Commenced Spudding Of Third Well TE-B06003

NuEnergy Gas Limited (“NuEnergy” or “the Company”) (ASX: NGY) is pleased to announce the commencement of drilling operations for the TE-B06003 well at its Tanjung Enim Production Sharing Contract (“PSC”) Plan of Development 1 (“Tanjung Enim POD1”) contract area. The TE-B06003 well is the third of four planned CBM wells under NuEnergy’s Early Gas Sales Initiative, which targets initial gas sales of 1 million standard cubic feet per day (“mmscfd”). This milestone follows the successful completion of the first and the second wells.

A hydraulic drilling rig was rigged down to the recently completed TE-B06002 well on 19 July 2025 and mobilized and rigged up at site TE-B06003 starting from 21July 2025.

TheTE-B06003 well will be drilled vertically to a planned total depth of approximately 407 metres, targeting multiple coal seams located between 235 and 360 metres. The well will be completed using an “open hole” method - a proven technique optimised for gas recovery in CBM formations. The TE B06003 well is strategically located in close proximity to TE-B06001 and TE-B06002 to enhance reservoir connectivity and maximise productivity.

NuEnergy looks forward to providing further updates as the drilling progresses.
