Clean Air Metals Reports New Assays from Escape Deposit Delineation Drilling

THUNDER BAY, May 20, 2021 - Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV: AIR) (OTCQB: CLRMF) (FRA: CKU) is pleased to announce new assay results (Table 1 and Figure 1) from a series of "in-between" holes in the ongoing drill campaign at the Escape Conduit Trend currently underway with two drills at the Company's Thunder Bay North Project (the "Project"). A total of 30,000m of systematic delineation drilling connecting the Escape South and Steepledge South resource areas is planned for the Escape Lake Deposit in 2021.

Highlights (Table 1) include:

• Hole ELR21-049 intersected 31.0m of 0.96/t Palladium (Pd), 0.81g/t Platinum (Pt), 0.36% Copper (Cu) and 0.21% Nickel (Ni) from 304.0m - 335.0m downhole located between the Escape South High Grade Zone and the Steepledge North Zone.
• Hole ELR21-051 intersected 7.7m of 1.61g/t Palladium (Pd), 1.30g/t Platinum (Pt), 0.59% Copper (Cu) and 0.38% Nickel (Ni) from 350.2m - 357.83m downhole located between the Escape South High Grade Zone and the Steepledge North Zone.
• Hole ELR21-052 intersected 4.0m of 1.29g/t Palladium (Pd), 1.14g/t Platinum (Pt), 0.49% Copper (Cu) and 0.25% Nickel (Ni) from 346.0m - 350.0m downhole located between the Escape South High Grade Zone and the Steepledge North Zone.

The fertility of the Escape Lake magma conduit deposit is well illustrated by the maiden 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 between the Escape South and the Steepledge South resource areas.

The Current Lake Deposit in turn 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 estimates for both deposits are reported pursuant to the January 20, 2021 NI 43-101 Technical Report and Mineral Resource Estimate for the Thunder Bay North Project, Thunder Bay, Ontario, prepared by Nordmin Engineering Ltd. with QP Glen Kuntz, P.Geo, as posted to SEDAR on March 4, 2021.

Work also continues on drilling massive sulphide targets recently announced on April 21, 2021 (Figure 2). Based on the recent resource update and discovery of massive sulphides in the Escape Lake Deposit with Norilsk metal ratios and the completion of a structural analysis and MT geophysical surveys, the Company has committed to a substantial ramp up of drilling exploration investment on promising ultra-low resistivity targets at the base of both the Escape Lake and Current Lake magma conduit deposit systems.

Abraham Drost, CEO of Clean Air Metals stated that "the latest assays are reported in line with the Company's policy of reporting regular assay updates. We are happy to report that all holes intersected mineralization and are expected to add materially to a future mineral resource update at the Escape Lake deposit."

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/ ). The Company has procured the services of a locally staffed and serviced diamond drilling contractor to complete the diamond drilling program.
