Japan becomes the first nation to mine a deep-sea hydrothermal vent

Posted on September 27, 2017 By Andrew Thaler 1 Comment on Japan becomes the first nation to mine a deep-sea hydrothermal vent

Sixteen hundred meters deep, off the coast of Okinawa, a new kind of mining just cut it’s teeth.

Earlier today, the Japan Times reported that a mining tool has successfully extracted zinc and other metals from a hydrothermal vent on the seafloor. There’s not much to go on yet. We don’t know if these were active or dormant vents (though dormant doesn’t mean biologically dead). We don’t know the specific location of the experimental mine site. And we don’t know the footprint of the ore prospect. But we do know that Japan has identified at least 6 potential mining sites within its exclusive economic zone and that plans are moving forward for a commercial mining venture in mid-2020. I’ve only found one report in English and from the look of things, there’s only a press release circulating right now, but I’m certain we’ll be hearing much more about this in the coming weeks.

We’re still watching to see what Nautilus Minerals does at Solwara 1 and how manganese nodule mining proposals in the Clarion Clipperton fracture zone are progressing but Japan’s mining efforts present a sea change in how to anticipate future deep-sea mining efforts. Private commercial ventures are dependent on the whims of the global commodities market and subject to national and international regulation. National efforts are driven by the need for resource independence. I was aware of Japan’s efforts, but didn’t realize that they were as close as they are to being ready for production.

For the last 10 years, we’ve been saying that deep-sea mining of hydrothermal vents is imminent. Well, it’s here.

    We’ve chatted about this before. If 100 square acres is mined, is that the beginning of the end? Or is it acceptable?
