Ann: High-grade Niobium Intercepts at Crean Carbonatite, page-321

An interpretation of the analysis mentioned in the video (12-15m) for Green.

Base data.
ENR holes 82,3 both had long lengths of what ENR logged as carbonatite. Nb grades were <0.3%'

WA1 drilling and MRE geology are shown.
Inside the blue dashed line is called carbonatite with a ring of mixed carbonatite and other lithologies out to the yellow dashed line. Beyond this, and not well defined is a fenite zone grading outwards to country rock.

WA1 gravity survey didn't extend to the east which means their interpretation is open in that direction...optimistically towards Green.

The easternmost holes at Luni (105-108) give an indication of depth to blanket mineralisation (c40-60m at -60 degrees) in RC holes extending probably to 166m in fresh rock. IMO a good sign that the Green aircore holes will be able to provide an adequate test in some if not all areas drilled.
Good grades in holes 105-107 Luni holes is encouraging but may be at the eastern margin of Luni with the gap to Green largely on WA1 ground.

Approx. 95 aircore holes interpreted for Green. If all drilled to the average depth of the first 4000m (~80m), then this represents 6-8000m.


INTERPRETATION
A variant of what @2ic put on awhile back modified along the lines described in the video.
Single intrusion;
Multiple intrusions - nested/telescoped.
Some subtle irregular mag features in the background to the arcuate ones. The aircore drilling may give an idea what some of these zones/features are if they penetrate deep enough.



Gravity

Luni gravity involved an early wide spaced survey (400x400m from memory) with a follow up 100x100 over the gravity high zone. The broader zone does show a weak ENE ridge that roughly aligns with the weak zone in the falcon survey. Would be interesting to get an interpretation from the company. Grasping at straws, probably, but hints at some possible continuity with Luni albeit indicating a variant.

=============================
Collation of interpreted sites not including announced collars.
Green c 95 holes
Crean West c 25
Crean East c 12
Hurley c 20
Caird c 20 sites.
Emily c 8

Total c 180 interpreted sites. Many uncertainties with this number most likely to be at the high end. Actual drilled holes likely less.

If all these were drilled to the average c80m of the reported 4000m then not much left in the budgeted 20 Kms.

I suspect the Crean west holes were not ORIGINALLY planned.
Perhaps the relatively completed coverage at Green may not have been planned, but (wishful thinking) results from initial holes were good resulting in the reported priority sampling.
Imagine WA1 had peppered Luni and P2 with aircore in 2022 the basic outlines would have been revealed. Easy to say in hindsight.

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

Something odd happened to the Sentinel satellite imagery over the West Arunta on the 12th of July. No imagery for a large portion of that pass but coverage east (Qld) and west (Carnarvon) on same day. Next pass 17/7.
