VANCOUVER, March 20, 2024 - Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) ("Graphite One", "G1" or the "Company"), planning a complete domestic U.S. supply chain for advanced graphite materials, announced today that its wholly owned subsidiary, Graphite One (Alaska), Inc. ("G1 AK") has selected Ohio's "Voltage Valley" as the site of the Company's graphite anode manufacturing plant by entering into a land lease agreement for a 50 year term and an option to purchase (the "Land Lease"), as more fully described herein.

The site, located in Niles, Ohio, is a brownfield site previously used for storage of national defense stockpile critical minerals by the U.S. government, and has been processed through Ohio's Environmental Protection Agency (EPA) Voluntary Action Program. The site is located in the heart of the automobile industry, in an area with ample low-cost electricity produced from renewable energy sources. It is accessible by road and rail, with nearby barging facilities. The site's existing power lines are sufficient for Graphite One's Phase 1 production target of 25,000 tons per year ("tpy") of battery-ready anode material, and land is available for follow-on phases to ramp to 100,000 tpy of production. Water supply is also sufficient to support expanded operations.

It is anticipated that G1 AK's Ohio facility will manufacture synthetic graphite anode active materials. Production of natural graphite anode active materials will be added as soon as feedstock from G1 AK's Graphite Creek Project near Nome, Alaska is available.

"Graphite One is delighted to announce that, subject to financing, we will be building our advanced graphite material processing plant in northeast Ohio as the region emerges as a major electric vehicle hub. On a historical note, it's great to come full circle, this site also known as the old Warren Depot included graphite in the National Defense Stockpile more than 30 years ago, the last time the U.S. actually mined graphite," said Anthony Huston, President and CEO of G1. "Ohio is the perfect home for the second link in our strategy to build a 100% U.S.-based advanced graphite supply chain - from mining to refining to recycling. The U.S, simply cannot maintain a 21^st Century tech-driven economy without Critical Minerals like graphite."

While the Phase 1, 25,000 tpy facility's initial capital cost is estimated at approximately $435 million and is expected to employ more than 160 local residents, it is anticipated that the Warren Depot site can accommodate expansion to a 100,000 tpy facility. The Company is currently considering various project financing options.

"With manufacturing being one of Ohio's largest economic drivers, I am proud to see this new U.S.-based advanced graphite supply chain in Niles," said Congressman Dave Joyce. "This new project will bring over 160 jobs and spur even more economic growth in the area. I look forward to seeing the success of this project right here in OH-14."

The significant terms of the Land Lease are as follows:

• Lease term is 50 years with an option to purchase
• Rent escalation begins in the fifth year
• Construction is to commence within thirty-six (36) months, subject to financing
• 5-year right-of-first-refusal to lease or acquire up to thirty (30) contiguous acres
• Customary termination provisions

Graphite One announces that Anthony Huston, President & CEO of G1 is scheduled to present at the 2024 Kinvestor Critical Minerals & Mining Virtual Conference on Tuesday, March 26, 2024 at 9:00 am PT (12:00 pm ET).

Kinvestor Critical Minerals & Mining 2024 is a virtual conference featuring a stellar lineup of presenting companies in the critical minerals and mining industries. This event will showcase several junior mining companies exploring for minerals that are critical to the global energy transition including copper, graphite, titanium, and uranium, as well as the precious metals gold and silver. Presenting companies and industry experts will have the opportunity to share about latest developments and answer thoughtful questions from attendees.

The Options have an exercise price of $0.93 per share, being the closing price of the Company's shares on the TSX Venture Exchange ("TSX-V") on March 18, 2024. The Options vest one-third (1/3) on each of the first, second and third anniversary dates from the date of grant and will expire on March 19, 2029.

Each RSU and PSU will convert into one common share of the Company on each vest date. RSUs granted to management totaling 1,215,778 will vest one-third (1/3) on the first, second, and third anniversary dates from the date of grant and one-quarter (1/4) of the 1,161,178 RSUs granted to directors will vest on March 19, 2025, March 31, 2025, June 30, 2025 and September 30, 2025.

With the United States currently 100 percent import dependent for natural graphite, Graphite One is developing a complete U.S.-based, advanced graphite supply chain solution anchored by the Graphite Creek deposit, recognized by the US Geological Survey as the largest graphite deposit in the U.S. "and among the largest in the world." The Graphite One project plan includes an advanced graphite material and battery anode manufacturing plant located in Warren, Ohio. The plan also includes a recycling facility to reclaim graphite and the other battery materials, to be co-located at the Ohio site, the third link in Graphite One's circular economy strategy.

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 located in northeastern Ohio. The Company intends to make a production decision on the Project upon the completion of a Feasibility Study.
