With help of DOD investment Graphite One has finished the 2023 and 2024 drilling methods that expanded the leisurely and indicated useful resource and confirmed and possible store

Newsletter of a NI 43-101 compliant Feasibility Find out about might be filed in April 2025 — and is expected to triple the manufacturing price disclosed in Graphite One’s 2022 pre-feasibility file (the “PFS”)

Confirmed/Possible Mineral Retain tonnage is 317% of the PFS store estimate.  The corresponding contained graphite is 296% of the PFS estimate

Graphite Creek is now triple the dimensions it used to be when USGS simply 3 years in the past deemed it “the largest flake graphite deposit in the U.S.”

VANCOUVER, BC, March 27, 2025 /PRNewswire/ – Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) (“Graphite One”, “G1” or the “Company”), is happy to announce up to date mineral useful resource and store estimates for its Graphite Creek Venture. Graphite One will record a feasibility find out about (“FS”) ready according to Nationwide Software 43-101 (“NI 43-101“) below the Corporate’s profile on SEDAR+ at www.sedarplus.ca inside 45 days of the presen of this information leave, expected to be filed in April 2025.

“With grant support under the Defense Production Act Title III authorities, Graphite One was able not only to accelerate completion of our feasibility study by 15 months, but also quadrupled our planned drilling program, producing the results we announce today,” mentioned Anthony Huston, CEO of Graphite One. “We will now enter the permitting process with a production rate triple what we projected just over two years ago.  The Proven and Probable Mineral Reserve tonnage is 317% of the PFS reserve estimate and the corresponding contained graphite is 296% of the PFS estimate.  All of this is based on results from just 1.2 miles of the total 9.5 mile long geophysical anomaly.”

Graphite One’s announcement these days follows the newsletter utmost generation of President Trump’s Govt Sequence (“EO“), “Speedy Measures to Building up American Mineral Manufacturing. Graphite One’s press leave at the EO may also be discovered at this link.

“With President Trump’s new Executive Order, G1 is working with Congress, the Administration, and federal agencies to accelerate our Graphite One supply chain project through permitting and into production, to end the nation’s 100% import dependency for graphite,” Mr. Huston added. “With these new results, Graphite Creek is now triple the size when the US Geological Survey reported just three years ago that Graphite Creek was the largest flake graphite deposit in the U.Sⁱ“.

Mineral Useful resource and Reserves

The Graphite Creek quality (the “Property“) is situated at the Seward Peninsula, Alaska about 38 miles (60 km) north of Nome.  The Detail accommodates 23,680 acres (9,600 hectares) of Climate of Alaska mining claims.  The declare stop is composed of 176 claims, of which 163 are fully owned by way of Graphite One (Alaska) Inc. and 13 are rented to Graphite One (Alaska) Inc.  G1’s storage is completely on Climate land.  The graphite mineral zone is uncovered at the floor and moves East/Northeast alongside the North Face of the Kigluaik Mountains.  The Feasibility Find out about Pit and Mineral Retain footprint represents simply 1.2 miles (1.9 km) of the 9.5 miles (15.3 km) lengthy electromagnetic anomaly (Determine 1).

Via 2022, 2023 and 2024, 90 holes were drilled within the useful resource section for a complete of 13,482 meters of drilling.  The useful resource database is composed of twenty-two,806 assays.  The useful resource rest distinguishable ill dip, and alongside crash to the East and West. 

The Mineral Useful resource Estimate for Graphite Creek used to be up to date with knowledge throughout the 2024 drilling program. The method old used to be the similar as that described within the PFS.  A decrease cut-off grade of two% used to be old for the 2022 and 2024 useful resource.  The FS mineral useful resource estimate is gifted in Desk 1.

The 2023-2024 drilling program enthusiastic about changing Inferred Sources into Steady and Indicated, to permit annual graphite manufacturing to be higher within the FS.  A comparability of the PFS and FS mineral sources may also be revealed in Desk 2.

The 2024 Mineral Retain is composed of 71.219 million tonnes of Confirmed and Possible subject material at a median diluted grade of five.22% graphite, submit 3.7 million tonnes of contained graphite. A variable abridge_–off grade between 2%-3% used to be old in calculating the confirmed/possible store.  Desk 3 displays the mineral store.

The FS Mineral Retain estimate tonnage is 317% of the PFS store estimate and the contained graphite is 296% of the PFS estimate.  A comparability of the PFS as opposed to FS mineral store may also be revealed in Desk 4.

Graphite One’s Home Provide Chain Technique

With the US virtually 100% import dependent for anode lively fabrics, Graphite One is creating a whole U.S.-based, complicated graphite provide chain answer anchored by way of the Graphite Creek storage, identified by way of the USA Geological Survey as the most important graphite storage within the U.S. “and among the largest in the world.” The Graphite One Venture plan contains a sophisticated graphite subject material and battery anode subject material production plant situated in Warren, Ohio. The plan additionally features a recycling facility to reclaim graphite and the alternative battery fabrics, to be co-located on the Ohio web page, the 3rd hyperlink in Graphite One’s round financial system technique. The construction of those amenities rest matter to financing.

About Graphite One Inc.

GRAPHITE ONE INC. continues to manufacture its Graphite One Venture (the “Project“) to develop into an American manufacturer of high-grade anode fabrics this is built-in with a home graphite useful resource.  The Venture is proposed as a vertically built-in endeavor to mine, procedure and create anode lively fabrics essentially for the lithium‐ion electrical automobile battery marketplace.  As eager forth within the Corporate’s 2022 Pre-Feasibility Find out about, graphite mineralization mined from the Corporate’s Graphite Creek Detail, positioned at the Seward Peninsula about 60 kilometers north of Nome, Alaska, could be processed into listen at an adjoining processing plant.  Herbal and synthetic graphite anode lively fabrics and alternative worth‐added graphite merchandise could be fabricated from the listen and alternative fabrics at Graphite One’s proposed complicated graphite fabrics production facility to be situated in northeastern Ohio.
