Perhaps read the whole announcement and not just skim the table.
These results are just from surface samples taken during the DD and the presence of strong copper mineralisation is a positive indication that the geology is similar to that of the Bou Azzer mine next door, which had high grade surface copper mineralisation and the cobalt being extracted from underground operations.
I have no concerns with the surface cobalt grades as it was not expected that there would be high grade cobalt at surface in any event.
