Clean Air Metals Reports 21.4 m Grading
7.64 g/t Pt.eq in Latest Drilling Results
Thunder Bay, ON, February 27, 2025 – Clean Air Metals Inc. (“Clean Air Metals” or
the “Company”) (TSX.V: AIR; FRA: CKU; OTCQB: CLRMF) is pleased to announce the
first results from its ongoing winter drilling program at its 100%-owned Thunder Bay
North Critical Minerals Project (“TBN”). Results from the first three (3) holes confirmed
that the known areas of near-surface, high-grade mineralization at the Current deposit
are more significant than initially thought. Assay results for the remaining 10 holes are
pending and will be released when received.
Assay highlights:
• 21.4 m of 2.71 g/t Pt, 2.41 g/t Pd, 0.53% Cu and 0.28% Ni (7.64 g/t Pt.eq1;

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
2
than previously estimated. The impressive grade and significant thickness encountered
during the recent drilling programs provide additional support for establishing a more
robust, low-tonnage, 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 augment the number,
size, and grade of near-surface high-grade subzones at the Current deposit, building
on the positive results from the Summer 2024 program (see September 10, 2024,
and October 3, 2024 news releases), including:
• 51.79 m of 4.92 g/t Pt, 4.66 g/t Pd, 1.07% Cu and 0.55% Ni (14.82 g/t
Pt.eq; 4.71% Cu.eq) from 86 m downhole in Hole CL24-001;
• 31.40 m of 4.22g/t Pt, 4.04g/t Pd, 0.95% Cu and 0.56% Ni (13.04 g/t Pt.eq;
4.14% Cu.eq) from 118 m downhole in Hole CL24-003.
These new findings, in conjunction with the summer program's results, validate the
extensions of the mineralized subzones beyond 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). This further reinforces our strategy of
advancing a high-grade, high-margin moderate tonnage project.

Downhole Geophysics Program
To enhance the targeting of high-grade mineralized subzones, Clean Air Metals has
engaged Crone Geophysics to conduct downhole Electromagnetic (EM) surveys in the
Lower Current zone. This advanced program is designed to accurately identify and
target the thickest, most enriched portions of the subzones within both the Current and
Escape deposits for future drilling campaigns.
Recent analyses of historical geophysical data have revealed that downhole EM surveys
have been the most effective method for targeting high-grade mineralization at various
depths. For the upcoming downhole EM, the approach will be significantly enhanced
by employing smaller loop sizes and advanced sensor technologies specifically
designed to improve the detection of mineralized subzones, ensuring more precise
identification.
Clean Air Metals’ Vice President of Exploration, Lionnel Djon, commented, “The results
from our recent drilling at the Current deposit have provided us with increased
confidence in successfully targeting the highest-grade subzones. We’re particularly
excited by the lateral extensions of the known high-grade areas, which remain open
along strike. The systematic application of borehole EM surveys to pinpoint the position
4
of these high-grade ‘plums’ will allow us to target them downplunge to significant
depths.”

Update on Project Development Activities
After completing the winter drill program and subsequent geophysics work, the
Company will evaluate the potential to update the resource, leading to a Preliminary
Economic Assessment that details our high-grade, high-margin, low-capital
development strategy for the Thunder Bay North project.
In line with our commitment to meaningfully advance the project, Clean Air Metals has
submitted a Notice of Project Change and Project Definition Report to the Ontario
Ministry of Mines in support of an Advanced Exploration Project designation. The status
change is the first step towards obtaining permits for a potential underground ramp
and bulk sample at the Current deposit.
Upcoming Investor Event
Clean Air Metals invites shareholders and interested parties to meet with Management
and the Technical team at the upcoming PDAC convention Core Shack (#3107B) on
March 4 and 5, 2025 at the Metro Toronto Convention Centre, Toronto.
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
5
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.
