Litchfield Minerals Confirms High-Grade Mineralisation at Silver Valley Project

Litchfield Minerals Advances Silver Valley Project with Promising Field Results

Litchfield Minerals Limited (ASX: LMS) has successfully completed its first reconnaissance field visit to the Litchfield Minerals Silver Valley project, confirming the presence of significant quartz reef systems with visible sulphide mineralisation across multiple prospects. The work has validated historical high-grade results and positioned the company for immediate advancement to systematic geophysical exploration.

Strong Visual Confirmation Across Four Key Prospects

The exploration team completed field reconnaissance at Silver Valley 1, Silver Valley 2, Silver Valley 3, and Chablo Prospects, observing well-developed quartz reef and vein systems that support the presence of a potentially large, structurally controlled mineralised corridor.

Key field observations included:

• Visible sulphide mineralisation in outcrop, including chalcopyrite and galena
• Multiple vein systems ranging from narrow splays to major reef structures up to 7 metres wide
• Clear strike continuity extending over 200 metres at the main Silver Valley 2 reef
• Historical workings including shafts up to 8 metres deep, indicating previous mining activity

The team collected selective rock chip samples from areas displaying visible copper, lead, and iron mineralisation, with assay results expected in approximately 5 weeks.

Silver Valley 2 Emerges as Standout Target

Silver Valley 2 demonstrated the most impressive scale and exposure, hosting several well-developed quartz reef structures with strong east-west trending reefs and additional north-south trending veins. The prospect features extensive historical workings, including multiple costeans, shafts, and underground development suggesting reef persistence at depth.

Managing Director Matthew Pustahya commented:
"This reconnaissance visit was a success for Litchfield. We were able to get boots-on-ground across Silver Valley 1, 2, 3 and Chablo, and what we saw confirmed the scale and prospectivity of the vein system. Many of the quartz reefs are well developed and we observed clear signs of mineralisation including visible sulphides such as chalcopyrite and galena, which is exactly what we want to see in a system of this style."

Understanding Induced Polarisation Surveys

Gradient Array Induced Polarisation (GAIP) is a geophysical technique that measures the electrical properties of subsurface rocks. When an electrical current is applied to the ground, different rock types respond differently – sulphide minerals create "chargeability" anomalies whilst quartz veins show as "resistivity" anomalies.

For investors, this matters because:
• Cost-effective screening of large areas quickly
• Direct detection of sulphide mineralisation beneath surface cover
• Drill target definition without expensive blind drilling
• Proven effectiveness in similar vein-hosted base metal systems

This technique is particularly valuable at the silver valley exploration because the visible sulphides observed in outcrop confirm that electrical geophysical methods will be highly effective for mapping the system under shallow cover.

Exceptional Historical Results Provide Strong Foundation

The Litchfield Minerals Silver Valley project benefits from a robust database of historical high-grade results that demonstrate the system's economic potential:

These results are particularly significant because they demonstrate:
• Bonanza-grade silver values exceeding 400g/t Ag
• High-grade base metals with lead values up to 25%
• Multi-metal systems carrying copper, lead, silver, and gold
• Consistent mineralisation across multiple prospect areas

Regional Stream Sediment Data Reveals Multi-Kilometre System

Stream sediment sampling has identified a multi-kilometre metal halo with strong coincident gold-silver anomalies across the northern and central Murray Downs Dome. This extensive dispersal train indicates the presence of more than just surface veins and suggests potential for blind mineralised extensions beneath weathered cover.

The regional geochemical footprint significantly expands the exploration target area and supports the interpretation of a large mineralised system with depth extensions masked by regolith cover.

Strategic Next Steps: February Geophysical Programme

Litchfield has contracted Planetary Geophysics to complete a Gradient Array Induced Polarisation survey across Silver Valley 1-3 and Chablo, with fieldwork scheduled for mid-February 2026.

The survey objectives include:
• Rapid screening of large areas for chargeability and resistivity anomalies
• Mapping sulphide mineralisation beneath shallow cover
• Defining drill-ready targets for 2026 field season testing
• Higher-resolution follow-up over priority zones if discrete anomalies are identified

This represents a logical and cost-effective progression from surface reconnaissance to systematic geophysical exploration, designed to rapidly advance the project towards drill testing.

Investment Thesis: High-Grade Base Metal Discovery Potential

Silver Valley represents a compelling exploration opportunity in Australia's Northern Territory, combining multiple factors that enhance silver mining investment appeal:

Proven High-Grade Mineralisation

Historical results demonstrate exceptional grades with bonanza-grade silver values. Furthermore, the presence of multiple prospects with consistent base metal signatures provides strong confidence in the system's economic potential.

Large-Scale System Potential

The multi-kilometre geochemical footprint from stream sediment sampling indicates a structurally controlled corridor with significant discovery upside. In addition, extensive historical workings suggest economic-grade mineralisation was historically mined from the area.

Strategic Location & Infrastructure

Located in the Davenport Province, a proven mineral district, the project benefits from established infrastructure connections. The site sits 170km from Tennant Creek with established mining infrastructure, whilst 100% ownership through subsidiary provides complete operational control.

Systematic Exploration Approach

The company has established an immediate catalyst with geophysical surveys commencing in February. Consequently, there is a clear pathway from geophysics to drill target definition, supported by an experienced team with proven track record in base metal exploration.

Why Should Investors Follow Litchfield Minerals?

The successful Silver Valley reconnaissance has positioned Litchfield as a compelling base metal exploration story with several key advantages:

Near-term Catalysts

Assay results are expected within 5 weeks from reconnaissance sampling. However, the more significant milestone is the geophysical survey commencing mid-February 2026, which should lead to drill target definition by mid-2026.

Technical Merit

Visible sulphide confirmation validates the geophysical approach, whilst historical high-grade results demonstrate economic potential. Furthermore, the large-scale system provides significant discovery upside for patient investors.

Strategic Positioning

The critical minerals focus aligns with global supply chain priorities. Moreover, the Northern Territory location benefits from a mining-friendly jurisdiction, and the systematic exploration approach minimises risk whilst maximising discovery potential.

Key Takeaway:
The Litchfield Minerals Silver Valley project has successfully validated itself as a high-priority exploration target with exceptional historical grades and visible mineralisation across multiple prospects. With systematic geophysical surveys commencing in February, the company is well-positioned to define drill targets and advance towards potential discovery. Investors should monitor progress closely as the project moves from reconnaissance to drill-ready status.

The combination of proven high-grade mineralisation, systematic exploration approach, and immediate upcoming catalysts makes Litchfield Minerals a base metal exploration story worth watching as it advances through 2026.
