That Cohen article is published in the Financial Post today, so while the recommendation may be dated, it may have a current positive effect.
Here is a key quote: "There seems to be more worry embedded in the share price that what reality will be but we think it will wash out quite nicely. We feel that the valuation is probably trading at one-third the valuation of where it ought to be. Probably a $24 to $25 target would be reasonable."
The idea that the worry is greater than the reality is also implied in Marla's comments to laross19. The government is being overly demonstrative in showing the people that they will no longer be pushed around by foreign mining companies who have no regard for the country or the ecology. Posturing is what it is.
