US GOLD (UXG) proposed merger with MINERA ANDES (MNEAF)

"As proposed by Mr. McEwen, Minera Andes shareholders would receive 0.4 of a US Gold common share for each 1.0 Minera Andes share currently held. This ratio is within an average trading range established during the past six months and presents a slight premium over the previous day's closing price on June 13th, 2011. The total number of shares outstanding in the combined company would be approximately 252.7 million."

Hoping someone will chime in on this situation. This is the first time I've been in the situation of owning both of these miners. In these types of mergers, is it usually bullish? or a wash understanding UXG gets diluted? Do you think MNEAF will be a drag on UXG? Request bullish and bearish comments on these two miners.
