I thot it was grade not metallurgy that stopped that one. The Dunka Road deposit when Fleck had it. I knew about it in the late 1980's but Fleck who got it off Anaconda could not finance as the whole copper-nickel low grade market back then was strictly a major thingie and not much of that. Teck pawed at it and turned up its nose. One of the keys to these kind of deposits is what do you do with your concentrate. If you have the kind of mill Polymet contemplates then you can do back end processing, as in the Sherrit process. If you nickel is not too much tied up in pyrrhotite. I am not sure how much pyrrhotite ties up nickel these days in the ammonia type processes. polymetmining.com
