Lomiko Metals Announces Receipt of Province of Quebec Permits to initiate

the bulk sample works at La Loutre Graphite project and update on private

placement

NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR

DISSEMINATION IN THE UNITED STATES

June 30th, 2025 – Montreal, Québec: Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko” or the

“Company”) is pleased to announce the receipt of the Autorisation pour travaux d’exploration à

impacts (“ATI”) for its planned 250-tonne bulk sample at La Loutre Graphite deposit. This bulk

sample is an essential aspect of the ongoing research and development to scale up and confirm the

process of producing anode material. The bulk sample work will be done in the fall, after the

holiday and hunting seasons. Some noninvasive work and mapping will start through the summer.

The Company will continue to provide transparent and full information and comply with

ECOLOGO for all field work.

Gordana Slepcev, CEO, President, and Director, stated: “We are happy to announce that we have

received the ATI permits to initiate the field and work on the 250 tonne bulk sample excavation

and processing. The bulk sample will be used to start the work on the scaling up of the anode

testing work and demonstrate on a larger scale the results already achieved in the lab-scale testing,

showing positive results for use in anode battery technology. This work is supported by a

contribution agreement for building Canadian expertise and processing capabilities in graphite.

Graphite is one of the six priority critical minerals.”

In addition, Lomiko is presently in a permitting phase, as previously announced, to commence

geotechnical site investigations with Ministère des Ressources naturelles et des Forêts (“MRNF”).

All Canadian contractors have been announced, and Lomiko is proud to have retained the vast

majority, and few exceptions, with Southern Quebec-based consulting and contractor team for the

Pre-Feasibility Studies. See press releases dated April 24, 2025 and May 21, 2025, for details.

Lomiko will continue to engage with community members and remains open to answering

questions via regular virtual meetings, the company’s Facebook page and direct emails. The

information sessions are published on the company’s Facebook page and website.

as that term is defined under National Instrument 43-101, Standards of Disclosure for Mineral

Projects.

Private placement

The Company further advises that it will not seek approval from the TSX-V for a second extension

About Lomiko Metals Inc.

The Company holds mineral interests in its La Loutre graphite development in southern Quebec.

The La Loutre project site is within the Kitigan Zibi Anishinabeg (KZA) First Nation’s territory.

The KZA First Nation is part of the Algonquin Nation, and the KZA traditional territory is situated

within the Outaouais and Laurentides regions. Located 180 kilometers northwest of Montreal, the

property consists of one large, continuous block with 76 mineral claims totaling 4,528 hectares

(45.3 km2).

The Property is underlain by rocks from the Grenville Province of the Precambrian Canadian

Shield. The Grenville was formed under conditions that were very favorable for the development

of coarse-grained, flake-type graphite mineralization from organic-rich material during high-

temperature metamorphism.

Lomiko Metals published an updated Mineral Resource Estimate (MRE) in a NI 43-101 Technical

Report and Mineral Resource Estimate Update for the La Loutre Project, Quebec, Canada,

prepared by InnovExplo on May 11th, 2023, which estimated 64.7 million tonnes of Indicated

Mineral Resources averaging 4.59% Cg per tonne for 3.0 million tonnes of graphite, a tonnage

increase of 184%. Indicated Mineral Resources increased by 41.5 million tonnes as a result of the

2022 drilling campaign, from 17.5 million tonnes in 2021 MRE with additional Mineral resources

reported down-dip and within marble units resulted in the addition of 17.5 million tonnes of

Inferred Mineral Resources averaging 3.51% Cg per tonne for 0.65 million tonnes of contained

graphite; and the additional 13,107 metres of infill drilling in 79 holes completed in 2022 combined

with the refinement of the deposit and structural models contributed to the addition of most of the

Inferred Mineral Resources to the Indicated Mineral Resource category, relative to the 2021

Mineral Resource Estimate. The MRE assumes a US$1,098.07 per tonne graphite price and a cut-

off grade of 1.50% Cg (graphitic carbon). The independent and qualified persons for the mineral

resource estimate, as defined by NI 43 101, are Marina Iund, P.Geo. (InnovExplo Inc.), Martin

Perron, P.Eng. (InnovExplo Inc.)., Simon Boudreau, P.Eng. (InnovExplo Inc.). and Pierre Roy,

P.Eng. (Soutex Inc.). The effective date of the estimate is May 11, 2023.

The Company also holds interest in seven early-stage projects in southern Quebec, including

Ruisseau, Tremblant, Meloche, Boyd, Dieppe, North Low and Carmin, covering 328 claims in

total on 7 early-stage projects covering 18,622 hectares in the Laurentian region of Quebec and

within KZA territory.

The stage graphite portfolio consists of 328 claims in total on seven early-stage projects covering

18,622 hectares in southern Quebec. The grades presented below for the Laurentides graphite

portfolio were press-released on January 7 th, 2025. ( https://lomiko.com/news/lomiko-metals-

new-zones-at-the-ruisseau-project-spanning-over-3-kilometres-long/)

• Ruisseau–grades up to 27.9 percent carbon graphite (“% Cg”) from four distinct high grade

mineralized zones that are over 3km long;

• Meloche –grades up to 13.3% Cg from two distinct mineralized clusters;

• Tremblant –grades up to 11.6% Cg from numerous, widespread spot anomalies; and

• Dieppe –grades up to 6.82% Cg from numerous, widespread spot anomalies and a distinct

mineralized cluster.

• Boyd–8 samples grades range from 5.61% Cg to 17.10 %Cg with all samples above 5.00% Cg.

The technical content regarding the exploration results presented was reviewed by Mark Fekete,

P.Geo. who acts as an independent consultant to the Company and is the Qualified Person.

In addition to La Loutre, Lomiko has earned a 49% stake in the Bourier Project from Critical

Elements Lithium Corporation as per the option agreement announced on April 27 th, 2021. The

Bourier project site is located near Nemaska Lithium and Critical Elements south-east of the Eeyou

Istchee James Bay territory in Quebec, which consists of 203 claims for a total ground position of

10,252.20 hectares (102.52 km2), in Canada’s lithium triangle near the James Bay region of

Quebec that has historically housed lithium deposits and mineralization trends.

The Yellow Fox Property is located approximately 10 km southwest of the Town of Glenwood

NL, and south of the Trans-Canada Highway. The Property occurs within NTS map sheets 02D/14

and 15 with excellent access along several logging and skidder roads originating from

Glenwood. The main Yellow Fox showing is located in the central part of License 027536M, 5km

from the western end of Gander Lake.

This property is on the same trend as the past-producing antimony mine Beaver Brook, which is

located 25km southwest of the property. Yellow Fox is an early-stage exploration property

prospective in antimony, gold, and silver where historic works returned samples anomalous in gold

(Au), antimony (Sb), lead (Pb), zinc (Zn), and silver (Ag). The trenching exposed the rocks,

resulting in grab samples to 59.43g/t Au, 11.10% Sb, 7.00% Zn, 72.90g/t Ag, and 5.50% Pb in

arsenopyrite-stibnite veins within altered monzogranite. (See Metals Creek assessment report at
