refinery for the project outside of Greenland. The company had originally considered establishing the refinery for U and HREEs and LREEs in southern Greenland, in proximity to the mine and concen- trator. Search Minerals Inc. announced a revised pre- liminary economic assessment (PEA) for its Foxtrot REE project, which is located in Labrador, Canada. Highlights include a reduction in capital costs from $469 million to $221 million, with a 3.8-year payback period. Further, net revenue for the project has in- creased by $110 per metric tonne milled and oper- ating expenditures have increased by $38 per metric tonne. The revised project will now focus on higher grade REE material of ‘‘0.89% total REE ... on average, which compares to the 0.58% TREE on average for the original bulk open pit concept,’’ according to a press release. Peak Resources Ltd. announced further improvements to beneficiation process for its Ngualla REE project in Tanzania. It confirmed that the ability to concentrate mineralization at an early stage prior to acid leach recovery is likely to have a ‘‘significant impact’’ on costs. One improvement is that the opti- mization of the beneficiation process reduces by 43% the mass of feed to be treated by the acid leach recovery process. The latest test work also indicated that conventional magnetic separation and flotation techniques will reduce the mass of the feed minerali- zation by 78% through the rejection of relatively mineralized barite and iron oxides. The cost reduc- tions will be quantified in a revision of the scoping study, and an economic assessment is scheduled for completion in the second quarter of 2013. Lynas Corporation, the major Australian REE miner, plans to implement a price schedule for its REE concentrates on July 1, 2013. The company said recent spot prices for REEs of $16 to $20 per kilogram are 25% below the price that producers need for sustainable operations. Prices had been $100 per kilogram less than 3 years ago. Rare Element Resources Ltd. announced a 65% increase to its total measured and indicated REE resource estimate for the Bear Lodge project. The increase saw a rise from 571 to 944 million pounds (259 to 428 million kg) of rare earth oxides (REO). The updated NI 43-101 compliant resource estimate includes the first indicated resource at the HREE-enriched Whitetail Ridge deposit and high grades of critical REOs (CREOs) in all deposits. CREOs are REOs that have the highest values and the strongest projected future growth. Great Western Minerals Group Ltd. released a PEA for its Steenkampskraal REE project that indicates strong potential for its integrated business model. Project highlights include a $555-million after-tax net present value when applying a 10% discount rate, a 28% South African corporate tax rate, and a 66% after-tax internal rate of return. On an after-tax basis, the project has a 4.3-year esti- mated payback period from the start of underground mining production. It also has an 11-year potential mine life. Tasman Metals Ltd. announced the first NI 43- 101 compliant independent resource estimate for its 100%-owned Olserum HREE project in Sweden. Its press release notes that highlights include a 0.4% total REO (TREO) cut-off, an indicated resource of 4.5 million metric tonnes (4.9 short tons) at 0.60% TREO and an inferred resource of 3.3 million metric tonnes (3.6 million short tons) at 0.63% TREO. It adds that ‘‘higher value’’ HREEs comprise 34% of the total REE content at Olserum, with the five critical REEs (Dy, Tb, Eu, Nd, and Y) comprising approximately 40% of the REE content. Ucore Rare Metals Inc. confirmed that U.S. senators Lisa Murkowski and Mark Begich jointly introduced a bill in Washington, D.C. to authorize construction of a road to the Niblack and Bokan Mountain projects on Prince of Wales Island. Ucore also highlighted the introduction of Senate Joint Resolution No. 8 in the Legislature of the State of Alaska by senators Lesil McGuire, Berta Gardner, and Johnny Ellis. The resolution supports the con- tinued and increased exploration, extraction, pro- cessing, and production of REEs in the state. It is positive news for the project as it supports a number of initiatives and urges state agencies that administer the permits required for the development of REE projects in Alaska to expedite the consideration and issuance of permits for the development of REE deposits. Quest Rare Minerals Ltd. provided an update on the preparation of a Preliminary Feasibility Study (PFS) for the B-Zone deposit at its Strange Lake HREE deposit, located in Quebec. It confirmed that significant development work demonstrates that Strange Lake is a ‘‘very large rare earth project’’ with high concentrations of HREEs, as well as by- products such as Zr and Nb.

On other developments, the USGS has built a website offering information on mineral deposits containing REE American Association of Petroleum Geologists, Energy Minerals Division
