2. The place of the Rare Earths at “value as mined
and concentrated”
Mechanically Concentrated rare earth ores are the lowest value point in
the supply chain

3. At the mine, as defined on the previous page, the toal value of the rare
earths was estimated to be just 15/100 of 1 % of the total value of all
global metal production in 2010.
