From this latest news release (January 18th 2013)  Northern Graphite NGC $1.16  -.09  -7.20% looks to be moving ahead with plans for their graphite mine.  The graphite they found in eastern Ontario is large "flake" graphite which has more inpurities in it compared to the northern Ontario Zenyatta "vein" graphite deposit being the largest and highest purity vein deposit  found so far in the world. The market is still figuring the stock price valuation of the ZEN stock. ZEN $1.95  -.10  -4.88%

It is a good measure of what it takes to get a mine up and running which Northern Graphite is setting in motion their plans for a producing mine.
