Located on I-70 just 35 minutes west of Denver in Idaho Springs, Colorado

In 1893 construction of the Argo Tunnel Began. It would be 17 years before it would reach Central City , over 4.5 miles away. The tunnel would provide water drainage, ventilation and economical transportation of the gold bearing ore from the many mines it would intersect along the way.

The Argo Mill was constructed to process the gold bearing ore from these mines. When completed, the Argo would be the largest mill of its type in the world. The mill processed over 100 million dollars of gold ore at the old time prices of $18.00 to $35.00 per ounce and stands today as a memorial to the hard rock miners of the day when GOLD WAS KING!
