Ann: AVZ Delivers Positive Drill Results - Manono Project, page-22

X section on pg 3, 4 clearly indicates that 2 of the holes were to establish the pit boundary on the NW hence shallow depth of 72m & 92m with less pegmatite.

Whilst the other 2 DD holes, (ie #2 & #4) r in the guts so had a large Intersection.

Good result for AVZ, especially after dewatering the Pit & that's allowed them to access the pit floor & drill directionally to fill up the missing bits.
I'd expect the next section line to show similar sort of results, i.e thinner pegmatite body towards the existing pit's edge & thicker in the guts.
