RE: EXmin or GaribaldiI certainly think exm has great potential at this price range. With the bigtime partners on some of the projects, I think it also gives the stock some solid security from downside risk as well. I don't know anything about Garibaldi. You might want to check out Coach's message board for lots of good Sierra Madre discussion and other gold juniors and up and comers.
You also might want to check out GCU. Of all my exploration stocks, I think this one has the most potential for as much as a 10 to 50 bagger over the next several years. They are into Gallium, REE's, Gold and Uranium. But the Gallium and a very good looking gold property in Canada are Gcu's main upside and focus at this point.
