THE DRILL SERGEANT: Lithium Australia (ASX: LIT) claimed verification of cobalt-copper-lithium mineralisation from exploration fieldwork undertaken within the company’s fully owned Eichigt project in Germany.
Lithium Australia said cobalt and copper mineralisation has been encountered in the field with grades of up to 1.47 per cent for cobalt and 0.54 per cent for copper present in Eichigt field samples.
The company highlighted that lithium results from this exploration activity at the project were also elevated – critically, within weathered material – with grades of up to 0.71 per cent lithium oxide (Li2O) received.
LIT declared these results for cobalt and copper confirm polymetallic mineralisation encountered previously within the Eichigt project area, adding that deleterious elements, including arsenic and uranium are very low in concentration.
The cobalt has shown to occur in association with iron-and manganese-as part of a polymetallic gossan formed at surface above an extensive vein system. The oxides are enriched in lithium.
Lithium Australia noted this style of mineralisation has not been previously described in the region.
“The results of the first exploration campaign at Eichigt strongly supports our view that the license area we applied for was neglected during systematic exploration work carried out during the time of the GDR,” Lithium Australia managing director Adrian Griffin said in the company’s announcement to the Australian Securities Exchange.
“The combination of cobalt, lithium and copper is an indication of the genesis of the mineralised system and the strong possibility of finding source granites and greisen style mineralisation we see nearby at Sadisdorf.
“The historic diggings indicate the strike extent, albeit remaining open.
“The down-dip extensions will be evaluated after delineation of the extent of surface mineralisation.”
The company was granted the 133 square kilometre Eichigt exploration licence in January this year, adding to its existing Sadisdorf project, also in Saxony.
Lithium Australia is farming into a joint venture (JV) with German company Tin International AG.
A 2012 JORC code-compliant Inferred Mineral Resource of 25 million tonnes at 0.45 per cent Li2O (at a cut-off of 0.3 per cent Li2O) was announced for the project in December last year.
Lithium Australia has stated its objective to establish a central processing hub in Europe to support battery production for the rapidly expanding electric vehicle industry.
The company plans to use its 100 per cent- owned SiLeach process to recover lithium from its German projects, should doing so prove economically feasible.
