Ann: New West Arunta high-grade niobium intercepts -Crean & Emily, page-72

Back home with a lot of data to digest.

Noted in the video that there was a diamond hole near Hurley. Hadn't spotted it on sentinel but could when I searched the specific area.
The idea of hardcap is probably wrong as there is deep cover that has proved difficult for RC and by extension likely so for AC.


Red circles highly interpretive AC sites with not many drilled ...perhaps.

As @2ic commented initially Hurley is at best borderline with depth and low grades suggesting it is low priority.

8 RC holes in this image area have failed to penetrate cover with no reason (I have seen anyway) why this is the case.

The green boundaries are purely schematic envelopes. A wider portion of the Elephant Island Fault carbonatite dyke perhaps. On rough trend with a weak to moderate gravity feature coincident with the carbonatite intersections. Hole 34 has some 1+% Nb grades in 3 widely separated 4m intervals


Holes 29 and 30 are fairly represented of grades in other completed Hurley holes.

The diamond hole would have to be deep to test the full NS extent of the schematic width. >600m and as much as 1000m at -60 degrees. If this deep they must like the target for some reasons not obvious to me.
At or near the interpreted intersection of the EIF and Stromness faults is one reason but a valid one?

====================
Crean West


4 more fences to the west 750m with sites nominally 40m along each (most scaled so DYOR)
Yellow stars holes with high grade, Thin yellow lines vertical projection of grade margins - very rough.
Trend line approximately in middle: open to west, for now, and extends to the east but zone narrows, and grade drops off, relatively quickly.

===================
Emily


Rough vertical projections of existing grade zones in red;
pending results will be very interesting.
200 or 400m spaced lines? Probably 400m line to see if there is any continuity to the west of 98/225/260 or any surprise depth increase or other surprises. Good then 200m which will be done anyway at some point given the grades and indicated continuity in the "sweet spot".

========================
Liked the interpretation of Green in the video.

Rig has probably finished the planned extension work at Crean west (for now) and will do further drilling at Emily and Green!!

Another tick for Green prospectivity I hadn't noticed before. Priority sampling good, but drilling again (probably) before results are in, would be something else IMO.

===========================
Statistics from reported AC drilling to date.

48 holes drilled for 3988m gives an average of 83m per hole within a range of depths from 39 to 135m.

RLs range from 305m (Crean #183) to 421 (Crean 251). Emily RLs mostly pending. No way there is 100+-m of topography at Crean.

16Kms of the planned 20Ks remain. Already a significant number of Sentinel satellite sites interpreted as drilled especially at Green so likely close to half of the budgeted meters drilled.

Using AC for resource calculations surprised me a little. Makes sense given the system does generally give a sample quality that is akin to RC. Choice by the person who signs off on any resource.
