Mineral Resources Increased At Casa Berardi 

VANCOUVER, BC - Aurizon Mines Ltd. reported that an updated mineral resource estimate has been completed for the Principal Area at its Casa Berardi Mine, in north-western Qubec. The updated mineral resource estimate was prepared by Scott Wilson Roscoe Postle Associates Inc ("Scott Wilson RPA") in collaboration with Aurizon's personnel.

The updated mineral resource estimate integrates the results of the 2009-2010 infill drill program that was completed last winter in the Principal Area. It will be included in the Pre-feasibility study of an open pit mining operation for the area that is currently in progress. The updated mineral resource estimate for the Principal Area includes the following: A 94% increase (335,000 ounces) of in-pit measured and indicated mineral resources to 5,345,000 tonnes at an average grade of 4.02 grams of gold per tonne or 690,000 ounces of gold (cut-off grade: 0.86 g/t) when compared to the previous estimate as at December 31, 2009;  A decrease of 6% (-10,000 ounces) in underground measured and indicated mineral resources outside the pit shell to 719,000 tonnes at an average grade of 6.99 grams of gold per tonne or 162,000 ounces of gold (cut-off grade of 4.0 g/t) when compared to the previous estimate as at December 31, 2009. The objectives of the infill drill program were to increase the quantity and improve the quality of the mineral resources previously defined in the Principal Area. "The measured and indicated mineral resources have been substantially increased in the Principal Area," said Martin Bergeron, P.Eng., Vice-President of Operations. "This will have a very positive impact on the Pre-feasibility study that is expected to be completed before the end of this year," he added.
