Less here than meets the eye....
People are constantly discovering new minerals. So what?
*Everything* on the surface of the Moon has a tiny bit of 3He in it. So what?
3He is a terrible fusion fuel; it's difficult to fuse. Sure, fusing doesn't make your reactor parts radioactive like Tritium does, but if you can't get it to fuse then so what?
Don't get me wrong: it's neat that they brought samples back from the Moon. But this is a tempest in a teapot, a transparent effort to get a headline.
Yawn.
