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
