Fascinating stuff. Of course if that asteroid landed, or was found and could be mined, the value would very quickly go from the spot price of the metal, to whatever minimum price the seller was willing to accept. US$3.5 trillion or whatever the number is, could go to US$250M or less, good lesson in supply and demand why industrial commodities, without a open and transparent market like the LME (cough) can often be subject to less or more volatility. Anyone point me to comparison of volatility between metals traded on the LME/COMEX etc and industrial metals/minerals where there is no public exchange? Would be interesting to see if large and highly speculated (leveraged) markets such as gold are inherently more volatile than say an industrial commodity (rutile, potash, lithium etc).

Other than Antarctica, where are the potential huge platinum discoveries to be made in the future? (yes they will mine it one day there, perhaps not in our lifetimes).
