A definitive feasibility study (DFS) into the Orokolo Bay industrial sands project, in Papua New Guinea, has estimated that the project would require a capital investment of $20.48-million. Project owner Mayur Resources on Friday said that the DFS estimated that the project would generate revenues of some $969-million over a mine life of 15 years, producing 400 000 t/y of vanadium titano-magnetite, 100 000 t/y of magnetite for dense media separation, 8 000 t/y of zircon concentrate and 1-million tonnes a year of silica construction sand.
