Clean Air Metals Reports New Drill Results from both the

Current Lake and Escape Lake Deposits of the Thunder

Bay North Project including 76.7m of 5.67g/t PdEq with

21.0m of 9.98g/t PdEq

Thunder Bay, ON, September 7 , 2021 – Clean Air Metals Inc. (“ Clean Air Metals ” or the

“Company”) (TSXV: AIR; FRA: CKU; OTCQB: CLRMF) is pleased to announce new assay results from

the drilling campaign currently underway at the Company’s Thunder Bay North Project (the

“Project”). Assay highlights (from Table 1) include:

For the Escape Lake deposit:

• Hole ELR21 -077 intersected 76.6m grading 5.67g/t Palladium Equivalents (PdEq) 1

composed of 1.63g/t Platinum (Pt), 2.14g/t Palladium (Pd), 0.81% Copper (Cu), 0. 41%

Nickel (Ni) from 3 45.0m-421.6m downhole including 21.0m grading 9.98g/t PdEq

composed of 2.97 g/t Platinum (Pt), 3.93g/t Palladium (Pd), 1.41% Copper (Cu), 0.68%

Nickel (Ni) from 392.0m-413.0m downhole (Figure 1).

The Escape Lake Deposit has been the focus of the majority of the drilling over the past 14 months.

Since the maiden resource published in January 2021 of 505,369 ounces at 3.67 g/t PdEq in 4 .28

million tonnes, the Clean Air Metals team has successfully expanded the size of the Escape South

High Grade Zone and demonstrated approximately 700m of mineralization along trend. Hole

ELR21-077 with its significant thickness and grade appears to further expand the edge of the

Escape Lake High Grade Zone and demonstrates potential contribution of scale of the Escape Lake

Deposit to the overall Thunder Bay North Project. An updated mineral resource for the Escape

Lake Deposit is currently planned for Q1 2022.

The Current Lake Deposit has a well-defined Indicated mineral resource of 1,328,789 PdEq ounces

at a grade o f 3.44 g/t PdEq in 11.99 million tonnes and is currently well advanced with a

Preliminary Economic Assessment (PEA) study to be published in Q4 this year. The PEA-level mine

stope optimization in the Beaver Lake Zone area of the Current Lake Deposit may be enhanced by

the results of a recent infill drill program, including the following highlight results:

• Hole CL21-007 which intersected 13.49m grading 6.09 g/t PdEq composed of 2.79 g/t

Platinum (Pt), 2.61g/t Palladium (Pd), 0.52% Copper (Cu) and 0. 31% Nickel (Ni) from

140.2 – 153.7m downhole (Figure 2).

• Hole CL21-006 which intersected 14.83m grading 4.65 g/t PdEq composed of 1.92 g/t

Platinum (Pt), 1.90g/t Palladium (Pd), 0.46% Copper (Cu) and 0.2 8% Nickel (Ni) from

152.2 – 167.0m downhole (Figure 2).

• Hole CL21-008 which intersected 20.0m grading 3.43 g/t PdEq composed of 1.55 g/t

Platinum (Pt), 1.41g/t Palladium (Pd), 0.26% Copper (Cu) and 0. 20% Nickel (Ni) from

142.0 – 162.0m downhole (Figure 2).

Mineral resource endowment and palladium -equivalents are quoted pursuant to the T echnical

Report and Mineral Resource Estimate for the Thunder Bay North Project, Thunder Bay, Ontario,

effective date January 20, 2021 , posted to SEDAR March 4, 2021. Prepared by Nordmin

Engineering Ltd.- QP Glen Kuntz, P.Geo. Ontario.

Update on Metallurgy and PEA

Metallurgical optimization studies continue with Blue Coast Research of British Columbia. The

results of the metallurgical studies on drill-derived bulk sample material and independent analysis

of smelter recoveries and smelter payables are expected to input directly into a Preliminary

Economic Assessment (PEA) mine cash flow model planned for publication in early Q4/2021.

Abraham Drost, CEO of Clean Air Met als stated that “ infill assay results from the Beaver Lake

Zone of the Current Lake deposit infill drilling (“CL” holes) is an affirmation of our understanding

of the deposit and ability to target and execute on drilling which has the potential to materially

impact the results of the upcoming PEA. This bodes well for future upgrade drilling on the large

inferred resource down plunge which will occur at future study phases. The Company is looking

forward to publication of a PEA in Q4/21 based solely on the C urrent Lake Deposit. As with the

mineral resource estimate published in March, 2021, the PEA will be based on a ramp -access

underground mine model constraining the existing mineral resource. In addition to the Current

Lake Deposit, the potential to add sca le to the Thunder Bay North Project with feed from the

Escape Lake Deposit is potentially accretive to the project.

Recent drought conditions and regional forest fire activity imposed certain restrictions and

precluded the construction of new drill pads o n the Thunder Bay North Project. The Clean Air

Metals geology team found innovative ways of keeping the drills running, including utilizing

previous pads using angled holes to test edges and in the case of Hole ELR21 -077, to expand the

margins of the Escap e South High Grade Zone. Fortunately, the drought has ended and the fire

ban has now lifted. The present round of assay results is also being added to the Escape Lake

deposit database (“ELR” holes) which will result in a revised mineral resource estimate in Q1/22.”

COVID Policy

Clean Air Metals has adopted COVID -19 avoidance and personal protection measures for its

geological staff, drilling contractor and service suppliers. Personnel are required to maintain

physical distance, use Personal Protective Equipment (PPE), self-monitor and self-isolate or elect

to work from home. Management had previously eliminated plans for a camp setup to service a

planned diamond drill campaign on the Escape Lake Project. The Company is aware of Thunder

Bay Health Unit guidelines that provide for “ mandatory” self- isolation for returning overseas

travel. The guidelines also “strongly recommend” self - monitoring and self- isolation as needed

after travel into the Northwest region from other areas of the province and interprovincially.

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. Core samples from selected intervals are individually

bagged and tagged, gathered up in larger sealed poly bags and shipped to the sample prep facility

in Thunder Bay, ON under custody of Clean Air personnel at all times. Sample preparation is

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

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

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

consisting of the insertion of blind blanks, duplicates , and certified Palladium -Platinum and

Copper-Nickel standards into the sample stream. The insertion procedure results in a minimum

of 11% to 12% 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 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 method consisting of either ICP -AES or atomic absorption spectrometry (AAS)

techniques.
