Clean Air Metals Continues to Expand High-Grade Zones at Current Deposit, Intersects 7.8m of 4.86 g/t Pt, 4.77 g/t Pd and 1.05% Cu

THUNDER BAY, ON / ACCESS Newswire / April 15, 2025 / Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSX.V:AIR)(FRA:CKU)(OTCQB:CLRMF) is pleased to announce the last results from its 2025 winter drilling program at its 100%-owned Thunder Bay North Critical Minerals Project ("TBN"). The final set of assay results, in conjunction with recent findings from the program, continue to demonstrate that the near-surface, high-grade mineralization at the Current Deposit is more extensive than previously anticipated.

Assay highlights from holes reported today:

• 16.8 m of 2.95 g/t Pt, 2.89 g/t Pd, 0.65% Cu and 0.33% Ni from 148.0 m downhole in Hole CL25-009, including

  • 4.86 g/t Pt, 4.77 g/t Pd, 1.05% Cu and 0.50% Ni over 7.8 m from 157.0 m,

• 29.1 m of 1.24 g/t Pt, 1.15 g/t Pd, 0.33% Cu and 0.26% Ni from 142.9 m downhole in Hole CL25-012, including

  • 2.76 g/t Pt, 2.63 g/t Pd, 0.59% Cu and 0.34% Ni over 4.1m from 147.0 m,

• 39.6 m of 1.29 g/t Pt, 1.19 g/t Pd, 0.29% Cu and 0.20% Ni from 104.0 m downhole in Hole CL25-007, including

  • 2.11 g/t Pt, 1.96 g/t Pd, 0.45% Cu and 0.25% Ni over 11.0 m from 116.0 m, and

  • 1.73 g/t Pt, 1.55 g/t Pd, 0.42% Cu and 0.26% Ni over 5.0 m from 133.0 m.

Mike Garbutt, CEO of Clean Air Metals, remarked, "We are pleased with the recent drill results that continue to show that Thunder Bay North has some of the thickest and highest-grade PGE-Cu-Ni sulphide mineralization in the country. We believe that there is significant potential to improve the average grade and mineability of the Current Deposit by improved definition and resource estimation of structurally-controlled higher-grade areas (‘ballrooms'). This work will assist us in developing a more robust, high-grade production model that includes both low capital intensity and toll milling optionality."
