With respect 225, comparing ZEN to NOT is like apples & oranges.
1. ZEN is located in civilization....close to major roads, rail, power and near built up towns.
2. NOT may have relatively high grade nickel and perhaps some mineable chromite but their cost of production when you include capital cost will be very high....if the gov't ever chips in to get the project going....
3. One has to get their head around the meaning of "high purity" graphite. Most graphite could be refined to "high purity" but the question is at what cost? ZEN is proving that they can produce a powder product that can be used for lithium-ion batteries at a low enough cost that they can compete with synthetic graphite and actually capture the market because they can sell their product at a lower cost than current producers of synthetic graphite.
4, NOT (or someone) MAY someday produce nickel at RoF but it will not be any different than the nickel produced elsewhere including Sudbury.
5. Realistcally NOT will not be producing before 2020 while ZEN could be producing in 2-3 years.
IMHO ZEN is potentially a 10 bagger even from here.
