The Badminton records at the National Library of Wales contain a number of
leases of calamine, lead, copper & tin in the Wastes of Crickhowel anmd
Tretower (nr Abergavenny), eg dated 1737.
Is anyone aware of any actual mining in this area?
The geological memoirs refer to quite common barytes mineralisation in the
Carboniferous Limestone in the area, and cave exploration in the Blorenge
area further south in the last 15 years has revealed extensive barytes
mineralisation with spectacular secondary copper deposits, but I have seen
no evidence that this was ever worked.
It of course lies just on the edge of the South Wales coalfield, & there
is much documentation of coal & ironstone mining from an early period in
