Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF OPERATIONS	Rare Element Resources Ltd. (collectively, “we,” “us,” “our,” “Rare Element” or the “Company”) was incorporated under the laws of the Province of British Columbia on June 3, 1999. We are currently in the process of exploring and evaluating the Bear Lodge Rare Earth Element (“REE”) Project in Wyoming. The Bear Lodge REE Project is located within our Bear Lodge Property which also includes the Sundance Gold Project. In accordance with U.S. GAAP we are an exploration stage entity. We have completed a pre-feasibility study on the Bear Lodge REE Project and have begun compiling data for the preparation of a feasibility study. To date, we have no revenue and have an accumulated operating deficit of $81,590 of which $43,018 is attributable to the exploration of our mineral interests. Our continuing operations and the recoverability of the carrying values of our mineral property interests are dependent upon economic reserves being discovered and developed at the Bear Lodge REE Project, our ability to obtain the necessary permits to mine the Bear Lodge REE Project and on future profitable production or proceeds from the disposition of any of our mineral property interests. Development and/or start-up of the Bear Lodge REE Project is dependent upon our ability to obtain the necessary financing to complete the exploration, development and/or start-up of the Bear Lodge REE Project. Although we have been successful in raising such capital in the past, there can be no assurance that we will be able to do so in the future. A write down in the carrying values of one or more of our mineral properties may be required in the future as a result of events and circumstances, such as our inability to obtain all the necessary permits, changes in the legal status of our mineral properties, government actions, the results of technical evaluation and changes in economic conditions, including the price of rare-earth oxide (“REO”) concentrate and other commodities or input prices. We regularly evaluate the carrying value of our mineral properties to determine if impairment is required in view of such factors.
