If you are buying tomorrow for a potential short gainer, I would buy NWOG. I think AURC will probably pull back after today's gains unless they follow up quickly with more PR's.
If you are looking to keep your money there for a bit of time, then I'd go with AURC, but wait for it to fall below .12 before buying. With the tighter share structure and, at this time, clearer game plan, AURC should get you a better return through the spring.
That's what I think, but I'm having a dismal autumn stock-wise, so I wouldn't take my advice if I was you...
