Or even the Moon

  Not terribly useful ones, though. The available metals on the moon are largely just silicon, aluminum, iron, magnesium, and titanium -- much like on Earth. https://sites.wustl.edu/meteoritesite/items/the-chemical-composition-of-lunar-soil/ https://sites.wustl.edu/meteoritesite/items/the-chemical-com... Asteroids are more interesting because they contain high concentrations of slightly denser metals of considerably more interest -- nickel, cobalt, etc. They can also contain much higher than normal concentrations of very heavy metals -- iridium, platinum, etc. -- that are rare in the Earth's crust because they're so heavy they tended to migrate to the core!

    Just a note. They migrated to the core because they easily form alloys with iron ("siderophiles").
