I have found the entrance by the WW2 pillbox on a previous visit, and am keen for a trip into the aforementioned mine.I shall be down on hols 2nd week in Sept, would anyone be up for a trundle that week ?

If you've got a spare lamp I probably would be.  Send me a PM.

Twiglet and I had a look at it.  There's a scramble up through undergrowth from the beach and a traverse through similar to get into the entrance.  The adit is about 500ft long with a shaft from surface which is vertical then descends on the dip of the lode and continues below the adit but is flooded.  There's no stoping, the lode looks very thin, but there are a few ochre stals and some pretty sections of copper staining

And it's also the first time I've seen a rat in a mine.
