Graphite One Confirms the Presence of Rare Earth Elements at its Graphite Creek Deposit

 November 13, 2025 – Vancouver, British Columbia – Graphite One Inc. (TSX‐V: GPH; OTCQX: GPHOF) (“Graphite One”, “G1” or the “Company”) announced today that it has identified the presence of Rare Earth Elements (“REEs”) in its Graphite Creek deposit, north of Nome, Alaska.  Geochemical analyses completed by Activation Laboratories Ltd (“ActLabs”) found rare earths in drillcore samples of garnet-bearing ore rock within the anticipated pit outlined in G1’s Feasibility Study (“FS”), completed in February 2025.  Already recognized by the United States Geological Survey as the largest known natural graphite deposit in the U.S.[1], G1’s FS resource estimate tripled previous projections. The FS pit and it’s anticipated 20-year mine life comprises just 12% of the 15.3 km (9.5 mile) long graphite- and garnet-bearing mineralized zone.
