RE: Could be economic .Just to clairify " it will need more drill holes with those long intercepts and the deposit at surface to be economical " .
It will also need the grade of Au and Copper to be close to 1 % ore in order for it to be economic . The drill hole gave some indication that it may be on the edge of the deposit so better grades may show up .
The greater the tonnage the lower the grade they can play with . If the upper and lower zones are connected near surface then they will have a big deposit .
