I remember listening to Franklin of the GSC talk about the Straits of Jaun de Fuca "orebody" which was contemporaneously forming from a vent on the sea floor. It was running about 5 to 10% copper. I inquired of him whether or not the body might be economic. His reply was at 5000 metres deep, these things were "not economic, no @#%@# way." My demurral did not carry much weight, but it was observed that the deposits are not that strongly consolidated and very exposed. The only cost to extract them is to suck hard enough to break them up, or scrabble and suck hard and carry that stream to surface. I thot it could be done, as the ship and all would only cost about 5 to 7 million and the mining and extracting equipment about the same. It should be feasible to draw off about 2000 tpd of the material and return the waste to the seafloor. At 5% copper that is 600K bucks per day. I think there is some profit that could be made. Technical difficulties in extraction of ore are not insurmountable. Where the deposit gets more consolidated, it presents a bit of a problem. You need some kind of crawler carbide cutter head thingie.

Thanks MS smartest person. I will look that one over this weekend. That is a romantic notion mining the New guinea seabed.

Cheers
