We wish to announce that NuEnergy Gas Limited (“NuEnergy”), a 70% subsidiary of GFB which is listed on the Australian Securities Exchange (“ASX”) has today announced on ASX, the signing of a collaboration agreement (“Agreement”) with PT Beijing Energy Linking (“PT BJEL”) for the development of its coal bed methane (“CBM”) production sharing contracts in South Sumatra Indonesia. Pursuant to the Agreement, NuEnergy shall appoint PT BJEL as the Lead EPCC (Engineering, Procurement, Construction and Commissioning) contractor for the development of the Tanjung Enim production sharing contract (“PSC”) and Muralim PSC subject to the terms and conditions of the respective PSC’s EPCC Contract. PT BJEL shall finance 100% of the field development works at a capped contract price where the contract cost shall be repaid via future gas sales, to be agreed between NuEnergy and PT BJEL, which is to be stipulated in the respective PSC’s EPCC Contract, with immediate focus on the full implementation of Tanjung Enim Plan of Development 1 (“POD 1”). The field development works encompass amongst others, the drilling of a combination of vertical and horizontal wells, construction of surface facilities, in-field pipelines and all integration and testing required to achieve first gas and production ramp up to achieve a sustainable plateau production rate as approved under the POD.

The Agreement shall be deemed terminated upon the occurrence of any of the following events, whichever comes earlier:

1. the termination of this agreement by mutual written consent of all the parties; or
2. Tanjung Enim POD 1’s EPCC Contract is not finalised and signed within 120 days from the date of the Agreement; or
3. material breaches in any of the EPCC Contract under the respective PSC; or
4. insolvency or winding-up of either party.

This collaboration is both timely and strategic, as the development of the Tanjung Enim POD 1 will be fully funded. This provides the certainty required to accelerate execution and enables a seamless transition from NuEnergy’s Early Gas Sales phase of about 1 million standard cubic feet per day (MMSCFD) to a materially higher production plateau of 25 MMSCFD.

PT BJEL is a wholly owned subsidiary of Shanghai Beijing Energy Linking New Energy Development Co LTD (“SBJE”). The major ultimate shareholders of SBJE are Beijing Energy International Holding Co. Ltd (“BJEI”) and Envision Group.

Further details are enclosed in the attached announcement made by NuEnergy.

This announcement is dated 8 January 2026.
