Ann: Rare Earth Elements - Mt Stirling Project Update, page-7

I like this part of the announcement:

In this regard, Helman and Duncan (2014)*(1) are of the view that the value of a deposit will
be governed by both the distribution of the individual REEs and their host minerals.
For example, they consider that it is likely that leachable deposits, like Yttria, although of
lower grade but with a high ratio of HREYO/TREYO and low radioactivity, could be more
economic than higher grade primary deposits containing REE-bearing minerals that require
aggressive leaching conditions and high capital costs.
