Ann: Shallow, high grade niobium-REE mineralisation at Emily, page-31

"Playing" around with the distribution image from Geoscience analyst. Was thinking of doing something along these lines but this is so much better as a base.


Data dump of my sentinel interp and announced hole collars.
Purple squares probable drilled sites NOT reported yet.
Green squares sentinel sites not obviously drilled but DYOR.
Huge number of assays on 100m spacing to come in for Luni. Plus at least 6 of the 12 holes from the X zone perhaps more in the center east of Luni.
ENR assays shown with some anomalous at Emily and Green where hole spacing is 2-400m E-W and 100m along lines in some areas but 200m elsewhere.

What do these data points suggest for carbonatite distribution and grade?


Assume holes without Nb are not carbonatite related (fenitised is a possibility - marginal carb. alteration but below cut off Nb REE grades)
Grades assumed to equal carbonatite - probably reasonable though not the best of assumptions.

Same for Gravity base



Geophysics is not a one to one correlation with carbonatite. At the AGM further research was going to be done from analytical results received to try and work out if there is a useful geophysical technique to zero in on carbonatites. At the moment geophysical targets are providing carbonatites when tested by drilling but there is little obvious consistency. So much carb. there that hitting is currently greater than missing - P1, Wild?, Caird, Green centre/west misses.

Does Luni extend westward to Emily? and east/NE along the circular magnetic trend to eastern Green?

To the west the magnetic feature associated with Sambhar (BIF) to the south of Luni extends weakly and may represent a cut off for Luni to the west on either a lithological of structural basis. WA1 have some idea having put in two 'wildcat' holes into isolated gravity blips west of Luni.

The distribution of grade in Luni gives some idea of the variability to expect as more detailed drilling takes place and assays FINALLY roll in.

Detail contour FWIW



Simplified contour with sentinel holes showing what is to come once drilling is completed. Probably not for quite a while and maybe 50m infill in higher grade areas plus expansions on the marginal testing.


The contours WILL change as more results come in.but with orange at around 1.5% the areas of decent grade and significant thickness of supergene are large enough to represent volumes that come close to justifying WA!'s SP.

ENR, at present, seems to have chosen poorly along the Luni boundary. Not certain but suspect the ground may have been available to them when the initial tenements were pegged. Have to stop somewhere.....
