Koonenberry Gold Extends Sunnyside Mineralisation with Visible Gold in Multiple Holes

Sunnyside Prospect Shows Depth and Grade Potential

Koonenberry Gold (ASX:KNB) has pushed the boundaries of its Enmore Project’s Sunnyside Prospect, extending gold mineralisation from surface to over 415 metres vertically with a strike length exceeding 260 metres. The latest diamond drilling phase delivered broad zones of bulk tonnage mineralisation alongside high-grade intervals, including standout intercepts such as 44.5m at 1.01g/t Au from 340m and 31m at 1.11g/t Au from 41m, featuring a blistering 0.5m at 62.3g/t Au.

Visible gold was identified in 17 of the 22 holes drilled to date at Sunnyside, underscoring the prospect’s potential for further extensions. Two of the three remaining holes pending assays also contained visible gold, suggesting that the mineralised system remains open both at depth and along strike. The mineralisation is structurally controlled by the Sunnyside Shear Zone and intersecting northeast-trending cross structures, which appear critical in localising higher-grade shoots.

This latest drilling campaign builds on earlier successes, including the Phase II results reported in February that first defined mineralisation to 415m depth. The ongoing program is systematically stepping out 80–110m vertically, aiming to establish continuity and test the plunge of high-grade zones. The company’s approach reflects a disciplined effort to delineate a district-scale gold system with both bulk tonnage and high-grade components.

Hand in Hand RC Drilling Confirms Shear Zone Fertility

Complementing the diamond drilling at Sunnyside, Koonenberry’s reverse circulation (RC) program at the Hand in Hand Prospect returned encouraging results from 15 holes totaling 1,864m. Despite groundwater challenges limiting hole depth, 11 of 15 holes delivered significant gold intersections exceeding 2g/t x metre, confirming the shear zone’s prospective nature. Intercepts such as 24m at 0.28g/t Au and 46m at 0.28g/t Au with higher-grade internal intervals indicate a fertile structural corridor extending east from Sunnyside.

The RC drilling has refined the geological model, identifying the granite-sediment contact and phyllic alteration zones similar to Sunnyside. Planned diamond drilling aims to test these targets at depth, assisted by recent Gradient Array IP geophysics designed to highlight northeast-trending cross structures. This integrated approach could unlock better-defined high-grade zones within the broader mineralised system.

District-Scale Exploration Accelerates Across Enmore

Koonenberry is not limiting its ambition to Sunnyside and Hand in Hand. The company is actively exploring multiple fault zones across the Enmore Project, including the Borah, Sheba, and Chandler faults. Surface geochemical sampling and Gradient Array IP surveys are underway to generate new drill targets. Notably, drilling has commenced at the Postman’s Gully Prospect along the Borah Fault Zone, where early holes intersected breccia zones with sulphide mineralisation akin to historical high-grade rock chip samples exceeding 14g/t Au. Assay results from this program are expected soon.

The Chandler Fault corridor is also a priority given its structural similarity to the nearby Hillgrove gold-antimony mine, located just 20km northeast. Koonenberry’s focus on these parallel structures reflects a strategic push to demonstrate district-scale potential, supported by a pipeline of targets generated from ongoing geochemical and geophysical programs.

Lachlan Project and Joint Ventures Progress

Beyond Enmore, Koonenberry completed an induced polarisation (IP) survey at the Dunedoo Gold-Silver-Copper Project within its Lachlan portfolio. The survey covered part of an 8km gold-in-soil epithermal-porphyry trend, with interpretation pending. Plans are also underway for IP geophysics at Wilga Flats, near the Cowal Gold Mine, and drilling at the Junee Joint Venture, which is farmed out to Newmont Exploration. These initiatives broaden Koonenberry’s exposure to Tier 1 gold and copper systems in NSW.

Financial Position Supports Active Exploration

As of 31 March 2026, Koonenberry held $4.45 million in cash with no debt, providing a solid foundation for its aggressive exploration agenda. Operating expenditure for the quarter was $298,000, with $1.49 million spent on exploration activities, including drilling, sampling, and assays. The company’s capital management remains prudent, having distributed Junior Minerals Exploration Incentive tax credits to investors during the quarter.

Managing Director Dan Power emphasised the company’s confidence in its NSW portfolio, highlighting the steady news flow expected from ongoing drilling and geophysical programs across Enmore and Lachlan projects. This follows recent Koonenberry Gold Drills High-Grade Postman’s Gully results that spotlight the potential along parallel fault zones.
