Yep, large volumes for UNS. That's usual though when the stock has a story. I'd like to see some broker data. Its also not uncommon to see day traders take advantage in stituations like this which could aacount for some of the vol. There's been a nice 1/2-1cent scalp over the last few days. As mentioned before it could also be a strategy to get a partner in on the cheap. IMO
