• Final bottom-hole location confirmed targeting Upper and Lower Tweedel reservoirs
• Surface drilling location optimised to reduce site preparation costs and environmental disturbance
• Additional upside potential identified in the Homeseeker B sand interval

Galilee Energy Limited (ASX: GLL) has finalised the well location and drilling configuration for the Zydeco-1 appraisal/production well at its 100%-owned Zydeco Gas Project in Acadia Parish, Louisiana. The final Bottom Hole Location (BHL) has been confirmed following integration of recent 3D seismic interpretation and geological modelling, maximising exposure to the Upper and Lower Tweedel reservoir intervals, which represent the primary targets. The Company's drilling team has also reviewed the optimal Surface Hole Location (SHL) to improve operational efficiency and minimise site preparation requirements. While the primary targets remain the Tweedel gas formations, the Zydeco-1 well will also evaluate the Homeseeker B sand interval, which regional data and seismic interpretation indicate may contain potential oil charge. This interval is not currently included in the Company's prospective resource estimate and represents an opportunity to significantly improve the project's economics. The well is designed as a multi-objective appraisal and production well capable of testing and, if successful, completing both Tweedel reservoirs and the Homeseeker B sand. Galilee continues to target spudding the Zydeco-1 well during 2Q 2026, subject to final regulatory approvals.

Zydeco-1 represents a key catalyst for Galilee as the Company progresses its strategy to establish production in the United States, which the Company expects to be the first in a series of value accretive wells to follow.
