As always, the key to underwater mining is environmental impact.

We are only starting to come to terms with the devastation caused by the "fish miners" who drag huge nets along the ocean floor. The shallower the water, the more likely it is to be important marine habitat.

This is not a comment on Nautilus in particular, as I haven't look at the company or their plans at all.

It isn't that shallow. For envi reasons you don't want shallow. You don't want to disturb coral, or spawning beds. Black smokers are out of that territory. I believe they are at 2000 metres or more

Not to far from New Guinea is the Mariana Trench @ 11,280 metres deep. I am pretty sure they are not in ditch.

The Pacific ocean is about 12,750 feet deep on average. The great advantage the British Navy had over other navies in the 17th and 18th centuries was that they could anchor just about anywhere they wanted at sea in the Pacific. This meant that they needed about 31,875 feet of anchor chain of perhaps 8 inch links or perhaps 180 tons of ballast weight. Once the chain was out, the boat floated rather like a cork and was more seaworthy to a degree.
