ELI5: If we discover a really rare mineral/element on another planet that could be used for many purposes on Earth (like in Avatar), how will we share it?

Suppose it is useful in making superoconductors/supermagnets or efficient desalination of sea-water or unlimited energy...

Will the finders be keepers?


Do the countries already have a treaty to deal with it?

Do they just let multinational mining giants go get it?

Will there be a new way to share/allot this? Who will decide the rules?

Who knows?

Currently there are treaties which say that space belongs to all of humanity...... but that's between countries.  If private companies get up there then they are probably not bound by the treaties unless their country says that they are.
