The ladders in Coad's Shaft are dangerous and it's a rope job.
There is also another shaft open on that patch....I think it's possibly Lark's Shaft.
There were a line of shafts going up towards the horse place (one is still open with a massive cone on it, you can see from the road). I can't remember where I got the information from, but this is East Wheal Damsel. (worked the extention of West Virgin lode). Carharrack mine was on the other side of the road and worked the extention of Wheal Maid South Lode (IIRC). There is a degree of confusion about Whiteworks (behind Drew's yard, now obliterated) being a part of Carharrack Mine, but this is erroneous IMO. Whiteworks being a separate venture dating back a serious long time. I think Henwood (1843) refers to it being ancient.
If you're interested in that area, the best thing you can do is go to the County Record Office and ask to see MRO-R103 which are the consols/united plan bunch. They are the best of the Cornish Mine Plans, which as a whole are some pretty impressive documents.
Consols really pushed the boat out and some of them are like paintings.
