[6] The property was closed in January 1943 after a major hydraulic accident in the tunnel, and never reopened after a federal moratorium was placed on gold mining during World War II.

In 1976 it was purchased by a local investment group led by James N. Maxwell, who wanted to preserve an example of the Colorado gold rush mines.

It was renovated and reopened as a tourist attraction and mining museum, and presently continues to offer daily tours.

Visitors are provided with a brief history movie, an ore sample and mining equipment demonstration, a tour of the now-reopened tunnel entrance, and a descending tour of the mill structure and extant equipment including gravity separators, amalgamation trays, and froth flotation cells.

An outdoor museum, partly visible from the street, includes larger period equipment used in various stages of extraction, separation, and smelting.
