Kuniko Limited’s initial diamond drilling at the Commonwealth-Silica Hill Project has intersected significant massive sulphide mineralisation, confirming down-plunge continuity and prompting an accelerated Phase II drilling campaign backed by fresh funding.
- Three diamond holes completed with massive and disseminated sulphide intersections
- Down-plunge step-outs confirm continuity of the Main Shaft massive sulphide lens
- Visible silver sulphosalts found in Silica Hill hole, indicating strong mineralisation
- Phase II drilling accelerated and funded by $3.75 million placement
- Impact Minerals retains 30% free-carried interest until decision to mine
Early Drilling Success at Commonwealth-Silica Hill
Kuniko Limited has reported promising early results from its Phase 1 diamond drilling program at the Commonwealth-Silica Hill Project, located in the Lachlan Fold Belt of New South Wales. Three holes, totaling 540 metres of a planned 1,200-metre program, have intersected significant sulphide mineralisation, including thick intervals of massive and semi-massive sulphides. These findings reinforce the potential of the project as a high-value gold, silver, and base metals deposit.
Specifically, holes CMKNI001 and CMKNI002 at Commonwealth Main Shaft intersected 3.7 metres and 2.9 metres of massive sulphide respectively, within broader zones of disseminated and stringer sulphides. These represent down-plunge step-outs from known mineralisation, confirming the continuity of the Main Shaft massive sulphide lens, which remains open at depth and along strike. Meanwhile, hole CMKNI003 at Silica Hill intersected approximately 60 metres of disseminated and stringer sulphide mineralisation, including visible silver sulphosalts such as proustite, highlighting strong mineralised continuity.
Strategic Implications and Project Context
The Commonwealth Project is notable for its gold-rich volcanogenic massive sulphide (VMS) system, with geological similarities to the world-class Eskay Creek deposit in Canada’s Golden Triangle. Impact Minerals, the project’s tenement holder, has previously defined JORC Inferred Mineral Resources of 88,800 ounces of gold and 3.3 million ounces of silver, alongside significant base metals credits. The recent drilling by Kuniko aims to test extensions of this mineralisation and newly identified targets from a recent MobileMT geophysical survey, which revealed a 4-kilometre conductive corridor beyond existing resources.
Importantly, Kuniko’s exploration is supported by a $3.75 million placement that funds an accelerated Phase II drilling campaign. This next phase will focus on resource validation and expansion, as well as testing high-priority regional targets identified through geophysical and geochemical programs. Impact Minerals retains a 30% free-carried interest until the decision to mine, providing substantial leverage to exploration success while limiting near-term capital exposure.
Looking Ahead: Drilling and Exploration Pipeline
Drilling is progressing well, with the remaining three holes of Phase 1 expected to be completed within weeks and assay results anticipated in April 2026. These will target the Northern Lode at Silica Hill, an untested induced polarisation anomaly at Commonwealth South, and down-plunge extensions at Commonwealth South. Concurrently, Kuniko is advancing exploration at other prospects within the project area, including Gladstone West and Geenobby, where recent soil and rock chip sampling has yielded encouraging high-grade gold-silver results.
The combination of early drilling success, robust funding, and a growing pipeline of district-scale targets positions the Commonwealth-Silica Hill Project for a potentially transformative exploration campaign. The project’s location within the prolific Lachlan Fold Belt, home to major mining operations, further underscores its strategic significance.
Bottom Line?
With massive sulphides confirmed and Phase II drilling accelerated, the Commonwealth-Silica Hill Project is poised for a pivotal exploration phase that could reshape its valuation and development trajectory.
Questions in the middle?
- What assay results will confirm the economic viability of the massive sulphide intersections?
- How will Phase II drilling outcomes impact the current JORC resource estimates and joint venture dynamics?
- What is the potential scale and grade of the deeper copper-gold porphyry targets suggested by recent drilling?
