All sounds very reasonable, its an after in-production expense ( with cashflow ) in my eyes even if it has decent upfront capex if it meaninfully reduces opex with this multi-generational mine life its probably worth it.
Even a few dollars extra margin on a high volume item like potash should be well worth it.
Getting a bit ahead of myself, first thing first into finance & construction we must go.
