Alluvial tin streamwork near the Brim Brook

Historic England's scheduling record (list entry 1018928) describes an alluvial tin streamwork beside the Brim Brook, with well-preserved earthworks that point to several phases of working. Most of the waste dumps lie at right angles to the valley bottom, and many are held up on their north, upstream side by drystone walling. Three separate blocks of this type are visible, each served by a well-preserved leat. In the north a few narrow banks parallel with the brook may be more recent dumps. It lies in the parish of Dartmoor Forest, about 0.7 km south-east of Dinger Tor.

Three rectangular buildings used by the tinners for shelter and storage are cut into earlier waste dumps. The northernmost is 5.2 metres by 3.2 metres inside, in two rooms, with a drystone wall 1.5 metres wide and up to 1.3 metres high. The central is 4.8 metres by 2.1 metres inside, with a wall 1.9 metres wide and up to 1.1 metres high. The southern is much larger, 8.6 metres by 3.5 metres inside.
