Ann: High-Grade Rare Earth & Niobium Zones at C3 & C5 - Mangaroon, page-46

Time will tell if the results are economic. HAS experience to date suggests it isn't going to be easy but certainly an interesting start.

Headline assay results highlighted on the image above.
Focusing in on C3


Generated a section for the northern fence here. Preliminary results with 126 and CD 7 and 8 to come. Were the lower parts of the hole triaged by Pxrf to be assayed later if at all.


Residuals for 115 and 116 0.8%/73m & 0.6%/89m resp.

Apparent sub horizontal correlation for the higher grade on this section.
Approx. 80-100m vertical depth to higher grade on this section.
Hole 117 is possibly anomalous for the lack of above cut off TREO in the upper 68m. Syenite is logged on the margins of "ferrocarbonatite" to north and south though "joining the dots" suggests the contact is further west but is a possible explanation for the low TREO.



======================================
Five holes have been assayed for the beginning of the C5 extension.



One possibility is these holes are drilled close to the contact between ferro and magnesio carbonatite units. The former is apparently a more favourable host for various mineralisations. Too early to be certain of this but early sections give a hint.



Hole 111 is some 40m west of the section and projected to it. The interpretation mentioned above is one option - could be preferable as more potential is wide open to the west and SE.

Moderate to strong correlation of REEs and Niobium in 110/111 plus with the interface of saprolite and saprock. Depth 50+m.

============================
C7.


[@Poodleface you asked about the clarity of imagery earlier. Did you mean the GE above or sentinel images?

GE updated this area in early May so it is possible to see the access roads though not drill sites that were drilled later. Good imagery for Yin/C1-5 Hastings etc. Sentinel does seem to be getting better but up to date imagery (yesterday! or this morning) like the above, or better tends to be expensive. ]

No comment from DRE on visuals or PXRF here. Patience to find out if there is carbonatite and then if mineralised.

5/7/23 image C1-5 +carbonatite. Oversight for C7 or real that no Carb. there?


=======
MRE in August for C3.
Probably a good geological model and consistent grades around the 1% range for much of the area. Would be good to have more higher grade and that may come from local infill drilling.
Depth to mineralisation is variable and needs better grade and or volumes for deeper zones.
Polymetallic - swings and roundabouts for economics. Good if cheap to extract not so for the reverse at any depth.

DRE will produce an MRE that could lead to a Scoping study/PEA.... etc.

Hole 25 and other gaps suggest possible extensions to C3 - though quite well constrained.

Hole 10 CD1 have not been followed up yet...
