A prefeasibility study (PFS) into the Butcherbird manganese project, in Western Australia, has identified a start-up manganese concentrate export scenario as part of a staged development strategy.
ASX-listed Element 25 on Tuesday said that the base case assumed an annual production of 312 000 t/y of medium-grade ump manganese concentrate, grading between 30% to 35% manganese, over a mine life of 42 years.
