Are Treveneague Old Bal and Penberthy Croft one and the same mine? Is Aditnow the only place that mentions Treveneague Old Bal as a mine in its own right (or even as exisitng) or are there other references somewhere.
Penberthy Croft is well written up on the site, is a triple SI and controlled by Marazion estates office but has no photos. Treveneague Old Bal seems to have no write up or records but now has fine pics of an unamed shaft collar.
If they are one and the same can they be combined somehow?
Just curious.
