AusQuest Prepares Major Expansion Drilling at Promising Cangallo Copper-Gold Discovery
The Ausquest Cangallo drilling program represents a pivotal moment for AusQuest Limited (ASX: AQD) as the company advances its 100% owned Cangallo Porphyry Copper-Gold project in Peru. This ambitious 6,000+ metre drilling programme is set to commence imminently, targeting what geological indicators suggest could be the high-grade core of this emerging porphyry system.
The upcoming programme comprises 14 drill holes across 6,000+ metres and is designed to expand the known copper and gold mineralisation southward by potentially 1,000 metres. This expansion could effectively double the resource potential of the current discovery.
Surface sampling in target areas has returned highly anomalous results including +0.5% copper, +1.0g/t gold, and +20ppm molybdenum. These results serve as critical indicators of porphyry system intensity.
Key Investment Highlight:
The Stage 3 drilling programme could potentially double the size of the resource by extending mineralisation a further 1,000 metres south of current drill coverage.
Understanding Porphyry Copper Systems: The Foundation of Major Mining Operations
For investors new to mining exploration, understanding porphyry copper systems is crucial to appreciating AusQuest's opportunity at Cangallo. A porphyry system forms when copper-rich magma intrudes into existing rock, creating a large, low-to-moderate grade deposit that can span several kilometres.
Why Porphyry Systems Matter to Investors:
- They typically contain massive tonnages of copper and gold
- The centre or core of these systems often hosts the highest grades
- Some of the world's largest copper mines are porphyry deposits
- They provide long-life, scalable mining operations
Furthermore, these systems offer significant economic advantages due to their size and predictable geology. The scale of porphyry deposits often justifies large-scale mining operations.
Key Geological Indicators at Cangallo:
- Sericite alteration – indicates proximity to mineralised core
- Magnetite destruction – suggests intense alteration from copper-bearing fluids
- Multi-element geochemistry – copper, gold, and molybdenum together signal porphyry potential
The geological evidence consistently points south of AusQuest's current drilling as the likely location of Cangallo's high-grade core. Consequently, the Ausquest Cangallo drilling program has been specifically designed to test this hypothesis.
Strategic Drilling Programme Targets High-Grade Core
| Programme Details | Stage 3 Specifications |
|---|---|
| Total Metres | 6,000+ metres |
| Number of Holes | ~14 holes |
| Drill Spacing | 300m intervals on 300m apart traverses |
| Target Depth | ~400m down-hole |
| Timeline | 4-6 weeks drilling + 4 weeks for assays |
| Expansion Potential | 1,000m south extension |
The programme utilises systematic grid drilling designed to methodically test the southern extension where multiple geological indicators converge. This systematic approach underpins the Ausquest Cangallo drilling program strategy.
High-Priority Target Indicators:
• Surface geochemistry showing +0.5% Cu and +1.0g/t Au
• Extensive sericite alteration mapping
• Magnetic survey anomalies indicating magnetite destruction
• Molybdenum anomalies (+20ppm) supporting porphyry interpretation
Ground magnetic surveys reveal low magnetic responses in target areas. These responses suggest magnetite destruction typically associated with the intense alteration found at porphyry system centres.
In addition to surface indicators, the drilling programme incorporates lessons learned from previous phases. The spacing and depth targets reflect optimal parameters for porphyry system evaluation.

| Northern mineralisation defined | 1,000m southern extension targeted |
| Surface indicators mapped | High-grade core location identified |
| Porphyry system confirmed | Centre of system to be drill-tested |
Competitive Positioning:
- 100% ownership of the Cangallo project eliminates joint venture complications
- Systematic exploration approach with strong geological foundation
- Experienced management team with proven track record in porphyry exploration
- Strategic location in Peru's established mining jurisdiction
Moreover, the company's focused approach to this single high-quality asset allows for concentrated resources and expertise. This focus contrasts with companies spread across multiple projects.
Technical Strengths:

- Scalable drilling programme designed for resource expansion
- Depth potential with mineralisation extending beyond current drilling
The convergence of anomalous surface geochemistry, alteration mapping, and geophysical targets provides AusQuest with high confidence in the southern extension potential. For instance, the molybdenum anomalies provide additional validation of the porphyry model.
What Makes This Drilling Program Different?
The Ausquest Cangallo drilling program represents a significant step-up from previous exploration phases. Unlike earlier work, this programme specifically targets the interpreted high-grade core of the system.
Previous drilling established the presence of mineralisation but focused on defining the northern extent. However, the Stage 3 programme targets the area with the strongest geological indicators.
The systematic grid pattern ensures comprehensive testing of the target area. Furthermore, the 400-metre depth target provides adequate penetration to test the core of the porphyry system.
Risk Factors to Consider
Whilst the geological case is compelling, investors should consider potential risks:
- Exploration risk – drilling may not intersect expected mineralisation
- Grade continuity – surface results may not reflect subsurface grades
- Metallurgical factors – porphyry deposits can present processing challenges
- Permitting delays – regulatory approvals may extend timelines
Consequently, investors should view this as a high-reward, moderate-risk exploration opportunity. The systematic approach reduces some risks but cannot eliminate exploration uncertainty entirely.
Why Investors Should Track AusQuest's Progress
AusQuest is approaching a potentially transformative period as Stage 3 drilling targets the most prospective area of the Cangallo system. The company's systematic approach has methodically built the geological case for significant resource expansion.
Key Tracking Points:
• Resource expansion confirmation through southern extension drilling
• Grade enhancement potential at the porphyry system core
• Timeline execution with results expected by February 2026
• Geological model validation across the broader Cangallo system
The 1,000-metre southern extension represents substantial upside potential that could double the current resource footprint. With anomalous surface results including +0.5% copper and +1.0g/t gold in target areas, the geological foundation supports management's confidence in this expansion strategy.
