Now, about the overall content of the moon.

Free metal concentrations in stony meteorites are about 20%, compared
to a few hundred ppm in the lunar regolith. M-type asteroids are about
99% metal. C-type asteroids have 5% to 20% water. The lunar surface,
by contrast, has no native water. Solar wind implantation of hydrogen
on the lunar surface offers up to about 50 ppm hydrogen, which, if
fully released and fully converted into water, would optimistically
give the lunar surface about 0.045% water. Overall, the lunar surface
is volatile-poor and metal-poor.

Oxygen yes, but Oxygen is near zilch.

But find a good crater and maybe you'll have an oasis of sorts.
