In this article from last year if you are looking to buy a rare earths mine then dyprosium and terbium are a must for success

It is an interview with Jack Lifton and he makes alot of valid points

Mt weld central deposit including the Duncan deposit only has Dysprosium at .124% and terbium at .068%


Rare Earth Oxide Mt Weld Distribution
21/03/11

Lanthanum Oxide 25.50%
Cerium Oxide 46.74%
Neodymium Oxide 18.50%
Praseodymium Oxide 5.32%
Samarium Oxide 2.27%
Dysprosium Oxide 0.124%
Europium Oxide 0.443%
Terbium Oxide 0.068%


Note: Mt Weld distribution totals 98.9%, the balance is made up of Gadolinium, Holmium, Erbium and Yttrium oxides.




TABLE 4: COMPARISON OF 2010 RESOURCE ESTIMATE AND 2008 RESOURCE ESTIMATE

2008 Model

According to this Mt weld has a total resource of 1,416,000 t at .124% Dysprosium which = 1756 t in total and

terbium of 1,416000 t x .068% which = 963 t


The Crown deposit has resource of 437,000t and Dysprosium at 1.76% for 7700 t
and terbium at .33% for 963 t

That means there is 50% more terbium in the Crown deposit and over 4 times more of dysprosium in the Crown deposit than at Mt Weld


Also Mt Weld has little Yttrium at 1680 ppm (.168%) for a total of 2,379 t while Crown deposit has Yttrium at
5.76% for a total of 25,200 t

That is more than a 10 fold increase in Yttrium at Crown compared to Mt Weld


The directors of Lynas must be called to answer

Why are they selling most of our HEAVY Rare Earths?
