Kuniko Hits Bonanza Silver Gold Outside Known Silica Hill Envelope

Bonanza Grades Redefine Silica Hill Potential

Kuniko Limited (ASX:KNI) has struck what can only be described as bonanza-grade silver and gold mineralisation at its Silica Hill prospect within the Commonwealth–Silica Hill Project in New South Wales. Drill hole CMKNI004 returned a staggering 0.5m intercept grading 20,603 g/t silver and 27 g/t gold within a massive sulphide vein, a discovery that lies approximately 100 metres outside the previously modelled mineralised envelope. This intercept is interpreted as a feeder-style structure, suggesting a high-grade fluid conduit feeding the broader system.

Structural Controls Unlock New Search Space

The positioning of CMKNI004 relative to the main mineralised domain suggests displacement along a reverse fault, effectively downthrowing the mineralised body at depth. This structural offset has opened a fresh search space beneath the current model, with mineralisation remaining open in all directions. The increase in gold tenor at depth compared to the typically silver-rich upper zones points to vertical metal zonation, consistent with a large, fertile hydrothermal system. Such a scenario raises the prospect of discovering thicker and higher-grade mineralisation down-plunge and along strike.

These findings build on earlier drilling results, including the step-out hole CMKNI003, which confirmed lateral continuity by intersecting 50m at 1.0 g/t gold and 59 g/t silver, extending mineralisation into previously under-drilled areas. The coexistence of very high-grade veins and broad disseminated sulphide zones supports the interpretation of a vertically extensive mineral system hosted within rhyolite sequences. This aligns with the project’s geological setting in the Lachlan Fold Belt, a Tier-1 mining province known for world-class deposits.

Phase 2 Drilling to Expand and Upgrade Resource

Following the impressive Phase 1 results, Kuniko is poised to commence a Phase 2 drilling campaign in June, focusing on larger step-out holes to test the newly defined targets generated from integrated drilling, structural interpretation, and geophysical datasets. The company is particularly targeting extensions of the high-grade feeder zones and potential higher-grade positions at depth. Assays from the remaining two Phase 1 holes are expected within the next fortnight, which could further refine the understanding of the system.

Kuniko’s Managing Director, Maja McGuire, emphasised the significance of the new discovery: “Intersecting grades of 20,603 g/t silver and 27 g/t gold in a massive sulphide vein is an outstanding result and highlights the potential for high-grade zones within the system. We are excited to get back out there and continue drilling, we believe there is much more to come from the Project.”

Project Scale and Strategic Location

The Commonwealth Project lies within the prolific Lachlan Fold Belt, approximately 100 kilometres north of Orange, NSW, a region that hosts major operations such as Newmont’s Cadia-Ridgeway and Evolution Mining’s Northparkes and Cowal mines. The project encompasses two genetically related deposits: the polymetallic VMS-style Commonwealth Main and South deposits, and the epithermal stockwork vein system at Silica Hill, known for high-grade silver mineralisation. Kuniko’s work builds on a substantial historical dataset from Impact Minerals, which reported JORC Inferred Mineral Resource Estimates at both Commonwealth and Silica Hill, though Kuniko has yet to independently verify these figures.

Recent drilling results continue to validate and expand upon these historical resources, with the new high-grade intercepts at Silica Hill representing a material step change in the project’s upside potential. The integration of structural controls, geophysics, and geochemistry is sharpening drill targeting and defining a compelling exploration corridor linking Commonwealth and Silica Hill.

Capital and Exploration Momentum

This discovery comes on the heels of Kuniko’s recent capital raising efforts, including a $3.75 million placement with attached options, which underpins the company’s aggressive exploration strategy. The Phase 1 drilling program, comprising six diamond holes totalling 1,239 metres, has intersected sulphide mineralisation in all holes, confirming a robust mineralised corridor. The upcoming Phase 2 campaign aims to leverage this momentum with more extensive step-out drilling and testing of newly identified targets.

Kuniko’s approach aligns with the broader trend of exploring Tier-1 jurisdictions for polymetallic systems with complex structural controls and vertically zoned mineralisation, a strategy that has yielded significant discoveries globally. The company’s next assay releases and drill results will be closely watched for indications of further bonanza-grade zones and resource growth potential.

Given the complexity and scale of the system, future work will also need to address metallurgical characteristics and economic viability, but the current results have undoubtedly reset expectations for Silica Hill’s potential.

Kuniko’s recent assay results echo earlier successes at the Commonwealth Main Shaft, where high-grade massive sulphides were confirmed, setting the stage for an expanded Phase II program focused on resource growth and new zones. This continuity of strong results across the project area reinforces the prospectivity of the Commonwealth–Silica Hill corridor as a significant polymetallic system within the Lachlan Fold Belt. The company’s ongoing integration of geological and geophysical data is expected to refine targeting and enhance discovery potential in upcoming drilling campaigns.
