This is very rough.... but dividing the proposed drill line into 6 segments (i.e. 6 weeks) gives a bit of an idea when they will start hitting the interesting bits.
It is rough because the early phase of drilling will result in more metres/day and it slows down as the hole gets deeper (withdrawing the cores). Also they will probably be going slowly to try to avoid the hole deviating.
So... on a rough basis...
by next Monday they should be entering the halo of the deposit (assuming there is anything there).
