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, 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
o 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
o 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
o 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
o 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.”

A Closer Look at the 2025 Winter Drilling Program:
The Winter 2025 drilling program was designed to increase the size, number, and
grade of the near-surface high-grade mineralization within the Lower Current and
Bridge zones. Out of the 13 holes drilled, eight intersected significant widths of high-
grade mineralization, averaging over 3 g/t Pt+Pd (Table 1). This supports the view that
the high-grade zones at the Current Deposit are larger and more extensive than
previously modeled (Figure 1).
In the Bridge Zone, tighter drilling successfully expanded a flat-lying high-grade
mineralization target, with grades matching or surpassing those predicted in the current
resource estimate. This area demonstrates significant potential for further resource
growth.
In the Lower Current Zone, historical and recent drilling shows that the highest-grade
mineralization is concentrated in embayment structures developed at the base of the
tubular-shaped host intrusion. These structures can extend for up to several tens of
metres below the average position of the basal contact and resemble the "ballroom"
structures seen in the JM reef in the Stillwater Complex, Montana. They represent a key
to improving the average grade for the Current Deposit (Figure 2).

Drilling Program at the Current Deposit.

Clean Air Metals’ Vice President of Exploration, Lionnel Djon, commented, “The winter
drilling program clearly demonstrates the potential of the Current Deposit to host near-
surface, high-grade zones beyond previously defined boundaries, highlighting a strong
opportunity for expansion of the highest-grade parts of the deposit. What’s particularly
exciting is that the recent high-grade expansion drilling has covered only ~20% of the
known strike length of the Current Intrusion, leaving substantial potential for expanding
the number and size of high-grade areas in the deposit.”

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.
6
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.
