REM takes larger stake in European Metals’ Cinovec deposit; Houston Lake sets sights on higher resource at Pak; and Korean researchers develop high-performing porous Li-ion battery.

UK-based Rare Earth Minerals Plc (REM) has increased its shareholding in European Metals Holdings Ltd to 9.61% from 6.65% held previously, making REM the ASX-listed lithium explorer’s largest shareholder.

The move gives REM a bigger stake in the Cinovec project in the Czech Republic, a lithium-bearing mica deposit, which is owned by European Metals and subject to a pending joint venture (JV) agreement with fellow ASX-listed, Lithium Australia (formerly known as Cobre Montana NL).

AIM-listed REM did not disclose the price it paid for the higher stake, but on 23 June it paid £200,000 ($308,770*) for its initial 6.65% stake, via a placement of new ordinary shares by European Metals.

Shares in European Metals were trading at around Australian dollar (A$) 0.13/share ($0.10/share) on the Australian Securities Exchange on 1 July, when the transaction took place and are presently hovering around A$0.15/share.

TSX-V-listed Houston Lake Mining Inc. has released the results of analysis on four infill drill holes at its Pak lithium pegmatite project in northwest Ontario.

The highlight of the results identified by the company was a 5.85 metre-wide lithium zone, grading at 4.15% lithium oxide (Li2O) from 80.5 metres to 85.9 metres. This formed part of a 66.05 metre intersection, grading at 2.02% Li2O.

Other grades ranged from 0.22% Li2O to 3.86% Li2O across lithium-enriched zones intersected across the four holes.

Houston Lake’s president, Trevor Walker, said that the results would positively expand the project’s current mineral resource estimate, which stands at 2.45m tonnes indicated at 1.81% Li2O and 5.91m tonnes inferred at 2.01% Li2O.

In technology news, researchers at the Center for Self-Assembly and Complexity at the Institute for Basic Science at Pohang University in South Korea have created a lithium-ion (Li-ion) battery made from a porous solid, which they say greatly improves the battery’s performance and reduces the risk of overheating.

According to the institutes Dr Kimoon Kim, the highly anisotropic proton conducting behaviours in porous electrolyte material in fuel cells are safer than solid lithium electrolytes.

The new battery is built from "pumpkin-shaped" molecules, organised in a honeycomb structure. The molecules have an extremely thin, one-dimensional channel for ion movement and the physical structure of the porous material enables the lithium ions to diffuse more freely than in conventional Li-ion batteries.

After four days of testing, the porous batteries showed no thermal runaway and hardly any change in conductivity, the researchers said.
