Kaiser Reef Limited has successfully completed a close-spaced helicopter-supported magnetic and radiometric survey covering 59 square kilometres at the Maldon Gold Project in Victoria.

The low-altitude survey utilized a tight 35-metre line spacing to acquire high-resolution geophysical data across the project area. The resulting data is designed to provide a much clearer picture of the structural architecture and lithology across the goldfield, which remains largely underexplored despite its extensive mining history.

Managing Director Brad Valiukas noted that the survey follows recent soil sampling that highlighted gold trends diverging from the standard regional alignment.

“In the soils, we see some gold trends heading off the north -south alignment, and we are looking for the helicopter-based geophysics survey to confirm , and better define, the cross- cutting structures intersecting the multiple north -south reefs. This will be key to locking in the next series of surface targets for drill testing.”

The geophysical data will be combined with this recent soil survey work and ongoing mapping activities to refine targeting for upcoming drill programs. Surface diamond drilling at Maldon is planned to continue throughout the remainder of 2026 as part of an initial 4,350-metre program designed to test several priority exploration targets.

The Maldon Gold Project has a historical production record of 1.75 million ounces at 28 grams per tonne of gold and is supported by a fully permitted and operating 200,000 tonnes-per-annum carbon-in-leach processing facility at Porcupine Flat.

Prior to completing the airborne magnetic survey, Kaiser commenced underground development of the Northern Drill Drive beneath the Union Hill mine via the existing decline. That milestone marked the first underground development work on site in nearly eight years, establishing a new operating platform to test depth extensions and parallel structures north of existing workings.
