Mining in Cornwall and Devon

Mining in Cornwall and Devon in the south west of England began in the early Bronze Age approximately 2150 BC and ended with the closure of South Crofty tin mine in Cornwall in 1998. Tin and later also copper were the most productive of the metals extracted: some tin mining continued long after mining of other metals had become unprofitable.Historically extensive tin and copper mining has occurred in Cornwall and Devon, as well as arsenic, silver, zinc and a few other metals. As of 2007 there are no active metalliferous mines remaining. However, tin deposits still exist in Cornwall, and there is talk of reopening South Crofty tin mine. Furthermore, work has commenced to re-open the Hemerdon tungsten and tin mine in south-west Devon. Geological studies were made worthwhile due to the economic importance of mines and quarries: about forty distinct minerals have been identified from type localities in Cornwall, e.g. endellionite from St Endellion. Quarrying of the igneous and metamorphic rocks has also been a significant industry: in recent times the extraction of kaolin has been the most important economically.
