Focus in FY2020 was on safely installing new work platforms, called Galloways, into the two 7.3-metre diameter service and production shafts to enable the installation of the final watertight composite concrete and steel liners from a depth of approximately 900 metres. At the end of FY2020, the current scope of work was 86 per cent complete.
The service shaft and production shaft are 1,005 metres and 975 metres deep, respectively. Jansen is intended to mine the Lower Patience Lake potash formation, which lies between 935 metres and 940 metres.
