I might be free that weekend if you want to do a trip. Otherwise the zigzag path is safe except near the bottom where the tide tends to wash debris out from it. If you go partway down the path (where there's a grassy platform) and traverse round the scree along a faint path, you get to a low entrance which opens up into a level with daylight just above. Straight ahead goes to Contact Shaft, with a few short older workings off to the left, and a level on the right about half way along leads via a rise (usually with bats) to a short drop into the big stope with its switchback floor: impressive. You can get to the end to where there's a crumbly climb up and a pitch down but there's not much beyond that point. In the opposite direction a couple of scrambles lead into a lower level which heads back below what you've already done and enters a passage which again leads to Contact Shaft in one direction and the beach in the other. This is where the return back up to the top of the cliffs might be a bit iffy at the start but it was ok the last time I was down there.
