M&I Increase Comes After US Geological Survey Report Identifies Graphite Creek Deposit “as Among the Largest in the World.”

March 13, 2023 – Vancouver, British Columbia –Graphite One Inc. (TSX‐V: GPH; OTCQX: GPHOF) (“Graphite One” or the “Company”), planning a complete domestic U.S. supply chain for advanced graphite materials, is pleased to announce the results of the 2022 drilling program and updated resource estimate, which shows an increase of 15.5% in Measured and Indicated tonnage with a corresponding increase of 13.1% in contained tonnes of graphite.  The Measured and Indicated Resources now stand at 37.6 M tonnes at 5.14% graphite, with an Inferred Resource of 243.7 M tonnes at 5.07% graphite.

“We’ve been very consistent about the potential we see in Graphite Creek,” said Anthony Huston, President and CEO of Graphite One.  “The recognition by USGS coupled with this increase in our Measured and Indicated Resources and the fact that we have explored only 26% of our graphite anomaly underscores that Graphite Creek is truly a generational resource.”

“These strong results from our 2022 program will assist in developing our 2023 drilling plan,” said Mike Schaffner, Senior Vice President, Mining, “and the continued expansion of our Graphite Creek resource will support our plan to quadruple the annual production from our PFS study.”

The updated resource did not include Hole 22GC079, drilled 2.1 km west of the current block model, which encountered 58 meters of 4.18% graphite, due to distance constraints used in the block model. The planned 2023 drilling program will target doubling the measured and indicated resources and increasing the inferred resource by infill drilling along trend to Hole 22GC079.

The resource updates from Graphite One’s October 2022 Pre-feasibility Study (“PFS”) and the 2022 Drilling Program come after the US Geological Survey report that states:

“The Graphite Creek graphite deposit, located in the Kigluaik Mountains 60 km north of Nome on the Seward Peninsula, Alaska, is the largest known flake graphite resource in the USA and is among the largest in the world.”[2]

Graphite One’s PFS was based on a proven and probable reserve that utilized 7% of the anomaly’s strike length.  This updated Measured, Indicated and Inferred resource is based on drilling 26% of the surface area of the anomaly.  The planned 2023 Drilling Program will continue to delineate the scope and size of the resource, as the Graphite Creek deposit remains open to the West, East, and down dip.

Marketing Awareness Program

As part of Graphite One’s ongoing strategy to raise the profile of the Graphite One Project to investors, the Company has entered into marketing agreements with CFN Media and Outside The Box Capital Inc. to provide investor and market outreach campaigns for a period of up to 12 months.  Subject to the approval of the TSX Venture Exchange, the agreements’ effective start date will be March 13, 2023.

The Company will pay CFN Media US$8,000 per month for 12 months plus expenses of up to US$20,000 per month. The agreement may be terminated without penalty after 90 days.

The Company will pay Outside The Box Capital Inc. CA$100,000 for a 6-month period plus expenses of up to CA$25,000 per month for the duration of the agreement.

To the best of the Company’s knowledge, neither CFN Media, Outside The Box Capital Inc. nor any of its principals currently own any common shares in the Company.

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. 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.
