Fresnillo Plc Comments on Arbitration Decision

Fresnillo plc today announced that an Arbitration Panel formed according to the Arbitration Rules of the International Chamber of Commerce has delivered its decision in respect of claims made by Vancouver-based MAG Silver Corp  (TSX: MAG and NYSE:MVG), Fresnillo's joint venture partner in the advanced exploration stage Juanicipio silver project in Mexico.

The Arbitration Panel rejected MAG's claims that Fresnillo was deficient in the execution pace or performance of drilling at the project. The Arbitration Panel denied both of MAG's principal demands, specifically: (a) that Fresnillo be ordered to pay damages to MAG of up to US$61 million related to MAG's claims that delays by Fresnillo delayed the start of production; and (b) that Fresnillo be ordered to sell or transfer its equity participation in the Minera Juanicipio joint venture to MAG.

The Arbitration Panel upheld certain other MAG claims, including claims related to Fresnillo's announcement in December 2008 that it intended to make an unsolicited bid to acquire MAG.  Fresnillo announced its intention based on the opinion of external legal counsel regarding a certain clause in the JV Agreement. The Arbitration Panel, based on a different interpretation of that clause, ordered Fresnillo to reimburse MAG for legal fees of US$1.86 million incurred by MAG in connection with the announcement of Fresnillo's intended offer.

The cost of the arbitration was US$775,000. The Arbitration Panel ruled that each party should pay 50% of the arbitration cost and bear its own legal costs.

Jaime Lomelin, Chief Executive Officer, said, "We are pleased that the Arbitration Panel has dismissed MAG's most serious claims. We continue to believe Fresnillo has acted appropriately and in accordance with the terms of the joint venture agreement."
