A series of spoil heaps line up roughly east to west on the south side of a very shallow valley. The waste material is primarily very soft pale grey mudstone. Metal ores are relatively uncommon. Several piles of rocks presumably ploughed out of the adjacent fields have been placed on what were presumably shaft collars. Oct 2025.
