Actually, these numbers are derived from the current best estimates of the average occurence of the elements in real Lunar regolith. And with the meteorites delivering gold as well, it seems to work out well enough at this production rate. We are constantly keeping an eye on things, though, and may end up reworking the numbers at some point.
