Gold is running just below $1,200/oz.
Cost of mining gold from that asteroid would be 2 to 3 times that, at a minimum.
Same would be true of all metals.
Fake News.

You wouldn’t USE anything except maybe a few wildly exotic isotopes found there, on earth. You would use that rock as a ready made mine/factory for building stuff out there.
