Water-ice is plentiful at the lunar poles (probably mixed with regolith).
The lunar soil and rocks contain plenty of iron, aluminum, titanium, silicon & oxygen.
And, also, [by extrapolation and statistics] carbonaceous-chondrite asteroids have hit the moon and deposited plenty of carbon beneath the surface [interest to find out where exactly].
And iron-nickel asteroids have hit the moon too....They would have deposited large
quantities of iridium, platinum, etc...
The moon's resources are more diverse and more plentiful than some flippant responses by some others have indicated.
