This mine was taken over by the railroad, and operated for 30 years.

The mine was operated as a tourist destination from the 1950s to the 1970s.

After 1855, the mine was operated sporadically for a number of years.

More than 100 mines are operated in the area.

Reports on discovery of new gold veins in mines operated by the company were not published.
