Litchfield Minerals (ASX: LMS) has delivered another breakthrough at its Oonagalabi Project in the Northern Territory, with drilling confirming massive sulphide mineralisation at the VT2 conductor target. The Litchfield Minerals Oonagalabi discovery news has extended the project's total prospective strike length to over 4 kilometres, establishing one of the most significant emerging copper-zinc systems in Australia's Northern Territory.
VT2 Discovery Validates VTEM Technology Success
Drillhole OGRC011 has proven the effectiveness of Litchfield's geophysical targeting approach, intersecting disseminated to massive sulphides over 111 metres (180-291m depth). The massive sulphide zones contain impressive visual estimates of 10% total sulphides, dominated by chalcopyrite and sphalerite – the key copper and zinc-bearing minerals that drive economic value.
| Key VT2 Discovery Metrics | Value |
|---|---|
| Total sulphide zone | 111m (180-291m) |
| Massive sulphide intervals | 2 zones: 199-204m & 246-256m |
| Visual sulphide content | ~10% average |
| Conductor strike length | >500m |
| VTEM conductor depth | ~150m |
| Conductance rating | Up to 700 Siemens |
The VT2 conductor represents a 500-metre-long geophysical plate at approximately 150 metres depth, with OGRC011 successfully hitting the predicted mineralisation zone. Critically, the hole intersected the lower portion of this massive conductor plate, suggesting significant upside potential remains untested.
Furthermore, this discovery validates the company's systematic exploration methodology across the district-scale system.
Managing Director Matthew Pustahya commented:
"The VT2 intersections mark a major milestone for Litchfield at Oonagalabi… we have now identified two conductors that host meaningful sulphides, with multiple more targets to test. The breadth of targets allows us to be precise."
Understanding VTEM Technology: The Key to Modern Mineral Discovery
Versatile Time Domain Electromagnetic (VTEM) surveying represents cutting-edge geophysical technology that detects conductive bodies underground – typically massive sulphide deposits rich in base metals like copper and zinc.
How VTEM Works for Investors:
- Helicopter-mounted systems transmit electromagnetic pulses into the ground
- Conductive ore bodies generate measurable electromagnetic responses
- Advanced modelling creates 3D plates showing size, depth, and conductance
- Higher conductance readings typically indicate more massive sulphide concentrations
Why This Matters: VTEM technology allows companies to identify drill targets with unprecedented precision, dramatically reducing exploration risk and costs. Litchfield's success rate – hitting significant mineralisation on the first hole at VT2 – demonstrates the technology's power and management's technical expertise.
The 700 Siemens conductance reading at VT1 (the next target) represents exceptionally high values, potentially indicating even more significant mineralisation ahead. In addition, these readings suggest the Oonagalabi system contains substantial base metal endowment potential.
Expanding Mineralisation System Links Bomb Diggity Engine
The VT2 discovery has revealed a different style of mineralisation hosted within mafic intrusive rocks, contrasting with the carbonate-hosted mineralisation at the main Oonagalabi deposit. This discovery supports Litchfield's geological model positioning the Bomb Diggity magnetic anomaly as the thermal engine driving the entire mineralised system.
Confirmed Mafic-Hosted Mineralisation:
- Oonagalabi: OGRC010 (270-280m depth)
- Bomb Diggity: OGRC009 (0-48m depth)
- VT2: OGRC011 (180-291m depth)
The consistent chalcopyrite-sphalerite assemblage across all three locations, combined with the 1-kilometre-long Bomb Diggity intrusion, suggests a large-scale hydrothermal system with significant metal endowment potential. Consequently, this geological understanding provides a framework for targeting additional discoveries across the expanded system.
Strategic Next Steps and Value Catalysts
Litchfield has outlined a systematic approach to value creation across the expanded Oonagalabi system. However, the immediate focus remains on testing the highest-priority conductor targets to maximise discovery potential.
Immediate Catalysts (Next 4-8 weeks):
- Downhole Electromagnetic (DHEM) Survey: Advanced modelling to pinpoint conductor core positions
- VT1 Drilling Commencement: Testing the highest-priority conductor with 400+ metre strike length
- Laboratory Assay Results: Quantitative confirmation of visual sulphide estimates from OGRC011
VT1 Target Advantages:
- 3x higher conductance than VT2 (up to 700 Siemens)
- Surface gossan with confirmed gold, silver, copper, and tellurium mineralisation
- Mapped Oonagalabi Formation at surface – the key host rock for high-grade mineralisation
| Upcoming Milestones | Timeline | Significance |
|---|---|---|
| DHEM survey results | Next week | Refined drilling targets |
| VT1 drilling commencement | Imminent | Test highest-priority conductor |
| OGRC011 assay results | 4 weeks | Quantify copper-zinc grades |
| Additional VTEM targets | Q4 2024 | System expansion potential |
