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

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

Notes

1. Platinum equivalent are calculated as follows: Pt.eq = (Pt grade/31.1035 x $976 + Pd grade x 31.1035 x 86.2% x $966 + Cu grade x 2204 x 95.9% x $4.25 + Ni grade x 2204 x 57% x 6.98 + Au grade/31.1035 x 85% x $2,939 + Ag grade/31.1035 x 65.2% x $32.89) / $976 x 31.1035

2. Copper equivalents are calculated as follows: Cu.eq= (Cu grade x 2204 x $4.25 + Pt grade x 31.1035 x 80.6% x $976 +Pd grade x 31.0135 x 86.2% x $966 + Ni grade x 2204 x 57% x $6.98 + Au grade/31.1035 x 85% x $2,9392 + Ag grade/31.1035 x 65.2% x $32.89) / $4.25 / 2204

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."
