Aurizon Reports High Grade Results at Joanna

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 10, 2007) - Aurizon Mines Ltd. (TSX:ARZ)(AMEX:AZK) is pleased to report that surface exploration drilling has intersected narrow veins with high gold grades along the western extension of the Heva block at its Joanna Property, located twenty kilometres east of Rouyn in north western Quebec, Canada.

Ten (10) of the twenty-two (22) holes completed along the western extension returned grades above 7.0 grams of gold per tonne over an average width of 1.3 metres, including six (6) holes above 13.0 grams of gold per tonne. The best results are as follows:

At Joanna, mineralization follows multiple distinct zones along a dip between 50 and 60 degrees to the north with a western plunge. The mineral resources are estimated at 11.3 million tonnes averaging 1.7 grams of gold per tonne, for 630,000 ounces in the indicated mineral resource category and 28.6 million tonnes averaging 1.6 grams of gold per tonne, for 1.42 million ounces in the inferred mineral resource category.

Current mineral resources are restricted to a 100 to 190 metre wide lower grade halo of 0.5 to 2.0 grams of gold per tonne. Mineralized zones along this corridor plunge to the west, and are usually narrower and less continuous in the western block and wider and more continuous in the eastern block.

Three drill rigs are currently active at Joanna with an objective to:

- upgrade the existing inferred mineral resource to the indicated category on the eastern block where the corridor is wider;

- test the extension of the mineralized corridor outside of the existing mineral resources contour; and

- test the high grade potential along the dip extension of the main corridor on the eastern block.

The deep exploration program will test the potential for higher grade zones. Drilling was initiated closer to the surface, west of the western block, where access for drilling was readily accessible.

As high grade veins have now been intersected where the mineralized corridor was narrower, the rig will move further east where a larger and more continuous mineralized corridor has been discovered. Drilling will be initiated as soon as drill access is completed with the objective of drilling down to depths of 700 metres below surface.

"The intersection of high gold grades on our Joanna property is encouraging and validates our initial objective of testing for high grade potential to depth," said Martin Demers, P. Geol. Exploration Manager. "We look forward to testing this high grade potential by drilling under the wider mineralized corridor to the east."

"The combination of potential high gold grades to depth, together with the existing low grade near surface resource, could have a positive impact on future development of the project," added David Hall, President.

Quality Control

Core assays are performed on core sawed in half, with standard fire assay procedures and atomic absorption finition or gravimetric finition for initial assay above 1000 ppb. All samples with visible gold observed are double checked by a metallic sieves gold concentration. Certified reference material is inserted in the sample sequence for quality control. Assay checking on the pulp and reject samples is carried out systematically. Exploration primary assaying is performed at Labexpert of Rouyn-Noranda and check assays on mineralized intervals will be carried out by ALS Chemex of Val D'Or, Quebec.

Information of a scientific or technical nature in this news release, work, sampling, implementation and the quality control program has been prepared by or under the supervision of Martin Demers, P.Geol., Exploration Manager, a qualified person as defined by National Instrument 43-101.

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 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" 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" 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.
