Koonenberry Gold Advances Drill-Ready Copper-Gold Targets at Dunedoo Project

Porphyry Copper-Gold Target Emerges at Bolinda Vale

Koonenberry Gold (ASX:KNB) has outlined a compelling porphyry copper-gold target at its 100%-owned Dunedoo Project in the Lachlan Fold Belt, NSW. The Bolinda Vale Prospect stands out with a near-surface, drill-ready target defined by a suite of multidisciplinary evidence. Geological mapping revealed zoned hydrothermal alteration typical of porphyry systems, including siliceous gossan, phyllic, advanced argillic, and propylitic assemblages.

Supporting this, geophysical surveys detected a substantial 3D magnetic high exceeding 0.5km by 0.3km, interpreted as a buried intrusive complex, coupled with a large 1.6km by 0.45km Induced Polarisation (IP) chargeability anomaly. The IP anomaly, alongside a semi-coincident resistivity break, suggests a pyrite-rich hydrothermal halo consistent with porphyry mineralisation. Soil geochemistry further bolsters the target with a coherent copper-gold-molybdenum anomaly spanning over 800m by 400m, including elevated molybdenum, tellurium, and selenium signatures in rock chips.

Epithermal Gold and Silver Prospects at Hillside and Tucklan

Beyond Bolinda Vale, Koonenberry has delineated promising epithermal gold and silver targets at the Hillside and Tucklan prospects. Hillside features a gold-in-soil anomaly exceeding 0.7km by 0.5km with rock chip assays up to 1.24g/t Au, while Tucklan hosts a similarly sized gold anomaly with high-order silver values reaching 2.11g/t Ag. These targets share mineralisation styles akin to the nearby 491Moz silver-equivalent Bowdens Silver Mine, located about 68km to the south.

Drill Permits Secured for Q3 2026 Campaign

Koonenberry has secured drill permits to test the undrilled Bolinda Vale, Hillside, and Tucklan targets, with a program slated for Q3 2026. The company plans to utilise relatively shallow reverse circulation (RC) drilling to evaluate the porphyry and epithermal systems. Chairman Paul Harris highlighted the potential scale of the Bolinda Vale target, emphasising the coincident geophysical anomalies and supportive surface geochemistry that warrant prompt testing.

District-Scale Potential Across Dunedoo Project

The Dunedoo Project spans approximately 97km² and hosts a pipeline of targets along more than 12km of strike. Extensive soil geochemical datasets reveal multiple gold, copper, and silver anomalies beyond the priority prospects, underscoring a district-scale exploration opportunity. The project lies within the Macquarie Arc, a world-class mineral province that includes major deposits like Cadia and North Parkes.

Koonenberry’s exploration strategy integrates ongoing geophysical and geochemical surveys to refine these targets ahead of drilling. The company’s broader Lachlan Fold Belt portfolio is also advancing, including the recent Gundagai acquisition and a farm-in joint venture with Newmont at Junee, where drilling is underway. These activities position Koonenberry to leverage multiple avenues for discovery across NSW.

Exploration Momentum Builds Amid Regional Activity

The Dunedoo targets complement Koonenberry’s active programs elsewhere in the Lachlan Fold Belt. Notably, Newmont has commenced a fully funded diamond drilling campaign at the Junee JV, targeting significant gold-in-soil anomalies, with results expected later this year. Meanwhile, Koonenberry continues to advance high-grade gold targets at its Enmore Project, including Sunnyside and Borah, where recent drilling has extended mineralisation and secured additional permits.

This coordinated exploration approach across multiple projects underscores Koonenberry’s ambition to unlock Tier 1 gold and copper systems within one of Australia’s most prospective mineral belts.
