"...draw attention of new potential investors, who will be drawn to it by "cobalt" but who will then learn the rest of the story."

Yes, but cobalt is "the flavor of the month" in the exploration/promotion business, now that the bloom is off lithium.  It will be hard to get today's PR from LBSR out in front of all those other companies pushing a cobalt connection.

Like I said, I'd like to be wrong.
