RE: VALUE ISSUEI assume this post comes with an irony alert!
In any event, according to some frequent posters here, the decline in AUM market value is caused by a plot among insiders to impoverish themselves. This seems less than likely to me, but I don't have the benefit of being a long-time shareholder of ECU, which apparently attracted a motley crew of wishful dreamers and magical thinkers.
Judging from their career achievements of the founding AUM group, we have every reason to believe that management can upgrade Mexican operations successfully and complete the mining plan for El Quevar.
Returning to the theme - yes, this price drop is typical of the sector.
