What is the current status of these results?

Graphite One described the results as preliminary. Garnet grains were mechanically separated from crushed drill core samples at the University of Alaska Fairbanks, and the separated garnet fraction was analysed for REE concentration at ActLabs. The source does not state that commercial extraction has been demonstrated.

What does the testing indicate about the distribution of Rare Earths?

The company said bulk rock geochemical analyses indicate that Graphite Creek hosts an increased proportion of magnet REEs and HREEs relative to LREEs. It said garnets appear to be the reason for the relative abundance of HREEs, and that the garnets have two- to six-times higher REE concentration than the remainder of the ore rock when separated into garnet and other material.

What are Graphite One's stated next steps for the Rare Earths?

Graphite One plans to work with a U.S. National Lab to develop a testing plan to determine the best method for extracting REEs from the Graphite Creek garnets. The company is planning a 2026 REE testing programme. The source does not state that a particular extraction method has been selected or that extraction will occur.

Could the Rare Earths be recovered alongside graphite production?

Graphite One said the drill core samples came from the anticipated pit outlined in its Feasibility Study completed in February 2025, suggesting that REE recovery could potentially proceed alongside graphite extraction in the early years of mining operations. The company cautioned that there is no certainty that Rare Earths will be extracted from the Project or that any extraction would be economically feasible.

What wider project plans does the release describe?

Graphite One describes the Graphite One Project as a proposed vertically integrated enterprise to mine and process natural graphite and manufacture artificial and natural graphite anode active materials primarily for lithium–ion electric vehicle battery and energy storage markets. Its supply chain strategy involves transporting material to the lower 48 via the Port of Nome to an anticipated advanced graphite material and battery anode material manufacturing plant in Warren, Ohio, subject to project financing. The plan also includes a potential recycling facility at the Ohio site. The source cautions that the processing plant, graphite manufacturing plant and battery materials recycling facility may never be built.

Which company and securities listings are identified in the release?

The issuer is Graphite One Inc., identified in the source as listed on the TSXV: GPH and OTCQX: GPHOF. The release refers to the company as Graphite One, G1 or the Company.

What risks and uncertainties does the release identify?

Graphite One said the results and other statements concerning the quantity, quality and ability to economically extract Rare Earths, permitting, future production, processing and manufacturing plants and recycling facilities are forward-looking statements. It said tests may not be successful or result in successful products, and identified risks including market prices, exploration and exploitation results, continuity of mineralisation, obtaining permits, licences and title, third-party opposition, changes in government policies, availability of capital and financing, and general economic, market or business conditions.

Announcement Summary

Graphite One Inc. (TSXV: GPH) (OTCQX: GPHOF) announced independent testing found Rare Earths, including Magnet and Heavy Rare Earths, in Graphite Creek garnet material.

At UAF, garnet grains were mechanically separated from crushed drill core; ActLabs analyzed nine 1 m interval samples.
The release reported 14 Magnet or Heavy Rare Earths; 85% of REEs in garnet material were Magnet or HREEs.
Dysprosium in garnets ranged from 32-63 ppm, Yttrium from 198-427 ppm, and Scandium from 84 to 141 ppm.
Samples came from the anticipated pit outlined in G1's February 2025 Feasibility Study.
G1 plans to work with a U.S. National Lab in 2026 to develop a testing plan for extracting REEs from Graphite Creek garnets.
The company said results are preliminary, and REE recovery could potentially proceed alongside graphite extraction in early mining operations.

The company cautioned that REEs may not be extracted, extraction may not be economically feasible, and testing may not produce successful products. There is no certainty that the processing plant, graphite manufacturing plant, or battery materials recycling facility will be built; the Ohio manufacturing plant is subject to project financing.

Investor FAQs

Graphite One said independent analysis by Activation Laboratory (ActLabs) of Ancaster, Canada confirmed the presence of Rare Earths in Graphite Creek garnet material, with elevated levels of magnet and Heavy Rare Earths (HREE). The company said 85% of the REEs in the garnet material are magnet or HREEs. Dysprosium ranged from 32-63 ppm, Yttrium from 198-427 ppm and Scandium from 84 to 141 ppm in the garnets.
