Rochester Commences Drift Development And Mobilizes Drill At The
Santa Fe Project, Clavellinos Area
======================================================================

Vancouver, Canada - Rochester Resources Ltd. (TSXV: RCT; OTCBB: RCTFF
and Frankfurt: R5I): Dr. Alfredo Parra, President and CEO, is pleased
to advise that 800 metres of drift development has commenced at the
Clavellinos vein system and the drill rig has been mobilized. A 3000
metre diamond drill program is planned and will commence shortly on the
Clavellinos area of the Santa Fe Project, Nayarit State, Mexico. The
exploration and development program (see Figure 1) will test the
extensive vein systems identified by previous surface sampling and
mapping.

Work to date has defined three main vein systems at Clavellinos, all of
which trend northwest and are sub-parallel with some cross veining.
>From west to east, these are the Jonas Sys�tem, the Clavellinos System
and the Tajitos System. The Jonas system is located 120 metres west of
and parallel to the Clavellinos System, and the Tajitos System is
located 220 metres east of and parallel to the Clavellinos System. The
strike length traced at surface for Clavellinos has increased and is
now greater than 5 kilometres, Jonas has a strike length of 2.7
kilometres and Tajitos has a strike length approximately 1 kilometre.
The strike extensions of all three vein systems are vegetation covered,
and may mask greater strike lengths.

The Company has recently constructed approximately 8 kilometres of new
road access to the central portion of the Clavellinos area. This work
exposed at surface the aforementioned vein systems with a significant
discovery of a 40 metre wide mineralized alteration zone at the
Clavellinos System with three sub-parallel high grade epithermal veins
emplaced within.

Work to date at the Clavellinos area includes trenching, channel
sampling, mapping, structural interpretation, and geological modeling.
Channel and trench samples to date have returned the following results:

WIDTH AVG. GOLD g/t AVG. SILVER g/t ELEVATION

8.80 metres 1.96 140.19 1490 metres
8.32 metres 1.76 115.27 1470 metres
5.58 metres 2.94 271.16 1460 metres
18.40 metres 0.09 80.32 1300 metres

In addition, a significant feature of the vein systems at Clavellinos
is the identification of gold and silver mineralization over a vertical
extent significantly greater than what is found at the Company's
adjacent Mina Real Project. This will be better defined by the phase 1
diamond drill program. The vein structures on the Santa Fe Project
appear similar to those encountered at Mina Real where strong gold and
silver grades have been reported from the Company's mining activities.

Dr. Parra states "This is an exciting time for Rochester as the drill
program will provide an initial test of the extent and strength of the
Santa Fe project and whether the project warrants its own processing
plant. With the operating Mina Real mill nearby we will be able to
quickly capitalize on success in this drill program and move forward
with a separate plant if required"

All assays quoted were carried out by the Durango, Mexico, facility of
SGS Laboratories, a ISO certified and independent laboratory. The
exploration program is under the direction of Hector Chavez, a Mexican
professional geologist who has extensive experience in Mexican
epithermal deposits, and supervised by Dr. Alfredo Parra, who is a QP
as defined in NI 43-101.

About Rochester Resources Ltd.

Rochester represents a pure-play into 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 a 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
(http://www.rochesterresourcesltd.com/s/ShareStructure.asp). We have
identified 36 vein structures
(http://www.ccnmatthews.com/docs/vein_structures.jpg) on our three
projects and embarked on an aggressive exploration program including a
7000m drill program and 2000m drift development program that will
determine the next steps for mine development and production levels.
Rochester is well positioned to advance its projects and can very
quickly become a major player in Mexico. It has a strong senior
management team (http://www.rochesterresourcesltd.com/s/Management.asp)
based in Mexico, the workforce in place to advance its projects, and
the capital to implement the work programs to advance our exploration
and development projects towards production.
