Rochester Continues Profitability From Operations in Third Quarter of Production

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 30, 2008) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I): Rochester Resources Ltd. is pleased to announce financial results for the quarter ended February 29th, 2008. The Company realized net revenue of $2,507,487 on 3,302 ounces of gold equivalent shipped during the three months ended Feb. 29, 2008 (the 2008 third quarter), and generated an operating profit of $213,538 after non-cash charges for depletion and amortization of $248,301. During the 2008 third quarter, head grades averaged approximately 6 g/t gold and 140 g/t silver. Recovery rates for gold surpassed 90 per cent, and silver recovery remained in the 50 per cent range.

"We expect an improvement in net revenues and profitability as we reduce operating costs, improve recovery rates and increase head grades over the coming months. This will all coincide with our increase in throughput production to 300 tpd and implementation of our improved silver recovery circuit planned for the 3rd quarter of calendar 2008." commented Dr. Parra.

The Company recognized net revenue during the nine month period ended February 29th, 2008 of $7,262,014 generated on the sale of 9,693 ounces of gold equivalents, for an average of $749 net revenue per ounce (net of royalty and treatment charges).

Revenues in the 3rd quarter were below plan as a result of several factors, including poor recovery of free gold and silver in the circuit as well as higher dilution during mining. In January when working on alternatives for increasing silver recovery it was found that the amount of free gold and silver in the circuit had increased and was not being recovered during the cyanidation process. By Q3 2008 we will have a gravimetric circuit in place to address this problem and increase silver recoveries up to 70 to 80%. Production from the mine has also been negatively impacted by the failure to achieve targeted development workings. This was caused in part by mine equipment maintenance challenges, specifically the lack of availability of spare parts and qualified mechanics, resulting in overall availability of scoop trams of approximately 30%. The original mine plan called for the mine development to continue in conjunction with production. In order to maintain throughput to the mill with grade control, a minimum of 500 metres of drift development is required each month. If development of 500 metres is not achieved, the consequence is that there are fewer locations from which to produce and less flexibility to maintain optimum grade. With scoop tram availability of approximately 30% actual mine development has been proceeding at a rate of 300 metres per month and consequently the development of an insufficient number of workings from which to mine higher grade ore. During the quarter an order was placed for two new scoop trams and when both are in service availability will increase significantly. The first scoop tram arrived and was placed into service in March with the second due in the next two weeks. Furthermore, the decision has been made to establish a service center in the city of Tepic, located just under two hours from the mine to address spare parts and maintenance issues in a timely manner.

The immediate priority is to carry out sufficient development work to ensure that the ore required to feed the mill at 300 tonnes per day is available with a head grade of 8.5 grams of gold and 150 grams of silver per tonne. Florida NW, where exploration efforts have recently identified seven new veins, will be the focus of development work in the coming months. We are projecting that the plant expansion will be complete and running at 300 tonnes per day in the 3rd quarter of calendar 2008. Once this priority project is completed we plan to resume the exploration programs at Tajos Cuates and Santa Fe.

During the nine months ended February 29, 2008 (the "2008 period") the Company reported an operating profit of $1,045,562 and a net loss of $1.501 million of which $1.4 million was stock based compensation, compared to a net loss of $3,083,491 for the nine months ended February 28, 2007 (the "2007 period"), a decrease in loss of $1,582,491. The periods are not comparable as the Company was not in commercial production prior to June 1, 2007 and had no production in the corresponding 2007 period. As a result, no depletion on mineral property interests or amortization on property, plant and equipment was taken until the 2008 period.

As of Feb. 29, 2008, the company had working capital of $2,215,461. "We are in the position of having a strong balance sheet supported by the ability to generate meaningful cash flow from our mining and milling activities. We expect a substantial increase in sales and revenue once we implement the planned increase to 300 tpd. These revenues will enable us to increase our exploration and development programs, as well as provide adequate working capital for ongoing operations," stated Dr. Parra.

About Rochester Resources Ltd.:

Rochester represents a pure-play in the exploration and development of high-grade gold and silver properties located in Nayarit, Mexico. The Company is a niche player in Mexico which has assembled an attractive portfolio of properties in the Sierra Madre Occidental Range. This is the largest epithermal precious metal region in the world, hosting the majority of Mexico's large tonnage gold and silver deposits. Current production generates growing cash flow and helps fund our ongoing exploration and development with minimum share dilution.

We have identified 37 vein structures on our two Projects (Mina Real and Santa Fe) and recently embarked on an aggressive follow-up exploration program including a 7000m drill program and a 2000m drift development program that will determine the next steps for mine development and production levels. Little follow-up work has been completed to date on the vein structures identified across both Projects.

Rochester is well positioned to advance its Projects and can very quickly become a significant player in Mexico. Rochester has a strong senior management team based in Mexico, a workforce in place to advance its projects through to mine development, and strong financial backing to implement and advance our work programs.
