@TomFerry and I have been inside some of the wetter parts of it. There’s some fantastic stempling inside plus and a ladder or two. I recall some beautifully formed ochre steps and a place to hang tools. There are a few shafts/trials listed much higher up the incline that I have not explored. I’m sure Tom might have some pics as I don’t have any to hand right now.
There are other workings that I believe are the same mine below the road, including a deep adit, but when I explored it was run before it reached the stope.
