Cross section of drill holes12 Nov 2021 11:55
I've just been looking back at the cross-section diagram's released to date and comparing them over time.
I'm new to investing in mining companies so may be completely misinterpreting this, however have found this slightly disconcerting.
This is the diagram released with the announcement of completion of hole 22 on the 2nd November :

This is the diagram released today with the assay's for hole 11:

Comparing the two, the green 'mineralisation' zone has been dramatically reduced in the later release, as has the yellow 'high grade' zone.
Does this indicate that hole 11 didn't intersect copper in significant grades through the full width of that zone and it has had to be reduced accordingly?
From the hole 11 completion RNS dated 19th Aug:
'The hole passed through 512m of visible chalcopyrite copper mineralisation from 110m, with two zones of stronger mineralisation noted within the main (western) part of the deposit within intervals 130m-173m and 282m-444m. The eastern flank of the deposit was intersected with a 49m wide zone of visible mineralisation between 573m-622m.;
Vs the hole 11 assay RNS released today:
· 18m at 0.38% CuEq (0.14% Cu, 0.41g/t Au, 0.5g/t Ag) from 142m
· 18m at 0.25% CuEq (0.05% Cu, 0.35g/t Au, 0.4g/t Ag) from 220m
· 78m at 0.32% CuEq (0.3% Cu, 0.02g/t Au, 1.00g/t Ag) from 294m
· 16m at 0.47% CuEq (0.44% Cu, 0.03g/t Au, 1.80g/t Ag) from 342m
The initial drill results indicated intersections from 110m - 622m, the assay indicated intersection from 142-424, this appears to correspond to the narrowing green area on the cross-section diagram.
The zone width has also been significantly narrowed deeper down near hole 15, would this indicate they have received assay's for hole 15 and this too has not intersected copper where expected?
Any thoughts on this?
