About the Edgar Mine

The Experimental Mine is located in Idaho Springs, Clear Creek County, Colorado. Originally known as the Edgar Mine, it was an active producer of silver and gold, with some lead and copper, in the 1870s. The Mine passed through a number of hands before being purchased by the Big Five Mining Company.

Big Five leased the Mine to the Colorado School of Mines for training purposes in 1921. The School of Mines eventually acquired the property and surrounding properties for use as an underground classroom for engineering education and as a research facility. The Mine has also been used to train outside groups in mine rescue techniques and disaster preparedness.

The Edgar's workings include the Miami Tunnel, Edgar shaft (which follows the original Edgar vein), and the Big Five Tunnel. The Edgar and associated properties have been included in the Idaho [Idaho Springs] and Spanish Bar mining districts.
