European Metals Holdings Limited: Shallow Lithium Mineralization Intersected at Cinovec

European Metals Holdings Limited: Shallow Lithium Mineralization Intersected at Cinovec

 

European Metals Holdings Limited (“European Metals” or “the Company”) (ASX and AIM: EMH) is pleased to announce analytical results for two confirmation drillholes CIW-19 and CIW-20 at the Cinovec Lithium-Tin-Tungsten Project ("the project" or "Cinovec").

Key Points:

- The two drillholes are the most northern drilled by the Company and are collared near the old main shaft.

 

- Significant lithium mineralization intersected from less than 30m depth in both holes, these are the shallowest intervals to-date.

 

- Drillhole CIW-19 returned two main lithium-mineralized intercepts of 53.1m averaging 0.35%Li2O (25-78.1m) and 144m averaging 0.37%Li2O (85-229m), with a high-grade interval of 10.8m@0.71% Li2O (103-113.8m).

 

- Drillhole CIW-20 returned three main mineralized intercepts: 98m averaging 0.35%Li2O (28-126m), 16.85m averaging 0.33% Li2O (132.15-149m) and 60m averaging 0.49%Li2O (154-214m), with the latter containing high-grade intervals of 9m@0.67%Li2O (160-169m) and 12.1m@0.85%Li2O (174-186.1m).

 

- Significant tin and tungsten mineralization was intersected in upper part of both drillholes: 3.1m@0.20%Sn and 0.021%W, 4.75m@0.13%Sn and 0.015%W, 2.45m@0.17%Sn and 0.003%W and 1.35m@0.122%W and 0.07%Sn in drillhole CIW-19;  3m@0.37%Sn and 0.003%W, and 1m@0.36%Sn and 0.004%W in drillhole CIW-20.

 

- Drilling continues in the western part of the Cinovec deposit (targeting high-grade zones near the rhyolite/granite contact) and in the central part (targeting near-surface mineralization on the flanks of the historic underground mine). Altogether, eight drillholes have been completed this year (2,791m) with three other underway at this time.

 

European Metals CEO Keith Coughlan said:

This year’s drilling programme has yielded excellent results. During the year we have continued to verify the historic drilling and also, have identified high-grade drill intersections in areas that there has been relatively little historical work. The shallow lithium intercepts that extend significantly beyond historical workings, combined with the substantive tin and tungsten intercepts, we believe, will have a positive effect on the economics of the project. With three drill rigs operating targeting high-grade zones and metallurgical test work almost complete, we look forward to updating the market as the project advances up the development curve and towards potential commercialization”. 

 

Drill Programme

 

The drillholes CIW-19 and CIW-20 are located in the central part of the Cinovec, near the Central Shaft where high-grade tin and tungsten veins were mined in the past.  The current drill programme at Cinovec Main has been planned to confirm and delineate near surface lithium and tin mineralisation that would provide initial feed to the mill. Other goals are the conversion of resources from the Inferred to Indicated category, and delivery of material for metallurgical testing.  So far, eight diamond core holes have been completed, and three are underway.  Visual inspection and logging indicates that the geology in these holes is as expected. Drill details are listed in Table 1 below.

 

After geological logging, drill core is cut in half with a diamond saw.  Quarter core samples are selected (honouring geological boundaries) and dispatched to ALS (Romania) for preparation and assay; the 3/4 of the core is returned to the core box and stored securely on site.  Samples are being prepared and analysed by ALS using ICP and XRF techniques following standard industry practice for lithium and tin deposits.  Strict QAQC protocols are observed, including the insertion of a Li standard in a random fashion for every 10 core samples.

Mineralized Intercepts and Lithology in CIW-19 and CIW-20

 

The drillholes CIW-19 and CIW-20 are collared in altered granite near the historic mine shaft. This geological domain is characterized by the presence of quartz veins flanked by relatively narrow li-mica veneers, hosted in variably altered and mineralized lithium granite. Most of the quartz veins were mined out in the past. The drillholes hit several open stopes after vein mining.

 

This geological domain also has a distinct geochemical signature in that the vein-hosting granite is continuously enriched in tin.  So in  CIW-19 the upper 170 meters average 0.042%Sn (median 262ppm), and 155m@0.044%Sn (median 260ppm) in CIW-20, respectively. 

 

The vein set is underlain by greisenized granite with greisen intervals well mineralized with lithium.

 

In the lowest parts of the drillholes, unusually elevated grades of niobium and tantalum were recorded, with the best individual samples of 510ppm Nb and 212ppm Ta (CIW-20).

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 49.1Mt @ 0.43% Li2O and an Inferred Mineral Resource of 482Mt @ 0.43% Li2O containing a combined 5.7 million tonnes Lithium Carbonate Equivalent.

 

This makes Cinovec the largest lithium deposit in Europe and the fourth largest non-brine deposit in the world.

 

Within this resource lies one of the largest undeveloped tin deposits in the world, with total Indicated Mineral Resource of 15.7Mt @ 0.26% Sn and an Inferred Mineral Resources of 59.7 Mt grading 0.21% Sn for a combined total of 178kt of contained tin. The Mineral Resource Estimates have been previously released on 18 May 2016. 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. 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 percent lithium oxide (Li2O) content or percent 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 below to get an equivalent Li2CO3 value in percent. 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 532Mt @ 0.20% Li grade (as per the Competent Persons Report dated May 2016) 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:
