RE:3rd highest grade Oxide deposit in Americas?Where did you get your facts. I looked it up. Omai is not and has never been and oxide deposit. They used a conventional mill in the past and will have to again. Omai is a sulphide deposit. The deposit is not heap leach (maybe a small portion can be in the saprolite). The mining and milling will require diesel fuel. Plus I am not sure anyone would want a heap leach pad right next to a major river.
