Hi Zac,
A warm welcome to Adit Now!
I can help you with this query, as we visited back in 2005. I took a number of pictures(slides), both surface & underground.
We descended two shafts, one adjacent to the minor road(Castleton to Pindale) and there is another shaft in garden of cottage in Pin Dale. I have some details of our explorations, on my word processor!, which I would be pleased to send to you. If you could drop me a pm.
Cheers,
Paul.
