im not a holder, but from a very breif look at the ann it seems that all they have done is used a different method to analyse the rocks.
Seems a bit dodgy to me. IE - why did they need to use this method in the first place? what was wrong with the original way?
just seems as though they are trying to push the price. but i have very limited geo knowledge so dont take any notice of what i say.
Dear Prawn,
Typically you use a very aggressive solution to dissolve your target metal and then assay the solution. Unfortunately much of the tin and tungsten failed to dissolve into solution thus giving a low reading. XRF is a more precise way of assaying for tungsten. Hazelwood Resources are using this technique in their tunsten assaying as well. The lab advised RAU to re-assay and the results increased by about 1000% for both tin and tungsten. IMHO RAU may be sitting on a very large and very rich tungsten target /deposit at Whumbal West. Good luck to all longs.
