Graphite One's domestic supply chain strategy

With the United States currently 100 per cent import dependent for natural graphite, Graphite One is developing a complete United States-based, advanced graphite supply chain solution anchored by the Graphite Creek deposit, recognized by the U.S. Geological Survey as the largest graphite deposit in the U.S. "and among the largest in the world." The Graphite One project supply chain strategy involves transporting material to the lower 48 through the Port of Nome to an anticipated advanced graphite material and battery anode material manufacturing plant to be located in Warren, Ohio, subject to project financing. The plan also includes a potential recycling facility to reclaim graphite and the other battery materials, to be co-located at the Ohio site, the third link in Graphite One's circular economy strategy.

The project is proposed as a vertically integrated enterprise to mine and process natural graphite and to manufacture artificial and natural graphite anode active materials primarily for the lithium-ion electric vehicle battery and energy storage markets.
