Koonenberry Gold (ASX:KNB) has significantly expanded gold mineralisation at its Sunnyside Prospect within the Enmore Project, NSW, extending continuity over +200m strike and to depths exceeding 415m, including broad intervals and high-grade shoots.
- Gold mineralisation extended 195m down dip
- Visible gold in 17 of 22 Sunnyside holes
- Broad zones and high-grade shoots confirmed
- Phase II drilling completed with 35 holes
- Ongoing assays pending at Postman’s Gully and Hand in Hand
Sunnyside Drilling Reveals Deeper and Broader Gold Zones
Koonenberry Gold (ASX:KNB) has delivered a substantial upgrade to its Sunnyside Prospect at the Enmore Project, NSW, with the final three Phase II drill holes confirming extended mineralisation down dip by up to 195 metres. The results show continuity of gold mineralisation across five adjacent drill sections spanning more than 200 metres of strike and reaching vertical depths of up to 415 metres. Notably, hole 26ENDD020 intersected 24 metres at 1.03g/t Au from 172m, including a high-grade 4.6m interval at 8.82g/t Au, with visible gold confirmed in quartz veins. This latest drilling has also identified a potential second plunging shoot, adding complexity and upside to the system.
These findings build on earlier successes, with visible gold intersected in 17 of 22 holes drilled at Sunnyside to date, highlighting the prospect’s emerging bulk tonnage potential alongside high-grade zones. The mineralised system remains open at depth and along strike, particularly along the structurally controlling Sunnyside Shear Zone and NE-trending cross structures. The company’s Managing Director Dan Power emphasised the significance of these extensions and the geological continuity demonstrated by the drilling, which supports planning for the next phase of exploration.
District-Scale Exploration Accelerates with Multi-Prospect Focus
Beyond Sunnyside, Koonenberry has completed 35 holes totaling 8,665 metres during Phase II drilling across the Enmore Project, including 12 diamond holes at Sunnyside, five at Postman’s Gully, and three at Hand in Hand. While results from Postman’s Gully and Hand in Hand are awaited, early geological observations suggest multiple prospective structures with historical high-grade rock chips, such as 14.05g/t Au at Postman’s Gully and widespread anomalous gold at Hand in Hand. The company is also advancing geochemical sampling across the district to develop a robust pipeline of targets.
This district-scale approach is complemented by exploration activities at the Lachlan Project, where geophysical surveys at Dunedoo and Wilga are underway, and a fully funded nine-hole diamond drilling program is scheduled to commence in June at the Junee Joint Venture with Newmont. This JV, where Koonenberry holds a 20% free carried interest, targets large-scale gold systems with potential for multi-million-ounce deposits.
Structural Controls and Geological Insights Inform Future Drilling
The Sunnyside mineralisation is structurally controlled by the Sunnyside Shear Zone and intersecting NE-trending cross structures, with gold hosted primarily within a Permo-Carboniferous granite and adjacent sediments. The mineral system exhibits characteristics analogous to the nearby 1.7Moz Hillgrove Au-Sb deposit, including multi-stage quartz vein arrays and sulphide assemblages. Recent drilling has confirmed mineralisation widths up to 75 metres true width and strike extents over 200 metres, with high-grade zones associated with dilational shoots oblique to the main shear.
Downhole gram-meter pierce points indicate a plunging high-grade shoot to the east, which remains open and requires further testing. The upgrade in hole 26ENDD022, returning 30m at 1.13g/t Au within a broader 94m interval, underscores the potential for additional mineralisation at depth and along strike. These structural and geological interpretations are ongoing and will guide the next phase of drilling.
Capital Structure and Funding Support Exploration Momentum
Koonenberry maintains a market capitalisation of approximately $23.7 million and held $4.45 million in cash as of 31 March 2026, supporting its aggressive exploration programs. The company’s portfolio spans over 4,300 square kilometres across NSW, including 16 granted tenements at the Koonenberry Gold Project, the Enmore Gold Project, and the Lachlan Project. This extensive landholding offers multiple opportunities to leverage structural trends and mineralisation styles proven at Sunnyside.
The ongoing Phase II drilling results at Sunnyside build on previous successes documented in recent months, including visible gold intersections and high-grade zones reported in earlier releases, reinforcing the project’s discovery potential. The company’s strategy to accelerate regional exploration and leverage partnerships such as the Newmont JV at Junee aligns with its objective to delineate Tier 1 gold and copper deposits in Australia’s premier mining jurisdictions.
Investors should note that assay results from Postman’s Gully and Hand in Hand remain pending, and the precise geometry and optimal drill orientation for high-grade shoots at Sunnyside are still under evaluation. These factors will be critical in refining resource estimates and planning future drilling campaigns.

Bottom Line?
Koonenberry’s expanded mineralisation at Sunnyside underscores a growing gold system with multiple high-grade shoots, but pending assays and structural complexities warrant cautious optimism ahead of further drilling.
Questions in the middle?
- How will pending assays from Postman’s Gully and Hand in Hand influence the district-scale resource potential?
- What structural controls govern the distribution of high-grade shoots, and how will this affect future drilling targeting?
- Can the Newmont JV at Junee deliver a significant discovery that complements Koonenberry’s NSW portfolio?
