Behre Dolbear and Company (USA) ("BEHRE DOLBEAR"), an independent mining consulting firm, has recently prepared a new Mineral Resource estimate at the Company's La Negra mine in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM"), CIM Standards. The Estimate is based on 16,422 Diamond drill holes, 22,289 channel samples collected by Minera La Negra S.A. de C.V. (a subsidiary of Aurcana Corp.) during the period 2006 - February 2012, and by Industriales Pe�oles S.A. de C.V. from 1967 to 2000. A summary of the new mineral resource estimate is tabulated below:

Mr Lenic Rodriguez, President & CEO stated: "I am very pleased with the results of the NI 43-101 compliant resource estimate that shows a 50 fold increase from the prior Measured and Indicated resource estimate of 2.3 million ounces of silver to the current estimate of over 115 million ounces of silver, plus significant base metals, which confirms an extended life of mine at La Negra. We have already started the certification of the new discoveries on the North West trend where the silver grades are higher and which we expect to report to the public in the near future. La Negra continues mining primarily from new discoveries".

Notes:
  1. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the estimated Mineral Resources will be converted into Mineral Reserves. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues
  2. The Mineral Resource was estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM"), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standards Committee on Reserve Definitions and adopted by the CIM Council on November 27, 2010.
Qualified Persons & Technical Report

The Mineral Resource estimate announced in this release, has an effective date of August 27, 2012 meets the guidelines as set out in NI 43-101 and was prepared for Aurcana Corporation by Behre Dolbear. The assignment was undertaken by Baltazar Solano-Rico, M.Sc., Geol. Eng. and Mrs. Betty Gibbs, E.M., MSc. both of them qualified persons ("QP") as defined under National Instrument NI 43-101 Standards of Disclosure for Mineral Projects..

Mr. Solano-Rico has consented to applicable disclosure contained herein regarding the Mineral Resource estimate. Mr. Solano-Rico is independent of Aurcana Corporation and its subsidiary companies.

Behre-Dolbear is currently preparing the NI43-101 Technical Report in support of the Mineral Resource estimate. This report will be filed by the company in its entirety on SEDAR (www.sedar.com) within 45 days of the date of this news release.

The Behre Dolbear Mineral Resource estimate reported here is the initial Mineral Resource estimate for the entire La Negra Mine operation. Aurcana has previously commissioned, as recently as Q1, 2010, mineral reserve and resource estimates for individual zones at the La Negra Mine; however, this updated disclosure consolidates and demonstrates the scope and potential that exists for the entire La Negra Mine.

Aurcana's La Negra Mine

The La Negra mine was discovered and developed by Industriales Pe�oles S.A. de C.V. The mine commenced production in 1970 and produced until the mine was put on care and maintenance in 2000. During this period Pe�oles mined approximately 6,600,000 tonnes of ore producing 36 million ounces of silver, 323 million pounds of zinc, 70 million pounds of copper, and 161 million pounds of lead.

In 2006 a joint venture between Aurcana Corporation (80%) and Reyna Mining & Engineering S.A. de C.V. (20%) acquired the property from Pe�oles and placed it into production June, 2007 at a rate of 1,500 tonnes per day. In 2011 Aurcana increased its interest to 99.86%.

La Negra is currently mining, or has defined resources in 13 separate zones that occur along the boundary between a skarn and limestone. The skarn, which varies in width from 10 to 300 metres (m), developed along the contact with a Tertiary diorite intrusion into Upper Jurassic to Lower Cretaceous limestone. Ore minerals in this deposit include sphalerite, galena, chalcopyrite, arsenopyrite, pyrrhotite, pyrite, hessite, and native silver.

The operation at La Negra has expanded significantly since 2007 with the addition of a lead concentrator and increased milling capacity to 2,200 tpd, In Q2, 2012 silver production was 373,037 ounces of silver, a 44.9% increase over Q2 2011

La Negra mine is now milling at a rate greater than 2,200 tpd. The mill upgrade expansion to 2500 tpd is currently in progress and will be completed well before the original expansion date of 2013, with minimal capital expenditures.

The technical information contained in this news release has been reviewed by Nils Von Fersen, P.Geo, the Vice President of Exploration of the Company. Mr. Von Fersen is Qualified Persons ("QP") as defined by National Instrument 43-101 (Standards of Disclosure for Mineral Projects).
