11 February 2011 New Mineralized Extension at LIMâs Houston Deposits Increases Houston Resource to 20 Million Tonnes  Anglesey Miningâs 41% owned associate Labrador Iron Mines Holdings Limited (TSX: LIM) is pleased to report a new resource estimate for its 100% owned Houston deposits located in western Labrador following the 2010 exploration drilling program. The new resource estimate of 19,499,000 million tonnes of measured and indicated resources represents a significant increase over previous estimates. Commenting on the increased resource estimate at the Houston deposits, John F.

Kearney, Chairman and CEO of Labrador Iron Mines said, âAs a result of the exploration success and this significant increase, the Houston deposits are now of sufficient tonnage to merit evaluation of a stand-alone operation. We are now assessing the development of a new separate âSouth Central Zoneâ, with its own dedicated processing plant, which, subject to environmental assessment and permitting, could be brought into production in 2013 at an output rate of 2 to 3 million tonnes of iron ore per year. This would be in addition to LIMâs existing processing plant at Silver Yards which will have a similar design capacity.â The Houston 1, 2 and 3 deposits comprise 12 mineral rights licenses representing 112 mineral claim units that cover approximately 2,800 hectares, situated 15 km south-east of LIMâs James Mine and Silver Yards processing area and approximately  20 km from the town of Schefferville, Quebec. The Houston deposits form part of the Stage 1 planned production at LIMâs Schefferville area direct shipping iron ore projects. The new estimate, prepared in accordance with NI 43-101, represents an increase in tonnage of over 25% from the previous NI 43-101 estimate announced in April 2010 and more than double the historical resource (not NI 43-101 compliant) previously estimated by the Iron Ore Company of Canada (IOC) prior to 1982. The new resource also includes about one million tonnes of manganiferous ore (Mn) grading about 54.4% Fe and 5% manganese. _The Houston Deposits âResource Summary â February 2011 (See attached table for details)_
 The updated resource estimate for the Houston deposits is based on an additional 1,804 metres of drilling in 26 holes and 625 samples carried out by LIM in 2010. The majority of the additional resource has resulted from the drilling of a new mineralized zone located between the Houston 1 and 2 deposits, as well as in-fill drilling within the deposit outlines during 2010. The Houston deposits remain open along strike particularly to the southeast and further drilling is planned on Houston 3 during 2011. The classification of resources was completed using the results of drilling and trenching carried out by LIM during the 2006 to 2010 field seasons, which comprised twinning, in-fill and step-out drilling and trenching, as well as drill and trench data previously obtained by IOC. Block Modeling LIM used Gemcom GEMS 6.4.2.1 software for the resource estimation.

The ordinary kriging interpolation method was used to estimate the resources by block modeling with block sizes of 5x5x5 metres and block rotation of 45.6° which matches with the general strike of the deposit.

LIM used the geological and ore models interpreted in plane and in sections.

LIM used different search ellipses derived from 3D semi-variogram analyses for the classification of the resources. Analyses Analyses for all of the samples from the 2006 to 2010 drilling and trenching programs were carried out by SGS-Lakefield Laboratory and Activation Laboratories.

The analytical method used was borate fusion whole rock X-Ray Fluorescence.
