There was certainly discussion about this at an interdisciplinary conference I went to in Nenthead, Cumbria a couple of years back organised by Peter Claughton, where it was discussed as a possible explanation for the historical interest in the Cumbrian mines and their putative productivity asd stated by Ian Blanchard. The geologists said that there was no evidence from their streambed alluvium studies that there were ever veins of sufficiently high silver content to justify these productivity claims and I was inclined to believe them. Others were rather more forthright in the matter.There again many academics may have based their work on Blanchard's studies and will hold opposing views.

I think that I remember a discussion in the list some time back about the possibility that some lead ores found near the surface could have or had a higher silver content than is now believed to have been the case. If my memory is correct does anyone know if there have been any developments with this research.
