Avalon Commences Exploration Drilling on East Kemptville Tin-Indium Project, Yarmouth Co., Nova Scotia

February 1, 2010

Toronto, ON -- Avalon Rare Metals Inc. (TSX:AVL, OTCQX:AVARF) (“Avalon” or the “Company”) is pleased to announce that it has commenced a 2,000 metre diamond drilling program on its exploration licences in the East Kemptville area, Yarmouth County, Nova Scotia. Ten holes are planned to test three target areas for tin-indium-copper-zinc mineralization similar to that of the past-producing East Kemptville tin deposit. Drilling commenced on January 18th and will continue for about three weeks. The Company is also re-evaluating the potential for renewed tin-indium production at the East Kemptville mine site in a Preliminary Economic Assessment (“PEA”), being conducted by Wardrop Engineering.

The East Kemptville deposit is a greisen, or hydrothermal replacement zone, associated with the contact of a regional granite intrusion known as the South Mountain batholith. This contact has been traced over a strike length of at least 10 km southwest from the mine site, where it is favourable for the occurrence of additional tin-indium-copper-zinc deposits. Limited outcrop exposure in the area necessitates the use of geophysical and geochemical methods to define drill targets. Several such targets have been defined through the compilation of historical data supplemented by new surveys completed intermittently by the Company over the past 18 months.

The top priority target is known as Gardner’s Meadows where a combined geophysical and geochemical anomaly company is supported by anomalous tin values reported from limited historical drilling. The anomaly was defined on the ground over an 800 metre strike length by recent induced polarization (IP) surveys, magnetics and soil surveys, using Mobile Metal Ion techniques (MMI). At least four holes will test this target. The entire work program has a budget of $500,000.

Growing demand for both tin and indium from the consumer electronics industry has resulted in strong prices and opportunities for new producers. In particular, tin is increasingly being used to replace lead in solders applied on electronic circuit boards due to lead toxicity issues. Europe, China and California have all recently passed laws requiring the use of lead-free solders in electronics, for which tin is the most economical and reliable substitute. Tin and indium are also used as an alloy in flat-screen display panels, while indium is alloyed with gallium in CIGS (Copper Indium Gallium Selenide) solar power panels, all of which are expanding markets.

Prices for tin have been quoted recently on the London Metal Exchange at over US$8.00/lb compared to less than US$2.00/lb when the mine ceased operations in 1992. Indium (99.99% purity) is currently trading at prices in excess of US$500/kg in China.

Drilling operations are being performed by Logan Drilling of Stewiacke, Nova Scotia under the field direction of consulting geologist Derek Thomas. Bruce Hudgins, P.Geo., Consulting Geologist and Avalon’s Vice-President, Exploration, William Mercer, Ph.D., P.Geo. are providing overall direction on the project. The qualified persons for the purposes of this news release are William Mercer and D.S. Bubar, P. Geo., President.
