Here is a small company that was located near Phoenix.  It never really amounted to very much.  However, in its final years, it was owned and controlled by Daniel Brockway,  one of the earliest pioneers of the Copper Country.  He first came to L'anse in 1843 as a Government blacksmith to the local native tribes.
During this same period, he also was the agent for the Cliff Mine, now a shadow of its early glory days.  Note the village of Clifton, referenced on the memo.
