Notable Finds
As spectacular pseudomorphs after mimetite in the upper levels of the mine (many of which were originally considered to be bayldonite after mimetite). In 1989 fine specimens of azurite on arsentsumebite were recovered during pillar-robbing operations on 6 Level (Von Bezing et al., 2014). Many azurites from the famous "Easter Pocket", recovered from 8 Level in 1994, are associated with arsentsumebite.
