Norwegian undersea metals find:
There are three types of mineral deposits on the seabed; manganese nodules, manganese crusts and sulphides. All three types contain multiple metals, and they are located at significant sea depths, mainly between 1500 and 6000 metres. On the Norwegian shelf, manganese crusts and sulphides have been found at depths around 3000 metres.
Yes, OK, all known, but they’ve gained more detail:
“The volume of recoverable resources depends on technology and economy. It remains to be seen whether the areas will be opened, and whether production can be profitable from a financial standpoint”.
Also true, these are resources, not reserves. Actually, they’re not even resources in the technical jargon, they’re just stuff that is there. We’ve no even general indication that these will be mineable economically.
15,000 tonnes of hafnium
Umm, not really. There might be 750k tonnes – or so – of Zr, which then contains Hf, but Hf separately, no.
56,000 tonnes of scandium
Well, maybe. But only because they’re talking about all the rock in some vast area of the Norwegian arctic.
This is the sort of thing to put down as vaguely interesting. There are only 92 elements (before we get to manmade ones) so everything is made of them. An, everything is made of them in varying proportion. So if you add up some vast amount of rock – “deepwater areas in the Norwegian Sea and the Greenland Sea” and so the seabed of 2.5 million km, or much more than 10x the land area of England – then you’re going to find lots of metals. Because metals is what stuff is made of, see?
In terms of mineral availability this is about as exciting as finding out that Cornwall is made of rock.
