Clean Air Metals Reports Positive Phase Two Metallurgical Test Results for the Thunder Bay North Critical Minerals Project

THUNDER BAY, ON / ACCESSWIRE / June 29, 2023 / Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV:AIR); (FRA:CKU); (OTCQB:CLRMF) announces that it has completed its follow-up metallurgical test program for the Thunder Bay North Critical Minerals Project.

The metallurgical test program consisted of locked cycle tests on a variety of composite samples with a range of head grades from both the Current and Escape deposits and delivered recoveries of 70.2% to 80.9% Platinum (Pt) and 74.0% to 86.9% Palladium (Pd) and copper recoveries from 89.9% to 96.3%. The tests were completed by Base Metallurgical Labs under the guidance of DRA Global.

Preliminary modelling of recoveries using estimated deposit head grades and updated recovery curves based on the test program, are shown in table 1 below.

CEO Comment

Jim Gallagher, CEO of Clean Air Metals stated that: "The extensive Phase 2 test program demonstrates very good recoveries of Platinum, Palladium and Copper all Critical Metals for the Green Energy revolution. In addition, there are material amounts of Nickel, Gold and Silver. These are recoverable with conventional flotation technology producing two saleable concentrates. These results will be incorporated into the ongoing optimization studies for the mine plan at Thunder Bay North."

The program followed a typical crush, grind, float flowsheet to generate an initial bulk concentrate, that was subsequently sent through a secondary flotation process to produce separate copper-rich and PGE/Nickel rich concentrates.

The test program was completed using core samples from both the Current and Escape deposits to produce 3 composites and 17 variability samples. The composites were structured to represent early and late mine life production. The composite samples and 15 of the variability samples were subjected to a combination of grindability tests including JK Drop Weight, SMC, Bond Work Index and Bond Abrasion tests.

Copper-Nickel Separation circuit

Early flowsheet assessments focused on sequential flotation to create the two concentrates. However, optimal results were achieved with bulk flotation, followed by a copper-nickel separation flowsheet which resulted in improved overall recovery of metals.

Sulphide minerals within the sample composites were sufficiently liberated at a grind size K80 of 65mm. The process included bulk flotation with rougher and cleaner stages to create a sulphide-rich product hosting PGE, chalcopyrite, pentlandite, pyrite and pyrrhotite. This product was subsequently subjected to a regrind averaging a K80 of 20mm and then subjected to a high pH float to depress nickel bearing minerals and PGEs (PGE/Ni rich conc) and float copper bearing minerals (Cu rich conc).

Consistent with previous results

The program consisted of a total of 80 open circuit development tests and 8 locked cycle flotation (LCT) tests. LCT test results highlighted the potential for the following:

  • Recoveries as high as 80.9% platinum and 86.9% palladium; and
  • Recoveries as high as 96.3% copper and up to 69.5% nickel and 84.3% gold.

The above results are encouraging and are consistent with the stated metallurgical outcomes in the previous test program undertaken by Blue Coast Research in 2021 when using similar head grades.

Preliminary 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. Through an engagement with Ocean Partners Inc., it was identified that projected concentrates produced were marketable with interest and indicative terms received from several domestic and overseas smelters.
