United Lithium Increases Ownership of Kietyönmäki Lithium Project in Finland to 100% - Seite 2

Kietyönmäki was discovered by the Finnish Geological Survey (“GTK”) in the mid-1980’s. GTK drilled 17 shallow diamond drill holes testing to 70 meters (“m”) below surface across three traverses, including one traverse of very shallow holes to locate bedrock. In 2016, six holes were drilled by Sunstone Metals Limited which intersected lithium mineralization hosted within a spodumene-bearing pegmatite dyke swarm. Since acquiring the Project, the Company has completed 1,450 m of drilling in 13 holes, primarily testing the lithium-bearing Main dyke.

Drilling highlights to date are:

• 1.53% Li₂O over 23.00 m (hole R307) drilled by GTK¹;
• 1.31% Li₂O over 24.25 m (hole R310) drill by GTK¹;
• 1.44% Li₂O over 24.17 m from 17.88 m downhole (KMDD001) drilled by previous operator²;
• 1.52% Li₂O over 25.95 m from 33.70 m depth downhole (ULDH-3)³ and
• 1.45% Li2O over 29.50 m from 69.1 m depth downhole (ULDH-4)³.
  

The Main Dyke has now been drill-defined to be up to 25 m wide and more than 200 m length and confirmed to extend to at least 160 m depth below surface. This dyke is hosted in an assemblage comprising mica schists, metavolcanics and amphibolite gneiss with rare feldspar porphyry intrusives. Mica schists are altered to chlorite and biotite and commonly contain altered (to chlorite) andalusite and more rarely garnet. There is variable till cover (up to 3 m) and boulder occurrences are present across the Project.

Kietyönmäki has similarities geologically to the Kaustinen region of Finland, which hosts the Keliber Lithium Project (“Keliber”), owned 85% by Sibanye-Stillwater Corp. Keliber hosts an estimated 17 million tonnes at 1.02% Li₂O in its mineral resource estimate, as disclosed in its October 2022 Definitive Feasibility Study⁴. Keliber is currently under construction with a targeted 15,000 tonnes per annum battery grade LiOH production capacity.
