Summary
1. Procedures
Two samples, identified as Sample #1 and #3, were submitted to SGS Mineral Technologies for
mineralogical examination. The purpose of the investigation was to determine the overall
mineralogy and the form of graphite.
One polished thin section was prepared from each sample. Each section was examined optically
with a petrographic microscope under incident (reflected) and transmitted light at SOx to SOOx
magnifications. The mineral assemblage and modal abundance of the sample were determined
optically and are approximate.
A list of minerals and abbreviations are given in Table 1.

2. Mineralogical Results
The sample consists mainly of carbonates, mica and graphite; minor vesuvianite and clays were
also observed. The overall mineralogy and textural characteristics of the minerals are given in
Tables 2 and 3. Photomicrographs from the optical microscope are presented in Figures 1 and 2.

Comments
Graphite ranges from 0.1 to 1.5 mm in length, but reaches up to 2.5 mm
in length. It occurs as subhedral, elongated particles and less commonly
as platy laths.
Graphite occurs interstitial to calcite and mica; that is between the grain
boundaries of the minerals.
Graphite also occurs as inclusions in, or partially locked by, calcite and
mica. It is locally bended and follows possibly some foliation.
Graphite occurs commonly as isolated dispersed inclusions.
All graphite is crystalline. There was no amorphous graphite observed in
the sample.
Mica occurs as platy, tabular and prismatic grains. It varies between 0.3
and 2 mm in length. Locally mica forms decussate texture; that is
randomly oriented or aligned segregated particles.
It exhibits more granular textures with calcite.
A minor proportion of mica carries fine-grained calcite inclusions.
Carbonates (likely calcite) occur as subhedral and stubby grains. They
range in size from 0.1 mm to 2 mm and exhibit granular textures. Calcite
hosts fine-grained graphite, typically <0.4 mm in size.
Calcite forms polycrystalline aggregates.
' Clay minerals occur interstitial to calcite and may replace possibly mica.

Graphite ranges from 0.1 to 2 mm in length. It occurs as subhedral,
tabular flakes, prismatic and elongated.
Graphite occurs interstitial to calcite and mica.
Minor graphite also occurs as inclusions in calcite and mica, or partially
locked in these minerals. It is locally bended and follows possibly some
foliation. Graphite occurs commonly as isolated dispersed inclusions.
All graphite is crystalline. There was no amorphous graphite observed in
the sample.
Carbonates (likely calcite) occur as subhedral and stubby grains and also
form polycrystalline aggregates. They range in size from 0.1 mm to 2.5
mm and exhibit granular textures. Carbonates host fine-grained graphite.
typically <0.4 mm in size.
Mica occurs as platy. tabular and prismatic grains. It varies between 0.3
and 2 mm in length. Locally mica forms decussate texture, but exhibits
more granular textures with calcite.
A minor proportion of mica carries tine-grained calcite and graphite
inclusions.
Vesuvianite occurs as subhedral and stubby grains. It ranges in size from
0.2 mm to I mm and it is disseminated in the sample. It also occurs as
fine-grained inclusions «0.3 mm) in calcite graphite .

Summary and Mineralogical Overview
t
The samples consist mainly of carbonates, mica, graphite, vesuvianite and clays. Carbonates are
likely calcite in composition, and mica is phlogopite.
Graphite occurs only as crystalline particles. However, it is noted that some calcite particles
might be partially graphitized, as it appears by their cloudy appearance and grey to dark
colouration.
Graphite occurs as both tabular flakes and prismatic particles, depending on the orientation that
were cut from the rock. It occurs mainly interstitially to calcite and mica, and less commonly as
locked or partially locked particles in calcite and mica.

-3The attached Report by SGS Minerals Services, Lakefield Ontario Site, was
authorized by the writer in order to detennine the overall mineralogy and
the fonn of graphite.. The writer currently has (since 1998) owned the
mining rights to this property, under mineral claim number 1203950.
Interest in this graphite deposit has been renewed in 2008, and the writer
was requested to detennine the quality of the graphite, and in particular, the
% of "flake graphite" vs. "amorphous graphite" in the graphitic
mineralization.
Keep in mind that processed amorphous graphite at
present sells on the world market for Approximately $100.00 per tonne,
and "flake graphite" for approximately $ 300.00 per tonne. Thus the
reason for the requested analysis.

3.0 LOCATION OF TWO GRAPHITE SAMPLES
(described in the attached report by SGS Mineral Services)
In 1998 the writer obtained an OPAP grant from the Ontario Government to
further explore the above graphite prospect, which had not been
investigated for many years.
As follow-up (in 1999) a second OPAP
Grant was obtained by the writer as follow- up to the work completed in
1998.
A number of geological and geophysical drawings were
completed, covering the work completed in 1998 and 1999, by the writer.
On June 26, 2008, the writer traveled to the BeidelmanlLyall Graphite
Property, near Griffith, Ontaro, to select two representative samples of the
Graphic ore for testing.
On the same day the samples were transported to
the office of SGS Mineral Services, Lakefield Ontario.
The location of
the two samples in question are plotted as shown on page 4 of this report
nnder A. and B.
-t.{-
These two samples (No.1 and No.3) are plotted on the following maps:
