Notable Finds

Reinerite (type specimen) was discovered approximately 10 m below 29 Level, in the second oxidation zone in 1958. In 1977, Reinerite was again found in the second oxidation zone by Georg Gebhard, with a new mineral that would later be named gebhardite. Excellent crystals of reinerite were found in 1992 in the so-called "Zinc Pocket" on 44 Level, in the third oxidation zone (Gebhard, 1999).
