Zenyatta Ventures Ltd.; Electrical Resistivity Test on Albany Graphite Yield Exceptional Results
October 3, 2013 (Source: Globe Newswire) — 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.
