Northern Graphite Files Appeal of Lac des Iles Mining Lease Suspension

Northern Graphite Files Appeal of Lac des Iles

Mining Lease Suspension

Ottawa, Ontario--(Newsfile Corp. - September 9, 2026) - Northern Graphite Corporation

(TSXV: NGC)

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

(

the "

Company

" or "

Northern

")

announces that it filed

an appeal with the Court of Quebec on September 8, 2026, contesting the decision by Quebec's

Ministère des Ressources naturelles et des Forêts ("

MRNF

") to suspend the mining lease for the

Company's Lac des Iles ("

LDI

") graphite mine.

The MRNF's decision relates to an outstanding payment associated with an increase in the amount of

the financial guarantee sought from the Company for the restoration of the site upon completion of its

mining activities. Northern disagrees with the MRNF's interpretation of the applicable requirements

under the

Mining Act

(Quebec) and its regulations and maintains that it is not in default.

The filing of the appeal stays the suspension until a final decision is rendered by the Court of Quebec.

Accordingly, as stated in an August 19, 2026 press release, the LDI mining lease remains in effect

during the appeal process.

The Company will provide further updates as material developments occur.

About Northern Graphite

Northern is a Canadian, TSX Venture Exchange listed company that is the only flake graphite miner 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 Lac des Iles mine in Quebec, where the Company plans to boost

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.
