Enterprise Value of the aggregated entity.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 59 The financial model expresses coal sales prices, operating costs, and capital expenditures in current day dollars without adjustment for inflation. Capital expenditures and reclamation costs are included based on engineering estimates for each mine by year. MM&A also included an estimate of administrative costs in the financial projections. Alpha will pay royalties for the various current and projected operations. The royalty rates vary by location as provided by Alpha. The royalty rates were assumed to be 6.0% of the sales revenue. The projection model also includes consolidated income tax calculations at Alpha’s Aracoma Division level, incorporating statutory depletion calculations, as well as state income taxes, and a federal tax rate of 21%. To the extent the Alpha mines generate net operating losses for tax purposes, the losses are carried over to offset future taxable income from Alpha mines. The terms “cash flows” and “project cash flows” used in this report refer to after-tax cash flows. Alpha’s projected consolidated annual revenue for the Aracoma operations is shown in the chart below: Figure 19-2: Consolidated Annual Revenue Projected consolidated revenue, cash costs, and EBITDA for the Aracoma operations are expressed in dollars per ton in the graph below.

LOM tonnage evaluated in the financial model includes 4th quarter 2021 production (500,817 clean tons) which was subtracted from coal reserves in order to make the effective date of the reserves December 31, 2021. Consolidated cash flows are driven by annual sales tonnage, which peaks at 2.2 million tons in 2022. Between years 2023 and 2043, sales ranges from 1.5 million to 2.1 million tons and between years 2044-2047, sales range from 0.3 million tons to 1.1 million tons. Projected consolidated revenue peaks at $194.6 million in 2022 and totals $3.9 billion for the project’s life. Consolidated cash flow from operations is positive throughout the projected operating period, with the exception of post-production years, due to end-of-mine reclamation spending. Consolidated cash flow from operations peaks at $52.1 million in 2023 and totals $827.0 million over the project life. Capital expenditures total $57.0 million during the first five years and $230.5 million over the project’s life. Consolidated Aracoma net cash flow after tax, but before debt service, is shown by year in the chart below:

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 63 Figure 19-5: Net Cash Flow after Tax (Before Debt Service) LOM Net cash flow is positive for this project. The cash flows after year 2047 are generally related to end of mine reclamation expenditures, which are accrued over the life of the mines. 19.1.3 Discounted Cash Flow Analysis Cash flow after tax, but before debt service, generated over the life of the project was discounted to NPV at a 14.67% discount rate, which represents MM&A’s estimate of the constant dollar, risk adjusted WACC for likely market participants if the subject reserves were offered for sale. On an un-levered basis, the NPV of the project cash flows represents the Enterprise Value of the project and amounts to $221.8 million. Alpha is an active producer, and the financial model shows positive net cash flow for each year of the operating life of the Aracoma reserves. The pre-feasibility financial model prepared for the TRS was developed to test the economic viability of each coal resource area. The NPV estimate was made for purposes of confirming the economics for classification of coal reserves and not for purposes of valuing Alpha or its Aracoma assets. Mine plans were not optimized, and actual results of the operations may be different, but in all cases, the mine production plan assumes the properties are under competent management. 19.1.4 Sensitivity Analysis Sensitivity of the NPV results to changes in the key drivers is presented in the chart below. The sensitivity study shows the NPV at the 14.67% discount rate when Base Case sales prices, operating Alpha Metallurgical Resources, Inc.

Figure 19-6: Sensitivity of NPV As shown, NPV is quite sensitive to change in sales price and operating cost estimates, and slightly sensitive to changes in capital cost estimates. 20 Adjacent Properties 20.1 Information Used No Proprietary information associated with neighboring properties was used as part of this study. 21 Other Relevant Data and Information MM&A performed a previous audit of all the Property in year 2020 for Alpha based on U.S. Securities and Exchange Commission (SEC) Industry Guide 7 standards. MM&A utilized this former audit study as the basis of an updated study which meets those standards set forth by the SEC for 2021 reserve compliance.

Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 65 22 Interpretation and Conclusions 22.1 Conclusion Sufficient data has been obtained through various exploration and sampling programs and mining operations to support the geological interpretations of seam structure and thickness for coal horizons situated on the Aracoma Property. The data is of sufficient quantity and reliability to reasonably support the coal resource and coal reserve estimates in this TRS. The geological data and preliminary feasibility study, which consider mining plans, revenue, and operating and capital cost estimates are sufficient to support the classification of coal reserves provided herein. This geologic evaluation conducted in conjunction with the preliminary feasibility study is sufficient to conclude that the 44.18 Mt of marketable coal reserves identified on the Property are economically mineable under reasonable expectations of market prices for metallurgical coal products, estimated operation costs, and capital expenditures. 22.2 Risk Factors Risks have been identified for operational, technical and administrative subjects addressed in the Pre- Feasibility Study. A risk matrix has been constructed to present the risk levels for all the risk factors identified and quantified in the risk assessment process. The risk matrix and risk assessment process are modelled to that presented in the Australian and New Zealand Standard on Risk Management (AS/NZS 4360). The purpose of the characterization of the project risk components is to inform the project stakeholders of key aspects of the Alpha projects that can be impacted by events whose consequences can affect the success of the venture. The significance of an impacted aspect of the operation is directly related to both the probability of occurrence and the severity of the consequences. The initial risk for a risk factor is herein defined as the risk level after the potential impact of the risk factor is addressed by competent and prudent management utilizing control measures readily available. Residual risk for a risk factor is herein defined as the risk level following application of special mitigation measures if management determines that the initial risk level is unacceptable. Initial risk and residual risk can be quantified numerically, derived by the product of values assigned to probability and consequence ranging from very low risk to very high risk. The probability and consequence parameters are subjective numerical estimates made by practiced mine engineers and managers. Both are assigned values from 1 to 5 for which the value 1 represents the lowest probability and least consequence, and the value 5 represents the highest probability and Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 66 greatest consequence. The products, which define the Risk Level, are classified from very low to very high. Risk Level Table (R = P x C) Risk Level (R) Very Low (1 to 2) Low (3 to 5) Moderate (6 to 11) High (12 to 19) Very High (20 to 25) Risk aspects identified and evaluated during this assignment total 13. No residual risks are rated Very High. Three (3) residual risks are rated High. Six (6) of the risk aspects could be associated with Moderate residual risk. Four (4) of the risk aspects were attributed Low or Very Low residual risks. 22.2.1 Governing Assumptions The listing of the aspects is not presumed to be exhaustive. Instead that listing is presented based on the experiences of the contributors to the TRS. 1. The probability and consequence ratings are subjectively assigned, and it is assumed that this subjectivity reasonably reflects the condition of the active and projected mine operations. 2. The Control Measures shown in the matrices presented in this chapter are not exhaustive. They represent a condensed collection of activities that the author of the risk assessment section has observed to be effective in coal mining scenarios. 3. Mitigation Measures listed for each risk factor of the operation are not exhaustive. The measures listed, however, have been observed by the author to be effective. 4. The monetary values used in ranking the consequences are generally accepted quantities for the coal mining industry. 22.2.2 Limitations The risk assessment proposed in this report is subject to the limitations of the information currently collected, tested, and interpreted at the time of the writing of the report. 22.2.3 Methodology The numerical quantities (i.e., risk levels) attributable to either “initial” or “residual” risks are derived by the product of values assigned to probability and consequence ranging from very low risk to very high risk.

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 67 R = P x C Where: R = Risk Level P = Probability of Occurrence C = Consequence of Occurrence The Probability (P) and Consequence (C) parameters recited in the formula are subjective numerical estimates made by practiced mine engineers and managers. Both P and C are assigned integer values ranging from 1 to 5 for which the value 1 represents the lowest probability and least consequence, and the value 5 represents the highest probability and greatest consequence. The products (R = P x C) which define the Risk Level, are thereafter classified from very low to very high. Risk Level Table Risk Level (R) Very Low (1 to 2) Low (3 to 5) Moderate (6 to 11) High (12 to 19) Very High (20 to 25) Very high initial risks are considered to be unacceptable and require corrective action well in advance of project development. In short, measures must be applied to reduce very high initial risks to a tolerable level. As shown and discussed above, after taking into account the operational, technical, and administrative actions that have been applied or are available for action when required, the residual risk can be determined. The residual risk provides a basis for the management team to determine if the residual risk level is acceptable or tolerable. If the risk level is determined to be unacceptable, further actions should be considered to reduce the residual risk to acceptable or tolerable levels to provide justification for continuation of the proposed operation. 22.2.4 Development of the Risk Matrix Risks have been identified for the technical, operational, and administrative subjects addressed in the TRS. The risk matrix and risk assessment process are modelled to that presented in the Australian and New Zealand Standard on Risk Management (AS/NZS 4360). Alpha Metallurgical Resources, Inc.

Risk reduction measures must be applied to reduce very high risks to a tolerable level. 22.2.6 Description of the Coal Property The Aracoma Mine Complex (Aracoma) is located in Logan, Mingo, Boone and McDowell Counties, West Virginia – is an active operation with three underground mines. The active underground operations within the Aracoma Mine Complex (Lynn Branch #2, Davy Branch Deep Mine, and Cedar Grove #2) utilize continuous mining production sections. The method provides continuity, preserving skilled work

Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 71 groups and enabling effective utilization of production equipment. The active and projected mines are located above and below drainage and as such are accessed via a combination of drifts and box cuts. 22.2.7 Summary of Residual Risk Ratings Each risk factor is numbered, and a risk level for each is determined by multiplying the assigned probability by the assigned consequence. The risk levels are plotted on a risk matrix to provide a composite view of the Alpha risk profile. The average risk level is 6.6, which is defined as Moderate. Table 22-4: Risk Assessment Matrix C o n se q u en ce Critical >$50 MM Major $10-50MM 9 6 Moderate $2-10 MM 1, 12 2, 4, 8, 14 3 Minor $0.5-$2 MM 13 5, 7, 10 Low <$0.5 MM 11 <10% 10-30% 30-60% 60-90% >90% Remote Unlikely Possible Likely Almost Certain 22.2.8 Risk Factors A high-level approach is utilized to characterize risk factors that are generally similar across a number of the active and proposed mining operations. Risk factors that are unique to a specific operation or are particularly noteworthy are addressed individually. 22.2.8.1 Geological and Coal Resource Coal mining is accompanied by risk that, despite exploration efforts, mining areas will be encountered where geological conditions render extraction of the resource to be uneconomic, or that coal quality characteristics disqualify the product for sale into target markets. Offsetting the geological and coal resource risk are the size of the controlled property which allows flexibility in the selection of mine areas away from areas where coal quality and mineability are less favorable. In addition, many of the underground mines are designed to operate with multiple production sections each, which lessens the immediate impact when one section encounters difficulties. The large reserve areas also provide a mitigation strategy of varying the timing of Alpha Metallurgical Resources, Inc. Statement of Coal Resources and Reserves for the Aracoma Complex in Accordance with United States SEC Standards as of December 31, 2021 Central Appalachian Coal Basin West Virginia, USA MARSHALL MILLER & ASSOCIATES, INC. 72 development of mines to offset expected or encountered adverse conditions, thereby maintaining consistent production and quality. This flexibility requires additional extension or development cost but increases performance consistency. The larger reserve areas will be developed with multiple production sections and the small, replacement production reserve areas provide ready access to alternative locations if geological and coal resource characteristics require abandonment of an active production area. Table 22-5: Geological and Coal Resource Risk Assessment (Risks 1 and 2) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Recoverable coal tons recognized to be significantly less than previously estimated. Reserve base is adequate to serve market commitments and respond to opportunities for many years. Local adverse conditions may increase frequency and cost of production unit relocations. Previous and ongoing exploration and extensive regional mining history provide a high level of confidence of coal seam correlation, continuity of the coal seams, and coal resource tons. 1 4 4 Optimize mine plan to increase resource recovery; develop mine plan to provide readily available alternate mining locations to sustain expected production level. 1 3 3 Coal quality locally proves to be lower than initially projected. If uncontrolled, production and sale of coal that is out of specification can result in rejection of deliveries, cancellation of coal sales agreements and damage to reputation. Exploration and vast experience and history in local coal seams provide confidence in coal quality; limited excursions can be managed with careful product segregation and blending. 2 5 10 Develop mine plan to provide readily available alternate mining locations to sustain expected production level; modify coal sales agreements to reflect coal quality. 2 3 6 22.2.8.2 Environmental Water quality and other permit requirements are subject to modification and such changes could have a material impact on the capability of the operator to meet modified standards or to receive new permits and modifications to existing permits. Permit protests may result in delays or denials to permit applications. Environmental standards and permit requirements have evolved significantly over the past 50 years and to-date, mining operators and regulatory bodies have been able to adapt successfully to evolving environmental requirements.

Comprehensive training and retraining programs, internal safety audits and examinations, regular mine inspections, safety meetings, along with support of trained fire brigades and mine rescue teams are among activities that greatly reduce accident risks. Employee health monitoring programs coupled with dust and noise monitoring and abatement reduce health risks to miners. As underground mines are developed and extended, observation of geological, hydrogeological and geotechnical conditions lead to modification of mine plans and procedures to enable safe work within the mine environments. Highlighted below are selected examples of safety and external factors relevant to Alpha’s operations. 22.2.8.5.1 Methane Management Coalbed methane is present in coal operations below drainage. Often the methane concentration in shallow coal seams is at such low levels that it can be readily managed with frequent testing and monitoring, vigilance and routine mine ventilation. Very high methane concentrations may be present

Excellent rock dust maintenance minimizes explosion propagation risk should an ignition occur. 2 5 10 Very high-level methane concentrations may require coal seam degasification and gob degasification where pillar extraction methods are employed. 2 3 6 22.2.8.5.2 Mine Fires Mine fires, once common at mine operations, are rare today. Most active coal miners have not encountered a mine fire. Vastly improved mine power and equipment electrical systems, along with safe mine practices reduce mine fire risks. Crew training and fire brigade support and training improve response for containment and control if a fire occurs. Spontaneous combustion within coal mines, which is the source of most fires that occur today, is not expected to commonly occur at the Alpha property. When spontaneous combustion conditions are present, monitoring systems are employed for early detection and mine plans are designed to facilitate isolation, containment and rapid extinguishment.

Injury or loss of life; potential loss of mine temporarily or permanently; damage to equipment and mine infrastructure. Inspection and maintenance of mine power, equipment and mine infrastructure; good housekeeping; frequent examination of conveyor belt entries; prompt removal of accumulations of combustible materials. 1 5 5 If spontaneous combustion conditions are present, enhanced monitoring and examination procedures will be implemented; mine design will incorporate features to facilitate isolation, containment and extinguishment of spontaneous combustion locations. 1 4 4 Alpha Metallurgical Resources, Inc.

Ground control-based risks can be mitigated through effective roof control plans which are supplemented with a strong understanding of future geotechnical conditions. Foremen and crews should be trained to examine the roof, rib and floor conditions and identify pending and immediate hazards. Multiple publicly available software programs can be used to assess pillar sizing and stability. Table 22-12: Ground Control (Risk 10) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Ground control issues cause roof failures, rib rolls, floor heave, etc. Injury or loss of life; catastrophic damage to equipment; production interruption. Regular inspection for change and signs of failure. Dynamic design of roof control plan and safety measures to honor observed conditions and exploration- based information; conservative pillar design. 4 3 12 Multiple operating sections to mitigate any lost production; availability of new working areas in case abandonment of section is required; availability of alternative roof control technologies in case of abrupt changes in mining conditions. 4 2 8 22.2.8.5.4 Availability of Supplies and Equipment The industry has periodically experienced difficulty receiving timely delivery of mine supplies and equipment. Availability issues often accompanied boom periods for coal demand. Any future delivery of supplies and equipment delays are expected to be temporary with limited impact on production. Table 22-13: Availability of Supplies and Equipment (Risk 11) Aspect Impact Control Measures Initial Risk Level Mitigation Measures Residual Risk Level P C R P C R Disruption of availability for supplies and equipment. Temporary interruption of production. Force majeure provision in coal sales agreements to limit liability for delayed or lost sales. 3 2 6 Work closely with customers to assure delayed coal delivery rather than cancelled sales; monitory external conditions and increase inventory of critical supplies; accelerate delivery of equipment when possible. 3 1 3 22.2.8.5.5 Labor Work stoppage due to labor protests are considered to be unlikely and accompanied by limited impact should it occur. Excellent employee relations and communications limit the exposure to outside protesters. Loss of supervisors and skilled employees to retirement is inevitable; the impact can be lessened with succession planning and training and training and mentorship of new employees.
