Phase 2 drilling complete as Kuniko advances Commonwealth-Silica Hill towards MRE update

Kuniko Limited (ASX: KNI) has completed its Phase 2 diamond drilling program at the Silica Hill prospect, with five holes drilled for a total of 1,492.4 metres. The program builds on Phase 1 results and extends the geological understanding of the mineralised system, including deeper testing beyond much of the historical drilling.

Phase 1 drilling results at Commonwealth-Silica Hill established the high-grade intercepts that gave Kuniko the confidence to design and fund the Phase 2 program, with multiple holes returning elevated silver and gold values across both the Northern and Southern Lodes.

Since acquiring its interest in the Commonwealth Project in October 2025, Kuniko has now drilled 11 diamond holes for a combined 2,731 metres at Commonwealth-Silica Hill. With Phase 2 complete and assays expected in October 2026, the company is targeting an updated Mineral Resource Estimate (MRE) for Q4 2026.

Managing Director Maja McGuire

“Completing Phase 2 drilling is an important milestone for Kuniko, with 11 diamond holes now completed for 2,731 metres across the Commonwealth–Silica Hill system. The program has significantly advanced our understanding of the mineralised system, with assays expected in October and planned DHEM surveys to provide further insight into potential extensions.

Our immediate focus is on integrating these results and progressing an updated MRE in Q4 2026. At the same time, we are advancing a pipeline of regional targets across the broader district-scale system. With land access in place and permitting underway, we are progressing those targets towards drilling as we test the wider discovery potential of Commonwealth–Silica Hill.”

Q4 2026 MRE update: what’s coming next

The pathway from here to a resource update follows a clear, defined sequence. Investors watching for the near-term catalyst should understand what sits between now and the Q4 2026 MRE.

Pathway to the Q4 2026 Mineral Resource Estimate

  1. Core processing and sampling nearing completion, with Phase 2 assay results expected October 2026
  2. Downhole electromagnetic (DHEM) surveying of selected PVC-cased Phase 2 holes to identify conductive responses associated with sulphide mineralisation — testing for deeper off-hole conductors and potential extensions to the Northern and Southern Lodes
  3. Results integrated with drilling, geological and assay data to refine the three-dimensional interpretation of the Silica Hill mineralised system
  4. Updated MRE incorporating Phase 1 and Phase 2 results, targeted for Q4 2026

The DHEM program adds meaningful optionality to the near-term story. Prior DHEM surveying at Silica Hill — completed historically by Impact Minerals — identified discrete conductive plates associated with the interpreted mineralised system, demonstrating the technique as a reliable vector towards sulphide mineralisation. Kuniko’s Phase 2 holes extend significantly deeper than much of that historical drilling, which means the upcoming surveys have the opportunity to test for conductors at depths that were previously untested.

Any off-hole conductors identified could expand the known mineralised footprint before the resource is updated — a meaningful upside scenario to hold alongside the base-case MRE timeline.

Understanding the Commonwealth-Silica Hill system

For investors less familiar with NSW exploration geology, understanding why this project sits where it does matters for context.

A Tier-1 address in NSW’s gold and silver belt

The Commonwealth Project is located approximately 100km north of Orange, New South Wales, within the Lachlan Fold Belt. This is one of Australia’s most proven base and precious metals regions, hosting major operations including Cadia-Ridgeway (owned by Newmont), Northparkes and Cowal (both owned by Evolution Mining). The project sits along trend from Alkane Resources’ Boda-Kaiser porphyry copper-gold deposit, which contains over 10 million ounces of gold equivalent.

That address matters because it places Commonwealth-Silica Hill within a geological corridor that has already produced world-class mines.

Two related deposits, one growing dataset

The Commonwealth Project comprises two genetically related deposits sitting within 200 metres of each other. They share a mineralised system but exhibit distinct styles of mineralisation.

Deposit Style Key Metals Status
Commonwealth Main & Commonwealth South Polymetallic VMS-style High-grade gold, silver, zinc Prior JORC (2012) Inferred MRE reported by Impact Minerals — not independently verified or adopted by Kuniko
Silica Hill Epithermal stockwork vein system High-grade silver with silver sulphosalts Prior JORC (2012) Inferred MRE reported by Impact Minerals — not independently verified or adopted by Kuniko

It is worth noting clearly that while Impact Minerals previously reported JORC (2012) Inferred MRE estimates at both Commonwealth and Silica Hill, Kuniko has not independently verified or adopted these estimates. They should not be relied upon as Kuniko’s own figures. The updated MRE Kuniko is targeting for Q4 2026 will incorporate the company’s own Phase 1 and Phase 2 drilling data.

VMS stands for volcanogenic massive sulphide — a deposit type where metals precipitate from hydrothermal fluids on or near the seafloor, often forming concentrated sulphide lenses. Epithermal systems are shallower, lower-temperature deposits associated with volcanic activity, typically hosting precious metals in veins or stockworks.

District-scale potential keeps the exploration story open

The immediate focus is the MRE update, but the broader Commonwealth-Silica Hill district carries a longer exploration runway that gives the investment thesis additional depth.

Kuniko is advancing regional targets across the district in parallel with the resource work. Land access is in place and permitting is underway, with priority targets being progressed towards future drilling. A previously reported integrated geophysical review (announced 20 August 2026) identified a prominent magnetic intrusive complex southeast of Silica Hill, coincident with gravity, IP and MobileMT anomalies. This is interpreted as a potential buried intrusive system and provides a target for porphyry-style mineralisation.

Untested regional prospects being advanced include:

  • Silica Hill East
  • Geenobbys
  • Gladstone
  • Welcome Jack trend

The MRE update is the catalyst on the immediate horizon. The district-scale pipeline is what sits behind it — a set of additional targets that, if systematically tested, could extend the exploration story well beyond the current Silica Hill system.

For investors exploring the regional pipeline in more depth, our full explainer on the district-scale geophysical review covers the integrated gravity, IP and MobileMT findings that identified the magnetic intrusive complex southeast of Silica Hill, including the interpreted target geometry and what a porphyry-style system at that location would mean for the broader project.

Frequently Asked Questions

What is a Mineral Resource Estimate and why does it matter for Kuniko?

A Mineral Resource Estimate (MRE) is a formal, JORC-compliant calculation of the quantity and grade of mineralisation within a deposit, providing the foundation for assessing a project's economic potential. For Kuniko, the Q4 2026 MRE update will be the first resource estimate incorporating the company's own Phase 1 and Phase 2 drilling data at Commonwealth-Silica Hill, replacing historical estimates that Kuniko has not independently verified.

What are DHEM surveys and what could they reveal at Silica Hill?

Downhole electromagnetic (DHEM) surveys measure conductive responses in rock surrounding a drillhole, helping identify sulphide mineralisation that the drill bit may have missed — known as off-hole conductors. At Silica Hill, prior DHEM work by Impact Minerals already identified conductive plates linked to the mineralised system, and Kuniko's Phase 2 holes extend deeper than that historical drilling, meaning the upcoming surveys could identify mineralisation at previously untested depths.

When will Kuniko release Phase 2 assay results from Commonwealth-Silica Hill?

Kuniko expects Phase 2 assay results in October 2026, following completion of core processing and sampling. These results will be integrated with Phase 1 data to support an updated Mineral Resource Estimate targeted for Q4 2026.

What is the geological significance of the Lachlan Fold Belt for the Commonwealth Project?

The Lachlan Fold Belt is one of Australia's most productive base and precious metals regions, hosting major operations including Newmont's Cadia-Ridgeway, Evolution Mining's Northparkes and Cowal, and Alkane Resources' Boda-Kaiser deposit with over 10 million ounces of gold equivalent. Kuniko's Commonwealth Project sits within this corridor approximately 100km north of Orange, NSW, placing it in a proven geological address for significant mineralisation.

What regional exploration targets is Kuniko advancing beyond Silica Hill?

Kuniko is advancing four untested regional prospects — Silica Hill East, Geenobbys, Gladstone, and Welcome Jack — towards future drilling, with land access in place and permitting underway. A geophysical review announced in August 2026 also identified a potential buried intrusive system southeast of Silica Hill, interpreted as a porphyry-style target based on coincident gravity, IP, and MobileMT anomalies.
