Clean Air Metals Inc. (TSX-V: AIR) (FRA: CKU) (OTCQB: CLRMF) is very pleased to announce new assay results from the drilling campaign at the Escape Lake Deposit currently underway at the Company’s Thunder Bay North Project. Highlights in Table 1 and Figure 1 include:

 

  • Hole ELR21-041 intersected a massive sulphide horizon grading 7.93g/t Palladium, 6.41g/t Platinum (Pt), 4.76% Copper, 2.5% Nickel, 0.151% Cobalt over 0.5m from 337.0 – 337.5m downhole. This intercept of “loop-textured” massive sulphides (Figure 2) is located 350m north of the centroid of the Escape South High Grade Zone pod containing 2,351,310 tonnes grading 4.82g/t PdEq (reported January 20, 2021¹) The ppm metal ratios for Cu/Pt+Pd (=3300) and Ni/Pt+Pd (=1740) found in this sample closely match similar metal ratios found in the Norilsk deposits in Russia (Figure 3).
  • Hole ELR20-032 intersected 35.1m of 2.23g/t Palladium, 1.64g/t Platinum, 0.80% Copper and 0.41% Nickel from 379.0 – 414.1m downhole located in the Escape South resource area of the Escape Lake Deposit, drilled in December, 2020 and only partially reported.
  • Hole ELR21-036 intersected 20.3m of 1.21g/t Palladium, 1.01g/t Platinum, 0.43% Copper and 0.22% Nickel  from 200.8 – 221.1m downhole located between the Escape South High Grade Zone and the Steepledge North Zone.

 

Further, Hole CLM20-002 intersected 27m of 3.09g/t Palladium, 3.09g/t Platinum, 0.78% Copper  and 0.50% Nickel  from 93.1 – 120.0m downhole located in the Bridge Zone area of the Current Lake Deposit, as part of a mini bulk sample drilled with HQ core for bench test flotation metallurgical processing taking place with Blue Coast Research of British Columbia, Canada.

 

The Company has also recently completed a series of property wide geophysical transects using the magnetotelluric geophysical method. MT uses natural, low frequency electromagnetic currents to map areas of low resistivity and high conductivity in the subsurface. The survey has identified a series of high conductivity features that were not previously recognized. These are being compiled with stratigraphic and structural data into a number of high priority massive sulphide exploration targets in and around both the Escape and Current magma conduit deposit areas.

 

The inherent fertility of the Escape Lake magma conduit deposit is well illustrated by the recent mineral resource update reported on January 20, 2021 (see Footnote¹). The Escape Lake Deposit has an overall Indicated mineral resource of 505,369 ounces at 3.67g/t PdEq in 4,286,220 tonnes and is geologically open along trend. With the 2020 investment of CAD$4.5 million into 19,000m of drilling at Escape in 2020, the average cost of discovery and compiling historical drill results was approximately $9.00 per Indicated ounce PdEq.

Abraham Drost, CEO of Clean Air Metals stated that “the discovery of Norilsk-style Ni-Cu-Co massive sulphides with substantial Pt and Pd in the Escape Lake Deposit system is a potential game changer for the Company. Early on we recognized the high-level similarities of the magma conduit chonolith system and structural and stratigraphic controls on mineralization at Thunder Bay North with the Talnakh complex at Norilsk, one of the world’s foremost Nickel-Copper-PGM deposits. Based on the new discovery of massive sulphides in the Escape Lake Deposit with favorable metal ratios and the recent completion of a structural analysis and MT geophysical surveys, we are well funded to ramp up our exploration efforts in both the Escape Lake and Current Lake magma conduit deposit systems.”

 

The Company plans a minimum 30,000m of further delineation drilling at the Escape Lake Deposit at a cost of approximately $6.6 million in 2021. The Current Lake Deposit, itself with an Indicated mineral resource of 1,328,789 oz PdEq at an average grade of 3.44 g/t PdEq in 11,999,177 tonnes (reported January 20, 2021; see Page 1 Footnote¹) will also receive additional $2.2 million budget for approximately 10,000m of drilling to convert Inferred into Indicated in the Beaver Lake Zone area.

 

A further minimum $1.1 million program of 5000m drilling will be allocated to drilling specific structural/stratigraphic targets both inside and outside the known magma conduit areas, with coincident high conductivity MT geophysical anomalies and high prospectivity for massive sulphide mineralization.

COVID Policy

 

Clean Air Metals has adopted COVID-19 avoidance and personal protection measures for its geological staff, drilling contractor and service suppliers. Personnel are required to maintain physical distance, use Personal Protective Equipment (PPE), self-monitor and self-isolate or elect to work from home. Management had previously eliminated plans for a camp setup to service a planned diamond drill campaign on the Escape Lake Project. The Company is aware of Thunder Bay Health Unit guidelines that provide for “mandatory” self-isolation for returning overseas travel. The guidelines also “strongly recommend” self- monitoring and self-isolation as needed after travel into the Northwest region from other areas of the Province and interprovincially. Mineral Exploration and Development has been deemed an essential service in the Province of Ontario (http://www.netnewsledger.com/2020/03/23/ontario-covid-19-business-allowed-to-remain-open-list-march-23-2020/ ). The Company has procured the services of a locally staffed and serviced diamond drilling contractor to complete the diamond drilling program.
