Near surface grades >1% are 'bulking' out the overall grades. There will be some variation but the deeper zones are likely to average <0.5% which may not be economic unless treated porphyry copper style bulk. I would not expect this to happen.

The calculations above are pure math and need to take in actual grades below the 1% zones to determine if there is something showing up at depth as holes go into fresh rock.

PXRF vs assays


Schematic representation of assays.
All 1%+TREO in upper parts of hole.
Circles mostly for Pxrf values less than 0.2% but not all.
Some assays came in above 0.2% suggesting the XRF reporting is not definitive at lower levels. To be expected perhaps.


PXRF comparison suggests good potential for Hole 10/ Diamond 1; also for the 6 zones outlined so far but not all results received.
The depth extensions of C3 infill may not be high grade. Expect some zonation which could be positive.

================
Phosphate/Ti, Scandium relative to REEs?



Complex relationship with these and REEs. Some do not correlate others do.
As with the REEs the P Ti and Sc appear to be mostly in the weathering profile with the possible exceptions of hole 41 and 48.
