Synclinal fold forms the major structural feature and is manifested as an asymmetric syncline whose axis trends N 15° W, with a general plunge of 10 12° north.

Summary:
Target 3 shaft is currently on care and maintenance and serves as a second escape way for Target 1.
At Target 3 Shaft there remains a mix of remnant ore blocks including shaft pillar blocks where scattered mining can be exploited, and a number of areas of virgin ground where conventional mining can take place, with the potential to exploit zone 3 in the Freddies 9 Shaft area.
During fiscal 2015 the operation was placed on care and maintenance. This decision was taken based on the financial performance of the operation and the future capital that was required to extend the life of the mine.
