There has been some confusion between this and an old site called 940. There
appears to be only one shaft in the area.
The slab covered entrance is marked M50 with green paint. A 27m descent drops to a large ledge and then 8m to a choked floor. A small hole on the opposite side of the ledge at -27m may repay some digging. (Note that site 319 also has the SEAD M50 label)
