RE:re re how big is itWell I don't know if $.05 shares of the neighbours are really having that much of an effect on investing in Zen; in fact, all the hubbub they're causing is probably bringing even more attention to it.
Of course, your opinion is yours, and as such can't be debated, but your conclusions leading you to that opinion might be suspect. The mining costs will not be high, and they may be extraordinarily low, as has been outlined by smarter people than me.
Anyway, this is CCB's board, and Zen is mentioned too often here. I will quibble with you about your prognostications regarding CCB. They have the right kind of graphite, near surface and in a great location. However, they must be able to get their graphite out of the ground in bulk, which may prove difficult. They also need to economically purify their graphite from the current 60-80% to the more valuable 95-99+%. Sri Lanka's graphite has, I believe, sulphur impurities in it, which intercolate themselves in between the graphite layers and resist removal. If CCB has similar problems, they will not be able to command top dollar, which may be important if they also have issues with getting the graphite out.
I wish you all the best with CCB (and therefore wish it for myself, too), but I wish the CCB board would let the Zen bashing rest.
