Clean Air Metals Intersects 41.0m Grading 13.2
g/t Pt.eq at the Current Project
Thunder Bay, ON, March 4, 2025 – Clean Air Metals Inc. (“Clean Air Metals” or the
“Company”) (TSX.V: 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
o 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
o 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
o 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

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.

at the Current deposit.
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.”

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
6
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.
