Lomiko Metals Inc. Delivers Positive PEA For La Loutre Graphite

Project

Pre-tax NPV of C$314M with 28.3% IRR at US$916/t Cg; after-tax NPV of 186M with 21.5% IRR

MONTREAL--(July 29, 2021) Lomiko Metals Inc. (Lomiko) ((TSX-V: LMR, OTC: LMRMF, FSE: DH8C)) ("Lomiko

Metals Inc or “Lomiko" or the "Corporation") is pleased to announce positive results from the Preliminary Economic

Assessment (“PEA”) on its 100 percent-owned La Loutre Project in south-eastern Quebec. The PEA was completed

by Ausenco Engineering Canada Inc. (“Ausenco”) in accordance with National Instrument 43-101 (“NI 43-101”).

Lomiko now aims to initiate a Preliminary Feasibility Study (PFS) to advance its La Loutre Project towards production

as part of a staged development strategy while continuing its aggressive drilling programs to maximize value creation.

Highlights of the PEA (all figures are stated in Canadian dollars unless otherwise stated):

• Long-term Weighted-Average1 Graphite Price US$916/t Cg conc. (graphitic carbon concentrate)

• Exchange rate: C$1.00 = US$0.75

• Pre-tax NPV (8%) of C$313.6M

• After-tax NPV (8%) of C$185.6M

• Pre-tax IRR of 28.3%

• After-tax IRR of 21.5%

• Pre-tax payback period of 3.3 years

• After-tax payback period 4.2 years

• Initial capital of (“CAPEX”) of C$236.1M including mine pre-production, processing, infrastructure (roads,

power line construction, co-disposal tailings facility, ancillary buildings, and water management)

• Life of mine processing period (“LOM”) of 14.7 years

• Average LOM strip ratio (Waste:Mineralization) of 4.04:1

• LOM plant production of 21,874 Kilotons (kt=1,000 metric tonnes) of mill feed yielding 1,436 kt of graphite

concentrate grading 95.0% Cg.

• Average annual graphite concentrate production of 108 kt for the first eight years; LOM average annual

production of 97.4 kt.

• Average graphite mill head grade of 7.44% Cg for the first eight years; LOM average graphite mill head grade

of 6.67% Cg.

• Average LOM recovery of 93.5% Cg.

• Measured + Indicated resource at the base case cut-off grade of 1.5% Cg of 23,165 kt at a 4.51% Cg grade for

1.04 Mt of graphite.

• Inferred resource at the base case cut-off grade of 1.5% Cg of 46,821 kt at a 4.01% Cg grade for 1.9Mt of

graphite.

• Cash Cost of US$386 per tonne of graphite concentrate

• All-in Sustaining Cost (“AISC”) of US$406 per tonne of graphite concentrate

The Lomiko team is pleased to present the results of a PEA on its La Loutre Project, clearly demonstrating its

potential for the Corporation to become a major North American graphite producer, with a positive after-tax Internal

Rate of Return (“IRR”) of 21.5% and after-tax Net Present Value (“NPV”) of C$186M. The PEA supports an open pit

project with production spanning 14.7 years with robust economics at a US$916/tonne Cg sale price, with very

attractive cash costs and AISC, low CAPEX and low capital intensity. The first eight years will target production

averaging 108 kt/a payable graphite concentrate peaking at 112 kt/a in year 4.

“La Loutre has shown it has the potential to become a highly profitable graphite mine in one of the most prolific

producing regions in Canada. The La Loutre PEA was produced by the Ausenco team, one of the most experienced

and reputable engineering firms working on mining projects in Canada. With further drill programs, we will continue to

add to and upgrade resources as we seek to move the project forward towards production,” said A Paul Gill,

President, CEO and director, Lomiko.

The La Loutre Project PEA indicates the property has the geological potential to extend the mine life beyond the initial

14.7 years presented in the PEA as well as the opportunity to expand the scale of production by increasing the

mineral resource through ongoing exploration and drilling. The Company’s goal is for La Loutre to be a cornerstone

mine for its future growth in a mining friendly jurisdiction. With a strong treasury to support their next steps, the

Company plans to commence a Preliminary Feasibility Study (PFS) and Environmental Impact Studies while

continuing to explore the geological potential of its La Loutre property.

“The development of Canada-USA and Canada-EU critical minerals collaboration agreements gives access for

graphite products in these markets. There is a focus on projects with environmental, social and governance (ESG)

acceptability which Lomiko has also adopted. The strict criteria for the report should result in competitively-priced

graphite for customers in the North America and European markets. These recent agreements between Canada and

the USA and Canada and Europe have identified graphite as a critical element that will be part of a new supply chain.

Lomiko is ready to maximize La Loutre’s value by advancing the studies to further refine and de-risk the project,”

added Gill.

Lomiko looks forward to working with its partners in the MRC of Papineau region including the Lac-des-Plages and

the Duhamel municipalities, as well as the surrounding First Nations communities. We will also continue to work

closely with the Quebec and Federal governments to advance the La Loutre Project.

Overview

Ausenco was appointed as lead PEA consultant on February 22, 2021, in accordance with National Instrument 43-

101 – Standards of Disclosure for Mineral Projects ("NI 43-101"). Ausenco is the lead consultant responsible for the

overall development of the PEA, including the processing, major infrastructure, hydrogeology, hydrology,

environmental, co-disposal of mine waste rock and mill tailings, mining and economic assessment. Ausenco’s

specialist ESG group Hemmera Envirochem Inc., provided environmental support and Moose Mountain Technical

Services was responsible for the resource estimate and mine design. Metpro Management Inc. (Metpro) was

responsible for metallurgy.

The La Loutre Project is located in the Nominingue-Chénéville Deformation Zone in Quebec. The Property consists of

one large contiguous block of 42 mineral claims totaling 2,508.97 hectares (25.09 km2) and is located approximately

117 km northwest of Montréal in southern Québec, 230 km southwest of the Nouveau Monde Matawinie Project and

100 km southeast of the Imerys Graphite & Carbon Lac-des-îles mine.

Financial Analysis

The economic analysis was performed assuming an 8% discount rate. This analysis shows a projected pre-tax NPV

8% of $313.6M, internal rate of return IRR is 28.3% and payback period of 3.3 years. On an after-tax basis, an NPV

8% of $186M, IRR of 21.5% and payback period of 4.2 years is expected. A summary of the project economics is

listed in (Table 1).

The size distribution as noted in Table 1 was derived from the lock cycle testing (LCT) on the Master composite by

SGS Canada Inc. Benchmark Mineral Intelligence (Benchmark) provided pricing information based on Mesh Size

only. The prices were derived based on Benchmark forecasted graphite prices and is noted in Table 1.

Mineral Resource

The mineral resource is estimated from a drill hole database containing 117 drill holes consisting of 15,160 metres of

drilling and 8,850 assay intervals.

The total Mineral Resource Estimate (MRE) is summarized in Table 5, with the base case cut-off of 1.5% Graphite

highlighted. A Lerchs-Grossman resource pit has been constructed using the 150% pit case based on the prices,

offsite costs, metallurgical recovery and graphite prices used for the economic analysis thus confining the resource to

a “reasonable prospects of eventual economic extraction” pit shape. The cut-off grade is based on a processing cost

of CDN$11.85/tonne, and General and Administrative Costs of CDN$2.37/tonne and a C$1.00 = US$0.75 as

summarized in the notes below. A cut-off grade of 1.5% Cg has been used for the base case of the resource

estimate, which more than covers the Process and G&A costs.

These mineral resource estimates include inferred mineral resources that are considered too speculative geologically

to have economic considerations applied to them that would enable them to be categorized as mineral reserves.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Practices Guidelines.

2. Mineral Resources are reported inclusive of Mineral Reserves.

3. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

4. The Mineral Resource has been confined by a “reasonable prospects of eventual economic extraction” pit using the

following assumptions: Exchange Rate C$1.00 = US$0.75; Weighted average price of graphite of US$ 916/tonne;

100% payable; Offsite costs including transportation and insurance of CDN$37.42/tonne; a 1.5% NSR royalty;

5. Pit slope angles are 45º below overburden, 20o in overburden.

6. The specific gravity of the deposit is 2.86 in unmineralized and low-grade zones and 2.78 in high-grade zones (within

solids above a 4% Graphite grade).
