GRAPHITE ONE COMPLETES EXTENSIVE 2023 DRILLING CAMPAIGN AT GRAPHITE CREEK, REPORTS WIDE INTERCEPTS OF HIGH-GRADE GRAPHITE

Graphite One Inc. has completed its 2023 summer drilling program, marking the largest exploration program in the company's history and allowing the company to accelerate completion of its National Instrument 43-101 -- Standards of Disclosure for Mineral Projects (NI 43-101)-compliant feasibility study, anticipated to be released in the fourth quarter of 2024.

With the support of the grant funding awarded pursuant to the Department of Defense Technology Investment Agreement under Title III of the U.S. Defense Production Act (DPA), which is funded through the Inflation Reduction Act, Graphite One carried out a large-scale drilling program, quadrupling the number of feet drilled in 2023 compared with 2022.

As a result of this DPA grant and a strategic investment from Bering Straits Native Corp. (BSNC), Graphite One completed 57 holes for a total of 8,736 metres (28,661 feet) of drilling, including five geotechnical holes for the primary purpose of evaluating construction sites or hydrology conditions.

The remaining 52 resource holes all intersected visual graphite mineralization and continued to demonstrate exceptional consistency of a shallow, high-grade graphite deposit that remains open both to the east and west of the existing mineral resource estimate (MRE).

Two thousand twenty-three select drill holes with significant graphite mineralization include (see the table entitled "Summary of 2023 summer drilling program results"):

• 23GC088 returns 9.63 m of 13.19 per cent Cg (graphitic carbon) from 70.60 m;
• 23GC092 returns nine m of 14.89 per cent Cg from 35 m;
• 23GC099 returns 15.02 m of 10.75 per cent Cg from 20 m;
• 23GC102 returns 10.88 m of 11.14 per cent Cg from surface and 8.03 m of 10.56 per cent Cg from 66.14 m farther downhole.

"Our team's impressive effort put us well on the way to completing the feasibility study as expeditiously as possible," added Anthony Huston, founder and chief executive officer of Graphite One. "The results -- 52 graphite intercepts over 52 holes -- confirm our confidence that Graphite Creek is truly a generational resource of strategic value to the United States, and we wish to thank the Alaskan government, our funding partners, local stakeholders and communities for their continued support in advancing this critical asset."

Notable intercepts are listed herein. The company anticipates that the remaining assays will be received by the end of the year and incorporated into the Department of Defense DPA-supported feasibility study, which is anticipated to be released in the fourth quarter of 2024.

"I commend the Graphite One staff and our contractors for their exceptional execution of what was by far G1's most ambitious summer drilling program -- in terms of drill holes and feet drilled -- in the company's history," said Mike Schaffner, senior vice-president of mining for Graphite One. "The conversion to a ground-based drilling program was very successful, resulting in much improved performance compared to past years by eliminating weather-related delays and reducing the reliance on helicopter support."

"The leadership team at Bering Straits Native Corp. (BSNC) is pleased with the early returns from Graphite One's busy drilling season. The impressive work of the Graphite One team, which includes local BSNC shareholders, reinforces our decision to support the project," said Marleanna Hall, BSNC director of external affairs and public relations. "As a BSNC shareholder originally from Nome myself, I am thrilled by what this project can do for our region."

DPA grant

On July 17, 2023, Graphite One (Alaska) Inc., a wholly owned subsidiary of Graphite One, was awarded the DPA grant whereby the DPA's share of up to $37.5-million (U.S.) is contingent upon the company's obligation to raise an equivalent dollar-for-dollar amount. The total aggregate amount of up to approximately $75-million (U.S.) is subject to the terms of the DPA agreement. The financing objective pursuant to the DPA agreement is to perform an accelerated feasibility study to modernize and expand domestic production capacity and a domestic supply chain for graphite battery anodes for electric vehicles and alternative energy batteries. The term of the DPA agreement ends on Nov. 30, 2024, and, if funds then remain available for drawdown pursuant to the DPA grant, the company may request an extension to the term end date to complete the feasibility study, if required.

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 Graphite Creek 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.

Technical disclosure/qualified person

Rob Retherford, PGeo, with Alaska Earth Sciences Inc., provided oversight to the 2023 drilling and sampling program. Mr. Retherford is a qualified person as defined under National Instrument 43-101, and has reviewed and approved the technical content of this release.

Quality assurance/quality control (QA/QC) program applied

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 downhole directional surveys), core handling procedures (logging, sampling and 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.

About Graphite One Inc.

Graphite One continues to develop its Graphite One 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 prefeasibility study, graphite mineralization mined from the company's Graphite Creek property, situated on the Seward peninsula about 60 kilometres 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.
