Apparently gravimetry has revealed an anomalous mass of about 1.3 x 10^18 kg beneath the South Pole-Aitken Basin, a 4 billion year-old impact crater near the south pole of the moon.  They believe it is a metal (i.e., Nickel-Iron) meteorite buried after the impact.  Such Fe-Ni meteorites often also contain high concentrations of cobalt and platinum-group metals. Unfortunately, it appears to be buried in the mantle.  Unfortunately, the mass appears to be located in the Moon's mantle, rather than its crust, so it doesn't seem exploitable.

  • Ignorance can be cured. Stupidity, you deal with.

The moons mantle is mostly solid, so the things that limit mining depth on Earth won't apply there in the same way.

OTOH deeeeeeep digging is gonna be expensive and difficult. The abstract says the mass extends 300km down, but not the depth where it starts.

I am aware that the Moon’s mantle is not liquid; the depth of the deposit is why I suspect it is not exploitable.
