Ann: High-grade Niobium Intercepts at Crean Carbonatite, page-317

Some geopoetry on P2 for weekend Fun.

The drilling and geophysics give some constraints but too wide spaced for drilling to be really helpful.



The red gravity high envelope around P2 is generally similar to the one at Luni. Carbonatite and fenite in association with surrounding gravity highs probably related to gneissic units (23-3 and the western 2022 holes as examples of local tests).
While Luni is shown as concentrically zoned (Carb. core, complex, fenite, country rock) the two western holes suggest a different distribution of carbonatite at P2.
The purple dotted line puts a wide envelope of carbonatite around the 3 eastern holes which all contain it from base of cover to EOH. The southern/SE margin is assumed to be the margin of the gravity high consistent with a partial Luni model. Very likely there will be a fenite halo and perhaps a complex zonation around the carbonatite.
What happens in the western side of the P2 gravity high is only constrained by 23-4, 5 which contain fenite but leave large areas of potential for more carbonatite.

With existing assays the western side appears poorly endowed.

The east does have hints of a possibly consistent shallow blanket with grades up to 1.5% over relatively narrow intervals. This zone is at least some 2 Kms long and up to 500m wide narrowing in the east. Plenty of space for a reasonable to good deposit. PROBABLY TOTALLY WRONG BUT AS ONE FIT FOR THE CURRENT DATA a possible starting point.

Note the comments about variability in this video about ENR results thanks @hrdwk.

Some potential but Luni blows over most other targets with P2 put on the back burner for now...apparently. Won't always stay there IMO. I suspect the success ENR have had with Aircore drilling may mean it is used here and elsewhere, as appropriate, on WA1 ground.

Going east it is some 6+ Kms along strike of the P2 trend to ENR's border where the outcrops show a NW-SE strike towards the Luni area.

Real arm waving going east to ENR ground. It is an ENR site.



The postulated fault south of P2 goes NE into a low grav/mag area. The image above shows two possible trends.
The blue one a potential extension of the Elephant Island Fault to the WSW with a blow out at P2.
The strike of quartzite outcrops controls the eastern trend of the yellow line which passes the Shackleton anomaly.

Put these lines on without referring to geophysics.
Magnetics supports aspects with a complex area suggesting the EIF may stop east of the ENR boundary near McIllroy.
The SE trend does seem a different domain to that containing P2.
Complex area.

Shackleton is a moderate grav peak but low magnetics. REE's to 0.5% in surface grab samples, from memory. Not included in ENR's current target listing.
