Clean Air Metals Intersects 41.0m Grading 13.2 g/t Pt.eq at the Current Project

March 04, 2025 at 08:12 AM EST

THUNDER BAY, ON / ACCESS Newswire / March 4, 2025 / Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV:AIR)(FRA:CKU)(OTCQB:CLRMF) is pleased to announce the latest results from its ongoing winter drilling program at its 100%-owned Thunder Bay North Critical Minerals Project ("TBN"). The second set of assay results has confirmed that the near-surface, high-grade mineralization at the Current deposit is more extensive and significant than previously anticipated. Notably, one hole intersected 41.0 meters grading 13.2 g/t Pt.eq including 10.0 meters with 1.57% Cu and 22.39 g/t Pt.eq. The newly modeled shape of this high-grade area strongly resembles the "Ballroom" structures associated with the JM Reef in the Stillwater Complex in Montana. The high-grade zone intersected in hole CL25-005 and in several adjacent high-grade areas remains open laterally and at depth, significantly enhancing the exploration potential at the Current deposit.Assay results for the remaining seven holes are pending and will be released once received.

Assay highlights:

41.0 m of 4.52 g/t Pt, 4.29 g/t Pd, 0.97% Cu and 0.52% Ni(13.20 g/t Pt.eq¹; 4.42% Cu.eq²) from 110 m downhole in Hole CL25-005, including
- 5.75 g/t Pt, 5.37 g/t Pd, 1.18% Cu and 0.61% Ni (16.42 g/t Pt.eq¹; 5.50% Cu.eq²) over 28.0m from 121.0 m, and
- 7.87 g/t Pt, 7.34 g/t Pd, 1.57% Cu and 0.90% Ni (22.39 g/t Pt.eq¹ ; 7.50% Cu.eq²) over 10.0 m from 138.0 m
- 12.08 g/t Pt, 10.87 g/t Pd, 2.38% Cu and 1.05% Ni (33.30 g/t Pt.eq¹ ; 11.16% Cu.eq²) over 2.0 m from 146.0 m

Equivalents are based on the following recoveries Pt 80.6%, Pd 86.2%, Cu 95.9% Ni 57%, Au 85%, Ag 65.2%; and metal prices from February 20, 2025, US Spot; Pt $976, Pd $966, Cu $4.25, Ni $6.98, Au $2939, Ag $32.89

Mike Garbutt, CEO of Clean Air Metals, remarked, "These latest results have validated our belief that the Current deposit hosts more near-surface high-grade mineralization than previously estimated. The impressive grade and significant thickness encountered during the recent drilling programs provide additional support for establishing a more robust, high-grade production model. These results have also highlighted the critical importance of leveraging downhole geophysics to locate the highest-value mineralization targets at Current and Escape as we continue to advance the Thunder Bay North Project."

The Winter 2025 drilling program is strategically designed to increase the size, number, and grade of near-surface high-grade areas at the Current deposit, building on the strong results from the Summer 2024 program. The latest findings, in conjunction with earlier data, further validate the extension of mineralized zones beyond the scope of the most recent resource model (NI 43-101 technical report on the Thunder Bay North Project, Ontario, Canada, SLR Consulting Canada Ltd, June 19, 2023).

Unlike previous drilling, this hole intersected a high-grade zone carved into the footwall of the deposit, indicating a more expansive distribution of mineralization than is presently modeled. This result significantly alters the interpretation of the Current deposit, as it suggests that areas previously considered outside the core mineralized body may also host high-grade mineralization much like the irregular, high-concentration zones seen in the "ballrooms" below the JM Reef of the Stillwater Complex in Montana.

This discovery is pivotal for resource estimation, as it changes the parameters that will be used to estimate the sulfide-rich, high-grade zones. The new understanding of mineralization extending into the footwall and beyond the limits of previous models calls for a reassessment of the resource potential, particularly in terms of accurately capturing the extent of these higher-grade zones.

Furthermore, the potential for additional high-grade subzones in the region is significant. With continued drilling and an increased density of borehole electromagnetic (BHEM) surveys, we expect to identify new areas where mineralization could mirror the high-grade characteristics observed in CL25-005. Increasing drill density and utilizing BHEM to guide future drill targets will be essential to fully unlocking the high-grade potential of the Current and Escape deposits and identifying similar subzones that may have been missed by earlier exploration.

Clean Air Metals' Vice President of Exploration, Lionnel Djon, commented, "The extension of high-grade mineralization into the footwall in hole CL25-005, combined with the fact that it remains open to the southwest, highlight the clear opportunity to increase the percentage of high-grade resource at Current. Drawing on the ballroom analogy, we will continue to target thick and high-grade mineralization in and below the existing mineralized shell. The use of BHEM surveys will be a critical tool in guiding our next phase of drilling, allowing us to identify new conductive targets and better define the full extent of the high-grade areas."

Qualified Person

Dr. Lionnel Djon, Ph.D., P.Geo., a Qualified Person under National Instrument 43-101 and Vice President of Exploration 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 cores are cut with a diamond-tipped saw blade, and half are submitted to ALS for sample preparation and analysis. Sample preparation is completed at the ALS sample preparation facility in Thunder Bay, ON, and analysis is completed at the primary ALS assay laboratory in Vancouver, B.C.

Clean Air Metals follows a quality control procedure for its core assay sampling program: inserting blind blanks and certified Palladium-Platinum and Copper-Nickel standards into the sample stream. The insertion procedure follows industry standards with 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 optical emission spectroscopy (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 assay method with an ICP finish.
