We recently teamed up with @ABANDONED_UNDERGROUND , @AbandonedMines11 , @ZiaMountainAdventures , and @OnTheNextEpisode to explore and document this Arizona polymetallic mine. Discovered in the 1880s and worked on and off through the 1950s with suspected exploration work into the 1970s, it is accessed via three haulage levels, one of which is reported to punch all the way through to the other side of the mountain. Does it still? Stay tuned to find out!
