Clean Air Metals Withdraws Mineral Resource Estimate and PEA, Thunder Bay North Critical Minerals Project, Pending Restatement

15.02.2023  |  CNW

THUNDER BAY, Feb. 15, 2023 - Clean Air Metals Inc. ("Clean Air Metals") (the "Company") (TSXV: AIR) (OTCQB: CLRMF) (FRA: CKU) reports on an ongoing internal review of the mineral resource estimate at the Thunder Bay North Project, under the independent supervision of SLR Consulting (Canada) Ltd. ("SLR"). The Company has determined that there will likely be a material reduction in the metal content in the Current Deposit, one of the two mineral deposits comprising the Thunder Bay North Project, which could be in the range of a 20% to 50% reduction from what was previously reported by the Company.

Previous reporting was based on an independent mineral resource estimate and subsequent preliminary economic assessment ("PEA") prepared by Nordmin Engineering Ltd. (January 20, 2021; December 1, 2021; January 13, 2022). Due to an apparent over-estimation of the original mineral resource at the Current Deposit, the results of the PEA in the technical report "NI 43-101 Technical Report and Preliminary Economic Assessment for the Thunder Bay North Project, Thunder Bay, Ontario" (filed on SEDAR on January 12, 2022) must not be relied upon and the Company retracts both documents.

In July 2022, Clean Air Metals engaged SLR to provide independent oversight and validation of an updated mineral resource estimate that was to be generated for both PGE-Cu-Ni deposits (the Current and Escape deposits) within the Thunder Bay North Project (press release August 2, 2022). The process commenced with the Escape Deposit, which included the addition of approximately 38,980 m of infill drilling data in 78 holes (reported variously through 2021 and 2022) that were completed after the initial PEA cut-off date. This phase of work has upheld the tonnage and grade characteristics of the Escape Deposit. The ongoing mineral resource update work on the Escape Deposit suggests no apparent material change from the Nordmin estimate.

This was followed by the review of the large (approximately 750 drill holes) historical Current Deposit drill hole database, plus an additional 6,480 m of infill drilling in 30 holes completed by the Company after the initial PEA cut-off date. The preliminary resource model review for the Current Deposit has identified a discrepancy with the disclosed resource estimate, as stated.

More work needs to be completed before the final determination of the metal content reduction at the Current Deposit can be estimated. Additional checks on the Current mineral deposit model and mineral resource estimate will be required to estimate the expected variance and are ongoing. Updated mineral resource estimates for both the Escape and Current Deposits will be the basis for a new mineral resource technical report to be authored by SLR (the "SLR technical report").

DRA Americas continues with the metallurgical optimization work that was started in May 2022 (press release May 26, 2022). It is expected that the metallurgical test program will be completed in Q1 2023. Additional work on mill flowsheet and plant design awaits the SLR Technical Report. Similarly, mine design work anticipated by BBA Engineering (reported January 10, 2023) will be reconsidered based on the outcome of the SLR technical report.

Abraham Drost, Chief Executive Officer of Clean Air Metals, commented: "the Company commenced a normal course review of mineral resource estimates on the Escape Deposit and Current Deposit in August, 2022. The mineral resource update commenced initially on the Escape Deposit. Results from re-estimation of the mineral resource at the Escape Deposit are in line with those reported in the disclosed resource statement and PEA, at a higher level of confidence with the addition of approximately 38,980m of infill drilling in 78 holes since the initial PEA cut-off date.

Initial mineral resource update results on the Current Deposit are unexpected and disappointing. They may have a material effect on the projected economics of the Thunder Bay North Project. The outcome of the new, updated mineral resource expected for the Thunder Bay North Project will guide next steps. The Company's technical and management team together with its independent consultants are now solely focused on this important work and will update the market on a priority basis".
