Avalon Announces New Senior Management Appointment and Provides Update on Nechalacho Feasibility Study

TORONTO, ONTARIO -- (Marketwire) -- 03/26/12 -- Avalon Rare Metals Inc. (TSX:AVL) (NYSE Amex:AVL) ("Avalon" or the "Company") is pleased to provide an update on progress on the Nechalacho rare earth elements feasibility study, Thor Lake, NWT, and to announce the appointment of Mr. Tim Butler as Vice President, Human Resources.


NECHALACHO FEASIBILITY STUDY UPDATE

Work on the Feasibility Study ("FS") on the Nechalacho rare earth elements project, being carried out by SNC-Lavalin, is progressing steadily and remains on target for completion at the end of 2012. Project permitting is also now proceeding on schedule and it is anticipated that the necessary permits will be in place to allow construction activities to begin in mid-2013. Negotiations toward reaching formal accommodation agreements with local Aboriginal groups are nearing completion.

The 40 tonne full scale pilot plant trial on Basal Zone ore was completed in February at SGS Minerals, Lakefield, Ontario. While final reports are pending, the two main objectives of the pilot plant were achieved. The primary objective was to produce a concentrate for the hydrometallurgical pilot plant and six tonnes of concentrate were successfully produced.

The second objective was to confirm previous flotation testwork results and identify opportunities for process optimization. Initial results indicate that the recoveries achieved were consistent with those achieved previously at the bench-scale, except for one sub-sample from the lowermost part of the Basal Zone where, as expected, observed textural differences in the ore resulted in reduced recoveries. Further work on the process flowsheet is required to optimize the recoveries from this material. The pilot plant trial also identified opportunities to simplify the reagent scheme and reduce costs.

A follow up flotation pilot plant trial on a two to three tonne sample has been scheduled for May 2012, with the objective of finalizing plant design parameters for the FS.

The results of the SNC-Lavalin prefeasibility study for the proposed separation plant are expected to be available in April 2012. The separation plant site selection process is also progressing.

The Mineral Resource update to incorporate all the 2011 Nechalacho drilling data is being carried out by Roscoe Postle Associates, Toronto, ON, and is also expected to be finalized in April 2012.
