Graphite One Advances U.S. Supply Vision
Collects Data for Alaska Mine, Battery-Grade Graphite Plant
After raising C$10 million earlier this year, Graphite One Inc. is collecting the final bits of data needed for a prefeasibility study that details the company’s vision to establish a United States supply chain for the coated spherical graphite used as an anode material in the lithium-ion batteries that power electric vehicles and store intermittent renewable energy. The first segment of this supply chain is the world-class Graphite Creek mine project about 35 miles north of Nome, the famed gold mining town in western Alaska. According to the most recent calculation, the Graphite Creek deposit hosts 10.95 million metric tons of measured and indicated resources averaging 7.8% (850,534 metric tons) graphitic carbon; and 91.89 million metric tons of inferred resource averaging 8% (7.34 million metric tons) graphitic carbon. As large as these resources outlined with drilling are, they only represent a small fraction of the thick lenses of graphite surfacing along an 11-mile-long stretch of the Kigluaik Mountains running across the Graphite Creek property. The second and perhaps most important segment of the Graphite One supply chain is a processing facility capable
mine at the Graphite Creek project in Alaska. A program scheduled to begin in July is expected to include 3,000 meters of infill drilling to upgrade a portion of the inferred resource to the higher confidence measured and indicated categories, as well as prepare to elevate these world-class resources to reserves with the completion of the PFS before the end of the year. In preparation for this PFS and a feasibility study to follow, this summer’s field work will also include geotechnical drilling at the proposed open pit mine and supporting infrastructure sites, as well as engineering and environmental baseline studies. “The 2021 drilling program will provide the additional information required to continue advancing the design and engineering for the proposed mine, the flotation process facility, the secondary treatment plant for producing coated spherical graphite and other graphite products, and all associated infrastructure,” said Stan Foo, chief operating officer of Graphite One (Alaska), a subsidiary developing Graphite Creek. “These investigations will allow Graphite One to firm up our understanding of the project as we unlock the full value of this unique large-flake graphite deposit.”
TEMSCO “With the growing demand for graphite in electric vehicle batteries and other energy storage applications — and recent actions by the Biden administration to secure U.S. supply chains for critical minerals — we see Graphite One’s aim to produce a U.S.-based supply chain solution becoming increasingly significant as a new potential source of advanced graphite products for decades to come,” said Huston. — Shane Lasley, North of 60 Mining News The company is seeking to unlock Graphite Creek’s value at a time when the global transition to electric vehicles and renewable energy is demanding massive quantities of the graphite that is found in abundance at the western Alaska project. The World Bank forecasts that low-carbon energy technologies, primarily lithium-ion batteries, will require 4.5 million metric tons of graphite per year by 2050, which is nearly a 500% increase over 2018 levels and a 310% increase over the total graphite mined worldwide during 2020. And there are currently no domestic graphite mines to help supply the United States’ share of this skyrocketing demand.
of upgrading Graphite Creek concentrates into the anode material that goes into lithium-ion batteries and other industrial graphite products. A 2017 preliminary economic assessment that offered a first glimpse of what this supply chain might look like investigated the economic and engineering parameters of a mine at Graphite Creek that would produce roughly 60,000 metric tons of 95% graphite concentrate per year and a processing facility to upgrade these annual concentrates into 41,850 metric tons of the coated spherical graphite and 13,500 metric tons of purified graphite powders annually. A PFS slated for completion by the end of this year will provide a more detailed and definitive look at this potential North American supply of the graphite demanded by a transition to e-mobility plugged into power grids increasingly energized by renewable electricity. “While the 2017 preliminary economic analysis indicated excellent economics, we are very excited about the potential for the PFS to show a clear path for further development,” said Graphite One President and CEO Anthony Huston. Much of Graphite One’s 2021 fieldwork will focus on collecting the data needed for designing and permitting a
