Kinross comes close and Rubicon had a similar plunge to ~3 bucks but has recovered to 3.66 from going from over 6.40 less than a year ago. Then there's LSG that has gone from over 4.40 to 1.30 to 1.59 today not to mention the biggest see saw swing of them all - Jag which went from over 14$ to $4 back to $8. So I guess San Gold is no different. There goes that theory. I'm sure there's more but those were the only 5 I looked at and they all have experienced mercurial swings.
