This is an interesting interview with the CEO of Barrick explaining his strategy. He is making the case that risks in Russia can be controlled if you deal right with Putin, whereas Latin America is getting difficult with environmental opposition.
What he says that is not so helpful is that "It is not my focus to make money on the stock of these companies. The juice is in the back-in rights." So Barrick are not taking any responsibility for where the Celtic share price goes.
Still the strategy seems sound and shows why it will be useful in the long run to have a major as partner in Russia.
