Mining operations began in the early 1870s and expanded through multiple phases of deep tunneling, technological milling advancements, and recovery from significant setbacks such as the famous 1978 Lake Emma disaster, ultimately operating as one of the region's most productive and enduring lode mines before closing permanently in the early 1990s.
