They never gave anyone a time frame, we as investors just 'assumed' it'd be 30 days after the split. What the company has stated is that "it's VERY close"...
We've waited awhile for this time, so what's a little bit longer I suppose. Also, company continues to buy back shares.
One of my guesses is they were waiting on this drop in silver spot that we're now experiencing. I think the AMEX uplisting could go thru after USS maintains >$2 for a few days in this PM price drop.
