Kaiser Reef has initiated underground development at the Union Hill Gold Mine, marking a significant step in unlocking the Maldon Gold Project's exploration and production potential.
- First underground development cut at Union Hill after eight years
- Northern Drill Drive enables testing of multiple reef lines
- Project supported by fully permitted plant and mining lease
- Maldon historically produced 1.75 million ounces at 28g/t
- Kaiser Reef remains profitable with strong balance sheet
Underground Development Resumes at Union Hill
Kaiser Reef Limited (ASX:KAU) has taken a major step forward at its Maldon Gold Project by commencing underground development at the Union Hill Gold Mine, the first such activity in nearly eight years. The company has completed the initial cut of the Northern Drill Drive, a critical milestone that establishes a new platform for underground exploration and potential future mining.
The development will enable drill testing of several key reef lines north of existing workings, including Eaglehawk, Linscott’s, Ladies, and Sailor’s Reefs. This strategic move aims to unlock high-grade targets that remain substantially underexplored despite the area’s rich historical production.
Strategic Advantage of Maldon’s Infrastructure
Maldon’s appeal extends beyond its historical pedigree, having produced an impressive 1.75 million ounces of gold at an exceptional grade of 28 grams per tonne. Kaiser Reef benefits from a fully permitted and operational 200,000 tonnes per annum carbon-in-leach (CIL) processing plant, an active mining lease, and existing underground access via a decline. These assets provide a strong foundation for both exploration and potential production expansion.
Managing Director Brad Valiukas emphasised the significance of the milestone: “It’s a milestone for both the Maldon Gold Project and Kaiser to have jumbo development underway beneath Union Hill, establishing this new drill platform for exploration.” He highlighted that the company has already begun stripping narrow sections at the top of the decline in preparation for future haulage, signaling a clear intent to advance the project.
Exploration and Production Outlook
Underground drilling from the new development is central to Kaiser Reef’s strategy to define additional Resources and pave the way for the next phase of development. The company is focused on maximising value across the Maldon Project, combining exploration growth with a path toward increased production.
Kaiser Reef remains a profitable gold producer with a robust balance sheet and a pipeline of exploration and development opportunities. Its dual processing infrastructure, including the established Henty Gold Mine in Tasmania, positions the company to capitalise on a strong gold price environment while advancing its Victorian assets.
This renewed underground activity follows recent surface exploration successes, including soil surveys and drilling campaigns that have identified extensive gold anomalism across the Maldon district, reinforcing the project’s district-scale potential.
Bottom Line?
Kaiser Reef’s underground development at Union Hill signals a tangible step toward unlocking Maldon’s high-grade potential, but the pace and scale of resource definition will be critical to watch.
Questions in the middle?
- How quickly will underground drilling translate into updated resource estimates?
- What are the timelines and capital requirements for moving from exploration to production expansion?
- How will recent surface exploration results integrate with underground targets to shape the project’s growth?
