Tamboran Resources Corporation ARBN 672 879 024 Tower One, International Towers Suite 1, Level 39, 100 Barangaroo Avenue, Barangaroo NSW 2000, Australia +61 2 8330 6626 www.tamboran.com First quarter activities report for period ended December 31, 2024 Highlights • During the December quarter, Tamboran successfully drilled, cased and cemented the Shenandoah South 2H sidetrack (SS-2H ST1) and 3H (SS-3H) wells in EP 98 to total measured depths of 16,182 feet (4,932 metres) and 21,169 feet (6,452 metres) respectively. The SS-3H well included the first 10,000-foot (3,048-metre) horizontal section in the Mid Velkerri B Shale. • Stimulation activities with Liberty Energy’s (NYSE: LBRT) 80,000 hydraulic horsepower (HHP) modern stimulation equipment, commenced in January 2025. The SS-2H ST1 well completed 35 stages across a 5,483-foot (1,671-metre) horizontal section. • The Company took precautionary steps to pause SS-3H completion operations due to detection of stress in the casing connection. Reinforcement activities are planned to be conducted in 1Q 2025, with re-commencement of the stimulation program in 2Q 2025 ahead of IP30 in mid-2025. • Tamboran entered into binding agreements with APA Group (ASX: APA) whereby APA will build, own and operate the 23-mile (37 kilometre) 12-inch diameter Sturt Plateau Pipeline (SPP) for the proposed Shenandoah South (SS) Pilot Project. Long lead items (LLIs) have been secured. • During the quarter, Tamboran secured a committed US$23 million (A$35 million) line of credit from Macquarie Bank Limited (Macquarie), part of which will be used for guarantees required by APA for the construction of the SPP. • In January 2025, Tamboran entered into a non-binding MOU with Santos Limited (ASX: STO) to undertake technical studies relating to a potential Darwin LNG (DLNG) Train 2 expansion and collaborative work on the jointly owned EP 161 acreage in the Beetaloo Basin. • As at December 31, 2024, the Company had a cash balance of US$59.4 million, following the receipt of A$9.9 million (US$6.2 million) research and development (R&D) tax credit relating to the Company’s FY23 Beetaloo Basin activities. Tamboran Resources Corporation’s Chief Executive Officer, Joel Riddle said: “During the December quarter, we maintained our momentum towards first gas production in the Beetaloo Basin having completed the drilling of the first two production wells at SS-2H ST1 and SS-3H. Lessons from the original SS-2H well were incorporated into drilling of these two wells, resulting in a material step change in drilling efficiency. The SS-3H well was drilled in 25 days, 10 days and 43% faster than the SS- 2H well. ANNOUNCEMENT February 13, 2025 Tamboran Resources Corporation (NYSE: TBN; ASX: TBN)
2 “We reached binding agreements with APA to progress with pipeline infrastructure to deliver sales gas from the proposed Shenandoah South Pilot Project into the Northern Territory gas network. APA will build, own and operate the pipeline. Tamboran and Daly Waters Energy (DWE) have contracted all foundation capacity on the SPP from the commencement of operations until at least 2041. Key Government approvals for the construction of the Sturt Plateau Compression Facility (SPCF) have also been secured. “In January 2025, we commenced the stimulation of the SS-2H ST1 and SS-3H wells. A total of 35 stages were completed in the SS-2H ST1 well over a 5,483-foot (1,671-metre) horizontal section in the Mid Velkerri B Shale. The operations achieved Beetaloo Basin record average proppant intensity of 2,706 pounds per foot (lb/ft), which was ~26% higher than the SS-1H well. The SS-2H ST1 well is currently being cleaned ahead of the commencement of flow testing, with IP30 flow rates anticipated in April 2025. “These initial two wells for the Pilot project are crucial for Tamboran to deliver much-needed gas volumes into the Northern Territory market. With the majority of its electricity generated from natural gas, the Northern Territory will benefit significantly from this new source of supply. “Importantly, the project will generate revenue through royalties for Native Title Holders and the Northern Territory Government, while also creating employment opportunities for Traditional Owners. “Australia must embrace responsible domestic gas production, particularly from regions like the Beetaloo Basin. The Beetaloo is subject to stringent regulations to ensure high environmental and emissions standards. Local sources of natural gas offer a compelling advantage over reliance on international imports, which may originate from less regulated environments with potentially higher emissions and costs.” EP 76, 98 and 117 Tamboran 38.75 per cent working interest (47.5 per cent working interest in 46,080 acres) and operator During the quarter, Tamboran completed drilling operations at the SS-2H ST1 and SS-3H wells with the Helmerich & Payne (NYSE: HP) FlexRig® super-spec rig in Beetaloo Basin exploration permit EP 98. In November 2024, the SS-2H ST1 well was drilled, cased and cemented to a measured depth of 16,182 feet (4,932 metres). The well includes a 5,906-foot (1,800-metre) horizontal section within the Mid Velkerri B Shale of which ~5,483 feet (~1,671 metres) was stimulated. In December 2024, the SS-3H well was successfully drilled, cased and cemented to a measured depth of 21,169 feet (6,452 metres), including a 10,000-foot (3,048-metre) horizontal section within the Mid Velkerri B Shale. Drilling operations at SS-3H took a total of 25 days (spud to TD) and achieved an average drilling rate of 843 feet per day, 10 days and 43% faster than the SS-2H well, the only well previously drilled to total depth of more than 20,000 feet. Data from both wells has demonstrated strong gas shows and a continuation of the high-quality shale and rock properties observed in the Shenandoah region, including a gentle, undulating structure with no faulting observed along the ~10,000-foot section.
3 Following the end of the quarter, the stimulation campaign commenced across both wells. The SS-2H ST1 well completed stimulation activities over 35 stages across a 5,483-foot (1,671-metre) horizontal section, delivering average proppant intensity of 2,706 lb/ft. This exceeded all previous completion activities in the Beetaloo Basin to date and achieved wellhead injection rates above 100 barrels per minute (bpm). The SS-2H ST1 well will be completed ahead of clean out activities and the commencement of initial flow back and extended production testing. The IP30 flow rates are expected to be released in April 2025. At the SS-3H well, the Company took proactive and precautionary steps to pause completion operations due to the detection of stress in the casing connection. Reinforcement activities are planned to be conducted in 1Q 2025 with stimulation activities planned to recommence in 2Q 2025. The deferred stimulation program provides an opportunity to incorporate lessons from the SS-2H ST1 campaign to increase efficiency and place higher portion of proppant under the optimized Tamboran v2 design. The IP30 flow rates are expected to be released in mid-2025. EP 161 Santos 75 per cent working interest and operator, Tamboran 25 per cent working interest During the quarter, the operator completed the 2D seismic program over the Jibera South and Newcastle South areas. Processing of seismic lines across ~200 kilometres has commenced, and results are expected in 2Q 2025. Ecology and archaeology surveys were also completed over the two areas. EP 136, EP 143 and EP(A) 197 Tamboran 100 per cent working interest and operator During the quarter, The Northern Territory Government approved Tamboran's EP 143 variation of work program for Term 2. Under the variation Tamboran are required to acquire 2D seismic and drill a stratigraphic well in 2025/26 and 2027/28, respectively. No activity was undertaken on the EP 136 acreage during the period. Commercial and Corporate Binding agreements with APA to deliver the Sturt Plateau Pipeline Tamboran entered into binding agreements with APA Group whereby APA will build, own and operate the 23-mile (37 kilometre) 12-inch diameter SPP for the proposed SS Pilot Project. The SPP will connect the SPCF to the existing APA-owned Amadeus Gas Pipeline (AGP), the delivery point for gas volumes under the Gas Sales Agreement (GSA) with the Northern Territory Government.
4 Tamboran and DWE have contracted all foundation capacity on the SPP from the commencement of operations until at least 2041, which reflects the term of the GSA and have competitive access and pricing rights to contract capacity following completion of the initial term. Long-lead items have been ordered, detailed design is nearing completion, and the approvals process continues to progress. The project remains on schedule to deliver gas into the Northern Territory by 1H 2026, subject to weather and final stakeholder approvals. Sturt Plateau Compression Project update In January 2025, Tamboran awarded Enscope, an Australian engineering consultancy company an Engineering, Procurement, Construction and Management contract to construct the SPCF, which is located adjacent to the SS2 well pad. Tamboran has 50% interest in the SPCF with Daly Waters infrastructure, LP holding the remaining 50% interest. The facility is expected to process gas from the Shenandoah South wells for delivery into the ~40 MMcf/d GSA with the Northern Territory Government. Permitting, design, and procurement processes for the project are on schedule, and the project remains on track to be operational in 1H 2026 to deliver first gas production under the GSA with the Northern Territory Government. Construction activities are expected to commence in the 2025 dry season. Committed Line of Credit with Macquarie Bank Tamboran secured a committed ~US$23 million (A$35 million) line of credit from Macquarie. The line of credit will be used to provide environmental and decommissioning bonds to the Northern Territory Government and bank guarantees for strategic infrastructure partners, including guarantees required by APA Group for the construction of the SPP. The line of credit is included in the Commitments and Contingencies note in the financial statements and includes several financial covenants that the Company must comply with. At December 31, 2024, Tamboran had drawn ~US$4.0 million (A$6.4 million) of credit to provide to APA Group for construction of the SPP. Non-binding MOU signed with Santos to progress studies for Darwin LNG expansion In January 2025, Tamboran announced the Company had entered a non-binding Memorandum of Understanding (MOU) to undertake technical studies relating to a potential Darwin LNG (DLNG) Train 2 expansion and collaborative work on Beetaloo Basin midstream infrastructure.
5 The goal of the studies is to evaluate options for supplying natural gas to a potential 6 MTPA expansion train at the existing DLNG facility at Middle Arm. Tamboran will run this process in parallel with development activity for the greenfield NTLNG project, with potential for DLNG2 to be the first new LNG train followed by up to 4 trains at NTLNG. Sale of US drilling rig During the quarter, Tamboran received the remaining US$8.1 million (pre-fees) payment for the sale of the US drilling rig located in the US. The rig was originally acquired for import into Australia prior to Tamboran’s partnership with H&P. Tamboran completes Methane Satellite Monitoring Campaign Tamboran has completed a 10-month Methane Satellite Monitoring Campaign across the Company’s assets in the Northern Territory. This was the first ever methane satellite monitoring campaign of hydrocarbon assets in the Northern Territory. Since March 2024, 12 methane satellites operated by GHGSat monitored Tamboran’s Beetaloo Basin assets. Across 78 satellite observations no methane emissions were recorded from Tamboran assets. This is an example of Tamboran going “beyond compliance” and using new and innovative technology to protect the environment and help achieve its aspirations of Net Zero equity Scope 1 and 2 GHG emissions from the commencement of commercial production.
