For whoever might be interested in REE info... Gareth Hatch of http://www.techmetalsresearch.com/ just sent out an email, saying "The US Department of Energy (DOE) has released an update to its Critical Materials Strategy, which was first published as a report in December 2011... New sections include one that covers the use of rare earths in fluid cracking catalysts, and how the petrochemical refining industry reacted to escalating prices of materials in 2011." http://energy.gov/sites/prod/files/DOE_CMS_2011.pdf FYI, these guys closely track ASX REE companies, so their research is relevant to aussies.
