Zenyatta Ventures Ltd; University of Sussex Successfully Enhances Performance of Rubber Composites using Zenyatta Graphene Derived from Albany Graphite
(Thomson Reuters ONE) -
THUNDER BAY, ON--(Marketwired - April 06, 2017) - Zenyatta Ventures Ltd.
("Zenyatta" or "Company") (TSX VENTURE: ZEN) (OTCQX: ZENYF) is pleased to
announce successful initial test results from research carried out by Dr. Alan
Dalton at the University of Sussex, UK ("Sussex") using graphene converted from
the Company's high-purity graphite. Sussex tested the use of Zenyatta graphene
in rubber composite and emulsion applications.
Rubber Composite Applications
Sussex easily exfoliated Zenyatta graphite via sonication to produce graphene
which was then homogenously dispersed into a rubber composite. A several fold
improvement in the electrical and thermal properties of the rubber composite
along with increased strength and elasticity was realized by adding as little as
0.5% Zenyatta graphene. Sussex researchers have turned to nano-materials like
graphene to develop high performance rubber composite sensors. The resulting
material demonstrated impressive performance as sensors which can detect motions
as subtle as those associated with breathing and pulse.
Dr. Alan Dalton, Professor of Experimental Physics at Sussex noted, "The
exfoliation of Zenyatta graphite was very clean with the production of mostly
monolayer and bilayer graphene." Dr. Dalton further stated, "Our initial results
using Zenyatta graphene in rubber composites show exceptional motion sensitivity
to mechanical stress which is critical for sensor applications. We will be
investigating the use of these composites in several other applications in
conjunction with the appropriate industrial partners."
Rubber composites with multiple properties have potential sensor applications in
wearable sports clothing and medical devices as health monitors.
Dr. Bharat Chahar, VP Market Development for Zenyatta noted, "This further
confirms the distinct and desirable properties of Albany graphite for conversion
to graphene which was previously recognized by scientists in Israel, Japan and
Canada. Dr. Chahar added that "We continue to find that the unique properties of
our graphite enable easier production of consistently high quality and easily
dispersible graphene which is opening doors for new and important applications,
especially composites. Zenyatta recently achieved similar successful results
using our graphene in concrete composites with Dr. Oren Regev at Ben-Gurion
University."
The Company continues to provide high-purity graphite samples to potential end-
users to allow them to assess the consistent quality of our material in their
current graphene product developments.
Emulsion Applications
Scientists at Sussex have also developed techniques to produce solid-stabilized
water-in-oil suspensions known as emulsions. Exfoliated graphite or graphene can
be used as the stabilizing solid for these emulsions. These emulsions can then
be used in new applications where the control of electrical and thermal
properties is critical for performance. Examples of such applications include
inkjet printing, thin wires, stress sensors and supercapacitors.
Sussex has developed a method to produce the graphene directly in the emulsion,
but the homogeneity and yield of the Zenyatta produced graphene determined the
success and usefulness of the suspension. In the past, the low yields and lack
of homogenous graphene from other sources resulted in insufficient concentration
of graphene and required further processing with a centrifuge. Recent results
with Zenyatta's Albany graphite demonstrated superior homogenous graphene
production with high yields thus allowing production of conductive liquid
suspensions directly. These emulsions show excellent conductivity controls at
graphene concentrations of approximately 1% or less.
Sussex is a world-leading research university near Brighton, United Kingdom. The
high quality research-led university delivers internationally recognized, high-
quality research. Zenyatta and Sussex are now working to scale-up testing while
developing plans to prove out the viability of applications.
Zenyatta Ventures Ltd. is developing the Albany Graphite Deposit situated in
northeastern Ontario, Canada. The deposit is a unique type of igneous-hosted,
fluid-derived graphite mineralization contained in two large breccia pipes. The
Company is seeking end users for their graphite and graphene and is working with
several collaborative partners including the development of a graphene enhanced
concrete. Other potential markets for graphite include Li-ion batteries, fuel
cells and powder metallurgy. 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 Albany graphite deposit is situated 30 km north of the Trans-Canada Highway,
power line and natural gas pipeline near the communities of Constance Lake First
Nation and Hearst. A rail line is located 70 km away with an all-weather road
approximately 10 km from the graphite deposit. The world trend is to develop
products for technological applications that need extraordinary performance
using ultra-high purity graphite powder at an affordable cost. Albany graphite
can be upgraded with very good crystallinity without the use of aggressive acids
(hydrofluoric) or high temperature thermal treatment therefore having an
environmental advantage over other types of upgraded high-purity graphite
material.

CAUTIONARY STATEMENT: This analysis does not represent a statistically large
sample size. Furthermore, these positive results do not mean that Zenyatta can
extract and process Albany graphite for graphite applications on an economic
basis. Without a formal independent feasibility study, there is no assurance
that the operation will be economic. The Company has completed a July 9, 2015
Preliminary Economic Assessment which indicates an open pit mine life of 22
years (excludes underground resource which is open at depth) producing 30,000
tonnes purified graphite per annum (see Zenyatta press release of 1 June 2015).
The PEA is preliminary in nature, it includes inferred mineral resources that
are considered too speculative geologically to have the economic considerations
applied to them that would enable them to be categorized as mineral reserves,
and there is no certainty that the preliminary economic assessment will be
realized. Neither TSX Venture Exchange nor its Regulation Services Provider (as
that term is defined in the policies of the TSX Venture Exchange) accepts
responsibility for the adequacy or accuracy of this release. This news release
may contain forward looking information and Zenyatta cautions readers that
forward looking information is based on certain assumptions and risk factors
that could cause actual results to differ materially from the expectations of
Zenyatta included in this news release. This news release includes certain
"forward-looking statements", which often, but not always, can be identified by
the use of words such as "potential", "believes", "anticipates", "expects",
"estimates", "may", "could", "would", "will", or "plan". These statements are
based on information currently available to Zenyatta and Zenyatta provides no
assurance that actual results will meet management's expectations. Forward-
looking statements include estimates and statements with respect to Zenyatta's
future plans, objectives or goals, to the effect that Zenyatta or management
expects a stated condition or result to occur, including the expected timing for
release of a pre-feasibility study, the expected uses for graphite in the
future, and the future uses of the graphite from Zenyatta's Albany deposit.
Since forward-looking statements are based on assumptions and address future
events and conditions, by their very nature they involve inherent risks and
uncertainties. Actual results relating to, among other things, results of
metallurgical processing, ongoing exploration, project development, reclamation
and capital costs of Zenyatta's mineral properties, and Zenyatta's financial
condition and prospects, could differ materially from those currently
anticipated in such statements for many reasons such as, but are not limited to:
failure to convert estimated mineral resources to reserves; the preliminary
nature of metallurgical test results; the inability to identify target markets
and satisfy the product criteria for such markets; the inability to complete a
prefeasibility study; the inability to enter into offtake agreements with
qualified purchasers; delays in obtaining or failures to obtain required
governmental, environmental or other project approvals; political risks;
uncertainties relating to the availability and costs of financing needed in the
future; changes in equity markets, inflation, changes in exchange rates;
fluctuations in commodity prices; delays in the development of projects; capital
and operating costs varying significantly from estimates and the other risks
involved in the mineral exploration and development industry; and those risks
set out in Zenyatta's public documents filed on SEDAR. This list is not
exhaustive of the factors that may affect any of Zenyatta's forward-looking
statements. These and other factors should be considered carefully and readers
should not place undue reliance on Zenyatta's forward-looking statements.
Although Zenyatta believes that the assumptions and factors used in preparing
the forward-looking information in this news release are reasonable, undue
reliance should not be placed on such information, which only applies as of the
date of this news release, and no assurance can be given that such events will
occur in the disclosed time frames or at all. Zenyatta disclaims any intention
or obligation to update or revise any forward-looking information, whether as a
result of new information, future events or otherwise, other than as required by
law.
