In a petition dated 1688 Richard Strode, of Newnham claimed ownership of tinworks called Owlacombe Beam within Ashburton stannery.
The Owlacombe set was worked in recent times as lode workings and produced 348 tons of black tin up to 1909.

(Visited 20/5/1960) A considerable area, centred at SX 7685 7335, in which are overgrown tips, shafts and ruined buildings associated with the tin working. The buildings are modern and nothing of the 17th century industry is identifiable.

Owlacombe covers an area which includes a number of separate ventures latterly brought together under the name of Ashburton United Mines, and worked in conjunction with Stormsdown to the south. The mines were active, mainly in the southern section, during the early part of the 19th century, but closed in 1866. In 1906 the mine was taken over by a South African mining engineer who installed new machinery on South African lines. There followed a period of considerable activity, until about 1912, during which up to 200 men were employed, some from as far away as Tavistoc, working an eight-hour shift system. The business was not, however, very profitable, and more money was made from arsnic than from tin, of which there was a total recorded production of 348 tons. The mine was later worked for a time after 1930.
Situated between Ashburton and Ilsington, considerable remains can be seen on the rising ground south-east of the Owlacombe Cross-Sigford road. A number of shafts are visible, as is the course of the tramway, thickly overgrown with bracken, although still traceable. The tramway worked on a system of pulleys and chains and conveyed material from the shafts to the refining areas. Though largely demolished, the position of the stamps and stepped dressing floors can be seen, as well as the position of the buddles. There are also the remains of the buildings where the ore was calcined and arsnic condensed, while in 1966 the brick stack which formerly discharged fumes from these was still intact, though likely to be demolished by the owner before long (see plate). This stack, about 30 feet in height, was built early in the 20trh century.
Power was supplied latterly by electricity generated by a producer-gas engine using coal. Some remains of the power house and generator house still exist, though much of the brickwork on the site is undergoing demolition, the bricks being put to other uses. There are also a few remaining cottages which formerly housed some of the mine workers.

There are six deserted buildings visible in this area, all presumably associated with the mine.
