geigercounters are very sophisticated, page-6

re: rtm's methods however if you look at the pre-open, it seems that the investors have clued up the fact;

- any modern Geiger counters can diffrentiate between
thorium and Uranium
- RTM wouldn't be able to post "Uranium discovery" on the 18th of March if in the slightest chance the radiometric anomalies was anything else, Until they got the assay results!!!

Eitherway though, there is fantastic $$$$ being made trading RTM and only fools like sb2000 and saxien would be missing out!
