As part of the initial stage of a new and exciting Conservation Management Plan for Okel Tor Mine, a drone survey has been conducted producing spectacular 3D images of the mine. This survey will inform works to stabilise the structures and help guide the future management of the site.
Okel Tor is a 19th century mine producing arsenic and copper with significant quantities of tin and some lead, located across the north bank of a loop in the River Tamar east of Calstock in south east Cornwall. The earliest recorded working at the mine involved an adit dug from near the riverbank in about 1845, producing arsenic and copper ore.
More information on the site may be found on the Historic England website (https://historicengland.org.uk/listing/the-list/list-entry/1019440)
Okel Tor lies within both the Tamar Valley Area of Outstanding Natural Beauty (Tamar Valley AONB) and Area 10 of the Cornwall and West Devon Mining World Heritage Site – the Tamar Valley Mining District with Tavistock. The Tamar Valley AONB is a nationally important designation supported by a wide Partnership and a small team that produces a statutory Management Plan every 5 years to conserve and enhance one of our best national landscapes, whilst recognising the needs of the local community and economy. In relation to the Cornwall and West Devon Mining World Heritage Site, which is an internationally important designation from UNESCO, Okel Tor is a principal site within the Tamar Valley. This area (which has the same UNESCO designation as Machu Picchu and the Galapagos Islands) includes Devon Great Consols, Mowellham Quay and Tavistock, and also overlaps the Tamar Valley AONB with the rich mining landscape being an important characteristic of both designations. Okel Tor Mine is also a Scheduled Monument and the mine buildings are Grade II listed.
Theproject is being grant funded by Historic England who will be monitoring the work with the enthusiastic support of the owners of the site. The work is being carried out as part of the creation of a Conservation Management Plan which will look to help remove the site from the Heritage at Risk register . The survey is required to be at a level of detail and accuracy to allow the condition surveyor to zoom in to identify any problems with the structures (particularly the wall tops and the chimneys) not visible from the ground without the need for expensive scaffolding. The work will help in the drawing up of a schedule of works for the ongoing protection of the site. This work is vital and will be used to secure and protect this beautiful and culturally significant site for future generations. An added benefit of the survey is the creation of the 3D images which show the mine as it has never been seen before.
The next phase of the project will be assessing the results of the survey and creating the Conservation Management Plan. This way the delicate task of the conservation work needed can be carried out in the upcoming years to keep this key piece of history stable for the future.
The images produced can be viewed below, it should be noted they are large so could run slowly.
