Clean Air Metals to Drill the Escape Deposit

Down-Plunge Target

Thunder Bay, ON, July 22, 2025 – Clean Air Metals Inc. (“Clean Air Metals” or the

“Company”) (TSX.V: AIR; FRA: CKU; OTCQB: CLRMF) is pleased to announce its

upcoming 2025 summer drilling program aimed at testing the interpreted down-

plunge extension of the Escape Deposit at its 100%-owned Thunder Bay North Critical

Minerals Project (“TBN”). An initial 900-m hole, targeting one of three newly identified

‘ballroom-type’ coincident magnetic and conductivity anomalies, will commence this

week. The program is designed to be scalable depending on results.

Escape Deposit Down-Plunge Extension Target

The Escape Deposit (“Escape”) is a key contributor to the Thunder Bay North (“TBN”)

Project, representing approximately 40% 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.

The Escape down-plunge extension target (Figure 1) is believed to have the best

potential for a major resource expansion within the Thunder Bay North project. The

Company has been working on improving the target definition in this area since 2023,

starting with the identification of a large untested magnetic anomaly that extends from

the known Escape high-grade zone to a distance of 2.5 km (see August 29, 2023, News

Release).

conduits as determined from drilling. The Escape grid with seismic sensors is shown in

In the spring of 2025, the Company engaged an expert in Magnetotelluric (MT)

geophysical surveys to reassess historical MT data for the extension target. The

assessment identified three coincident magnetic and EM anomalies (Figure 2) that have

strongly similar characteristics to the recently drill-confirmed high-grade ‘ballroom’

mineralization at the Current Deposit (see October 3, 2024 and April 15, 2025 News

Releases). It also clearly identified the known mineralization at the Escape High-Grade

zone, which provides additional confidence in these three targets.

Deposit.

The initial drill hole and borehole EM survey is planned to test target BH 25-01 (Figure

3). This target coincides with the borehole EM anomalies identified from historical drill

holes in this area. In addition, it lies ~300 metres to the east of the easternmost, drill-

defined extent of the Escape Deposit that hosts the Escape High-Grade Zone.

Highlights of the high-grade results disclosed in the October 29, 2020, News Release

include:

• 98.9 m grading 1.89g/t Pd, 1.40g/t Pt, 0.69% Cu and 0.35% Ni from 324.4 m

downhole in hole ELR20-025, including 19.2 m of 4.09g/t Pd, 2.90g/t Pt, 1.42%

Cu and 0.75% Ni from 392.5 m;

• 39.2 m grading 2.61 g/t Pd, 1.94 g/t Pt, 0.99% Cu and 0.61% Ni from 395.0 m

downhole in hole ELR20-028, including 21.70 m of 3.70g/t Pd, 2.69g/t Pt, 1.40%

Cu and 0.89% Ni from 398.1 m;

• 96.0 m grading 1.63 g/t Pd, 1.22g/t Pt, 0.61% Cu and 0.34% Ni from 326.8 m

downhole in hole ELR20-008, including 18.0 m of 3.20g/t Pd, 2.29g/t Pt, 1.17%

Cu and 0.76% Ni from 391.8 m.

Clean Air Metals’ Vice President of Exploration, Lionnel Djon, commented. "The new

geophysical assessments have delivered very appealing ‘ballroom-type’ drill targets in

the Escape down-plunge extension area. We are excited to begin drill testing these

targets that collectively represent the best opportunity for a significant expansion of the

high-grade Thunder Bay North Pt-Pd-Cu-Ni sulphide mineralization."

Update on Advancing the Thunder Bay North Project

The Company continues to work on a Preliminary Economic Assessment on the

Thunder Bay North Project. This study is driven in part by the successful drilling

programs in 2024 and early 2025, which expanded high-grade ballrooms at the Current

5

Deposit, and provides confidence in the development of a robust, higher-grade

production model that improves toll milling potential. The company has also increased

activity on baseline environmental monitoring at the site, which will be critical to

obtaining a permit for advanced exploration.

Mike Garbutt, CEO of Clean Air Metals, remarked, "The identification of geophysically-

constrained drill-ready targets in the Escape down-plunge extension is an important

breakthrough for the Company and gives us a tangible path forward to expanding the

highest-grade components of the existing TBN global mineral resource. At a time that

the broader market has realized the investment appeal of the PGEs, reflected in the

recent appreciation in both platinum and palladium prices, we are excited to continue

exploration for high-grade mineralization at Escape and to commence work on a new

PEA study focusing on the higher-grade parts of both the Escape and Current deposits."
