Tiny underground working with chambering.** - AJR Summary
In the main workings a wet adit leads to an open chamber. Above and slightly to the south west another adit leads to a level that comes out higher up in the same open chamber. In the chamber there is a lot of fallen rock and this rock has obscured and flooded a level to neck deep heading further inby so this has remained unexplored. Two other levels away from the main site remain unexplored with the level next to the river gated and locked. - Blober
