Agreed, and moreso why don't they have information on Hafnium? Is it a secret? Does nobody have an estimate of how much there is scattered about? Are mining companies busy digging for diamonds or copper and oops a lump of hafnium pops up ('ooh what luck, I know a power station owner who will want that!')?
I do hope there's some big Hafnium mining monopoly conspiracy behind this! ;)
I'm the type of guy who goes and googles this kind of thing..... It looks like halfnium is a byproduct of zirconium production (1:50 ratio is what the pdf says), and that we have a decent chunk of reserve (worldwide), compared with the rate it's mined.
