Ausquest Ltd
AusQuest Limited (ASX: AQD) has recommenced drilling at its Cangallo copper-gold discovery in Peru, marking a significant escalation in the company's exploration efforts. The new 6,000+ metre Reverse Circulation (RC) drilling program represents a strategic shift toward testing for higher-grade copper sulphides beneath the already-confirmed oxide mineralisation. The Cangallo drilling plan by Ausquest Ltd demonstrates the company's commitment to unlocking the full potential of this promising discovery.
The timing of this announcement is particularly noteworthy as AusQuest moves from discovery-phase drilling to resource expansion and grade enhancement. With 14-16 drill holes planned across 4-6 weeks, the company is positioning itself to unlock potentially higher-value mineralisation zones that could transform the project's economics.
Key Highlights from the New Drilling Program
The current campaign represents AusQuest's most ambitious drilling effort to date at Cangallo, with several critical objectives defined by the company. Furthermore, this comprehensive drilling strategy aims to systematically evaluate the deposit's potential across multiple dimensions.
• Resource Expansion: Target large-scale copper-gold mineralisation expansion beyond current 1,500m strike length
• Grade Enhancement: Test for higher-grade hypogene copper sulphides beneath oxide zones
• Southern Extension: Initial testing of mineralised system south of current drill coverage
• Processing Suitability: Confirm heap leach amenability of shallow oxide mineralisation
Timeline and Results Expectations:
- RC drilling completion: 4-6 weeks
- Final assay results: ~4 weeks post-completion
- Deep diamond drilling: Commencing immediately after RC completion
- Stage 4 permitting: Final approvals expected Q3 2026
Managing Director Commentary
"We are very excited to have re-commenced drilling at Cangallo, where there is excellent potential to expand the large-scale, widespread copper and gold mineralisation we have defined so far as well as locate higher-grade hypogene copper beneath the oxide resource." – Graeme Drew

What Makes Cangallo a Compelling Discovery
According to company data, the current resource profile demonstrates significant scale potential. In addition, the geological characteristics suggest this discovery could rank amongst Peru's most promising emerging copper projects.
| Dimension | Measurement |
|---|---|
| Strike Length | +1,500m |
| Width | 250-500m |
| Depth | >400m |
| Oxide Zone Depth | 200-250m |
| Mixed Zone Depth | +300m |
Mineralisation Characteristics reported by AusQuest:
- Multiple broad intervals (+150m) grading >0.3% Cu
- High-grade zones containing >0.5% Cu
- Surface-accessible copper oxides described as suitable for heap leach processing
- Transition to mixed oxides and secondary sulphides at depth
- <8km from coast with excellent infrastructure access
Understanding Hypogene Copper Sulphides: The Value Multiplier
Hypogene copper sulphides represent primary mineralisation formed directly from magmatic processes, typically occurring at depth below oxide zones. These sulphide minerals often contain significantly higher copper grades than surface oxides and can dramatically improve project economics. For instance, successful exploration techniques targeting these zones have transformed numerous copper discoveries worldwide.
Key Investment Considerations:
- Higher-grade sulphides could substantially increase resource value
- Sulphide zones often extend to greater depths, expanding resource potential
- Primary mineralisation indicates robust geological controls for sustained grades
- Successful identification could transform Cangallo from bulk tonnage to higher-margin operation
The targeting of hypogene sulphides represents a critical exploration strategy in porphyry copper systems. While oxide zones provide near-surface, lower-grade mineralisation suitable for heap leach processing, the underlying sulphide zones typically host the highest-grade copper mineralisation. This dual-zone approach allows projects to potentially benefit from both low-cost near-surface processing and higher-value deeper mineralisation.
Strategic Drilling Approach: From Discovery to Development
AusQuest's drilling strategy demonstrates a methodical progression from initial discovery to potential resource definition, according to the company's exploration timeline. However, the success of the Cangallo drilling plan by Ausquest Ltd will ultimately depend on the results from these deeper target zones.
Phase Evolution as reported:
- Initial Discovery (2024): Confirmed porphyry copper-gold system
- Resource Expansion (2025): Defined 1,500m+ strike length
- Current Phase (2026): Targeting higher-grade zones and southern extensions
- Upcoming Deep Drilling: Testing hypogene sulphide potential
The phased approach aims to reduce exploration risk while maximising discovery potential. RC drilling provides cost-effective initial testing, with diamond drilling reserved for highest-priority targets identified by RC results.
Why Cangallo Stands Out in Peru's Copper Landscape
Peru ranks as the world's second-largest copper producer, making it an ideal jurisdiction for copper exploration and development. Cangallo's location within 8km of the coast provides exceptional logistics advantages rarely seen in Peruvian copper projects. Consequently, this strategic location positions the project for potentially lower development costs compared to inland discoveries.
Project Advantages reported by AusQuest:
| Factor | Cangallo Benefit |
|---|---|
| Location | Coastal proximity reduces transport costs |
| Processing | Oxide zones suitable for low-cost heap leach |
| Scale | Large-scale system with expansion potential |
| Grade Zones | Emerging higher-grade intervals >0.5% Cu |
| Infrastructure | Excellent access to power, water, and transport |
Market Context:
- Global copper demand driven by electrification and renewable energy
- Peru's established mining jurisdiction with regulatory framework
- Coastal location provides access to international markets
- Heap leach processing offers lower capital and operating costs
The combination of Peru's mining-friendly jurisdiction and Cangallo's coastal proximity creates a compelling investment proposition. Most Peruvian copper projects are located in remote highland areas, requiring significant infrastructure investment. Cangallo's coastal location could potentially reduce both capital and operating costs.
