Full Summary

Kaiser Reef Limited (ASX: KAU) is pleased to announce drilling results for its recently completed diamond drilling program, within the Union Hill Open Pit, at the Maldon Gold Project. The 22-hole, 960-metre in-pit program targeted unmined extensions of the Eaglehawk Reef beneath the pit floor, with 18 holes intersecting gold mineralisation. Significant intercepts include 5.8m @ 5.37g/t Au, 6.9m @ 6.05g/t Au, and 8.6m @ 4.99g/t Au. The drilling confirmed grade continuity along a 160-metre strike length, with the mineralised zone lying adjacent to existing underground access. Two holes unexpectedly hit historical workings, with one hole abandoned early. The Eaglehawk Reef is a curvilinear quartz vein structure with strong vertical continuity and localised faulting. Gold mineralisation is primarily hosted within the western hanging-wall vein arrays, associated with sericite alteration and trace disseminated sulphides. The Union Hill in-pit drilling results reinforce the continuity of mineralisation within the Eaglehawk Reef and confirm the presence of high-grade spur veins, providing a robust technical foundation for further evaluation and exploration.

Outlook

The next step at Union Hill will be to re-establish the underground as an exploration platform, with plans to commence active work on re-accessing and rehabilitating the decline in January to allow follow-up drilling. Additionally, the company plans to establish a drill position giving access to the north.
