THUNDER
BAY, ON, May 4, 2023 /CNW/ -
Clean Air Metals Inc. ("Clean Air Metals" or the "Company")
(TSXV: AIR) (OTCQB: CLRMF) (FRA: CKU) is pleased to announce that
further to its disclosure of February 15,
2023, the Company has completed an updated Indicated and
Inferred Mineral Resource estimate disclosed in accordance with
National Instrument 43-101 ("NI
43-101") for the Company's 100%-owned Thunder Bay North
Critical Metals Project (the
"Project").
The New Mineral Resource Estimate was prepared by SLR Consulting
Ltd. ("SLR") and is based on an underground constrained resource
model using a Net Smelter Return (NSR) cut-off value of
US$48/tonne and consensus metal
pricing (Table 3). An NI 43-101 technical report will be filed on
SEDAR within 45 days of the date of this news release.
The Current Deposit contains an Indicated Mineral
Resource of 8.2 million tonnes grading 2.7 g/t 2PGE ("Pt +
Pd"), 0.33% copper and 0.22% nickel and an Inferred Mineral
Resource of 1.6 million tonnes grading 1.7 g/tonne 2PGE, 0.32%
copper, 0.20% nickel (See Table 1; Figure 1).
The Escape
Deposit contains an Indicated Mineral
Resource of 5.8 million tonnes grading 2.6
g/t 2PGE, 0.52% copper, 0.28% nickel and an Inferred Mineral
Resource of 0.6 million tonnes grading 1.5 g/tonne 2PGE, 0.29%
copper, 0.17% nickel (See Table 1; Figure 1).
Thunder Bay North Critical Mineral Project Highlights
- Contained metal Indicated mineral resource at the Current
Deposit is 717,000 oz 2PGE, 27,000 tonnes copper, 17,700 tonnes
nickel.
- Contained metal Indicated mineral resource at the Escape
Deposit is 492,000 oz 2PGE, 30,400 tonnes copper, 16,500 tonnes
nickel.
- The underground Mineral Resources at the Current and Escape
Deposits will now be the focus of a renewed economic study which
will include specific work completed on mining run rate, optimal
sequencing of the two adjacent deposits, geotechnical analysis by
Carlisle Mine Geotech and updated metallurgical
recoveries.
- Bench scale metallurgical testing and recovery estimates are
being completed to a pre-feasibility standard by DRA Americas and
will be reported in due course.
- Rhodium and cobalt are not considered payables but are
potentially valuable by-product credits in the metals mix at
Thunder Bay North Project.
- The Current and Escape Deposits exhibit a roughly 1:1 platinum
to palladium ratio and comparable geological attributes and metal
grades.

Triple Flag Precious Metals
The Company is pleased to report that Triple Flag Precious
Metals Corp. has now forwarded the Tranche 2 payment of
C$5 million pursuant to the royalty
facility of the Thunder Bay North Project, previously reported
(Press release December 19,
2022).
Abraham Drost, CEO stated:
"The new combined Mineral Resource Estimate ("MRE") for the Escape
and Current deposits comprising the Thunder Bay North Critical
Metals Project is now complete. Work will continue to
determine viability of a potentially bulk mineable, ramp accessible
underground constrained mineral resource. Run rates, production
sequencing and preliminary economics of the new MRE are presently
being scoped internally in preparation to continue technical
studies. The Inferred mineralization suggests that the Current
and Escape deposits are open and that the underexplored remainder
of the two host magma conduits have the potential to add additional
mineral resources.
The Thunder Bay North Critical Metals Project is a potential
domestic North American source of platinum, palladium, copper and
nickel. Federal and provincial governments have placed a
strong focus on bolstering the domestic critical mineral supply
chain in North America. We are
very pleased that Triple Flag Precious Metals has completed Tranche
2 of a previously announced royalty financing to facilitate
potential development, together with our Indigenous partners, of a
sustainable critical metals mining project at Thunder Bay
North."
2023 Exploration Update
A total of 73,990 m in 171 holes
were drilled by the Company from 2020-2023 for a total
drilling database of 105,086 m in 266
holes which support the new Mineral Resource Estimate at the Escape
Deposit.
Similarly, a total of 17,172 m in
78 holes were drilled by the Company from 2020-2023 for a total
drilling database of 179,630 m in 818
holes drilled variously in 2006 – 2015 and 2020 -2023 which support
the new Mineral Resource Estimate at the Current Deposit.
Mineral Resource Estimate
Block models for the Current and Escape Deposits were created by
SLR using Seequent's Leapfrog Geo and Edge using drilling and
assays results as of April, 2023. Wireframes for the
ultramafic chonolith were generated based on logged lithologies and
chromium assays. Higher grade mineralization wireframes were
generated at a 1.0 g/t Pt + Pd cut-off grade with lower grades
included to maintain continuity. Assays were composited to
2 m lengths and were used for block
estimation on an uncapped basis. Pt, Pd, Au, Ag, Cu, Ni and
density were interpolated using Ordinary Kriging (OK) into blocks
measuring 5.0 m by 5.0 m by 2.5
m. Inverse Distance Squared (ID2) and Nearest
Neighbour estimates were run for validation purposes. Blocks
were classified following CIM Definitions (2014) as Indicated and
Inferred using drill hole spacing based criterion. Indicated
Mineral Resources were based on a nominal drill hole spacing of
50 m. Mineral Resources have
been reported within underground reporting shapes based on an NSR
cut-off value of US$48/tonne. A
crown pillar exclusion of 20 m from
the bottom of the overburden below lakes and the underground
reporting shapes used during reporting ensure that the Mineral
Resources meet the minimum requirements for Reasonable Prospects of
Eventual Economic Extraction (RPEEE).
NSR and Mineral Resources Cut-off Value
NSR values have been estimated for an operating scenario that
includes production of a split copper sulphide concentrate and a
nickel-rich residual sulphide concentrate, each containing payable
platinum and palladium, for both the Escape and Current
deposits.
Metal prices are based on consensus, long term forecasts from
banks, financial institutions, and other sources. The metal prices
and other input parameters used in development of a unit NSR value
for each block is provided in Table 3.

Previous Disclosure
In its press release of February
15th 2023, the Company disclosed that initial work on an
updated mineral resource estimate indicated the potential for a
material reduction in the total metals content of the Current
deposit in the range of 20-50%. The Company confirms that on a
comparative basis, under the new Mineral Resource Estimate, the
Current Deposit is approximately 33% lower in Indicated Pt + Pd
Contained Metal and 21% lower in Indicated Cu Contained Metal.
Management has begun the process of evaluating the potential
options and viability for development of the Thunder Bay North
project based on the new mineral resource.
Qualified Persons
The Mineral Resource estimate was prepared by,
Sean Horan, P.Geo.
(Ontario) and Tudorel Ciuculescu,
P.Geo. (Ontario), of SLR
Consulting Ltd., independent "Qualified Persons" under National
Instrument 43-101- Standards of Disclosure for Mineral Projects.
Verification included a site visit to inspect drilling, logging,
density measurement procedures and sampling procedures, and a
review of the control sample results used to assess
laboratory assay quality.
In addition, a random selection of the drill hole
database results was compared with original records.
