Mines That Weren't Quite

My purpose here today is to introduce an element of democracy into this seminar. In my experience, the mines of Australia can be divided into two categories; those that pay and those that don't. As far as I can ascertain, every other paper being delivered at this seminar concerns mines which come into the first category, or at any rate are close enough to it for the promoters to be able to afford an expert's valuation.
