Expanding the Near-Surface High-Grade

Mineralization at the Thunder Bay North Project

Thunder Bay, ON, September 10, 2024 – Clean Air Metals Inc. (“Clean Air Metals” or

the “Company”) (TSX.V: AIR; FRA: CKU; OTCQB: CLRMF) is pleased to announce assay

results from the first two (2) holes drilled this summer at its 100%-owned Thunder Bay

North Critical Minerals Project (“TBN”).

Assay highlights include:

• 51.79 m of 4.92 g/t Pt, 4.66 g/t Pd, 1.07% Cu and 0.55% Ni from 86 m

downhole in Hole CL24-001, including

o 11.51 g/t Pt, 10.64 g/t Pd, 2.61% Cu and 1.25% Ni over 9.29 m from

128 m, and

o 25.82 g/t Pt, 24.50 g/t Pd, 6.94% Cu and 3.87 % Ni over 0.97 m from

136.3 m (Massive Sulphides).

• 31.40 m of 4.22g/t Pt, 4.04g/t Pd, 0.95% Cu and 0.56% Ni from 118 m

downhole in Hole CL24-003, including

o 12.25m of 5.56g/t Pt, 5.48 g/t Pd, 1.19% Cu, 0.70% Ni, from 123 m.

The recently completed summer drilling program targeted near-surface high-grade

zones within the Current deposit to better define their lateral continuity and tonnage

potential. These initial results confirm that high-grade mineralization extends beyond

what was outlined in the last resource model for this area (NI 43-101 technical report on

the Thunder Bay North Project, Ontario, Canada, SLR Consulting Canada Ltd, June 19,

2023). Results from hole CL24-003, along with adjacent holes, outline a potentially

larger high-grade core within this section of the intrusion than previously evaluated

(Figure 1).

Clean Air Metals’ CEO Mike Garbutt commented, “We are encouraged by this program's

first set of results. These exceptional grades, mineable widths, and near-surface location

support the future development of this buildable asset. We are focused on significantly

improving the TBN project economics by fully defining the highest value mineralization

within the Current and Escape deposits. The initial results from this program have

exceeded our expectations.”

The goal of the program is to target near-surface, high-grade zones of mineralization

and improve both the continuity and total mineral resource within these zones. The

remaining eight (8) holes of the drill program have been completed, and all have

intersected mineralization in four separate targets. The assays on these holes are

pending and will be released when received.

Early Drill Results Outline Improved Continuity

The new technical expertise brought to the project and led by Dr. Lionnel Djon resulted

in a revised geological template for the high-grade areas at Thunder Bay North that

mirrors flow processes similar to those associated with alluvial gold processes. In

employing this template, the first two holes successfully expanded the zone of thick,

high-grade pods along strike in the Lower Current zone. They also provide early “proof

of concept” that increasing data density with tighter drilling could further extend the

continuity of the high-grade mineralized zones within the deposit and contribute to

increased tonnage and grade.

Following results from the remaining drill holes of the summer 2024 campaign, the

Company will develop an exploration program designed to discover new high-grade

zones within the Current and Escape deposits and a resource delineation program to

increase the resources contained in the additional high-grade areas that occur at both

the Current and Escape deposits.

The Presence of Massive Sulphides is Significant

Hole CL24-001 intersected 0.97m of massive sulphides (Figure 2) near the base of the

intrusion, in a zone where reduced magma flow and cooling conditions promoted

sulphide settling and metal concentration, leading to the formation of high-grade

mineralization. Past drilling at the Current and Escape deposits has also intersected

pockets of high-grade massive sulphides in similar embayments in the intrusion. These

occurrences demonstrate the potential for these deposits to host additional massive

sulphide, and continued exploration work is needed to identify the feeder zone for this

material.

Drill Results Support the Strategy for Thunder Bay North Project Development

The positive results from this program support our view that both deposits together can

support a smaller tonnage, high-grade and low-capital cost mine plan. The higher-

grade mineralization is spatially distributed in distinct and separable zones that allow

for targeted extraction using traditional open-stope mining methods. This approach

will form the foundation for a future technical study following the results of the next

phase of drilling.

To further de-risk that project, the Company is contemplating a move to advanced

exploration that is highlighted by the potential extraction of a bulk sample from the

Bridge zone at the Current deposit. The goal for the bulk sample will be to validate the

high-grade mining approach outlined above, as well as quantify the metallurgical

performance of a toll milling scenario on a larger scale.

Other Activities

The Company received an exploration permit on August 6, 2024, for the other

intrusions located on the claim package – the Lone Island North and South and 025

intrusions. While no work is planned for this area in 2024, the Company is defining a

potential 2025 exploration program there.

Quality Assurance / Quality Control

Clean Air Metals uses ALS Global (“ALS”), a well-established and recognized mineral

assay and geochemical analytical services company. The Thunder Bay laboratory holds

ISO-9000 accreditation; the Vancouver facility holds ISO-17025 registration.

All NQ-sized drill core is cut with a diamond-tipped saw blade with half of the core

submitted to ALS for sample preparation and analysis. Sample preparation is

completed at the ALS sample preparation facility in Thunder Bay, ON, and analysis is

completed at the primary ALS assay laboratory in Vancouver, B.C.

Clean Air Metals follows a quality control procedure for its core assay sampling

program: inserting blind blanks and certified Palladium-Platinum and Copper-Nickel

standards into the sample stream. The insertion procedure follows industry standards

with control sample frequency depending on the length of the sampled interval.

Gold, platinum, and palladium are analyzed using fire assay (FA) with an inductively

coupled plasma mass spectrometry (ICP-MS) finish. Samples with grades above the

5

optimal ICP-MS detection limits are analyzed using an optical emission spectroscopy

method (ICP-OES).

Also, thirty-three (33) elements of each sample, including copper, nickel, silver,

chromium, cobalt, and sulphur, are analyzed by a multi-element analytical method

using the atomic emission spectroscopy (ICP-AES) technique following four-acid

digestion of the sample. When samples have grades above the optimal detection limits

for this analytical method, they are re-analyzed using a high-grade assay method with

an ICP finish.
