Here's a new thought before the usual Sunday evening wine overdose beffudles me completely. Anyone interested in this from the last RNS metallurgy comment; "And identification of any by-products from future production". Had a quick internet search on this and apparently co-elements other than the silver that we know about associated with Lead - Zinc sulphide ores are Ga, Ge, In, Cd, Co, As and Bi. The research paper I was looking at describes these as "Mostly highly valuable, high-tech metals essential in electronics". I could be way off the mark here so caution they may be insignificant in quantity or uneconomic to separate so just a bit of speculation for now but let's see what they do....
