St-Georges Releases Initial Cathode Material EV Battery Test Results
St-Georges Releases Initial Cathode Material EV Battery Test Results
-FOR IMMEDIATE RELEASE-
Montréal, April 12, 2021– St-Georges Eco-Mining Corp. (CSE: SX) (OTC: SXOOF) (FSE:
85G1) is pleased to disclose the results of its initial electric vehicle (EV) cathode material battery
recycling tests aimed at specific car makers and OEM battery specifications.
100% of the targeted metals were recycled in situ or selectively leached in solution.
As previously disclosed in a press release titled “Initial Recovery Battery Test Results” dated
February 22, 2021, the Company has set aside a significant portion of its laboratories resources
to be able to perform “(…) additional tests to optimize the process of recovery of critical elements
(…) using synthet ic compounds to move the development along faster.” In a subsequent press
release titled “EV Batteries Recovery Tests Results: Lithium” dated March 18, 2021 , the
Company disclosed that it had “(…) completed EV battery characterization for the following car
makers: Tesla, General Motors (GM), Ford, Toyota, and Nissan. The batteries were sourced from
industry aggregators. The Company’s chemists and metallurgists created synthetic powder clones
of the metal’s components allowing the testing’s acceleration (…)” Additionally, leveraging the
support of some important stakeholders in the success of Company initiatives, St -Georges’
metallurgists were able to gather data on the composition of certain batteries in development or
about-to-be commercially deployed in th e coming year that are Lithium -Iron-Phosphate or LFP
(LiFePO4) based. These not -yet-on-the-market batteries have been conceptually characterized,
synthetically reproduced, and tested with the Company’s processing technology.
Four sets of battery category, covering all current car makers previously mentioned, along with
the addition of the LFP batteries, have been processed in St -Georges’ contracted pilot -plant
installations:
Main Core Powder Chemical Formula
LCO LiCoO2
LMO LiMn2O4
NMC LiNi0.33Mn0.33Co0.33O2
LFP LiFePO4
Cathode materials results
This initial test campaign's objective was to determine which metals were put in solution from
cathode materials using St-Georges’ proprietary acid -blend. From those experiments, it can be
deduced that Lithium, Iron, Phosphate, Cobalt, Nickel, and Magnesium can be expected to be
found in solution when using commercial batteries, on top of other metals such as Alumin ium,
Manganese, and Copper that can be recuperated in situ.
It is important to note that the LFP batteries might require a slightly different process to recycle
100% of the metals. Iron content generates a small amount of magnetism during the process while
everything else remains in line with other battery compounds.
Other powders made from cathode material (NCA [Nickel, Cobalt, Aluminum, Lithium] and LTO
[Titanium and Lithium]) are being shipped from St-Georges’ industrial chemical provider and will
be tested soon.
Anode materials.
The Company’s work on anode materials is moving along at a fast pace. The team expects to be
able to disclose certifiable results within 4 to 6 weeks. The primary materials being recycled from
the anode are graphite and silicon metal and, in smaller quantities, titanium. The team believe s
that these materials are currently more economical to mine than to recycle but believes that St -
Georges’ process will improve the total battery recovery value proposition by eliminating these
materials’ disposition costs. Management believes that any com parison to other competing
technology must consider costs, cathode, anode, casing, and everything in between. The same can
be said about the total material recuperation rate since cathodes are currently the global problem’s
low-hanging fruit.
