Looking at both companies from a Graphite purity test  standard the results here show the following comparisons between the two deposits both companies discovered.

Both news releases show the purities achieved which are pretty much both high quality results yet Zenyatta achieves this with a much easier process quickly then what Northern Graphite has to do to get pure results. Yet the results of both come out high quality for global markets to purchase and both are in Canada being a great stable investment country to do business in.

Zenyatta; Ultra-High Purity of 99.96% Carbon Yielded from Second Series of Tests on Albany Graphite Samples

THUNDER BAY, ONTARIO--(Marketwire - Feb. 5, 2013) - Zenyatta Ventures Ltd. ("Zenyatta" or "Company") (TSX VENTURE:ZEN) is pleased to announce the following significant results from a second series of beneficiation tests conducted at SGS Canada Inc. ("Lakefield") on samples from its 100% owned Albany graphite deposit. Trials using two different leaching processes both yielded results exceeding the target of >99.0% Carbon ("C").

One process yielded 99.7% C while another different and cheaper process yielded an exceptional purity of 99.96% C. This is further confirmation of earlier mineralogical studies that showed the Albany 'vein-type' graphite material to be of high quality and containing minor amounts of impurities. The ability to produce a natural graphite product equivalent in purity to the highest grade synthetic graphite using low-cost conventional processing techniques will allow Zenyatta to target the growing market in high value-added graphite applications.

Aubrey Eveleigh, President and CEO stated, "Achieving these ultra-high purity carbon values at such an early stage from a simple and relatively inexpensive process is truly remarkable. This large 'vein-type' graphite deposit appears to be 'one of a kind' globally in both size and quality." Eveleigh also stated, "With accelerated global interest in the Albany graphite deposit, Zenyatta will continue to discuss the merits of the project with potential strategic partners, including graphite end-users."

Natural graphite material has varying levels of quality depending on the type (vein, flake or amorphous). The degree of purity can vary greatly, which heavily influences the use of the material in applications and its pricing. Carbon purity of natural graphite can generally range from 70.0% all the way to 99.0%, whereas synthetic graphite is usually greater than 99.0%. Given the ultra-high purity at Zenyatta's Albany project, the Company will be positioning the material to compete in the $13 billion (1.5 million tonnes annually) synthetic market.

Synthetic graphite is significantly more expensive to make but commands the highest market prices due to its purity. It can cost $4000 - $5000 per tonne (99.5% purity) to produce but can be sold for $7000 - $9000 per tonne. Ultra-high purity (99.9%) graphite can demand a price of $20,000 - $30,000 per tonne. Processing and purification of natural graphite has improved greatly in recent years and projects with initial high purity graphite, like the Albany vein-type, require less purification and therefore lower cost to produce.

Northern Graphite Successfully Scales Up Graphite Purification Process
Bench scale tests produce 99.99%Cg spherical graphite
November 8, 2012 – Northern Graphite Corporation (NGC: TSX-V, NGPHF: OTCQX) is pleased to announce that ongoing metallurgical testing by Hazen Research has succeeded in purifying spherical graphite from the Bissett Creek deposit up to 99.99% graphitic carbon (“Cg”) and large flake graphite to 99.83% Cg. These bench scale tests are the first step in demonstrating that the laboratory process developed by Northern can be scaled to commercial levels.
Hazen Research’s initial mandate was to test the laboratory process developed by Northern’s research partner in Canada, on bench scale models of commercial units. The trials were highly successful in purifying spherical graphite to levels ranging from 99.93% Cg to 99.99% Cg. The requirements of battery manufacturers vary in particle size and purity with the latter specification usually being in the 99.9 to 99.95% Cg range. Large flake graphite was purified to levels ranging from 99.73 to 99.83%Cg with further improvements possible.
The next steps will be to further scale up the process in a Pilot Plant test that will enable Hazen to define operating parameters at a commercial level and to estimate capital and operating costs. As part of this process, Northern and Hazen are presently working with an equipment manufacturer to identify the matching full scale commercial unit that can be modified to suit the process requirements. The ultimate objective is to define a purification process that works not only with spherical graphite for battery use, but also flake graphite and micronized flake graphite for other applications requiring high purity.
