The earliest documented record of mining at Gunnislake Clitters dates to the 1820s. However, mining was probably going on long before, and within Clitters Wood there are many shafts, trial pits and trenches providing evidence of 18th century or earlier operations.
Between 1820 and 1920, Gunnislake Clitters Mine was worked for copper, tin, arsenic and wolfram (an ore containing tungsten). Clitters processed mundic from Devon Great Consols in the early 1900s, but eventually defaulted on a payment for 200 tons and consequently closed its operations (1)
