VANCOUVER, Oct. 22 /PRNewswire-FirstCall/ - Aurizon Mines Ltd. (TSX: ARZ; NYSE Amex: AZK) reports operating results for the third quarter of 2010 and provides the production outlook for the remainder of the year.

Aurizon plans to release its 2010 Third Quarter financial results before market open on Thursday, November 4, 2010 and management will host a conference call and live webcast that same day at 8:00 a.m. Pacific Standard Time (11:00 a.m. Eastern Standard Time) to allow analysts and shareholders the opportunity to hear management discuss the Company's quarterly results.

Third Quarter Production Results

Gold production for the third quarter of 2010 totaled 29,905 ounces from the processing of 169,913 tonnes at an average grade of 6.15 grams of gold per tonne, compared to ore grades of 7.0 grams of gold per tonne in the first half of 2010. As a result of the lower ore grades in the third quarter of 2010, mill recoveries were 89%, compared to 90.7% in the first half of 2010.

Challenging ground conditions in a localized area of Zone 113 resulted in changes to the mining sequencing, which adversely impacted expected ore grades. Additionally, as a result of the reduced availability of underground mining equipment due to mechanical issues, daily ore throughput decreased to 1,847 tonnes per day in the third quarter, compared to 2,005 tonnes per day in the second quarter of 2010. An independent study of maintenance practices and an evaluation of equipment replacement has been initiated to address this issue. Additional mining equipment was acquired in October to improve productivity.

Total cash costs were US$604 per ounce in the third quarter, compared to US$520 per ounce in the first half of 2010, primarily due to lower ore grades and higher unit mining costs. Unit operating costs on a Canadian dollar per tonne basis were $112 per tonne compared to $107 per tonne in the first half of 2010. Anticipated higher ore throughput for the balance of the year should reduce costs to approximately $110 per tonne in the fourth quarter.

Fourth Quarter Production Outlook

Based upon results for the first nine months and the revised mine plan for the balance of 2010, Casa Berardi production guidance has been lowered to 140,000 - 145,000 ounces, compared to previous guidance of 145,000 - 155,000 ounces of gold. Total cash costs for the full year are now estimated at approximately US$535 per ounce, assuming a Canadian dollar exchange rate of 1.01 against the U.S. dollar for the balance of the year, compared to previous guidance of US$500 per ounce at an exchange rate of 1.03.

Beginning in 2011 through 2013, annual gold production of 160,000 to 170,000 ounces is anticipated at total cash costs approximating US$450 per ounce, as the mine plan includes more areas containing material with the average underground reserve grade of approximately 8 grams of gold per tonne. It is anticipated that future mine plans will incorporate the results of the extensive drill programs currently in progress.

Quality Control

Information of a scientific or technical nature in this news release was prepared under the supervision of Martin Bergeron, P.Eng., Vice President, Operations and a qualified person under National Instrument 43-101.

Non-GAAP Information

Aurizon has included non-GAAP performance measures of total cash costs per ounce of gold and unit operating costs per tonne in this release. Aurizon reports total cash costs on a sales basis. In the gold mining industry, this is a common performance measure but does not have any standardized meaning, and is a non-GAAP measure. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Total cash costs per gold ounce are derived from amounts included in the statements of earnings and include mine site operating costs such as mining, processing and administration, but exclude amortization, reclamation costs, financing costs and capital development costs. The costs included in the calculation of total cash costs per ounce of gold are reduced by silver by-product sales and then divided by gold ounces sold and the average Bank of Canada Cad$/US$ exchange rate.

Unit operating costs per tonne is a non-GAAP measure and may not be comparable to data prepared by other gold producers. The Company believes that this generally accepted industry measure is a realistic indication of operating performance and is useful in allowing year over year comparisons. Unit operating costs per tonne is calculated by adjusting operating costs as shown in the Statement of Earnings for inventory adjustments and then dividing that by the tonnes processed through the mill.
