European Metals Holdings Limited (ASX & AIM: EMH) has this morning reported on its ongoing infill drilling program and given analytical results for the first drillhole CIS-4 at the Cinovec Lithium-Tin Project.
In addition, the Company is pleased to announce the appointment of Mr Craig Reimer as the Manager of its Definitive Feasibility Study.
HIGHLIGHTS
* Infill drilling continues in the southwest section of
the deposit, targeting two 'gaps' in the resource
model that could potentially be targeted for mining
in the initial years.
* Altogether, five out of 6 planned drillholes have
been completed this year, for a total of 2163.1m.
* Assays have been received for the first drillhole
CIS-4, which returned a continuous mineralized
intercept of 148.30m averaging 0.40%Li2O, starting at
297.7m drill string depth.
* In addition, the upper section of the main lithium
interval contains significant tin and tungsten
mineralization: 15.85 meters averaging 0.70% Li2O,
0.29% tin and 0.073% tungsten.
* Experienced Project Manager, Craig Reimer has been
appointed to head the Company's Definitive
Feasibility study.
European Metals Managing Director Keith Coughlan said, “We are very pleased with the drilling progress to date and the results for the first hole CIS-4 drilled this year. The lithium and tin mineralization intersected in the first hole is strong and continuous and will increase the size of our current inferred and indicated resource at Cinovec south. This will provide additional options for optimizing production and development schedule. I am particularly pleased with the strong tin and tungsten credits in this part of the Cinovec South deposit.
In addition, we welcome Craig Reimer as the Manager of the Definitive Feasibility Study. Craig is a hugely experienced Project Manager and has worked for numerous clients in Australia and overseas and has been involved with studies, commissioning and construction of large scale projects. Craig will head an excellent study team located in Australia and Czech that is focused on delivering a robust Study in H2 2018.
Drill Program
The current six-hole drill program at Cinovec South is planned to focus on infill drilling in two areas where data density is low and ‘gaps’ in the resource model occur. There are the expectations this will add to the high grade resource at Cinovec South in critical areas where mining will start. It will also assist in the conversion of resources from Inferred to Indicated category, and delivery of material for metallurgical testing. So far five diamond core holes have been completed, and one is underway.
The drill hole information is listed in Table 1 below, and their locations are shown on the sketch 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 random fashion for every 10 core samples.
Mineralized Intercepts and Lithology in CIS-4
The CIS-4 drill hole is collared in rhyolite in the eastern area of the Cinovec South deposit. The main characteristics is the presence of massive greisen/greisenized zone in granite just below its contact with the overlying rhyolite.
In CIS-4, the Li-mineralized greisen and strongly greisenized granite start immediately bellow the rhyolite/granite contact at a depth of 279.7m. Below the contact, variably altered granite with two major and several minor greisen zones were intersected. Underlying albite granite with lithium mica starts at 320.6m and continues to 338.9m drill string depth. The section from 338.9m up to 426m is formed mostly by greisenized Li-mica rich granite. The tin and tungsten mineralization is spatially associated with the strong to pervasive greisen style alteration in the upper 75.3m of the hole. If no Sn cutoff is applied, the interval grades 0.14% Sn, 0.035%W and 0.42% Li(2) O.
Table 2 below provides summary of the results. According to the geological and block model the greisen bodies (and the mineralized zones) dip to the south, although this fact could not be fully confirmed by core angles observations in the core. The CIS-4 drillhole was angled 16.6 degrees toward NE, with dip -84.6 and the reported intercepts appear close to true thicknesses.
