Graphite One Engages Ames National Laboratory to Assess Rare Earth Recoveries from Alaska's Graphite Creek Deposit
Earlier garnet testing provides a basis for recovery research, while the broader graphite supply-chain strategy remains dependent on financing.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Graphite One (GPHOF) has engaged Ames National Laboratory for a three-month study of rare earth recovery from Alaska’s Graphite Creek deposit.
The company-funded project will begin immediately under a Strategic Partnership Project Agreement. It will test recovery from garnet material, including acid leaching, separation and purification, and develop a preliminary scalable processing plan assessing material balances, reagent use, water consumption and waste generation. Earlier testing in 2025 found that 85% of rare earth elements in tested garnet material were magnet or heavy rare earths. The separated garnet fraction had two to six times higher rare earth concentrations than the remaining material. The company’s broader domestic graphite supply-chain strategy remains subject to project financing.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

Three-month project with the Department of Energy Strategic Special Program will evaluate leaching, heavy and light rare earth separation, and a preliminary scalable process flowsheet
The work, conducted under a Strategic Partnership Project Agreement, will examine garnet preparation and characterization, acid leaching, separation of heavy rare earth elements ("HREEs") from light rare earth elements ("LREEs"), and product purification. Funded by G1. the program is intended to develop a preliminary scalable flowsheet and evaluate its mass balance, reagent use, water consumption and waste generation. The three-month project will commence immediately.
"Graphite Creek's garnets host rare earth elements, including the heavy rare earths and magnet metals that are critical to
Ames Lab G1 REE Work Plan
The Ames Lab program will begin with mineralogical and chemical characterization of the Graphite Creek garnet material, comminution and mechano-chemical activation, followed by preliminary acid-leaching tests. Subsequent work will optimize leaching conditions and screen separation approaches, including solvent extraction, stepwise pH adjustment and fractional crystallization. The final phase will assess precipitation and purification of REE group products and prepare an integrated flowsheet and mass balance.
Graphite Creek REE Potential
The Ames Lab program follows earlier work conducted in 2025 by Graphite One in which garnet grains were mechanically separated from crushed Graphite Creek drill-core samples at the University of Alaska Fairbanks and analyzed for REE concentrations by Activation Laboratories ("ACTLabs").
ACTLabs found that

Forward-Looking Statements
All statements in this release, other than statements of historical facts, including those related to the conduct and results of the research program with Ames Lab, the quantity and quality of and ability to economically extract the rare earth elements from the deposit, timing and completion of permitting, future production, establishment of a processing plant and a graphite manufacturing plant, establishment of a battery materials recycling facility, and events or developments that the Company intends, expects, plans, or proposes are forward-looking statements Generally, forward‐looking information can be identified by the use of forward‐looking terminology such as "proposes", "expects", "is expected", "scheduled", "estimates", "projects", "plans", "is planning", "intends", "assumes", "believes", "indicates", "to be" or variations of such words and phrases that state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved". The Company cautions that there is no certainty that rare earth elements will be extracted from the Project, that rare earth elements extracted will be economically feasible, that either the processing plant and graphite manufacturing plant or the battery materials recycling facility will ever be built, the tests of the Company's material will be successful or that such tests will result in the development of successful products.
