Rochester Acquires a 70% Interest in Second Gold/Silver Property

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 12, 2007) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I) -

The Board of Directors is pleased to announce that it has entered into an agreement to acquire a 70% interest in the Santa Fe gold-silver property located immediately east of its high-grade Mina Real Property in the State of Nayarit, Mexico. The property covers approximately 3800 hectares, and previous work has identified ten zones of epithermal veining and mineralization on the property.

The information available from previous sampling, combined with observations from a recent site visit, suggest there is potential to develop additional ore sources for the nearby Mina Real mill, and to discover additional zones of mineralization. Mineralization occurs over an elevation range of approximately 700 metres, and ranges from high-level discrete veins to broad zones of alteration containing multiple veins. Check sampling by the Company's Mexican consultants is currently underway; based on the results of this work, the Company plans to commence a surface exploration program on the highest priority targets.

The terms of the agreement require that Rochester fund 100% of all costs associated with the exploration and development of the property and pay US10,000/month to the minority owners until the property goes into production. No royalties or other costs are associated with the acquisition.

"We are very fortunate to have been able to acquire such a promising property at this stage in our development," commented Dr. Parra, President and CEO. "We are nearing the completion of our startup phase at our 200 tonnes/day Mina Real Mill and will be working aggressively to meet our next objective of increasing production to 300 tonnes/day from mining activities at Mina Real. In view of the fact that Rochester is now a producing junior, we expect to generate sufficient cash flow from operations to develop this newly acquired property to production status if, as and when justified.

The Santa Fe property is within trucking distance of our Mina Real Mill and has the potential to provide additional mill feed to support a material increase in capacity at the Mina Real Mill or possibly support the development of a second mill in the area."

Dr. Alfredo Parra, the company's President, has an extensive background in mining exploration and operations, including senior management level positions with major Mexican based corporations such as CIA Minera Penoles and Kennecott. Dr. Parra is a QP Member of the Mining and Metallurgical Society of America with special expertise in Mining. Lindsay Bottomer, P.Geo., who is a Qualified Person as defined in NI 43-101, has reviewed the technical content of this news release.

Rochester represents a pure-play into the exploration and development of gold and silver properties located in Mexico. Its key operating personnel are highly skilled and credentialed Mexican citizens with the ability to identify and negotiate the acquisition of other advanced exploration and development properties in the region. Operating management has strong support from an active board of consulting directors with extensive experience in mining, milling and exploration.
