Hi Zoros
The amount of water entering the evaporation ponds have been witnessed to be reducing from the satellite images, I’m expecting these to have risen with the rain the other day. Less water coming out indicates the pressures has dropped in the aquifer.
I think they will be using these bore holes shown on this plan:-

Hahy003,006 HaGy 008,009 and 011 I don’t know the other one.
Each bore hole will be pumping intermittently as the hole fills , if the pressures have dropped it will take longer to fill before pumps comes on.
The bore holes will be drawing water in an area around each hole, the ground between each borehole will dry up first and not be able to recharge so less water area will be draining eventually allowing work to recommence.
I couldn’t state for sure what date they will restart on but they will want the ventilation works well underway before they recommence.
We’ve seen a slight increase in the Decline length from last time as it stops just above the aquifer.
The vent works might take to the end of March with a fan installed at surface, I’ve been trying to see the satellite images for evidence of that, there was no sign on the 20th January image.
Shaun mentioned on Sunday that the dewatering was ahead of schedule, he’d only know that if it was depressurised, if the ponds were filling quickly then it wouldn’t be depressurised.
