EUROPEAN METALS HOLDINGS LIMITED
Lithium Process Update
European Metals Holdings Limited ("European Metals" or "the Company") (ASX and AIM: EMH) is pleased to provide an update regarding the preferred metallurgical process route for the extraction of lithium from its 100% owned Cinovec Project in the Czech Republic.
As announced on 15 January 2016, the Company has been conducting independent studies to evaluate a number of existing lithium extraction methods. As a result of the positive results of those studies the Company has engaged with Dorfner Anzaplan to conduct the next level of advanced test work at its facilities in Hirschau, Germany.
Dorfner Anzaplan are a specialist in testing and engineering services for high value industrial and strategic minerals and downstream products and have had previous experience in the treatment of lithium minerals.
The Company has terminated its Heads of Agreement with Lithium Australia NL (ASX Code: LIT) involving the potential use of the Li-Max technology. Whilst the Company considers Li-Max to be a viable process warranting further investigation, it has been unable to arrive at terms that are commercially acceptable to the Company.
CEO Keith Coughlan commented:
"We are very pleased to be working with Dorfner Anzaplan to advance the Cinovec Project. Dorfner are a very well regarded specialist firm who have extensive experience working with lithium minerals and in dealing with European end users. Dorfner have had previous experience with the treatment of zinnwaldite (the Cinovec host rock) to extract lithium.
"We note with considerable interest the recent significant developments in the broader market for lithium and lithium products within close proximity to the Cinovec Project."

PROJECT OVERVIEW
Cinovec Lithium/Tin Project
European Metals owns 100% of the Exploration Rights to 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. Cinovec hosts a globally significant hard rock lithium deposit with a total Inferred Mineral Resource of 514.8Mt @ 0.43% Li2O. Within this resource lies one of the largest undeveloped tin deposits in the world, with total Indicated and Inferred Mineral Resources of 79.7Mt grading 0.23% Sn for
183,000 tonnes of contained tin. The Mineral Resource estimates are based primarily on over 83,000 metres of historic drilling and 21.5 km of historic underground development completed by the Czechoslovakian Government from the 1960s through to the 1980s. The deposit has previously had over 400,000 tonnes of ore mined as a trial sub-level open stope underground mining operation.
A Scoping Study conducted by specialist independent consultants indicates the deposit could be amenable to bulk underground mining. Metallurgical testwork has produced both battery grade lithium carbonate and high grade tin concentrate at excellent recoveries with the Scoping Study revealing a potential production cost of approximately $1,500 per tonne of lithium carbonate excluding tin and tungsten credits. 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.

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 per cent. lithium oxide (Li2O) content or per cent. lithium carbonate (Li2CO3) content.
Lithium carbonate equivalent ("LCE") is the industry standard terminology for, and is equivalent to, Li2CO3. 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 further below to get an equivalent Li2CO3 value in per cent. Use of LCE assumes 100% recovery and no process losses in the extraction of Li2CO3 from the deposit.
Lithium resources and reserves are usually presented in tonnes of LCE or Li.
To convert the Li Inferred Mineral Resource of 514.8Mt @ 0.20% Li grade (as per the Competent Persons Report dated 2 November 2015) to Li2O, the reported Li grade of 0.20% is multiplied by the standard conversion factor of 2.153 which results in an equivalent Li2O grade of 0.43%.
The standard conversion factors are set out in the table below:
Table: Conversion Factors for Lithium Compounds and Minerals
Convert from |
| Convert to Li | Convert to Li2O | Convert to Li2CO3 |
Lithium | Li | 1.000 | 2.153 | 5.323 |
Lithium Oxide | Li2O | 0.464 | 1.000 | 2.473 |
Lithium Carbonate | Li2CO3 | 0.188 | 0.404 | 1.000 |

"cut-off grade" | lowest grade of mineralised material considered economic, used in the calculation of ore resources | |
"deposit" | coherent geological body such as a mineralised body | |
"exploration" | method by which ore deposits are evaluated | |
"g/t" | gramme per metric tonne | |
"grade" | relative quantity or the percentage of ore mineral or metal content in an ore body | |
"Indicated" or "Indicated Mineral Resource" | as defined in the JORC and SAMREC Codes, is that part of a Mineral Resource which has been sampled by drill holes, underground openings or other sampling procedures at locations that are too widely spaced to ensure continuity but close enough to give a reasonable indication of continuity and where geoscientific data are known with a reasonable degree of reliability. An Indicated Mineral Resource will be based on more data and therefore will be more reliable than an Inferred Mineral Resource estimate |
|
"Inferred" or "Inferred Mineral Resource" | as defined in the JORC and SAMREC Codes, is that part of a Mineral Resource for which the tonnage and grade and mineral content can be estimated with a low level of confidence. It is inferred from the geological evidence and has assumed but not verified geological and/or grade continuity. It is based on information gathered through the appropriate techniques from locations such as outcrops, trenches, pits, working and drill holes which may be limited or of uncertain quality and reliability |
|
"JORC Code" | Joint Ore Reserve Committee Code; the Committee is convened under the auspices of the Australasian Institute of Mining and Metallurgy | |
"Kt" | thousand tonnes | |

"lithium" | a soft, silvery-white metallic element of the alkali group, the lightest of all metals | |
"lithium carbonate" | the lithium salt of carbonate with the formula Li2CO3 | |
"metallurgical" | describing the science concerned with the production, purification and properties of metals and their applications | |
"Mineral Resource" | a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such a form that there are reasonable prospects for the eventual economic extraction; the location, quantity, grade geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge; mineral resources are sub-divided into Inferred, Indicated and Measured categories | |
"mineralisation" | process of formation and concentration of elements and their chemical compounds within a mass or body of rock | |
