<p align="justify">"These reconnaissance exploration samples confirm the
Silveria property encompasses rich mineralization," stated A. Paul Gill,
President & CEO, “We look forward to receiving a full 43-101 report on
this project and continuing forward with the development of the
project."</p>
<p align="justify">Pete Ellsworth, consulting geologist to the Grenville
Gold Silveria Project, examined 44 principal portals at the Pacococha,
Millotingo, and Germania mining districts to observe vein outcrop and
survey the portal locations. In addition, 34 mine dump grab samples were
collected and analyzed at ALS Chemex Lima laboratory for gold plus 35
element ICP scan to characterize the geochemistry and zonation of the
district. Results show anomalous to low grade gold values in most
samples plus gold ore grades in the Millotingo, Belgica, Reserva and
Ernesto Segundo veins.</p>
<p align="justify">Silver values show mineralization from all samples
collected, with assays ranging from 3.5 to 2,220 grams per ton and base
metal credits range up to 3.9% Copper, 7.2% lead, and 19.7% zinc. This
confirms the high grade polymetallic nature of the veins from all the
districts. Basic statistics of the 34 samples show the following
results:</p>

<p align="justify">The geochemical results from the sampling program
confirm Grenville’s assumption that these veins are epithermal and the
upper levels of the system are eroded over the Pacococha veins.
Structural geologic interpretations combined with the geochemical
studies suggest the Millotingo mine is stratigraphically higher in the
epithermal system where precious metals are enriched and base metals
depleted. The boiling level therefore must daylight between the
Millotingo zone and the Pacococha mines. These epithermal deposit model
interpretations will guide a regional exploration program to locate
additional veins and disseminated mineralization.</p>
<p align="justify">As stated in a release dated May 8, 2007, the company
is also making immediate preparations to begin a test heap leaching
program of the Millotingo tailings dam. Initial estimates of tailing
grades reveal between 85 grams (3 ozs) and 567 grams (20 ozs) per metric
ton of silver, and between 1 and 3 grams per metric ton of gold. The
company will proceed with a bulk sample program in order to test the
potential for the project to yield significant positive cash flows.</p>
<p align="justify">The Silveria project property was in production up
until 1991, but has not received serious attention until now. Published
documentation on historical production, reserves, reserve ore grades and
estimated mine life at December 1990 on the Millotingo and Pacococha
Mine are available through “The Peru Report’s Guide to Mines and Miners
in Peru – Las Minas Del Peru", 1992, page 197-199, 223-225, researched
and edited by Jonathon Cavanagh, (Published by Peru Reporting Servicios
Editoriales S.R.L.) </p>
<p align="justify">Based upon the published information, mine plans,
production records and reserve calculations obtained from operators of
the two mines, the minimum historic production from two of the four
mines indicates 510,291 kilograms (18 million ozs) of silver, 40 million
kilograms (88 million lbs) of copper, and 44 million kilograms (96.8
million lbs) of zinc were produced. Management believes a potential
target grade of 113.4 grams (4 ozs) per ton silver, 1% copper, and 2.5%
zinc is attainable over a potential target tonnage of between 10 and 25
million metric tons of ore grade material. </p>
<p align="justify">The potential quantity and grades commented upon in
the above paragraph are conceptual in nature as they are extrapolated
from historic production and therefore, cannot be relied upon. At
present, there has been insufficient NI 43-101 compliant exploration to
define a mineral resource and it is uncertain if further exploration
will result in the discovery of an economic mineral resource. Investors
are cautioned not to rely solely on this information. Grenville will
continue working with contractors to complete the required NI 43-101
report and other studies that will allow for an economic model to be
developed for the Silveria Properties.</p>
<p align="justify">The technical information contained in this release
has been reviewed by Jeffrey Reeder P.Geo technical advisor for
Grenville Gold and qualified person as defined in National Instrument
43-101.</p>
<p align="justify">In addition, Grenville will issue 500,000 options at
CD$0.60 to certain Directors, Officers and Consultants. The options will
be exercisable for a five year period and expire June 2, 2012. </p>
