Much of my NAMHO Conference Talk (the Conference served the best Conference catering I have ever been to) has been published as "A mineralogical and historical evaluation of lead ore from Sark's Hope Mine" in Report and Transactions of La Societe Guernesiaise, vol XXIV, 2000, 856-861. If anyone who is not a member of the La Societe, and has an interested in detailed mineralogy and mine records can be used to speculate on mining history, would like a copy, please let me know and I'll send a reprint.
