Western Australian-based minerals company Agrimin has awarded Primero Group an engineering design contract for its Mackay Potash project south of the Port of Wyndham.
Under the early contractor involvement-based agreement, Primero will initially be responsible for the process plant design works at Mackay Potash.
Agrimin considers Primero experienced to undertake both the engineering design and subsequent construction of the process plant and associated site-based non-process infrastructure.
Primero has commenced its engineering design work at the operation.
The process plant has been designed for a capacity of 426,000 tonnes a year of sulphate of potash (SOP) as dry granular product.
Mackay Potash covers 4370 square kilometres spanning Lake Mackay, the world’s largest undeveloped SOP-bearing salt lake, according to Agrimin.
The company plans to extract SOP mineralisation, which is dissolved in the brine within Lake Mackay. Mackay Potash’s products will be sold to domestic customers or exported through the Port of Wyndham.
A prefeasibility study on Mackay Potash shows an initial 20 year operation, with the potential to increase production rates and extend the life of the project.
Agrimin’s process consultants at Novopro Projects have completed the process modelling and flowsheets for Mackay Potash’s definitive feasibility study.
Mackay Potash hosts a specific yield mineral resource of 26.1 million tonnes of SOP to a depth of 30 metres, comprising 10 million tonnes classified as indicated and 16.1 million tonnes classified as inferred.
