Drill Results for this Step-out Hole (22GC079) Include 58.2m of 4.18% Graphite

Feasibility Study Drill Work Shows Deposit Remains Open to the East, West, and Down Dip

February 7, 2023 – Vancouver, British Columbia –Graphite One Inc. (GPH: TSX‐V; GPHOF: OTCQX) (“Graphite One”, “G1” or the “Company”), planning a complete domestic U.S. supply chain for advanced graphite materials, is pleased to announce drill results from its 2022 Field Program at its Graphite Creek Property (“Graphite Creek” or the “Property”), located in the Kigluaik Mountains on the Seward Peninsula approximately 60 kilometers (37 miles) north of Nome, Alaska. Graphite Creek is living up to its designation by the US Geological Survey as the largest and highest grade graphite resource in the United States[1] [2].

Conducted from June to September 2022, the field program was comprised of increasing the field camp capacity, completing key environmental baseline studies, and drilling 1,940 meters of core for resource definition as well as 210 meters of geotechnical drilling for mill site and tailing area determination.

The 2022 drill results will be used to update the most recent Measured, Indicated and Inferred results published in the Graphite One Project Preliminary Feasibility Study released October 13, 2022 (the “PFS”).  The Company expects to release updated Measures, Indicated, and Inferred results by the end of the first quarter 2023.

Select Drill Results Include:

  • 22GC071 returned 18.5m of 4.7% Cg, 22.2m of 6.8% and 20m of 6.7% Cg starting from 19m downhole.
  • 22GC072 returned 31.7m of 5.6% Cg, and 37.6m of 5.2% Cg starting from 62m downhole.
  • 22GC073 returned 3.8m of 7.6% Cg, 27.6m of 5.1%, 26.4m of 6.2%Cg and17.3m of 4.3% Cg starting from 13m downhole.
  • 22GC075 returned 10.5m of 7.7% Cg, 32.9m of 6.4% Cg and 2.1m of 12.0% Cg starting from 3m downhole.
  • 22GC076 returned 53.1m of 7.5% including 12.3m of 11.5% Cg including 2.8m of 25.6% Cg starting from 72m downhole.
  • 22GC079 located 2 km west of previous closest drilling returned 31.8m of 3.4% Cg, including 6.3m of 6.7% Cg, 21.5m of 2.6% Cg, 10.7m of 2.6%Cg, and 13m of 5.4%Cgstarting 5m below the surface.

Interpretation of Results:

  • Core drilling in the deposit area continued to encounter visible graphite minerization over wide intervals, consistent with previous drilling. 
  • Hole 22GC079, drilled 2 km west of previous resource drilling and 4 km west of the PFS pit boundary, showed significant intervals above mill cut-off grade. Selected intervals totaled 58.2 m of 4.18% graphite.
  • The deposit remains open to the West, East, and down dip. 
  • 2022 drilling targeted extending inferred resource to the west and upgrading inferred resources to measured and indicated around the PFS pit area.
  • All holes drilled in the proposed North pit wall encountered significant zones of graphite which will likely expand the pit to the North.

“Our 2022 drill results continue to demonstrate excellent continuity over the length of the anomaly, and we look forward to releasing new resources numbers shortly,” said Anthony Huston, CEO of Graphite One.  “Our 2022 drilling results come at a critical point as we continue to see the demand for graphite increase.  We believe this deposit could potentially supply a major portion of North America’s graphite demands far into the future.”

Feasibility Study Update:

With the positive results of the PFS, Graphite One has begun work on the Graphite Project Feasibility Study (the “FS”).  The lack of United States’ domestic anode material suppliers combined with the projected increase in demand for electric vehicle anode materials has prompted Graphite One to investigate increasing the designed production capacity to be used in the FS.  

Graphite One plans to complete a total of 20,000 meters of drilling in 2023 and 2024, subject to financing, with the objective of increasing the annual concentrate production for the upcoming FS compared to that assumed in the PFS. 

“We are very excited about the upcoming summer program.  We will be shifting gears this year and focusing on completing much more drilling during our 2023 summer program. We are well situated for this work, having increased the capacity of the camp at Graphite Creek from 24 to 60 people last year.”  said Mike Schaffner Sr. Vice President of Mining “We will also be switching from a helicopter-based drilling program to a road-based drilling program.  With the large amount of fog and rain in the area, we expect to see significant improvements in the amount of drilling we can complete in the summer season with significantly reduced costs”.

QA/QC Program

Graphite One maintains a rigorous QA/QC program with respect to the preparation, shipping, analysis and checking of all samples and data from the Property. Quality control for drill programs at the Company’s projects covers the complete chain of custody of samples, including verification of drill hole locations (collar surveys and down-hole directional surveys), core handling procedures (logging, sampling, sample shipping) and analytical-related work, including duplicate sampling, “check analyses” at other laboratories and the insertion of standard and blank materials. The QA/QC program also includes data verification procedures.

Mr. Andrew K. Angel, P. Geo, with Alaska Earth Sciences, Inc. provided oversight to the 2022 drilling and sampling program. Mr. Angel is a Qualified Person as defined under NI 43‐101 and has reviewed and approved the technical content of this release.

Graphite One’s Supply Chain Strategy

With the United States currently 100 per cent import dependent for natural graphite, Graphite One is planning to develop a complete U.S.-based, advanced graphite supply chain solution anchored by the Graphite Creek resource. The Graphite One project plan includes an advanced graphite material and battery anode manufacturing plant expected to be sited in Washington State integrated with the development of the Property. The plan includes a recycling facility to reclaim graphite and the other battery materials, to be co-located at the Washington State site, the third link in Graphite One’s circular economy strategy.

About Graphite One Inc.

GRAPHITE ONE INC. (TSX‐V: GPH; OTCQX: GPHOF) continues to develop its Graphite One Project (the “Project”) to become an American producer of high-grade anode materials that is integrated with a domestic graphite resource.  The Project is proposed as a vertically integrated enterprise to mine, process and manufacture anode materials primarily for the lithium‐ion electric vehicle battery market.  As set forth in the Company’s 2022 Pre-Feasibility Study, graphite mineralization mined from the Company’s Graphite Creek Property, situated on the Seward Peninsula about 60 kilometers north of Nome, Alaska, would be processed into concentrate at an adjacent processing plant.  Natural and artificial graphite anode materials and other value‐added graphite products would be manufactured from the concentrate and other materials at the Company’s proposed advanced graphite materials manufacturing facility expected to be located in Washington State.  The Company intends to make a production decision on the Project upon the completion of a Feasibility Study.
