Hundreds of tiny hexagonal prisms of #Mimetite (looking a bit like insect eggs). A secondary mineral that forms with exposure of galena to sea water.

Given the time span involved, these would have formed long before it was mined and fell onto the beach, so it presumably originally comes from where they followed the galena ore vein underneath the sea.

This small mine was abandoned in 1858 due to sea water entering from a crosscut which intersected the workings.
