Clean Air Metals Confirms Potential Major
Extension at Escape Deposit Along
2.5 km Magnetic Trend
Thunder Bay, ON, September 4th, 2025 – Clean Air Metals Inc. (“Clean Air Metals” or
the “Company”) (TSX.V: AIR; FRA: CKU; OTCQB: CLRMF) is pleased to report that it has
intersected over 50 m of magmatic sulphide mineralization in the Escape ultramafic
conduit at a depth of 400 m (Image 1). The intersection was observed in core from drill
hole EL25-001, located approximately 350 m from the current limits of the Escape
Deposit (“Escape”).
The target was the first of several coincident magnetic and electromagnetic anomalies
to be drilled in the eastern half of the Escape conduit. The new intersection opens up
2.5 km of prospective geophysical targets and provides a critical new opportunity to
expand the existing mineral inventory1 in the Thunder Bay North (“TBN“) project, which
compliments the Company’s focus on advancing the project to potentially become a
significant critical minerals producer of Cu, Pt, Pd and Ni. Assay results are expected to
be available in the coming weeks.
Clean Air Metals’ Vice President of Exploration, Lionnel Djon, commented, "The success
of hole EL25-001 at Escape, which targeted a ballroom-shaped geophysical anomaly
similar to those recently drilled at the Current Deposit, is a game-changer. The hole
appears to have hit the edge of the ballroom target within the down plunge extension
of the deposit. Importantly, this new intersection validates our geophysical targeting
methodology and opens up tremendous potential for resource expansion at TBN within
the previously untested, 2.5 km long modelled eastern extension to the Escape conduit."

of the total metal content of the estimated 14 million tonnes of indicated resources (NI 43-101
technical report on the Thunder Bay North Project, Ontario, Canada, SLR Consulting Canada
Ltd, June 19, 2023) containing 2.4 million equivalent ounces of platinum.

Escape Deposit Down-Plunge Extension Drilling
In August, the Company drill-tested the first of several geophysical targets in the
modelled down-plunge extension of the Escape Deposit (see July 22, 2025, News
Release). These targets were selected within a 2.5 km-long magnetic anomaly that
locally coincides with recently defined conductivity anomalies (Figure 1).
Two other high-priority targets featuring directly coincident magnetic and conductivity
highs are planned to be drilled in future. Additional geophysical surveys are also being
considered to improve the detection of the strongest conductivity areas within the
modelled extension of the Escape conduit.
The mineralized ultramafic unit intersected in hole EL25-001 appears to represent the
side wall of the ballroom structure being targeted. A subsequent borehole EM survey
revealed a strong conductivity anomaly in the lower part of the hole, providing valuable
guidance for follow-up drilling of this specific target.

Mike Garbutt, CEO of Clean Air Metals, commented, “We couldn’t be more pleased with
what we see in this first hole drilled at the Escape down-plunge. This hole serves as a
springboard for future exploration efforts to expand the resource at Escape, while we
aggressively advance the Thunder Bay North project through upcoming studies. We are
also excited by the recent market interest in platinum and palladium, which will only
serve to further enhance the viability of this project.”
Update on Advancing the Thunder Bay North Project
The Company, in cooperation with various consultants, continues to progress the
Thunder Bay North Preliminary Economic Assessment (PEA). This study will include an
update to the resource at Current and Escape deposits, while outlining a robust, higher-
grade production model that improves toll milling potential. Results of the PEA are
expected to be available in the near future.
During the summer, the Company also collected baseline environmental data at the
project site, with a particular focus on hydrology, surface water, and hydrogeological
monitoring, in anticipation of a future permitting application. With an understanding
of the site's pre-development conditions, Clean Air Metals can evaluate risks, design
suitable mitigation measures, and establish closure plan objectives.

About Clean Air Metals
Clean Air Metals is a development and exploration company advancing its flagship,
100% owned Thunder Bay North Critical Minerals (“TBN”) project, 40 km northeast of
Thunder Bay, Ontario. The TBN project, accessible by road and next to established
infrastructure, hosts two (2) deposits - the Current and Escape deposits, only 2.5 km
apart. Together, the deposits host a 13.8 Mt indicated mineral resource containing
2.4M Pt eq. oz (Technical Report on the Thunder Bay North Project, Ontario, Canada,
NI43-101, SLR Consulting Canada Ltd, June 19, 2023) with significant potential for
expansion down-plunge.
One of the rare primary platinum resources outside of South Africa, the TBN project is
in a stable and mining-friendly jurisdiction and benefits from longstanding relationships
with local First Nations. The TBN project has the potential to develop into a secure
source of rare platinum metals, as well as other critical metals such as copper, nickel,
and cobalt, for the North American manufacturing sector. Ongoing concerns over
future platinum supply are driving prices to historic highs, with obvious benefits for a
future TBN mining operation. With its proven technical team, Clean Air Metals is
committed to growing the resources at the TBN project and creating long-term value
for shareholders.
Social Engagement
Clean Air Metals Inc. acknowledges that the Thunder Bay North Critical Minerals Project
is located within the area encompassed by the Robinson-Superior Treaty of 1850 and
includes the territories of the Fort William First Nation, Red Rock Indian Band,
Biinjitiwabik Zaaging Anishinabek and Kiashke Zaaging Anishinaabek. Clean Air Metals
also acknowledges the contributions of the Métis Nation of Ontario, Region 2 and the
Red Sky Métis Independent Nation to the rich history of our area.
The Company appreciates the opportunity to work in these territories and remains
committed to the recognition and respect of those who have lived, travelled, and
gathered on the lands since time immemorial. Clean Air Metals is committed to
stewarding Indigenous heritage and remains committed to building, fostering and
