What are the updated Proven and Probable Mineral Reserve figures?

The 2024 Mineral Reserve is stated as 71.219 million tonnes of Proven and Probable material at an average diluted grade of 5.22% graphite, yielding 3.7 million tonnes of contained graphite. The company states that the reserve tonnage is 317% of the 2022 pre-feasibility study reserve estimate and that contained graphite is 296% of that estimate.

What drilling and resource information supports the update?

Through 2022, 2023 and 2024, 90 holes were drilled in the resource area for a total of 13,482 meters of drilling, with a resource database comprising 22,806 assays. The feasibility study pit and Mineral Reserve footprint covers 1.2 miles (1.9 km) of the 9.5 miles (15.3 km) long electromagnetic anomaly. The resource remains open down dip and along strike to the East and West.

What qualifications apply to the mineral resource estimates?

The source states that Mineral Resources are inclusive of Mineral Reserves, but that Mineral Resources which are not Mineral Reserves have not demonstrated economic viability. It also states that there is no certainty that any part of a Mineral Resource will ever be converted into Reserves. Inferred Mineral Resources are described as too speculative to be included in economic evaluations, and additional trenching and/or drilling would be required to convert them to Indicated or Measured Mineral Resources.

What assumptions and limitations are attached to the Mineral Reserve estimate?

The Mineral Reserve estimate uses a variable cut-off grade of 2.0% Cg – 3.0% Cg, a net average Graphite Price of US$1,200/t including transport and treatment charges, a 3.5% - 8.0% royalty and a mill recovery of 90%. The source states that the final pit design contains an additional 7.6 Mt of Measured and Indicated resources treated as waste in the final mine production schedule, and 40.4 Mt of Inferred resources above the economic cut-off grade. It also states that there is no certainty that any part of the Inferred Resources could be converted into Mineral Reserves.

What is the status of the proposed US-based supply chain facilities?

The Project plan includes a graphite material and battery anode material manufacturing plant in Warren, Ohio, as well as a recycling facility intended to be co-located at the Ohio site. The source states that the building of these facilities remains subject to financing. The source also identifies uncertainties related to obtaining necessary permits, licences and title, delays due to third-party opposition, continued availability of capital and financing, market prices, exploitation and exploration successes, and continuity of mineralisation.

What does the company say about the Executive Order and future production?

The CEO said Graphite One would enter the permitting process with a production rate triple what the company projected in its 2022 pre-feasibility report, and said the company was working with Congress, the Administration and federal agencies to accelerate the project. However, the company cautions that there is no certainty that the Executive Order will affect it as described. The release also states that forward-looking statements are not guarantees of future performance and that actual results or developments may differ materially.

Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) announced updated mineral resource and reserve estimates for its Graphite Creek Project.

With DOD funding support, Graphite One completed its 2023 and 2024 drilling programs; 90 holes were drilled through 2022, 2023 and 2024.
Graphite One will file an NI 43-101-compliant Feasibility Study on SEDAR+ within 45 days of March 27, 2025, anticipated in April 2025.
The 2024 Mineral Reserve consists of 71.219 million tonnes of Proven and Probable material at an average diluted grade of 5.22% graphite.
The reserve estimate includes 3.7 million tonnes of contained graphite; the release states 317% of the PFS reserve tonnage and 296% of contained graphite.
Reserve calculations use a variable cut-off grade between 2%-3%, a net average Graphite Price of US$1,200/t, and a 3.5% - 8.0% royalty.
The planned Ohio advanced graphite materials manufacturing and recycling facilities remain subject to financing.

The company said it will enter the permitting process with a production rate triple what it projected in its 2022 PFS. The estimate covers 1.2 miles of the total 9.5-mile geophysical anomaly.
