• Drilling has commenced at the Postman's Gully Prospect, representing Koonenberry Gold's first test of the highly prospective Borah Fault
• Initial drill hole 26ENDD023 has intersected multiple breccia zones containing disseminated pyrite, arsenopyrite and quartz-sericite alteration, similar to high-grade rock chips
• Drilling is ongoing at Postman's Gully with results anticipated in May 2026

Koonenberry Gold has commenced an initial diamond drilling program at the Postman's Gully Prospect, representing the company's first test of the Borah Fault Zone, a regional-scale prospective structure parallel to the Sunnyside Shear zone. The drilling is targeting a robust >1.3km long gold in soil anomaly, two NNE-SSE orientated trends of historical workings, and high-grade gold mineralization associated with quartz-sericite-pyrite altered breccia zones. The first drill hole (26ENDD023) has intersected a sequence of variably sericite-quartz-pyrite altered metasediments, with a series of cross-cutting breccia units up to 12.5m in width containing fine grained pyrite, arsenopyrite and associated quartz-carbonate veining. This breccia, alteration and sulphide assemblage has clear similarities to material previously sampled from historical workings which returned up to 14.05g/t Au, providing significant encouragement for the mineralization potential of the Postman's Gully Prospect. Drilling is ongoing at Postman's Gully with results anticipated in May 2026. Outside of the Postman's Gully drilling, the company continues to advance several targets across the Enmore District, including ongoing drilling and geochemical sampling at the Sunnyside Prospect and geophysical programs at the Lachlan Project to define additional drill targets.

Koonenberry Gold is well funded to continue its exploration activities across the Enmore and Lachlan Projects, with $6.3M cash reported at 31/12/2025. The company looks forward to providing regular news flow from its ongoing exploration programs in the coming months.
