Aurvista Drills High-Grade Intersection (8.4 g/t Gold Over 6.8 m True Width) in the Eastern Extension of the Zone 10 Deposit, Douay Project, Matagami Region, Quebec

Aurvista Gold Corporation (TSX VENTURE: AVA) is pleased to announce the results of a significant gold intercept in a drill hole on its wholly-owned Douay project ("the Property"), located in the Matagami region, Quebec. Drill hole DO-11-61, which was testing the eastern extension on the "Zone 10" gold deposit as part of the "Phase 1" drill program focussed on expanding existing resources on the property, returned a high grade intercept of 8.4 g/t Au over 6.8m true width. The "Zone 10" gold deposit is located 1 km east of the "Central Zone" and 600 m west of the "531 Zone", that host respectively (at a cut-off of 0.7 g/t Au) an Inferred Resource of 6.74 Mt at 0.97 g/t gold (211,000 oz.) and 5.44 Mt at 2.15 g/t gold (376,000 oz) (source.: SGS 43-101 Technical Report for Aurvista, dated March 15, 2011).

The results of the drill hole DO-11-61 intercept are presented in the table below:

Drill Hole #     From        To     Core length      True width        Grade
                  (m)       (m)             (m)             (m)     Au (g/t)
DO-11-61         82.0     110.0            28.0            15.9          4.1
incl.            98.0     110.0            12.0             6.8          8.4
incl.           102.0     107.0             5.0             2.8         14.1

The mineralization at the "Zone 10" deposit occurs at the near-contact between siltstones and basaltic volcanics. A recent interpretation of the "Zone 10" deposit suggests that the mineralized zone is nearly vertical along an east-west-oriented shear zone.

The "Zone 10" deposit currently hosts an Inferred Resource of 1.0 Mt at 2.04 g/t gold (66,000 oz.) with an additional Measured and Indicated Resource of 31,000 t at 2.3 g/t gold (2,000 oz.), at a cut-off of 0.7 g/t gold. The shallow (65 metres vertical) high grade results obtained from hole DO-11-61, drilled 20 metres to the east from the eastern-most previous hole of the "Zone 10" deposit, stand out from historical gold results on this zone in terms of grade and thickness. Moreover, this new drill intercept opens the exploration potential to increase the gold resource towards the east that still remains untested to date over a strike length of 600m and at depth.

Guy Brunet, Aurvista's CEO stated "we are really pleased that these results indicate the prolific ability of the Douay Property to generate additional gold mineralization that could ultimately be either incorporated into a bulk tonnage target or as stand-alone high-grade satellites". The "Phase 1" drilling program on the Douay property was recently completed on selected targets along the contact between volcanic and sedimentary rocks that is believed to be associated with a "pull-apart basin" (the "Pull-apart" Zone) geological setting, where significant historical gold values were intersected. Other follow-up drill holes were also performed in the extensions of the "Zone 10" deposit and the "Central Zone". Results from these holes are still pending and will be released when available. All data are being compiled and the targeting process is well underway for the follow-up drilling phase slated to begin in early January 2012 on the Property. Drill holes planned for 2012 will focus on extending the known gold resources in the bulk tonnage "porphyry " deposits on the Douay Property in both the inferred and indicated categories (currently covering an area of approximately 2 km in strike length) to the west, to the east and to depth (up to depths of 450 m), as well as on extending known resources on other targets on the property, including Zone 10 and other targets and showings on the 12 km NE trending regional "Pull-apart" structure representing the volcanic/sedimentary boundary.

In addition, as described in Aurvista's press release of September 21, 2011, in conjunction with an external consultant, Aurvista is continuing to work on creating a 3-D model of the mineralization at the "Porphyry Zone" (comprising the Adam 92-7 zone and the "Central Zone" described above, and located within 1000 m of "Zone 10"). The outcome of the modelling, including investigation of lower cut-off grades than those used in past resource calculations, will be integrated with the geological interpretation to investigate the potential of the "Porphyry Zone" as a low-grade open pit style deposit, as well as the additional potential of other zones on the property such as "Zone 10".

Aurvista implements an Analytical Quality Assurance Program to control the analytical quality of assays in its exploration work. This program includes the systematic addition of blank samples and certified standards to each batch of samples sent for analysis at commercial laboratories. Blank samples are used to check for possible contamination in laboratories while certified standards determine the analytical accuracy and precision. Samples have been assayed at the Laboratoire Expert Inc. in Rouyn-Noranda and at ALS Chemex Inc. in Val-d'Or. Samples are assayed by fire-assay (30g) followed by atomic absorption according to industry standards. Repeats are completed by fire-assay followed by gravimetry on selected samples.

The technical content of this press release with respect to mineral deposit estimates has been approved by Maxime Dupere, P.Geo., one of the authors of the Technical Report, who is also a "Qualified Person" under NI 43-101 and considered an "Independent Qualified Person". This press release was prepared by Marc L'Heureux, P.Geo., Senior Technical Advisor of Aurvista who acts as the "Qualified Person". He also supervised the exploration program of Aurvista.


Aurvista Gold Corporation is a junior gold exploration and development company. Aurvista's principal asset is the 100% Douay Property, consisting of 218 contiguous claims totalling approximately 11,440 hectares located on the Casa Berardi Fault containing a 43-101 compliant global Resource of 42.6 Mt at 1.29 g/t gold (1.76 M oz.) in the Inferred category and 905,000 t at 1.7 g/t gold (49,000 oz.) in the Measured and Indicated category, at a cut-off of 0.7 g/t gold. In addition to this Resource, the "Douay West" deposit hosts a Measured and Indicated Resource of 313,000 t at 7.75 g/t gold (77,992 oz.) and an Inferred Resource of 267,000 t at 8.53 g/t gold (73,187 oz.), at a cut-off of 4.0 g/t gold.
