Aurizon Reports Further Positive Definition Drill Results from the Lower Inter Zone at Casa Berardi

Market Wire, September, 2006

Aurizon Mines Ltd. (TSX: ARZ)(AMEX: AZK) is pleased to present additional results from the ongoing definition drilling on the Lower Inter Zone at its 100 percent owned Casa Berardi Gold Project located in north-western Quebec, Canada. It is anticipated that operations at Casa Berardi will commence in the next 60 days.

"These additional definition holes drilled in the Lower Inter Zone continue to indicate that the potential of this wide, flat lying zone could improve our current mine plan," said David Hall, President and CEO of Aurizon. "The current undiluted resource grade for the Lower Inter Zone is 7.27 grams. A new resource estimate will be calculated for the deposits at Casa Berardi at the end of the year."

Definition drill program on Lower Inter Zone between section 10445 and 10595E

The Lower Inter Zone is a flat lying vein located 1,000 metres west of Zone 113. Definition drilling is ongoing to provide additional information required for the final mine plan. Mining of the Lower Inter Zone is expected in 2008.

Twelve (12) definition holes have been previously reported within this area and twenty-nine (29) additional definition holes have now been completed along the first 150 metre strike between sections 10445E and 10595E. Of the forty-one (41) holes drilled within the mineable reserve area, fifteen (15) holes, representing 37% of the holes drilled, have returned double digit grades (in grams). Best results are as follows.

(i) Previously released

Missing numbers in the sequence are shown on the sketch attached to this press release.

Information from the definition drilling will be used to outline the precise ore stope (mining) dimensions in the Lower Inter Zone. Footwall drifts, which are set 20 metres apart, are being used as the collar locations for the current drill program.

The foregoing information was prepared under the supervision of Michel Gilbert. P.Eng., Vice President of Aurizon, and a qualified person under National 43-101.

Quality Control

Core assays are performed on split or core sawed in half, with standard fire assay procedures and gravimetric finition. Certified reference material is inserted in the sample sequence for quality control. Assay checking on the pulp and reject samples are carried out systematically. Primary assaying is performed on site and check assays are carried out by ALS Chemex of Val D'Or, Quebec.

Drill hole planning, implementation and the quality control program is supervised by Jeannot Boutin, P.Eng., Superintendent Mining Geology, an appropriately qualified person as defined by National Instrument 43-101.

Additional Information

One sketch is attached showing the underground exploration progress. All other information previously released on the Casa Berardi Project, including the National Instrument 43-101 updated Feasibility Study prepared by Roscoe Postle & Associates Inc. dated October 26, 2005, is available on the Aurizon website at www.aurizon.com and www.sedar.com .
