We are all awaiting anxiously but given the 27mm of rain yesterday and an extremely wet winter, we will be extremely lucky if we can get in before end of April.
Don't worry we'll let the forum know as and when.
Digging has paused as we've lost the draught and the route down is digging through fault breccia. We suspect lower down is flooded. As soon as we can get to the end we'll redo the smoke and sound tests. Very frustrating....
