"Now, going back to my estimates they are for the area around holes 1 and 2 (2017) where the current drilling program (i.e. the current 20,000 metre program) is targetting)."

I did understand your reference was around the first and second drill holes. But it seems to me your calculation assumes drill holes parallel to each other (which is ideal for maximizing volume but not what they are actually doing). I think the volume sampled decreases in practice though as the drilled holes are not parallel.
