Bomb Diggity sits in a structural hinge zone surrounded by multiple intrusive bodies. Long-lived conduits are thought likely to have been created around the hinge zone and remained open to repeated mineralising events – a classic setup for big systems like Mount Isa, where early SEDEX mineralisation has been overprinted.
Litchfield Minerals managing director Matthew Pustahya said: “This maiden diamond drilling campaign represents an excellent first test of what we believe may be a later-stage, intrusion-related mineralising event associated with gold and bismuth. Phase 1 RC drilling confirmed a large mineralised footprint and, importantly, the presence of two potentially distinct mineralisation styles, an earlier copper-zinc system and a later gold-silver-bismuth overprint linked to intense magnetite alteration.”
The second diamond hole will plunge 300m into the main Oonagalabi zone and include the curious magnetic finger-like extension that appears to be directly linked to the original gold-bismuth hit. This could be an important conduit for the later intrusive event.
Versatile time domain electromagnetic geophysics (VTEM) has lit up multiple high-priority conductors across the broader corridor, many of which sit on or close to the numerous magnetic features previously identified in earlier studies.
Litchfield believes they are genetically tied to Bomb-Diggity and the other nearby intrusions. If proven, those conductors could massively expand the company’s target inventory along the crustal boundary between the Aileron and Irindina Provinces and could completely change the overall picture – and the company’s fortunes.
With drill rods already spinning and the Northern Territory Geological Survey backing the play, Litchfield’s intrusion-driven model is getting its first proper test.
Early signs – including multi-phase mineralisation, strong geophysical alignments and open scale – scream potential for something substantial in this underexplored NT belt.
If drilling hits paydirt on these multiple geophysical bulls-eyes, the Oonagalabi story could quickly transition from intriguing or promising to a definite must-watch.
