it was suggested that it has something to do with the rain. ASL was forced to use power generators at their mine in Ghana because of power allocation off the main power grid. While this method was more costly, production wasn't suppose to be lower.
Unconfirmed, but if the trend continues, maybe someone wants to buy them out. As a tipoff, look for heavy volume accompanied by a further price increase in ASL with falling gold prices. ABX would be a likely suitor.
May be ASL home base - Ghana - now looks prety good, when NEM got into trouble in Pacific Rim? Now investors reavaluating ASL based on reserves, production and cost/oz to the level of ABX and NEM. It should be $13-14, I belive, if NEM and ABX at the current level.
