RE:MALI Government Don't know about valuations. To what extent these gold producers are affected by the Mali news, I just checked their increase/decrease. Angl os down .17%, ABX is down .91% while BTO is down 2.67%. These numbers were as of 1.20 PM EDT. The decrease in each case is probably affected by the extent that their respective gold production is from Mali. That's probably why BTO is down the most.
I wouldn't worry about it. It's always a concern, but if the military horn in on the gold producers, they're simply killing the goose that lays their golden eggs. Many investors had concerns in the previous military coup too.
