Arian Silver Corporation
(“Arian” or the “Company”) is pleased to announce its initial Canadian National Instrument (NI) 43-101 mineral resource estimate for the San Jose property, located in Zacatecas State, Mexico. The resource estimation has been prepared by independent consultants, A.C.A. Howe International Limited.

This initial resource estimate of 27.7 million ounces (oz) of silver, 64.6 million pounds (lbs) of lead and 147.5 million lbs of zinc, in the inferred mineral resource category, is from 31 holes drilled to an aggregate length of 4,500 metres (m) and is contained within four currently defined resource blocks along 4 km of the strike of the San Jose Vein (SJV). These blocks currently cover an aggregate strike length of some 1,600 m within the 4 km strike length and extend to a depth of 200 m. The percentage of oxide, transitional and primary material is undefined as part of these preliminary “inferred” estimations. The “inferred” resource blocks are summarised in the table below and a plan showing the location of the resources in relation to the strike of the SJV is shown in the following link.

1. Cut-off grade of 0 g/t Ag
2. Ag equals Silver. Pb equals Lead. Zn equals Zinc. 
3. The mineral resource estimates are in accordance with CIM and JORC
   standards
4. The effective date of the mineral resource estimates is 26 February 2008
5. The estimates are based on geostatistical data assessment and 
   preliminary computerised IDW3, Ag grade wireframe restricted, linear 
   block modelling 
Results from a further 34 holes sited within or with close proximity to the zones currently delineated by this estimate are not included in this resource statement as the results were not available for the database modelling cut-off date in mid-December 2007. The results from these holes, together with holes from the on-going Phase-1 drilling, will be reported and modelled for an updated resource statement in due course.

The area covered by this initial resource statement represents only approximately 30% of the known strike length of the SJV within the concessions controlled by Arian. In relation to this section of the strike length, the areas in between the four resource blocks are not yet linked together with sufficient data points to form a minimum compliant (“Inferred”) resource for the enlarged area. However, drilling is currently underway to complete this in-fill linking to expand the current resource along at least a contiguous 4 km strike length within the 12 plus km strike length of the SJV. Arian is scheduling a Phase-2 drill programme to commence very soon to follow on the encouraging results obtained to date. This programme will be designed to both further infill drill areas between the currently defined resource blocks of the SJV and in addition to drill further along strike in both a westerly and easterly direction. Parallel and sub-parallel vein structures mapped using modern-day systematic techniques such as LandSAT Imaging, aerial mapping and geophysics will be also targeted.

Arian’s Chief Executive Officer, Jim Williams, stated, “We are very pleased with these initial compliant resources we have so far estimated at San Jose. These resource estimates are only based on approximately 50% of the drill-holes that we have currently drilled at San Jose and therefore only cover a portion within a strike length along the main SJV of some 4 km (out of 12 plus km). We believe we can expand these resources significantly during 2008.”

Arian Silver Mexico S.A. de C.V., a wholly owned subsidiary of the Company, holds a 100% exclusive option to acquire the San Jose Project. The Project concessions include the past producing San Jose Mine, which was operated by a subsidiary of Penolés from 1973 to 1991 and then by Monarca, which operated the mine between 1993 and 2001. In 2001 the mine closed due to the then prevailing low silver prices.
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 being transported to 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, with check assays regularly conducted by Inspectorate. Each sample has its own unique sample number. Inspectorate’s laboratories in Durango, Mexico and Reno, Nevada are ISO 17025 and ISO 9001:2000 accredited.

Approximately 5% of the analysed samples are re-sampled and sent to the 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.

Inspectorate and ALS Chemex laboratories are independent of Arian.

The samples were analysed for 32 elements by ICP (inductively coupled plasma), proceeded by a three acid digestion. High-grade samples (gold >3 g/t and silver >200g/t) were re-analysed by fire assay with a gravimetric finish.

Howe International Limited, dated April 30, 2007, and entitled “Technical Report on the San José Project, Zacatecas, Mexico”. A copy of this report can be obtained from SEDAR at www.sedar.com

Arian Silver Corporation is a silver exploration 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 mechanized mining techniques over wider mineralized 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.

Forward-Looking Statements

This press release contains certain “forward-looking statements”. All statements, other than statements of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, the mineral resource estimates disclosed in this press release and statements regarding exploration results, potential mineralization, potential mineral resources, future production and the Company’s exploration and development plans and objectives) are forward-looking statements. 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, failure to establish estimated mineral resources, 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. Although the Company believes that the assumptions inherent in the forward-looking statements are reasonable, forward-looking statements are not guarantees of future performance and accordingly undue reliance should not be put on such statements due to the inherent uncertainty therein.

The mineral resource figures disclosed in this press release are estimates and no assurances can be given that the indicated levels of minerals will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While the Company believes that the resource estimates included in this press release are well established, by their nature resource estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. If such estimates are inaccurate or are reduced in the future, this could have a material adverse impact on the Company.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that mineral resources can be upgraded to mineral reserves through continued exploration.
