Rare Element Resources Files NI 43-101 Technical Report Detailing Previously Announced 65 Percent Increase in Total M&I Rare-Earth Mineral Resources

08:30 EDT Friday, May 03, 2013

LAKEWOOD, COLORADO--(Marketwired - May 3, 2013) - Rare Element Resources Ltd. (NYSE Amex:REE)(NYSE MKT:REE)(TSX:RES) (the "Company") announced today that it has filed a NI 43-101 Technical Report on the Mineral Reserves and Resources and Development of the Bull Hill Mine (the "Technical Report") for the Bear Lodge Rare Earth Project, located near Sundance, Wyoming. The Technical Report updates the resource for the Project and confirms the details provided in the Company's press release dated 18 March 2013 entitled "Rare Element Reports 65 Percent Increase of Total M&I Rare-Earth Mineral Resource at Bear Lodge." It incorporates more than 57,000 ft. (17,300 m) of exploration and development drilling conducted by the Company in 2012. The full Technical Report, prepared by Mr. Alan C. Noble, P.E., principal engineer of Ore Reserves Engineering (ORE) and a Qualified Person for the purpose of Canadian National Instrument 43‐101, Standards of Disclosure for Mineral Projects ("NI 43-101"), is available under the Company's SEDAR profile at www.sedar.com or on the Company's website at www.rareeleementresources.com. The Technical Report supersedes the previous technical report filed by the Company in April 2012.

Key highlights from the Company's drilling program to date include the following:

  • Increase in the total Measured and Indicated (M&I) oxide resource at Bear Lodge from 7.5 million tons (6.8 million tonnes) to 14.7 million tons (13.3 million tonnes) at an average grade of 3.22% rare earth oxide (REO), based on a 1.5% cutoff grade. This represents an increase in total pounds of REO resource of 65%, from 571 million to 944 million pounds.

  • Upgrade of the M&I resource at the Bull Hill deposit and establishment of the first-ever Indicated resource at the Whitetail Ridge deposit, located just northwest of the Bull Hill deposit.

  • Identification of high-grade zones that constitute an M&I resource of 6 million tons (5.4 million tonnes) grading 4.72% REO at a cutoff grade of 3% within the overall Bear Lodge resource.

"We are very pleased with the success of our 2012 drill program in expanding the Bear Lodge resource while maintaining a strong average grade of over 3.2% REO. Our project district has an excellent distribution and high abundance of Critical Rare Earth Elements, the higher-valued elements that we expect to experience better demand growth and price support over the longer term. Both the quantity and quality of our updated resource makes us confident in our assertion that the Bear Lodge Project is now a world-class, critical rare earth district," stated Randall J. Scott, President and Chief Executive Officer. "The increase in high-grade mineralization also gives us flexibility on our mine size and production rate, and may allow us to pursue an initial higher-grade, lower production scenario with lower capital cost if desired. This gives us flexibility and makes us better able to adjust to changing market conditions," he added.

The exploration and development drilling program undertaken by the Company in 2012 included 68 core holes, for a total of 57,419 ft. (17,506 m), and 42 reverse circulation drill holes, for a total of 24,805 ft. (7,562.5 m). The reverse circulation drill holes were used for exploration purposes and are not included in the resource estimation. In addition, 14 large diameter (PQ- and HQ-sized) holes totaling 6,853 ft. (2,089 m) provided bulk sample material for metallurgical testing. The Technical Report includes the results from all core drilling undertaken by the Company between 2009 and 2012.

The Company's resource in the Inferred category for all mineralization types increased to 42.3 million tons (38.4 million tonnes) with an average grade of 2.59% REO, from 34.6 million tons (31.4 million tonnes) at an average grade of 2.83% REO in 2012. Of the updated Inferred resource, 31.4 million tons is contained in near-surface Oxide and Oxide-Carbonate material.

The qualified mineral reserves identified in the previous Technical Report dated April 2012 have been carried forward. A new reserve has not been calculated under the Technical Report. These reserve estimates will be updated as part of the upcoming Feasibility Study, expected to begin in mid-2013.

For more details on the M&I and Inferred resources, as well as the rare earth element distribution and impact of cutoff grades on these deposits, please see the press release issued by the Company on 18 March 2013 or view the complete Technical Report, both of which can be found at www.rareelementresources.com. All resources reported herein comply with NI 43-101.

Rare Element defines Critical Rare Earth Elements as Neodymium (Nd), Praseodymium (Pr), Europium (Eu), Terbium (Tb), Dysprosium (Dy) and Yttrium (Y), based on their projected future demand and generally higher per kilogram price.

Qualified Persons

The new resource model and the NI 43-101 Technical Report on the Bear Lodge Property was prepared by Mr. Alan C. Noble, P.E., principal engineer of Ore Reserves Engineering (ORE), Jaye T. Pickarts, Chief Operating Officer of Rare Element, and Richard Larsen, Engineering Manager of Rare Element. Mr. Noble, P.E. is the Qualified Person for the purpose of Canadian National Instrument 43‐101, Standards of Disclosure for Mineral Projects ("NI 43-101") for this technical report. Mr. Noble performed the mineral resource estimation and is the primary author of the technical report. Jaye T. Pickarts, P.E. and Richard K. Larsen, P.E. assembled the geological, exploration, metallurgy, and engineering activity information for this report, and they are both Qualified Persons. Mr. Pickarts was engaged in the preparation of metallurgical test programs and baseline environmental studies on the Bear Lodge Project. In 2011, he became the Company's Chief Operating Officer, and he thereafter managed and supervised all of the metallurgical and engineering programs for the project. Richard Larsen worked on the property as a geologist for Duval Corporation from 1975-1978. Mr. Larsen was hired by the Company in December 2011 as Senior Development Geologist, then Engineering Manager. He was responsible for managing and supervising the Company's development drilling at the Bull Hill REE deposit in 2012.

Mineral Resources are not Reserves

Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for minability, selectivity, mining loss, and dilution. These mineral resource estimates are in the measured, indicated, and inferred mineral resource categories. Inferred mineral resources are normally considered too speculative geologically for the application of economic considerations that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated mineral resource categories through further drilling, or into mineral reserves once economic considerations are applied.

Rare Element announced positive economic results from its pre-feasibility study (PFS) on 1 March 2012 and a revised news release on 12 April 2012. The PFS established a proven plus probable mineral reserve for the Bull Hill deposit that contains 7.914 million tons (7.2M metric tonnes) at a grade of 3.12% REO and at a cutoff grade of 1.1% REO.

Rare Element Resources Ltd. is a publicly traded mineral resource company focused on exploration and development of rare-earth elements (REEs), with a significant distribution of critical rare earths (CREEs). In addition to the REE exploration and evaluation efforts, the Company controls the Sundance gold project, which is located on the same property in Wyoming.
