Litchfield Minerals Ltd has unveiled a significant expansion to its exploration efforts at the Oonagalabi Prospect in the Northern Territory. The company is advancing its high-chargeability discovery, which could mark a transformative stage in its exploration pipeline. With robust geophysical survey results, the new findings suggest the presence of a large mineralised system, underscored by intense sulphide mineralisation. This announcement is a compelling development for investors and industry observers alike, signalling both technical and strategic progress.

A Deep Dive into the Oonagalabi Discovery

Litchfield Minerals has long been focused on uncovering the hidden potential of the Northern Territory’s geology. The recent geophysical surveys have revealed a continuous high-chargeability anomaly extending over a strike length of more than 1km, with depths in excess of 500m. Chargeability values in the central core have recorded levels above 40mV/V and even reaching up to 60mV/V, strongly suggesting the presence of intense sulphide mineralisation within the system.

Historically, drilling efforts at Oonagalabi have concentrated on peripheral zones, leaving a significant portion of the high-intensity anomaly untested. The current programme aims to address this gap by targeting the previously unexamined cores directly, potentially unlocking a resource that has been underestimated.

What Are the Key Findings at Oonagalabi?

The announcement has detailed several technical insights which highlight the scale and potential of the discovery:

1. Two parallel sulphide-bearing systems have been identified, each extending over a 1km strike.
2. The core zones exhibit chargeability ranges between 40mV/V and 60mV/V, pointing to zones of elevated mineralisation.
3. Depths exceeding 500m indicate that the anomaly could host a large-scale mineralised system that remains largely untested.
4. A drill-for-equity agreement with Bullion Drilling has been established, ensuring that exploration can proceed with minimal financial strain.
5. Government progress on the Environmental Mining Licence is encouraging, with approvals expected swiftly to enable the commencement of Phase 1 drilling.

These findings provide an invigorating technical foundation for the company’s next exploration steps, reaffirming that the prospect retains significant upside potential.

How Does the Technical Data Enhance the Prospect?

The technical highlights of the Oonagalabi project present a clear roadmap for future exploration, and several data points stand out:

• High Chargeability Peaks: The central anomaly boasts chargeability values exceeding 60mV/V. Such high readings are often directly linked to sulphide-rich rock, a primary indicator of potential mineralisation.
• System Scale: The lateral extent of the high-chargeability zone is significant – over 1km in length – with depths beyond 500m. This scale is indicative of a geologically robust setting that could support sizeable mineral deposits.
• Innovative Drilling Agreement: The drill-for-equity pact with Bullion Drilling is particularly noteworthy. It enables the company to maintain a stronger cash position while leveraging industry expertise to conduct detailed drilling, thereby reducing the overall financial risk.

These technical metrics not only enhance the intrinsic value proposition of the Oonagalabi project but also outline a clear path forward for the testing and possible commercialisation of the discovery.

Why is Induced Polarisation (IP) Critical in This Exploration?

Induced Polarisation (IP) forms a critical part of the exploration techniques applied at Oonagalabi. IP surveys measure the ability of subsurface materials to retain an electrical charge when subjected to an electrical current, a feature that sulphide-rich rocks uniquely demonstrate. The delay in releasing the charge upon termination of the current results in high chargeability values which, when correlated with other geological data, can reveal the presence of economically important mineralisation.

Key Points on the Role of IP:

• IP helps in differentiating between conductive and resistive subsurface materials.
• Higher IP values in the central core hint at the concentration of sulphides, which are often associated with profitable mineral deposits.
• This method allows Litchfield Minerals to focus its drilling on the most prospective zones, thereby reducing exploration risk and optimising resource allocation.

The application of IP thus stands as an excellent example of how advanced geophysical techniques can radically refine exploration strategies and increase the likelihood of a significant discovery.

What Are the Next Steps in the Exploration Campaign?

Litchfield Minerals is poised to transition from the survey phase to actual drilling, a step that investors and market watchers will be keenly observing. The upcoming Phase 1 drilling campaign is set to begin between late March and early April 2025, contingent upon final government licence approvals and detailed planning of geophysical surveys. The key upcoming activities are as follows:

• Ground Gravity Survey: Scheduled for early March 2025, the survey will cover a 3km strike length of the target zone to enhance the geological understanding of the area.
• Phase 1 RC Drilling: Six Reverse Circulation (RC) drilling holes will be completed; five of these will target the western high-chargeability anomalies and one will focus on the eastern anomaly. This strategic approach aims to test the core zones comprehensively.
• Supplementary Geophysical Campaigns: Plans include additional surveys targeting a potential intrusive source located 900m northeast of the main prospect, potentially adding another dimension to the resource model.

This systematic and methodical approach provides robust assurance to stakeholders that every aspect of the discovery is being meticulously evaluated, minimising both financial and operational risks.

What Does This Mean for Investors?

The strategic emphasis on untested high-chargeability zones, combined with efficient resource management, positions Litchfield Minerals as a promising prospect in the competitive Australian exploration landscape. Several key catalysts underscore the investment thesis:

• A large, untested system offers the potential for significant discoveries, promising strong upside should the drilling encounter commercial-grade mineralisation.
• The drill-for-equity arrangement with Bullion Drilling not only de-risks the exploration programme but also ensures that capital is used efficiently.
• Advanced geophysical data, including state-of-the-art IP surveys, bolsters confidence in the geological potential and technical expertise backing the project.
• The company’s proactive approach in obtaining required government approvals and coordinating extensive geophysical studies indicates a well-planned progression from exploration to potential resource development.

Investors Should Note:

• The combination of high chargeability readings and a strategic drilling campaign creates a compelling opportunity.
• The forward-looking approach with staged drilling and geophysical surveys minimises risk while maximising potential return.
• The company's strong cash position, despite a modest market cap, further supports the continuity and financial viability of the exploration programme.

Concluding Thoughts

Litchfield Minerals Ltd is crystallising its position as an agile and innovative player in the Australian exploration sector. By targeting an expansive, high-chargeability system at its Oonagalabi Prospect, the company is setting the stage for what could be a landmark discovery. The integration of sophisticated geophysical methods with an optimised, cash-preserving exploration strategy speaks volumes about the management’s intent to achieve long-term success in a competitive market.

In summary, the Oonagalabi discovery stands as a testament to the hidden geological potential beneath the Northern Territory. With measured yet aggressive exploration plans, investors have a clear view of the catalysts that could translate into significant value. As the project progresses towards its drilling phase, the anticipation grows – not just for new data, but for the possibility of uncovering a resource that could redefine the company’s trajectory.

This announcement, laden with detailed technical insights and forward-thinking exploration strategies, provides a robust narrative that weaves together scientific rigour with strategic anticipation for future growth.
