R&D Grant to Develop Sustainable Battery

Anode Materials

Project designed to transform natural graphite processing by-products into high-

performance, battery-grade materials

Partners will integrate upstream feedstock control with downstream processing and

electrochemical testing

Goal is maximizing the yield from graphite mine concentrates while minimizing the waste

and carbon footprint

24-month initiative will position both companies to deliver a competitive Western supply

chain alternative for the energy storage market

Ottawa, Ontario--(Newsfile Corp. - November 3, 2025) - Northern Graphite Corporation

(TSXV: NGC)

(OTCQB: NGPHF) (FSE: 0NG) (XSTU: 0NG)

and Rain Carbon Canada Inc.

("

RAINCA

"), a wholly owned subsidiary of Rain Carbon Inc. ("

RAIN

"), are pleased to announce that their

consortium is receiving funding support up to C$860,000 (€530,000) under the Canada-Germany

Collaborative Industrial Research and Development Program.

The 24-month project will have a total cost of $2.2 million and will focus on transforming low-value natural

graphite fine fractions byproduct into high-performance, battery-grade anode material (BAM) and is

jointly supported through advisory services and funding from the

National Research Council of Canada

Industrial Research Assistance Program

(

NRC IRAP

) and Germany's Federal Ministry for Economic

Affairs and Energy (

BMWE

) through its Central Innovation Program for small and mid-size companies

(

ZIM

). Partners under the initiative - NGC Battery Materials GmbH (

NGCBM

), Northern's Germany-

based battery materials unit, and RAINCA - aim to increase milling and shaping yield by upcycling

byproduct fine fractions, reducing waste and minimizing the need for additional mining.

"With a shared goal of building a robust supply chain from mine-to-battery, this collaboration combines

the upstream strengths of our mining and graphite processing operations with RAIN's unmatched carbon

science expertise to deliver advanced solutions for a clean energy future," said Northern Chief Executive

Officer Hugues Jacquemin.

The project will leverage the strengths of both partners, with Northern supplying natural graphite

feedstock sourced from its operations in Canada and Namibia, and applying advanced sizing, shaping,

and purification techniques to produce highly uniform, battery-grade feedstock particles. RAIN will

contribute advanced conversion processes and its proprietary LIONCOAT® carbon coating technology,

while leading electrochemical performance testing to ensure the final materials meet the highest global

standards. The efforts will be anchored by RAIN's Technology Innovation Center for Energy Storage

Materials in Hamilton, Ontario, which houses a demonstration plant for material conversion and coating

at pilot-scale, an advanced analytical lab for evaluating the physicochemical properties of powder

materials, and an application lab dedicated to battery cell fabrication and performance assessment.

Northern is focused on becoming an integrated, mine-to-battery supplier of battery anode material, the

main component in lithium-ion batteries. To that end, in January 2024 the Company formed its Battery

Materials Group through the acquisition of the assets and R&D team of the battery division of Germany's

Heraeus Group which included a fully operational, state-of-the-art laboratory in Frankfurt. NGCBM is

leading the development of a vertically integrated supply chain for natural graphite-based BAMs,

leveraging Northern's existing mining operations in Canada and Namibia and downstream partnerships

across Europe and North America.

"This project aims to significantly reduce the carbon footprint per kilogram of battery material by

introducing processes that result in less waste from the milling cycle and utilize more of the graphite that

we mine," said Northern Chief Product Officer Dr. Moritz Hantel. "By improving the conversion rate of

flake graphite into battery anode material, we align with the principles of the circular economy, reducing

industrial waste and strengthening the consortium's leadership in the innovation of sustainable battery

materials."

For RAIN, the initiative acts as a strategic catalyst that accelerates product development, shortens time-

to-market cycles, and enhances the company's technical capabilities while sharpening its competitive

advantage in processing battery-grade carbon precursor materials under the LIONCOAT® brand.

"This partnership not only enhances RAIN's capabilities in processing battery-grade carbon precursor

materials but also enables NGCBM to expand its value chain beyond raw material extraction and

processing, advancing into the production of high-value battery materials," said RAIN President, Gerard

Sweeney. "Together, both organizations are well-positioned to meet the stringent quality standards of the

highly competitive energy storage market."

"Research and development are at the heart of building resilient and sustainable critical mineral supply

chains. Through the G7 Critical Minerals Action Plan, we are collaborating with trusted international

partners to advance innovative projects-like the work led by Northern Graphite and Rain Carbon

Canada-that reduce environmental impacts, maximize production, and strengthen Canada and our allies'

competitive edge," said the Honourable Tim Hodgson, Minister of Energy and Natural Resources.

"Research and development are the driving forces behind Canada's leadership in critical minerals.

Through strategic collaboration with international partners and innovative companies like Northern

Graphite and Rain Carbon Canada, we are accelerating breakthroughs across the supply chain-from

exploration to processing-ensuring our solutions are sustainable, competitive and globally impactful,"

added Claude Guay, Parliamentary Secretary to the Minister of Energy and Natural Resources.

About Northern Graphite

Northern is a Canadian, TSX Venture Exchange listed company that is the only flake graphite producing

company in North America.

Northern is focused on becoming a world leader in producing natural

graphite and upgrading it into high-value products critical to the green economy, including anode

material for lithium-ion batteries/EVs, fuel cells and graphene, as well as advanced industrial

technologies. The Company's mine-to-battery strategy is spearheaded by its Battery Materials Group,

which has a fully equipped, state-of-the-art laboratory in Frankfurt.

Northern's graphite assets include the producing Lac des Iles mine in Quebec, where the Company is

boosting output to meet growing demand from industrial customers and coming demand from North

American battery makers. The Company also owns the large-scale, advanced stage Bissett Creek

graphite project in Ontario and the fully permitted Okanjande graphite mine in Namibia, which is currently

on care and maintenance, and represents an opportunity to substantially increase graphite production at

a lower cost and with a shorter time to market than most competing projects. All projects have "battery

quality" graphite and are located close to infrastructure in politically stable jurisdictions.
