Announcement PDF strike@strikeenergy.com.au ABN 59 078 012 745 www.strikeenergy.com.au 1, 40 Kings Park Rd, West Perth WA 6005 Walyering West Update • Walyering West - 1 flow testing commenced with initial operations recovering hydrocarbons to surface from the C 1 sand . • Testing program to include the A Sub1 , C 1 and D1- D4 sands within the primary target of the Cattamarra Formation . • Testing program and evaluation expected to be completed by end June . • Walyering gas field production temporarily suspended to facilitate the installation of field compression facilities. Strike Energy Limited (Strike - ASX: STX) advises that flow testing operations have commenced at the Walyering West - 1 exploration well, located in Production Licence L23 (100% net to Strike) in the Perth Basin . The testing program is designed to evaluate reservoir productivity and gather pressure and flow rate data from the A Sub1, C 1 and D 1- 4 sands within the primary target of the Cattamarra Formation, following the successful drilling and completion of the well . F low testing operations conducted over the C 1 Sand ha ve successfully flowed hydrocarbons to surface , with testing ongoing . Data acquisition, including flow rate and pressure information, is continuing and remains subject to further analysis with testing and interpretation expected to conclude by 30 June 2026 . Walyering Gas Processing Facility Update Production from the Walyering gas field is undergoing a planned shutdown to facilitate the installation and commissioning of field compression facilities. The compression project is progressing as planned, with facility restart anticipated 10 June 2026 and commissioning activities expected to be completed in late June 2026. The installation of compression is expected to enhance reservoir recovery and support continued production from the Walyering gas field. ASX: STX The Company Announcement Officer ASX Ltd via electronic lodgement 9th June 202 6 Initial flow test operations at Walyering West-1 2 Commenting on the commencement of flow testing, Strike Managing Director and Chief Executive Officer, Shelley Robertson said: “The Walyering West - 1 flow testing program is an important step in evaluating the commercial potential of the Walyering West discovery and its ability to contribute to future production from the Walyering field. If flow testing is successful and demonstrates economically recoverable hydrocarbons, Walyering West could provide an opportunity to support existing production and contract commitments, while leveraging Strike’s established infrastructure position in the Perth Basin. I look forward to updating shareholders on the outcomes of the testing program." About the Walyering West-1 Exploration Campaign The Walyering West - 1 well is located at Lat: 30° 43' 40.00" S, Long: 115° 27' 00.52" E. The well was drilled to a Total Depth of 3,650m MDRT to test Jurassic aged conventional sandstone reservoirs within a fault bound, 4 - way dip closure. Walyering West - 1 is located approximately 2 kilometres west of the producing Walyering - 5 gas well where pre - drill estimates interpreted a potential 2U Prospective Resource of 46 PJ 1 within the A to D Sands of the Cattamarra Formation. On success, and subject to the results of the current flow testing, Walyering West - 1 will be tied into the Walyering Gas Processing Facility located approximately 3 kilometers to the north east . Prospective Resource Estimate Information & Cautionary statement: The above estimated quantities of petroleum that may potentially be recovered by the application of a future exploration and development project(s) relate to undiscovered accumulations. These pre - drill estimates are un - risked, probabilistically determined, and have both an associated chance of discovery of 26% and a chance of development estimated to be 90%. Further exploration, appraisal and evaluation is required via drilling and testing to determine the existence of a significant quantity of potentially moveable hydrocarbons. 1 Refer to the Important Notices for Resource Information. 3 This announcement is authorised for release by the Managing Director and Chief Executive Officer in accordance with the Company’s Continuous Disclosure Policy .
