Stu Gardiner & Estelle Sandford
With only the 2 of us due to the others being struck down by flu we set about continuing to break down the calcite boulders, these as expected were still difficult to extract in decent sized segments, however a fairly good piece was removed from the right hand side with some well placed feathers.
The solid calcite 'wall' directly in front of the dig was becoming quite tricky to break down so we set about digging over the top into loose spoil, this exposed the calcite blockage from the top allowing us to feather it from the top down, around 30% of it still remains but another session should see it removed.
There are now 2 clear calcite boulders that block the majority of the passage and pre drilled holes have been placed in these in preparation for the next session.
Part of the roof was also removed in an attempt to create a little more working space as the dig face is becoming cramped, this is due to the floor being extremely compacted and almost impossible to dig.
Note: the 36v Li ion Hilti made light work of drilling the holes and the new shorter 14mm SDS bit made drilling in confined spaces easier.
Total time underground: 2.5 hours
