Clean Air Metals Reports Drilling Update from the Thunder Bay North Project, Thunder Bay, Ontario

Nov 2, 2021

THUNDER BAY, ON, Nov. 2, 2021 /CNW/ – Clean Air Metals Inc. (“Clean Air Metals” or the “Company“) (TSXV: AIR) (FRA: CKU) (OTC: CLRMF) is pleased to announce new assay results from the drilling campaign presently underway at the Company’s Thunder Bay North Project (the “Project“) from the Escape and Current magma conduit deposits.

The Escape Deposit has undergone systematic expansion drilling of nearly 30,000m since the maiden Indicated resource of 505,369 ounces PdEq¹ (3.67 g/t PdEq in 4.28 million tonnes reported January 20, 2021). The Current Deposit, 2.5km to the east (Figure 2), has a well-defined Indicated mineral resource of 1,328,789 PdEq¹ ounces (3.44 g/t PdEq in 11.99 million tonnes).

New assays from the Escape Deposit (Table 1) include:

Hole ELR21-085 which intersected 16.1m grading 4.20g/t Palladium Equivalents (PdEq)¹ composed of 1.58g/t Platinum (Pt), 1.27g/t Palladium (Pd), 0.52% Copper (Cu), 0.31% Nickel (Ni) (Figure 1).

New assays from the Current Deposit (Table 2) include:

Hole CL21-021 which intersected 8.6m grading 5.10 g/t PdEq¹ composed of 2.22 g/t Platinum (Pt), 2.10g/t Palladium (Pd), 0.45% Copper (Cu) and 0.31% Nickel (Ni) from 151.0-159.6m downhole including 2.6m grading 9.80 g/t PdEq composed of 4.07 g/t Platinum (Pt), 4.03g/t Palladium (Pd), 0.88% Copper (Cu) and 0.65% Nickel (Ni) from 155.0m – 157.56m downhole (Figure 2).

Mineral resource endowment and palladium-equivalents are quoted pursuant to the Technical Report and Mineral Resource Estimate for the Thunder Bay North Project, Thunder Bay, Ontario, with an effective date of January 20, 2021 (the “Technical Report“). The Technical Report was posted to SEDAR March 4, 2021 and 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 core-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 Q4/2021.
