Around two months since I last gave a Sentinel update on WA1 from a quick check.

Not really been much to report with a steady, but slow, increment of sites prepared and some drilled within the main "guts" of the deposit.
This has changed in the last 10 days or so with the main addition being the preparation of access to the east into E80/5656 where the probable connection between Luni and Green may finally be tested. Not done before because of POW's or some other reason?

Several kilometers of grid lines visible and shown in light blue.100m spaced lines in the NW corner of the block. No obvious site preparation yet so maybe aircore for a first pass. Hint of what WA1 are chasing with the first two lines for eastern extensions from 2023 holes 105-7.

ENR have been setting up infill on their Green Target and recently appear to have begun drilling on the eastern lines. The red outlined areas are my vertical projections of better grade Nb (often 1%+) to surface.

=====================
Activity continues in the main part of Luni with the focus east of the X. None noted in the western extension.

I have not followed the activity in much detail so the images below are probably missing some details.

Time lapse for Luni + Green area for last month.

Activity in the last 5 days.

What looked like drill activity as shown above is probably site rehabilitation. As I called this drilling and then cross referenced with previous drilling something seemed wrong so Rehab is the most likely reason IMO. Mixing that in with ongoing drill related work at this resolution means errors will creep in to the interpretations. Almost inevitable with this drill density and the irregular nature of my efforts. May do the work to bring it up to date but for now just some old work combined with the recently reported assays - collars shown as magenta hexagons

East end

orange stars March April Sentinel interp. Yellow stars recent activity.

Main reason to put this image out is to show some sites have been prepared but not (obviously/reported) drilled (green dots). Most are marginal and therefore unlikely to result in any material results.

West End
White line heading NW is rough axis of a zone of higher grade Nbx that extends towards Emily.

Some very juicy intersections reported here (and previously).

Sentinel interp has been reasonable to good till recently but getting much trickier and more time consuming in the high grade guts of Luni where such work doesn't add much to what is already pretty much a know. There will be local variations to grade and thickness but this is mainly detail infill that will be reflected in MRE's rather than initial exploration as is the case to the E and W of the well drilled areas.

Expand

Clear pass 5 days after the above and extension preparation is progressing in a similar pattern to the initial Luni work. Mostly 400m spaced lines with holes at 100m spacings (so far). One site may have been drilled just east of 2023 hole 107 (39m @ 1.5%).
Preparation for later(?) infill 200m lines has been done for the first kilometer from previous work. Another 600m is available if results warrant.
Red line an early interpretation of possible carbonatite contact.

As above with a data dump

Green mineralisation appears to be constrained within more dyke like zones than the main part of Luni.
Similar to the NW extensions of Luni towards Emily perhaps.
There has been enough drilling done to show this (narrow zones) is probably a reality where work has been done away from central Luni.

Some highlight assays for the red outlined area just north of WA1's recent preparations include:
ENR RC hole 489 10m @ 4.2% from 57m
ENR RC hole 500 10m @ 4.3% from 47m which is 400m east of 489.

This section is from follow up 2024 drilling between these two holes.

Typical of many ENR zones. Nice grades, reasonable to excellent strike extent but limited NS width. Depth likely to be similar to WA1 in Luni with high grade in the weathered profile and potential for irregular grades at depth.

This 'competitor' data is given to show what might eventuate from these eastern extensions by WA1.

IMO the eastern margin of Luni will be outlined with a marginal phase extending up to Green.

This marginal phase is not small, but so far appears to be zoned in some way with perhaps two phases carrying higher grade.
Back of the envelope for a lower cutoff at Green came in at 31 Mt at 1% Nbx from 6 separate zones. As with Luni there would be a higher grade component around 20% of this.

PS I no longer hold ENR but retain a strong interest in the overall area.

A pity, in some ways, that the mineralisation has been split along near random tenement lines based on IOCG copper gold targets! Such is life and exploration.

Detail for recent work 18-23 May:

Size of circles shows level of certainty for interp of drilling.

Some activity ongoing in the main eastern area - to be expected but unless it is "material" I'll take it as infill as usual and beyond what I really am interested - exploration extensions.
