I recently updated the TMR Advanced Rare-Earth Projects Index, to reflect project updates since the last edition. The effective date of the latest edition is August 2, 2015. The specifics:
- On May 11, 2015, Ucore Rare Metals Inc. (TSX.V:UCU) announced an updated NI 43-101-guided mineral-resource estimate for the Bokan-Dotson Ridge project in the USA. According to the associated news release, 4.8 Mt of the resource is at the Indicated level @ 0.602% TREO and 1.1 Mt is at the Inferred level @ 0.603% TREO, both at a cut-off grade of 0.40% TREO;
- On May 12, 2015, Frontier Rare Earths Ltd. (TSX:FRO) announced an updated NI 43-101-guided mineral-resource estimate for the Zandkopsdrift project in South Africa as part of a completed pre-feasibility study. According to the associated news release, 23.0 Mt of the resource is at the Measured level @ 2.07% TREO, 22.7 Mt is at the Indicated level @ 1.73% TREO, and 1.1 Mt is at the Inferred level @ 1.52% TREO, each at a cut-off grade of 1% TREO; and
- On June 17, 2015, Geomega Resources Inc. (TSX.V:GMA) announced an updated NI 43-101-guided mineral-resource estimate for the Montviel project in Canada. According to the associated news release, 82.4 Mt of the resource is at the Indicated level @ 1.51% TREO and 184.2 Mt is at the Inferred level @ 1.43% TREO, at an unspecified cut-off grade.
The Index currently consists of 58 rare-earth mineral resources, associated with 53 advanced rare-earth projects and 49 companies, located in 35 regions within 16 countries.
I have also updated the pricing used in the Index data, to reflect the average monthly prices for July 2015.

Thanks for your good informs.
I found out the TREO are below 2.0wt%.
Do they have a value to refine for industrial use?
And normally how is min. wt% for economical refinery?
As I know the limitation is more than 2.0%( volume % ) grade.
Also how calculate from volume% to wt% of grade?
Our company have a rare earth mine of 0.6-1.3% grade in Korea.
Now we are only producting/saleing for fertilizer and animal feed.
I want to know this grade has value for development of industrial refinery or not.
Too many questions? sorry.
Thank you Gareth for your valuale data.
