According to http://www.uic.com.au/nip75.htm, the average amount of Uranium in the earth's crust is 2.8ppm or 0.00028 percent. So one would never attempt to crush ore at 0.00005 percent, because that is less concentrated than the average piece of crust.

From World Uranium Resources, by Kenneth S. Deffeyes and Ian D. MacGregor, Scientific American, January, 1980, page 66, it is estimated that for a ten times increase in price, the supply of uranium that can be economically mined is increased 300 times.
