You are probably correct about that. So, assuming that at some futire date, someone, probably a mining company, will commence operations there, (now here I am assuming that the problems of a self sustaining colony are solved) the question I have is--are there any minerals on the moon worth going after? What is the potential for gold, for example? I don't think there is any oil there of course, :) but why wouldn't the expectation to find precious metals and jems be as good as it is here on Earth, albiet conditions a little harder to work in? Also, since we know that deep mines on Earth are hot, because we are getting closer to the molten core of the Earth, would that same thing occure on the moon? :)
