Ann: West Arunta Project - Luni MRE, page-202

Some geology.
Core of carbonatite (matches gravity high at scale available to me); surrounded by carbonatite complex and then out into a fenite alteration halo.

Pretty standard(?) pattern which is obviously preliminary . Constraints becoming weaker going away from the most densely drilled areas.



Phoscorite - vaguely heard of these beasts but need to look up some more. FYI

ABSTRACT

Phoscorites are plutonic ultramafic rocks, comprising magnetite, apatite and one of the silicates, forsterite, diopside or phlogopite. They almost always occur in close association with carbonatites. Common minor minerals are calcite, dolomite, phlogopite, tetraferriphlogopite and richterite. Key accessories are baddeleyite, pyrochlore, pyrrhotite and chalcopyrite.

Phoscorites are rare rocks and only 21 occurrences have been found worldwide. They often form multiphase phoscorite-carbonatite complexes and field relationships include girdle,

The larger black dots represent sentinel interpreted sites in 2024. INTERPRETED so may or may not be real or drilled. Most will have seen a drill rig IMO. Results are obviously not back to inform this MRE but will be for later this year early next year to get to the desired indicated + some measured perhaps.

No major surprises, for me with this. The NW and NE trends towards ENR ground have been relatively obvious. What they yield is currently been tested with aircore. The NW trends offer interest to both WA1 and ENR with Emily open to the south onto WA1 ground.

Not much sentinel activity to 27/6 with this summary
RED activity 22-27/6. Few other disturbances of more subtle nature over last 10 days.
