          ROCHESTER TRENCHING DISCOVERS SIGNIFICANT VEIN AT FLORIDA NW


VANCOUVER,  CANADA - ROCHESTER  RESOURCES LTD. (TSXV: RCT; OTCBB: RCTFF AND FSE:
R5I) is pleased to announce the discovery of a new vein called  Florida 4 at the
Florida NW Mina Real  Project in Nayarit,  Mexico.  The Florida 4 vein system is
part of the main fracture system and has similar  mineralogical  characteristics
as the Florida 3 vein system currently being mined at the Mina Real Project. The
Company  anticipates that the Florida 4 vein system will contribute  significant
mill feed to the 50% increase in mill production scheduled for Q3 2008.

Highlight results from the trenching program includes:

o    Trench L1
     Sample #29244 0.5 metres width averaging 24.5 G/T GOLD AND 97 G/T SILVER

o    Trench L1
     Sample #29243 0.8 meters width averaging 7.05 G/T GOLD AND 221 G/T SILVER

o    Trench L4
     Sample #29331 1.2 meters width averaging 7.04 G/T GOLD AND 96 G/T SILVER

o    Trench L5
     Sample #29286 0.6 meters width averaging 6.06 G/T GOLD AND 81 G/T SILVER

o    Trench L10
     Sample #21084 0.7 metres width averaging 1.6 G/T GOLD AND 761 G/T SILVER

** See Table 1 below for full results

At  Florida 4, 11  trenches  have been  developed  exposing  the vein  system at
surface for 2  kilometres.  The  trenches  are located at  different  elevations
ranging from 1000 meters above sea level to 1400 meters above sea level  (figure
1). The vein system has a well defined  quartz  structure with widths on surface
ranging from 0.3 metres to 1.5 metres.  Sampling was  completed at all 11 trench
locations and 9 locations reported significant gold and silver values (Table 1).
Results  collected to date are similar to those received from the Florida 3 vein
system at  similar  elevations.  The  Florida  4 vein  system  is  parallel  and
approximately  450 metres  west from the  Florida 3 vein  system.  Assuming  the
favourable mining horizon of ore ranges from 1350 metres to 900 metres above sea
level as  confirmed  at Florida 3, and an average  vein width  ranging  from 0.5
metres to 1.5 metres over a 2 kilometre  strike  length the company  anticipates
that Florida 4 has the potential to supply significant  additional tonnes of ore
that will help ensure the upgrade in mill  production this summer and contribute
to further mill upgrades in 2009.

The company is currently  developing Florida 4 at different  elevations with the
primary focus being at the 1000 metre elevation.  A drift within waste rock will
be  developed  as an access to the  parallel  veins  located  in this area while
concurrently,  being used as a staging area for diamond  drilling to help locate
parallel  vein  systems  at depth.  A system of ramps  and  raises  will also be
developed for  ventilation  and for efficient  extraction of ore, so the company
can continue increasing production incrementally through 2008 and 2009.

Dr.  Parra  states "The  discovery  and  development  of this new vein system at
Florida NW is a milestone event for Rochester as we believe this will contribute
substantially  to our overall mine life at the Florida Mine and will help ensure
that we will remain on schedule for the production increase this summer."

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 45 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.
