So to confirm, the issue isnt hole 8 being a duster because they went the same spot just underneath it immediately afterwards and got 21m of mineralisation.
The issue is Hole 7 and 8/14 have less mineralisation and massive sulphides than 1-6?
Based on geology why would it get worse as you go deeper "towards the source" as it were, and is it common for these things to be inconsistent as you go along?
