A bankable feasibility study (BFS) into the Superior Lake base metals project, in Canada, has estimated that an initial capital investment of $86-million would be required to develop the 325 000 t/y operation.
ASX-listed Superior Lake Resources on Wednesday reported that over the estimated nine-year mine life, the project would produce some 38 000 t/y of contained zinc and 1 400 t/y of contained copper at C1 costs of $0.35/lb of zinc.
