Duketon Mining (ASX:DKM) embarks on second drilling program at Killarney Gold Project

Duketon Mining (ASX:DKM) has commenced its second reverse circulation drill program at the Killarney Gold Project in Western Australia, signalling a continuation of momentum from earlier exploration successes and reflecting a focused effort to both confirm and extend the mineralisation already intersected.

The decision to return to the field so soon after the previous campaign highlights the company’s intent to build a stronger geological picture, to test new anomalies that have emerged from recent geochemical work, and to move closer towards a better understanding of the project’s broader potential.

Highlights

• Reverse circulation drilling program of up to 20 holes for approximately 2,000 metres now underway at the Killarney Gold Project

• Follow-up of earlier high-grade intercepts including 9 metres at 4.64 grams per tonne gold with a 1 metre section grading 39.77 grams per tonne from 54 metres

• Drilling to extend known mineralisation along strike and at depth while testing new auger geochemical anomalies

• Assay results expected within four to six weeks depending on laboratory turnaround times

The Killarney Gold Project is situated about seventy kilometres east of the well-established mining centre of Mt Magnet, one of Western Australia’s historic gold-producing regions, and approximately eight kilometres north of the sealed Mt Magnet–Leinster Road.

This proximity to a mining hub and existing infrastructure provides both logistical advantages and a practical setting for ongoing exploration, ensuring that drilling can be undertaken efficiently and results advanced without the added complication of remoteness that often hinders early-stage exploration campaigns.

The program will comprise close to 2,000 metres of reverse circulation drilling from up to 20 holes, designed with dual objectives.

On the one hand, the drilling seeks to build on promising intercepts already recorded in earlier phases, probing the mineralisation at depth and along strike to test for continuity and size.

On the other hand, the program also aims to assess newly defined targets that were identified through auger geochemical sampling undertaken earlier in the year, adding breadth to the campaign by opening the door to additional zones of mineralisation beyond those already known.

The justification for such an approach lies in the calibre of the results reported in August 2025, where multiple drill holes delivered intersections of noteworthy tenor.

Highlights included ten metres grading 2.33 grams per tonne gold with a three metre section grading 7.24 grams per tonne from 32 metres, nine metres at 2.12 grams per tonne gold from surface with three metres grading 5.5 grams per tonne, and seven metres at 3.45 grams per tonne including three metres at 7.81 grams per tonne from 29 metres.

Of particular interest was an interval of nine metres at 4.64 grams per tonne gold, which hosted a single metre grading 39.77 grams per tonne from 54 metres, illustrating both the persistence of mineralisation and the presence of localised high-grade shoots.

Managing Director Stuart Fogarty noted that the program has been designed to continue the methodical step-out work required to advance the project while also broadening the search into fresh areas.

“The drilling is designed to extend the known mineralisation along strike and at depth, as well as to test a number of additional geochemical targets identified in recent programs,” he said.

This framing captures both the continuity of purpose that comes with returning to known zones and the opportunistic expansion into new ground, creating a balance between consolidation and discovery.

From a corporate perspective, the second drilling campaign at Killarney is an extension of Duketon disciplined approach to exploration, whereby incremental work programs are used to progressively expand the geological picture and provide regular updates to the market.

The expectation is that assays will be received within four to six weeks of dispatch from the drill site, subject to laboratory capacity, ensuring that investors will not be left waiting long before the next round of results is made public.

The Killarney program represents more than just a test of immediate targets, as it embodies a structured attempt to determine whether the early promise revealed in previous drilling can be translated into a more robust body of mineralisation with both scale and continuity.

By focusing simultaneously on depth extensions, strike length and fresh geochemical anomalies, Duketon Mining is taking a comprehensive approach to exploration that avoids overreliance on isolated results and instead aims to build a coherent resource model.

Set against the backdrop of Western Australia’s prolific goldfields, the Killarney Gold Project provides Duketon with a foothold in one of the country’s most productive and well-understood provinces.

With assays due in the coming weeks and a clear strategy for systematically advancing the project, the company is positioned to provide further clarity on the scale of the mineral system, with the results likely to shape the direction of subsequent exploration efforts.
