Gayton is no longer a director according to SVM's website, where his pic and bio have been removed. I suspect his departure relates to the Barron's article. SVM is just in too much trouble now for someone as wealthy as Gayton to be involved. Don't forget that Rui Feng moved to Singapore. The gang is clearing out of Canada, fast.
I'm not sure if Lorne "went on his sabbatical" -- or just wanted to get out of his legal liability as an officer of Silvercorp (Corporate Secretary) back then... but that was in early November, 2012... at the time SVM was trading around $6.
Okay, 50% decline in a year is not "the end of the world" as you say -- but it would have saved you a bit to pay more attention to the obvious warning signs. Just like now that Lorne is back from "sabbatical" his title is only SVP -- he's no longer an Officer or Director anymore -- and yet he's now in charge of the corporate headquarters and "general corporate matters"... that's a lot of responsibility for a lowly SVP. (Wonder how much he is being paid to fill all those shoes?!?)
