Going right at the main junction leads to a massive chamber that has somehow been filled with rubble (either from above or carried in on tracks I presume?) Appeared to be some asbestos waste also so take care.
One area I need to check out is beyond the crawl near where the old car is, it seems to lead to a fairly large area of the mine with a rope in situ to descend somewhere.
Would love to join you but work commitments mean a no go most Thursdays :thumbdown:
Have fun :thumbsup:
