Zenyatta Ventures Ltd.; Electrical Resistivity Test on Albany Graphite Yield Exceptional Results
03 Oktober 2013 - 5:02PM
Zenyatta Ventures Ltd. ("Zenyatta" or "Company") (TSX-V:ZEN) is
pleased to announce results from initial testing to identify the
performance characteristics of Zenyatta's high purity Albany
graphite.
Electrical resistivity ('ER') tests were conducted by a major
U.S. based independent materials testing facility. One of the most
useful characteristics of graphite is its ability to carry electric
current. ER quantifies how strongly a material opposes the flow of
electric current. A low resistivity indicates a material that
readily allows the movement of an electric charge.
Published physics data on electrical resistivity of graphite
typically ranges from .003 to .060
ohm-centimetres. Zenyatta's graphite showed a resistivity of
.0034 ohm-centimetres for a compressed bulk
graphite test bar measuring 50x12x2.4mm. These results are
comparable with high grade synthetic graphite and represent a value
at the top of the range. The resistivity test was conducted on a
random sample of Zenyatta's high purity Albany graphite without any
attempt to select particle size or to align the graphite crystals
to optimize the test results. These initial test results are very
encouraging and indicate that Zenyatta's high purity graphite
should be competitive with the best graphite available for a
variety of applications including electronic components and
batteries.
Don Hains, P. Geo. industrial minerals technical advisor to
Zenyatta stated, "These results are very promising, especially
considering that tests were run on as-produced sample material from
the initial bench-scale test work. The optimization work now
underway should yield even better results in terms of graphite
properties."
Resistivity is significantly influenced by the degree of
crystallinity of the graphite, particle orientation and
temperature. Higher crystallinity results in lower resistivity
and therefore higher conductivity. Resistivity also varies
considerably when measured axial or perpendicular to the c-axis of
the graphite crystal. The resistivity of conductors, like
graphite, depends strongly on a lack of impurities in the material,
an important fact which makes them valuable in
electronics. Previous mineralogical studies show that
Zenyatta's Albany graphite material to be of high quality and
containing minor amounts of impurities (feldspar and quartz) which
can be easily removed to produce an ultra-high purity graphite
product.
Aubrey Eveleigh, President and CEO stated, "The Company is
extremely pleased with these preliminary electrical resistivity
results. The data indicate that Zenyatta's high purity Albany
graphite could be suitable for a wide range of
applications. This is another very important step and further
evidence of the high quality nature of the unique hydrothermal
graphite discovery. Further results on Zenyatta's graphite
crystallinity with associated scanning electron microscope
photographs are nearing completion and will be released next week
from the work being carried out at a Canadian university."
Zenyatta will continue to test the characteristics of the Albany
graphite at various laboratory facilities in the U.S., Europe and
Canada where the required instrumentation is
available. Additional test results will be reported when
received.
Zenyatta continues to explore its 100% owned Albany
(Hydrothermal) Graphite Deposit located in northern Ontario,
Canada, and anticipates releasing additional drill results in the
near-term. A NI 43-101 resource estimate by RPA is scheduled
for mid 4Q/13, and the Company remains well funded. A
Preliminary Economic Assessment (PEA) is expected to be concluded
in 1Q/14. In preparation for a PEA, Roskill Information
Services Ltd. has been retained to undertake a detailed world
graphite marketing study and SGS Canada Inc. are to provide an
optimized flow sheet after processing a 5 tonne mini-bulk
sample.
Zenyatta's Albany graphite deposit is located 30km north of the
Trans Canada Highway, power line and natural gas pipeline near the
communities of Constance Lake First Nation and Hearst in northern
Ontario, Canada. A rail line is located 70km away and an
all-weather road approximately 4-5km from the graphite
deposit. The deposit is near surface, underneath glacial till
overburden and a thin veneer of Paleozoic sedimentary cover
rocks.
The outlook for the global graphite market is very promising
with demand growing rapidly from new applications. It is now
considered one of the more strategic elements by many leading
industrial nations, particularly for its growing importance in high
technology manufacturing and in the emerging "green" industries
such as electric vehicle components. The application for graphitic
material is constantly evolving due to its unique chemical,
electrical and thermal properties. It maintains its stability and
strength under temperatures in excess of 3,500°C and is very
resistant to chemical corrosion. It is also one of the lightest of
all reinforcing elements and has high natural lubricating
abilities. Some of these key physical and chemical properties make
it critical to modern industry. The world trend is to develop
products for technological applications that need extraordinary
performance using ultra-high purity graphite powders.
