Grade and thickness confirmed along the North Zone at Joanna
Aurizon Mines Ltd. (TSX: ARZ; NYSE Alternext U.S.: AZK) is pleased to announce the receipt of all assays from the recently completed infill drill program at its Joanna project, located 20 kilometres from Rouyn-Noranda, in north-western, Quebec.
Four hundred sixty-three (463) holes totalling 134,489 metres have been completed by Aurizon at Joanna, with the objective of confirming results from previous drilling and extending mineralized zones. Results from three hundred eighty-nine (389) holes have been previously released, and results from the last seventy-four (74) holes of the infill drilling program are included in this release.
As well as confirming continuity and grade outside the former indicated resources block outline, the new results confirm a significant thickness in the North Zone, inside the proposed pit outline (BBA Preliminary Assessment Report, see news release dated May 12, 2008 and report filed on under the Company's profile at www.sedar.com "BBA Preliminary Assessment").
Of the thirty eight (38) new holes that cross the western edge of the North Zone over a 200 metre area, twenty nine (29) holes returned intervals above 1.0 grams of gold per tonne over 20 metres (true thickness), including sixteen (16) holes with intervals greater than 1.0 grams of gold per tonne over 30 metres. The best results reported from the North Zone are as follows and include holes with a true thickness over 40 metres or grades over 3.0 grams of gold per tonne:

Of the remaining seventy four (74) holes, thirty seven (37) holes were planned to test the North Zone above 200 metres elevation and were not planned to intersect the South Zone. Results of the sixty four (64) holes representing one or more individual mineralized intersections with grades over 1.0 grams of gold per tonne over more than 5 metres are indicated on detailed tables attached to this news release. The details of ten (10) holes with grades below 1.0 grams of gold per tonne are not included in the table.
An additional table provides distinct intervals of 10 grams or more of gold per tonne.
A sketch showing the hole locations with intersections greater than 1.0 grams of gold per tonne over 35 metres and the drilling area in the North Zone is attached to this release.
<< East Block (Hosco) ------------------ >>
Infill drilling has been performed on a 25 metre by 25 metre spacing within the core of the East Block, previously known as the Hosco Zone as defined by BBA in the Preliminary Assessment. In this area, gold mineralization is located within different lenses located on both sides of the Cadillac break both dipping 55 degrees to the North. The South Zone, extending for more than 800 metres, corresponds to the entire length of the deposit. The North Zone is restricted to an extension of 400 metres. To date, 403 holes of 412 holes drilled on the East Block, successfully intersected mineralization above the cut off grade of 0.5 grams of gold per tonne as defined by the Preliminary Assessment report.
<< Preliminary Assessment Report ----------------------------- >>
The BBA Preliminary Assessment concluded that based upon the September 2007 mineral resources estimate for the East Block (Hosco) above the 200 metre level, the Joanna project is potentially feasible as a stand alone open-pit mine operation and recommended that additional work be undertaken to advance the project to the pre-feasibility stage. In addition, the report provided guidelines on the environmental risks.
Based on the preliminary pit optimization studies and mine design in the BBA report, the estimated diluted in pit resources contained in the detailed pit design are 9.08 million tonnes in the indicated mineral resource category at a grade of 1.5 grams of gold per tonne and 9.07 million tonnes in the inferred mineral resource category at a grade of 1.4 grams of gold per tonne, based on a cut-off grade of 0.5 grams of gold per tonne. The overall life of mine stripping ratio was estimated at 3.4 tonnes of waste per tonne of ore, with an inter-ramp pit slope of 55 degrees. Total metal recoverable was estimated at 653,000 ounces of gold assuming a mill recovery of 77%.
The BBA Preliminary Assessment is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the preliminary assessment will be realized. The basis for the Preliminary Assessment and the qualifications and assumptions for the report were previously provided in our May 12, 2008 news release.
Outlook
With the infill program now completed and all results received, a new resource estimate is currently being prepared by SGS Geostat Ltd. Aurizon has appointed BBA to prepare the pre-feasibility study upon completion of the updated resource estimate. Other contracts have been awarded to the following companies: Roche Ltd., to complete the required environmental studies, Golder Associates, the rock mechanic evaluation of the pit design, and SGS Lakefield Research Limited, the metallurgy processes. The pre-feasibility study will include the results of the expanded drill program, resource modeling, rock mechanic modeling, environmental studies and the metallurgical testworks that are presently in progress. Aurizon estimates that the pre-feasibility study should be completed by late in the second quarter, 2009.
Two rigs are currently active on the property, testing high grade potential along the dip extension below 700 metres, and geophysical and geochemical targets outside of the main orebody, including the recently optioned Alexandria property located along the eastern extension of the Joanna deposit.
Quality Control
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 reject are carried out on approximately 10% of samples. For additional information on Quality Assurance and Quality control ("QA/QC"), refer to the previously mentioned BBA Preliminary Assessment Report. Exploration primary assaying was performed at ALS Chemex of Val d'Or and check assays were carried out by Laboratoire d'Analyse Bourlamaque of Val d'Or. ALS Chemex is a fully accredited laboratory under ISO 9001-2000 standards, and Laboratoire d'Analyse Bourlamaque is in the process of obtaining ISO-9001-2000 certification.
Drill hole planning, implementation and the quality control program is supervised by Martin Demers P.Geo., Exploration Manager, a "qualified person" as defined by National Instrument 43-101. Mr. Demers is also responsible for the scientific and technical information in this news release.

CAUTIONARY NOTE TO US READERS
As a British Columbia corporation, the Company is subject to certain rules and regulations issued by the British Columbia Securities Commission ("BC Securities Commission"). The Company is required to provide detailed information regarding its properties including mineralization, drilling, sampling and analysis, security of samples and mineral resource and mineral reserve estimates. Further, the Company describes mineral resources associated with its properties utilizing terminology such as "indicated" or "inferred" which terms are recognized by Canadian regulations but are not recognized by the United States Securities and Exchange Commission ("SEC").
Cautionary Note to U.S. Investors Regarding Mineral Resources
The SEC allows mining companies, in their filings with the SEC, to disclose only those mineral deposits they can economically and legally extract or produce. The Company may use certain terms in this document, such as "mineral resources", "indicated mineral resources" and "inferred mineral resources" that are recognized and mandated by Canadian securities regulators but are not recognized by the SEC.
This News Release may use the term "indicated" mineral resources. U.S. readers are cautioned that while that term is recognized and required by Canadian regulations, the SEC does not recognize it. U.S. investors are cautioned not to assume that any part or all of mineral deposits in this category will ever be converted into mineral reserves.
This News Release may also use the term "inferred" mineral resources. U.S. readers are cautioned that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
