Logic says staggered drill hole results through from 2-7 between now and end Aug.
Otherwise no reason for 1 hole to be returned end July and then a 4 week delay for holes 2-7 if all samples were submitted for analysis at the same time. Normally either as available or all in a box with a bow around it when 100% complete.
Assuming good actual numbers the staggered approach would be a serious rocket IMO.
