Note to reader
The text information cannot be guaranteed accurate at this time. The photocopy I have been working off of is not very good. My next visit to the Keeweenaw will include a visit to the MTU Archives where I will attempt to clarify things. I also need to find out why the diagram seems to be missing the launder lines that discharged the tailings into Lake Superior like the ones shown on the site map taken from company reports.
