Rochester Resources Ltd.: Mina Real Production Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 8, 2007) - Rochester Resources Ltd. (TSX VENTURE:RCT)(OTCBB:RCTFF)(FRANKFURT:R5I) -

"The Mina Real plant has been operational for 11 days since resumption of milling operations and is performing satisfactorily," stated Dr. Alfredo Parra, President. "In spite of the global challenges involved in assembling equipment, materials and competent skilled labour, the Mina Real mill was put into production after only twelve months from receipt of permits." An update follows:

Mill

Operating results during the March 2007 period of the test-production phase indicated that it would be prudent to modify the grinding circuit to obtain throughput of about 250 tonnes per day and the gold/silver final recovery section to ensure planned recovery. Accordingly, the following major modifications planned for late 2007 have been brought forward:

- Installation of larger capacity solution pumps and a third grinding mill; and

- The installation of a cyanide destruction circuit to treat mill effluent.

These tasks were completed during the recent mill shutdown. In addition, the project construction management team was replaced by experienced operational supervisors. Locally-recruited mill operating staff was trained in emergency procedures, operational and maintenance skills. A preventive maintenance system is in the process of being developed and training in maintenance procedures is well advanced. Further improvements in plant productivity will take place when the third mill is put into operation mid-month. Regular weekly shipments of gold and silver precipitate to the refinery have recommenced.

"I am impressed with the design and standard of construction that has combined to create a very sensible operational plant," commented Gil Leathley, Director, following a site visit to the plant earlier this week. Mr. Leathley is a retired Chief Operating Officer of a major US based international mining company and has extensive knowledge of the operation and construction of various sized milling plants.

Florida Mine

Mining activity has been ongoing over the past twelve months and it is estimated that over 20,000 tonnes of ore, with an average grade of approximately 9 grams/tonne of gold and 180 grams/tonne of silver, is currently stockpiled, and available for milling.

Independent assay results from channel samples taken over 80 metres of development mining recently completed in Level 1240 of the Florida 3 vein, produced an average grade of about 12 grams/tonne of gold, 200 grams/tonne of silver and an average width of about 1.2 metres. Level 1240 is in the upper portion of one of the three vertical vein structures currently being mined at the Mina Real gold/silver property in Nayarit, Mexico. These grades are significant when combined with the high grades reported over 775 metres of development mining in lower levels of Florida 3 and the significantly higher grades reported in ramping down to the 1090 metre elevation.

In addition, the Level 1160 drift has been advanced approximately 350 metres through the intrusion into the area on the other side and is close to the projected intersection point of the vein structures discovered by surface trenching to the NW of the intrusion.

Dr. Parra is currently the Company's in-house Qualified Person and QP Member of the Mining and Metallurgical Society of America with special expertise in Mining.

Corporate Appointments

Dr. Parra is also pleased to announce the appointment of Nick DeMare, CA as Chairman and a member of the board of directors of Rochester. Nick is a founding shareholder of Mina Real and has been active as a director and officer of a number of resource companies. Earlier in his career Nick was employed as a General Practice Manager with Coopers and Lybrand Chartered Accountants with specialization in the resource sector. He has operated extensively in Latin American countries and is conversant in Spanish.

In addition, Jose Manual Silva, CPA and Director of Finance of Rochester's Mexican subsidiary since January 2007, has been appointed Chief Financial Officer of Rochester. Jose has a strong background in accounting and taxation in Mexico. He was a Controller with Luismin S.A. from 1979 to 1988 and has held positions of Internal Audit and Budget Manager and Controller with two other Mexican based mining companies from 1988 to 1997. Since 1997 he has been a consultant who has provided accounting services to Canadian public companies operating in Mexico. In recognition of his increased responsibilities, Mr. Silva has been granted an additional 100,000 stock options at $1.65 per share. The options vest over their term of three years.

Douglas F. Good, former Chairman and Chief Financial Officer, will remain a Director and continue to concentrate on the area of Corporate Development on a part-time basis. "I am extremely pleased with the corporate changes that Dr. Parra has made," commented Mr. Good. "I believe that Rochester is now well on its way to becoming a recognized and profitable junior Mexican gold/silver producer. In addition to strengthening the corporate structure, these changes will allow me to devote more time to family and my increasing responsibilities as a Director and CFO of ComWest Enterprise Corp. (TSX VENTURE:CWP)."

Rochester represents a pure-play into the exploration and development of gold and silver properties located in Mexico. With grades reported in 2007 from mine development activities ranging all the way from an average of 12 grams/tonne of gold and 200 grams/tonne of silver over 775 metres of drift development, to 30.8 grams/tonne of gold and 212 grams/tonne of silver over eleven continuous samples taken from approximately 20 metres of ramp development within the vein system, the Mina Real Mine could certainly be considered a "high-grade" gold/silver deposit.

ON BEHALF OF THE BOARD
