We always figured that we hadn't traversed the full extent of the workings westwards - the mine was eight meers long, with one to the east of the founder, I think, so we should have had at least one more meer remaining westwards, which would be about right. The blockage in the western cartgate would have been a reasonably straightforward job, where it not for the torturous (and somewhat harrowing) route to get to it - and take all the necessary materials etc. Hence the need to try and get through at the 'Ledge' dig, as it would have meant bypassing all the vertical stuff and dropping straight in. But that sadly was a no-go too, at least for now. The short level heading east from halfway down Butch Pitch may have been the best approach, but other things got in the way, and haven't yet got out of the way.
I doubt I'll have time for JH when the restrictions are lifted as we've got some far more pressing issues to resolve not too far away, but I'm sure there will be plenty who will.
