Not all mining will be at those depths. At least one player is looking elsewhere.
Neptune Minerals is focusing its efforts at SMS sites at the more prospective convergent plate margin sites which are dominant in the “West Pacific Ring of Fire” in water depths between approximately 500 and 2500 meters.
Granted their target may not be nodules per se but the sulfide rich deposits.
I’m not against the concept and I would love to see some stacked units converted. Been watching this Neptune thing for a long time and their info seems to have changed from active mining to a role further “upstream” now mentioning the sale of their tenements as a revenue approach.
But my point was in development of these resources we as a species might want to consider the unintended consequences. Perhaps merely saying “what could go wrong” during ramp up may not be the best risk assessment strategy. Serious people Have been studying this for years and the Internet has loads of info about methods, legal aspects and environmental aspects. I don’t think we are likely to get the last word on this from a gCaptain thread where standard procedure for some seems to be trot out the evil environmentalist labels at the drop of a hat. There’s tons of info available.
