March 3, 2023 Clean Air Metals Presents Update on Mineral Resource Estimation Process at Current Deposit, Thunder Bay North Project THUNDER BAY, ON, March 3, 2023 /CNW/ - Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV: AIR) (OTCQB: CLRMF) (FRA: CKU), is pleased to provide an update on the preparation of a new mineral resource estimate at the Thunder Bay North Project by SLR Consulting (Canada) Ltd. ("SLR") (see press release dated February 15, 2023). The Company continues to work with SLR Consulting, with the cooperation of Nordmin Engineering, to determine the nature, cause, and extent of the discrepancy, if confirmed, as outlined in the Company's February 15, 2023, news release. This work includes a review of the Company's geological framework, as well as modeling approaches, mineralogy, geochemistry and mineral assemblages employed as controls on mineralization in preparing the geological interpretation. SLR has also been commissioned by the Company, at the completion of this review, to complete a full and independent mineral resource update of the Thunder Bay North project which includes both the Current and Escape deposits. Review work for the Escape deposit, which has had over 38,000 metres of additional infill drilling since the previous mineral resource estimate was published, do not suggest a discrepancy in metal content. It should be further noted that Todd McCracken, P.Geo Director – Mine and Geology at BBA E&C Inc. and a recognized expert in resource estimation, has been appointed as an owner representative to the Company to assist senior management and the board of directors with the technical issues under review.
