An updated feasibility study (FS) into the Citronen zinc-lead project, in northern Greenland, has estimated that a capital investment of $514-million would be required to support the 3.3-million-tonne-a-year operation.
With a production rate of up to 200 000 t/y of zinc metal and a mine life of 14 years, the Citronen project was expected to generate life-of-mine revenues of some $6.36-billion, ASX-listed Ironbark Zinc said on Tuesday.
