An established, cash-generating gold producer has begun a 4,350m surface drilling campaign at Maldon - a historic, high-grade Victorian goldfield adjacent to a processing facility it already owns.
Kaiser Reef Limited (ASX: KAU) has kicked off a surface diamond drilling campaign at its Quill Gold Target within the Maldon Gold Project in Victoria, marking a renewed exploration effort at one of Australia’s highest-grade historic goldfields.
The Maldon field has historically produced approximately 1.75 million ounces of gold at an average grade of 28g/t - an exceptional grade by any measure - yet much of the district remains underexplored following decades of limited activity.
The campaign is designed to test that potential systematically, and from a position of operational and financial strength.

Maldon pedigree | The field has historically produced 1.75moz at 28g/t Au |
Group resource | 625koz Au in total (Henty 438koz; Maldon/Union Hill 187koz) |
First target | Quill — generated from TSF sterilisation drilling; an earlier hole returned 8m @ 4.16g/t Au (incl. 2m @ 9.90g/t) |
Other targets | Union Hill North, Nuggetty South and Nuggetty (the Nuggetty Reef historically produced ~301koz at ~187g/t) |

Overview
Kaiser Reef is, first and foremost, a gold producer. Its Henty Gold Mine in Tasmania is an established underground operation producing approximately 30,000 ounces per annum, supported by a 199koz Probable Ore Reserve and a conventional 300ktpa processing plant. Henty generates the cash flow that underpins the wider business.
The Maldon Gold Project, in Victoria’s historic Golden Triangle, provides the company’s principal growth optionality. Kaiser owns a fully permitted, operating 200ktpa carbon-in-leach (CIL) processing facility at Maldon, together with existing underground access. With the processing infrastructure already established, the key requirement is additional mineable ore — and the district’s history indicates considerable scope to define it.
The result is an unusual profile for an exploration story: a cash-generating operation on one hand, and a high-grade, under-drilled district with its own processing facility on the other. The current campaign is intended to convert that latent potential into defined resources, funded from internal cash flow rather than dilutive equity raisings.

Asset & category | Tonnes (Mt) | Grade (g/t Au) | Au (koz) |
Henty, Tasmania — Resource | 4.11 | 3.32 | 438 |
Maldon (Union Hill), Victoria — Resource | 1.31 | 4.4 | 187 |
Group total — Resource | 5.42 | 3.59 | 625 |
Henty, Tasmania — Ore Reserve (Probable) | 1.89 | 3.28 | 199 |
Why Maldon Matters
Maldon is not a speculative greenfield prospect. It is a proven goldfield that produced approximately 1.75 million ounces at 28g/t before activity wound down — a grade profile rarely encountered in modern exploration. Kaiser’s thesis is straightforward: an extended period of limited exploration has left a district-scale opportunity adjacent to processing infrastructure the company already controls.

The existing resource base reinforces the case. The Union Hill deposit hosts 187koz at 4.4g/t, while the historic Nuggetty Reef is estimated to have produced around 301koz at approximately 187g/t. Importantly, most of the project’s reef systems remain untested at depth and along strike, and it is these extensions and repetitions that the drilling program is designed to evaluate.
The Drilling Campaign
The initial phase comprises approximately 4,350 metres of surface diamond drilling across four targets, and is expected to be extended and to continue through the remainder of 2026. Kaiser has indicated that it intends to maintain a surface drilling rig over the long term, complementing its ongoing underground activities.

The first target is Quill, a newly defined prospect. It was generated during sterilisation drilling for a proposed tailings storage facility, when hole TSAC_021 returned 8m @ 4.16g/t Au from 10m, including 2m @ 9.90g/t. A subsequent reconnaissance electrical resistivity survey identified a north-south trending zone of high resistivity - interpreted as a potential quartz reef - coincident with that intersection, and this now forms the focus of the follow-up drilling.
Drilling will then progress to Union Hill North, Nuggetty South and Nuggetty. Additional surface targets are being developed through mapping, soil sampling and a planned heli-magnetic survey.

Target | What is being tested |
Quill | New target from TSF sterilisation drilling; earlier hole 8m @ 4.16g/t (incl. 2m @ 9.90g/t); resistivity-defined reef |
Union Hill North | Northern extensions to the Eaglehawk Reef mineralisation |
Nuggetty South | 170m of untested strike; historical results of 3.4m @ 34.0g/t and 4.3m @ 11.2g/t along plunge |
Nuggetty | West lode and remnant targets; the Nuggetty Reef has produced ~301koz at ~187g/t |
Management Commentary
Managing Director Brad Valiukas characterised Maldon as a long-term, district-scale opportunity. “Maldon represents a district-scale gold opportunity for Kaiser, with numerous historical mines and lines of working that remain substantially underexplored, despite having historically produced an enviable 1.75moz at 28g/t,” he said. “We are committed to generating the most value from the entire project… aiming to unlock the district after decades of exploration neglect.”
Mr Valiukas also emphasised the company’s broader strategy, noting its intention to retain a surface rig for the long term, and to maintain a balance sheet capable of supporting both organic growth and potential acquisitions.
Samso Concluding Comments
The Kaiser Reef story is slowly developing and in the midst of a depreciating gold price, the story is just all about doing the business of producing gold. Kaiser Reef Limited is a profitable producer with its Henttyu operations in Tasmania and this release is all about advancing exploration across a historically high-grade, underexplored goldfield adjacent to processing infrastructure it already owns. This is a combination that allows it to pursue growth without the funding pressures typically faced by junior explorers.
Maldon is a substantial history of high-grade production, multiple untested reef systems, an encouraging new target at Quill, and an exploration program funded from internal cash flow. As always, Samso highlights that the principal caveat is equally clear is that historical bonanza grades should not be assumed to reflect what modern drilling will deliver, and the program’s results remain to be demonstrated.
As we digest the information, the key milestones from here are well defined. The initial assays from Quill, followed by results from Union Hill North and the Nuggetty targets as the campaign progresses are what investors should be watching.
The Samso perspectiuve is always about the geology. Taking away the semantics of "mining the market", the technicals are what the market still requires. As they always say, good geology will always lrevail over hype. Hence, for Kaiser Reeef, a producing company with an established mill and a goldfield of Maldon’s pedigree, the forthcoming drill results will be the opportunity.
A Second Exploration Front: Regional Work Begins at Henty
On 1 July 2026, the Company appointed Colin Skidmore as Exploration Manager at the Henty Gold Mine in Tasmania - a dedicated role focused on regional exploration beyond the immediate mine footprint.
Skidmore is an experienced exploration geologist with more than 25 years in senior positions across Australia, Kazakhstan, Canada, the United States, South America and Kosovo.
The appointment gives effect to the regional exploration program flagged in the Company's February 2026 Strategic Plan. Henty sits within the Mount Read Volcanics, one of Australia's most richly endowed mineral belts.
This belt is host to the Rosebery, Mount Lyell, Hellyer and Que River mines - and Kaiser regards its holdings, which contain numerous gold and base-metal occurrences both north and south of the mine, as materially under-explored.
Managing Director Brad Valiukas emphasised the opportunity: "Regionally, Henty has some fantastic exploration potential… as part of a much larger mineralised trend that has received very limited work in modern times," adding that any success would "leverage off our significant infrastructure and existing operating capacity at Henty."
As at Maldon, the work will begin with a period of data consolidation and early-stage activity ahead of drilling, which the Company expects to commence during the coming summer, running in parallel with ongoing in-mine exploration.
