Zenyatta Ventures Ltd.: Robust Initial Resource Estimate for Albany Graphite Deposit
December 2, 2013 (Source: Marketwired) — Zenyatta Ventures Ltd. (“Zenyatta” or “Company”) (TSX VENTURE:ZEN) is pleased to announce the results of its initial National Instrument (“NI”) 43-101 compliant resource estimate prepared by Roscoe Postle Associates Inc. (“RPA”) on the Company’s 100 percent owned Albany graphite deposit located in northeastern Ontario, Canada.
RPA estimates Indicated Mineral Resources delineated to date total 25.1 million tonnes (“Mt”) at an average grade of 3.89% graphitic carbon (“Cg”), containing 977,000 tonnes of Cg. In addition, Inferred Mineral Resources delineated to date are estimated to total 20.1 million tonnes at an average grade of 2.20% Cg, containing 441,000 tonnes of Cg. A 3D geological deposit model showing the preliminary pit shell, West and East Pipes can be found at the following link Graphite Project on the Company’s website.
Aubrey Eveleigh, President and CEO stated, “We are extremely pleased with initial results from the independent work completed by RPA displaying a very robust graphite deposit. The Mineral Resource estimate shows a significant amount of graphitic carbon totaling 977,000 tonnes Indicated and an additional amount of 441,000 tonnes Inferred. It’s significant to note that the graphite mineralization extends below the preliminary pit shell and is also open at depth but not included in these Mineral Resource estimates. Zenyatta will continue with market studies and now engage an independent consultant to complete a Preliminary Economic Assessment (“PEA”) by the second quarter of 2014.”
Mineral Resources are contained within two vertical pipes spaced approximately 250 m apart. The East Pipe is approximately 300 m long in the NW-SE direction by 50 m wide by 600 m deep, where it remains open. An overprint of lower grade mineralization occurs around the East Pipe for a collective width of 150 m in the NE-SW direction. The West Pipe is approximately 300 m long in the NE-SW direction by 175 m wide by 500 m deep, where it also remains open. Both pipes are cut by 10 m to 60 m thick barren sills located approximately 200 m to 300 m below surface.

|Tonnage||Grade||Tonnes Graphitic Carbon|
|(Mt)||(% Cg)||(t Cg)|
- CIM definitions were followed for Mineral Resources.
- Cg – graphitic carbon
- Mineral Resources are estimated at a cut-off grade of 0.6% Cg.
- Mineral Resources are estimated using a long-term price of US$8,500 per tonne Cg, and a US$/C$ exchange rate of 1.0.
- Bulk density is 2.6 t/m3 in the pipes and 2.65 t/m3 in the overprint of the East Pipe.
- Mineral Resources are constrained by a preliminary pit-shell generated in Whittle software.
- Numbers may not add due to rounding.

Resource Estimation Details: The Albany Graphite Project drill hole database includes 60 NQ size diamond core holes totaling 24,626 metres drilled prior to November 15, 2013. Drill hole cross sections and plan views were interpreted to construct three-dimensional wireframe models of the pipes using the descriptive logs and overprint mineralization using a nominal cut-off of 0.4% Cg. Assay intervals were composited to two metre lengths. Grades were estimated using ordinary kriging. Resources were classified as Indicated or Inferred based on drill hole spacing and the apparent continuity of mineralization. Indicated Resources are confined within those parts of the pipes located above the barren sills. All material below the sills or within the overprint mineralization is classified as Inferred. Only material located within the preliminary pit shell generated in Whittle software is included in estimated Mineral Resources. Mineral Resources are reported at a cut-off grade of 0.6% graphitic Cg based on drill results available to November 15, 2013. A NI 43-101 technical report documenting the Mineral Resource estimate will be filed on SEDAR within 45 days.

A relatively low cut-off grade of 0.6% Cg was used to report Mineral Resources, compared to flake graphite Cg projects, due to an assumed market price of $8,500 per tonne Cg product for the Albany graphite product. Zenyatta and its technical advisors believe that hydrothermal graphite from the Albany Graphite Project will command higher prices than flake graphite products, based on process test work completed earlier this year. Results suggest that high-purity graphitic material can be produced, suitable for competing in the $13 billion (1.5 million tonnes annually) synthetic graphite market. Synthetic high purity graphite commands higher market prices in the range of $7,000 to $20,000 per tonne for >99.9% Cg carbon. Bench scale testing of the Albany graphite material using a caustic bake method at SGS Inc. has demonstrated a product at 99.99% carbon purity with very good crystallinity.
The global trend in graphite markets is to develop products for technological applications that require extraordinary performance using ultra-high purity graphite powder at an affordable cost. High purity is gaining prominence at a time when Zenyatta discovered a very rare (hydrothermal) graphite deposit, which can be upgraded to 99.99% carbon without the use of aggressive acids like HF and high thermal treatment.
The outlook for the global graphite market is very promising with demand growing rapidly from new applications. It is now considered a strategic commodity by many 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 3,300°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.
Zenyatta’s Albany (Hydrothermal) Graphite Deposit is located in northeastern Ontario, Canada approximately 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 4-5 km from the graphite deposit. The deposit is near surface, underneath glacial till overburden and a thin veneer of Paleozoic sedimentary cover rocks.
