The stock took a big hit in recent months as investors from the previous private placement sold and the company had to lower the price for its new placement to complete the feasibility study down to .80. Now that the second placement is closing, the selling pressure is abating and the stock is starting to rebound, joining other zinc stocks which have been rallying on the new 16-year high price of zinc: http://www.kitcometals.com/charts/ZINC_historical.html
The price of zinc has doubled in the past year and a half and looks headed much higher given the supply/demand situation. MMGG trading at less than 1/3 what it was when zinc was half the current price (and before the feasibility study had started and the metallurgy was proven) is a steal, particularly if they can get listed (most likely in Canada). MMGG should at least return to above the $3 it traded at in 2004 once the feasibility study is completed.
