A scoping study into ASX-listed Caravel Minerals’ copper project, in Western Australia, has shown that the project could generate revenues of A$10.6-billion and free cash flow of A$3.1-billion over a 23-year mine life. The scoping study estimated that a capital investment of A$481-million would be required to develop an initial 16-million-tonne-a-year operation, which would ramp up to 30-million tonnes a year from year six.
