Historical note

In 1850, the Adventure Mining Company (unrelated to present company) was formed and operated a mine until 1862. In 1863, it was purchased by Thomas Mason and named the Adventure Copper Company. Starting in 1898, the property was operated by the Adventure Consolidated Copper Company. Production ceased in 1908 due to low copper prices, but restarted for a short time during World War I. Production finally halted in 1917 and the mine closed in 1920.

Beginning in the 1970s, tours have been available on and off. Jack and Margaret Neph purchased the mine in 1972 and offered tours from 1973 through the mid 1980s. Their son John, along with his wife Winnie, offered tours from the late 1990s until 2003. The current owners, the modern Adventure Mining Company owned by Matthew and Victoria Portfleet, purchased the mine in 2004 and have operated tours since 2005.

Since 2009, an annual bike race called Miner's Revenge has been held whose course runs both within the mine and above ground.
