It would help, but I wonder why they didn't start out on one of the major exchanges in the first place. If it were not for their close association with First Majestic Silver I'd be more critical of the stock being OTC, but the relationship and shared leadership makes me willing to accept penny stock status for now.
I would think at some point they want to move to a better/more visible exchange. They need to build to that change I would think, but in time I think we'll see it happen.
The institutional following for First Mining is probably right now 99% higher than most of the Companies traded on the OTC.
