Yesterday, BHP announced they were on track to invest another $7.7bn into the second stage of its mammoth potash project based in Canada. The investment is set to double production, making its Jansen potash project one of the world’s largest mines – BHP has to adopt a “get big or get out” approach to the investments; otherwise, it simply won’t move the dial on its earnings profile, the primary reason it hasn’t ventured into lithium. The war between Russia and Ukraine has seen prices double, creating inflation across the food industry, with potash being a core fertiliser for crops such as corn and wheat.
