CLEAN AIR METALS REPORTS DRILLING UPDATE FROM THE THUNDER BAY NORTH PROJECT, THUNDER BAY, ONTARIO
Clean Air Metals Inc. has released new assay results from the drilling campaign presently under way at the company's Thunder Bay North 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.

Abraham Drost, CEO of Clean Air Metals stated that "the present round of assay results from the Current deposit ("CL" holes) confirm continuity of mineralization between sections along the trend of mineralization, at the Lower Bridge and Upper Beaver Lake Zones. Earlier assays from this round of drilling at the Current Deposit have already been incorporated into a mean stope optimizer (MSO) mine planning algorithm for the upcoming PEA.
The results from highlight Hole ELR21-085 in the Escape Deposit ("ELR" holes) appear to demonstrate increasing grade on the eastern edge of the historic Steepledge South resource area, 700m north of the Escape South High-Grade Zone. The drilling plan for Steepledge South is coming into prominence here with 20+ holes laid out for completion in Q4 and possibly into 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. 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 (https://www.netnewsledger.com/2020/03/23/ontario-covid-19-business-allowed-to-remain-open-list-march-23-2020/ ).
Qualified Person
Dr. Geoff Heggie, Ph.D., P.Geo., a Qualified Person under National Instrument 43-101 and Exploration Manager for the Company, has reviewed and approved all technical information in this press release.
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 Metals' 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 Metals 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.
Social Engagement
Clean Air Metals Inc. and its wholly-owned subsidiary Panoramic PGMs (Canada) Ltd. acknowledge that the Thunder Bay North Project is on the traditional territories of the Fort William First Nation, Red Rock First Nation and Biinjitiwabik Zaaging Anishinabek. The parties together are the Cooperating Participants in a Memorandum of Agreement dated January 9, 2021.
About Clean Air Metals Inc.
Clean Air Metals' flagship asset is the 100% owned, high grade Thunder Bay North Project, a platinum, palladium, copper, nickel project located near the City of Thunder Bay, Ontario and the Lac des Iles Mine owned by Impala Platinum. The Clean Air Metals project hosts the Current Deposit and magma conduit and the Company is actively exploring the Escape Deposit, a twin structure to the Current Deposit. Executive Chairman Jim Gallagher and CEO Abraham Drost lead an experienced team of geologists and engineers who are using the Noril'sk magma conduit stratigraphic and mineral deposit model to guide ongoing exploration and development studies. As the former CEO of North American Palladium Ltd. which owned the Lac des Iles Mine prior to the sale to Impala Platinum in December 2019, Jim Gallagher and team are credited with the mine turnaround and creation of significant value for shareholders.
