* Maiden Ore Reserve of 34.5 Mt @ 0.65% Li(2) O declared for Cinovec Project * Richard Pavlik, current in-country manager, appointed as Director * Short term funding secured
European Metals Managing Director Keith Coughlan said, "I am pleased to report a maiden Ore Reserve for Cinovec. The conversion of 34.5 million tonnes of Mineral Resource to Ore Reserve was facilitated by the recently published PFS. This is another significant step in the development of the largest lithium resource in Europe. I am also very pleased to welcome Richard Pavlik to the Board of Directors of European Metals on the resignation of Mr Pavel Reichl. Richard has made a significant contribution to the Company since taking the role of Country Manager in January and is a key component of the development of the project. On behalf of the Board I would like to thank Pavel for his role in the development of Cinovec to date. Pavel has been instrumental in securing the project and in managing a great deal of the early work. In addition, we have secured short term funding to allow us to continue work on the Definitive Feasibility Study whilst finalising discussions with a number of potential European based partners. It is the company's preferred route to partner with a European strategic investor for the bulk of the feasibility funding."

Mr Reichl will continue to provide geologic services on an as-needed basis.
INTERIM FUNDING
The Company is actively engaged in discussions with potential European strategic partners with regards to the funding and development of the Cinovec Project. Given the high level of interest in Europe in the lithium market, the Company is confident of a successful outcome in the near term in this regard. In order to allow sufficient time to finalise discussions and properly assess the various options open to the Company, the Company has arranged an interim funding facility to maintain momentum in developing the project.
This facility has been provided by an Australian based sophisticated investor, 6466 Investments Pty Ltd, and allows for the draw down of up to AUD 2 million in tranches as required over 12 months. Any funds drawn down will convert to CDI's in the Company at a 10% discount to the 10 day vwap in the Company's securities. The funds will be used in the preparation of the Company's Definitive Feasibility Study, for further drilling and general working capital. The issue of shares pursuant to draw downs does not require shareholder approval.
BACKGROUND INFORMATION ON CINOVEC
PROJECT OVERVIEW
Cinovec Lithium/Tin Project
European Metals owns 100% of the Cinovec lithium-tin deposit in the Czech Republic. Cinovec is an historic mine incorporating a significant undeveloped lithium-tin resource with by-product potential including tungsten, rubidium, scandium, niobium and tantalum and potash. Cinovec hosts a globally significant hard rock lithium deposit with a total Indicated Mineral Resource of 348Mt @ 0.45% Li(2) O and 0.04% Sn and an Inferred Mineral Resource of 309Mt @ 0.39% Li(2) O and 0.04% Sn containing a combined 7.0 million tonnes Lithium Carbonate Equivalent and 263kt of tin.
This makes Cinovec the largest lithium deposit in Europe, the fourth largest non-brine deposit in the world and a globally significant tin resource.
The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.
The recently completed Preliminary Feasibility Study, conducted by specialist independent consultants, returned a post tax NPV of USD540m and an IRR of 21%. It confirmed the deposit is be amenable to bulk underground mining. Metallurgical test work has produced both battery grade lithium carbonate and high-grade tin concentrate at excellent recoveries. Cinovec is centrally located for European end-users and is well serviced by infrastructure, with a sealed road adjacent to the deposit, rail lines located 5 km north and 8 km south of the deposit and an active 22 kV transmission line running to the historic mine. As the deposit lies in an active mining region, it has strong community support.
The economic viability of Cinovec has been enhanced by the recent strong increase in demand for lithium globally, and within Europe specifically.

LITHIUM CLASSIFICATION AND CONVERSION FACTORS
Lithium grades are normally presented in percentages or parts per million (ppm). Grades of deposits are also expressed as lithium compounds in percentages, for example as a percent lithium oxide (Li(2) O) content or percent lithium carbonate (Li(2) CO(3) ) content.
Lithium carbonate equivalent ("LCE") is the industry standard terminology for, and is equivalent to, Li(2) CO(3) . Use of LCE is to provide data comparable with industry reports and is the total equivalent amount of lithium carbonate, assuming the lithium content in the deposit is converted to lithium carbonate, using the conversion rates in the table included below to get an equivalent Li(2) CO(3) value in percent. Use of LCE assumes 100% recovery and no process losses in the extraction of Li(2) CO(3) from the deposit.
Lithium resources and reserves are usually presented in tonnes of LCE or Li.
The standard conversion factors are set out in the table below:

(Li), Tin (Sn) and Tungsten (W). Each metal has different in-situ grades, plant recoveries, operating costs and metal prices. To determine the revenue generated from a block of material in the block model there factors need to be taken into account. To do this the total revenue and
operating costs were calculated using a script in the block model. The cost was deducted from the revenue to produce a "Margin" value for each block. Where Margin is greater than zero, the block is flagged as ore. The metal prices, recoveries and formulae used to calculate the operating costs for purposes of the margin calculation are tabled below. (Please refer to the announcement on the European Metals Website for the Table described above - www.europeanmet.com.) =============== ============================================================ ================================================================== Using the factors tabled above the "Margin" value was calculated for each block in the block model. The breakeven grade is where Margin =0. All blocks with Margin greater than zero could be considered ore. Applying this criteria to the block model allowed a grade versus tonnage curve to be generated based on using the "Margin" field as the grade field. The resultant curve is shown in the Figure below. (Please refer to the announcement on the European Metals Website for the Table described above - www.europeanmet.com.) In order to optimise the value of the project a strategic decision was made by the client to mine at a higher grade than the average and to optimise the mined grade by reducing the tonnes and increasing the grade to the point where mine life becomes the constraint, or the mining becomes prohibitively selective. The production rate of the processing plant was set by EMH at 360,000 tpa of mica concentrate. This equates to approximately 1.7 million tpa of RoM ore. For a mine life of over 20 years, which was the requirement stated by EM, the mining inventory needs to be at least 34 million tonnes. Using the grade versus tonnage curve a cut-off of US$35/tonne Margin was selected. This resulted in the appropriate mine life while still allowing the use of bulk mining methods such as LHOS.

Block model The block model file used for this study was provided to Bara by EM in February 2017 and is entitled Cinovec_Resource_Model_17_02_2017.dm. The model is in Datamine format. The table below shows the fields in the block model that were used in the mine planning process. (Please refer to the announcement on the European Metals Website for the Table described above - www.europeanmet.com.) Mining method An evaluation was completed to establish the achievable extraction ratios with and without backfill, based on the geotechnical design criteria including pillar sizes and stope spans (see above). The preferred option was to mine with pillars support only, negating the requirement for a backfill plant. The selected mining method is long hole open stoping with pillar support. The payable ore will be split into blocks approximately 90 m long in the strike direction and 25 m high. The bottom of each block will be accessed in the central position by an access crosscut and the block will be mined out from the centre to the strike limit by drifting. The stope will be mined on retreat from the block extent, retreating to the access cross cut position. The stopes will be a maximum of 13 m wide with rib pillars between stopes of 4 to 7 m wide depending on stope height. Access to the stopes will be by footwall drives developed in the footwall at 25 m vertical intervals. All stope access crosscuts will be developed out of the footwall drives. The mine will be accessed by a twin decline system. A conveyor will be installed from the underground primary crusher on 590m Elevation to surface in the conveyor decline. The second decline will be used as a service decline for men, material and as an intake airway. Mining modifying factors Stope shapes were determined by use of stope optimisation software after application of minimum stope size and stope geometry. The design criteria specified included: * Cut-off - Margin >US$35 per tonne. This means that the average margin of the resultant stope shape must be greater than US$35/tonne.
* Stope width - 17 m (includes rib pillar, which was deducted as a tonnage loss later in the schedule) * Maximum stope height - Unlimited. Stope shapes greater than 25m high were later split by level and sill pillar losses accounted for. * Minimum stope height - 5m (height of ore drive). * Stope length - Minimum 10 m, maximum unlimited. Stopes were later split into stope blocks with maximum length of 180 m (two stopes of 90 m each) * Minimum footwall slope angle - 50(o) . After definition of the stope shapes mining modifying factors as described below were applied: Mining Exclusions 1. The Northern most portion of the orebody is located below the village. In this area it was agreed to leave an unmined crown pillar of at least 150 m between surface and the uppermost mining level. In other parts of the orebody the crown pillar was 70 m. 2. DSO created stope shapes according to the criteria specified above, but with no consideration of the development required to access these blocks. The design was edited to remove any blocks that were not practical to access, being either excessively far from planned development and too small to justify the access development, or small volumes on an elevation that is difficult to access being between mining levels. Pillar loss Total pillar loss is estimated to be 35%. Unplanned dilution In order to account for these mining inefficiencies unplanned dilution was added to all stope tonnage. Due to the large size of the stopes the dilution percentage is low at 3%. This allows for approximately 0.25 m of over break around the entire stope. Since the stopes are defined by a grade cut-off and the mineralisation is disseminated, there is not expected to be a sharp drop-off of grade outside the stope envelope. The dilution will therefore contain metal grade. The average grade of the resource below the margin cut-off of US$35/t has been applied to the dilution material in the mine plan. The grade of the dilution is: Li% - 0.22 Sn% - 0.04 W% - 0.01 Ore loss Ore loss does occur in mining operations due to mining inefficiencies. This can be due to factors such as: * Ore not loaded out of stopes * Grade control errors
* Haulage errors * Underbreak in the blasting operation * Stope hang ups To account for these inefficiencies an ore loss factor of 3% has been included in the mining schedule. This is a tonnage loss at the average grade of the block. Inferred Resources No inferred resources were included as ore in the pre-feasibility mine plan. Inferred resources were treated as waste. Infrastructure Surface Infrastructure The surface infrastructure has been designed to support the mining plan with consideration of the labour and mechanised equipment requirements of the operation in addition to the movement of rock, men and materials. The infrastructure is divided into two distinct areas, with the area at the portal servicing the initial development requirements and the second servicing the production phase. Allowance has been made for; * Security fencing. * Site access control and parking. * Development offices * Development change house and laundry. * Lamp house and crush. * Medical station. * Trackless workshop and wash bay. * Compressor station * Diesel farm. * Oil and grease storage, * Main store and material yard. * Capital laydown area * Service water storage and settling. * Downcast air heating. * Brake testing ramp * Main offices * Main change houses * Main laundry. * Training centre. * Parking and bus drop off zone * Fire systems * Potable water infrastructure including municipal Interface. * Sewage Infrastructure including municipal Interface. * Gas supply Infrastructure including municipal Interface. * MV electrical infrastructure including municipal Interface. * Explosives accessories magazine. Underground Infrastructure Underground infrastructure designs take into consideration the life of mine plan and aims to support the underground mining production and development activities. Underground infrastructure comprises: * Mine service water systems * Mine dewatering systems, including clear and dirty water pump stations. * Mine electrical reticulation * Control systems and instrumentation * Trackless workshops * Refuelling bays * Underground crushers, tips, and conveyors. The mine service water system is a based on a re-circulation design, with settled water from
the mining activities used as service water. This reduces the mine pumping requirement in turn reducing power costs. In terms of electrical reticulation, the Cinovec mining operation will require a bulk power supply of 3.5 MVA. Power will be provided by a local supply authority and it is anticipated it will be at 6kV. Underground Ore Handling The underground ore handling system is designed for 500 t/h and will comprise the following: * A primary tip, equipped with a static grizzly and a hydraulic rock breaker to break oversize lumps; * An ore-pass; * A primary crushing station, equipped with a vibrating grizzly feeder and jaw crusher; * A sacrificial conveyor (CV001), 18 m long, to protect the main decline conveyor; * A decline conveyor (CV002), 1,146 m long. =============== ============================================================ ================================================================== Metallurgical The beneficiation plant factors * The metallurgical process proposed and the process route consists or assumptions appropriateness of that process to the style of of crushing, SAG milling, mineralisation. classification, thickening and wet high intensity magnetic separation * Whether the metallurgical process is well-tested (WHIMS).

The process route selected utilizes standard, industry proven technology. The process route selected was based on the testwork carried out, and on the respective engineering companies' experience on other, similar projects. The samples used for the beneficiation plant testwork were quarter core composites from the drilling campaigns. For the comminution tests, composites were made up of the various ore types to provide an indication of variability. As composites of drill cores were used for the testwork, the samples are considered to be representative of the deposit. The variability in the deposit may be an issue in the plant operation, but additional testwork will be carried out during the feasibility study to inform on this issue. The mass of sample received for the testwork was 150kg, which enabled appropriate sized samples (taking into consideration that the study being
carried out is pre-feasibility) to be used for the various tests. The product recoveries were determined from the testwork, factors were not applied. Testwork has produced a saleable lithium carbonate product (>99.5% lithium carbonate) although the levels of fluoride (500 ppm) and silicon (300 ppm) were high. These elements are not generally considered to be deleterious elements in product specifications. Further testwork will be carried out to reduce these levels. No bulk samples were available for the testwork but were not required as the level of study was pre-feasibility. Pilot scale testwork will carried out during the feasibility study. The composite samples used for the testwork are considered to be representative of the ore-body and suitable for the testwork performed. The specification for the lithium carbonate product is a minimum of 99.5% lithium carbonate. This was achieved in the testwork. Testwork will be carried out during the next phase of the project to further improve on the quality of the product to be produced. =============== ============================================================ ================================================================== Environmental The Company has commenced * The status of studies of potential environmental the Environmental Impact impacts of the mining and processing operation.

This identified the environmental areas to be assessed and determined preliminary outcomes. The underground mine and surface portal is located on the border adjacent to an environmentally sensitive area - Natural park Eastern Krusne hory. The Project area is mostly covered by forests and treeless plateau with bushy growth. The area of Dubí township is covered by farm land (15%) and non-agricultural land (85%), out of that 80% are forests. Intensive biological investigation executed in 2016 identified 20 natural biotops, out of them 4 peat bogs, springheads, waterlogged spruce growths and mountain meadows) are protected within the Natura 2000. Screening process also identified 67 animal species - 2 amphibians, 2 snakes, 51 birds and 11 mammals living in the area. Of them, 14 species are protected. Through the area also runs the regional natural bio corridor K2. The Cinovec Sn/W Lithium Project is governed
by Act No.100/2001 Coll., on Environment Impact Assessment (hereinafter referred to as the "EIA Act"). The competent authority is the Ministry of the Environment (Environment Impact Assessment Department). An integrated permit is issued upon completion of the EIA process. In consideration of the exploitation mining licence to be granted and the expected production of the Li-W-Sn ore exceeding 1 Mt a year during the implementation of the Project, the EIA documentation must be prepared and assessed (full-scope EIA Report). The Cinovec Sn/W Lithium Project development documentation shall be structured as follows: * details concerning the Notifier, * details concerning the development project, * details concerning the status of the environment in the region concerned, * comprehensive characteristics and assessment of the Project impacts on public health and the environment, * a comparison of project versions (if any), * a conclusion, and * a commonly understood summary and annexes (opinion of the Building Authority, opinion of the Nature Protection Authority, expert studies and assessments). The following expert studies and assessments must be compiled during the EIA Documentation preparation stage: * noise impact study, * air quality impact study, * biological survey, * human health impact study, * transport impact study, * landscape impact study, and * water quality and hydrology impact study. In this case, with respect to the location of the Project at the border with Germany, the so-called "international assessment" provision applies (Section 13, Act No. 100). This process is more time-demanding - in an international assessment, the Ministry of the Environment may extend the deadlines to present views by up to 30 days; other deadlines (Sec. 12, Act.100) are extended adequately in such a case. EMH commenced the EIA process with the baseline study, prepared by GET, which identified the environmental areas to be assessed and determined preliminary outcomes. The project, mainly the underground mine and surface portal is located in environmentally sensitive area. From that perspective, the EIA will focus particularly on project impacts on European protected areas Natura 2000 (protected birds) and mine water discharge into surface streams due to the content
of Berylium and radioactive components. Considering the long-term mining history in region the Project will not significantly change the situation towards to environment and from that perspective all identified potential problems should be resolvable and EMH do not envision any fatal flaws will be encountered. The Cinovec EIA will focus particularly on Project impacts on European protected areas Natura 2000 (protected birds) and mine water discharge into surface streams. The Company has re-positioned key infrastructure to minimise impacts to both the environment and the community and has placed crushing facilities and fans underground to minimise noise as well as enclosing the mill to further reduce noise and visual impacts. Considering the long-term mining history in region and at the deposit itself, the Project will not significantly impact the environment. Waste Rock Acid-Base accounting (ABA): Acid-Base accounting (ABA) is a screening procedure whereby the acid-neutralising potential (assets) and acid-generating potential (liabilities) of rock samples are determined, and the difference, net neutralising potential (equity), is calculated. Samples were devoid of sulphides and have no potential to generate acid-mine drainage as confirmed through both the ABA and NAG test. However, the Neutralisation Potential of the samples were also very low and samples also had a very low total C content. However, the potential to leach at least As and F which should be further investigated through the column leach testing as these two parameters will also be present in neutral drainage from samples. The addition of acid to samples (ABCC method: 3 g sample in 100 ml water as per AMIRA, 2002) resulted in quick acidification confirming that the samples had almost no Neutralisation Potential. The pH curve is only slightly higher than for the Blank (distilled water). Net Acid Generation (NAG): The single addition NAG test was used to classify the acid generating potential of all 42 samples. The NAG test involves the reaction of a sample with hydrogen peroxide to rapidly
oxidise any sulphide minerals contained within a sample. The end result represents a direct measurement of the net amount of acid generated by the sample. This value is commonly referred to as the NAG capacity and is expressed in th is kg H2SO4/tonne. All of the samples tested were classified as non-acid forming. The ICP analysis of the NAG elution did not yield any significant results. This test is more appropriate where the sample have sulphides that can be oxidised with peroxide and ICP analyses indicate metals released. Tailings Tailings produced by the gravity circuit of the FECAB's beneficiation plant and the Residue Filtration Stream produce by the LCP require permanent impoundment in a suitable Tailings Storage Facility (TSF). For the PFS a conservative approach was taken by designing a dry stack tailings facility. Any water from the dry stacked tails is captured and recycled to the LCP process water feed. This approach, although higher in Capex, offers the most environmentally sustainable method of tailings impoundment. Tailings produced by the gravity circuit are filtered in two pressure filters to produce a filter cake with a moisture content of 18%. This moisture content is based of filtration test work performed on a representative tailings sample by Diemme(R) with the results interpreted by Ausenco and incorporated into the FECAB design. The FECAB filter cakes falls into a bunker below the pressure filters, from where it is collected by a wheel loader and loaded into an articulated truck for transfer to the dry stacks tails tip point. The articulate truck dumps the tailings filter cake where it is spread and compacted by a bulldozer. The estimated cost of the FECAB tailings disposal is $1.00/ wet tonne. The LCP tailings consist of leach residue filter cake produced by a pressure filter. As with the FECAB, the pressure filter drops the filter cake into a bunker for loading via a wheel loader. The estimated cost for LCP residue disposal is $1.50/ wet tonne. The loading, trucking and spreading of the tailings will be performed by a local contract
earth moving company. Data used as input criteria to the TSF design concept are listed in the table, which is considered adequate for PFS and has been derived from PFS level engineering. (Please refer to the announcement on the European Metals Website for the Table described above - www.europeanmet.com.) All permits for the tailings dam, waste rock dump and operations will be applied for when appropriate and as governed by Czech law. To date, permits for mine de-watering and preliminary mining permits have been received. =============== ============================================================ ================================================================== Infrastructure Currently, no infrastructure * The existence of appropriate infrastructure: exists at the mine site availability of land for plant development, power, and therefore allowance water, transportation (particularly for bulk has been made for all commodities), labour, accommodation; or the ease with support facilities required which the infrastructure can be provided, or by the planned mining accessed. operation. Surface infrastructure has been designed to support the mining plan with consideration of the labour and mechanised equipment requirements of the operation in addition to the movement of rock, men and materials. The infrastructure is divided into two distinct areas, with the area at the portal servicing the initial development requirements and the second servicing the production phase. The surface infrastructure design includes all facilities and services (such as offices, changehouses, workshops) as well as utilities and reticulation (such as power, water and gas utilities) to support the underground mining activities for the life of mine. Underground infrastructure designs take into consideration the life of mine plan and aims to support the underground mining production and development activities.

The ramp up of new EV model sales from major auto companies is generally considered to be the key driver of lithium demand in the short to medium term. Other factors include the increased production from battery manufacturing facilities and the continued inventory build within the supply chain. The Cinovec Project is located centrally and within close proximity to a number of major European car manufacturers. Benchmark expects the average forecasted price range for lithium carbonate 99.95% to be $ 9,500 to $ 13,000/tonne (USD) between 2017 and 2020. European Metals has considered this forecast in light of other independent forecasts such as Deutsche Bank, and on generally available lithium market commentary. For the purposes of the PFS with regards to financial modelling, a long-term average price of $ 10,000/t lithium carbonate FOB has been used. The graph below shows the Deutsche Bank lithium price forecasts to 2025.
