Kuniko Eyes December 2026 Resource Upgrade as Silica Hill Drill Results Impress
Key Takeaways
- Kuniko's December 2026 MRE upgrade is underpinned by three drill holes at Silica Hill that all sit outside the existing mineralised block model, meaning the upgrade represents a genuine resource expansion rather than a routine revision.
- The headline intercept from CMKNI004 — 84m at 2.6 g/t AuEq, including 0.5m at 347 g/t AuEq — is the only hole drilled into the Silica Hill discovery zone, with Phase 2 follow-up assays due for announcement in October 2026.
- At a market cap of just $7.9 million and proforma cash of $2.5 million, Kuniko is priced with almost no value assigned to a high-grade gold-silver system in the same Lachlan Fold Belt as Newmont's 40Moz Cadia deposit.
- The Welcome Jack Corridor adds 2km of historically under-drilled strike on the same fault structure as the Walls and Stringers mines, with Stringers never having been drilled and regional drilling planning scheduled for October 2026.
- The 575km² tenement package hosts both a polymetallic VMS system and an epithermal stockwork vein system, providing multiple independent geological pathways to resource growth beyond the current MRE upgrade target.
Commonwealth–Silica Hill Project: Kuniko builds toward December 2026 MRE upgrade
In its September 2026 investor presentation, Kuniko Limited (ASX: KNI) outlined the strategic case for its Commonwealth–Silica Hill Project in New South Wales, a high-grade gold-silver system spanning approximately 5km² within Australia’s Lachlan Fold Belt. The near-term focus is clear: a Mineral Resource Estimate (MRE) upgrade scheduled for December 2026, underpinned by an active Phase 2 drilling campaign producing compelling intercepts.
Key corporate details from the presentation:
- Share price: A$0.031 (1 September 2026)
- Market cap: A$7.9m
- Proforma cash: A$2.5m
- Proforma shares on issue: 254.3m (assumes completion of both tranches of the $1.3m capital raise announced 4 August 2026)

High-grade results that define the opportunity
Silica Hill: a new discovery taking shape
The Silica Hill discovery sits approximately 100m beyond the existing mineralisation at Commonwealth Main, with the zone remaining open up-dip, down-dip, and along strike. The first and only hole drilled into the new discovery zone, CMKNI004, returned headline intercepts that management presented as central to the MRE upgrade thesis:
The Phase 1 drilling program at Commonwealth-Silica Hill established the geological foundation for the current work, with the high-grade intercepts from that campaign providing the data set that justified the expanded Phase 2 scope now targeting the MRE upgrade.
- 84m @ 2.6 g/t AuEq from 226m
- Including 3.4m @ 50 g/t AuEq from 227.5m (4.1 g/t Au, 2,947 g/t Ag)
- Including 0.5m @ 347 g/t AuEq (20,603 g/t Ag, 27 g/t Au)
Phase 2 drilling has since extended the mineralised system by a further 100m, with Hole 7 drilled approximately 60m down-dip and Hole 8 approximately 40m up-dip of the prior intersection. Critically, all three holes into the new discovery zone sit outside the existing mineralised block model, directly supporting the case for a grade and tonnage upgrade at the December 2026 MRE.
Welcome Jack Corridor adds strike length
The presentation highlighted the Welcome Jack Corridor as a near-term expansion target with 2km of strike length that has historically been under-drilled due to a lack of capital. Shallow historical drilling returned encouraging results:
- CMIPT053: 2m @ 5.7 g/t Au, including 1m @ 8.0 g/t Au (from 29m depth)
- CMIPT027: 20m @ 0.5 g/t Au & 27 g/t Ag, including 1m @ 2.9 g/t Au & 144 g/t Ag (from 55m depth)
The Walls and Stringers mines sit approximately 800m from the Welcome Jack Prospect on the same fault structure, with Walls having seen one drill hole and Stringers having never been drilled.
What are VMS and epithermal gold-silver systems?
The Commonwealth–Silica Hill Project hosts two distinct geological systems, and understanding the difference matters for assessing the project’s scale potential.
At Commonwealth Main and Commonwealth South, mineralisation is classified as a polymetallic VMS system. VMS stands for volcanogenic massive sulphide, a deposit type formed on ancient seafloors where volcanic fluids deposit concentrated metals including gold, silver, zinc, lead, and copper together. These systems are globally significant precisely because of their multi-metal character.
Drill results confirming massive sulphide continuity across the Commonwealth Main system have been a key input to the geological confidence underpinning the December 2026 MRE upgrade, with consistent grade and width demonstrated across multiple holes in the VMS horizon.
Silica Hill represents something different: an epithermal stockwork vein system, where gold and silver are deposited closer to the surface through hydrothermal fluids in fracture networks. The presentation noted that the broader system may be potentially linked to a deeper porphyry copper-gold source immediately adjacent to the Alkane Boda-Kaiser porphyry deposit, though Kuniko has not independently validated this interpretation.
For investors, the practical implication is that the 575km² land package hosts multiple mineralisation styles, providing several independent pathways to resource growth rather than relying on a single geological model.

The path to December 2026 and beyond
The presentation outlined a three-phase growth roadmap:
- Current: Grow and validate the existing resource through the MRE upgrade targeted for December 2026
- Near term: Expand the mineralised footprint through the Silica Hill 500m extension and the Welcome Jack Corridor
- Medium term: Systematically test four additional priority discovery centres across the approximately 5km² project area
The key workstream timeline presented was:
| Workstream | September | October | November | December |
|---|---|---|---|---|
| Phase 2 Drilling | Phase 2 drilling program | Assays announced | ||
| Regional Drilling | Exploration targets identified | Regional drilling planning & preparation | Regional drilling assessment | |
| MRE Upgrade | Data compilation | Resource modelling | Resource estimation & MRE Upgrade |
Land access is secured and drill permitting is underway. All priority targets sit within 1km of the existing resource, which the presentation highlighted as a meaningful de-risking factor for the exploration programme.
The Lachlan Fold Belt context frames the district pedigree. Kuniko’s neighbours in the belt include Newmont’s Cadia at 40Moz Au, Evolution’s Cowal at more than 14Moz Au, and the Boda-Kaiser discovery at 8.3Moz Au and 1.5Mt Cu. The presentation cited these neighbours to illustrate the quality of the geological address, not to imply that Kuniko’s project is equivalent in scale.
