Liberty Provides Pre-Feasibility Study for the Redstone Nickel Mine
Edmonton, Alberta CANADA, January 11, 2010 /FSC/ - Liberty Mines Inc. (TSX: LBE), ("Liberty or the Company") is pleased to announce the results of an independent National Instrument 43-101 compliant pre-feasibility study completed by SRK Consulting (Canada) Inc. ("SRK") for the Redstone nickel mine. The study includes deep drilling to the 1150m level from surface and data from drilling within the mine completed in April 2008 which was not included in the interim technical report dated December 16, 2008.
The Redstone mineral resource estimate by SRK at a cut-off grade of 0.51% nickel ("Ni") consists of 599,000 tonnes in the Measured and Indicated categories grading 1.47% Ni and 0.02% copper ("Cu"); and 737,000 tonnes in the Inferred category grading 1.57% Ni and 0.03% Cu. The Proven and Probable Mineral Reserves were estimated at 259,900 tonnes with an average grade of 1.04% nickel ("Ni") using a nickel price of US$15,430 per tonne (US$7.00 per pound) and an exchange rate of $1.00 CDN =
.90 US. All revenue and costs are expressed in Canadian dollars unless otherwise indicated.
Some of the important points in the technical report are:
* Innovative mining methods, successful exploration and the realization of the significant mineralization in the hangingwall structures of the Redstone Mine has greatly enhanced its economics;
* There is a strong potential to increase the Inferred Resources in the lower zone between 510m and 1150m; and to upgrade the current Inferred resources to the Indicated category with additional drilling. The reserves would be positively increased and the life of mine ("LoM") extending accordingly;
* SRK estimates a mine life of 26 months with an average ore mining production rate of 10,000 tonnes per month (500 t/d with 5 days of operation per week);
* The undiscounted pre-tax LoM cash flow is estimated at $2.9 million;
* Sublevel longhole retreat (15 metre vertical spacing) is the preferred method for mining the underground disseminated mineralization;
* The sublevel longhole retreat mining cost is $38.47/tonne;
* The estimated unit cost for processing at 1,800 tpd (Redstone & McWatters combined) is $14.81per tonne milled;
* The use of a proven electric monorail system below 1600 level will complement diesel trucking above the 1600 level while enhancing capital and operating costs;
* The monorail system provides an opportunity if the mine production rate is ever increased as it doesn't have the same ventilation or interference issues as diesel trucks.
The resource and reserve estimates for the Redstone mine are presented in the following tables, respectively:

* Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Reported at 0.51% nickel cut-off. Cut-off grades are based on a nickel price of US$7.00/lb and on a mill recovery of eighty-seven percent. All figures have been rounded to reflect the accuracy of the estimate.
