MANAGING DIRECTOR’S REPORT Bass is pleased to present the first half financial results for the 2023 fiscal year. This year, 2023, will be the first year the company has reported its results following the acquisition of its Cooper Basin properties. The Company now has two independent cash generating units, one in Indonesia and of course the Cooper Basin unit here in Australia. Bass has a commitment to provide a safe workplace for its employees and to work harmoniously within the communities in which we operate. I am proud to say that we have recorded over 6-million-man hours without a Lost Time Injury. The Company delivered an EBITDA of $403k down 31% over the previous half year. This result was driven by the accelerated cost recovery for the drilling of Tangai 5 in the previous half year. The NLAT was ($120k) although Bass is expecting to report a NPAT for the full year, this being the first full year of full contributions from the two business units. Bass is committed to maximising the potential of the Company’s assets and has already been able to double production from the Cooper Basin assets since they were acquired. Recent debottlenecking activities in Indonesia has also seen a significant increase in production. Free cash flow generated from these producing assets allows financial flexibility for Bass to pursue its growth strategy. The focus for 2023 and beyond is to grow Bass into a mid-tier oil and gas producer by advancing growth initiatives across its Indonesian and Australian portfolio. Whilst Bass is an oil producer in both Australia and Indonesia, the Company has outlined plans that will see Bass join the ranks of Australian gas producers supplying the East Coast gas market with a successful Extended Production Test at the Kiwi 1 well, currently planned to commence before year end. This is independent of a significant potential ‘company making’ opportunity identified last year that lies in the deep Permian coal gas play in Bass' 100% owned PEL 182. Half Year Summary Sales revenue increased as a result of higher production despite a lower realised oil price in this first half year. The results are summarised below. With no debt and sufficient cash reserves, Bass is wellpositioned to execute its strategy and continue its growth trajectory in 2023. (All amounts are in United States dollars unless otherwise stated) • 25% increase in production to 57,000 barrels (1H CY22 46,000 barrels) including production from the Cooper Basin assets • 13% increase in 1H CY23 sales revenue to $2.88 million (1H CY22 $2.54 million) from higher production • Cash position $1.52 million as at 30 June 2023 • A NPAT of -$0.12 million (1H CY22 approximately $0.16 million) Bass Oil Limited Half Year Report June 2023 3 MANAGING DIRECTOR’S REPORT (cont’d) Financial and Operating Performance Key Performance Metrics 1H CY23 1H CY22 Change Net Production3 (mbbl) 57.37 46.02 24.7% Net Oil Sales3 (mbbl) 52.77 44.69 18.1% Net Entitlement Oil3 (mbbl) 37.11 23.18 60.1% Sales Revenue (US$million) 2.88 2.54 13.4% Cash (US$million) 1.52 1.78 -14.6% Average Realised Oil Price (USD) 77.13 104.45 -26.2% EBITDA1 (US$,000) 403 584 -31.2% NPAT/NLAT2 (US$,000) -120 159 na 1 .

Half-yearly oil sales were 52,769 barrels of oil net to Bass. The net entitlement oil to Bass was 37,109 barrels for the half-year after Domestic Market Obligation (DMO), up 60%. The Company realised a 13% increase in sales revenue driven by the uplift in production. 1H CY22 vs 1H CY23 Production (kbbl) 15 12 9 6 3 0 January February March CY22 April May June CY23 Figure 1: Bass Monthly Production Bass Oil Limited Half Year Report June 2023 4 MANAGING DIRECTOR’S REPORT (cont’d) Liquidity / Cash Position: At 30 June 2023, Bass cash reserves had increased to $1.52 million from $1.48 million at 31 December 2022. The Company is not carrying any debt and holds US$1.54 million on deposit to support a rehabilitation bond in favor of the South Australian Department for Energy and Mining. Development Planning: Oil Optimisation Since completion of the acquisition of the Cooper Basin assets, the Company has successfully completed a program of optimisation initiatives to increase production, including the workover of the Worrior 11 well. As a result, production from the fields at the end of this half year had increased from 65 bopd to circa 120 bopd. The Company is also adding artificial lift capacity at the Worrior field by installing a second pumping unit. The installation of the second unit will provide additional artificial lift capacity to for wells not currently on pump and provide a backup in the event of the failure of the existing single unit. Gas Development The Kiwi gas development feasibility study has been progressing well. Bass considers there is potential for the existence of a significant stratigraphic upside to the 2003 Kiwi gas discovery. A mapping project aimed at quantifying the stratigraphic upside gas trapping potential, utilising the most recent 3D seismic acquired over the area, is almost complete. Concurrently, Bass is planning to complete the Kiwi 1 well as soon as possible and perform an extended production test in order to confirm the gas composition and potential field size. This work is considered a precursor and enabler to the commercialisation of the deep coal gas resource potential in the Company’s 100% owned PEL 182 licence. See Figure 1. Indonesian Oil After the end of the half year, the Bass announced it had been granted a 10-year extension to the 55% owned and operated Tangai-Sukananti KSO. The license will now expire in September 2035. The extension of the KSO will be of significant benefit to Bass. The increase in tenure will result in a material increase in reserves and is forecast to increase free cash flow from the Indonesian business due to the improved fiscal terms. The extension will also allow the Indonesian based team additional time to take advantage of the upside becoming evident in the Bunian and Tangai fields. An example of the potential upside was the recent 35% increase in oil production after a flowline debottlenecking project was completed. The team in Indonesia have started planning for a future drilling program which will include the Bunian 6 development well, targeting the undrained oil in the southwest of the Bunian field and a potential extension of the Bunian field to Bunian West. The potential for an additional development well in the Tangai field will also be evaluated following the success of Tangai 5. See Figure 2. Bass Oil Limited Half Year Report June 2023 5 MANAGING DIRECTOR’S REPORT (cont’d) Figure 1: Cooper Basin assets Figure 2: Tangai-Sukananti KSO Location Map Business Development: Bass is actively seeking opportunities to expand its operations and grow production. In addition to organic growth contained within Bass’ existing portfolio the Company is focused on acquiring assets with low-risk growth potential that have the are able to deliver above average returns by leveraging its expertise and resources.

Bass Oil Limited Half Year Report June 2023 13 NOTES TO THE FINANCIAL STATEMENTS For the half year ended 30 June 2023 Note 1. Corporate Information The consolidated financial statements of Bass Oil Limited (“Parent Entity” or “Company”) and its controlled entities (collectively as “Consolidated Entity” or “the Group”) for the half-year ended 30 June 2023 was authorised for issue in accordance with a resolution of the directors on 8 September 2023. Bass Oil Limited is a company limited by shares incorporated in Australia whose shares are publicly traded on the Australian Stock Exchange. The nature of the operations and principal activities of the Group are oil production. Note 2. Summary of Significant Accounting Policies Basis of Preparation The consolidated financial statements have been prepared on the basis of historical cost. Cost is based on the fair values of the consideration given in exchange for assets. All amounts are presented in United States dollars, unless otherwise noted. The accounting policies and methods of computation adopted in the preparation of the half-year financial report are consistent with those adopted and disclosed in the Company’s 2022 annual financial report for the financial year ended 31 December 2022. These accounting policies are consistent with Australian Accounting Standards and with International Financial Reporting Standards. In the application of the Group’s accounting policies, which are described below, management is required to make judgements, estimates and assumptions about carrying values of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgements. Actual results may differ from these estimates. There has been a change in accounting policies in how the Group recognises the useful life of oil assets for the Cooper Basin oil properties in the calculation of amortisation. There has also been a change in that the Group is now recognising exploration and evaluation assets. Except where indicated otherwise, all amounts are presented in United States dollars. Going Concern The consolidated financial statements have been prepared on the going concern basis, which assumes that the Group will be able to realise its assets and extinguish its liabilities in the normal course of business and at amounts stated in the financial report. For the financial half-year ended 30 June 2023 the Group earned a loss after tax of $119,799 (30 June 2022: profit of $158,993), had a net cash inflow from operating activities of $560,167 (30 June 2022: outflow $290,083), a net cash outflow from investing activities of $479,408 (30 June 2022: $606,233) and had a net cash outflow from financing activities of $20,636 (30 June 2022: inflow $1,180,622). The Directors have prepared a cash flow forecast through to September 2024 which indicates that the Group has sufficient funds to remit the second instalment of the performance bond for the rehabilitation of the Cooper Basin properties in favour of the SA Department for Energy and Mining and invest in further projects to maintain/increase production levels. Bass Oil Limited Half Year Report June 2023 14 NOTES TO THE FINANCIAL STATEMENTS For the half year ended 30 June 2023 Note 2. Summary of Significant Accounting Policies (cont’d) Going concern (cont’d) The Group may be required to secure additional funding (which may be sourced as debt or equity) in the event of unforeseen issues arising including but not limited to a weakness in the price of oil, field production performance or projected cash returns from the Company’s Indonesian subsidiary or to fund drilling and non-drilling projects beyond September 2024. Based on the Group’s cash flow forecast, achieving the funding referred to above and achieving successful results from drilling and non-drilling projects, the Directors believe that the Group will be able to continue as a going concern. Should the Group be unsuccessful in achieving the projected levels of cashflow from initiatives set out above, a material uncertainty would exist that may cast significant doubt on the ability of the Group to continue as a going concern and, therefore, whether it will realise its assets and extinguish its liabilities in the normal course of business. The financial report does not include any adjustments relating to the recoverability and classification of recorded asset amounts and the amount and classification of liabilities that might be necessary should the Group not continue as a going concern. (a) Statement of Compliance These financial statements are general purpose financial statements which have been prepared in accordance with the Corporations Act 2001, Accounting Standards and Interpretations, and comply with other requirements of the law. The financial statements comprise the consolidated statements of the Group. For the purpose of preparing the consolidated financial statements, the Company is a forprofit entity. Compliance with Australian Accounting Standards ensures that the financial statements and notes of the Company and the Group comply with International Financial Reporting Standards. (b) New Accounting Standards and Interpretations The Group has adopted all the new and revised Standards and Interpretations issued by the Australian Accounting Standards Board (the AASB) that are relevant to its operations and effective for an accounting period that begins on or after 1 January 2023. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted and will not have a material impact on the financial statements. (c) Critical accounting estimates and judgements The preparation of a financial report in conformity with Australian Accounting Standards requires management to make judgements, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgements about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Bass Oil Limited Half Year Report June 2023 15 NOTES TO THE FINANCIAL STATEMENTS For the half year ended 30 June 2023 Note 2. (c) Summary of Significant Accounting Policies (cont’d) Critical accounting estimates and judgements (cont’d) These accounting policies have been consistently applied by each entity with the exception of oil property assets, in the consolidated entity, and the estimates and underlying assumptions are reviewed on an ongoing basis. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying values of assets and liabilities within the next financial year are discussed below. (i) Impairment of Oil Property Assets Oil properties impairment testing requires an estimation of the value in use of the cash generating unit to which deferred costs have been allocated when impairment indicators have been identified. The value in use calculation requires the entity to estimate the future cash flows expected to arise from the cash generating unit and a suitable discount rate in order to calculate present value. Other assumptions used in the calculations which could have an impact on future years includes available reserves and oil prices. (ii) Useful Life of Oil Property Assets Oil properties are amortised on the Units of Production basis using the latest approved estimate of Proven (1P) Reserves. Amortisation is charged only once production has commenced. No amortisation is charged on areas under development where production has not yet commenced. Estimates of reserve quantities are a critical estimate impacting amortisation of oil property assets. On 1 January 2023 there was a change in accounting policy for the Australian production assets. The Australian production assets are now amortised on Proven and Probable (2P) reserves. The reason for the change is based on the Groups estimate of the forecast life of the field. The oil property assets in the Cooper Basin are late life fields and they were acquired with significant historical production data. The change reduces the amount of amortisation from $346,597 (1P) to $169,988 (2P). There is no change for the Indonesian oil properties. (iii) Estimates of Reserve Quantities The estimated quantities of Proven and Probable hydrocarbon reserves reported by the Company are integral to the calculation of the amortisation expense relating to oil properties, and to the assessment of possible impairment of these assets. Estimated reserve quantities are based upon interpretations of geological and geophysical models and assessments of the technical feasibility and commercial viability of producing the reserves. These assessments require assumptions to be made regarding future development and production costs, commodity prices, exchange rates and fiscal regimes. The estimates of reserves may change from period to period as the economic assumptions used to estimate the reserves can change from period to period, and as additional geological data is generated during the course of operations. Reserves estimates are prepared in accordance with the Company’s policies and procedures for reserves estim
