Aurizon Mines Ltd.: New Drill Results Highlight the Potential to Extend the Principal Zone at the Casa Berardi Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 15, 2013) - Aurizon Mines Ltd. (TSX:ARZ)(NYSE MKT:AZK) is pleased to report exploration drill results east of the Principal Zone within Zone 134 at its Casa Berardi Mine in north-western Quebec.

The objective of this drill program, which concluded in 2012, was to investigate the immediate extension of the Principal Zone eastward, along the Casa Berardi Fault. The program was focused between surface and a depth of 300 metres, approximately 1.2 kilometres east of the West Mine shaft, and was comprised of 54 holes for a total of 22,587 metres of drilling from both surface and underground. The holes are located between sections 12700 and 13550. Zone 134 has been outlined by historic holes over an area of approximately 500 metres along strike.

This news release focuses on results from the 19 holes that intersected the Casa Berardi fault.

Five of the 19 holes returned intervals with a metal factor (true width in metres x the grade in grams of gold per tonne) of 15 or higher of which four were between surface and to a depth of 165 metres. This suggests lateral continuity of the lenses in the trend along the Casa Berardi fault to a depth of 300 metres in close proximity of the Principal Zone.

The remaining 35 holes were drilled at least 200 metres north of the Casa Berardi Fault and intersected the Principal Zone structure. These results indicate that mineralization can been found along oblique structures north of the Casa Berardi Fault which may allow the Principal Pit outline to be extended.

"These results are encouraging as they suggest further open pit and underground potential at the Principal Zone along the Casa Berardi fault," said George Paspalas, President and CEO of Aurizon Mines. He added, "These results will also allow us to target additional drilling with the potential to increase resources at the mine near existing reserves. The program will also include infill drilling with the objective of confirming continuity of mineralization across the potentially expanded pit area."

The best results are:

CBS-12-478 7.7 grams of gold per tonne over 4.2 metres
CBS-12-486 1.7 grams of gold per tonne over 96.3 metres including 4.8 grams of gold per tonne over 7.2 metres
CBS-12-488 52.9 grams of gold per tonne over 3.6 metres including 148.1 grams of gold per tonne over 1.1 metres;
1.4 grams of gold per tonne over 10.6 metres,
3.4 grams of gold per tonne over 2.4 metres
CBS-12-527 1.5 grams of gold per tonne over 10.6 metres
CBP-12-414 5.9 grams of gold per tonne over 2.8 metres
Note: All intersections represent true width. Complete results are shown in the attached tables.

In Zone 134, gold mineralization occurs in quartz veins, stockworks and disseminated sulphide bearing structures. The mineralization is located close to the Casa Berardi fault in a volcanic-sedimentary environment.

"The outline of a new mineralized system within Zone 134 supports the potential for continuity of mineralization toward the east, in an area that had not previously been thoroughly investigated. Based on these new results and our current understanding, we are optimistic that clusters of mineralized lenses and new resources can be found with additional drilling," said Gilles Carrier P. Eng., Principal Exploration Geologist, Casa Berardi Mine.


Based on these results and given that Zone 134 is open laterally in every direction and at depth, an infill program has been initiated to confirm the best results and tighten the spacing to 50 metres. In addition, a drill rig is currently conducting step-out drilling along the western extension of the East Mine Pit centered on section 14600.

Quality Control and Qualified Person

Core assays are performed on core sawed in half, with standard fire assay procedures and atomic absorption finition. Certified reference material, duplicate and blanks are inserted in the sample sequence for quality control. Assay checking on pulp and coarse rejects are carried out on approximately 5% of samples. Additional information on Quality Assurance and Quality Control ("QA/QC") can be found in the "Technical Report on the Casa Berardi Mine", dated March 28, 2011 which can be found under Aurizon's profile on Primary exploration assaying was performed at the mine site laboratory and at Swastica lab in Ontario. The QA/QC program is performed at ALS Chemex lab in Val d'Or.
