Spanish potash developer Highfield Resources has completed a scoping study for a staged 500 000 t/y sulphate of potash (SoP) operation by converting 430 000 t/y of muriate of potash (MoP) from the Muga potash mine.
Total capital expenditure (capex) for the operation was estimated at $147-million, with preproduction capital estimated at less than $100-million for the first phase of 250 000 t/y, the ASX-listed company reported on Thursday.
