Infill Drilling Confirms Continuity of the High Grade Mineralization of the 123 Zone at the Casa Berardi Mine

Aurizon Mines Ltd. (TSX: ARZ; NYSE Amex: AZK) is pleased to report further results from infill drilling of the 123 Zone from the exploration drift on the 810 metre level at its Casa Berardi Mine in north-western Quebec.
Part of the current exploration program is focused on the upper and depth extensions of the 123 Zone, located approximately 1.0 kilometre east of the West Mine shaft, with the objective of extending the known mineralization.
Underground drilling has completed a further six new holes on a 50 metre spacing. The program is targeting a series of previously outlined stacked mineralized lenses within a south-east dipping host corridor, 200 metres thick by 1,000 metres of vertical strike. The thickness of the individual lenses within the corridor is in the range of 3 to 35 metres.
Four out of six drill holes returned mineralized values having a metal factor above 10 (true width in metres x the gold grade in grams per tonne), or higher. A table of all the drill hole results are included in this release and are illustrated on the attached sketch. The six drill holes cover an area of approximately 200 metres along strike to a depth of 200 metres below the 810 metre level.
The best results were 10.0 grams of gold per tonne over 35.1 metres (true thickness) in hole CBP-0194 and 9.1 grams of gold per tonne over 27.3 metres (true thickness) in hole CBP-0193, and were intersected approximately 50 metres and 100 metres, respectively, from the previously reported 42.1 grams of gold per tonne over 21.5 metres (true thickness) in hole CBP-0160 (see Aurizon news release dated August 30th 2010). These results indicate that there is a high grade core within the 123 Zone, extending over a strike distance in the order of 200 metres vertically by 50 metres horizontally and having an approximate thickness of 25 metres. The deepest hole to date in the 123 Zone is CBP-0115 (see Aurizon news release dated February 11th 2010) at 1,100 metres which intersected two structures: 5.5 grams of gold per tonne over 10 metres (true thickness) and 20.7 grams of gold per tonne over 0.7 metres (true thickness).
As at December 31, 2009, the 123 Zone contained inferred mineral resources of 714,000 tonnes at a grade of 9.4 grams of gold per tonne, or 216,000 ounces.
In the 123 Zone, gold mineralization occurs in quartz veins, cherty units and massive sulphide structures located between the South 123 Zone break to the east and the South break to the west in a volcanic bearing environment. This corridor extends for more than 1.0 kilometre vertically, containing distinct stacked lenses.
"The continuity in thickness and grade of the mineralized system in the 123 Zone confirms the potential to extend the mineralization at depth and to find more mineralization along strike of this structure" said Gilles Carrier P. Eng., Principal Exploration Geologist.
Outlook
Underground drilling will continue with two rigs from the 810 metre exploration drift to define the down dip extension of the zone. The 123 Zone remains open to depth and along strike to the east, however step out drilling is limited due to the orientation of the mineralization relative to the drill bases at the 810 metre exploration drift. The two drill rigs will primarily perform infill drilling of the 123 Zone in order to upgrade the resources identified in the campaign. A drill rig has recently started at the 550 metre track drift to verify the upper extension of the zone. An updated mineral resource estimate is expected to be completed by year-end.
As previously reported, $2.8 million will be invested in the second half of 2010 to commence a ramp from the 810 metre level down to approximately the 1,000 metre level which will provide drill bases to test the depth extensions of both the 123 and 118 Zones as well as commence mine development of these zones.
