- Auger geochemical sampling reveals new gold anomalies near Killarney pit
- JORC-compliant nickel resource estimates updated for Rosie and C2 projects
- Strong cash position of A$11.7 million supports ongoing exploration and acquisitions
Killarney Gold Project Acquisition
Duketon Mining Limited has taken a significant step by executing an option agreement to acquire 100% of the Killarney Gold Project, located 63km east of Mount Magnet in Western Australia. This project, covering two granted tenements over 50 hectares, is strategically positioned within a prolific gold-producing region, enhancing its appeal.
Historical rock chip sampling from 2018 revealed extraordinary gold grades, with assays reaching as high as 485 grams per tonne (g/t) of gold. Recent sampling in 2025 has confirmed these findings, returning grades above 30 g/t, underscoring the project's potential. Notably, previous small-scale mining extracted approximately 20 kilograms of gold from just four tonnes of material, highlighting the high-grade nature of the deposit.
Exploration Advances and New Anomalies
During May 2025, Duketon completed an auger geochemical sampling program across the Killarney tenements, collecting 317 samples on a detailed grid. This work identified a previously unrecognized gold anomaly extending 250 meters with gold concentrations up to six times the background levels. This anomaly lies just 80 meters north of the historic Killarney pit and aligns with interpreted geological structures, suggesting further exploration upside.
Additional rock chip assays from the southeast corner of the tenement returned grades up to 90 g/t gold, reinforcing the prospectivity of the area. Duketon plans to follow up with reverse circulation drilling to test beneath these high-grade surface results, aiming to delineate the extent and continuity of mineralization.
Barlee Project Soil Survey and Future Drilling
At the Barlee Project, Duketon completed a soil orientation survey over historic gold-in-soil anomalies. This survey is designed to refine sampling and assay methods ahead of planned infill soil sampling and air core drilling. The objective is to define drill targets that could unlock further gold discoveries within this emerging project area.
Nickel Resource Updates at Rosie and C2
In parallel with its gold exploration, Duketon updated its JORC-compliant mineral resource estimates for its flagship nickel projects, Rosie and C2, located within the Bulge Complex. The Rosie resource now stands at 2.77 million tonnes grading 3.27% nickel equivalent, containing over 56,000 tonnes of nickel and significant quantities of copper, cobalt, and platinum group elements (PGEs). Over 72% of this resource is classified as Indicated, providing a solid foundation for future development.
The C2 resource totals 8.06 million tonnes at 0.57% nickel, with over 99% classified as Indicated. Combined, the Bulge Complex hosts more than 102,000 tonnes of nickel and 254,000 ounces of PGEs, positioning Duketon as a notable player in the nickel sector.
Financial Position and Strategic Outlook
At the end of June 2025, Duketon reported a strong cash and liquid asset position of A$11.7 million, including A$9.3 million in cash. This financial strength supports the company’s three-pronged strategy – advancing exploration on existing tenements, acquiring new tenure opportunistically, and expanding nickel resources through studies and targeted drilling.
With ongoing exploration programs, upcoming drilling campaigns, and a growing resource base, Duketon Mining is well-positioned to enhance shareholder value and capitalize on the rich mineral endowment of Western Australia’s Mount Magnet region.
Bottom Line?
Duketon’s strategic acquisition and resource upgrades set the stage for a pivotal year of exploration and development.
Questions in the middle?
- Will Duketon exercise the option to fully acquire the Killarney Gold Project within the next 12 months?
- How will upcoming drilling results at Killarney influence the company’s valuation and project prioritization?
- What are the timelines and capital requirements for advancing the Rosie and C2 nickel projects toward production?
