Special Report: Koonenberry Gold’s first diamond hole drilled at the Sunnyside prospect within its Enmore project in northeast NSW returned a 170m intersection grading 1.75g/t gold from 77m.
This includes an 18.3m interval at 9.95g/t gold from 172.9m that coincides with previously reported visible gold zones and is associated with intense multiphase veining, sulphides and breccia.
Koonenberry Gold (ASX:KNB) reported observing visible gold in multiple zones from a down-hole depth of 172.8m to 191.25m in hole 25ENDD001 in mid-February 2025.
The new assays validate historical results, as 25ENDD001 was drilled as a diamond core twin of historical reverse circulation hole OSSRC006 that returned 174m at 1.83g/t gold from surface including 3m at 8.86g/t from 172m.
Results also provide further evidence of this system’s potential to host broad intervals of gold mineralisation, along with high-grade gold zones. Gold mineralisation remains open up-dip in the preferred granite host rock, along strike and at depth.
Results from 25ENDD001 bode well for assaying of the next three, holes where visible gold was also observed.
Drilling of a fifth hole is underway, with about 1400m of the estimated 3000m drill program remaining.
“This hole was planned to target high-grade vein sets at a high angle to the main shear zone and we have certainly demonstrated the potential for this system to carry exceptionally high gold grades as well as verified the broad zones of gold mineralisation intersected in historical drilling,” KNB managing director Dan Power said.
“Samples from holes 25ENDD002, 003 and 004, which all intersected visible gold, are now at the lab and will be reported through April.
“Drilling at Sunnyside is ongoing and continues to target extensions to the system, which we have demonstrated to have a 240m vertical depth extent on three sections, A-A’, B-B’ and C-C’.”
KNB drilled 25ENDD001 to test potential high-grade vein sets at a high angle to the shear zone while validating historical results, both of which were achieved.
Broad zones of gold mineralisation are associated with observed disseminated sulphides and quartz-iron carbonate-sulphide veining.
The hole also encountered clear evidence of multiple orientations of veining, with at minimum a primary set controlled by the main shear, as well as a second order cross cutting set dipping across the shear and granitic fabric.
KNB noted that it remained unclear which direction is the most ideal for drilling while interrogation of structural information was ongoing.
However, the company expects its geological model and knowledge of the structural, mineralogical and alteration relationships to develop as drilling continues, which will in turn improve its understanding on the controls of mineralisation.

KNB is continuing its maiden diamond drilling program at Enmore to test the impressive widths and grades of gold mineralisation previously recorded at Sunnyside.
This is expected to further improve its understanding of the controls on mineralisation and identify the optimal drilling direction for the high-grade shoots while expanding the mineralised footprint.
Results from the program will be used to design follow-up diamond drilling to test the continuity of mineralisation at Sunnyside in multiple directions, including along the 125m x 550m prospective structural corridor.
The company will use results from soil sampling to plan drilling at other prospects at Enmore.
