Azimut Exploration Inc. and Aurizon Mines Ltd. announce that high tungsten grades, up to 4.62% W, have been received for check analyses 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% was obtained compared to previous results. The difference is due to the use of the more accurate X-ray fluorescence method of analysis on samples previously analysed by ICP.
Most of the tungsten-bearing samples (32) were collected along the 6-km long by 50- to 300-m wide Augossan Zone (including the Fluo and Pointe-au-Gossan 1&2 prospects), 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 new tungsten results are as follows:
- All 37 samples returned grades higher than 0.05% W, including 27 with values above 0.1% W.
- The highest values are 4.62% W, 3.08% W, 2.02% W, 1.67% W and 1.01% W.
The check analyses were carried out by X-ray fluorescence on 37 samples with 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 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. All rock samples were assayed by ALS Chemex in Val d'Or, Quebec. A petrographic study is in progress to characterize the mineralized facies.
The Rex South Property comprises 1,822 claims covering 794 km2. The initial 2010 work program led to the discovery of 20 significant mineralized prospects on the property. Azimut was the operator of the program. Azimut's partner Aurizon recently announced its intent to accelerate the 2011 work program with a $4.1 million budget (see press release of January 12, 2011). Emphasis will be placed on initiating widely spaced systematic drilling fences on the Augossan target.
This press release was prepared by Jean-Marc Lulin, P.Geo., acting as Azimut's Qualified Person under NI 43-101. Azimut is a mineral exploration company using cutting-edge targeting methodologies with the objective of discovering major ore deposits. The Company holds the largest mineral exploration portfolio in Quebec, including key gold, uranium and copper properties.
