Worked from 1846-54, originally as a copper mine, subsequently as an iron mine, the lode consisting mainly of siderite at depth. On the south of the river is the Wheel Pit, the collapsed adit is just west of the dump, remains of the miners 'offices' are north of the dump.

May 2019. On the south bank of the river a leat that delivered to the waterwheel runs about 1/4 mile west to a take off point on the river. At river level on the south bank running east is a high banked ditch, the level bottom and width of which looks like a tramway, but the fact it starts at the wheel and ends back at the river suggests rather it was for water discharge. The shaft is fenced and flooded at river level but the top of a pump rod stands clear of the water 8 to 10 feet to ground level. The dump on the eastern side is comprised of soft grey shale productive in secondary copper minerals. In contrast to the west the tip is predominantly harder rock with a yellow limonitic coat and yields abundant siderite and pyrite.
