Clean Air Metals Identifies Potential Down Plunge Extent of Escape Intrusion and Provides a Company Update

Clean Air Metals to Host a Live, Interactive Investor Webinar

THUNDER BAY, ON / ACCESSWIRE / August 29, 2023 / Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV:AIR); (FRA:CKU); (OTCQB:CLRMF) is pleased to announce new magnetic inversion results from the Company's Thunder Bay North Critical Minerals Project near Thunder Bay, Ontario, Canada (the "Project").

The Thunder Bay North Critical Minerals Project hosts an indicated resource of 13.8Mt containing 1.2M ounces of 2PGE (Pt+Pd), 56,800 tonnes of Cu and 33,800 tonnes of Ni between the twin magmatic intrusions (chonoliths) known as the Current and Escape deposits. The Escape deposit contains 5.8Mt grading 2.6g/t 2PGE (Pt+Pd), 0.52% Cu and 0.22% Ni, as announced May 3rd, 2023. The bulk of this mineralization is hosted in the high-grade zone (HGZ) occurring in the south-eastern portion of the currently drill defined intrusion. Mineralization remains open to the southeast.

A magnetic inversion case study was executed along the trend of the Escape chonolith and the intersection of the Escape fault to the southeast, to model the potential down plunge extension of the deposit. The study was successful in identifying a volume of material with high magnetic susceptibility at depth, along the plunge of the Escape intrusion. The magnetic inversion model has an estimated top of ~650m below surface with a vertical extent of ~800m and estimated width of 500m and centred ~2000m ESE of the most eastern intersection of peridotite from the Escape drill program (ELR20-034). The entirety of this plunge potential is currently untested.

A larger geophysical inversion program using existing datasets has recently been initiated. Joint inversions of the magnetic, magnetotelluric (MT) and Z-TEM data will be completed for an area of ~80km2 which covers the Thunder Bay North Intrusive complex. The magnetic susceptibility and conductivity products from these inversions will be utilized to target the intrusions and potential mineralization hosted within at depth.

Geoff Heggie, VP Exploration commented: "The location and size of this magnetic anomaly is a logical down plunge extension of the Escape intrusion and fits with the genesis theory of these intrusions where mineral bearing magma was injected at high pressure from depth. The further refinement of this anomaly by the recently commissioned geophysical inversion program will establish the targets for the next phase of diamond drilling which is expected to commence early in 2024".

Methodology: Two magnetic inversion models were completed by EarthEX utilizing data from a 2010 ground survey and a 2008 airborne magnetic survey data. The 2008 airborne survey was completed by UTS Geophysics, utilizing a fixed wing PAC-750XL plane with three Geometrics G822A cesium vapour total field magnetometers in conjunction with a fluxgate three component vector magnetometer. The survey was carried out on 40m spaced lines and a nominal sensor height of 30m. Magnetic inversions were run on both data sets as unconstrained and generated similar results (Fig. 1) which identified a volume of material with high magnetic susceptibility at depth, along the plunge of the Escape intrusion.

Permitting

The early exploration permitting process for the next phase of exploration drilling was submitted in May 2023 and has received support from the three proximate First Nations communities upon whose traditional territory the Thunder Bay North project lies and from the two potentially affected Metis communities. The Ministry of Mines is currently consulting with one final Indigenous group and the Company expects the permits to be issued later this fall.

Receipt of Final Metallurgical Test Report

On August 22nd the Company received the final report from Base Metallurgical labs for the completed Phase Two metallurgical test program (see press release dated June 29, 2023). The test program was completed using large diameter core samples from both the Current and Escape deposits to produce 3 composites and 17 variability samples. The test program comprised a suite of 80 open circuit development tests, 8 locked cycle flotation tests and follow-up variability tests. Modelled recoveries are shown in Table 1 (below). These were generated using estimated head grades and the recovery curves derived from the Phase Two test program.

Optimal results were achieved with bulk flotation, followed by a copper-nickel separation process which resulted in a simple flowsheet and improved overall recovery of metals in two concentrates. The modelled concentrate grade outlined the potential for a clean copper concentrate grading 22% Cu, 38 g/t Pt+Pd and a PGE Ni-rich concentrate grading 50 g/t Pt+Pd and 3.75% Ni. In addition, the results of three multi-element scans of the concentrates did not identify problematic abundances of deleterious elements. A preliminary assessment of concentrate marketability was completed and identified that the projected concentrates produced, were marketable with interest and indicative terms received from several domestic and overseas smelters.

Market Commentary

With four critical metals as potentially payable in its concentrate, the Company is well positioned to take advantage of the pending metals price super cycle predicted by many analysts to supply the green energy revolution. Climate related events over the last few years have awoken the world to the effects of climate change and the need to transition away from fossil fuels as quickly as possible. Almost every major government is injecting significant financial incentives into the green energy transition. Were it not for a generally slower global economy, most significantly China's slowing economy, we would perhaps already be entering a metals price super cycle.

Of particular importance to Clean Air Metals, but not fully recognized yet by the markets, is the important role that platinum will play in the green hydrogen economy. Hydrogen is expected to be the fuel that replaces carbon-based energy in planes, ships, trains, long distance trucking and the remainder of the heavy transportation industry. In addition, steel manufacturing and other heavy industry, currently reliant on fossil fuels will have to transition to hydrogen.

The production of green hydrogen through electrolysis utilizes platinum in the electrodes to improve efficiency and resist corrosion. Likewise, hydrogen fuel cells use a platinum-based membrane to generate electricity from hydrogen. The platinum market globally is very small with only about 6 million ounces of primary production per year, almost 90% of which comes from South Africa with its inherent supply risk.

Jim Gallagher, CEO of Clean Air Metals stated: "The Thunder Bay North project remains one of the very few and very rare platinum projects outside of Africa. The project development timeline of further exploration, permitting, technical studies and project construction potentially aligns with the growth of the hydrogen economy and potential metals price appreciation. We continue to prudently manage our cash resources and still advance the Project. Equity markets in general are currently very difficult for most of the junior mining sector and the Company does not currently intend to do any dilutive financing at these low valuations. We currently have approximately $8 million in cash, sufficient to support currently planned activities well into 2024. We do continue to investigate potential strategic partners who share the Company's long-term view on the platinum market and who potentially would partner with the Company moving forward."
