Graphite One Completes 2022 Field Program with 2,090m of drilling for the Feasibility Study

2 Kilometer Step Out from Known Resource Encounters Graphite Mineralization

VANCOUVER, Oct. 6, 2022 - Graphite One Inc. (TSX?V: GPH) (OTCQX: GPHOF) ("Graphite One" or the "Company") is pleased to announce it has completed the 2022 Field Program at its 100%-owned Graphite Creek Project in Alaska. The 2022 Field Program included infill and step-out core drilling in the resource area. Additional core and sonic drilling were completed for geotechnical data collection at the proposed mill site, planned dry tailings/waste rock storage areas and the access route.

A total of 2,090 meters were drilled during the 2022 Field Program, including infill drilling and exploration drilling on the geophysical anomaly. Core drilling in the deposit area continued to encounter visible graphitic mineralization over wide intervals consistent with previous drilling results as reported in 2021 and as detailed in the press release of August 29, 2022 regarding Graphite One's 2022 Pre-Feasibility Study ("PFS"), which will be incorporated in a National Instrument 43-101 technical report posted at the Company's website and filed on SEDAR under the Company's profile at www.sedar.com on October 13, 2022.

"With only 7% of our 16 km geophysical anomaly incorporated in the PFS, which shows a pre-tax NPV of US$1.9 billion, our 2022 Field Program gives us confidence the Graphite Creek Project is truly a generational strategic resource," said Anthony Huston, CEO of Graphite One. "It is anticipated that the 2022 summer drilling program data will be incorporated when the Company is in a position to file a feasibility study to advance Graphite Creek during this critical time of under supply for U.S. strategic materials such as graphite."

The drill results for the 2022 Field Program will be released when data analysis is completed.

The 2022 Field Program activities included:

• Completion of geotechnical drilling on the proposed access route
• Ongoing Baseline environmental studies including:
• Raptor surveys
• Freshwater fishery surveys
• Imuruk Basin water quality and Basin fishery surveys
• Stream flow surveys
• Pit water quality testing
• Waste/Ore Humidity Cell testing
• Installation of weather stations
• Increasing the Graphite Creek field camp capacity from 24 to 60 persons

In addition, Graphite One representatives conducted community engagement meetings and subsistence advisory committee meetings.

Mr. Robert Retherford, P.Geo. with Alaska Earth Sciences, provided technical review for the 2022 Field Program. Mr. Retherford is a Qualified Person as defined under NI 43-101 and has reviewed and approved the technical content of this release.

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 near Nome, Alaska. The Graphite One project plan is anticipated to include an advanced graphite material and battery anode manufacturing plant expected to be sited in Washington State. The plan also includes a recycling facility to reclaim graphite and other battery materials, to be co-located at the Washington State site, the third link in Graphite One's circular economy strategy.

As announced on March 7, 2022 ¹, Graphite One's Graphite Creek resource in Alaska has been cited as the largest known graphite deposit in the United States by the U.S. Geological Survey (USGS) in its updated U.S. Mineral Deposit Database (USMIN).

The USGS report confirms Alaska Governor Mike Dunleavy's statement in support of Graphite One's designation as a U.S. government high-priority infrastructure project, stating, "Graphite Creek is the largest deposit of graphite in the nation and would be a superior domestic supply of this critical mineral.

Graphite One Inc. (GPH: TSX?V; GPHOF: OTCQX) is focused on developing its Graphite One Project (the "Project"), aimed at making the Company the dominant American producer of high-grade battery anode materials integrated with a domestic graphite resource. The Project is envisioned as a vertically integrated enterprise to mine, process, manufacture and recycle high grade anode materials primarily for the lithium-ion electric vehicle battery market. Graphite mined from the Company's Graphite Creek Property, located on the Seward Peninsula about 60 kilometers north of Nome, Alaska (the "Property"), would be processed into concentrate at an adjacent plant. The concentrate and other materials would be transformed into graphite anode materials and other value added graphite products at the Company's proposed advanced graphite materials manufacturing facility to be located in Washington State. The Company intends to make a production decision on the Project upon completion of a Feasibility Study.
