Clean Air Metals expecting PEA on Thunder Bay North this quarter

Nov 20, 2021

By Kevin Vincent
One of the busiest companies in northwestern Ontario is a junior, Clean Air Metals. Clean Air’s flagship asset is the 100% owned, high grade Thunder Bay North Project, a platinum, palladium, copper, nickel property located near the Lac des Iles Mine owned by Impala Canada.
The Clean Air Metals project hosts the Current Lake deposit and magma conduit, and the company is actively exploring the Escape Lake deposit, a twin structure to the Current Lake deposit.
Executive Chairman Jim Gallagher and CEO Abraham Drost lead an experienced team of geologists and engineers who are using the Norilsk magma conduit stratigraphic and mineral deposit model to guide ongoing exploration and development studies.
The company recently announced the appointment of Dr. Geoff Heggie, P.Geo. as Exploration Manager and a Qualified Person for the Company’s Thunder Bay North Project.
“We are very pleased to welcome Dr. Geoff Heggie to the Clean Air Metals team,” said Abraham Drost, CEO of Clean Air Metals. “Geoff’s prior experience at the Thunder Bay North Project with predecessor companies and his innate expertise in magmatic systems gained in a variety of geological settings is accretive to the team. We look forward with Geoff and team to unlocking the full potential of the Escape and Current chonolith deposits and locating the source of high-grade massive sulphide occurrences within the system.
We are grateful to Al MacTavish for his 14-year tenure with the Project and his considerable contributions from early discovery to present. We are pleased that, although stepping back to enjoy time with family and lead geology field trips to exotic locales like Iceland and Hawaii, Al has agreed to continue on a consulting basis to work on geological studies relevant to exploration of the Thunder Bay North Project.”
Dr. Heggie worked on the Thunder Bay North Project previously for seven years. He earned his BSc in Geology at the University of Saskatchewan, his MSc at Lakehead University and his PhD at the University of Western Australia. Most recently with Noront Resources, Geoff is an expert in Ultramafic/Mafic magmatic systems. Previously as Senior Geologist at Noront, systematic integration of geology and geophysics by the Noront team was typified by the discovery of the McFaulds No. 8 VMS lenses of the Nikka deposit during Geoff’s tenure.

New assay results are from the drilling campaign presently underway at the company’s Thunder Bay North Project.

Assay highlights include:

Hole ELR21-079 from the Escape Lake Deposit which intersected 21.3m grading 4.80g/t Palladium Equivalents (PdEq)1 composed of 1.64g/t Platinum (Pt), 1.97g/t Palladium (Pd), 0.66% Copper (Cu), 0.23% Nickel (Ni) from 388.7m-410.0m downhole including 7.5m grading 6.80g/t PdEq composed of 2.46 g/t Platinum (Pt), 2.94g/t Palladium (Pd), 0.96% Copper (Cu), 0.26% Nickel (Ni) from 400.5m-408.0m downhole.

The Escape Lake Deposit has undergone systematic expansion drilling exceeding 27,000m since the maiden Indicated resource of 505,369 ounces PdEq1 (3.67 g/t PdEq in 4.28 million tonnes reported January 20, 2021).
The Current Lake Deposit 2.5km to the east has a well-defined Indicated mineral resource of 1,328,789 PdEq1 ounces (3.44 g/t PdEq in 11.99 million tonnes) and is currently well advanced with a Preliminary Economic Assessment (PEA) study to be published in Q4-2021. The PEA-level mine stope optimization in the Beaver Lake Zone area of the Current Lake Deposit may be enhanced by the results of a recent infill drill program, including the following highlight results:
+ Hole CL21-014 which intersected 18.0m grading 3.10 g/t PdEq1 composed of 1.36 g/t Platinum (Pt), 1.28g/t Palladium (Pd), 0.24% Copper (Cu) and 0.20% Nickel (Ni) from 127.5 – 145.5m downhole including 5.10m grading 5.90 g/t PdEq composed of 2.77 g/t Platinum (Pt), 2.72g/t Palladium (Pd), 0.43% Copper (Cu) and 0.28% Nickel (Ni) from 140.4m – 145.5m downhole
+ Hole CL21-015 which intersected 12.0m grading 7.90 g/t PdEq1 composed of 3.67 g/t Platinum (Pt), 3.31g/t Palladium (Pd), 0.75% Copper (Cu) and 0.38% Nickel (Ni) from 144.0 – 156.0m downhole including 8.0m grading 10.4 g/t PdEq composed of 4.92 g/t Platinum (Pt), 4.45g/t Palladium (Pd), 0.98% Copper (Cu) and 0.46% Nickel (Ni) from 144.0m – 152.0m downhole

Update on Metallurgy and PEA

Metallurgical optimization studies continue with Blue Coast Research of British Columbia. The results of the metallurgical studies on drill core-derived bulk sample material and independent analysis of smelter recoveries and smelter payables are expected to input directly into a Preliminary Economic Assessment (PEA) mine cash flow model planned for publication in early Q4/2021.
As with the mineral resource estimate published in March 2021, the PEA will be based on a ramp-access underground mine model constraining the existing mineral resource. In addition to the Current Lake Deposit, the potential to add scale to the Thunder Bay North Project with future feed from the Escape Lake Deposit is potentially accretive to the project.”

Clean Air Metals, Dr. Geoff Heggie PhD., P.Geo, Exploration Manager for the company will be speaking at the Mining the Northwest Virtual Conference on November 30th.
