Litchfield Minerals Illuminates Massive Sulphide Core at VT2, Plans New Drillhole
Litchfield Minerals’ latest Downhole Electromagnetic survey confirms a large, highly conductive massive sulphide body at the VT2 target, prompting a new high-priority drillhole to test its core.
- DHEM survey validates OGRC011 intersected lower edge of VT2 conductor
- Main conductive core lies up-dip and remains untested
- Conductor extends at least 120m deep and 400m along strike
- New drillhole planned 35m up-dip to target thickest sulphide zone
- Additional IP and ground EM surveys scheduled to refine targets
Confirming a Large-Scale Sulphide System
Litchfield Minerals Limited (ASX, LMS) has delivered a significant update from its Oonagalabi Project in the Northern Territory, revealing that its Downhole Electromagnetic (DHEM) survey has confirmed the presence of a large, conductive massive sulphide body at the VT2 target. The survey, conducted on drillhole OGRC011, shows that while the hole intersected the lower edge of the conductor, the main, thicker core of the sulphide system remains untested and lies directly up-dip.
This discovery is notable for its scale, the VT2 conductor extends at least 120 metres in depth and over 400 metres along strike. The DHEM data could not fully define the limits of the system, suggesting a potentially extensive mineralised zone that aligns with the structurally controlled, copper-zinc rich corridor already known at Oonagalabi.
Strategic Next Steps in Drilling
In response to these findings, Litchfield plans a new drillhole positioned 35 metres up-dip from OGRC011 to directly target the thickest and most conductive part of the sulphide lens. This hole will require a new drill pad due to its location and is scheduled to be drilled during the upcoming Bullion drilling campaign in early November.
Managing Director Matthew Pustahya emphasised the significance of the DHEM results, noting that the initial hole appears to have only grazed the edge of a potentially large and continuous massive sulphide system. The alignment of VTEM, DHEM, and geological data strengthens confidence in the target’s scale and grade potential.
Complementary Geophysical Surveys to Refine Targets
Beyond drilling, Litchfield is advancing its exploration with scheduled Induced Polarisation (IP) and ground electromagnetic (EM) surveys over VT2, VT1, and the broader Oonagalabi-Bomb Diggity corridor. These surveys aim to identify additional sulphide conductors and help vector in on the most prospective zones for follow-up drilling.
The company is also completing its Phase 2 RC drilling program, with seven holes drilled so far. Bullion Drilling, a respected contractor, is set to mobilise in November to continue drilling as new geophysical data becomes available.
Implications for Oonagalabi’s Resource Potential
The confirmation of a large, structurally controlled massive sulphide system at VT2 adds a compelling chapter to Litchfield’s exploration story. The scale and conductivity of the VT2 conductor suggest a significant copper-zinc mineralisation system that could materially enhance the project’s resource base if subsequent drilling confirms economic grades.
While visual estimates from drill core indicate promising sulphide abundance, laboratory assays and further drilling will be essential to quantify the economic potential. The company’s cautious but optimistic approach, combining multiple geophysical techniques with targeted drilling, reflects a methodical strategy to unlock value at Oonagalabi.
Bottom Line?
Litchfield’s confirmation of a large sulphide core at VT2 sets the stage for a pivotal drilling campaign that could reshape the Oonagalabi project’s outlook.
Questions in the middle?
- Will the upcoming drillhole confirm higher-grade massive sulphides at the VT2 core?
- How will IP and ground EM surveys refine the understanding of VT2 and adjacent targets?
- What are the potential resource implications if the conductor extends beyond current survey limits?
