Litchfield logs 100m+ copper sulphides in Hole 10 at Oonagalabi; assays rushed and VTEM conductors next
Konrad Forrest

13 October 2025 | Northern Territory – Litchfield Minerals (ASX: LMS) has reported its most significant intersection to date at the Oonagalabi Project, with geological logging and pXRF readings indicating more than 100 metres of copper–zinc sulphide mineralisation in OGRC010 from surface, including multiple broad higher-grade zones.
Highlight intervals (pXRF, preliminary):
• 104m @ 1.37% CuEq from surface (0.92% Cu, 1.59% Zn)
• including 41m @ 1.42% CuEq from surface
• 30m @ 1.02% CuEq from 98m
• 33m @ 1.69% CuEq from 144m, including 21m @ 2.26% CuEq from 144m
The hole targeted the western high-chargeability IP anomaly (+25 mV/V), reinforcing a strong correlation between chargeability and disseminated Cu–Zn sulphides. The folded eastern IP anomaly is interpreted to host similar mineralisation and is slated for drilling later in this Phase 2 program. The company notes that every hole drilled across current and prior programs has intersected copper, highlighting the scale and continuity of the system.
Management comment:
Managing Director Matthew Pustahya said: “Hole 10 is a positive milestone for proving this system hosts grades as well as volume — over 100m of copper sulphide mineralisation with multiple high-grade zones is an outstanding outcome. Every hole to date has hit copper mineralisation, reinforcing the strength and continuity of this system. While drilling has been slower than planned, both rigs are on priority targets and we’re confident the coming weeks will deliver further strong results. We are extremely excited to be drilling VT2, a ~500m-long, highly conductive plate independently reviewed as likely sulphide-sourced, and mapping over VT1 has already returned copper, gold, silver and tellurium directly above a strong conductor.”
Next steps:
• Assays fast-tracked to confirm copper, zinc, gold, silver and associated elements from OGRC010 and other recent holes
• Follow-up drilling across the eastern IP anomaly and along the VT1/VT2 conductor corridor
• Ongoing integration of IP/VTEM, geology and pXRF to refine targets
