Hi,
The paperback version costs £15 new. (£90 second-hand ! )
Wikipedia reports the VERY high concentration of copper salts in the adit discharge water.
Way back in the '70s, when I lived in England, there was a project at Devon Great Consols, to put scrap iron in the discharge to capture copper.....
Anyone have any news on that ?
Regards,
D.Send.
