News Release Issue No.  4  - 2011

VANCOUVER, Feb. 15 /CNW/ - Aurizon Mines Ltd. ("Aurizon") (TSX: ARZ) (NYSE: AZK) is pleased to announce that high tungsten grades of up to 4.62% have been received from check analysis performed on 37 tungsten-bearing grab samples collected during the 2010 field program on the Rex South property, Nunavik, Quebec. An average grade increase of 130% for tungsten was obtained due to the use of the more accurate X-Ray fluorescence method of analysis. (see below for more details).

Thirty-two (32) of the thirty-seven (37) tungsten-bearing samples were collected along the 6 kilometre long by 50 to 300 metre wide Augossan Zone (including the Fluo and Pointe-au-Gossan 1 & 2 areas) (see attached map), which is open in all directions, and where significant results for copper (up to 2.56% Cu), gold (up to 23.3 g/t Au) and silver (up to 90.0 g/t Ag) have been obtained (see press release of November 8, 2010). The Augossan Zone appears as a very attractive exploration target for a large deposit in terms of metal content. The polymetallic and disseminated nature of the mineralization, as well as dense veining, and its association with a fluor-rich intrusion show similarities with porphyry type mineralized systems.

The check analyses were carried out by X-ray fluorescence on 37 grab samples with tungsten ("W") grades higher than 0.05% W and resulted in an average grade increase of 130% compared to grades previously obtained for the same samples using an ICP method. The new results are as follows:

  • All 37 samples returned tungsten grades higher than 0.05% W, including 27 with values above 0.1% W.
  • The highest tungsten values are 4.62% W, 3.08% W, 2.02% W, 1.67% W and 1.01% W.

The differences between the two analytical methods are attributed to the incomplete dissolution of tungsten-bearing minerals during multi-acid extraction prior to ICP analysis. The X-ray fluorescence method is considered to be significantly more accurate for tungsten analysis.

Property Summary and Outlook

Aurizon may earn up to a 65% interest from Azimut Exploration Inc. ("Azimut") in the Rex South Property comprising 1,822 claims covering 794 square kilometres. The initial 2010 work program led to the discovery of 20 significant mineralized prospects on the property. Azimut was the operator of the program. Aurizon recently announced its plans to accelerate the 2011 work program with a $4.1 million budget (see press release of January 12, 2011).  The detailed planning of the next exploration program is underway.  Emphasis will be placed on initiating widely spaced systematic drilling fences on the Augossan target.

Quality Control

Rock samples were assayed by ALS Chemex in Val-d'Or, Quebec, using fire assay for gold, ICP method for all other elements and X-ray fluorescence method for tungsten.  All rock samples were assayed by ALS Chemex in Val d'Or, Quebec.  A petrographic study is in progress to characterize the mineralized facies.

This press release was prepared under the supervision of Martin Demers, P. Geo, Manager, Exploration, a Qualified Person as defined by National Instrument 43-101, who has also verified the data disclosed, including sampling, analytical and test data.
