Medium to long term prospects look excellent for reasons listed by you Focker.
However, over the next week or so, there will be 20m shares allotted through option conversion, some of which were purchased in the low 30s. Therefore, I expect some volatility in the sp until that gets bedded down. Might provide another entry point in mid 30s for anyone still wanting to get set.
The only thing to offset that is more good news in the short term. In any case, I like the fact they have plenty of cash, substantial backers, top management and superb prospects in iron ore, tin, coal, etc.
