Wrentnall Barytes Mine
The Wrentnall barytes mine operated between 1890 and 1925 producing a total output over this period of 29,206 tons of barytes, mostly form beneath Broom Hill. Most of the working was carried out using drifts and there is little evidence of deep shafts or any headframes.
To the west of the road is a filled shaft and an adjacent filled stopehead. Further west is an adit in a cutting which has been dammed as a water supply. East of the road, next to the footpath, is a collapsed shaft and a collapsed associated adit. South of the stream, two adits have collapsed. Further south-west is a drainage adit which has collapsed but is issuing water.North of the stream is a line of three flooded shafts and a shallow grilled shaft which has not been explored. Higher up the hillside is a large opencut working with a short adit exiting the eastern end. Sited here was the processing mill, with part of the wall and the machinery footings still visible. East of this is another flooded shaft with an inclined tramway heading up the hillside to a loop which ends at a collapsed adit. This connected through to a large open working and the other entrance is still open. It also recently caused a subsidence in the track above. The passage heads south-west for a short distance to where it has collapsed, leaving it open to surface. East of here is a filled shaft and an open shaft which is 18ft deep to water. In the valley bottom is a collapsed drainage level which still issues water.
