Gorge Project – Field Reconnaissance Completed

04 June 2026 GEO Exploration Limited ("GEO " or the "Company") Gorge Project - Field Reconnaissance Completed GEO Exploration Limited (AIM: GEO) is pleased to confirm that the initial field reconnaissance programme at the Gorge Project in Western Australia has now been completed. This work forms part of the Company's 2026 exploration programme and follows the recent airborne LiDAR, aerial photography, magnetic and radiometric surveys which were completed ahead of schedule. The field activities were led by GEO's Exploration Manager, Tom Harris, and included validation of historical geochemical results, confirmation of historic workings and drill locations, geological mapping and completion of orientation soil geochemical survey work over known areas of surface gold mineralisation. This work is intended to refine analytical methods and survey design for the proposed broader geochemical programme over the approximately 5km strike of historical workings previously identified at Gorge. The Company considers the field trip to have been highly productive. The field data will now be reviewed and interpreted by the Company's technical team. GEO will aim to provide further updates to shareholders on the outcomes of the reconnaissance work and interpretation in due course. Callum Baxter, Technical Consultant to GEO Exploration Limited, commented: "It is pleasing to have completed the initial field reconnaissance at Gorge. Very important information has been collected which will allow efficient execution of future field activities including a broad geochemical survey of the areas of known gold mineralisation. I look forward to further progress in the coming weeks." Tom Harris, Exploration Manager of GEO Exploration Limited, commented: "I am thrilled with the potential seen on the ground at Gorge. I thank the field team for completing the activities in a productive and safe manner. I am excited to see the incoming results and analysis from geochemical samples collected in addition to those from the recently completed airborne geophysical surveys." Omar Ahmad, Chief Executive Officer of GEO Exploration Limited, commented "We are pleased to confirm completion of the initial field reconnaissance at Gorge, marking another key step in advancing our 2026 exploration programme. The trip was very positive, with the team completing all planned objectives and gathering valuable geological information that strengthens our understanding of the Gorge Project, and the initial signs are exactly what we were expecting to see. Momentum continues to build as we move through a disciplined, systematic exploration process ahead of our maiden drilling campaign, and shareholders can expect further updates shortly as the reconnaissance findings and technical interpretation are finalised." Gorge Project Overview The Gorge Project (Exploration Licence E08/3737), located approximately 110km west of Paraburdoo in Western Australia, covers an area of 81 square kilometres within the Proterozoic aged Capricorn Orogen. GEO recently acquired the licence, through its 100% owned subsidiary Gorge Gold Pty Ltd. The Gorge project is considered highly prospective for large scale gold systems of Orogenic-type or Carlin-type. Limited historical exploration at Gorge has identified widespread gold mineralisation across the licence area. Gold occurrences have been recorded over approximately 5km of strike, supported by drainage, soil and rock chip sampling, historic workings, and alluvial and eluvial gold mining. Historical results include: · Rock chip samples returning gold values up to 134g/t Au · Soil samples returning gold values up to 233g/t Au · Drainage sampling returning elevated gold values · Recovery of multiple gold nuggets from near surface, ranging from <2g to in excess of 100g These results along with the proximity of the nugget recoveries suggests the potential presence of a primary bedrock gold source within the licence area.
