Excellent. As it stands after 2022, Glencore's Mt Isa smelter stops operating and they stop producing sulphuric acid as a by-product for Intec Pivot's phosphoric acid plant at Phosphate Hill. There have also been indications that the smelter may be shut earlier due to high power costs in QLD. Intec Pivot will need to look at other options if they want to keep their fertilizer plant operating.

Slide 19 of the presentations show other phosphate projects which may also be options and could potentially be a JV option. The price for Phosphoric acid on the slide they mention is A$820/mt.


This doesn't take into account other Cu oxide SXEW plants that may reappear once the copper price is high enough which will also need sulphuric acid (Lady Annie & White Range were the two in the region that were previously in operation from memory)
