At the current end of Merlin's, following the south-west leading gap, drilled 6no. hole in the floor, to continue the expansion. Struggled to drill the holes at first but, a squirt of WD40 solved that issue. I raked a lot of sediment out from the way forward to use as tamp, in doing so, got a better look at the prospects - they look interesting. The small passage appears to get a little bigger, dips down and, possibly widens to the north-west side.
The evening's task was brought to a satisfactory conclusion. Should be plenty to clear on the weekend.
