NYSE MKT: REE & TSX: RES Bear Lodge Critical Rare Earth Project A Year of Dramatic Change Technology Metals Summit – March 2013 1 Disclaimer The information contained herein, while obtained from sources which we believe are reliable, is not guaranteed as to its accuracy or completeness. The company is an exploration company and its mineral project has yet to be proven to be economic. Some references to geologic and technical information contained herein are historical or have been generated by external consultants who may or may not be QPs under NI 43-101 and are therefore not in accordance with the requirements under NI 43-101 or have to be prepared in accordance with a preliminary or final feasibility study. The content of this presentation is for information purposes only and does not constitute an offer to sell or a solicitation to purchase any securities referred to herein. Forward-looking statements: This presentation includes certain forward-looking statements about future events and/or financial results which are forward-looking in nature and subject to risks and uncertainties. Forward-looking statements include without limitation, statements regarding the company’s plan, goals or objectives and future mineral projects, potential mineralization, resources and reserves, exploration results and future plans and objectives of Rare Element Resources. Forward-looking statements can generally be identified by the use of forward-looking terminology such as “may”, “will”, “expect”, “intend”, “estimate”, “anticipate”, “believe”, or “continue” or the negative thereof or variations thereon or similar terminology. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from expectations include risks associated with permitting, mining generally, and pre-development stage projects in particular. Potential investors should conduct their own investigations as to the suitability of investing in securities of Rare Element Resources. Cautionary Note to U.S. Investors Concerning Estimates of Measured, Indicated and Inferred Resources This presentation uses the term “Inferred” Mineral Resources. U.S. investors are advised that while such terms are recognized and required by Canadian regulations, the Securities and Exchange Commission does not recognize them. “Inferred Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Resources may not form the basis of feasibility or other economic studies. U.S. investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable. 2 2 CREO Comparative Value Critical Elements- Nd,Pr,Eu,Tb,Dy & Y 24 23 22 21 20 19 18 17 16 15 ProjectP Number 14 13 12 11 10 9 8 Rare Element Resources Bull Hill & Whitetail, 1.5% cut-off 6 Rare Element Resources Whitetail Deposit Rare Element Resources Bull Hill & Whitetail, 3.0% cut-off 3 2 1 $- $500 $1,000 $1,500 $2,000 $2,500 US$ per Metric Tonne 1) Rare Element Resources internal studies 2) January 2013 prices 3 3 CREO Comparative Value Critical REO + By-products 24 23 22 21 20 19 18 17 16 15 Project Number 14 13 12 11 Rare Element Resources Bull Hill & Whitetail, 1.5% cut-off 9 8 Rare Element Resources Whitetail Deposit 6 5 Rare Element Resources Bull Hill & Whitetail, 3.0% cut-off 3 2 1 Critical Elements- Nd,Pr,Eu,Tb,Dy & Y $- $500 $1,000 $1,500 $2,000 $2,500 $3,000 US$ per MetricTonne 1) Rare Element Resources internal studies 2) January 2013 prices 4 4 Distribution of Bull Hill + Whitetail Oxide Zone REEs Rare-Earth Element Lanthanum Cerium Neodymium Praseodymium Samarium Europium Gadolinium Wt-% Oxide Distribution(1) 27.3% 43.4% 17.9% 5.0% 2.9% 0.6% 1.4% Terbium 0.1% 3.5% Dysprosium 0.3% 5.2% Yttrium Total 1.0% 99.9% 0.8% 99.9% % Relative Value(2) 6.4% 11.3% 35.1% 10.3% 1.5% 24.2% 1.6% (1) Based on M&I Resources from News Release dated March 18, 2013 (2) Based on January 1, 2013 prices of REEs 5 5 M&I Resources Estimated REO Resources (in millions of kilograms) 450 428 400 65% Increase 350 Million kgs 300 259 250 200 150 100 50 Indicated Measured 2012 182 77 2013 359 69 6 6 M&I Resources Estimate (Near surface oxide zone) Deposit Cutoff (%TREO) Tonnes (106) Grade (%TREO) Grade %HREO (%CREO) Bull Hill + Whitetail 1.5 13.3 3.22 0.80 3.6 Whitetail 1.5 2.0 2.61 0.74 7.6 CREO defined as Nd, Pr, Eu, Dy, Tb, Y Based on M&I Resources from News Release dated March 18, 2013 7 7 Distribution of Whitetail Ridge Oxide Zone REEs Rare-Earth Element Lanthanum Cerium Neodymium Praseodymium Samarium Europium Gadolinium Wt-% Oxide Distribution(1) 25.3% 39.8% 18.8% 4.8% 3.7% 0.8% 2.6% Terbium 0.3% 6.4% Dysprosium 0.9% 10.8% Yttrium Total 2.5% 99.5% 1.7% 100.1% % Relative Value(2) 4.5% 7.9% 27.9% 7.6% 1.4% 29.6% 2.3% (1) Based on Inferred Resource from News Release dated 7 May 2012 (2) Based on January 1, 2013 prices of REEs 8 8 Inferred Resource Estimate (Near surface oxide zone) Deposit Cutoff (%TREO) Tonnes (106) Grade (%TREO) Grade (%CREO) %HREO Bull Hill + Whitetail 1.5 28.5 2.68 0.66 4.9 Whitetail 1.5 7.3 2.82 0.75 7.2 CREO defined as Nd, Pr, Eu, Dy, Tb, Y Based on M&I Resources from News Release dated March 18, 2013 9 9 Growing Bear Lodge District LeapFrog image showing the distribution of the +2% and +3% TREO grade shells in the greater Bull Hill area. 10 10 Soil and Rock Chip Geochemistry 11 11 Cutoff Grade Comparison M&I Near Surface Oxide Zone Cutoff Grade %TREO Resource Grade % TREO Tonnes Millions 1.0 2.6 19.3 1.5 3.2 13.3 3.0 4.7 5.4 4.5 6.5 2.1 Based on M&I Resources from News Release dated March 18, 2013 12 12 Hydrometallurgical Flowsheet 13 13 Location and Infrastructure • Good road system surrounding project • Low-cost, reliable power available • 64 km to nearest railhead; chemicals available • Skilled labor and water available • Favorable community acceptance; major coal mining center 97 km W • Top ranked mining jurisdiction(1) (1) Wyoming ranked as one of the top worldwide locations favorable for mining by the Fraser Institute and Behre Dolbear 14 14 NYSE MKT: REE & TSX: RES 15 15
