I've been in the investment world a long time and I know that things can
stay below the cost of production for years. It takes a long time for
people to believe they have to close their mines. It costs money to
close a mine, it costs money to re-open a mine, so people are reluctant
to close mines. So you can see any commodity staying below the cost of
production for a while, especially if it's something like a mine which
is expensive to close, and expensive to open.
