Tavy and Tamar Valleys (Devon side) - Lodes 28-30

Lode 28 - Ding Dong Lode

The deep adit of this ancient working discharges into the Tamar 120m south of New Bridge. At least two shafts are known on the line of the lode and a clump of trees in the fields to the east of Dyer's Shaft may be the site of another. Dyer's Shaft was certainly in existence by 1815 and its crookedness may imply a much earlier origin. It was used for accessing the mine during prospecting in the 1980s via an electric winch mounted on a steel headframe, which survives over the open, though gridded shaft.

The method of pumping in the 18th and 19th centuries is not known, although a leat was brought from Impham Valley to the vicinity of Hatchwood House which lies on the lode, probably in the 18th century or even earlier. The upper and lower channels of the Bedford United Leat cross the lode further down the hill, suggesting that there may have been a pumping water wheel at some point from 1842 onwards when this part of the leat was cut.

Lodes 29 & 29a - New Bridge Lode & unknown, Bedford United Mine

It is not known when underground working commenced here, but by the later 19th century McCallan's Shaft had been sunk, being pumped from a beam engine on the Marquis Lode at Bedford United Mine to the north via a 400m run of flatrods. A substantial dump survives here, although the shaft has been capped.

A short adit on a lode cut by the Mill Hill branch of the Tavistock Canal may be on this lode, which never seems to have produced any worthwhile ore.

Lode 30 - Delves Kitchen Lode

It is not known when underground working on this lode commenced, but its principal engine shaft lies 200m north-west of Gulworthy Cottages and remains open, with a strong stream of water emerging from its pump lobby a short distance to the west. A further fenced shaft lies in fields 180m west of Gulworthy Farm. This lode was worked in the later 19th century as part of Bedford United Mine.
