This is good news!!My point of view is this
Regardless of expectations they hit more copper which tells me their mag survey, IP and other methods outside of drilling are accurate. Because of this I would say these other clusters do have copper and if the conditions are similar or slightly better we have pretty extensive fairly deep oxides.
Its not 400mt of sulphide below MOD but it expanded the resource and to me confirmed their methodology and reasoning for further drilling, they were right.
