Personally I don't care what anyone else says about your strategy of having 45% in cash sitting on the side awaiting news. I like it.
This way, once the big news pops, you have plenty on the side to slap the Hades out of the ask and keep others waiting until the last minute to buy in out of the initial low hanging fruit, and might I say furiously chasing as well.
According to my calculations, if you are still holding 10-15 million ("I Am Banro"), the ask slapping you can provide could run this to three or four dollars a share, making you quickly worth a cool $30-60 million...all without waiting for the price of gold to rise, or the third and fourth mines to begin commercial production.
Hopefully Gramercy is below the 20% threshold to maintain their vote now, and I think they are, otherwise they could throw a wrench in your plan. But I really like the idea of you chasing up the ask a lot. Give her all you've got! Kudos.
