AusQuest Achieves Major Breakthrough at Cangallo Copper Discovery
AusQuest Limited (ASX: AQD) has delivered exceptional results from its ongoing drilling campaign at the Ausquest Ltd Cangallo copper discovery in Peru, with recent diamond and reverse circulation (RC) drilling substantially expanding the scale and depth of the mineralised system. The latest results demonstrate the growing potential of what could become a transformational copper discovery for the company.

Diamond Drilling Extends System to Over 800m Depth
The recently completed diamond drilling programme has delivered outstanding depth extensions, with two holes totalling 1,630m confirming copper mineralisation extends to depths exceeding 800m. This represents a significant expansion of the known mineralised system and provides compelling evidence of a large-scale porphyry copper deposit.
Furthermore, the depth continuity observed at the Ausquest Ltd Cangallo copper discovery suggests exceptional scale potential for future development phases.
Significant Diamond Drilling Intersections
| Hole | Interval (m) | Copper % | Gold (ppm) | Silver (ppm) |
|---|---|---|---|---|
| CANDD001 | 144m (686-830m EOH) | 0.15% | 0.04 | 0.29 |
| CANDD002 | 78m (546-624m) | 0.17% | 0.04 | 0.33 |
| CANDD002 | 42m (622-664m) | 0.17% | 0.04 | 0.30 |
Higher-grade zones within broader intervals:
- 36m at 0.38% Cu (including 10m at 0.5% Cu)
- 30m at 0.5% Cu and 20m at 0.42% Cu
- Multiple 20m+ intervals above 0.40% Cu
The diamond drilling has confirmed that:
- Copper oxides occur to depths exceeding 300m
- Sulphide mineralisation extends beyond 800m depth
- Supergene enrichment has upgraded copper grades in parts of the system
- Four different mineralised vein sets have been identified, providing vectors to stronger mineralisation zones
RC Drilling Expands Strike Length by 500m
The Stage 3 RC drilling programme has delivered equally impressive results, with six holes completed to date intersecting visual copper oxides and sulphide mineralisation more than 500m south of earlier drilling. This extension increases the total strike length of the mineralised system to over 1.0km from north to south.
In addition, the consistent mineralisation across all RC holes demonstrates the robustness of the Ausquest Ltd Cangallo copper discovery across its expanding footprint.
Visual Mineralisation Summary from RC Drilling
| Hole | Interval (m) | Oxide Minerals | Visual Oxide % | Sulphide Minerals | Visual Sulphide % |
|---|---|---|---|---|---|
| CANRC022 | 215m | Chrysocolla, jarosite | 0.1-0.5% | Pyrite, chalcopyrite | 0.1-0.5% |
| CANRC024 | 70m | Jarosite, neoticite | 0.1% | Pyrite, chalcopyrite | 1% pyrite, 0.5% chalcopyrite |
| CANRC025 | 220m | Neoticite, jarosite | 0.1-0.5% | Pyrite, chalcopyrite, trace bornite | 1% pyrite, 1% chalcopyrite |
| CANRC027 | 255m | Chrysocolla, atacamite, malachite | 0.1-0.5% | Chalcopyrite, pyrite, trace bornite | 1% pyrite, 1% chalcopyrite |
Key Observation: Copper mineralisation occurs consistently across all RC holes, with chalcopyrite, pyrite, and chalcocite being the dominant sulphide minerals, accompanied by malachite, chrysocolla, and atacamite in the oxide zones.
What Makes Porphyry Copper Systems Special?
What is a Porphyry Copper Deposit?
Porphyry copper deposits are among the world's most important sources of copper, typically characterised by:
- Large tonnage: Often exceeding 1 billion tonnes of ore
- Stockwork veining: Networks of small veins containing copper minerals
- Long mine life: Multi-decade operations due to their scale
- Open-pit mining: Generally suitable for low-cost, bulk mining methods
Why Porphyry Systems Matter to Investors:
- Scale potential: Can support major mining operations for decades
- Processing advantages: Oxide zones can be heap-leached, reducing capital costs
- Infrastructure synergies: Large deposits justify significant infrastructure investment
- Global demand: Copper is essential for electrification and renewable energy
The presence of four different mineralised vein sets at the Ausquest Ltd Cangallo copper discovery suggests proximity to the causative intrusive stock. Consequently, this potentially indicates even stronger mineralisation zones nearby.
Strategic Location in Peru's Copper Belt
Cangallo benefits from exceptional location advantages that enhance its development potential:
Location Benefits
- 25km east of Chala town – established infrastructure access
- Within 10km of the coast – proximity to potential port facilities
- Arequipa District location – home to major profitable operations including:
- Cerro Verde
- Cuajone
- Toquepala
- Quellaveco
Competitive Context
| Operation | Head Grade | Mine Life | Status |
|---|---|---|---|
| Cerro Verde | 0.20-0.40% Cu | Multi-decade | Operating |
| Cuajone | 0.20-0.40% Cu | Multi-decade | Operating |
| Toquepala | 0.20-0.40% Cu | Multi-decade | Operating |
| Cangallo | 0.15-0.50% Cu | TBD | Exploration |
The grades being intersected at Cangallo are comparable to producing mines in the district, supporting the potential economic viability of the discovery.
Management Commentary and Forward Outlook
Managing Director Graeme Drew highlighted the significance of the results:
"We are very pleased with what we are seeing in the RC drilling, which is clearly extending the mineralisation a long way to the south, as we expected. Thanks to the recently completed successful placement, we now have sufficient funds to significantly expand our drilling programmes and determine the full potential of this exciting and potentially transformational new copper discovery."
Near-Term Catalysts
January 2026:
- Initial RC assay results from the six completed holes
- Results will guide the next diamond drilling programme
Q1 2026:
- Continuation of RC drilling programme moving further south
- Additional diamond drilling targeting high-grade zones
- Resource estimation work may commence with sufficient drill density
Ongoing:
- Structural interpretation of vein sets to vector toward higher-grade zones
- Metallurgical testing to determine processing characteristics
- Environmental and community engagement for future development phases
However, the most immediate catalyst remains the pending assay results, which will provide crucial data for resource modelling and future drilling decisions.
