Graphite One Completes 2021 Field Program at

100% Owned Graphite Creek Deposit, Alaska

2021 Drilling Continues to Encounter Visible Graphitic Mineralization over Wide

Intersections from Surface

October 13, 2021 – Vancouver, British Columbia –Graphite One Inc. (GPH: TSX‐V;

GPHOF: OTCQX) (“Graphite One” or the “Company”) is pleased to announce that it has

completed the 2021 field program (“Field Program”) at its 100% owned Graphite Creek

project in Alaska. The Field Program included infill and step out core drilling in the

resource area and additional core and sonic drilling for geotechnical data collection in the

proposed mill site and dry tailings/waste rock storage areas. Other work included access

route engineering, surface water and groundwater hydrology studies, wetlands mapping

and aquatic life surveys.

A total of 2,052 meters were drilled during the 2021 program including 1,695 meters of HQ

core drilling and 357 meters of sonic drilling. Results from 8-hole core holes completed in

the resource area are expected to be released in Q1 2022 when data analysis is

completed. Additional core drilling was completed to collect detailed geotechnical

information for open pit and mills site engineering, and for groundwater investigations. The

5 sonic holes completed in the dry tailings/waste rock storage area will provide detailed

geotechnical information to advance the engineering of these facilities. The drill program

will generate additional information to update the resource model and provide technical

data for the project’s Feasibility Study (“FS”) expected to be initiated in 2022. The

Company’s Preliminary Feasibility Study (“PFS”) is progressing and scheduled for release

later this year.

2021 core drilling in the deposit area continued to encounter visible graphitic mineralization

over wide intervals consistent with previous drilling results as reported in 2019 and in the

2017 Preliminary Economic Assessment (“PEA”).

“With the recent CDN $21 million in funding, our efforts have progressed towards

completion of the PFS for the largest known and highest-grade graphite deposit in the

United States,” said Anthony Huston, CEO of Graphite One. “The 2021 Field Program also

initiated the drilling and additional data collection needed to begin work on the FS after the

PFS is completed. We are very pleased with the successful execution of the 2021 Field

Program, as historical drilling coupled with the new data clearly demonstrates the

predictability and consistency of high-grade, near surface graphite. With the concepts and

conclusions outlined in the PEA suggesting a 40-year mine life, the Graphite Creek deposit

continues to show potential to be an essential long-life component of the graphite supply

chain, one of four critical minerals that are on the US National Defense stockpile list. While

the PEA demonstrated the project’s economic viability, we expect these further studies with

their optimized plans for the mine and processing facilities to support improved economics.”

Mr. William Ellis, P. Geo, with Alaska Earth Sciences provided oversite to the 2021 drilling

and sampling program. Mr. Ellis is a Qualified Person as defined under NI 43-101 and has

reviewed and approved the technical content of this release. Strict protocols for quality

assurance and quality control were maintained through the sampling process and included

the insertion of standards and blanks in the sample stream.

About Graphite One Inc.

GRAPHITE ONE INC. (GPH: TSX‐V; GPHOF: OTCQB) continues to develop its Graphite

One Project (the “Project”), whereby the Company could potentially become an American

producer of high grade Coated Spherical Graphite (“CSG”) that is integrated with a

domestic graphite resource. The Project is proposed as a vertically integrated enterprise to

mine, process and manufacture high grade CSG primarily for the lithium ‐ion electric vehicle

battery market. As set forth in the Company’s Preliminary Economic Assessment, potential

graphite mineralization mined from the Company’s Graphite Creek Property, is expected to

be processed into concentrate at a graphite processing plant. The proposed processing

plant would be located on the Graphite Creek Property situated on the Seward Peninsula

about 60 kilometers north of Nome, Alaska. CSG and other value‐added graphite products,

would likely be manufactured from the concentrate at the Company’s proposed graphite

product manufacturing facility, the location of which is the subject of further study and

analysis. The Company intends to make a production decision on the Project once a

feasibility study is completed.
