ASX Announcement 3 August 2023 Buru confirms Rafael resource development strategy Highlights • Buru confirms phased development strategy to commercialise its 100% owned and operated Rafael discovery – the first proven significant conventional gas and condensate field in the Canning Basin of Western Australia. • This strategy follows completion of concept studies in collaboration with Petrofac Limited, Transborders Energy and Technip Energies1 for development concepts that cover the full range of independently assessed contingent resources of gas and condensate 2. • Phased development generates early cashflows with staged capital expenditure, delivering accelerated benefits to shareholders and the Kimberley, and optimises larger scale development based on Rafael resource appraisal outcomes. • Imminent commencement of high value Rafael 3D seismic survey, with resource appraisal drilling planned for 2024. • Commercially attractive stand-alone Phase 1 ‘reference case’ development includes small footprint, scalable, Kimberley based hybrid gas to power and renewables project based on the already defined low volume estimate of the Rafael contingent resource. Development work underway to progress to Front End Engineering Design (FEED), targeting production in 2027. • Phase 2 to follow rapidly, informed by appraisal drilling in 2024 with concept selection targeted by mid-2025 and commencement of FEED shortly thereafter. Concept studies completed demonstrating commercial attractiveness for methanol (reference case), ammonia, and LNG projects, complemented with Carbon Capture and Storage through Buru’s Geovault subsidiary, based on mid to high volume estimates of Rafael contingent resources. • Disciplined strategy designed to support parallel partner selection process for the Rafael development, targeting both Australian and international potential partners. • Buru continues to build on its capability as a successful developer and producer to deliver its first conventional gas and condensate project in the Canning Basin to fruition for the benefit of its shareholders, the Traditional Owners, the Western Australian Government, and the communities in the Kimberley. 1.

Buru Energy (Buru, Company) is pleased to provide investors with an update on the commercialisation of its Rafael conventional gas and condensate discovery, in the Canning Basin of northwest Western Australia. 1 Level 2, 16 Ord St West Perth WA 6005 1800 337 330 info@buruenergy.com ABN 71 130 651 437 Commenting on the release, Buru’s CEO Thomas Nador said: “With full ownership of the Rafael discovery, Buru continues to de-risk the development through a project realisation approach that is designed to balance certainty of development outcome and value with the ongoing maturity of understanding of the Rafael accumulation. The work done to date confirms that Rafael gas and condensate can be technically, commercially, and economically developed across the full range of independently assessed contingent resources, with a sequenced development based on appraisal outcomes providing strategic advantages to resource development. This strategy will support the potential transformation of the Kimberley power system by providing a mix of low carbon intensity, secure and affordable energy to regional industrial consumers and communities in the near term, and also help optimise a full-scale, CCS supported, and export focussed development in the medium to longer term. With Buru’s high appraisal value 3D seismic program due to commence within days, planning for appraisal drilling next year well advanced, and for the first time, a clear line of sight to the Rafael development via a staged, risk balanced commercialisation plan – Buru has the ingredients to generate significant value and benefits to stakeholders, and prospective development partners.” Background The Rafael 1 discovery well was drilled in 2021 and defined a significant gas and condensate resource in the Ungani Dolomite equivalent reservoir with additional potential in the dolomitised Upper Laurel Carbonate reservoir. A successful flow test of the Rafael 1 well in March 2022 confirmed the Ungani Dolomite conventional reservoir contained high quality gas with low reservoir CO2, and a high condensate content of 40 barrels per million cubic feet of gas. Following an independent contingent resource assessment in April 2022, a Discovery Assessment Report was submitted to the Government in May 2022. A Declaration of Location application for the Rafael discovery was submitted to Government in April 2023, which was subsequently approved in July 2023, triggering the four-year period during which Buru may apply for either a Production Licence or a Retention Lease. A 3D seismic survey over the Rafael structure will be acquired, data processed, and fast track interpreted over the coming months to provide confirmation of Rafael structural size, confirm potential gas column extent, and inform appraisal well location selection for a targeted 2024 appraisal drilling campaign. The opportunity for Rafael gas and condensate commercialisation is compelling. As a strategically sized and located, high quality, low CO2 conventional gas accumulation, the development of this resource has the potential to transform Buru to a major upstream energy provider in Western Australia. Buru’s commanding acreage position in the Canning Basin, and the potential of the basin for Carbon Capture and Storage being developed through Buru’s Geovault subsidiary enables the pursuit of a fast tracked development. 2 Level 2, 16 Ord St West Perth WA 6005 1800 337 330 info@buruenergy.com ABN 71 130 651 437 Rafael development strategy Building on its extensive previous knowledge and work on development concepts in the Basin, Buru has been rigorously evaluating a range of options to commercialise its Rafael gas and condensate discovery. The first of these studies, completed in collaboration with Transborders Energy and Technip Energies in April 2023, was focused on the high case Rafael resource volume scenario and demonstrated that a Kimberley based Floating LNG (FLNG) facility is a technically, commercially, and economically feasible option to develop Rafael as an export project if appraisal outcomes confirm the resource volumes required. Refer to ASX Release of 18 April 2023 relating to the details of this study. The other studies set out in this report have been conducted in parallel with this FLNG study by Buru with Petrofac Limited (Petrofac). Petrofac is an international energy services company that designs, builds, manages, and maintains oil, gas, refining, petrochemical and renewable energy infrastructure. These studies confirmed that Rafael may be developed technically, commercially, and economically across lower Rafael resource volume scenarios, including on the lowest independently assessed contingent resource volume case which is the already discovered resource in the Rafael 1 well. The insight from the first stage of the evaluation that the immediate discovered resource is sufficient for a first phase development has led Buru to formulate a development strategy to commercialise the Rafael resource in phases driven by appraisal resource volumes. This phased approach will deliver a robust first phase development, accelerate positive cashflows, reduce initial capital intensity and ensure an optimised second phase development will exploit a fully delineated Rafael resource. Concept study outcomes Table 1 describes the various development concepts that have passed technical, commercial, and economic feasibility hurdles across a range of Rafael contingent resource volume scenarios. Concept 1 Development Phase Phase 1 Rafael Resource threshold Less than 59bcf Project 2 Phase 2 400bcf & 800bcf Phase 1 plus blue methanol production for export or regional marine fuel bunkering with potential for blue ammonia production. Phase 1 plus blue ammonia production for export. 2a Phase 2 400bcf & 800bcf 2b Phase 2 Greater than 1 TCF Kimberley Power with Condensate Export Phase 1 plus LNG production for export. Table 1 – Concept Studies confirm development feasibility 3 Level 2, 16 Ord St West Perth WA 6005 1800 337 330 info@buruenergy.com ABN 71 130 651 437 Note: A case to develop Rafael via infrastructure located at the North West Shelf processing precinct was not part of this screening process at this time due to the uncertainty in the nature and timing associated with approvals and the cost escalation for the pipeline infrastructure needed to transport the gas from the Rafael field to Karratha for liquefaction since the completion of Buru’s previous studies on the Great Northern Pipeline. The resource thresholds for the Development Phases fall within the independently assessed resource volumes in the ERCE Contingent Resources assessment as set out in Buru ASX release of 26 April 2022. These volumes were probabilistically derived and not based on a physical realisation. Buru has undertaken an internal deterministic assessment of resource volumes based on additional mapping and review of well data since the ERCE evaluation and as would be expected, these fall within the probabilistic volume ranges. Buru’s view based on these internal evaluations is that the Phase 2 Development phases are supported by mid case deterministic volumes. Based on the above, Buru is now progressing technical and commercial concept maturation for a Phase 1 project, whilst preparing for rapid concept selection and FEED entry for a Phase 2 project following resource appraisal in 2024. More information on the concepts is provided as Attachment 1. Opportunity delivery plan Phasing the development will deliver numerous benefits including early cashflows to Buru and reduced capital expenditure to reach first production. Phasing the development will also facilitate a wider range of project financing options (including access to government grants and incentives), and an overall improved funding position for Buru. Figure 1 below describes the high-level activities for a sequenced development of the Rafael resource.
