Hi Bill,
Interesting, good luck with it. Simon may be right about "unlimited" resources
actually existing, but it may be more a matter of semantics rather than
existing in the meaning of being available, which I guess is much of your
premise (hope that mades sense).
Be careful with that "good data" you quote of mine above. First, either you
missquoted it or I made a typo. That should be as low as 0.03 ounces now. Most
of these new low grade open pit gold mines can mine at 0.1 ounce and as low as
0.03 ounces per ton (as in around $10-11 per ton value), and there are a few
down below that. Also, the figure of around a half ounce up to about the 1950s
is very general. It depends on the decade (war time, worldwide recession,
etc.), as well as a lot of economic factors.
