Well, if the plunge in IO price (halving) is because of a massive drop in Chinese IO demand because China's economy has suffered a massive hard landing or in a perpetual structural decline, then no IO projects (green, brown or any color is worth the risk).
However if the halving of the IO price (happening within the short space of just a few months on INCREASING chinese IO demand) where the one's responsible confess to it being a ploy to snuff out 32 future iron ore projects world-wide in order to further concentrate the monopolization, that's a different matter.
