The project is fully permitted following the signing of a mining agreement, and the subsequent award of the requisite mining licences in early 2017.
A 2015 feasibility study estimated that the Stage 1 development of Colluli will require a capital investment of $442-million. The study examined a two-module development with an expected production of 425 000 t/y of sulphate potash for the first five years of operation, increasing to 850 000 t/y for the remainder of the proposed 30-year mine life.
