ABSTRACT
The quotation with which the Introduction to this Part began ought to be kept in mind in reference to the estimates of future production trends provided here and, in addition, there is the caveat that the gold deposits now mined or expected to be put into production during the next few years represent those deposits expected to be economic at gold prices probably not beyond US$600. At higher average prices for gold than this it may be that more potential sources of production will be considered economic.
