Cannindah Resources Discovers Major Growth Opportunity in Southern Breccia Zone
Cannindah Resources (ASX: CAE) has identified a compelling opportunity to significantly expand its 14.5 million tonne copper-gold resource at the Cannindah Breccia. Furthermore, drilling is set to commence imminently targeting a 270-metre "Gap Zone" in the southern portion of the deposit. The company's latest analysis reveals that despite representing nearly 50% of the total breccia strike length, the southern portion contains only 22% of the total copper equivalent tonnes in the mineral resource.
This disparity suggests substantial upside potential for Cannindah Resources gap zone exploration activities. Recent drilling results have demonstrated exceptional grades bookending this target zone, including 120 metres at 1.16% copper equivalent from 30m depth and 278 metres at 1.16% copper equivalent from surface, validating the continuity of high-grade mineralisation across the broader deposit footprint.

Strategic Target: The Southern "Gap Zone"
The identified target area spans approximately 270 metres of the 600-metre total resource strike length, where drilling density remains significantly lower compared to the well-defined northern portion. In addition, this presents a unique opportunity to potentially upgrade an already substantial resource through targeted infill drilling.
Key Target Metrics:
| Zone | Strike Length | Resource Share | Drilling Density |
|---|---|---|---|
| Southern Portion | ~300m (50%) | 22% of CuEq tonnes | Significantly lower |
| Northern Portion | ~300m (50%) | 78% of CuEq tonnes | High density |
The contrast is particularly striking when examining copper distribution patterns. In high drill-density areas like the northern extent, copper distribution displays excellent continuity at the 1% copper isosurface (a geological boundary showing where copper grades exceed 1%).
However, in the southern extent where drill data density is lower, this continuity appears less developed—not due to geological differences, but simply due to insufficient drilling coverage. This Cannindah Resources gap zone exploration programme represents a systematic approach to resource expansion rather than speculative exploration.
Drilling Programme Details
The programme targets areas with proven geological continuity but inadequate data coverage:
- 12-hole programme targeting zones of potential high-grade with low drill data density
- Focus on increasing data support for resource interpolation
- Commencement: January 2026
- Additional results pending from 9 holes drilled into the Southern Porphyry Target
Understanding Copper Equivalent: A Key Valuation Metric
Copper equivalent (CuEq) is a standardised metric that combines the value of multiple metals into a single copper-equivalent percentage. For instance, it allows investors to easily compare the total metal value of different intersections or resources.
For Cannindah's calculations, the formula incorporates:
- Copper: Primary metal with 84% recovery
- Gold: Significant credit metal with 65% recovery
- Silver: Additional credit with 65% recovery
- Molybdenum: Minor contributor with 60% recovery
This metric is particularly valuable for polymetallic deposits like Cannindah, where gold and silver credits can significantly enhance the economic value beyond just the copper content. The current 1.09% CuEq average grade compares favourably with many established copper projects globally.
Furthermore, the calculation uses a formula that considers both the metal prices and expected recovery rates during processing. For Cannindah, the pricing assumptions reflect 12-month rolling monthly averages, providing a realistic basis for economic evaluation.
What Makes the Current Resource Foundation So Impressive?
The Mt Cannindah Breccia already hosts an impressive 14.5 million tonne resource at 1.09% copper equivalent. Moreover, it contains substantial quantities of multiple metals:
| Metal | Quantity | Grade |
|---|---|---|
| Copper | 105,000 tonnes | 0.72% |
| Gold | 197,000 ounces | 0.42 g/t |
| Silver | 6.4 million ounces | 13.7 ppm |
The resource is defined within an open pit scenario to 350 metres below surface. However, drilling has demonstrated mineralisation extends to 1,086 metres downhole, indicating substantial depth potential beyond the current resource shell.
Recent drilling has also confirmed high-grade continuity over 140 metres vertical distance from near surface, with intersections extending the mineralised zone an estimated 35-40 metres to the east. These results from the Eastern Extensions programme demonstrate the systematic expansion potential that the Cannindah Resources gap zone exploration programme aims to replicate in the southern portion.
Geological Context and Mineralisation
The Mt Cannindah Breccia is a 600m by 100m zone of fractured brecciated material located on a major north-northeast trending fault contact. This fault lies between an intrusive diorite (a type of igneous rock) and hornfelsed metasedimentary rocks (metamorphosed sedimentary rocks).
This geological setting creates ideal conditions for copper-gold mineralisation. A breccia is a rock composed of angular fragments that have been naturally cemented together.
In mining contexts, breccia zones often host significant mineralisation because the fractured nature of the rock allows mineral-rich fluids to circulate and deposit metals. The geological model indicates that high-grade mineralisation extends beyond the current resource boundaries, particularly in areas where drilling coverage has been limited.
This is what makes the southern Gap Zone such an attractive target for resource expansion in the Cannindah Resources gap zone exploration programme.
Upcoming Catalysts and Timeline
The immediate focus centres on the 12-hole drilling programme commencing this month, specifically designed to test areas with established high-grade potential but insufficient drill data density. Furthermore, this systematic approach could potentially transform the resource distribution and upgrade significant portions of the southern zone.
Near-term Milestones:
- January 2026: Commencement of 12-hole Gap Zone drilling programme
- Imminent: Assay results from 9 holes drilled into Southern Porphyry Target
- 2026: Potential resource upgrade following successful drilling campaign
The timing of this Cannindah Resources gap zone exploration programme coincides with elevated copper prices and increasing global demand for copper. This demand is driven by electrification trends and renewable energy infrastructure development.
"The recognition of the drill data density impact on the mineralisation distribution is a unique opportunity to potentially upgrade an already exciting MRE. The contrast between the northern portion and the southern portion is striking. This drill programme has the potential to once again upgrade the Cannindah Project." – Cameron Switzer, Managing Director and CEO
Investment Thesis: Unlocking Hidden Value
Cannindah presents a compelling value proposition through its systematic approach to resource expansion. The company has identified a clear geological and technical opportunity where limited historical drilling has potentially masked the true extent of high-grade mineralisation.
Key Investment Drivers:
Proven High-Grade System: Recent results confirm the development of high-grade copper-gold-silver mineralisation extends beyond current resource boundaries. Intersections in previously untested areas validate the broader geological model.
Systematic Expansion Approach: Rather than speculative exploration, Cannindah is targeting areas with established geological continuity but insufficient data density. This represents a lower-risk method of resource growth.
Scale Potential: The southern portion represents 50% of the strike length but only 22% of contained metal, suggesting substantial scope for resource redistribution and potential expansion.
Established Infrastructure Context: The project benefits from existing resource definition work, metallurgical testing, and established mining-friendly jurisdiction positioning.
In addition, the systematic approach demonstrates a methodical strategy that could deliver significant value without the typical risks associated with greenfield exploration.
Technical Analysis: Data Density Impact
The company's analysis reveals that drill data density directly correlates with resource definition quality. In the northern extent where drilling has been comprehensive, copper distribution shows excellent continuity at the 1% copper isosurface.
This contrasts sharply with the southern extent where lower drill data density has resulted in less well-developed continuity mapping.
Resource Distribution Analysis:
| Metric | Northern Portion | Southern Portion |
|---|---|---|
| Strike Length | 300m (50%) | 300m (50%) |
| Resource Contribution | 78% of CuEq tonnes | 22% of CuEq tonnes |
| Drilling Coverage | High density | Significantly lower |
| Grade Continuity | Well established | Under-defined |
This analysis forms the technical foundation for the targeted drilling programme. Furthermore, it suggests that successful completion could substantially redistribute the resource estimate.

Why Should Investors Track Cannindah Resources?
Cannindah Resources has positioned itself for potential significant resource growth through a methodical, data-driven approach to expanding its already substantial copper-gold asset. The company's identification of the "Gap Zone" represents exactly the type of systematic exploration that can unlock hidden value in established projects.
With copper prices remaining elevated due to global electrification trends and supply constraints, companies with substantial, well-defined resources are increasingly valuable. Cannindah's 14.5 million tonne resource provides a solid foundation, whilst the identified expansion potential offers meaningful upside.
The systematic approach reduces execution risk whilst maintaining significant upside potential. Unlike greenfield exploration, the company is targeting areas with established geological continuity and proven mineralisation. These areas simply require additional drilling to improve resource confidence and potentially expand the mineral inventory.
The upcoming drilling programme targeting the 270-metre Gap Zone could potentially redistribute and expand the existing resource. This would transform the project's economics and position Cannindah as a more substantial player in the Australian copper sector.
Cannindah Resources has identified a systematic opportunity to potentially upgrade its substantial copper-gold resource through targeted drilling in under-explored areas. With drilling commencing imminently and additional results pending, the next few months could prove transformational for the company's asset base and investment thesis.
