Clean Air Metals Hits Multiple High-PGE Massive Sulfide Veinlets 450m North of Escape High Grade Zone

THUNDER BAY, July 6, 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 at the Escape Lake Deposit currently underway at the Company's Thunder Bay North Project (the "Project"). Highlights include:

• Hole ELR21-067 intersected a massive sulphide lens grading 41.2 g/t PdEq¹ composed of 12.9g/t Palladium (Pd), 15.5g/t Platinum (Pt), 7.94% Copper (Cu), 2.41% Nickel (Ni), over 0.2m from 432.2 - 434.4m downhole. This intercept of injection-textured massive sulphides (Figure 2) was located in the Bullseye Magnetic Anomaly 450m north of the centroid of the Escape South High Grade Zone pod (which contains 2,351,310 tonnes grading 4.82g/t PdEq). The ppm metal ratios for Cu/Pt+Pd (=2875) and Ni/Pt+Pd (=875) indicating off-the-chart PGE-enrichment found in this sample is in the field of similar high-PGE metal ratios found in the Norilsk copper-nickel deposits in Russia (Figure 5).

• Previously, Hole ELR21-041 intersected a massive sulphide lens 100m to the southeast, grading 31.8 g/t PdEq composed of 7.93g/t Palladium (Pd), 6.41g/t Platinum (Pt), 4.76% Copper (Cu), 2.5% Nickel (Ni), 0.151% Cobalt (Co) over 0.5m from 337.0 - 337.5m downhole. This intercept of delicate "loop-textured" massive sulphides (Figure 1) was also located in the Bullseye Magnetic Anomaly 350m north of the centroid of the Escape South High Grade Zone pod. The ppm metal ratios for Cu/Pt+Pd (=3300) and Ni/Pt+Pd (=1740) found in this sample closely match similar metal ratios found in the high-PGE Norilsk copper-nickel deposits in Russia (Figure 5).

This cluster of Norilsk-style Copper-Nickel-Cobalt massive sulphide veinlets or injections (Figures 2, 3, 4, 5) with substantial Platinum and Palladium in the Escape Lake Deposit system suggests leakage from a possible source in the area of the Bullseye Magnetic Anomaly (Figure 1). The latter is a feature with a 200m diameter core and a large reverse polarity ring, located at a west-trending inflection point in the Escape conduit system, underlain by multiple intersecting faults and other lineations and structural features (Figure 1). Other average deposit grade highlights, from intersections located in the core of the Bullseye Magnetic Anomaly feature, include:

• Hole ELR21-059A intersected 6.0m grading 4.3 g/t PdEq composed of 1.53g/t Palladium (Pd), 1.37g/t Platinum (Pt), 0.62% Copper (Cu) and 0.32% Nickel (Ni) from 311.0 - 317.0m downhole;
• Hole ELR21-046 intersected 5.1m grading 4.9 g/t PdEq composed of 1.89g/t Palladium (Pd), 1.68g/t Platinum (Pt), 0.73% Copper (Cu) and 0.25% Nickel (Ni) from 337.4 - 342.45m downhole.

The inherent fertility of the Escape Lake magma conduit deposit is well illustrated by the recent mineral resource update reported on January 20, 2021. The Escape Lake Deposit has an overall Indicated mineral resource of 505,369 ounces at 3.67g/t PdEq in 4,286,220 tonnes and is geologically open along trend. The adjacent Current Lake Deposit has an Indicated mineral resource of 1,328,789 oz PdEq at an average grade of 3.44 g/t PdEq in 11,999,177 tonnes.

Mineral resource endowment is quoted pursuant to the NI 43-101 Technical 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.

Update on Metallurgy and PEA

With the Company's 2020 investment of CAD$4.5 million into 19,000m of drilling at Escape in 2020, the average cost of discovery was approximately $9.00 per Indicated ounce PdEq. A revised, updated mineral resource update for the Escape Deposit and overall project is expected to be calculated in Q1/2022.

Metallurgical optimization studies continue with Blue Coast Research of British Columbia. The results of the studies and independent analysis of smelter recoveries and smelter payables are expected to input directly into a Preliminary Economic Assessment (PEA) mine model planned for publication in early Q4/2021.

Abraham Drost, CEO of Clean Air Metals stated that "the exploration team has discovered a cluster of massive sulphide material in a locus of intersecting structures coincident with a change of direction or inflection point in the Escape Deposit. Notably, the net-textured Escape South High Grade Zone is also located at what is interpreted as an inflection point 400m south, along the deep crustal Escape Lake Fault. We have confirmed these inflection points are important localizers of mineralization within the Escape conduit. The Company is using various borehole and surface electromagnetic techniques to develop follow-up exploration targets in the continuing search for a massive sulphide deposit in the Thunder Bay North mineral conduit system.

The Company is looking forward to crystallizing value in Q4/21 with publication of a benchmark PEA at the Current Lake Deposit, using a ramp-access underground mine model constraining the existing mineral resource. The potential to also add scale to this remarkable Platinum and Palladium Project with potential feed from the Escape Deposit is an accomplishment resulting from the consolidation of the two assets last year."

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. Mineral Exploration and Development has been deemed an essential service in the Province of Ontario (http://www.netnewsledger.com/2020/03/23/ontario-covid-19-business-allowed-to-remain-open-list-march-23-2020/).
