Summary

Gill's Shaft, one of seven shafts recorded at Wheal Crebor copper mine, and shown on 19th century maps. A spoil heap and the earthwork pit of the possible shaft were transcribed as part of the NMP survey of the Tamar Valley AONB. A curvilinear bank is visible as an earthwork on visualisations derived from lidar data captured 2010 and 2013.

A curvilinear bank, circa 45 metres across, is visible as an earthwork on visualisations derived from lidar data captured 2010 and 2013.
The visible bank closely corresponds with an earthwork depicted and labelled as ‘Gill’s Shaft’ on the late 19th century First Edition Ordnance Survey map. It has not, therefore, been transcribed during this survey.
