• New Plan Indicates Reduced GHG Emissions, Improved Sustainability and Enhanced Expansion Potential
• Move Supports Northern's Strategy to be a Competitive Supplier to Battery Anode Material ("BAM") Markets

Ottawa, Ontario--(Newsfile Corp. - August 28, 2023) - Northern Graphite Corporation (TSXV: NGC) (OTCQB: NGPHF) (FSE: 0NG) (XSTU: 0NG) (the "Company" or "Northern) is pleased to announce the results of a new preliminary economic assessment ("PEA") that evaluated moving the processing plant for its Namibian operations located at Okorusu to the Okanjande mine rather than rehabilitating the mill in its current location.

The PEA indicates that economics remain attractive under the new plan, with higher capital costs but lower operating costs. In addition, greenhouse gas ("GHG") emissions are reduced, sustainability is improved, and the expansion potential of the project is substantially enhanced.

The PEA, issued July 31, 2023, was prepared by CREO Engineering Solutions and confirms the viability of moving milling operations directly to the Okanjande mine site, which eliminates the cost of trucking mineralized material 70km to Okorusu. This allows for a more sustainable operation that also includes the use of solar power and lower water consumption.

"Moving the mill also provides room for potential future expansion from the perspective of both processing and tailings capacity, which is something we do not have at the current location," said Northern Chief Operating Officer Kirsty Liddicoat. "The new approach also incorporates dry tailings into an integrated waste landform which means less water use and a more sustainable operation in support of the green transition," she added.

The Company is also looking at other ways to reduce its carbon footprint after the plant move, including the use of electric pit equipment and purchasing biofuel offsets on shipping concentrates from Namibia. The Okanjande/Okorusu operation is currently on care and maintenance and the goal remains to restart production in late 2024, subject to financing.

The Okanjande graphite mine is a key catalyst in Northern's strategy to become an integrated and sustainable mine-to-battery company, supplying markets in North America and Europe as they embrace the energy transition and widescale electrification. Graphite from Okanjande will also supply traditional markets, from refractory bricks for steelmaking, to heat management in consumer electronics, to friction and lubrication products for the global automobile industry.

"This PEA supports our strategy to develop Okanjande as a competitive asset that can be available to meet the demands of our customers in years to come," said Northern Chief Executive Officer Hugues Jacquemin. "Our new mining plan at Okanjande will allow us to move quickly to serve the fast-growing market for battery anode materials and increase our ability to expand the facilities over time."

The Okanjande deposit hosts a weathered resource of 5.9Mt containing 248kt of graphite in the measured and indicated category and 0.5Mt of inferred resources containing 17kt graphite, a transitional resource of 1.2Mt containing 53kt of graphite in the measured and indicated categories and 0.1Mt of inferred resources containing 2kt of graphite (@2.6% TCG cut-off grade and $1,250/t graphite price for weathered and transitional) and a fresh rock resource of 24.2Mt containing 1.3Mt of graphite in the measured and indicated categories and 7.2Mt of inferred resources with 0.4Mt of contained graphite (@3.1%TGC cut-off grade and $1,250/t graphite price). The PEA is based on only processing 6.1MT of measured and indicated resources (.34Mt of contained graphite), producing an average of 31,000 tonnes per year of concentrate over a 10-year mine life.

"The substantial measured and indicated hard rock resource at Okanjande, which is not yet closed off by drilling, presents a clear opportunity to substantially increase production in the future and the Company intends to complete additional work and prepare a new PEA with respect to an expansion scenario," said Ms. Liddicoat.

"The ability to add 31,000tpy of production at a very reasonable capital cost creates a compelling case for the development of Okanjande," said Mr. Jacquemin. "Okanjande has a very large resource located in one of the most politically stable countries in Africa, with easy access to a deep-water port which provides substantial competitive advantages over most other African projects."

Mineral resources that are not mineral reserves do not have demonstrated economic viability. While the PEA does not include inferred resources, the PEA is preliminary in nature and there is no certainty that the results of the PEA will be realized.
