Lomiko announces update on its regional graphite exploration program in the

Grenville region, Quebec

Montreal, Quebec – July 11th, 2023 - Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals” or the

“Company”) is pleased to report the results of a successful Beep -Mat prospecting and sampling

program recently completed by Breakaway Exploration Management Inc. (“Breakaway”) on the

Grenville Graphite Mineral Belt regional claims . The “Grenville” project includes 268 mineral

claims covering 15,639 hectares on six blocks in the Laurentian region of Quebec , approximately

200 kilometers northwest of Montréal within a 100 km radius of the Company’s flagship La Loutre

graphite project. This is located 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.

Belinda Labatte, CEO and Director: “These results are encouraging and show the pote ntial to

develop the graphite potential surrounding La Loutre . Th ese new discoveries improve our

understanding of the area and how we can look at a responsible approach to graphite development

in the region.”

Highlights

• 10 new high-grade graphite showings discovered;

• 37 of 57 grab samples greater than 5.00% graphite;

• Maximum value of 22.90% graphite found on Ruisseau block;

• Graphite zones traced up to lengths of 1000 metres on the surface.

The field program consisted of ground- testing 15 of the 55 high- priority targets identified as

prospective for graphite mineralization by the 1518- line kilometer, heliborne, magnetic and ti me-

domain electromagnetic survey completed by the Company over the Grenville project in 2022.

Work was completed on the Boyd, Dieppe, Meloche, Ruisseau, and Tremblant blocks (Figure 1).

The North Low block was not investigated due to its relative isolation with respect to the other five

blocks.

The Beep -Mat is an electromagnetic survey instrument designed and manufactured by

Instrumentation GDD Inc. in Quebec City, Quebec. The unit is pulled on the ground and takes

continuous readings while the operator walks. It makes a distinctive audible “Beep” when detecting

a conductive object within a radius of three metres. The Beep- Mat was found to be very effective

at locating graphite mineralization, which is inherently highly conductive, on the Grenville project.

A total of 10 new surface graphite showings were discovered with the Beep- Mat. Many of these

showings returned very strong graphite values from selective grab samples , as outlined in Table 1

and several new graphite zones were traced up to 1000 metres on the surface.

The Ruisseau block returned strong results with values ranging from 0.16 to 22.90 percent graphite

(“% Cg”) with 19 of 26 values greater than 5.00% Cg. Six new graphite showings were discovered

in the western and southern parts of the block. Five of these showings consistently returned graphite

values greater than 10.00% Cg. Eleven targets in the eastern half of the block were not prospected

or sampled.

Total 57

At Boyd, only one of eight targets was visited but at this target a new zone of strong graphite

mineralization was demonstrated with values from 5.61 to 17.10% Cg for almost 1,000 metres on

surface.

At Meloche, strong graphite values from 5.62 to 12.00% Cg were obtained from the previously

known Lac Pimoden-NE showing. A new showing in the south- central part of the block returned

6.02% Cg from a single grab sample. Three targets in the northwest part and one target in the

southeast part were not prospected or sampled.

At Tremblant, four new showings were discovered with three of these showings returning graphite

values greater than 5.00% Cg with a maximum value of 13.90% Cg. At Dieppe, two graphite zones

were discovered but both returned relatively low graphite values. Prospecting at Dieppe was

hampered by very rough terrain with many steep cliffs. Seven targets remain to be prospected.

The methodology developed by Breakaway for examining targets on the Grenville project has

proven to be very successful for discovering graphite mineralization on surface. Forty high-priority

graphite targets remain to be prospected and sampled.

QAQC and Analytical Procedures

Each sample was photographed and then placed in a plastic bag with a uniquely numbered tag. The

tag number was marked in indelible ink on the outside of the bag and the bag was sealed with a

plastic tie-wrap. One certified reference material standard and one blank were included in each

batch of 21 samples. For shipping, samples were placed in rice bags that were individually sealed

with numbered, tamper-proof security tags. The rice bags were delivered in person to Activation

Laboratories Ltd. (“Actlabs”) in Val -d’Or, Quebec and subsequently transported by Actlabs to its

Ancaster, Ontario facility.

At Actlabs Ancaster, the samples were crushed to 80% passing 2mm and then riffle split to a 250g

sub-sample that was pulverized to pulp 95% passing 105μm (Actlabs Code RX1). The sample pulps

were then analyzed for per cent graphitic carbon by mild hydrochloric acid digestion followed by

combustion in an infrared induction furnace (Actlabs Code 8Cg). Actlabs is accredited under ISO

9001:2015 registration and is independent of the Company.

About Lomiko Metals Inc.

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

The La Loutre project site is located 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 kilometres 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 belonging to the Grenville Province of the Precambrian Canadian

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

4

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

temperature metamorphism.

In addition to La Loutre, Lomiko is working with Critical Elements Lithium Corporation towards

earning its 70% stake in the Bourier Project as per the option agreement announced on April 27 th,

2021. The B ourier 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.

On behalf of the Board,
