Jochen: Thanks for your post, and you are right about the Croffut's listing. Poors first book also mentions Saxonia, but ironically, both of them got it wrong. The neal name of the company was the Saxonia Mining and Reduction Company. I believe I have discovered where the error started. I've seen the original deed and map attached, and when the Jefferson County officials made a file copy, March 17, 1880, in pen and ink and by hand, the copy person accidently changed the word from reduction, to refining. Interesting. Saxonia used the Pattinsen process for lead reduction or purification...as well as the more common mineral extraction processes. In those days before the EPA...lead production was very big and profitable business. Thanks. "Bo"
