Lomiko Announces the filing of the Technical Report for the Mineral Resources Estimate of

the La Loutre Natural Flake Graphite Property and Announces Adjustment on Resource

Tonnage and Grade

Montreal, Quebec – May 29, 2023 - Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals” or the

“Company”) is pleased to announce that it has filed the Mineral Resource Estimate (MRE)

Technical Report following National Instrument 43-101 – Disclosure Standards for Mining Projects

on its La Loutre Project, where Lomiko has mineral rights. The technical report entitled “NI 43-101

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

Canada” and dated May 26, 2023 (with an effective date of May 11, 2023) was prepared for Lomiko

by the firm InnovExplo of Val -d’Or. The independent technical report is available on SEDAR

(www.sedar.com) under the Lomiko issuer profile.

During the final validation and completion of the Technical Report, adjustments were made to the

mineral resource estimate statement disclosed in the April 13, 2023, news release and therefore the

mineral resource tonnage in all categories has been amended. The adjustments now show an increase

of 184% versus the previously published increase of 195% in tonnage for the Indicated Mineral

Resource Category. See the news release dated April 13, 2023 entitled “Lomiko announces Updated

Mineral Resource Estimate for La Loutre Natural Flake Graphite Property in Southern Quebec

Achieving 195% Increase in Tonnage in the Indicated Mineral Resource Category” which

summarized certain key results, assumptions and estimates contained in the Technical Report filed

on SEDAR. The adjustments also contributed to increasing the overall grade from 4.50% to 4.59%

which removed lower grade material from all categories. Mineral resources adjustments are

presented in Table 1 for the updated 2023 MRE statement which was filed.

Notes to accompany the Mineral Resource Estimate:

1. 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.

2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability. The mineral

resource estimate follows current CIM Definitions (2014) and CIM MRMR Best Practice Guidelines (2019).

3. The results are presented undiluted and are considered to have reasonable prospects of economic viability.

4. The estimate encompasses two mineralized domains (EV and Battery) using the grade of the adjacent material when

assayed or a value of zero when not assayed.

5. No capping was applied on 1.5m composites.

6. The estimate was completed using sub-block model in Leapfrog Edge 2022 with user block size of 5m x 5m x 5m and

minimum block size of 2.5m x 2.5m x 2.5m. Grades interpolation was obtained by ID2 using hard boundaries.

7. Bulk density values were applied by lithology (g/cm3): mineralized domain = 2.82; paragneiss = 2.8; quartzite = 2.73;

pegmatite = 2.63, marble = 2.75 and OB = 2.0.

8. The mineral resource estimate is classified as indicated and inferred. The Indicated mineral resource category is

defined with a minimum of three (3) drill holes in areas where the drill spacing is less than 55 m, and reasonable

geological and grade continuity have been demonstrated. The Inferred category is defined with a minimum of two (2) drill

holes in areas where the drill spacing is less than 100m, and reasonable geological and grade continuity have been

demonstrated. Clipping boundaries were used for classification based on those criteria.

9. The mineral resource estimate is pit-constrained with a bedrock slope angle of 50° and an overburden slope angle of

30°. It is reported at a graphite cut-off grade of 1.5%. The cut-off grade was calculated using the following parameters:

processing cost = C$13.04; product transporting cost = C$41.16; mining cost (rock) = C$3.70; mining cost (OB) = C$2.90;

graphite price = US$1,098.07 /tonne of graphite; USD:CAD exchange rate = 1.32; graphite recovery to concentrate

product = 94.7%. The cut-off grade should be re-evaluated in light of future prevailing market conditions (metal prices,

exchange rates, mining costs etc.).

10. The number of metric tons was rounded to the nearest thousand, following the recommendations in NI 43 101 and any

discrepancies in the totals are due to rounding effects.

11. The authors are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, or

marketing issues, or any other relevant issue not reported in the Technical Report, that could materially affect the Mineral

Resource Estimate.

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 totalling 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 favourable for the development

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

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.
