The Argo Mill was completed in the early 1900s, soon after the 10-year Argo Tunnel operation was completed. In its time, the state-of-the-art milling techniques of the Argo processed over $100 million worth of gold ore!. The prices per ounce ranged from $18 to $35, meaning the mill operations were hard at work each and every day.
