SensOre’s pre-drill interpretation was that it was a pipe-like, multiphase, altered intrusive with associated iron - rich magnetic alteration and metasomatism surrounding the central dense central body. Moonera’s geophysical signature shows characteristics of being one of a carbonatite, IOCG or porphyry type system which gives the target outsized potential if mineralised.
Highlights
- A 733m core hole on the Moonera target in the Madura province of WA has encountered a fertile igneous complex from 458m depth
- Intermediate and granitic style rocks show strong alteration over wide intervals with strong oxidation
- Fertility indicators from whole rock geochemistry are indicative of an oxidised granite related mineral system with signatures commonly associated with Magmatic Hydrothermal IOCG’s (MH IOCG), alkaline Porphyry and Cu Au breccias.
- SensOre believes this is a very significant result and heightens interest in this large target and the Madura province more generally
Moonera Overview
The Moonera prospect is a large, circular (7 x 5km) dense and magnetic body.
The Madura province, east of the Fraser Ranger province is a newly emerging frontier exploration region that from regional geophysics clearly has complex and interesting basement geology beneath extensive cover rocks. Location of the project and the drill hole in relation to the regional geophysics is presented on figure 1 overpage.
Moonera is the first of SensOre’s next generation base-metals targets resulting from an expanded application of DPT on its proprietary hyperdimensional data cube. SensOre’s technology has great potential to improve discovery rates for rare earth, battery and critical minerals. Moonera is a joint venture with private company Nullabor Resources Pty Ltd. SensOre through its 100% subsidiary SensOre Yilgarn Ventures Pty Ltd can earn up to an 80% interest in the prospect by expending $3 million within three years.

Drilling Results
The drilling cost was supported by a successful application of the Western Australia government EIS grant.
The hole was the first to successfully drill through the cover Madura limestone sequence and into the underlying older basement rocks. Basement was reached at 458m to a final depth of 733m. The drill hole was sighted following infill geophysics and subsequent 3D combined magnetics and gravity geophysical inversion. Location of the project is presented on figure 1.
The drill hole encountered a multiphase, strongly altered felsic intrusive rock sequence comprising monzodiorite, syenogranite, granite and granodiorite. Drilling intersected extensive alteration that is commonly associated with mineral systems which was verified by geochemistry and petrology.
