I was more referring to this language from the BMO report:

At a 10% cut-off, the resource is 6.7 million tonnes indicated (24.2% P2O5 and 5.63%

iron/aluminum), and 8.3 million tonnes inferred. Note that 3–4% iron/aluminum is an

often-cited industry benchmark for feasible phosphoric acid manufacture).

I'm not familiar with the technicalities of phosphoric acid manufacturing, but this seems pretty clear. The typical cutoff of iron/aluminum content for phosphoric acid production is well below the ore that Legend will produce. So my questions are if the new big plan is to go into such a manufacturing process what extra costs are will be incurred, is it feasible at all, will the end product be less desirable and thus less profitable that a similar operation elsewhere?
