The title is far too generous. They've only launched a single spacecraft so far which failed due to communications issues. They're planning to launch a second spacecraft in Q4 this year which will fly by an asteroid and take pictures. They're planning a third spacecraft which they say will dock to an asteroid using magnets because it's "likely iron rich" and basically take measurements.

Nothing about actually mining resources and returning those materials to Earth. So they've gotten funding from investors? In the past, even dumber endeavours have gotten even more funding than this, it really doesn't mean anything.
