Crean data.
Not 100% certain but left image is a plan view with assays to date.
Right image oblique view.
Both show greens and yellows for grade - probably in east as lower grades than the highlights so far.
Variation is to be expected in grades and widths. Hopefully within reasonable (potential "ore grade" )range - Can't see the scale for the colours with red probably 1%++. - the rest would need to cross reference.
Agree the collar elevations need checking.
Mix of drill hole azimuths north and south.

==========

Weathering of mineral deposits creates variable metal dispersion patterns. Gold tends to produce more of a mushroom pattern above a feeder than what appears to be more the norm for the Nb distribution above carbonatites. A generalisation that would need much more study than I have given it,
Luni and Crean and Emily (limited observations for latter two) appear to have had limited mobility of Nb in the weathered profile other than perhaps in a vertical sense. Mt Weld possibly displays a similar pattern for both REE and Nb. A reflection of primary sources somewhat enriched and then concentrated very locally by weathering processes?

The concentration in the weathered profile is what makes Araxa (Nb) and Mt Weld (REE) such good deposits.
The variability of Nb in sections shown by ENR gives a clue that some form of concentration process is occurring.

The wide intersection in 98 vs the below cut off grades in 94 and 95 hints at some zonation. Perhaps some lateral enrichment in 227 and weathered zone of 94?

There is Nb2O5 in the primary zone at both Luni and ENR prospects however the depth in fresh rock, and scattered distribution seen so far make this style of mineralisation a low priority target IMO.

With respect to Crean (Hoschke) the fresh carbonatite shows a wide variation in thickness along strike. The above comments about weathering and variations of grade material come into play. There is a hint that something different is occurring with Nb (+-?REE) distribution at Crean with residual Nb a lot higher than the average Luni holes for the first pass assays.

Cross referenced the eastern assay results for lines 200 and 400m east of the highlight assays in this announcement.

Two intersections, one on each line, at 1%+ Nb2O5 plus high back ground residuals (c1%).
These reflect the assays in Hole EAL008 -34m 1% with4m@ 4% (residual c0.5%) a further 200m east.

The current sweet spot is open to the west with narrowing to east and lower grades.
The priority of assaying does give a hint of what might be expected in grades.

Lots more to come from exploration.
