no way ardea is 1/5th or so, page-2

I agree with most of what you wrote. Cleanteq recently updated its cobalt source, and now grades at .13. Its .13 deposit is approx twice as large as Ardea's .13, but I agree Ardea will grow with future updates as well. Its large low grade zone is an attractive asset due to its size. However most people don't understand that Cleanteq is more of a tech company, so its not exactly apples to apples. It is probable that cleanteq will make more money with its proprietary suite of technologies then by selling sulphates and oxides. How much of that is built into their present stock price is hard to tell. In any case, I think both companies are fantastic investments, and all the Australian cobalt companies will have no problem selling out at probably higher prices.
