Thunder Bay, ON – Mining – Zenyatta Ventures Ltd. have announced the following significant graphitic carbon (“Cg”) assay results from holes 16 – 24 drilled on the East Pipe of the 100% owned Albany (Hydrothermal) Graphite Deposit, located in northern Ontario, Canada.
The East Pipe graphite mineralization is oval-shaped with dimensions of approximately 150 metres (“m”) in a NE-SW direction by 300 m in a NW-SE direction and to a depth of 500 m. It is showing good vertical continuity and remains open at depth. The East Pipe consists of a higher grade core of graphitic breccia which is typically surrounded by a broad halo of graphite overprinted granite.
• Hole 24 yielded 150.6 m @ 4.8% Cg from 61.0 m to 211.6 m within a wider intersection of 191.0 m of graphite mineralization grading 3.8% Cg from 61.0 m to 252.0 m.
• Hole 23 yielded 96.3 m @ 5.3% Cg from 83.0 m to 179.3 m within a wider intersection of 179.0 m of graphite mineralization grading 3.1% Cg from 62.0 m to 241.0 m.
• Hole 22 yielded 137.0 m @ 5.0% Cg from 63.0 m to 200.0 m within a wider intersection of 198.0 m of graphite mineralization grading 3.5% Cg from 63.0 m to 261.0 m.
• Hole 21 yielded 140.6 m @ 4.8% Cg from 89.0 m to 229.6 m within a wider intersection of 228.0 m of graphite mineralization grading 3.1% Cg from 63.0 m to 291.0 m.
• Hole 20 yielded 128.0 m @ 5.5% Cg from 61.0 m to 189.0 m within a wider intersection of 241.5 m of graphite mineralization grading 3.1% Cg from 61.0 m to 302.5 m.
• Hole 19 yielded 110.0 m @ 4.2% Cg from 66.0 m to 176.0 m within a wider intersection of 176.0 m of graphite mineralization grading 2.7% Cg from 66.0 m to 242.0 m.
• Hole 18 yielded 154.0 m @ 4.8% Cg from 133.0m to 287.0 m within a wider intersection of 258.0 m of graphite mineralization grading 3.1% Cg from 101.0 m to 359.0 m.
• Hole 17 yielded 67.2 m @ 3.0% Cg from 322.0 m to 389.2 m within a wider intersection of 192.4 m of graphite mineralization grading 1.7% Cg from 236.6 m to 429.0 m.
• Hole 16 yielded 62.3 m @ 4.2% Cg from 291.0 m to 353.3 m within a wider intersection of 135.3 m of graphite mineralization grading 2.3% Cg from 258.0 m to 393.3 m.

Aubrey Eveleigh, President and CEO stated “These latest results on the East Pipe continue to demonstrate the excellent vertical continuity and exceptional size potential of the graphite deposit. Graphite intersections appear to be correlating extremely well with the shape of the ground geophysical conductors. Drilling to date on the West Pipe is also showing significant widths of graphitic breccia with great continuity. The current campaign will continue there until sufficient drill holes have been completed to delineate a mineral resource, following which a NI 43-101 compliant resource estimate will be prepared by RPA (formerly Roscoe Postle & Associates Inc.) for both the East and West pipes.”
Holes 10-15 were previously announced and included here for reference:
• Hole 15 yielded 125.0 m @ 4.6% Cg from 132.0 m – 257.0 m within a wider intersection of 300.0 m of graphite mineralization grading 2.2% Cg from 60.0 m to 360.0 m. • Hole 14 yielded 186.0 m @ 4.9% Cg from 146.0 m – 332.0 m within a wider intersection of 426.0 m of graphite mineralization grading 3.0% Cg from 118.0 m to 544.0 m. • Hole 13 yielded 177.0 m @ 5.3% Cg from 138.0 m – 315.0 m within a wider intersection of 219.9 m of graphite mineralization grading 4.5% Cg from 95.1 m to 315.0 m. • Hole 12 yielded 146.0 m @ 5.2% Cg from 95.0 m – 241.0 m within a wider intersection of 195.0 m of graphite mineralization grading 4.0% Cg from 90.0 m to 285.0 m. • Hole 11 yielded 84.9 m @ 5.2% Cg from 460.6 m to 545.5 m within a wider intersection of 203.0 m of graphite mineralization grading 3.0% Cg from 393.0 m to 596.0 m. • Hole 10 yielded 360.8 m @ 5.1% Cg from 49.0 m to 409.8 m.
Six (6) holes have since been completed on the West Pipe, all of which yielded broad intervals of graphite mineralization from visual observations of drill core. All holes were designed to start outside the limit of the indicated geophysical anomaly and angled to help define and confirm the overall geometry of the pipe-like body.
Graphitic carbon analyses for drill holes 25 through 33 will be released once received.
Analytical Protocol
Samples of half core were packaged and shipped directly from Zenyatta’s core shack at the site to the ALS Minerals facility in Thunder Bay, Ontario, for sample preparation (ALS protocol PREP-31B). Each bagged core sample is dried, crushed to better than 70% passing 2mm and a 1000g split of the crushed material is pulverized to better than 85% passing 75 microns for assaying. The sample pulps were then shipped to the ALS Minerals laboratory in Vancouver, British Columbia for assay. ALS Minerals has ISO 9001:2008 and ISO 17025 Accreditation as per the Standards Council of Canada at all of its global laboratories. Graphite assays were obtained using the graphitic carbon by LECO method (ALS protocol C-IR18). A 0.1g sample is leached with dilute hydrochloric acid to remove inorganic carbon (carbonate). After filtering, washing and drying, the remaining sample residue is roasted at 425°C to remove any organic carbon. The roasted residue is finally analysed for graphitic carbon using a high temperature LECO furnace with infra-red detection. The samples were submitted with blanks and certified custom standards inserted into the sample stream to ensure lab integrity.
