Overview
- Litchfield has started a maiden deep diamond campaign at Oonagalabi, co-funded by the Northern Territory Geological Survey, to probe two intrusive targets including the Bomb-Diggity body.
- The first hole is designed to 700m and a second to about 300m to assess whether intrusions acted as heat and metal drivers for the corridor.
- An induced polarisation survey is underway to track blind extensions of the Oonagalabi Formation toward Silverado and along a magnetic trend to the high-conductivity VT1 target of about 3000 Siemens.
- Earlier phase-one RC drilling defined a multi-element footprint with copper-zinc mineralisation and a later gold-bismuth overprint, including broad Cu-Zn intervals and a 15m gold-bismuth hit from 50m.
- A separate reconnaissance at Silver Valley mapped sulphide-bearing quartz reefs and historic workings, with a gradient-array IP survey planned for late February after Planetary Geophysics completes the Oonagalabi work.
