LAKEWOOD, COLORADO -- (Marketwire) -- 03/18/13 -- Rare Element Resources Ltd. (NYSE Amex: REE)(NYSE MKT: REE)(TSX: RES) (the "Company") reports that it has filed its transitional report and audited consolidated financial statements on Form 10-K for the six months ended December 31, 2012 on www.sec.gov and www.sedar.com. The transitional report is filed following the Company's change in fiscal year-end from June 30 to December 31 and reports the six month period ending December 31, 2012.

As to the financial report filing, Randall J. Scott, President and Chief Executive Officer stated, "We are pleased at the overall position of the Company at the end of 2012 and into 2013. The recently announced a 65% increase in our Measured and Indicated resource at Bear Lodge with its strong Critical Rare Earths content, the progress on the proprietary oxalate process, and a healthy cash balance provides an excellent basis for continued progress towards the Bear Lodge REE project Feasibility Study."

Update on the Bear Lodge REE Project:

Resource Estimate Update

The Company's Form 10-K and recent press release regarding updated resource estimates announced 14.7 million tons grading 3.22% REO at 1.5% cutoff grade. The Company is preparing an updated National Instrument 43-101 ("NI 43-101") report, which will be filed and available under the Company's SEDAR profile at www.sedar.com within the timeline required by NI 43-101.

Dr. James Clark, Vice President of Exploration for the Company, states "We are extremely pleased with the substantial increase in our estimated M&I Resource at Bear Lodge, as well as the further confirmation of the continuity of the Bull Hill REE deposit and the Whitetail Ridge resource area. The increased M&I resources in those deposits will be incorporated into the upcoming Feasibility Study. Further, the results we have reported confirm the zones of HREE-enrichment (Eu, Tb, Dy, and Y) at Whitetail Ridge and Carbon and illustrate the growing significance of this world-class source of CREOs."

Metallurgy and Project Development

Earlier this year, a coordinated effort of the Company's geologists and metallurgists provided a selection of eleven sample sites that exhibit variable mineralogy and are spatially representative of the expanded mine footprint. SGS Lakefield completed confirmatory metallurgical testwork and provided additional design data.

Mountain States Research and Development (MSRDI), under the direction of Dr. Roshan Bhappu, has conducted HREE testwork on sample material from the Whitetail Ridge, Carbon and East Taylor areas. Physical upgrading methods as well as hydrometallurgical processing have been applied in the testwork. Based on these results, results from exploration drilling at Whitetail Ridge, and preliminary drilling at Carbon and East Taylor, we have determined to integrate the development of the Whitetail Ridge HREE-enriched area into the FS and permitting timeline for the Bear Lodge REE Project. Inclusion of the Whitetail Ridge zone in the FS may provide enhanced project economics.

Bulk sampling of oxide mineralization from large diameter drill core and from surface trenches took place in during the 2010, 2011 and 2012 exploration drilling programs on the Bear Lodge property.

Oxalate purification process

The Company is further progressing the lab scale testwork on our proprietary process technology that is designed to enhance the efficiency of rare earth recovery in concentrates. As previously announced, the new metallurgical process produces a high purity REO concentrate and is designed to increase recoveries, reduce raw material requirements, and enhance the Company's ability to upgrade final rare earth products. Following the completion of the testwork, the proprietary process technology will be in incorporated into our planned pilot plant testwork, leading to the formal start of our FS.

Tests on the high-grade oxide mineralization indicate a total recovery of 81% of REO is expected using a two-stage process. The first stage is mineral concentration, also known as physical upgrading ("PUG").

The rare earth ore from the Bull Hill mine will be upgraded physically on site to produce the REE-rich pre-concentrate solids for treatment at the hydrometallurgical facility in Upton, Wyoming. The hydrometallurgical process will employ a hot chloride solution to extract over 90% of the REEs into a pregnant leach solution (PLS). Using closed reactor vessels, the PLS will react with oxalic acid powder under optimized conditions to facilitate selective precipitation of REEs.

The REE-rich oxalate precipitates are converted to their oxide form in a calcination process. The mass of REE-oxalates is reduced by as much as 50% and the calcine powder contains 90+% pure mixed REO. This is a significant improvement from the 45% concentrate which was used as the basis for the economic calculation in the Pre-Feasibility Study (PFS) completed in 2012. The REO powder can be re-dissolved selectively in an appropriate acid to isolate traces of residual impurities.

Project Schedule

With the updated resources announcement, continued drilling program, advanced metallurgical testwork, ongoing strategic partner and off-take discussions, environmental and social impact studies well underway, we are poised to further advance the project in 2013 as planned, including the commencement of the FS in mid-2013.

Quarter Ended December 31, 2012 Financial Highlights:

Please note that financial results published by the Company are all stated in U.S. Dollars.

As an exploration company, we do not have revenues at this time. The net loss for the quarter ended December 31, 2012 totaled $9.6 million or $0.21 per share as compared to a net loss of $10.1 million or $0.23 per share for the same period in 2011. The $0.5 million positive variance in net loss between the periods was due to the following:

-- Increased exploration spending of $1.0 million at the Bear Lodge property;-- Positive variance in stock-based compensation of $2.1 million due primarily to a lower share price and smaller number of options granted;-- Positive variance of $0.9 million in write-downs of exploration properties;-- Negative variance of $1.2 million in foreign exchange due to the impacts on the Company's Canadian dollar cash balances related to exchange rate fluctuations in the US dollar on the balance sheet date; and-- Negative variances of $0.2 million in other non-operating income and expenses.



Cash and cash equivalents, and short-term investments at December 31, 2012 were $40.1 million. The decrease in cash and investments in the quarter ended December 31, 2012 was $7.2 million and was primarily due to exploration, corporate administrative costs, and foreign exchange losses on our Canadian cash balances.

Six Months Ended December 31, 2012 Financial Highlights:

The net loss for the six months ended December 31, 2012 totaled $15.4 million or $0.35 per share as compared to a net loss of $21.1 million or $0.48 per share for the same period in 2011. The $5.6 million positive variance in net loss between the periods was due to the following:

-- Increased exploration spending of $2.6 million at the Bear Lodge property;-- Increased corporate administration spending of $0.8 million due primarily to an increase in the number of employees;-- Positive variance in stock-based compensation of $4.4 million due primarily to a lower share price and smaller number of options granted;-- Positive variance of $0.9 million due to prior period write-downs of exploration properties;-- Positive variance of $4.1 million in foreign exchange due to the impacts on the Company's Canadian dollar cash balances related to exchange rate fluctuations in the US dollar on the balance sheet date; and-- Negative variances of $0.4 million in other non-operating income and expenses.



Cash and cash equivalents, and short-term investments decreased $11.6 million for the six months ended December 31, 2012. The decrease in cash and investments was primarily due to spending for exploration, corporate administrative and Bear Lodge development related costs, offset by positive impacts from foreign exchange changes on translating our Canadian cash balances to U. S. dollars, working capital changes, interest income, proceeds from option exercises and releases of restricted cash.
