• Tamboran delivered record Beetaloo Basin IP30, 60 and 90 flow testing
• Commenced the largest drilling program in the Beetaloo Basin to date
• Secured Native Title Holder and NTG approval to sell appraisal gas

Tamboran Resources Corporation reported strong operational results in its fourth quarter activities report for the period ended June 30, 2025. The company delivered record Beetaloo Basin IP30, 60 and 90 flow testing from the Shenandoah South 2H sidetrack well, with flow rates increasing by around 2% over the last 30 days without any downhole intervention. Tamboran also commenced the largest drilling program in the Beetaloo Basin, including three batch-drilled wells with 10,000-foot horizontal sections. The company reached a key milestone in securing Native Title Holder and Northern Territory Government approval to sell appraisal gas under the Beneficial Use of Gas legislation. Tamboran engaged in a formal farmout process for its ~400,000-acre Phase 2 Development Area and made changes to its board and management, appointing Dick Stoneburner as interim CEO. The company ended the quarter with a strong cash balance of US$45.2 million and no debt.

Tamboran expects the five wells from its current drilling program to deliver the contracted 40 MMcf/d volume required under the Gas Sales Agreement with the Northern Territory Government, with gas sales expected to commence in mid-2026.

Tamboran plans to stimulate the full 10,000-foot horizontal section of the SS-4H well in early 2026 and expects to stimulate the remaining three drilled and uncompleted wells (SS-3H, -4H and -5H) in 2Q 2026 ahead of the commencement of gas sales.
