  • 1st Oxidation Zone
  • 2nd Oxidation Zone

Notable Finds

The type specimen is from 7 Level, in the first oxidation zone. In the second oxidation zone, a schultenite pocket was found on 28 Level during 1975, with crystals mainly < 10 mm but exceptionally to 40 mm, and associated with cuprian adamite and keyite. In early 1980, the largest recorded schultenite crystal - 175 mm in length - was recovered from the north-east stope on 35 Level (Keller and Bartelke, 1982). (Note that Von Bezing et al. (2014) suggest that this large crystal also came from the 28 Level discovery.)
