AusQuest Ltd Cangallo Copper Project Delivers Kilometre-Scale Discovery

Cangallo Breakthrough: 1+ Kilometre Strike Extends Discovery Scale

AusQuest Limited continues to advance exploration activities across its diversified portfolio, with the Ausquest Ltd Cangallo copper project delivering exceptional results during the December 2025 quarterly reporting period. The company's Stage 3 drilling program has dramatically expanded what was already an exciting discovery into a potentially world-class deposit, whilst strong financial backing positions AusQuest for accelerated development.

The standout achievement this quarter was the dramatic expansion of the Cangallo porphyry system through Stage 3 Reverse Circulation drilling. According to the company's quarterly report, the results have fundamentally changed the project's scale and investment proposition:

Key Expansion Metrics:

• Strike length extended over 500 metres south of previous drilling
• Total system now spans more than 1.0 kilometre north-south
• Copper mineralisation confirmed in all new drill holes
• System remains open for further expansion

The expansion represents a critical milestone for porphyry systems, where scale directly correlates with economic viability. Furthermore, major porphyry discoveries typically require extensive strike lengths to achieve the tonnages necessary for world-class status.

Diamond Drilling Confirms Exceptional Depth Potential

While the RC program expanded the system laterally, diamond drilling delivered remarkable depth extensions that demonstrate the robust three-dimensional nature of the mineralisation:

The 555-metre intersection from 5 metres depth in CANDD002 represents one of the most impressive near-surface porphyry intersections reported globally in recent years. In addition, this intersection combines exceptional length with solid grades and critically important shallow depth, suggesting potential for low-cost mining scenarios.

Geological Significance:

• Stockwork vein systems throughout andesitic and dacitic volcanics
• Primary sulphide mineralisation with chlorite-sericite alteration
• Four distinct vein sets providing vectoring opportunities
• Mineralisation extends to over 800 metres depth

Understanding Porphyry Systems: Why Size and Depth Matter

What is a Porphyry Copper System?

Porphyry copper deposits form when magma intrudes into the Earth's crust, creating extensive networks of fractures filled with copper-bearing minerals. These systems are prized by mining companies because they typically contain enormous tonnages of mineralisation that can support large-scale, long-life mining operations.

Key Investment Characteristics:

• Scale: World-class porphyries contain hundreds of millions to billions of tonnes
• Grade continuity: Lower grades but exceptional consistency across vast volumes
• Infrastructure efficiency: Large tonnages support major processing facilities
• Mine life: Typically operate for 20-50+ years

The Ausquest Ltd Cangallo copper project expansion to over 1 kilometre strike length with confirmed depth extensions beyond 800 metres places it firmly within the scale parameters of significant porphyry systems. However, the near-surface nature of high-grade zones could provide early cash flow opportunities whilst deeper zones support long-term production.

Strong Financial Position Funds Aggressive Development

AusQuest strengthened its financial foundation during the quarter with a successful $10 million capital raising that was strongly supported by institutional and sophisticated investors. This funding specifically targets Cangallo expansion and acceleration.

Financial Highlights:

• $9.9 million cash at quarter end
• $10 million raised at $0.047 per share
• 3.2 quarters funding at current spend rates
• Additional South32 funding expected for Australian projects

The placement pricing at $0.047 per share demonstrates strong investor confidence, particularly given the challenging market conditions for junior miners. Consequently, the timing allows AusQuest to capitalise on its discovery momentum without dilution pressure.

Strategic Development Pipeline Across Multiple Jurisdictions

Beyond Cangallo, AusQuest has systematically advanced its diversified portfolio of copper-focused projects across Australia and Peru:

Peru Portfolio Expansion

• Lantana porphyry copper prospect: Final drill approvals expected Q1 2026
• Playa Kali IOCG project: Drill permits imminent for manto-style targets
• Surface easement rights secured for both projects

Australian Assets Under South32 Alliance

The Strategic Alliance Agreement with South32 was extended for two additional years to December 2027, providing continued funding and technical support for Australian exploration:

Balladonia Project (WA):

• Thick intervals with anomalous bismuth (48ppm), molybdenum (46ppm), tellurium (8.9ppm)
• Copper values up to 990ppm in proximity to structural contacts
• Ten additional targets identified for Broken Hill Type mineralisation

Morrisey Magnetite Project (WA):

• Four prospects confirmed producing >70% Fe premium iron product
• Magnetite recoveries averaging 30% at coarse grind size
• Waterfall North intersection of up to 100m thick iron formation

Coober Pedy IOCG Project (SA):

• 13-hole RC program designed for Q2 2026 commencement
• Four prospects targeting gravity/magnetic anomalies near Elizabeth Creek Fault
• Strategic location 100km from Prominent Hill copper-gold deposit

Upcoming Catalysts Present Multiple Re-rating Opportunities

AusQuest has outlined an aggressive development timeline that provides multiple catalysts for investor attention:

Q1 2026 Immediate Catalysts:

1. Stage 3 RC assay results (January-February 2026)
2. Additional South32 funding received for Australian programs
3. Final drill approvals for Lantana and Playa Kali prospects

Q2-Q4 2026 Major Catalysts:

1. Stage 4 drilling commencement at Cangallo (+50,000m program)
2. Resource modelling initiation based on expanded drill database
3. Metallurgical test work for leachability characteristics
4. Australian drilling programs across multiple South32-funded projects

The Stage 4 drilling program represents a potential company-making catalyst, with over 50,000 metres of drilling planned across 20 additional drill pads. For instance, this scale of program could define a maiden resource estimate and attract major mining company interest.
