Hi @stuwall

This article really explains how hard it is to try to invent a perm magnet without rare earths.

I love this quote:
"As the Japanese scientist Masato Sagawa – the inventor of neodymium magnets – pointed out in the opening plenary at REPM, it has taken 40 years of heroic effort for these materials to reach their current BHmax, which is about 90% of its theoretical maximum value, and to achieve high coercivity and high performance."

So even with modern technology speeding up the development...it would take minimum 10-20 years to get a prototype of a similar performance to NdPr Per magnets...and then they have to work out how to mass produce it.....at which point Nolans is about 2/3rds through its mine life....i'm happy to take that risk! ;-)
