The last time that i saw something like this was when Howard Hughes builded USNS Glomar Explorer with the porpouse to extract Manganese modules from the sea floor .This cover story became very influential, spurring many others to examine the idea. But it was a secret plan to recover K-129 , a soviet submarine lost in April 1968.

In regards to the reason for this endeavor, several studies have shown many of the important metals for high technology such as platinum at present global growth rates, especially in the emerging economies such as China, will be depleted within decades:

Also your study ignores the development of platinum recycling - a lot of the platinum is actually in old cars and can be recycled, though with a hefty price. |

Not to mention the fact that getting your hardware to the work site is a whole lot more expensive. Sinking stuff is so cheap that people do it even when they don't want to. |

Deep sea drilling had the advantage it developed incrementaly, people didn't immediatly go from land drillling to deap sea drilling requiring fully robotic operations. They started in shallow waters easily accesible to human divers and then gradually built up technology and experiance to access gas and oil reserves located in deep ocean. In case of asteorid mining even first steps are multi billion endeavours and probability of multi billion failure very high because nothing like that has ever done before. |

Also, you should not regard "Business as Usual" as a good base for extrapolations... markets adapt pretty fast, especially in time frames beyond one decade. And asteroid mining is just the most expensive form of getting such minerals. |

In any case, here are some peer-reviewed papers that discuss this issue: Metal stocks and sustainability. R. B. Gordon*, M. Bertram†,‡, and T. E. Graedel†,§ PNAS January 31, 2006 vol. 103 no. 5 1209-1214. Quote:

And of course also if such scarcity estimates are valid, then this clearly would have a major impact on the question of the profitability of the space mining ventures. ![]() Bob Clark |

I might sound petty of me to note this, but after going through the (sparse) info Planetary Resources provides, it would appear that James Cameron is but a high profile mouthpiece for the group, not the guy "launching" the business. He's not even listed as an investor, but as an "adviser."
I wonder if they are paying him, or if he's just in it for the publicity? |

I think more the second. Also, I think this '' asteroid mining company'' never reach a meter in space.
