March 27, 2025 – Vancouver, British Columbia – Graphite One Inc. (TSX‐V: GPH; OTCQX: GPHOF) (“Graphite One”, “G1” or the “Company”), is pleased to announce updated mineral resource and reserve estimates for its Graphite Creek Project. Graphite One will file a feasibility study (“FS”) prepared in accordance with National Instrument 43-101 (“NI 43-101”) under the Company’s profile on SEDAR+ at www.sedarplus.ca within 45 days of the date of this news release, anticipated 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,” said 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.”
