Aurvista's Step-Out Drilling Demonstrates Expanded Potential on the Porphyry Zone Deposit of the Douay Property, in the Northern Abitibi Region of Quebec

MONTREAL, QUEBEC--(Marketwire - Dec. 21, 2011) - Aurvista Gold Corp. (TSX VENTURE:AVA) is pleased to announce the results of a step-out drill hole intercept on its wholly-owned Douay project ("the Property"), located in the Matagami region, Quebec. Drill hole DO-11-70, which was testing the extension 200 meters to the East on the "Porphyry Zone" gold deposit as part of the "Phase 1" drill program focussed on expanding existing resources on the property, returned a significant gold intercept of 57.0 m at 1.42 g/t Au, including 7.5 m at 6.07 g/t Au (in true width drilled perpendicular to the mineralized zone). The "Porphyry Zone" gold deposit is located along a strike of 2 kilometres and is comprised of the "Adam 92-7" and the "Central" zones, that host together (at a cut-off of 0.7 g/t Au) an Inferred Resource of 31.7 Mt at 1.1 g/t gold (1.1 M oz. of gold) (source: SGS 43-101 Technical Report for Aurvista, dated March 15, 2011).

The results of the drill hole DO-11-70 intercept are presented in the table below:

Drill Hole # From
(m)
To
(m)
True width
(m)
Grade
Au (g/t)
DO-11-70 192.0 249.0 57.0 1.42
incl. 217.5 225.0 7.5 4.77
incl. 217.5 222.0 4.5 6.07

Hole DO-11-70 stepped-out 200 meters to the east of the "Central Zone", demonstrates significantly the expanded potential of the "Porphyry Zone". Furthermore, its eastern extension still remains untested over a strike exceeding 1 kilometre and at depth. The mineralization encountered in hole DO-11-70 is characterized by disseminated pyrite within a silicified, hematized and sericitized porphyritic syenite as generally observed throughout the "Porphyry Zone".

Regarding the "Porphyry Zone", Aurvista is working on creating a 3-D model of the mineralization comprising the "Adam 92-7" Zone and the "Central Zone" described above. 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" and "Zone 531".

As mentioned in the Company's press release of November 8, 2011, 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. Historical and current 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.

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", and also supervised the exploration program of the Company to date.

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.
