Koonenberry Gold has launched diamond drilling at the Postman’s Gully Prospect within its Enmore Project, targeting a promising parallel fault zone with historical high-grade gold. Early drill results reveal encouraging geological features, with assays expected by May 2026.
- Drilling commenced at Postman’s Gully targeting Borah Fault Zone
- Initial hole intersected multiple breccia zones with sulphide mineralisation
- Historical rock chips show high-grade gold up to 14.05g/t
- Ongoing exploration across Enmore and Lachlan Projects
- Strong cash position of $6.3 million supports continued drilling
Exploration Advances at Postman’s Gully
Koonenberry Gold Ltd (ASX:KNB) has initiated diamond drilling at the Postman’s Gully Prospect, a key target within its Enmore Gold Project in New South Wales. This marks the company’s first drill test of the Borah Fault Zone, a significant regional structure running parallel to the well-known Sunnyside Shear Zone, which hosts broad and high-grade gold mineralisation.
The Postman’s Gully area is defined by a robust gold-arsenic soil anomaly extending over 1.3 kilometres in strike and 0.65 kilometres in width, with historical workings that have yielded rock chip samples grading up to 14.05 grams per tonne (g/t) gold. These historical samples also show associated quartz-sericite-pyrite alteration and visible gold, suggesting a strong mineralisation system.
Promising Early Drill Results
The initial diamond drill hole, 26ENDD023, intersected multiple breccia zones up to 12.5 metres downhole, containing disseminated pyrite, arsenopyrite, and quartz-sericite alteration. These geological features closely resemble those found in the high-grade rock chips from historical workings, providing encouraging evidence that the mineralisation extends at depth.
Drilling is ongoing, with assay results from Postman’s Gully expected in May 2026. Meanwhile, results from three remaining drill holes at the Sunnyside Prospect, including two with visible gold, are anticipated in April 2026. These programs are part of a broader Phase II drilling campaign aimed at expanding the known mineralised zones and testing new targets along multiple prospective fault structures within the Enmore district.
Broader Exploration and Funding
Beyond Postman’s Gully, Koonenberry Gold is actively advancing exploration across its extensive portfolio in NSW, including the Lachlan Project. The company is conducting geological reconnaissance, soil sampling, and geophysical surveys to identify further drill targets along the Borah Fault Zone and other underexplored structures such as the Sheba and Chandler Fault Zones.
With a strong cash balance of $6.3 million as of 31 December 2025, Koonenberry Gold is well positioned to sustain its exploration momentum. The company also benefits from joint ventures with Newmont Exploration, which is preparing for drilling programs at the Junee and Fairholme projects, further enhancing the potential for significant discoveries.
District-Scale Discovery Potential
The Enmore Project is shaping up as a district-scale gold discovery opportunity. Recent drilling at Sunnyside has confirmed broad zones of gold mineralisation from surface to over 415 metres vertical depth, with high-grade intervals that underscore the prospect’s potential. The ongoing expansion of soil geochemical anomalies and new drill targets like Postman’s Gully reinforce the view that this region could host substantial gold resources.
Koonenberry Gold’s strategic focus on multiple parallel structures and its systematic exploration approach aim to unlock value across its portfolio. The company’s diverse holdings, including several 100% owned projects and joint ventures, position it as a notable player in NSW’s gold and copper exploration landscape.
Bottom Line?
As drilling progresses and assays come in, Koonenberry Gold’s Enmore Project could redefine NSW’s gold exploration landscape.
Questions in the middle?
- Will Postman’s Gully assays confirm continuity of high-grade gold mineralisation?
- How will results from Sunnyside’s visible gold drill holes influence resource estimates?
- What new targets might emerge from ongoing soil and geophysical surveys along Borah and other fault zones?
