Thursday, April 26, 2012

Aurizon Mines Ltd.: New Results at Marban Highlight Potential to Define High Grade Ore Shoots07:30 EDT Thursday, April 26, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 26, 2012) - Aurizon Mines Ltd. (TSX:ARZ)(NYSE Amex:AZK) is pleased to release new drill results from the Phase Two program conducted under the terms of the Aurizon Mines Ltd. ("Aurizon") earn-in option on the Marban property, located in the Malartic gold camp, Abitibi region of Quebec. Results from 22 new drill holes and six (6) extensions of previous holes completed on the Marban gold deposit are included in this release. Drill results are tabled on the following pages. The new results highlight the potential to define high grade shoots within the Marban deposit, which include:Hole MB-07-024 ext, drilled on section 4300E, was extended to investigate the Eastern Down Dip Zone and returned 196.5 grams of gold per tonne over 1.2 metres at a vertical depth of 415 metres Shallow in-fill drilling between sections 4300E and 4400E returned the following high grade intersections: 20.5 grams of gold per tonne over 2.0 metres at a vertical depth of 180 metres (MB-11-248) 36.7 grams of gold per tonne over 1.1 metres at a vertical depth of 155 metres (MB-07-019ext) 29.8 grams of gold per tonne over 1.0 metre at a vertical depth of 65 metres (MB-12-252) Hole MB-12-295 drilled on section 3,575E and part of the in-fill drilling on the near surface Western High Grade Zone intersected 51.4 grams of gold per tonne over 1.1 metres at a vertical depth of 95 metres The new results show positive intercepts over a strike length of 1,050 metres on the deposit (from section 3550 to 4600) and from surface to a vertical depth of 500 metres. The deposit is developed inside a 200 to 500 metres wide deformation system controlled by a kilometric drag fold along the Marbenite shear zone. Mineralization is in the form of multiple lenses, each one having a thickness that varies between 5 to 80 metres. Mineralization is characterized by chlorite - carbonate - albite alteration associated with a variable amount of quartz veining and iron sulphides. The Phase Two program will include 34,000 metres of diamond drilling, an updated mineral resource estimate and basic technical studies, including metallurgical testwork. Drilling commenced on December 13, 2011, and four drill rigs are currently in operation. Two are testing the extension at depth of the Marban deposit, one is following up on the fences drilled during first phase between the Norlartic and Marban deposits, and the fourth drill is investigating select exploration targets outlined on the Marban property. To date, 75 holes and nine (9) extensions of previous holes have been completed for a total of 26,380 metres. The Phase Two program and updated resource estimate are expected to be completed by the end of the second quarter of 2012. Marban deposit drilling The 2011 Phase One drill program demonstrated the continuity of the mineralisation between surface and a vertical depth of 250 metres, as well as the grade consistency, and led to the discovery of the Western High Grade Zone. This first phase also identified the Eastern Down Dip Extension Zone, which is located below a vertical depth of 250 metres and remains open at depth and laterally. The objectives of the Phase Two drilling program are:Improve the quality of the Marban near surface resources The objective is to improve the quality of the known resources and to increase the potential to find more mineralised corridors within a pit shell to help decrease the stripping ratio, and will include drilling the Western High Grade Zone. Develop a mineral inventory below a vertical depth of 250 metres: This objective targets the identification of new gold resources inside the Marban structural zone. Preliminary interpolation on the Eastern Down Dip Zone indicates a strong potential to identify gold resources between a vertical depth of 350 and 600 metres. The mineralised structure is considered open laterally and downdip. New holes and the extension of previous holes are planned at vertical depths of 300 metres to 1,000 metres to test the consistency and extension of the Eastern Down Dip Zone at an average drill hole spacing of 50 metres. Aurizon Option Aurizon can earn up to a 65% interest the Marban property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold Mining Corporation ("NioGold") and Aurizon. The initial 50% interest can be earned by incurring expenditures of $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 remains the project operator during the initial earn-in period. The Phase One program commenced on August 30, 2010, and was completed on August 9, 2011. The program consisted of 50,253 metres of diamond drilling (170 holes, 8 extensions) at a total cost of $6 million. Drilling was distributed between the Marban (41,270m) and Norlartic (4,319m) deposits and exploration drill hole fences between the two deposits (4,664m). Highlights include the identification of two new gold zones surrounding the former Marban mine named the High Grade Western Zone and Eastern Down Dip Zone.

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 is conducted under the supervision of Yan Ducharme, M.Sc., P.Geo. (OGQ), NioGold's Exploration Manager and a Qualified Person as defined by National Instrument 43-101. This news release was prepared under the supervision of Martin Demers, P.Geo., General Manager, Exploration 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 information There is one sketch attached to this news release showing the Marban deposit drill hole locations and the longitudinal figures.
