Aurizon Mines Ltd.: Deeper Drilling at Marban Reveals Added Upside With 5.3 Grams of Gold Per Tonne Over 12.8 Metres07:01 EDT Wednesday, June 22, 2011VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 22, 2011) -Editor's Note: There is one image associated with this press release.Aurizon Mines Ltd. ("Aurizon") (TSX:ARZ)(NYSE Amex:AZK) is pleased to report the latest drilling results at the Marban Block property, located in the Malartic gold camp, Abitibi region of Quebec.Highlights from 23 new drill holes include 5.3 grams of gold per tonne over 12.8 metres (MB-11-191) obtained along the depth extension of the footwall shear zone at the Marban deposit at approximately 400 metres below surface. The intersection has opened up significant potential to increase the gold resources at depth at Marban.Highlights of Marban deposit drilling results:37.1 grams of gold per tonne over 1.4 metres (MB-11-182);5.3 grams of gold per tonne over 12.8 metres(MB-11-191);5.1 grams of gold per tonne over 6.0 metres(MB-11-192).Highlights of Norlartic deposit drilling results:3.0 grams of gold per tonne over 14.4 metres (NL-11-049).Aurizon's initial program commenced on August 30, 2010 and includes 50,000 metres of diamond drilling. Three drill rigs are currently in operation on the project. To date, 152 holes and five (5) extensions of previous holes have been completed for a total of 40,888 metres. Results from 92 holes have been previously released, results from 23 holes are included in this release, and results are pending for 42 completed drill holes."With these new series of holes, higher grade results become more important and increase our knowledge in an area located about 200 metres below the former mining operations. A higher grade distribution inside pluri-metric intervals provides a strong incentive to start exploring at depth," said Martin Demers, P.Geo. Exploration Manager of Aurizon. Marban deposit drilling One hundred and fifteen (115) holes and five (5) extensions of previous holes, for a total of 33,325 metres, have been completed on the Marban deposit since the start of the program in August 2010. Results for 76 holes (MB-10-102 to -175, MB-06-002ext and MB-07-005ext) were previously released. Results received for an additional 17 holes (MB-11-176 to -192) are tabled on the following pages. Results are pending for 27 holes.The first phase of drilling at Marban was mainly focused on drilling at 50 metre spacings, within the top 300 metres from surface over a 1,050-metre strike length of the Marban gold mineralised system. Drilling has now shifted to deeper drilling to test the down dip extension of the mineralised zones, mainly from 300 to 500 metres vertical depth, as well as select in-fill drilling at 25-metre spacings.Two significant gold mineralised intersections were obtained along the down dip extension of a major shear zone recognised along the footwall (south) contact of the Marban Mine Sequence. The footwall shear is sparsely investigated below 300 metres vertical depth over the 1.4 kilometre strike length of the Marban gold mineralised system. Hole MB-11-191, located on section 4+00 E, returned a gold mineralised intersection of 5.3 grams of gold per tonne over 12.8 metres from the footwall shear at a vertical depth of 420 metres. Hole MB-11-192 cut the same zone at a vertical depth of 380 metres, 40 metres above the intersection in hole MB-11-191. The zone in hole MB-11-192 averaged of 5.1 grams of gold per tonne over 6.0 metres. These intersections have opened up significant upside to increase the gold resources at depth at Marban. Norlartic deposit drilling Twenty-one (21) drill holes (4,319 metres) were completed on the Norlartic deposit during the winter. Results for 15 holes (NL-11-040 to -045 and -047, -052 to -057, -059 and -060) were previously released. Results for the final six (6) holes (NL-11-048, -049, -058, and -061 to -063) are tabled on the following pages.This initial phase of drilling at Norlartic served to better define the entire width of the Norbenite shear gold mineralised envelope within the top 200 metres from surface, and more specifically along the western 500-metre strike length of the Norlartic deposit. Best results of the 21-hole program include:3.1 grams of gold per tonne over 10.7 metres (NL-11-040); 6.8 grams of gold per tonne over 4.6 metres (NL-11-042); 1.9 grams of gold per tonne over 58.3 metres (NL-11-047);3.0 grams of gold per tonne over 14.4 metres (NL-11-049);7.4 grams of gold per tonne over 9.3 metres (NL-11-052); 5.6 grams of gold per tonne over 6.7 metres (NL-11-054);2.1 grams of gold per tonne over 28.0 metres (NL-11-057);10.8 grams of gold per tonne over 3.0 metres (NL-11-059);3.1 grams of gold per tonne over 10.9 metres (NL-11-060). Fence drilling between Norlartic and Marban deposits Sixteen (16) drill holes (3,244 metres) have been completed to date to investigate the southeast strike extension of the Norbenite shear, which hosts the Kierens and Norlartic deposits. Results were previously released for one hole NL-11-046 that returned an interval of 21.2 metres averaging 1.23 grams of gold per tonne intersected along the southeast extension of the Norlartic deposit. The remaining holes will be released once all assay results are received and interpretation of the sector is completed.

The initial 50% interest can be earned by incurring expenditures of C$20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold is the project operator during the initial earn-in period (see news release dated July 6, 2010). Technical Info, QA/QC and Qualified Persons Reported intervals are in core lengths but are anticipated to approximate true width, except where structural complexities occur, as the holes were drilled perpendicular to the principal local structural orientation.Diamond drill holes were drilled with NQ-size core in order to obtain larger sample volumes of the mineralised zones, except for holes that traversed underground workings which were completed using BQ-size core. The core was sealed and delivered by the drilling contractor to NioGold's facilities located at the Norlartic mine site. The core was photographed for reference, logged and mineralised sections were sawed in half. Sample lengths vary between 0.5 to 1.5 metres. Half core samples were bagged, sealed and delivered to ALS Chemex in Val-d'Or, Quebec, an accredited laboratory. The remaining core is stored on site for reference. Samples were assayed by the fire-assay method using an atomic absorption finish on a 50-gram pulp split. A quality assurance and quality control program (QA/QC) was implemented by NioGold and the laboratory to insure the precision and reproducibility of the analytical method and results. The QA/QC program includes the insertion of standards, blanks and field duplicates in the sample batches sent to the laboratory and a systematic re-assaying of samples returning values above 2 g/t Au by the fire-assay method using a gravimetric finish. As well, pulps grading above 0.5 g/t Au are sent to Bourlamaque Assay Laboratories Ltd. in Val-d'Or for check assaying.The drilling program was conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), a Qualified Person as defined by National Instrument 43-101. This news release was prepared under the supervision of Martin Demers, P. Geo., Exploration Manager of Aurizon and a Qualified Person under. National Instrument 43-101, based on information made available by Niogold and verified by personnel of Aurizon.Additional InformationThe attached sketch shows the geological context of the Marban Block property, the position of the drill holes and a plan view of the Marban deposit.
