Canadian North Resources Inc. (“Canadian North” or the “Company”)
(TSXV: CNRI; OTCQX: CNRSF; FSE: EO0 (E-O-zero)) is pleased to
report the start of a new and extensive metallurgical program
following the successful technical evaluation of bioleaching
technology for the Ferguson Lake copper, nickel, cobalt, palladium
and platinum project (“the Ferguson Lake Project”).
“Highly encouraged by the exceptional results of
the bio-leaching tests completed in 2024,” said Dr. Kaihui Yang,
President and CEO of the Company, “We are expanding the
bio-leaching tests to develop a mineral processing flowsheet for
the high recovery of nickel, cobalt, copper and PGE. When proven,
this flowsheet will simplify mineral processing, bypassing smelting
and metal refining, and it will substantially reduce the capital
expenditures needed for mine development, energy consumption, and
operating cost for production. We believe that bio-leaching is a
promising technology for developing a low-cost, low-carbon
footprint green mine at the Ferguson Lake project.”
Previous results from bio-leaching amenability
tests held during summer and fall 2024 indicate that both the
massive sulphides and the rougher sulphide tail are amenable to
bio-leaching with very high extraction rates for nickel
(97.8-98.9%) and cobalt (96.0-97.7%) (Table 1) plus encouraging
initial extractions of Cu of 73.6 -75.4% from massive sulphides. It
is believed that the Cu extraction rate can be significantly
improved with additional testing. (Refer to the Company’s Press
Release dated on October 21, 2024)

Table 1: Initial bio-leaching test results for
the two samples from the Ferguson Lake project
The Company has chosen to continue working with
its scientific partner, RPC at its laboratory in Fredericton, New
Brunswick, to further advance and evaluate various applications of
bio-leaching technology for the Ferguson Lake project since early
May 2024. The new bio-leaching tests will be carried out on a 100kg
massive sulphide sample collected from outcrop in the Central Zone.
For these tests RPC uses indigenous bacteria cultivated from the
massive sulphide out collected at surface of outcrop and in water
samples. The new bio-leaching program consists of a two-phased
approach over the course of 2025 with the goal of achieving
multiple milestones.
Phase 1: Continued extensive bio-leaching metal
testing for the extractions of Ni, Co and Cu. This first phase of
the program will focus on testing various conditions for whole ore
bio-leaching treatment as the Ferguson Lake massive sulphide is
highly amenable to such process. Various processing methods will be
used to establish leach extraction rates. Testing will include
various ore and grind sizes up to ¾ inch sized crushed massive
sulphides to evaluate effect of crush size. The extracted
bio-leaching solution from semi-continuous testing will be put
through scoping precipitation tests to better understand the
mobility of various metals under controlled conditions. RPC will
then design a new conceptual flowsheet by incorporating the optimal
operating conditions found, process flowsheets, operating
conditions, and reagent consumptions where possible.
Phase 2 of the metallurgical program will
evaluate various metal recovery options from the pregnant
bio-leaching solution and the residual product. These tests will
focus on recovering copper metal, nickel and cobalt as metals
and/or Mixed Hydroxide Precipitate (MHP) and as battery grade
sulphates, PGE metals as well as other valuable metals (e.g. gold,
silver) and by products. The tests will also include the removal of
impurities and treatment of tailings.
The extremely high nickel and cobalt and
encouraging copper extraction rates from bio-leaching tests in 2024
suggests the possibility of the successful recovery of nickel,
cobalt and copper from the current mineral resources of the
Ferguson Lake project. The latest resource estimation, filed on May
3, 2024, was based on the metal recoveries (29-51% Ni, 48-89% Co,
78-95% Cu, 60-76% Pd, 60-70% Pt) of the flotation process on
massive sulphides (MS) and PGM-enriched low sulphide (LSPGE)
materials. Bio-leaching, with its much higher metal extraction
capabilities, will substantially increase the value of the current
mineral resources and potentially allow the Company to add
substantial lower-grade mineralized materials as economic mineral
resources. Ongoing Ni-Cu-Co-Pd-Pt flotation-gravity testing
continues in parallel with the bio-leaching test program.
About RPC and bio-leaching
technology:
RPC is a respected research and technology
organization providing specialized engineering, scientific and
laboratory-based services, based in New Brunswick, Canada. RPC’s
engineers and scientists are supported by world-class analytical
chemistry, air quality and material-testing laboratories and a wide
variety of pilot facilities for the development and improvement of
industrial and environmental processes and products.
Bio-leaching is a proven technology that uses
naturally occurring oxidizing bacteria to extract nickel, cobalt,
copper and precious metals from sulfides. Operating at low
temperatures with minimal power consumption, this low-cost, clean
technology is a more environmentally friendly alternative than
high-temperature and pressure processing methods such as
hydrometallurgy, smelting and refining. While bio-leaching has been
applied in mines worldwide, not all of ores are amenable to this
process, and metal extraction can vary significantly depending on
ore mineralogy.
