Notable Finds

Doubly terminated prismatic crystals with stepped faces were found in the second oxidation zone in 1973, almost certainly on 28 Level (Key, 1977). Green, twinned, tabular, pseudo-hexagonal plates of bayldonite were found in the second oxidation zone in 1980. Pseudo-rhombohedral crystal are also noted (Von Bezing et al., 2014).
