RE:RE:RE:Giga Metals is the FUTURE!! Invest now!!First of all, Giga Metals has a sulphide deposit in northern BC and you do not treat suphides via HPAL or PAL. The standard flowsheet is a crushing/grinding/froth flotation circuit to produce a nickel concentrate. It would not be a mixed suphide.
Second, Sherritt's refinery stopped buying third party feed a long time ago. It is better for them to treat the mixed sulphides from Cuba alone.
Finally, this project will never get off the ground. It is a low grade deposit and there are better ones around the world operating.
