Actually Noront was looking at the Kidd smelter a while back but the KWG railway to Aroland? issue diverted their attention ( slurry pipe and all). The reason they looked at it was that there would have been nominal costs with its activation and the labour force is well trained and available in place.

For chromite, no matter where all the prcessing plants would be, would have to be mostly built. Even an existing facility from other metals would have to have extensive modifications and extentions. Chromite processing is more akin to aluminum then any other metal.
That is the sum of my know how.
