Graphite One Files NI 43-101 Technical Report With Indicated Resource of 17.95 Mt at 6.3% Graphite and 154.36 Mt at 5.7% Graphite

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 30, 2015) - Graphite One Resources Inc. (TSX VENTURE:GPH)(GPHOF) ("Graphite One" or the "Company") is pleased to announce the filing on SEDAR of a technical report titled "2015 Indicated And Inferred Mineral Resource Estimate at The Graphite Creek Property, Alaska, United States" dated effective March 17, 2015, prepared in accordance with National Instrument 43-101 ("NI 43-101") on its Graphite Creek Deposit near Nome, Alaska (the "Report"). The Report supports the disclosure made by the Company in its news release of March 17, 2015 updating the mineral resource estimate to 17.95 million tonnes ("Mt") indicated, grading 6.3% graphitic carbon ("Cg"), and 154.36 Mt inferred, with 5.7% Cg, using a 3% Cg cut-off grade ("COG").

The Graphite Creek Deposit is 29km (18 miles) from a seasonal road and approximately 113km (70 miles) from the port of Nome which could be accessible from the deposit by either land or water. The Graphite Creek Property comprises 129 claims totaling 6,799 hectares on the Seward Peninsula of Alaska. Mineralization at the Graphite Creek Property is characterized by coarse crystalline (large flake) graphite (greater than 80 mesh) within graphite-bearing schist(s).

Highlights of the Updated Mineral Resource Estimate:

  • Indicated Mineral Resource of 17.95 Mt at 6.3% Cg and an Inferred Resource of 154.36 Mt of 5.7% Cg, both at 3% COG, makes the Graphite Creek deposit the largest published graphite resource in the United States.

  • A 14% increase in grade within the area of 2014 infill drilling as shown by the new Indicated Mineral Resource from the previous Inferred Resource grade (5.54% to 6.3% Cg COG).

  • The 2014 drilling program further confirmed positive continuity of near surface, higher grade graphite within a simple geological setting, moving 11% of the previous Inferred resource to the Indicated resource category.

  • High-grade graphite mineralization is present at the surface and has been extended to depths of over 200 m by drilling.

  • The indicated resource lies within 730 m of strike length along the 4.8 km inferred resource area, further definition drilling is proposed.

  • The deposit remains open along strike in both the east and west directions, as well as down dip.

This resource estimate recommends using a 3.0% Cg cut-off grade for the base case to be consistent with its conservative approach of resource recovery of 80 to 95% Graphite concentrate with average selling price of USD$1,400/tonne.

The tonnage and in situ graphite (metric tonnes) have been rounded off to the nearest thousand, and therefore may not tally due to rounding.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve.
