Over the year, our focus was on the safe excavation and preliminary lining of two 7.3-metre diameter shafts. Excavation of both the service shaft and the production shaft was completed by the end of August 2018, at a depth of 1,005 metres and 975 metres respectively. Both shafts reached potash in the Upper and Lower Patience Lake formations during FY2018. Jansen is intended to mine the Lower Patience Lake formation, which lies between 935 metres and 940 metres.
In June 2018, the Board approved further funding to cover support services at the site as work continues on completion of the shafts, updating the approved investment for the current scope of work on the Jansen Potash Project to US$2.7 billion.
