Valterra Resource Corporation (TSX VENTURE:VQA)(FRANKFURT:3VA) ("Valterra")
reports that recent surface and trench sampling is confirming the high grade
nature of the Bobcaygeon Graphite Property, located 130 kilometres due northeast
of Toronto. Ground EM-MAG-IP geophysical surveys have been completed on 60% of
the 11 line-kilometre grid and the preliminary IP chargeability within the
Discovery Zone area has outlined an open-ended, near surface anomaly covering
480m x 350m, plus additional nearby features and other zones of potential
interest have been detected. Additional ground has been staked, bringing the
Valterra holdings to over 140 sq. km. The company is planning a near-term
diamond drill program and a more extensive regional exploration program to
further evaluate the large property package.
The discovery trench opened in December identified a 20m lateral exposure of
high grade graphite with trenching bottoming in graphite suggesting a minimum
thickness of this lens at 1.5m. The trenching yielded highlighted assay results
from 7.76% C(g) to 36.8% C(g).

----------------------------------------------------------------------------
Sample# Discovery Trench Description C(g) %
----------------------------------------------------------------------------
960540 Graphite (1.5m chip channel in face) 36.8
----------------------------------------------------------------------------
960541 Graphite (1.4m chip channel in face) 20.2
----------------------------------------------------------------------------
960061 Graphite-quartz seams (0.7m chip channel in face) 14.6
----------------------------------------------------------------------------
960542 Graphite seams in amphibolite (0.5m chip channel in
face) 8.7
----------------------------------------------------------------------------
960513 Quartz vein with coarse graphite seams (grab) 7.76
----------------------------------------------------------------------------
Exploration activities included the following:
-- Discovery Zone Trenching - shallow trenching exposed visually coarse-
looking graphitic beds and seams measuring up to 20m of strike-length x
greater than 1.5m thickness x 45 degrees dip (SSE).
-- Ground Geophysics - approximately 11 line-kilometres of grid has been
surveyed by EM, MAG and IP geophysics by JVX Ltd. Preliminary findings
are very encouraging including about 480m x 350m of open-ended, near
surface conductive anomalies co-incident with the Discovery Zone.
-- Sampling - over 80 grab, chip, and channel samples have been collected
in trenches and outcrops and sent for Au-ICP63-Graphite analyses.
-- Claims - Valterra has almost tripled the land package since acquiring
the property in June of 2012 and now controls +140 sq. kilometres.
-- Metallurgy - Phase III analyses by SGS Lakefield is progressing for a
+20kg grab sample collected in May 2012. Test work includes a cleaner
flotation circuit aimed at increasing the concentrate grade to +95% C(g)
and optical mineralogy work is scheduled on sub-samples of the different
concentrate size fractions to better assess individual graphite
particles.

About Graphite
Graphite is a naturally occurring form of carbon with wide-ranging and unique
physical properties. Graphene comes from graphite and is one of the strongest
known substances which when developed industrially, will be a replacement for
several expensive electronic components such as silicon semi-conductors. There
are three primary graphite occurrences naturally - vein, flake, and amorphous
where the highest quality product can sell for over $2,000 per tonne. In pricing
graphite, the flake size is a key factor with the large flake (greater than
.178mm) ores commanding the highest prices in markets dominated by
multi-national eco-automobile manufacturers, high-tech industries and nuclear
energy companies. Recent pricing and demand increases have spurred numerous
exploration and investment opportunities in the graphite market.
The Province of Ontario is an excellent locale to explore owing to superior
geology, geoscience knowledge, infrastructure, political stability and tax
incentives. Several projects are advancing in the graphite field including
Northern Graphite Corporation, Zenyatta Ventures Inc. and Ontario Graphite Ltd.

(1) Activation Laboratories Ltd., Ancaster Ontario - 5DC-Graphitic Analysis: A
0.5 g sample is subjected to a multistage furnace treatment to remove all forms
of carbon with the exception of graphitic carbon. Either a resistance or
induction furnace are used for analysis. The inductive elements of the sample
and accelerator couple with the high frequency field of the induction furnace.
The pure oxygen environment and the heat generated by this coupling cause the
sample to combust. During combustion, carbon-bearing elements are reduced,
releasing the carbon, which immediately binds with the oxygen to form CO and
CO2, the majority being CO2. Carbon is measured as carbon dioxide in the IR cell
as gases flow through the IR cells. Carbon dioxide absorbs IR energy at a
precise wavelength within the IR spectrum. Energy from the IR source is absorbed
as the gas passes through the cell, preventing it from reaching the IR detector.
All other IR energy is prevented from reaching the IR detector by a narrow
bandpass filter. Because of the filter, the absorption of IR energy can be
attributed only to carbon dioxide (CO2). The concentration of CO2 is detected as
a reduction in the level of energy at the detector.
