Euro Manganese Announces Results of Life Cycle


VANCOUVER, British Columbia, Aug. 02, 2022 (GLOBE NEWSWIRE) — Euro Manganese Inc. (TSX-V and ASX: EMN; OTCQX: EUMNF; Frankfurt: E06) (“Euro Manganese“, the “Company” or “EMN“) is pleased to release highlights of the Life Cycle Assessment (“LCA” or “Study“) recently completed for the Company’s Chvaletice Manganese Project (“CMP” or “Project“) located in the Czech Republic.

Euro Manganese engaged Minviro Ltd. (“Minviro“), a UK-based and globally recognized sustainability and life cycle assessment consultancy, and RCS Global Ltd. (“RCS Global“), a leading global auditor of battery material supply chains, to conduct a cradle-to-gate, critically reviewed study quantifying the environmental impacts, including the carbon footprint, of producing high-purity manganese products from manganese-rich historic mine tailings at the CMP.

The results of the LCA validate the environmental value proposition of the CMP and identify potential opportunities for further impact reduction. Delivery of the LCA is timely as Euro Manganese continues to engage with customers in the Electric Vehicle (“EV“) battery/automotive space, each of whom are testing and qualifying both the chemistry and environmental credentials of EMN’s high-purity manganese products.

Highlights

  • Using 100% renewable electricity to power the processing plant significantly reduces the CMP’s carbon footprint, measured in the LCA as Global Warming Potential (“GWP“). The Company is actively working to secure renewable power offtake contracts with a potential target mix of 50% wind and 50% solar to meet the plant’s energy requirements. The Company’s working assumption is the use of 100% renewable electricity, referred to as the Target Scenario in the LCA.
  • Assuming the use of renewable electricity, the Project’s GWP is expected to be 6.6 kg CO2 eq. per kg of high-purity electrolytic manganese metal (“HPEMM“) and 2.3 kg CO2 eq. per kg high-purity manganese sulphate monohydrate (“HPMSM“). Assuming the standard Czech electrical grid mix, the total GWP impact is expected be 13.9 kg CO2 eq. per kg HPEMM and 4.8 kg CO2 eq. per kg HPMSM.
  • The results of the GWP impact analysis have been divided into three scopes, following the guidelines of the Greenhouse Gas (“GHG“) Protocol, which provides the Company with a full GHG emissions inventory.
  • The LCA confirms multiple environmental benefits from the remediation of the historic tailings area, particularly in terms of soil quality and freshwater quality. Both improve over the lifetime of the Project as remediation avoids the current leaching of metals and reduces the impacts of the historic tailings to soil and water streams.
  • Opportunities exist to further reduce the CMP’s carbon footprint by sourcing reagents from manufacturers with lower environmental impact than those assumed in the study. The Company is committed to identifying and selecting suppliers with commitments to decarbonization.
  • The LCA was conducted according to the requirements of ISO-14040:2006 and ISO-14044:2006, which included a critical review by an independent LCA expert, and will provide Euro Manganese with an independently verified assessment for financiers and customers. RCS Global also reviewed and commented on the LCA study.
  • Minviro is also undertaking a benchmarking exercise where the CMP’s GWP will be compared against similar projects and operations producing high-purity manganese products. The Company intends to release the results of this analysis once complete.

Dr. Matthew James, Euro Manganese’s President and CEO, said: “I am pleased the results of this Life Cycle Assessment confirm the environmental credentials of the Chvaletice Manganese Project, namely its low carbon footprint and the net positive benefits of remediating the historic tailings area, where the quality of soil and freshwater actually improve over the lifetime of our Project.  

These LCA results are a crucial part of customer qualification, as transparency into the origin and environmental footprint of battery metal production is increasingly important as automotive manufacturers use strategic procurement to meet their targets of lower carbon emissions across their supply chains.

Euro Manganese’s plans to purchase 100% renewable electricity reduces the GWP to 2.3 kg CO2 eq. per kg high-purity manganese sulphate. To put this in context, the Nickel Institute reports1 a GWP of 5.4 kg CO2 eq. per kg of nickel sulphate. I am confident the use of renewable energy will show our results are favourable against similar operations producing high-purity manganese products, to be confirmed in the benchmarking study currently underway.

Euro Manganese has the only known supply of manganese ore in the European Union, making our high-purity manganese products fully traceable from mine to market, and it is our duty to develop that resource in the most environmentally responsible manner.”

Scope of the Life Cycle Assessment

The LCA evaluates the life cycle impact of the two high-purity manganese products that the CMP produces, HPEMM and HPMSM. The reported values are based on the production of 1 kg of HPEMM and 1 kg of HPMSM respectively from manganese-rich historic sulfidic mine tailings. The process assessed is from the point of tailings extraction (cradle) to HPMSM production (end gate) and is based on data and the production process outlined in EMN’s Definitive Feasibility Study (“DFS”), the results of which were released on July 27, 2022.

The Study assesses two scenarios, a baseline, where electricity demands of the Project are met by the Czech grid, and a target scenario, where electricity demands are met by renewable energy sources. The transport of reagents, sourced from within Europe, is included in the scope.

The LCA measures five impact categories: the CMP’s global warming potential, water scarcity footprint, land use, freshwater eutrophication potential and freshwater ecotoxicity potential. Results of these categories can be found in the Results Summary Table in Appendix I.

Global Warming Potential

The CMP’s GWP is expected to be 6.6 kg CO2 eq. per kg HPEMM and 2.3 kg CO2 eq. per kg HPMSM assuming 100% renewable electricity is used. Assuming electricity from the standard Czech grid is used, the Project’s GWP is expected to be 13.9 kg CO2 eq. per kg HPEMM and 4.8 kg CO2 eq. per kg HPMSM. The GWP can be subdivided into Scope 1, 2 and 3 GHG emissions, detailed in the Table below.

Note: Totals may not add exactly due to rounding.

  • Scope 1: direct GHG emissions from owned or controlled sources; for example, emissions associated with the combustion of fossil fuels on-site, such as process emissions.
  • Scope 2: indirect GHG emissions from the generation of purchased energy; for example, thermal or electrical energy that is imported and used at site.
  • Scope 3: any other indirect upstream emissions; for example, from the impact of manufacturing consumables and transport of reagents.

The contributors to GWP in the production of HPEMM are mostly associated with electricity use in the electrowinning stage and quicklime consumption in the Fe/P removal stage. The contributors to GWP in the production of HPMSM are mostly associated with the production of HPEMM, as HPEMM is a precursor product to the further-refined HPMSM product.

Water Scarcity Footprint

The CMP’s water scarcity footprint is expected to be 29.2 kg water eq. per kg HPEMM and 11.0 kg water eq. per kg HPMSM assuming the target scenario and 35.2 kg water eq. per kg HPEMM and 13.7 kg water eq. per kg HPMSM assuming the baseline scenario. For both products, direct water use is the largest contributing factor to the Project’s water scarcity footprint, while indirect water use stemming from water embodied in energy and reagents does not contribute much. The potential for water deprivation to humans or ecosystems is not considered significant as the Project is located in an area with a low water scarcity index and the water used in processing is intended to be from secondary sources.

Land Use Transformation

In four of the five categories evaluated to assess the CMP’s impacts on land use, results showed a benefit to the environment of remediating the historic tailings area.

Categories showing a benefit included biotic production, groundwater regeneration, mechanical filtration and physicochemical filtration. An exception was in the soil erosion category as compaction and textures of the tailings area, processing plant and storage area will be changed after land occupation and transformation over the life of the Project. The likelihood of erosion is not considered significant. The total transformation impact is 4.2E-4 kg of increased soil loss per kg HPEMM, or 2.1E-4 kg of increased soil loss per kg HPMSM. 

Freshwater Eutrophication

The CMP’s freshwater eutrophication impact is expected to be 2.0E-3 kg P eq. HPEMM and -9.6E-4kg P eq. HPMSM assuming the target scenario and 9.7E-3 kg P eq. HPEMM and 3.5E-3 kg P eq. HPMSM assuming the baseline scenario. For both products, the main driver is the embodied impact of consuming material and energy inputs. Benefits to the environment were seen with the remediation of the historic tailings as further leaching of metals is avoided.

Eutrophication is the build-up of a concentration of chemical nutrients in an ecosystem which leads to abnormal productivity, such as excessive algae in rivers causing reductions in water quality and animal populations.

Freshwater Ecotoxicity

The CMP’s freshwater ecotoxicity impact is expected to be 15.1 Comparative Toxic Unit (“CTU“) eq. per kg HPEMM and 5.0 CTU eq. per kg HPMSM assuming the target scenario and 15.4 CTU eq. per kg HPEMM and 5.5 CTU eq. per kg HPMSM assuming the baseline scenario. The main driver for this is the use of chemicals in the purification process for HPEMM production, which has a large embodied upstream impact.

Ecotoxicity is the potential of a chemical substance to cause harm or damage to ecosystems, which, with respect to freshwater, is represented by the toxic effect on aquifer freshwater species in the water column.
