Arian Silver Corporation (“Arian” or the “Company”) is pleased to announce an update on the diamond drilling programme which commenced in May 2007 at the San Jose Project, Zacatecas state, Mexico.

The drilling has identified a wide, lower grade, near-surface mineralised zone, which may be amenable to open-pit mining. This near-surface oxide mineralization is entirely separate and not to be confused with the San Jose main vein.

Drill-holes 004 to 007 were drilled in an area east of the main head-frame in an area referred to as “Block 450”. Underground mapping and archive data has identified a number of historic blocks that have not previously been mined. Drilling in this area to confirm historical data has identified higher grade silver veins (with base-metal content) which are within a much wider lower-grade disseminated zone of silver mineralisation. This lower-grade disseminated zone of mineralisation is located near surface and may be amenable to open-pit mining. The grades are comparable to similar oxide open-pit mines, for example, Rochester in Nevada, where Coeur d’Alene Mines excavate material grading 28 g/t silver and 0.34 g/t gold.

Arian’s Chief Executive Officer, Jim Williams, said, “This near surface oxidised mineralisation identified in “Block 450” may have the potential for open-pit mining. This area could be put into production very quickly, subject to our ongoing scoping studies, and help us reach one of our main objectives, to be in production by 2009.”

The assay data from these holes is summarized in the table below:-

The Company has made considerable progress on its early stages of drilling at San Jose. To date the Company has completed twenty-six ‘NQ’-size diamond drill holes totalling some 4,000 metres (m) of the 5,000m phase 1 programme.

In view of these results, Arian has decided to expand the phase 1 program to 7,000 metres.

The ongoing drill programme has been designed both to confirm the historical drill-hole data and to expand on a number of priority target areas. Further assays are in the lab and are due shortly from the San Jose main vein.

All technical information for the San Jose Project is obtained and reported under a formal quality assurance and quality control (QA/QC) programme. The core is logged and photographed by Arian staff and then split using a diamond saw. Half the core is stored on-site in a secure core shed and the other half is sampled, bagged and secured before transporting to the Inspectorate’s sample preparation facility in Durango, Mexico. The entire half-core is crushed and two kilograms is pulverized and homogenized. 150 gram pulp samples are then air freighted to Inspectorate’s analytical laboratory in Reno, Nevada for analysis. Systematic assaying of duplicates is performed for precision and accuracy; check assays are regularly conducted by Inspectorate. Each sample has its own unique sample number. The Inspectorate’s laboratories in Mexico are ISO 17025 and ISO 9001:2000 accredited.

Approximately 5% of the analysed samples are re-sampled and sent to ALS Chemex preparation facility in Guadalajara, Mexico. The samples consist of both coarse reject samples and 150 gram pulp samples. The coarse material is crushed and pulverised, and all the pulp samples are air freighted to ALS Chemex’s analytical laboratories in Vancouver, British Columbia, for analysis. Results from all duplicate analyses are compared to identify potential analytical or sampling errors.

The Inspectorate and ALS Chemex laboratories are independent of Arian.

The samples were analysed for 32 elements by ICP (inductively coupled plasma), preceded by an Aqua Regia digestion. High-grade samples (gold >3 g/t and silver >100g/t) were re-analysed by fire assay with a gravimetric finish.

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 mineralised structures, which reduces the overall operating cost per ounce of silver, and to build up 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. Arian is supported by the Dragon Group in London, and the Endeavour Group in Canada.
