Aurvista Provides Drill Results on the Porphyry Zone, Douay Property, Quebec-and Plans for 2012 Drilling Program

MONTREAL, QUEBEC--(Marketwire - Sept. 21, 2011) - Aurvista Gold Corp. (TSX VENTURE:AVA) ("Aurvista" or "the Company") is pleased to report the results of the Phase 1 drill program on the "Porphyry Zone", located on its 100% owned (11,440 Ha) Douay property near Matagami, Quebec.

This first phase drill program of 16 holes for 6,329 metres distributed over a strike length of 1.8 kilometres consisted of a general evaluation of the near-surface low-grade gold distribution along the Porphyry Zone. This program tested the extensions on strike and at a maximum depth of 250 m vertical of the Adam 92-7 Zone, the Central Zone and the Exploration Zone located between the two zones which collectively comprise the bulk of the current resources of the zone referred to as the "Porphyry Zone". Gold mineralization was encountered in every hole. Of importance, hole DO-11-33 (previously released by S.E.M.Vior Inc, Feb. 9, 2011) intersected 1.03 g/t Au over 86.6 metres (between 257.4 m and 344.0 m) and hole DO-11-44, located 680 metres to the east, intersected 0.78 g/t Au over 73.5 metres (between 270.0 m and 343.5 m), including 1.03 g/t Au over 46.5 metres.

Assay results for significant intersections are summarized in the table below (intercepts are in meters along the hole):

"We are pleased with the results to-date as they have increased the level of confidence and understanding of the Porphyry Zone. We are now finalizing the integration of the new results in preparation for the next round of drilling on the Porphyry Zone," as well as the other highly prospective zones on the Douay Property" stated the Company's President and CEO, Guy Brunet.

Consultant Work

An external consultant, Mr. Cliff Duke, P.Eng., is currently working on creating a 3-D model of the mineralization at the Porphyry Zone. Variograms and grade block models are also being designed to determine the preferred orientation of the gold mineralization. The outcome of the modelling will be integrated with the geological interpretation to improve the economics of the Porphyry Zone as a low-grade open pit style deposit and to define targets for the follow-up drill program that is slated to begin in the winter 2011-2012.

Drill holes planned for 2012 will focus on extending the known gold resources 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).

Current Resources

The classified resources of the Porphyry Zone (Adam 92-7 and Central) to a maximum depth of approximately 300 m and using a cut-off grade of 0.7 g/t Au are 598,000 tonnes at 1.12 g/t Au (21,000 ounces of gold) in the measured and indicated categories, with an additional 31,727,000 tonnes at 1.10 g/t Au (1,126,000 ounces of gold) in the inferred category. The current classified resources of the Porphyry Zone (Adam 92-7 and Central) are reported in the technical report dated March 15, 2011 (the "Technical Report") prepared for the Company in accordance with NI 43-101 entitled, "Resource Update of the Douay Property and Preliminary Economic Assessment of the Douay West Mineral Deposit, Northern Abitibi, Quebec" and are compliant with standards as outlined in the NI 43-101.

The drilling program on the Douay property is still ongoing 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. Some drilling follow-up was also performed in the extensions of the Zone 10. Most of the results are pending and will be released at the end of each drilling phase.

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 the Company.
