The Lunar abundances roughly track Earth abundance. However, in many cases elements on Earth are concentrated by water chemistry, plate tectonics, the oxygen in the atmosphere, and weathering, over billions of years. In some cases, lunar element extraction will need mass spectrographic separation from undifferentiated rock, rather than ore location and refining. Bad news for some of the rarer materials. |

Beneficiated ore deposits are easy to locate on the moon, you find them under palm trees. :-( |
