• SS-2H ST1 well achieved Beetaloo Basin record average 60-day initial production (IP60) flow rate of 6.8 MMcf/d
• Exit rate maintains steady, low-declining curve at 6.4 MMcf/d with flowing wellhead pressure of ~720 psi
• Normalized rate of 12.4 MMcf/d over 10,000-foot horizontal aligns with average of over 11,000 Marcellus Shale wells

Tamboran Resources' Shenandoah South 2H sidetrack (SS-2H ST1) well achieved a Beetaloo Basin record average 60-day initial production (IP60) flow rate of 6.8 million cubic feet per day (MMcf/d) over a 5,483-foot stimulated horizontal within the Mid Velkerri B Shale. The exit rate maintains a steady, low-declining curve at 6.4 MMcf/d with a flowing wellhead pressure of ~720 psi and has exhibited less decline than the previous SS-1H well over the last 30 days of testing. The average flow rate of 12.4 MMcf/d over a normalized 10,000-foot horizontal section remains in-line with an average of more than 11,000 wells in the Marcellus Shale dry gas area with production for over a 12-month period. The result reinforces Tamboran's view of commercial deliverability from the Beetaloo Basin to the Australian domestic East Coast gas market. Tamboran has commenced the three-well 2025 Shenandoah South Pilot Project drilling program with the spudding of the Shenandoah South 4H (SS-4H) well.

Tamboran's contract with the Northern Territory Government is expected to play a major role in delivering 40 MMcf/d of energy security for all Territorians.

Tamboran has commenced the largest planned drilling program in the Beetaloo Basin to date, with three wells to be drilled back-to-back with a total combined horizontal section of 30,000 feet. These three wells are the last remaining wells required to be drilled as part of Tamboran's commitment to deliver 40 MMcf/d to the local market under its gas sales contract with the Northern Territory Government.
