Anybody on the list know what the annual average £Sterling price per ton
(“long ton”) of copper metal has been since 1976 to date; or know where I
can get that information without having to pay exorbitant subscriptions to
specialist web sites? I need this information in connection with current
research into two historic copper mining districts in Ireland.
Thanks if you can help,
