St-Georges Eco-Mining $SX $SXOOF Reports on Initial Battery Recovery Test Results $NNX.ca $OM.ca $ICM.ca $ATAO

  • Initial tests on lithium-ion batteries successful in the recovery of lithium, nickel and cobalt found as a coating on aluminium foil in the core of the batteries.
  • Leached more than 99% of the cobalt and of the nickel contained in the batteries.

St-Georges Eco-Mining Corp. (CSE:SX) (OTC:SXOOF) (FSE: 85G1) (CNSX:SX.CN) is pleased to disclose that its initial tests conducted on an array of lithium-ion batteries have been successful in confirming that the selective leach, conducted with its proprietary blend of acids, allows for the recovery of the lithium, nickel and cobalt that are found as a coating on aluminium foil in the core of the batteries.

The Company’s metallurgical team was able to leach more than 99% of the cobalt and of the nickel contained in the batteries. Furthermore, the aluminium foil used to hold the different metals in the batteries’ core remains intact and can be recycled.  

Company scientists are comfortable that the results obtained on these metals are repeatable and should scale. Initial lithium test results have been in line with expectations and require additional tests at scale prior to disclosure. These additional tests are ongoing, and results are expected sometime in March.

For testing, batteries were dismantled at the Company’s contracted pilot plant facility, CIMMS, under the supervision of qualified chemists and metallurgists. Enrico Di Cesare, St-Georges VP Research & Development, established the protocol and supervised the process. The batteries were dismantled manually, and the cores were immersed in St-Georges’ proprietary leach solution for 30 minutes. The Company expects to optimize and reduce this exposure duration with the aim of bringing it closer to the 5 min leach time required by the Nevada clays. Aluminium was taken out of the solution in its solid form and set aside. No test for residues was conducted on the aluminium in the preliminary tests. Metals were then targeted for recuperation in solution. The powders obtained were tested on-site and sent for independent testing by CIMMS
