2 possible adits mentioned in CaMoA following personal comms with Harold Morris:

Adit C’ NGR SH 4080 9456 and Adit D’ 4066 9440 Two adits can be seen from the old silica brickworks, in the cliffs at the other side of the bay. Not visited. Adit ‘C’ is high in the face of a vertical looking cliff, and would be very difficult to access, requiring a descent from the top using ladders or SRT. Adit ‘D’ is in a fairly low cliff just above high water mark. Warrants inspection.
