OG, I can't vouch for your costs, but they seem to be consistent with the numbers I've seen touted on a couple of forums in the last 12 months. By the way, the company has a scoping study underway to assess business models for production between 5 and 10 million tonnes per annum - which no doubt makes the potential share price even better than what you've calculated. Re the current share price - eventually the current selling will be absorbed by those who are looking for long term gains and consequently the price will go up - but not sure how long before this occurs. It did move from 70cents to $1.60 excessively fast, so the correction is no surprise.
