The main mineralized zone, which occurs in an area of significant outcrop exposure, has been recognized over a strike length of 3.3 kilometres and a width of 50 to 200 metres, and is open in all directions. This zone, named the Augossan Zone, was identified during an initial exploration program conducted on the property this summer. The program was funded by Aurizon under the terms of an option agreement with Azimut Exploration Inc. (“Azimut”) announced on
- Aurizon considers the Augossan Zone to be a very attractive exploration target. An initial drilling program is planned for 2011. - The Augossan Zone and several other significant prospects represent porphyry-type mineralization. This type of deposit is of considerable economic importance worldwide and includes many examples of world-class mines. Field observations at Rex South this summer indicate a very large exploration target, corresponding to a typical target size for this deposit type. - The identification of porphyry-type mineralization is considered to be an exploration breakthrough for this large region of Northern Quebec.
Summary of results (see attached map: http://files.newswire.ca/734/SketchNR.pdf)
The results for 1,079 rock grab samples out of a total of 1,162 have been received and are reported below. The results take into account all the analyzed samples, including those from unmineralized or poorly mineralized areas. The same results are subdivided by prospect in the appendix. It should be noted that grab samples are selective by nature and unlikely to represent average grades on the property.
- Gold: 134 samples returned grades higher than 0.1 g/t Au, including 30 samples with grades ranging from 1.0 g/t to 23.3 g/t Au - Silver: 151 samples returned grades higher than 1.0 g/t Ag, including 39 samples with grades ranging from 10.0 g/t to 124.0 g/t Ag - Copper: 125 samples returned grades higher than 0.1 % Cu, including 37 samples with grades ranging from 0.5% to 8.25% Cu - Tungsten: 34 samples returned grades higher than 0.05 % W, including 24 samples with grades ranging from 0.1% to 0.99% W. This is the first time significant grades of tungsten have been found in Nunavik. Several areas also returned significant values for the following commodities: - Bismuth: 39 samples with values ranging from 0.01% to 0.19% Bi - Molybdenum: 30 samples with values ranging from 0.01% to 0.35% Mo - Rubidium: 61 samples with values ranging from 0.05% to 0.18% Rb
Property Summary and Outlook
The Rex South property is located approximately 145 kilometres southeast of the
Rex South is located in the Archean Minto Subprovince. The mineralized areas on the property – the Augossan Zone, the Fluo Zone, and the Le Breuil-N, Larissa and Kumo prospects – are considered porphyry-type targets associated with granitic intrusions, dykes and their surrounding host rocks. Other target types considered for the property are sediment-hosted gold-copper and volcanogenic massive sulphides.
Results of a property-scale airborne geophysical survey and a detailed lake-bottom sediment geochemical survey are pending. Azimut and Aurizon will design a comprehensive follow-up exploration program when all pending results are received and interpreted.

APPENDIX Results according to prospect - Rex South Property, Nunavik, Quebec To date, at least 29 prospects have been discovered on the Rex South property, including 8 previously reported historical occurrences (see Azimut press releases dated May 18, 2010 and December 4, 2009). At the scale of the property, 18 of these prospects define three (3) different mineralized trends as follows: 1) The Augossan Trend is a 12-kilometres trend striking NW-SE with the following main areas: Augossan Zone (138 rock samples, including those from unmineralized sites) - Gold: 0.1 to 23.3 g/t Au (39 samples) - Silver: 1.0 to 90.0 g/t Ag (77 samples) - Copper: 0.1 to 2.56% Cu (52 samples) - Tungsten: 0.05 to 0.93% W (20 samples) - Rubidium: 0.05 to 0.18% Rb (40 samples) - Several samples also returned bismuth values up to 0.13% Bi and molybdenum up to 0.11% Mo - A consistent envelope of mineralization was outlined with a minimum strike length of 3.3 kilometres and widths ranging from 50 to 200 metres; this envelope includes the historical Pointe-au-Gossan 1 & 2 prospects - Historical best grades were 47.2 g/t Au and 50 g/t Ag (Pointe-au-Gossan 1), and 27.4 g/t Au, 31.5 g/t Ag and 5.1% Cu (Pointe-au-Gossan 2) - Mineralization is in the form of disseminations and veinlets of pyrrhotite, chalcopyrite, pyrite, magnetite, local native copper, fluorite, molybdenite and arsenopyrite, hosted by sheared mafic metavolcanics, biotitic gneiss and aplitic/pegmatitic/granitic dykes - Alteration is dominated by silicification, biotite, garnet, chlorite and locally cordierite. Fluo Zone (157 rock samples, including those from unmineralized sites) - Located 1.5 kilometres northwest and along strike from the Augossan Zone - 1.6 x 0.5 kilometre area of discontinuous but often mineralized outcrops - Gold: 0.1 to 4.26 g/t Au (15 samples) - Copper: 0.1 to 0.29% Cu (9 samples) - Tungsten: 0.05 to 0.99% W (9 samples) - Rubidium: 0.05 to 0.09% Rb (18 samples) - Several samples also returned bismuth values up to 0.19% Bi, molybdenum up to 0.36% Mo, and tellurium up to 61 g/t Te - Mineralization is in the form of pyrite and chalcopyrite disseminations and veinlets, quartz and magnetite veinlets, and disseminated molybdenite hosted by porphyritic fluorite-bearing granite.
