Litchfield Minerals Confirms Large-Scale Copper-Zinc Discovery at Oonagalabi

Outstanding Drill Results Define Large-Scale System

The copper-zinc discovery by Litchfield Minerals Ltd has delivered exceptional intercepts across multiple holes, with OGRC017 emerging as a standout performer. The Phase 2 RC drilling campaign demonstrates the remarkable potential of this polymetallic system in the Northern Territory.

Key Intercepts from OGRC017:

OGRC016 Results:

• 91m @ 0.60% Cu & 1.00% Zn from 23m
• Including 27m @ 0.55% Cu, 1.33% Zn, 5.3 g/t Ag from 23m
• And 39m @ 0.81% Cu, 1.09% Zn, 5.8 g/t Ag from 75m

These results demonstrate the critical characteristic of broad mineralised envelopes hosting multiple higher-grade internal zones – exactly what geologists expect to see in large polymetallic systems with genuine scale potential.

Furthermore, the drilling programme has successfully validated the company's geological thesis, delivering multiple thick, stacked mineralised zones that demonstrate genuine systematic continuity from near surface. These results significantly de-risk the project from a geological perspective while opening up numerous pathways for expanding both scale and grade through ongoing exploration.

Managing Director's Perspective:

"These results from Oonagalabi reinforce our conviction that we are dealing with a large, robust copper–zinc system with genuine scale. Intercepts such as 161 metres of continuous mineralisation from near surface, containing multiple higher-grade internal zones, demonstrate both the thickness and continuity of the system."

Understanding Polymetallic Systems: What Makes Oonagalabi Special

Polymetallic systems are mineral deposits containing multiple valuable metals – in this case, copper, zinc, and silver. These systems form when hot, metal-rich fluids move through rock formations, depositing minerals in layers or zones over geological time.

What makes the copper-zinc discovery by Litchfield Minerals Ltd particularly attractive is its stacked mineralised horizons – multiple metal-bearing layers positioned on top of each other. This geological architecture suggests several advantages for mineral exploration:

1. Systematic mineralisation rather than isolated pockets
2. Multiple exploration targets within a single system
3. Potential for resource growth through step-out drilling
4. Operational advantages from concentrated mineralisation

For investors, this means Litchfield isn't chasing scattered mineralisation across vast areas, but rather defining what appears to be a coherent, large-scale system with multiple pathways to grow resources. However, the complexity of such systems requires advanced drilling techniques to fully understand their geometry and potential.

Strategic Drilling Approach Maximises Discovery Potential

Litchfield's systematic drilling strategy demonstrates sophisticated technical thinking designed to maximise shareholder value. Rather than targeting isolated high-grade zones early in the programme, the company is deliberately mapping the outer boundaries of the mineralised system first.

Phase-by-Phase Strategy:

1. Current Focus: Define the lateral and vertical extent of thick mineralised packages
2. Next Phase: Step out 100m minimum intervals to find system boundaries
3. Future Phases: Work progressively back toward system centre where highest grades are expected

This approach ensures the company first establishes scale and continuity before optimising for grade – a methodology that typically delivers superior resource estimation outcomes and reduces geological risk. In addition, this systematic approach allows for better understanding of the deposit's overall architecture.

Immediate Targets Include:

• Diamond drilling to test strong magnetic anomaly within main zone
• Step-out drilling to the Northeast (500m from current drilling)
• System extension to Southwest (1km from current drilling)
• Down-dip extensions across the site

VT2 Discovery Validates Geophysical Targeting

The VT2 target has confirmed a large blind sulphide system coincident with VTEM and DHEM conductors, validating the company's geophysical survey interpretation capabilities. While grades intersected to date are below ultimate targets, the presence of widespread sulphides carrying base-metal tenor represents a critical technical milestone.

VT2 Significance:

• 34m @ 0.17% Cu and 0.78% Zn from 190m depth
• Confirms preserved sulphide body at depth
• Sulphide assemblage includes pyrrhotite, sphalerite, and chalcopyrite
• Zinc values up to 7% and copper values up to 1.2% encountered

The geological interpretation suggests VT2 represents a sulphide halo surrounding potentially higher-grade feeder zones – a common characteristic of large polymetallic systems. Consequently, the company plans to use deeper-seeking geophysics and structural interpretation to vector toward these higher-grade accumulation zones.

Upcoming Catalysts and Expansion Plans

Litchfield has outlined an aggressive exploration timeline designed to maintain strong news flow throughout 2026. The copper-zinc discovery by Litchfield Minerals Ltd continues to expand with each drilling programme, creating multiple opportunities for investors to track progress.

Near-Term Milestones:

The company benefits from BHP's technical input through their partnership, providing access to world-class expertise in large-scale mineral system evaluation. Furthermore, this collaboration enhances the technical rigour applied to copper exploration across the project.

Growth Potential Indicators:

• Mineralisation remains open along strike and down-dip
• Multiple priority targets identified but undrilled
• Large areas of favourable geology completely untested
• System extends over multiple kilometres of prospective ground

Investment Thesis: Scale Meets Systematic Approach

Litchfield Minerals has positioned itself at the intersection of discovery potential and systematic execution – a combination that historically generates superior investor returns in the exploration sector. The copper-zinc discovery by Litchfield Minerals Ltd represents a compelling investment opportunity in the base metals space.

Key Investment Differentiators:

1. Proven System Scale: 161m continuous mineralisation from near-surface
2. Multiple Metal Credits: Copper, zinc, and silver provide revenue diversification
3. Systematic Approach: Methodical drilling designed to optimise resource outcomes
4. Strategic Partnership: BHP technical input accelerates discovery potential
5. Extensive Land Position: Large tenement package with multiple undrilled targets

The company's two-fold exploration strategy – completing deep-seeking geophysics for broader system assessment while advancing the established Oonagalabi Main Zone – provides both near-term development potential and longer-term discovery upside. For instance, this approach allows for zinc exploration to progress alongside copper targeting.

Financial Considerations:

• Diamond drilling averaging 25m per shift (in line with expectations)
• Multiple drilling rigs mobilised for continuous exploration
• Strong technical team with systematic approach to resource definition

Why Investors Should Follow Litchfield Minerals

The combination of exceptional intercept lengths, systematic mineralisation, and methodical exploration strategy positions Litchfield as one of the most compelling copper-zinc stories in the Australian market. Moreover, the company's approach to Northern Territory mining demonstrates best practices in exploration methodology.

Compelling Tracking Reasons:

• Scale Validation: 161m mineralised intercepts demonstrate genuine system scale
• Continuity Proven: Multiple holes confirm lateral and vertical mineralisation continuity
• Growth Pipeline: Large undrilled target areas provide multiple expansion pathways
• Technical Excellence: Strategic drilling approach maximises discovery probability
• Partnership Advantage: BHP technical input accelerates system understanding

With mineralisation remaining open in all directions, multiple high-priority targets undrilled, and a systematic approach designed to unlock both scale and grade, Litchfield offers investors exposure to what could develop into a significant polymetallic discovery. However, investors should consider the broader context of ASX mining stocks when evaluating this opportunity.

Key Takeaway:

Litchfield Minerals has validated a large-scale copper-zinc system at Oonagalabi with exceptional continuity and multiple growth pathways. The systematic drilling approach, combined with BHP's technical expertise and extensive undrilled targets, positions the company for continued value creation throughout 2026 and beyond.
