Aurizon Mines Ltd.: Drilling Confirms the Continuity and the Potential Extension of the 123 Zone at the Casa Berardi Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 6, 2011) - Aurizon Mines Ltd. (TSX:ARZ)(NYSE Amex:AZK) is pleased to report initial encouraging results from drilling of the 123 Zone from the exploration track drift on the 550 metre level at its Casa Berardi Mine in north-western Quebec.

The current exploration program is focused 200 metres below and above the 550 metre on Zone 123, located approximately 1.0 kilometre east of the West Mine shaft, with the objective to delineate the continuity of the mineralization.

Forty nine (49) new holes have been completed from the 550 metre level track drift. The program is targeting a series of south-east dipping lenses where mineralized structures were previously identified from drilling at the 280 metre level.

Twenty three (23) mineralized intervals out of the forty nine (49) holes returned a metal factor of 10 (true width in metres x the gold grade in grams per tonne), or higher which indicates lense continuity in the trend of the mineralized corridor. These drill holes are included in this release and are illustrated on the attached sketches. The drilling program covered an area of 300 metres along strike, 400 metres in width and up to 200 metres below and above the 550 metre level.

The best results were 23.3 grams of gold per tonne over 6.7 metres (true width) in hole CBP-0283 and 15.2 grams of gold per tonne over 8.5 metres (true width) in hole CBP-0272, respectively. Thirty five (35) of the forty nine (49) holes were drilled outside the inferred resource block located between the 280 metre level and the 550 metre level.

In Zone 123, gold mineralization occurs in quartz veins, cherty units and massive sulphide structures located between the South break to the east and the South break to the west in a volcanic-sedimentary bearing environment. This corridor covers more than 400 metres in width, and up to 250 metres within the same lense.

As at December 31, 2010, the 123 Zone contained mineral reserves of 493,000 tonnes at a grade of 7.4 grams of gold per tonne, representing 117,700 ounces; indicated mineral resources of 136,000 tonnes at a grade of 5.4 grams of gold per tonne, representing 23,700 ounces and inferred mineral resources of 909,000 tonnes at a grade of 8.0 grams of gold per tonne, representing 234,100 ounces.

"The continuity in the mineralized system of Zone 123 confirms the potential to extend the mineralization towards surface and at depth, thereby increasing the potential to find more mineralized lenses within this structure," said Gilles Carrier P. Eng., Principal Exploration Geologist.


Based on these encouraging initial results, underground in-fill drilling will be intensified with the addition of three drill rigs from the 550 and 810 metre exploration track drifts to define the down dip and the up-dip extensions of the zone. An updated mineral resource estimate will be completed as of December 31, 2011.

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 a performed at ALS Chemex lab in Val d'Or.

Information of a scientific or technical nature included in this release has been prepared under the supervision of Gilles Carrier, P. Eng., Principal Exploration Geologist of Aurizon and Qualified Person under NI 43-101.

Except as required under applicable securities legislation, the Company does not intend, and does not assume any obligation, to update this forward-looking information. Forward-looking information includes, but is not limited to, statements with respect to mineral reserve and mineral resource estimates, the, anticipated effect of completed drill results on the Casa Berardi project, planned work programs, strategic plans and expected outcomes. Often, but not always, forward-looking information can be identified by the use of words such as "plans", "expects, "is expected", "budget", "scheduled", "estimates", forecasts", "intends", "anticipates", or "believes", or the negatives thereof or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might", or "will" be taken, occur or be achieved.

The forward-looking information contained in this news release is based on certain assumptions that the Company believes are reasonable, including, with respect to mineral reserve and resource estimates, the key assumptions and parameters on which such estimates are based, as set out in the technical report for the property, that the current price of and demand for gold will be sustained or will improve, the supply of gold will remain stable, that the general business and economic conditions will not change in a material adverse manner, that financing will be available if and when needed on reasonable terms and that the Company will not experience any material accident, labour dispute, or failure of plant or equipment.

However, forward-looking information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include, among others, conclusions of economic evaluations, the risk that actual results of exploration activities will be different than anticipated, that cost of labour, equipment or materials will increase more than expected, that the future price of gold will decline, that the Canadian dollar will strengthen against the U.S. dollar, that mineral resources and reserves are not as estimated, that actual costs or actual results of reclamation activities are greater than expected; that changes in project parameters as plans continue to be refined may result in increased costs, of unexpected variations in mineral resources and reserves, grade or recovery rates, of failure of plant, equipment or processes to operate as anticipated, of accidents, labour disputes and other risks generally associated with mining, unanticipated delays in obtaining governmental approvals or financing or in the completion of development or construction activities, as well as those factors and other risks more fully described in Aurizon's Annual Information Form filed with the securities commission of all of the provinces and territories of Canada and in Aurizon's Annual Report on Form 40-F filed with the United States Securities and Exchange Commission, which are available on Sedar at and on Edgar at Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results to not be as anticipated, estimated or intended.
