VANCOUVER, British Columbia, June 18, 2024 (GLOBE NEWSWIRE) -- Euro Manganese Inc. (TSX-V and ASX: EMN; OTCQB: EUMNF; Frankfurt: E06) (the "Company" or "EMN") is pleased to announce the successful completion of commissioning of its high-purity manganese Demonstration Plant at its Chvaletice Manganese Project ("Chvaletice" or the "Project") in the Czech Republic.

Highlights

  • Two independent external laboratories have confirmed that samples of high-purity manganese sulphate monohydrate ("HPMSM") made from high-purity electrolytic manganese metal ("HPEMM") produced at the Demonstration Plant (“DP”) meet the DP design target HPMSM specifications with low levels of impurities.

  • With all modules operating on a consistent basis, and producing on-spec products, this marks the completion of commissioning of the on-site Demonstration Plant.

  • Concurrently, the Permanent Operating Permit for the Demonstration Plant was received from the Department of Building and Spatial Planning of the Municipality of Chvaletice on June 12, 2024.

Final commissioning of the Demonstration Plant is now complete, with HPEMM produced from the electrowinning circuit of the Demonstration Plant used to produce target HPMSM specifications with low levels of impurities. The consistent operation of all modules is the other requirement of commissioning which has now been achieved.

The completion of commissioning of the Demonstration Plant allows the Company to produce bulk, multi-tonne finished product samples of HPMSM and/or HPEMM for prospective customers' supply chain qualification, thereby reducing the timeline to test products from the Chvaletice commercial plant in the future.

There are still optimisation activities underway, and the Demonstration Plant allows the Company to:

  • Collect relevant operational data to feed into the engineering of the commercial plant;

  • Prepare intermediate process stream and residue samples as required for vendor testing of process equipment for the commercial plant, thereby allowing process guarantees on selected vendor packages;

  • Produce by-product samples for testing and potential marketing of such by-products, e.g. magnesium carbonate;

  • Serve as a testing and training facility, providing learning opportunities and lessons that are being fed into the engineering process for the commercial plant; and

  • Test potential additional feedstock for the commercial plant, e.g., manganese by-product from recycled battery black mass processing.
