A number of tin lodes were developed in the Runnaford Combe Mine, on the north bank of the Mardle at Coombe Bridge. Originally worked as an opencast 100x50 yards and 50 feet deep, the lodes were subsequently worked from at least two shafts.

In 1848 the mine was said to be producing more ore than the 14 head of stamps could process. A year later, 12 more stamps were added and an engine house constructed, but the engine not being entirely satisfactory, it was later replaced by a waterwheel.

Work was suspended in 1853, when attempts were made to re-float the Company with increased capital.

A Chimney, shown on old maps, was felled in 1915 and, falling nearly intact, could recently be seen in the garden of a nearby cottage (HJ 1981)

In describing the mine, Hamilton Jenkin noted that a specimen of the ore in his possession showed the tin to be of excellent quality and notable for its fine crystals.

Spoil heap. Copper.
