Mechanical Completion and Introduction of First Gas at Akatara

24 June 2024 - Singapore: Jadestone Energy plc ("Jadestone", or the "Company"), an independent upstream company focused on the Asia-Pacific region, is pleased to provide the following update on the Akatara gas development project onshore Indonesia.

On 18 June 2024, the Akatara Gas Processing Facility (the "Facility") achieved the key milestone of mechanical completion, meaning all components and systems of the Facility have been constructed, installed and tested, marking a significant achievement prior to commercial production of the Akatara gas field.

On 22 June 2024, reservoir gas was introduced to the Facility from the Akatara-A4 well, and a period of final commissioning using reservoir gas has now commenced. Condensate is already being processed to the Facility's storage tanks in preparation for sale, with first commercial gas and LPG sales to follow.

Paul Blakeley, President and CEO commented:

"I am delighted to announce this key milestone in the Akatara Project, as we achieve mechanical completion of the gas processing facilities and bring first gas into the plant from an adjacent well pad.  This is a result of tremendous effort by all involved within Jadestone, delivering to a very tough schedule with the help of our key contractors, government regulators and other stakeholders.

"I am particularly proud of the safety-first mindset of the team and delivery of the project without a single lost time injury with over seven million manhours worked to date.  The project now enters the very final phase of commissioning as we move towards delivery of commercial sales gas, condensate and LPG."
