January 30, 2019

VANCOUVER, British Columbia, Jan. 30, 2019 (GLOBE NEWSWIRE) — Euro Manganese Inc. (TSX-V/ASX: EMN) (the “Company” or “EMN“), today announced the results of the Preliminary Economic Assessment (“PEA”) for the development of Western Europe’s largest manganese deposit owned by Mangan Chvaletice s.r.o. (“Mangan”), a 100% owned subsidiary of EMN in the Czech Republic, the Chvaletice Manganese Project (“Chvaletice Manganese Project”, “CMP”, or “Project”), and provided further information for the Company’s development plans for 2019. All economic values are in US dollars unless indicated otherwise.

HIGHLIGHTS:

PEA based on the recycling of a 27 million tonnes Measured and Indicated tailings resource (98.3% Measured) with a combined grade averaging 7.33% Mn, without the requirement of any hard rock mining, crushing or milling.
25-year project operating life producing 1.19 million tonnes of high-purity electrolytic manganese metal (“HPEMM”), two-thirds of which is expected to be converted into high-purity manganese sulphate monohydrate powder (“HPMSM”).
Saleable product includes 404,100 tonnes of HPEMM and 2.35 million tonnes of HPMSM, focusing principally on Europe’s rapidly emerging electric vehicle battery industry.
Flexibility to supply either HPEMM or HPMSM, to suit customer preference.
Pre-tax NPV of $782 million and after tax NPV of $593 million, using a 10% real discount rate.
$404 million in pre-production capital, $24.8 million in sustaining capital, and $31 million in working capital, with an ungeared, pre-tax 25.2% IRR with a 4.5-year payback, and a post-tax 22.6% IRR with a 4.9-year payback.
Project economics are based on projected average HPEMM (containing 99.9% Mn) price of $4,617/tonne and HPMSM (containing 32% Mn) price of $2,666/tonne over the project life.
Targeting production of ultra-high-purity electrolytic manganese metal with specifications exceeding 99.9% Mn and ultra-high-purity manganese sulphate monohydrate with a minimum manganese content of 32.34%, which exceed typical industry standards.
Exceptionally green project credentials. Project designed to meet or exceed all Czech and European safety, health and environmental standards, to remediate the Chvaletice tailings and arrest ongoing pollution related to unlined historical tailings piles.
Access to excellent transportation, energy and community infrastructure.
Proposed process plant site to be located in an industrially-zoned brownfields site, where a historical process plant generated the Chvaletice tailings.
Sophisticated, stable and business-friendly European Union jurisdiction that is highly supportive of new and, especially, green investments.
Robust project economic potential and rapidly growing market demand for high-purity manganese products support a wide range of potential financing alternatives.
Opportunities exist to enhance returns through process optimization initiatives and various investment incentives that may be available through the Czech Republic and European Union.
Next steps: Build and commission a Demonstration Plant in 2019 to produce multi-tonne, High-Purity Manganese product samples for customer testing and qualification, in conjunction with ongoing studies leading to completion of a feasibility study and submission of permit applications that will require further environmental investigations.

Marco Romero, President and CEO of EMN, commented:

“The PEA demonstrates the compelling potential of the Chvaletice Manganese Project. Euro Manganese is in a unique position in the battery industry, with its 100% holding of Western Europe’s most significant and strategically-located manganese deposit. What makes this project even more significant for an automotive industry focused on making our world greener, and for other consumers striving to secure sustainably produced raw materials, is that these products would be produced by recycling waste.”

Dr. Roman Shklanka, Chairman of EMN, added:

“The advent of electric vehicle manufacturing is transforming the entire global automobile industry. Revolutionary changes are taking place before our eyes and these have created unprecedented opportunities for an entirely new battery raw materials supply chain. Manganese is emerging as a key component in the dominant formulations of lithium-ion batteries, which are expected to drive strong demand for highly-refined manganese products well into the coming decades. A great deal of high-purity manganese materials production capacity needs to be brought on stream to meet the requirements of electric vehicle battery makers alone. Our plan is to be there for them, as a reliable supplier of environmentally-superior, high-purity manganese products. Our strategic location in the Czech Republic, central to a major emerging cluster of electric vehicle plants and a related ecosystem of chemical, cell and battery producers, our 25-year Project operating life, and our focus on the green production of high-purity manganese products made from the remediation of an old environmentally-impacted site, has attracted the attention of lithium-ion battery, battery precursor and cathode makers around the world.”

Mr. Romero continued, “Our Project team is now focused on further defining and refining our plans to advance the Project through front-end engineering and optimization work, and on the efficient progression of Project permitting. Planning, process engineering design and metallurgical test work are ongoing, ahead of the upcoming feasibility study, which we target completing by late 2019. Our plan for this year includes building and operating a demonstration plant capable of producing multi-tonne, high-purity manganese product samples for customer testing and qualification. Our 2019 plans also include intensifying community, stakeholder and regulatory consultation, and the filing of Project Permit Application.”

The PEA is based on a Measured and Indicated Mineral Resource Estimate, as detailed in the NI 43-101 and Technical Report prepared by Tetra Tech on January 28, 2019, a copy of which is filed on SEDAR and can be found on the Company’s website. The JORC Technical Report is expected to be lodged with the Australian Securities Exchange (“ASX”) within the next week. None of these Mineral Resources have been converted to Mineral Reserves. The PEA is considered preliminary in nature and includes estimated costs that are subject to an approximate margin of error of plus or minus 35%. Accordingly, there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not by definition have demonstrated economic viability.

This PEA was compiled and project-managed by Tetra Tech Canada Inc. (“Tetra Tech”), Vancouver, with major input from CINF Engineering Ltd (“CINF”) (comprehensive process design, plant engineering, equipment selection and testing), Changsha Research Institute for Mining and Metallurgy (“CRIMM”) (metallurgical testwork, process design, product development and pilot plant testing), Bilfinger Tebodin Czech Republic (“Tebodin”) (Czech and European cost estimation, localization and environmental services), GET s.r.o. (“GET”) (geology and sampling, environmental and tailings extraction planning) and Sudop Ltd (railway infrastructure design study). An updated NI 43-101 Technical Report on the Chvaletice Manganese Project including results of the PEA will be filed within 45 days on SEDAR and made available on the Company’s website.

Project Design Approach and Benefits to Local Residents

The CMP process plant is being designed to reliably and cost-effectively produce HPEMM and HPMSM products that meet or exceed all known customer specifications, including those for low-cobalt NMC cathode formulations, while complying with the stringent Czech Republic and European Union health, safety and environmental standards. In setting the life of the Project at 25 years with stable production levels, the goals of providing a long-term stable product supply for our customers, market stability and economic benefits for local communities and the citizens of the Czech Republic, were balanced against the generation of acceptable rates of return for the long-term investment that are required by EMN to develop the Project.
The Project is designed to produce high-purity manganese products, anticipating customer specifications for the emerging specifications for low-nickel battery formulations, produced with the cleanest technology available, assuring customers product quality, verifiable provenance and n small environmental footprint.
The Project would result in the environmental remediation of a polluted site, where metals and other compounds currently leach into the groundwater. As extraction, reprocessing and proper disposal of the Chvaletice tailings is carried out, the site will be progressively rehabilitated to be in compliance with Czech and European environmental requirements.
Modern, conventional and commercially-proven technologies that are employed in a variety of industries were incorporated in the various components of the CMP process flowsheet.
The Company has extensively engaged and plans to continue meaningful consultation with local residents, communities, organizations and regulatory agencies, soliciting active local participation and input in the Project’s evaluation and planning process.
Since the inception of the CMP, the Company has sought-out, trained and helped to develop numerous talented Czech professionals. EMN expects that the project would employ Czech residents during construction and operations. The Project would be expected to employ approximately 400 people during operations.
During its construction period and its 25-year life, total expenditures within the Czech Republic are estimated at $2.70 billion (CZK 62.0 billion), which would include corporate and payroll taxes and royalties payable within the Czech Republic of approximately $1.07 billion (CZK 23.8 billion).

Resource Estimate

Tetra Tech was engaged to oversee the planning and execution of sampling and assaying, to prepare the updated Resource Estimate for EMN’s Chvaletice Manganese Project, to prepare the Technical Report in accordance with National Instrument 43-101 – Standards and Disclosures for Mineral Projects, and to prepare the independent JORC Code technical report in accordance with the Joint Ore Reserves Committee Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 Edition (“JORC Code”). The 43-101 Technical Report, entitled “Technical Report and Mineral Resource Estimate for the Chvaletice Manganese Project, Chvaletice, Czech Republic”, with an effective date of December 8, 2018, was filed on SEDAR on January 28, 2019. The JORC Code Technical Report is expected to be lodged with the ASX within the next week.

The updated Mineral Resource Estimate resulted in a reclassification and upgrade of the tailings contained in the three Chvaletice tailings cells to Measured and Indicated categories, from Indicated and Inferred. The Project’s combined Measured and Indicated Resources now amount to 26,960,000 tonnes, grading 7.33% total manganese and 5.86% soluble manganese, as detailed in Table 7 below:


Table 7 – Chvaletice Mineral Resource Statement, Effective December 8, 2018

Notes:

Estimated in accordance with the Canadian Institution of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral Resources and Mineral Reserves adopted by CIM Council, as amended, which are materially identical to JORC Code.
The Chvaletice Mineral Resource has a reasonable prospect for eventual economic extraction. Mineral Resources do not have demonstrated economic viability, and no Mineral Reserves have been defined for the Project.
Indicated Resources have lower confidence that Measured Resources. A break-even grade of 3.20% total Mn has been estimated for the Chvaletice deposit based on preliminary pre-concentration operating costs of US$5.22/t feed, leaching and refining operating cost estimates of US$173/t concentrate, 63% recovery for magnetic separation derived from the average total Mn recovery of 87.7% on the average head grade, 71% recovery for leaching and refining, and a metal price of US$2.00/kg for 99.7% EMM (Shanghai Metals Market, Dec 2018). The price for high purity 99.9% EMM is expected to be higher.
A cut-off grade has not been applied to the block model. The estimated break-even cut-off grade falls below the grade of most of the blocks (excluding 10,000 tonnes which have grades less than 3.20% total Mn). It is assumed that material segregation will not be possible during extraction due to inherent difficulty of grade control and selective mining for this deposit type.
Grade capping has not been applied.
Numbers may not add exactly due to rounding.

PROCESSING FACILITIES DESCRIPTION:

Tailings Extraction, Residue Storage Facility and Reclamation

In the tailings extraction plan, the three tailings cells would be excavated in a counter-clockwise sequence, starting with Cell #3, followed by Cells #1 and #2. Tailings would be extracted using shovel excavators and hauled by truck to an intermediate re-pulping and a covered surge pile/storage station located between Cells #2 and #3. The storage station would create a 7-day material stockpile, whereby excavation and process waste dry stacking operations are limited to day time on weekdays only. Re-pulped tailings will be fed to the magnetic separation plant via a slurry pipeline on a continuous basis.

A blend of non-magnetic tailings (NMT), washed leach residue (LR) and gypsum materials from the process plant would be conveyed using a tube conveyor to the storage station and placed and compacted in the lined Residue Storage Facility (“RSF”). The excavated area exposed after extraction of the existing tailings would be lined with a geomembrane liner. The facility will be constructed in stages to suit residue storage requirements and to minimize the footprint of tailings and process residues exposed to the air at any given time. An initial starter cell would be constructed immediately adjacent to north of the existing Cell #2. Subsequent cells would be constructed within the extracted-out footprint of the tailings piles. Design features of the filtered residue storage facility include a geomembrane lined bottom, perimeter surface water diversion and a contact water collection system that is integrated with the overall site water management system. Dust management would include the implementation of modern dust suppression methods on open faces, interim stack surfaces and haul roads, as required. Progressive cover placement/reclamation would be undertaken as an integrated part of the residue stacking procedure. The residue stack cover would consist of a low permeability soil and/or geomembrane cover to inhibit erosion and infiltration, and a growth media layer to support vegetation growth. The cover would be placed progressively when residue crest and perimeter stack slopes meet design grades. The site would be expected to be fully reclaimed and brought back into productive community use that would be established in consultation with local residents, regulators and national government agencies. The RSF would be monitored during the post-closure period for geotechnical and environmental performance.

Notes:
1.        Tonnage and grade in Table 8 were calculated by GET and includes an overall 0.5% manganese loss factor and no dilution.
2.        Approximately two-thirds of the annual HPEMM production is converted to HPMSM on the site, with the balance being sold as HPEMM.
3.        The combined overall recovery of manganese from tailings to high purity manganese products is estimated to be 59.2% over the life of the Project, excluding the extraction manganese loss factor of 0.5%. Manganese recoveries in the production of HPEMM and HPMSM are expected to average 60.3% and 58.7%, respectively.

High Purity Manganese Products Production Facility

The processing facilities, including ancillary facilities, and process flowsheet for HPEMM and HPMSM production from the CMP tailings were designed by CINF together with EMN and Tetra Tech, based on the comprehensive metallurgical test results provided mainly by CRIMM. Tebodin provided engineering services to define local regulatory design requirements and review the design compliance.

The design work included preliminary process circuit and process equipment optimization. Mass, energy and water balances were simulated and estimated by a combination of METSIM modelling, calculations using results from the metallurgical test work program and CINF’s experience in designing EMM and MSM process plants. Key equipment items were sized and selected by the design team incorporating inputs from potential Chinese equipment vendors.

The CMP process plant has been designed to have a 25-year project life at a nominal production rate of 48,000 tonnes per annum of HPEMM by extracting approximately 1.1 million tonnes of tailings per year. Two-thirds of the annual HPEMM flake production would be expected to be converted to approximately 100,000 tonnes per annum of HPMSM. A progressive ramp up of HPEMM sales has been assumed to limit potential market supply imbalances in the first four years of production. This product mix is expected to best meet the high purity manganese market demand expected in current and future low-cobalt lithium-ion battery formulations. The HPEMM product containing >99.9% manganese is expected to be sold as flakes and powders and would be produced without the use of selenium and chromium. The CMP HPMSM product is designed to contain no less than 99.9% manganese sulfate monohydrate (MSM) and a minimum of 32.34% manganese and will be sold in powder form, produced without the use of fluorine. The proposed process flow sheet is illustrated in Figure 1:

A photo accompanying this announcement is available at http://www.globenewswire.com/NewsRoom/AttachmentNg/e1f4f44f-c53f-434f-ae22-6e2a6ee43446

The major unit operations in the CMP flow sheet are:

Excavated tailings would be re-pulped and pumped via a pipeline carried by an overhead bridge that would cross Highway #322 and the railway line and related spurs that adjoin the proposed process plant site located immediately south of the tailings piles.
The tailings slurry would be beneficiated in a wet, high-intensity magnetic separation circuit that upgrades the manganese grade of the leach feed to approximately 15% total manganese and rejects an average 57.7% of the feed to non-magnetic tailings, with an expected 86% manganese recovery. The magnetic concentrate and non-magnetic tailings produced would be dewatered using thickeners and filters. The concentrate would be fed to the downstream leach process and the dewatered tailings, together with the washed leach residue would be dry stacked at the RSF.
The magnetic concentrate cake would be re-pulped using anolyte solution from the electrowinning tank house and leached using dilute sulfuric acid at 90^oC for approximately 6 hours. Neutralization of the slurry would be achieved using hydrated lime. Air sparging of the neutralized slurry would be used to cost-effectively coprecipitate the substantial quantities of impurities that leach with the manganese. The leach pulp would be filtered in automatic pressure filters to separate pregnant leach solution from the leach residue.
The leach residue would then be washed with process water in a multi-stage counter current decantation circuit and dewatered using pressure filtration prior to co-disposal with the non-magnetic separation tailings in a lined dry stack tailings storage facility that is progressively constructed in excavated areas of the CMP tailings cells.
The wash water from the leach residue washing circuit would be treated for manganese and ammonia recovery to minimize manganese and ammonia losses. The wash water recovery system recovers manganese units to the leaching circuit in the form of manganese carbonate. The spent wash water solution would be treated to recover ammonia using a conventional lime boil process and would produce a gypsum by-product, the value of which is not included in the Project’s economics. The recovered ammonia would be reused in the HPEMM production circuits. The inclusion of the leach residue washing circuit with its associated wash water recovery circuit is expected to be a world-leading industry practice for the hydrometallurgical processing of manganese ores. Returning clean washed tailings to the carefully prepared containment cells in the excavated areas of the tailings progressively remediates the environmental impact risks of legacy mining operations.
The pregnant solution from the leaching circuit would be purified to remove heavy metals and other impurities and stabilized to prevent uncontrolled crystallization of salts to produce the solution for the downstream electrowinning process.
Electrowinning would be conducted in electrowinning cells following addition of sulphur dioxide to the tank house feed solution. The tank house would have the capacity to produce 50,000 t/a HPEMM using an energy efficient and selenium free process. The proposed electrowinning circuit is designed to have a plating cycle of 24 hours at a cell voltage of 4.2 to 4.4 V and an average cathode-current density of 320 to 370 A/m². Cathodes would be harvested using automatic harvesting machines, washed, passivated without the use of chromium and stripped of electrodeposited manganese metal using industry-standard automatic cathode plate stripping machines. The safety and health standards that have been used in the design of the CMP tank house include comprehensive mist emission control and mechanical handling systems that eliminate manual handling of cathodes and other processes. Tank house system design features include the recovery of anode slimes to minimize manganese losses, as well as diaphragm cleaning and ongoing cell maintenance operations. Approximately two-thirds of the HPEMM flakes would then be used as feed for HPMSM production. The remaining HPEMM flakes would be packed and directly shipped to customers. Future opportunities include the sale of powders in addition to flakes.
A magnesium removal process has been incorporated into the process plant design to ensure efficient electrowinning operations and high-quality product. The magnesium removal process would maintain the magnesium concentration in the electrowinning solutions at a level that prevents uncontrolled precipitation of salts and scaling. The process would use low cost reagents without incurring significant losses of manganese and reagent units.
The base case PEA production plan proposes to dissolve approximately two-thirds of the HPEMM flakes using sulfuric acid to produce 100,000 t/a of HPMSM powder in a dust-free chemical processing facility. The dissolved HPMSM solution would be further purified to remove trace impurities carried by the HPEMM flakes. This plant design assumes the feed solution will be concentrated using an energy efficient, low temperature mechanical vapor recompression (MVR) crystallization process to generate a single specification of manganese sulfate monohydrate crystals. The HPMSM crystals would be separated from the saturated MVR crystal slurry using centrifuges. The dewatered crystals would be dried using disc dryers to produce the final HPMSM powder, while the spent feed solution would return to the HPEMM dissolution circuit. The dried HPMSM powder product would be packed prior to being shipped in trucks or containers to customers worldwide.

Environmental Impacts, Permitting and Community Engagement

The vicinity of the Chvaletice tailings has been significantly impacted by past mining and related heavy industrial activities. Mining activity at Chvaletice ended in 1975. Czech law exempts land owners and developers from impacts prior to 1989, when communism ended in then Czechoslovakia.

Environmental baseline studies and other environmental studies have been in progress since the summer of 2016. These studies include collection of flora, fauna, hydrological, hydrogeological, climatic, air quality, land-use and socio-economic data, as well as airshed and emissions modelling.

Since 2017, GET, a Czech mining, geological and environmental services firm, has produced several studies for the Project, including environmental baseline studies. These included ecosystem mapping, documentation of the physical and environmental characteristics of the CMP site and an assessment of land use plans of the adjoining municipalities. Significant local features were recorded, including sensitive and protected areas, vegetation, landscape elements, and areas or sites of historical, cultural, archaeological or geological importance. Climate, air, water, soil, natural resources, fauna, flora and ecosystems, landscape and population of the area were inventoried. The baseline studies provide an overall assessment of the environment conditions that prevail in the Project area of interest.

Tebodin, the Czech division of a major European industrial and chemical engineering firm, has provided localization services for EMN that identified local requirements and permits required for the CMP. Tebodin also conducted wide-ranging process plant site selection studies, prior to Mangan securing the currently proposed plant site. They also provided local operating and construction costs estimates, such as reagent and logistic costs, operation consumables, duties and taxes, bulk construction material rates, labour surveys, engineering and construction services and energy supply and costs. Other work by Tebodin, included a review of local regulatory requirements for the permitting process and a review of Czech environmental regulations, standards and environmental practices, including waste water, waste and tailings storage, air, noise and other regulations. A time schedule for the process of an environmental impact assessment, environmental permits and building permits were provided, which suggested that permitting could take approximately 16 months from the time the permitting process is initiated.

EMN has initiated pro-active and regular consultation with community stakeholders, which are expected to intensify as the CMP evaluation and planning advances. In November 2017, the Company’s subsidiary, Mangan, inaugurated a Project Information Center in the Town of Chvaletice’s Municipal Culture House, to provide residents with opportunities to learn about the CMP, help them to develop relationships with the Company and its team, and to provide feedback and suggestions during the Project evaluation and planning stage. In November of 2018, Mangan relocated its registered office to Chvaletice. This move is intended as a first step towards ultimately basing its head office in this municipality, close to its operations.

Due to the location of the CMP on the shore of the Labe River and overlying a shallow aquifer in the Labe Valley, there are environmental sensitivities related to ongoing tailings runoff and impacts to local groundwater. Currently, EMN has knowledge of impacted groundwater caused by the historical mining and processing activity in the area, particularly the ongoing leaching of metals and other pollutants from the tailings. The Company continues to regularly monitor these impacts in groundwater wells. The Company expects that its proposed reprocessing of the Chvaletice tailings will result in a significant reduction or elimination of ongoing groundwater pollution caused by the existing unlined tailings facility.

Planning and preparation of the Project’s permit application has been initiated, with the objective of filing a Project Description/Notification early in 2019 with the Czech Ministry of the Environment. The Project Description/Notification will include a description of:

Manganese production process and resulting environmental footprint;
Results of baseline and other studies conducted to date;
Health, safety and environmental management plans;
Impact assessment, impact mitigation and avoidance plans/measures;
Socio-economic impacts on local communities; and
Reclamation plans/objectives.

The Project Description will be available to local communities, residents, organizations and regulators, during a public comment and consultation period. The Project Description and the input and comments received, as well as any requirements for changes or additional studies, will serve as the basis of further environmental studies that will support the approval of permits.

Planning is underway to design, build and commission a demonstration plant in the Czech Republic that will provide bulk, multi-tonne finished product samples for customer evaluation. This will provide confirmation to the customers of the ability of EMN to meet high product specifications. The demonstration plant will enable process optimization and testing for the product development. In addition, it is expected to serve as a testing and training facility for future operators.

Value Enhancing Opportunities

The Company expects to continue evaluating potential value-enhancing opportunities for the Project as it moves through the feasibility stage. These include the potential for on-site production of sulphuric acid, optimizing building sizing and layout, equipment selection, solid-liquid separation methods, alternative magnesium removal methods, manganese sulphate crystallization technologies, leaching methods, waste generation minimization, as well as minimizing energy and water consumption. EMN also plans to evaluate the possibility of selling by-product magnesium sulfate for agricultural use. These opportunities and others will be evaluated within the scope of work of design studies of the CMP feasibility study program.

Cautionary Statement

The projected extraction method, potential production profile and project plan are conceptual in nature and additional technical studies will need to be completed in order to fully assess their viability. There is no certainty that a potential tailings recycling operation will be realized or that a production decision will be made. A production decision that is made without a feasibility study will carry additional potential risks. Project design and extraction schedules, metallurgical flow sheets and process plant designs may require additional detailed work and economic analysis and internal studies to ensure satisfactory operational conditions and decisions regarding future targeted production.

The PEA is also based on the material assumptions outlined in this news release. These include assumptions about the availability of funding. While EMN considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the PEA can be achieved.

To achieve the range of outcomes indicated in the PEA, excluding working capital, funding in the order of US$430 million ‐US$440 million is assumed to be required. Investors should note that there is no certainty that EMN will be able to raise that amount of funding when needed. It is also likely that such funding may only be available on terms that may be dilutive to or otherwise affect the fundamental value of EMN’s existing shares. Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the PEA.
