Berliner Tageszeitung - Clean Air Metals Drilling Confirms Down-Plunge Extension of the Escape Deposit

Assay highlights from hole EL25-001:

• 53 m of 0.52 g/t Pt, 0.69 g/t Pd, 0.26% Cu and 0.17% Ni(from 404 m downhole, including

  • 0.84 g/t Pt, 1.12 g/t Pd, 0.41% Cu and 021% Ni over 22 m from 411 m, and

  • 1.08 g/t Pt, 1.41 g/t Pd, 0.52% Cu and 0.24% Ni over 11 m from 430 m, and

The results from EL25-001 confirm that drilling successfully entered the mineralized conduit system that hosts the Escape Deposit and provides a clear pathway for resource expansion down-plunge.

Mike Garbutt, CEO of Clean Air Metals, remarked, "This intercept represents a step-change in our outlook for the Escape conduit system. Hitting PGE-Cu-Ni-rich sulphide mineralization beyond the known resource envelope validates our geophysical targeting strategy. I can't understate the potential impact that the continuation of the Escape-down-plunge can have on the scale and economics of this project".

Also shown are the locations of untested magnetic and conductive anomalies distributed along the 2.5-kilometre highly prospective mineralized conduit.

Escape Deposit Down-Plunge Extension Drilling

During the summer of 2025, the Company completed its first hole (EL25-001) within the projected down-plunge extension of the Escape Deposit. The modelled extension is largely based on 3D magnetic inversion data, which show that the Escape Deposit and the extension target are part of a single, sinuous to linear magnetic anomaly sourced from altered ultramafic rocks that host the Escape Deposit. The extension also features local conductivity anomalies (Figure 1) that are of immediate interest for drilling. Drillhole EL25-001 tested one of these coincident magnetic and conductivity anomalies and, more specifically, a "ballroom"-shaped coincident anomaly analogous to the high-grade ballroom structures recently intersected at the Current Deposit (see April 15, 2025, News Release).

The hole intersected disseminated PGE-Cu-Ni-rich magmatic sulphides (up to 5% in abundance) over a 53-metre-thick gabbro-to-peridotite sequence, confirming the presence of sulphide mineralization beyond the previously modelled resource envelope (Figure 1). A borehole electromagnetic (BHEM) survey completed after drilling detected a strong off-hole conductor in the lower part of the hole, providing a clear vector for subsequent follow-up drilling.

The results from EL25-001 confirm that drilling has successfully re-entered the same mineralized conduit that hosts the Escape Deposit, as demonstrated by comparable metal ratios, tenors, and lithological characteristics. This outcome is a major technical success and provides a clear pathway for resource expansion in the down-plunge extension target.

For reference, the Escape Deposit is a key contributor to the Thunder Bay North Project, accounting for approximately 40% of the total metal content within the estimated 14.9 million tonnes of Indicated Resources (see October 9, 2025, News Release). The High-Grade Zone (HGZ) at Escape, which contains 3.1 Mt grading 3.26 g/t Pd+Pt and 1.0% Cu+Ni, occupies roughly 400 metres of the 3.5-kilometre-long Escape conduit (Figure 1). The magnetic anomaly defining the Escape down-plunge target extends a further 2.5 kilometres, highlighting the strong potential to delineate additional mineral resources along the continuation of the Escape conduit.

Clean Air Metals' Vice President of Exploration, Lionnel Djon, commented, "The first hole drilled into the extension target at Escape was a tremendous success and unlocks a huge area for future, potential resource gains for the TBN project. We can now confidently move forward with plans to fully test the 2.5 km strike length of this highly prospective target, including systematic diamond drilling guided by new surface and borehole EM surveys. "

Potential Enhancement to Recent PEA Economics

The PEA outlined an 11-year mine life, producing 8.7M tonnes of mill feed at 2,500 tonnes per day from a near-surface, ramp-access underground operation, with production shipped off-site for toll-milling. As outlined in the October 9, 2025 News Release, the project boasts a C$219.4M pre-tax NPV₈ and IRR of 39%, which expands to C$316M NPV₈ and IRR of 52%, at October 8^th, spot prices The Escape portion of the mine plan contains roughly half of the mill feed contained in the study over 1km of strike distance. The prospect of extending the Escape conduit down plunge over a similar distance would significantly increase the operational life or lead to potential throughput increases.

Next step

Building on the success of hole EL25-001, the Company plans to complete an infill Magnetotelluric (MT) survey to better define the size and position of conductive zones potentially associated with local accumulations of PGE-rich sulphide mineralization within the Ballroom structures. The results of this survey will guide a series of follow-up drill holes and borehole EM surveys within the 2.5-kilometre-long extension target.
