Acquisition of Additional Concession Areas at San Jose

September 5th, 2007

Arian Silver Corporation (“Arian” or the “Company”) is pleased to announce that it has increased its licence ownership around its San Jose property by over 50%.

The Company has acquired 10 mining concessions that have added an additional 2,313 hectares (ha) to bring Arian’s total licence holdings at San Jose to 6,353 ha. With the addition of these newly acquired mining concessions, Arian now controls some 12.5 km of the projected strike length of the San Jose vein system. A map showing the location of these newly acquired concessions is shown in the link below: -

The new concessions are located between the Company’s San Jose property and Grupo Mexico’s ‘La Tesorera 3’ concession to the north and are immediately adjacent to Peñoles ‘La Tesorera’ property. The location of the new concessions is of particular significance as it covers the contact zone between the Tertiary-aged ‘La Blanca’ Granodiorites and Jurassic-aged Limestones, where recent drilling by Peñoles has intersected massive sulphide mineralization within limestone units within its La Tesorera property. In addition, the new concessions contain a number of old mine shafts and prospects that explored both the San Jose vein system as well as a number of other parallel and sub-parallel veins and other areas of non-vein-type mineralization.

Five of the new concessions were purchased from existing holders for a total consideration of US$115,000 and have an underlying 2% Net Smelter Return (NSR). The other five concessions were staked on open ground and have no underlying NSR.

Arian’s CEO, Jim Williams, commented, “With the addition of these newly acquired mining concessions, we have a number of additional exploration targets with excellent upside potential. Detailed geological mapping and sampling of these new areas is already underway.”

Arian Silver Corporation is a silver exploration and development company listed on London’s AIM and “PLUS”, on Toronto’s TSX Venture Exchange and on the Frankfurt Stock Exchange. Arian is active in Mexico, the world’s largest silver producing country. The Company’s main projects are the Calicanto and San Jose projects in Zacatecas state, and the Tepal project in Michoacán State. Part of Arian’s forward-looking strategy lies in the envisaged use of large scale mechanised mining techniques over wider mineralized structures, which reduces the overall operating cost per ounce of silver, and to build up Canadian National Instrument 43-101 compliant resources.

Arian was founded by Jim Williams, Chief Executive Officer, and Tony Williams, Chairman, who together have over 50 years experience in exploration, project construction and mining worldwide.

These forward-looking statements reflect the current expectations or beliefs of the Company based on information currently available to the Company. Forward-looking statements are subject to a number of risks and uncertainties that may cause the actual results of the Company to differ materially from those discussed in the forward-looking statements, and even if such actual results are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on the Company. Factors that could cause actual results or events to differ materially from current expectations include, among other things, the possibility that future exploration results will not be consistent with the Company’s expectations, uncertainties relating to the availability and costs of financing needed in the future, changes in commodity prices, changes in equity markets, political developments in Mexico, changes to regulations affecting the Company’s activities, foreign currency fluctuations, delays in obtaining or failures to obtain required regulatory approvals, the uncertainties involved in interpreting exploration results and other geological data, and the other risks involved in the mineral exploration and development industry. Any forward-looking statement speaks only as of the date on which it is made and, except as may be required by applicable securities laws, the Company disclaims any intent or obligation to update any forward-looking statement, whether as a result of new information, future events or results or otherwise.
