Clean Air intersects sulphide mineralization at Escape

Mr. Mike Garbutt reports CLEAN AIR METALS CONFIRMS POTENTIAL MAJOR EXTENSION AT ESCAPE DEPOSIT ALONG 2.5 KM MAGNETIC TREND Clean Air Metals Inc. has intersected over 50 metres of magmatic sulphide mineralization in the Escape ultramafic conduit at a depth of 400 metres. The intersection was observed in core from drill hole EL25-001, located approximately 350 m from the current limits of the Escape deposit. 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 kilometres of prospective geophysical targets and provides a critical new opportunity to expand the existing mineral inventory1 in the Thunder Bay North project, which complements the company's focus on advancing the project to potentially become a significant critical mineral producer of copper, platinum, palladium and nickel. 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-kilometre-long modelled eastern extension to the Escape conduit." 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-kilometre-long magnetic anomaly that locally coincides with recently defined conductivity anomalies. 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 electromagnetic 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, chief executive officer 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 co-operation with various consultants, continues to progress the Thunder Bay North preliminary economic assessment. This study will include an update to the resource at the 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 predevelopment conditions, Clean Air Metals can evaluate risks, design suitable mitigation measures and establish closure plan objectives. Qualified person Dr. Lionnel Djon, PhD, PGeo, a qualified person under National Instrument 43-101, vice-president of exploration for the company, has reviewed and approved all technical information in this press release. About Clean Air Metals Inc. Clean Air Metals is a development and exploration company advancing its flagship, 100-per-cent-owned Thunder Bay North critical mineral project, 40 km northeast of Thunder Bay, Ont. The TBN project, accessible by road and next to established infrastructure, hosts two deposits: the Current and Escape deposits, only 2.5 km apart. Together, the deposits host a 13.8-million-tonne indicated mineral resource containing 2.4 million ounces platinum equivalent (technical report on the Thunder Bay North project, Ontario, Canada, National Instrument 43-101, 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 long-standing 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. Continuing 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 expanding the resources at the TBN project and creating long-term value for shareholders. Social engagement Clean Air Metals acknowledges that the Thunder Bay North critical mineral 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 Metis Nation of Ontario, Region 2, and the Red Sky Metis 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 encouraging a respectful relationship with first nations, Metis and Inuit peoples based upon principles of mutual trust, respect, reciprocity and collaboration in the spirit of reconciliation. We seek Safe Harbor.
