Lomiko identifies 55 new prospective targets in the Grenville Graphite Mineral Belt and

updates exploration on Bourier Lithium Project

Montreal, Quebec – February 21, 2023 - Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals”

or the “Company”) is pleased to announce the following regional exploration updates. The

Company has staked approximately 268 mineral claims covering 15,639 hectares on six blocks in

the Laurentian region of Quebec, approximately 200 kilometres northwest of Montréal within the

Kitigan Zibi First Nation ’s territory. These new claim blocks lie within a 100 km radius of the

Company’s flagship La Loutre graphite project.

Highlights :

• 1518-line kilometres of heliborne magnetic and time -domain electromagnetic surveys

completed over the six Grenville graphite properties (Figure 1)

• 55 targets prospective for graphite mineralization identified

• Targets to be ground tested with Beep-Mat prospecting and sampling

Within the Central Metasedimentary Belt of the Grenville Geological Province, graphite

mineralization is known to occur in conjunction with various types and amounts of sulphides

suggesting that a combined geophysical High-resolution magnetic ( “MAG”) and time -domain

electromagnetic ( “TDEM”) response is expected from graphite -bearing rock units. The strong

correlation of TDEM and MAG anomalies implies that magnetic sulphide minerals are likely to

compose at least part of the anomaly sources. These are considered first steps in developing natural

flake graphite exploration campaigns.

Belinda Labatte, CEO stated: “We are very ple ased to see that the geophysical surveys we

conducted over the summer on our new graphite properties in the Grenville belt have returned very

encouraging results with previous visible graphite occurrences observed on several of the claims.

We intend to follow up on the prospective targets identified on all six properties with Beep-Map

prospecting and sampling later in 2023. This method successfully found the La Loutre deposit

currently at the Pre -Feasibility Stage. Those positive results fit into our strategy to create a

responsible regional solution for natural flake graphite development in Southern Quebec and we

are looking forward to working with Kitigan Zibi First Nation and local communities to further

develop those properties. At Bourier, we have a massive claim package to explore and we continue

our earlier soil and surface sampling test to determine the most prospective pegmatite anomalies.”

The 179-line-km survey flown over the 28- claim Boyd project located adjacent to the historical

Standard graphite deposit identified 260 TDEM point anomalies with 65 having an intermediate

to strong conductive response. Seven linear TDEM trends show strong correlation with magnetic

trends and are considered prospective targets for graphit e-sulphide mineralization. Three other

2

TDEM trends are associated with MAG lows or do not show any clear correlation to magnetic

data. Graphite hosted within non- magnetic marble rocks may be the source of TDEM responses

of this sort.

The 175-line-km heli borne survey flown over the 33- claim Meloche project located 25 km

southeast of Mont-Laurier identified 229 TDEM point anomalies with 33 having an intermediate

conductive response. Two linear TDEM trends and three spot anomalies show strong correlation

with magnetic trends and are considered prospective targets for graphite -sulphide mineralization.

Two of these targets correspond with known surface occurrences, including the Lac Meloche

occurrence where visible flake graphite has previously returned up to 13.85% graphite and the Lac

Pimodan-NE occurrence where visible flake graphite has previously returned up to 10.13%

graphite (refer to reference no.2). A sixth target is defined by two TDEM anomalies over a MAG

low.

The 372-line-km survey flown over the 69- claim Dieppe project located 55 km north of Mont -

Laurier identified 320 TDEM point anomalies with 24 having an intermediate to strong conductive

response. Three linear TDEM trends show strong correlation with magnetic trends and are

considered prospective targets for graphite -sulphide mineralization. One of these targets

correspond with the known Lac Dieppe occurrence where visible flake graphite has previously

returned up to 11.6% graphite (refer to reference no.1). Three other TDEM trends are associated

with MAG lows or do not show any clear correlation to magnetic data. Graphite hosted within

non-magnetic marble rocks may be the source of TDEM responses of this sort.

The 246-line-km survey flown over the 47-claim Ruisseau project located 50 km ENE of Mont -

Laurier identified 538 TDEM point anomalies with 204 having an intermediate to very strong

conductive response . Eleven linear TDEM trends and three spot anomalies show strong

correlation with magnetic trends and are considered as prospective targets for graphite -sulphide

mineralization. Ten other TDEM trends are associated with MAG lows or do not show any clear

correlation to magnetic data. Graphite hosted within non-magnetic marble rocks may be the source

of TDEM responses of this sort.

The 315-line-km survey flown over the 52- claim Tremblant project located 25 km southeast of

Mont-Laurier identified 221 TDEM point anomalies with 31 having an intermediate conductive

response. Eight linear TDEM trends show strong correlation with magnetic trends and are

considered prospective targets for graphite-sulphide mineralization.

The 231-line-km survey flown over the 39- claim North Low project located 40 km north of

Gatineau identified 406 TDEM point anomalies with 21 having an intermediate to strong

conductive response. Two linear TDEM trends show strong correlation with magnetic trends and

are considered prospective targets for graphite -sulphide mineralization. Two other TDEM trends

are associated with MAG lows or do not show any clear correlation to magnetic data. Graphite

hosted within non-magnetic marble rocks may be the source of TDEM responses of this sort.

targets for graphite-sulphide mineralization on each claim block.

Bourier Exploration Update

The Bourier Lithium property consists of 203 mining claims, covering 102.6 km2, located in the

Nemiscau greenstone belt. The 2022 exploration program consisted of 1) intensifying the surface

rock sampling in the anomalous zones discovered during the 2021 field program, and 2) testing

new lithium-cesium-tantalum pegmatite (LCT-Pegmatite) targets.

The 2022 surface exploration program confirmed and extended the 2.5 km long SW-trending LCT-

Pegmatite corridor, which is in strike with the Lemare lithium- prospect owned by Critical

Elements Lithium Corp. In addition, the exploration program revealed a new LCT -Pegmatite

sector in the North of the Bourier Property.

Lomiko’s 2023 exploration activities at Bourier will consist of two phases; 1) a litho-geochemical

characterization study of pegmatites and host rocks, and reanalyses of soil samples using a lithium-

oriented geochemical package, and 2) the completion of soil surveys in favourable geological areas

in the North and in the South of the Bourier Property.
