Extract

Research into the history of the old mines suggests that two mineralized fissuring systems intersect in central Devon, often carrying commercial ore-bodies. The older of these is the east-west system usually carrying copper, iron, or tin, which has been extensively worked in west Devon, but is less developed on the eastern flank of the Dartmoor granite massif.

The younger north-south series, characterized by its lead and silver ores and baryte is particularly well developed in the Teign valley. This band of mineralization can be traced from the north of Scotland through Brittany and Spain to Algeria. In Devon it appears to be divided into three main fissure bands:

  1. 1. Combe Martin to Plymouth.

  2. 2. North Molton to Spreyton, with a possible extension south of the Dartmoor granite.

  3. 3. Molland to Newton St. Cyres and the Teign valley.
