Re: Jansen, all I could find was mention of a 3.37 billion tonne resource - but no grades shown
3.37 billion tonnes, 8 million tonnes per year production and 70 year mine life
"on for the ground freezing process that is required prior to the sinking of the production and service shafts. Based on the current schedule, Jansen is expected to start producing saleable potash from its 3,370 million tonne in-situ Mineral Resource in calendar year 2015."
