LONDON, ENGLAND–(Marketwire – June 3, 2011) –Arian Silver Corporation (“Arian” or the “Company”) (TSX VENTURE:AGQ)(AIM:AGQ)(PLUS:AGQ)(FRANKFURT:I3A), a silver exploration, development and production company with a focus on projects in the silver belt of Mexico, today announced a progress update on its San José custom milling operation.

On 31 May 2011, the Company reported a small operating loss for its San José mining and milling operation for the first quarter of 2011. During the period under review several improvements were required as detailed in the 31 May announcement; however, recoveries at the mill were still lower than anticipated. A subsequent investigation revealed the recent theft of approximately eight tonnes of silver-bearing concentrate from the mill and, furthermore, this was not an isolated incident as the ongoing investigation by the Mexican authorities indicates previous thefts occurred during the same quarter.

It is alleged the theft was organised by an individual employed by the plant operator. This individual has been replaced. Security at the mill is the sole responsibility of the mill operator and so are any liability issues. The Company is fully cooperating with the ongoing investigation and several measures to improve security and the overall efficiency of the milling operation are already in place which should mitigate any reoccurrence.

Arian’s Chief Executive Officer, Jim Williams, commented today; “Whilst the discovery of the theft of this concentrate is disappointing news, it does highlight one of the contributing factors to the lower than expected recoveries of silver concentrate during the first quarter reporting period. We were already concerned about inconsistencies between plant and smelter assays which was evidenced during the reconciliation process during this critical start-up period. Now that we have identified and halted this specific security breach and implemented a number of plant improvements we anticipate that our mill recoveries will improve.”
