Full Summary

Kaiser Reef Limited (ASX: KAU) has announced the results of a recent drilling program targeting the historical Union Hill waste dumps at the Maldon Gold Project, as well as an estimate of the stockpile material. The company has successfully converted the Union Hill waste dumps into a low-grade stockpile, which is estimated to be 566kt @ 0.48g/t for 8,649oz Au. This stockpile will underpin continued processing at the Porcupine Flat Processing Plant until 2030, with the plant currently processing only Union Hill low-grade stockpile material at a rate of 10,000t/month. The company has also provided an update on the Maldon Gold Project, including the commencement of a highly experienced Exploration Manager and Project Manager, as well as data compilation and exploration preparation activities. Kaiser is also in the process of applying for permits to allow the reclamation of Nuggetty surface stockpiles, based on surface sampling and historical bulk sampling. The company's Managing Director, Brad Valiukas, commented that Maldon represents a district-scale gold opportunity for Kaiser, with numerous historical mines and lines of working that remain substantially underexplored.

Outlook

Kaiser is focused on continued processing operations at the Porcupine Flat Processing Plant using the Union Hill low-grade stockpile, while also advancing exploration and development activities across the broader Maldon Gold Project.
