Graphite One Inc. (TSX-V: GPH; OTCQX: GPHOF) Building 'America’s First Fully Integrated Graphite Supply Chain’

Highlights

• Graphite One aims to supply high-grade anode materials for EV batteries and energy storage systems through a fully integrated mine-to-market strategy.
• The Graphite One Project would enhance North America’s graphite supply chain with high-purity coated spherical graphite (CSG).
• The 2024 Feasibility Study confirmed a major resource expansion, positioning Graphite Creek as one of the world’s largest graphite deposits.
• The company has achieved significant funding milestones to advance its integrated U.S. graphite supply chain strategy.

Graphite is the largest component in lithium-ion batteries, yet the U.S. imports 100% of its supply. With EV adoption and energy storage demand accelerating, securing a domestic source is critical. Graphite One (TSX-V: GPH) (OTCQX:GPHOF) highlights that it is closing that gap by building 'America’s first fully integrated graphite supply chain’.

Strategic Highlights

• Largest U.S. Graphite Resource
  2024 Feasibility Study confirmed a tripling of reserves:
• Measured + Indicated: 104.7 Mt @ 4.6% Cg
• Proven & Probable Reserves: 71.2 Mt @ 5.2% Cg
  Recognized by USGS as the largest natural graphite deposit in the U.S.
• Vertically Integrated Model
  From Graphite Creek Mine in Alaska to downstream processing in Ohio, producing 100,000 tpy of high-grade anode material for EV batteries and energy storage systems.
• Economics Metrics
• Pre-tax NPV: $6.4B | IRR: 30% | Payback: 7.3 years
• Post-tax NPV: $5.0B | IRR: 27%
  Based on 175,000 tpy graphite concentrate and 20-year mine life.
• Government & Strategic Support
• $37.5M Defense Production Act funding
• EXIM Bank LOIs totaling $895M for mine and manufacturing facility
• Direct investment from three Alaska Native Regional Corporations
• FAST-41 designation for streamlined permitting.

Why it Matters?

Global graphite demand is surging, driven by EVs and energy storage. Graphite One offers a secure, domestic solution backed by federal support, project economics, and strategic partnerships.

Graphite One aims to supply high-grade anode materials for EV batteries, energy storage systems and defence applications through a fully integrated mine-to-market strategy for the rapidly growing lithium-ion battery and storage markets.  The company plans to combine annual 175,000 tpy natural graphite concentrate production at its Graphite Creek Mine in Alaska with downstream processing in Warren, Ohio, where a manufacturing facility is envisioned, subject to financing, to produce 100,000 tpy of commercial-scale lithium-ion battery anode materials and other graphite products for the U.S. domestic market.

Graphite Creek Resource Expansion

Located approximately 60 kilometers north of Nome on Alaska’s Seward Peninsula, the Graphite Creek Property underwent a major resource update in its 2024 Feasibility Study. Using a 2% Cg cutoff and incorporating drilling data through 2024, the updated Mineral Resource Estimate tripled from the resource disclosed in the pre-feasibility study (PFS)as follows:

Recognized by the U.S. Geological Survey in 2022 as the largest natural graphite deposit in the U.S. and among the world’s largest in 2023, the Graphite Creek resource continues to gain importance amid surging global demand for graphite, a key material in the energy transition.

Bankable Feasibility Study

With the support from the Department of Defense’s $37.5 million Defense Production Act Title III funding, completed the feasibility study 15 months ahead of schedule and tripling the size of the resource. 

Feasibility Study financial highlights, based on an 8% discount: a pre-tax NPV $6.4 billion, 30% IRR and a payback of 7.3 years.  On a post-tax basis, NPV $5.0 billion, 27% IRR and a payback of 7.5 years.  The results was modelled based on annual graphite concentrate production capacity of the Graphite Creek Mine increased from 53,000 tpy to 175,000 tpy while maintaining a 20-year mine life and 100,000 tpy of anode material production.

Funding Boost Paves Way for U.S. Graphite Push

Over the past three months, Graphite One has achieved significant funding milestones to advance its integrated U.S. graphite supply chain strategy.

• In October, the company closed a $5.0 million (CDN$7.0 million) strategic investment from two Alaska Native corporations Doyon Limited and Aleut, through a non-brokered private placement of 8,514,024 units at CDN$0.82 per unit.
• Earlier, in September, the S. Export-Import Bank (EXIM) extended a non-binding Letter of Interest for up to $570 million to support the development of the Graphite Creek mine in Alaska, adding to a $325 million LOI announced in October 2024 for its planned AAM Ohio facility—bringing total EXIM support to $895 million.
• Additionally, in August, Graphite One closed a CDN$13.3 million brokered private placement, further strengthening its project development funding base.

With growing U.S. government support and recent strategic funding from Alaska Native corporations and EXIM Bank, Graphite One is advancing a fully integrated mine-to-market model to produce high-grade anode materials for electric vehicles and energy storage systems, reinforcing its role in the global energy transition.
