VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 10, 2007) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I) -

Dr. Alfredo Parra, President, is pleased to announce that Eduardo Luna, Chairman of Silver Wheaton and recently retired President of Goldcorp's Mexican mining operations, has joined the board of Rochester. Mr. Luna has an advanced management degree from the Harvard School of Business and seventeen years experience as President of Luismin, S.A. de C.V., one of Mexico's largest producers of gold and silver and now a wholly owned subsidiary of Goldcorp. He serves on the board of other mining companies such as Genco Resources, is President of the Consulting Board for the School of Mines, Universidad de Guanajuato, and a member of the advisory boards of the School of Mines of both Mexico University and Zacatecas University. Mr. Luna has served as President of the Mexican Chamber of Mines on two occasions and as President of The Silver Institute from 2002-2003. He is also a member of the Board of ICME, the International Council on Metals and the Environment. Mr. Luna replaces Gil Leathley who continues to serve Rochester in a consulting capacity as a member of the mining advisory committee.

"The addition of Eduardo to our board is further evidence of our commitment to Mexico and our desire to build a strong Mexican based mining company," commented Dr. Parra. "Rochester represents a pure-play into the exploration and development of gold and silver properties located in Mexico. With the commissioning of the Mina Real mill underway, I believe that our Mina Real and Santa Fe properties have the potential to produce a sustained level of gold and silver production to support our growth objectives."
