Ann: Cuba, Block 9 - Mobilisation Commenced, page-237

So just for those who forget what was stated by AP in the 25th May ASX release, in part:
".... Our CFO and I will be on-site in Cuba for the month of June to oversee the commencement of drilling, leading up to the expected recovery of first oil samples. Now that activities are accelerating on site, the Company looks forward to providing a steady flow of updates into
spud and throughout the first phase of this year’s appraisal drilling program.”

So anyone who actually wants to be a holder for the drilling should have got on already, but if not I'd suggest you better get on quickly, as we should be about to get another announcement of the spud.
And knowing that AP is on-site means we're not waiting for a delayed announcement coming from Cuba.
My feeling is the spud announcement will be on Monday.
