The original version of this article unfortunately contains a mistake in the Chapter “Extrapolating with the help of the semi-logarithmic Lasky’s relationship” in the first bullet point: Singer’s (2017) estimate of 6.4 GT Cu does not contain past production. The correct bullet point has to read now:

  • One example is Singer’s (2017) estimate of 6.4 GT Cu. The method Singer (2017) used relied on global probabilistic estimates of the number of undiscovered deposits (not now known) by deposit type and the distribution of contained copper in each deposit type (4.3 GT Cu). To this number was added known reserves of each deposit type for a total of 6.4 GT Cu.
