Adding a bit to@Wack 's post I had also noted the recent tenement additions. Different perspective on the same things.

One question I had was who was following who. Nearology? or Synchronicity? I suspect the latter, perhaps following the release of some government information or other that put the area into focus back in early 2018. Probably in announcements at the time.


Local only with ENR and WA1 in the list.
ENR were the first movers applying for land followed some 3 weeks later by the first WA1 tenements. Agrimin expanded their Lake MacKay holdings on the same date as WA1's application.
These first applications by E and W were probably focused on magnetic anomalies.
Subsequent tenements for ENR/NCM covered the extent of the magnetics which do extend east into the NT where IGO have been active for sometime mainly with Au, but also base metals. Some open ground in the NT along the magnetic trend was picked up by WA1.

WA1 added the small tenements (5,6) in mid 2021 in what now looks like a wise move.. Tenements 7 were added to cover strike extensions of areas identified by fieldwork.

Since the discoveries at P2, and now Luni, WA1 with drill hole information in hand (probably), decided to secure the northern and western flanks of the magnetic zones. Geoview magnetics and tenements (to 15/11/22)




Apart from minor parts the more eastern WA1 tenement application, the depth to basement may mostly be too deep for easy exploration drilling in the area north of ENR ground.





The strength and definition of the magnetics gives a clue as to the amount of cover. Weak or no anomalies probably deep cover. The 8 holes reported to date have all intersected basement from 10 to <100m.

The shelf/shallow polygon contains a few subtle magnetic features which may be at reasonable depths below cover.

The basin floor (Canning Basin) is probably uneven and/or there are local very strong magnetic zones that can be picked up even when there are multiple hundred metres of cover.
[ Havieron (400+m) is one example. Others seen through basin cover include Olympic Dam (300+) and Carrapateena (400+)]

The latter two are one reason the area has been a target for IOCGs for decades.

Then WA1 finds carbonatites, and REE/Nb happen to be very much sought after these days. Paradigm shift?

===========================

Gravity surveys - ENR and WA1 with more to come from Encounter and probably others.

Compilation of existing gravity (all that is readily available at good resolution - assumption)




Carbonatites are known to form along major structural trends. There could be a weak, discontinuous, magnetic trend between Luni and P2 with some interesting gravity and magnetic anomalies WNW of Luni on ENR ground.
Expect a majority of the high magnetic anomalies to be associated with magnetite/+-BIF and perhaps hematite alteration as at EA01. Note an expectation that may require many of these targets to be drill tested to confirm this.

Taking the white gravity high outlines and putting onto magnetics:


Some simplistic magnetic trends which may or may not be real in red. The trends break down near Luni and P2. Folding and faulting are apparent in the magnetics.
Do not expect a string of pearls of carbonatites along the mag +- gravity trends.
This is a 2021 image with several targets for the IOCG model. ENE faulting is interpreted in the Luni area...
Looks like Agrimin potash may have some targets on their ground in the east of this area.


===========================

Niobium is worth a fair bit these days.
What would constitute ore grade?
What is the supply demand situation. I have vague memories of a large mine in Brazil that could potentially flood the market or at least satisfy most of demand with ramping up their production. Very vague. Anyone got some info?
