Litchfield Minerals VT1 Conductor Discovery Exceeds Initial Expectations

Litchfield Minerals (ASX: LMS) has provided a compelling technical update on its VT1 Conductor at the Oonagalabi Project in the Northern Territory, revealing a far more substantial and complex electromagnetic system than initially anticipated. The Litchfield Minerals VT1 Conductor Discovery represents one of the most significant exploration developments in the region, with latest Downhole Electromagnetic (DHEM) surveys revealing a 995 Siemens conductor strength – significantly higher than the 700 Siemens previously indicated by airborne surveys.

Litchfield Minerals Reveals Significantly Larger VT1 Conductor System With Multi-Plate Complexity

The DHEM data confirms that recent drill hole OGRC0012 missed the main conductive body by approximately 75 metres, yet still intersected mineralised sulphides that demonstrate the presence of a fertile system. This discovery validates the company's geological model while highlighting the scale of the untested conductor system that extends across a 400-metre folded corridor containing six to seven overlapping, high-conductance plates.

Furthermore, the technical findings demonstrate that the Litchfield Minerals VT1 Conductor Discovery extends far beyond initial expectations. The system's complexity indicates multiple geological events that have concentrated metals over time, potentially creating a large-scale mineralised system.

Managing Director's Comment:
"VT1 continues to grow in size, strength and significance. Our geophysicists are confident we're dealing with a very strong, multi-plate conductor system, one that's considerably larger and more complex than what the airborne data initially suggested. Everything we're seeing, from the sulphides in drilling to the EM response and now the surface geochemistry, reinforces our belief that VT1 sits within a large, fertile mineralising system."

Key Technical Findings

Understanding Electromagnetic Conductors: Why This Discovery Matters

Electromagnetic (EM) conductors represent zones where electrical current flows easily through rock formations, typically indicating the presence of metallic sulphide minerals. In mineral exploration, strong conductors like VT1's 995 Siemens reading suggest substantial concentrations of conductive minerals such as copper, nickel, and other base metals.

Why Investors Should Care About Conductor Strength:

• Higher Siemens readings indicate denser mineral concentrations
• Multi-plate systems suggest repeated mineralisation events
• Strong near-surface conductors are typically more economical to extract
• The 400-metre corridor scale suggests potential for a significant deposit

The DHEM technique provides precision targeting within 100-150 metres, allowing geologists to map conductor geometry with exceptional accuracy before committing to expensive drilling programmes. Moreover, the multi-plate configuration demonstrates that the Litchfield Minerals VT1 Conductor Discovery represents multiple geological events that have concentrated metals over time.

Palladium Discovery Adds Magmatic Dimension to VT1 System

Recent laboratory assays from surface rock chip sample RK0072 have returned highly anomalous Platinum Group Element (PGE) results, including 0.1 g/t Palladium and elevated 850ppm Nickel values. While these grades may appear modest, they are considered highly anomalous in surface weathered materials and point to a potential magmatic-hydrothermal source system.

Consequently, these results add another dimension to the discovery, suggesting the presence of precious metals alongside base metal mineralisation. In addition, the palladium presence indicates potential for high-value minerals within the conductor system.

Geochemical Results Summary

The combination of base metals, precious metals, and PGEs suggests a multi-style mineralisation system with potential for multiple ore types within the same geological setting. This diversity typically indicates robust, long-lived hydrothermal systems capable of producing large-scale deposits.

Purpose-Built Ground EM Programme Launches Mid-November

Litchfield has designed a high-precision Ground EM survey specifically optimised for VT1's anticipated strong electromagnetic response. The programme commences in the second half of November 2025 with several key technical advantages.

However, this survey differs from conventional approaches by incorporating lessons learned from the Litchfield Minerals VT1 Conductor Discovery's unique characteristics. The programme will utilise specialised parameters designed to capture the full system geometry.

Survey Design Features:

• Tighter line spacing and higher station density to resolve multiple overlapping plates
• Fixed-loop EM configuration across DHEM-defined areas for maximum spatial control
• Optimised parameters prioritising data density over repeat measurements
• Near-DHEM resolution across the entire surface area

This purpose-built approach will deliver comprehensive conductor mapping across the 400-metre corridor, allowing the company to drill with maximum confidence immediately following data interpretation. The survey design recognises that VT1's exceptional conductor strength requires specialised parameters to capture the full system geometry.

Investment Thesis: Multi-Commodity Discovery Potential in Proven Geological Terrane

The discovery represents a compelling investment opportunity within Australia's Northern Territory mineral province, an area known for significant base metal discoveries. The conductor system's technical characteristics suggest potential for a substantial mineral deposit with several key investment drivers.
