Notes to Financial Statements
Significant Accounting Policies [Text Block]	( 1 Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Hallador Energy Company (hereinafter known as, “we, us, or our”) and its wholly owned subsidiaries Sunrise Coal, LLC (Sunrise) and Hourglass Sands, LLC (Hourglass), and Sunrise’s wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Sunrise is engaged in the production of steam coal from mines located in western Indiana. Going Concern - Alleviation of Substantial Doubt In accordance with ASU 2014 15, Presentation of Financial Statements- Going Concern 205 40 one We performed the analysis, and our overall assessment was there were conditions or events, considered in the aggregate as of December 31, 2021, The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. During our analysis and overall assessment, it became clear that we were likely to violate one March 31, 2022 In March 2022, 5, Accordingly, the above factors have alleviated substantial doubt about the entity’s ability to continue as a going concern. Segment Information The Company’s significant operating segment includes the two Allowance for Doubtful Accounts The Company evaluates the need for an allowance for uncollectible receivables based on a review of account balances that are likely to be uncollectible, as determined by such variables as customer creditworthiness, the age of the receivables and disputed amounts. Historically, credit losses have been insignificant. At December 31, 2021 2020 no Inventory Inventory and parts and supplies are valued at the lower of average cost or net realizable value determined using the first first Prepaid expenses Prepaid expenses include prepaid insurance, prepaid maintenance expense, and a prepaid balance with our primary parts and supplies vendor. Advanced Royalties Coal leases that require minimum annual or advance payments and are recoverable from future production are generally deferred and charged to expense as the coal is subsequently produced. Advance royalties are included in other assets. Mining Properties Mining properties are recorded at cost. Interest costs applicable to major asset additions are capitalized during the construction period. Expenditures that extend the useful lives or increase the productivity of the assets are capitalized. The cost of maintenance and repairs that do not three twenty-five If facts and circumstances suggest that a long-lived asset may not 2 Mine Development Costs of developing new mines, including asset retirement obligation assets, or significantly expanding the capacity of existing mines, are capitalized and amortized using the units-of-production method over estimated recoverable reserves. Asset Retirement Obligations (ARO) – Reclamation At the time they are incurred, legal obligations associated with the retirement of long-lived assets are reflected at their estimated fair value, with a corresponding charge to mine development. Obligations are typically incurred when we commence development of underground and surface mines and include reclamation of support facilities, refuse areas and slurry ponds. Obligations are reflected at the present value of their future cash flows. We reflect accretion of the obligations for the period from the date they are incurred through the date they are extinguished. The ARO assets are amortized using the units-of-production method over estimated recoverable (proven and probable) reserves. We are using credit-adjusted risk-free discount rates ranging from 5.0% to 10% to discount the obligation, inflation rates anticipated during the time to reclamation, and cost estimates prepared by our engineers inclusive of market risk premiums. Federal and state laws require that mines be reclaimed in accordance with specific standards and approved reclamation plans, as outlined in mining permits. Activities include reclamation of pit and support acreage at surface mines, sealing portals at underground mines, and reclamation of refuse areas and slurry ponds. We review our ARO at least annually and reflect revisions for permit changes, changes in our estimated reclamation costs and changes in the estimated timing of such costs. The change in estimate was a result of a change in timing of expected reclamation of the Ace in the Hole Mine, Carlisle Mine, and Prosperity Mine and updates to inflation rates from when the liabilities were first not The table below (in thousands) reflects the changes to our ARO: Year Ended December 31, 2021 2020 Balance, beginning of year $ 16,277 $ 15,764 Accretion 1,504 1,381 Change in estimate (3,510 ) — Payments (146 ) (868 ) Balance, end of year 14,125 16,277 Less current portion (100 ) (100 ) Long-term balance, end of year $ 14,025 $ 16,177 Interest Rate Swaps The Company generally utilizes derivative instruments to manage exposures to interest rate risk on long-term debt. The Company enters into interest rate swaps in order to achieve a mix of fixed and variable rate debt that it deems appropriate. These interest rate swaps have not Statement of Cash Flows Cash equivalents include investments with maturities when purchased of three Income Taxes Income taxes are provided based on the liability method of accounting. The provision for income taxes is based on pretax financial income. Deferred tax assets and liabilities are recognized for the future expected tax consequences of temporary differences between income tax and financial reporting and principally relate to differences in the tax basis of assets and liabilities and their reported amounts, using enacted tax rates in effect for the year in which differences are expected to reverse. Net Income (Loss) per Share Basic net income (loss) per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period using the two two Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual amounts could differ from those estimates. The most significant estimates included in the preparation of the financial statements relate to: (i) deferred income tax accounts, (ii) coal reserves, (iii) depreciation, depletion, and amortization, (iv) estimates relating to interest rate swaps, (v) estimates used in our impairment analysis and measurement of impairments, and (vi) estimates used in the calculation of our asset retirement obligations.

Revenue from Contract with Customer [Text Block]	( 7 Revenue from Contracts with Customers We account for a contract with a customer when the parties have approved the contract and are committed to performing their respective obligations, the rights of each party are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. We recognize revenue when we satisfy a performance obligation by transferring control of a good or service to a customer. We utilize the normal purchase normal sales exception for all long-term sales contracts. Our revenue is derived from sales to customers of coal produced at our facilities. Our customers purchase coal directly from our mine sites and our Princeton Loop, where the sale occurs and where title, risk of loss, and control typically pass to the customer at that point. Our customers arrange for and bear the costs of transporting their coal from our mines to their plants or other specified discharge points. Our customers are typically domestic utility companies. Our coal sales agreements with our customers are fixed-priced, fixed-volume supply contracts, or include a predetermined escalation in price for each year. Price re-opener and index provisions may may Coal sales agreements will typically contain coal quality specifications. With coal quality specifications in place, the raw coal sold by us to the customer at the delivery point must be substantially free of magnetic material and other foreign material impurities and crushed to a maximum size as set forth in the respective coal sales agreement. Price adjustments are made and billed in the month the coal sale was recognized based on quality standards that are specified in the coal sales agreement, such as Btu factor, moisture, ash, and sulfur content and can result in either increases or decreases in the value of the coal shipped. Disaggregation of Revenue Revenue is disaggregated by primary geographic markets, as we believe this best depicts how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. 73% and 74% of our coal revenue for the years ended December 31, 2021 2020 Performance Obligations A performance obligation is a promise in a contract with a customer to provide distinct goods or services. Performance obligations are the unit of account for purposes of applying the revenue recognition standard and therefore determine when and how revenue is recognized. In most of our contracts, the customer contracts with us to provide coal that meets certain quality criteria. We consider each ton of coal a separate performance obligation and allocate the transaction price based on the base price per the contract, increased or decreased for quality adjustments. We recognize revenue at a point in time as the customer does not We have remaining performance obligations relating to fixed priced contracts of approximately $588 million, which represent the average fixed prices on our committed contracts as of December 31, 2021 2022 2023, We have remaining performance obligations relating to contracts with price reopeners of approximately $166 million, which represents our estimate of the expected re-opener price on committed contracts as of December 31, 2021 2024. The tons used to determine the remaining performance obligations are subject to adjustment in instances of force majeure and exercise of customer options to either take additional tons or reduce tonnage if such option exists in the customer contract.

Advance Royalties [Policy Text Block]	Advanced Royalties Coal leases that require minimum annual or advance payments and are recoverable from future production are generally deferred and charged to expense as the coal is subsequently produced. Advance royalties are included in other assets.

Mine Development [Policy Text Block]	Mine Development Costs of developing new mines, including asset retirement obligation assets, or significantly expanding the capacity of existing mines, are capitalized and amortized using the units-of-production method over estimated recoverable reserves.
Asset Retirement Obligation [Policy Text Block]	Asset Retirement Obligations (ARO) – Reclamation At the time they are incurred, legal obligations associated with the retirement of long-lived assets are reflected at their estimated fair value, with a corresponding charge to mine development. Obligations are typically incurred when we commence development of underground and surface mines and include reclamation of support facilities, refuse areas and slurry ponds. Obligations are reflected at the present value of their future cash flows. We reflect accretion of the obligations for the period from the date they are incurred through the date they are extinguished. The ARO assets are amortized using the units-of-production method over estimated recoverable (proven and probable) reserves. We are using credit-adjusted risk-free discount rates ranging from 5.0% to 10% to discount the obligation, inflation rates anticipated during the time to reclamation, and cost estimates prepared by our engineers inclusive of market risk premiums. Federal and state laws require that mines be reclaimed in accordance with specific standards and approved reclamation plans, as outlined in mining permits. Activities include reclamation of pit and support acreage at surface mines, sealing portals at underground mines, and reclamation of refuse areas and slurry ponds. We review our ARO at least annually and reflect revisions for permit changes, changes in our estimated reclamation costs and changes in the estimated timing of such costs. The change in estimate was a result of a change in timing of expected reclamation of the Ace in the Hole Mine, Carlisle Mine, and Prosperity Mine and updates to inflation rates from when the liabilities were first not The table below (in thousands) reflects the changes to our ARO: Year Ended December 31, 2021 2020 Balance, beginning of year $ 16,277 $ 15,764 Accretion 1,504 1,381 Change in estimate (3,510 ) — Payments (146 ) (868 ) Balance, end of year 14,125 16,277 Less current portion (100 ) (100 ) Long-term balance, end of year $ 14,025 $ 16,177

Income Tax, Policy [Policy Text Block]	Income Taxes Income taxes are provided based on the liability method of accounting. The provision for income taxes is based on pretax financial income. Deferred tax assets and liabilities are recognized for the future expected tax consequences of temporary differences between income tax and financial reporting and principally relate to differences in the tax basis of assets and liabilities and their reported amounts, using enacted tax rates in effect for the year in which differences are expected to reverse.
