CLEAN AIR METALS REPORTS DRILLING UPDATE FROM THE THUNDER BAY NORTH PROJECT AND APPOINTMENT OF DR. GEOFF HEGGIE AS EXPLORATION MANAGER
Clean Air Metals Inc. has appointed Dr. Geoff Heggie, PGeo, as exploration manager and a qualified person for the company's Thunder Bay North project. Dr. Heggie replaces Mr. Allan MacTavish, M.Sc., P.Geo. who has retired from fulltime duties as Vice President, Project Manager, and will continue with the Company in a non-executive consulting capacity.
Dr. Heggie worked on the Thunder Bay North Project previously for 7 years. He earned his BSc in Geology at the University of Saskatchewan, his MSc at Lakehead University and his PhD at the University of Western Australia. Most recently with Noront Resources, Geoff is an expert in Ultramafic/Mafic magmatic systems. Previously as Senior Geologist at Noront, systematic integration of geology and geophysics by the Noront team was typified by the discovery of the McFaulds No. 8 VMS lenses of the Nikka deposit during Geoff's tenure.
New assay results are from the drilling campaign presently underway at the Company's Thunder Bay North Project (the "Project"). Assay highlights (from Table 1) include:
- Hole ELR21-079 from the Escape Lake Deposit (Figure 1) which intersected 21.3m grading 4.80g/t Palladium Equivalents (PdEq) 1 composed of 1.64g/t Platinum (Pt), 1.97g/t Palladium (Pd), 0.66% Copper (Cu), 0.23% Nickel (Ni) from 388.7m-410.0m downhole including 7.5m grading 6.80g/t PdEq composed of 2.46 g/t Platinum (Pt), 2.94g/t Palladium (Pd), 0.96% Copper (Cu), 0.26% Nickel (Ni) from 400.5m-408.0m downhole (Figure 1).
The Escape Lake Deposit has undergone systematic expansion drilling exceeding 27,000m 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 Lake 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) and is currently well advanced with a Preliminary Economic Assessment (PEA) study to be published in Q4-2021. The PEA-level mine stope optimization in the Beaver Lake Zone area of the Current Lake Deposit maybe enhanced by the results of a recent infill drill program, including the following highlight results:
- Hole CL21-014 which intersected 18.0m grading 3.10 g/t PdEq1 composed of 1.36 g/t Platinum (Pt), 1.28g/t Palladium (Pd), 0.24% Copper (Cu) and 0.20% Nickel (Ni) from 127.5 {ᒞ –} 145.5m downhole including 5.10m grading 5.90 g/t PdEq composed of 2.77 g/t Platinum (Pt), 2.72g/t Palladium (Pd), 0.43% Copper (Cu) and 0.28% Nickel (Ni) from 140.4m {ᖾ –} 145.5m downhole
- Hole CL21-015 which intersected 12.0m grading 7.90 g/t PdEq1 composed of 3.67 g/t Platinum (Pt), 3.31g/t Palladium (Pd), 0.75% Copper (Cu) and 0.38% Nickel (Ni) from 144.0 {ᛴ –} 156.0m downhole including 8.0m grading 10.4 g/t PdEq composed of 4.92 g/t Platinum (Pt), 4.45g/t Palladium (Pd), 0.98% Copper (Cu) and 0.46% Nickel (Ni) from 144.0m {᠓ –} 152.0m downhole
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 early Q4/2021.
Abraham Drost, CEO of Clean Air Metals stated that "we are very pleased to welcome Dr. Geoff Heggie to the Clean Air Metals team. Geoff's prior experience at the Thunder Bay North Project with predecessor companies and his innate expertise in magmatic systems gained in a variety of geological settings is accretive to the team. We look forward with Geoff and team to unlocking the full potential of the Escape and Current chonolith deposits and locating the source of high-grade massive sulphide occurrences within the system.
We are grateful to Al MacTavish for his 14-year tenure with the Project and his considerable contributions from early discovery to present. We are pleased that, although stepping back to enjoy time with family and lead geology field trips to exotic locales like Iceland and Hawaii, Al has agreed to continue on a consulting basis to work on geological studies relevant to exploration of the Thunder Bay North Project.
The Company is looking forward to publication of a PEA in Q4/21. 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 scale to the Thunder Bay North Project with future feed from the Escape Lake Deposit is potentially accretive to the project."

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 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.
