Independent Testing Confirms Elevated Magnet and Heavy Rare Earth Presence at Graphite One’s Alaska Graphite Deposit

December 16, 2025 – Vancouver, British Columbia – Graphite One Inc. (TSXV: GPH; OTCQX: GPHOF) (“Graphite One”, “G1” or the “Company”) announced today that results from independent analysis of Graphite Creek garnet material confirm the presence of Rare Earths in the Graphite Creek deposit, with elevated levels of the magnet and Heavy Rare Earths (“HREE”).  The drill core samples were from the anticipated pit outlined in G1’s Feasibility Study (“FS”) completed in February 2025, suggesting that REE recovery could potentially proceed alongside graphite extraction in the early years of mining operations.
