Work is part of the pre-feasibility study (PFS) work underway.
The optimised process flowsheet will form the basis of process design, equipment selection and equipment sizing, and should reduce both capital and operating costs for the project.
The flowsheet has relatively straightforward processing design parameters using a number of regular processing items and equipment.
FYI’s managing director Roland Hill said: “Attaining the excellent base grade of 99.997% HPA is a remarkable achievement and a testament to the efficiency and effectiveness of the Cadoux process flowsheet.
“The company’s focus is on building a quality HPA strategy as well as delivering a superior investment return to shareholders – so operating margins and capital costs are important to our business case.
“We expect our extensive defining test work program and resulting flow sheet optimisation to bear fruit for us by having a material impact on the project economics.”
