Copper/Lead (18th century/1848-1880)

A single east-west striking lode with galena and chalcopyrite mineralisation in Silurian Gwestyn formation shales. The dominant gangue mineral is calcite.

There is a deep adit at SN86008770, an upper level at SN86398768 and a shaft at SN86108662.

There are the usual earthwork remains of tramway track beds.

No evidence.

There are three wheelpits deeply buried in collapsed material and hidden by forestry. The largest of these was the pumping wheel which drained the shaft and measured 46x4.5ft. The other two drove a small crusher/stonebreaker and the last drove the round buddle. There is plenty of evidence for jiggers in the form of tailings heaps.
