Interesting observation Rozting, certainly the same pic. But perhaps you're reading too much into it to assume both rigs were on site at the same time.
Regarding the drilling itself I'm not aware as to whether the operation is proceeding double shift or just daylight hours? Have there been any drilling restrictions imposed by the relevant department I wonder. I'm not in a convenient position to be contacting the company office to check, but I'm sure they would be unlikely to say when they're close to the zone of interest - noting vertical depth to the zone appears to be more than 400 metres.
