"Is this deposit really economic??"

A good question, speccy. You would need to see a cross section showing that one hole in relation to the others.
"but while the grades are ok, the widths are nothing special."

The grades HAVE to be taken in the context of the width.
All those values came from one hole, the majority between 128m and 148m......
Quite a depth. Who is going to dig down there and get to them? Remember you have to sink a shaft wide enough to get down there and work, and swing a shovel.
And you certainly wouldnt dig a 150m deep open cut to get there, eh?
All depends on how it looks when other holes are plotted in cross section and the details of the values, widths, of all reefs, leaders shown.
Back to bed for a while, mate.
