Thank you.
One thing I remember from several years ago, if not at least a decade ago, was that one of the majors had a major deposit in the South Pacific, a nickel deposit whose mineralogy was rather unique. They were unable to actually get the nickel out of the sulphide ore, at least in any economical way, and possibly even in some physical way. The matrix of the nickel was very different. This was a major technological problem that they were unable to solve.
At this point, knowing that science is not perfect and looking into the future, is there any anticipation that there is going to be a major hurdle that it may not be possible to solve with the general science and engineering that is being looked at? Do we not have specific answers because this is so new, or is there some major question right now that leaves us concerned that we may not be able to get over this hump and get the concentrates and the ores we want?
I realize that's a difficult question, but let me ask for the best guesses from talking with the scientists involved.
