European Metals Holdings announce analytical results for two drill holes from the recently-completed drilling in the Cinovec Main sector on Friday.
The AIM-traded company said the results confirmed or exceeded the expected lithium content and mineralisation widths.
Additionally, it confirmed that the Cinovec South Resource has now been added to the Czech State resource register, which it described as the first step in the process for the granting of a mining permit.
At Cinovec Main, EMH said hole CIW-22 contained the best lithium intercept to date from the company's drill programme of 264.5 m averaging 0.54% Li2O.
That hole also contains significant tungsten, tin, niobium and tantalum mineralization, with the best interval between 238m to 240m averages 0.86% Li2O, 0.41% Sn, 2.92% W, 868ppm Nb, and 150ppm Ta.
The tungsten grade in particular was significantly higher than expected, the board explained.
Hole CIW-26 returned an interval of 236.25m averaging 0.49% Li2O - including high-grade intervals of 16m @ 0.99% Li2O, 3m @ 1.15% Li2O, 2m @ 1.34% Li2O, 2m @ 0.99% Li2O, 1.3m @ 1.72% Li2O, 2m @ 0.93% Li2O, and 5m @ 0.84% Li2O.
Drill hole CIW-26 is located at the western edge of the deposit near the contact of the mineralisation, it said, and drillhole CIW-22 is located in the central part of Cinovec Main.
EMH said all remaining analytical results from the programme would be released next week.
Geological information from all 17 drill holes had now been compiled into the Cinovec database, serving to update the geological model for Cinovec Main.
The board said the geologic model would be used to constrain and update the current block model in early February when all analyses would be available.
It said the block model and resource calculation would then be part of the pre-feasibility study.
"I am pleased to report results from two additional drill holes from the recently completed drilling program at Cinovec Main," said CEO Keith Coughlan.
"These results are excellent in terms of lithium grades and length of mineralised intervals.
"In addition, we are pleased to have been informed that subsequent to a submission we made to the State Authority, the Cinovec South resource estimate was approved by a committee of experts and placed on the State Register of mineral deposits."
Coughlan confirmed that was a prerequisite for receiving a mining permit.
"We already applied for the 'preliminary mining space' for Cinovec South, immediately after the resource calculation for Cinovec South was accepted to the State Register."
