I might not agree with your time frame respectfully.. If all goes well in this new hole 2 months approx. should complete the mother hole... while one month should have us in the Balmer.
I would expect core from this Balmer area and deeper will be sent to lab if anything is found in core .
One month plus and a month for lab would be 2 months so anytime after early May , we could see some results..
Any delays. would of course. lengthen the time frame..
My guess is the middle of May.. so lets see how close I am
Best regards to all
