United Lithium Corp. announced results of drilling from the Kietyönmäki Project in Finland. The Company completed approximately 1,450 metres of diamond drilling targeting the lithium-mineralized Main Dyke.

Drill-confirmed to be more than 200 m long, up to 25 m wide and extending to a depth of at least 160 m, the expansion of the Main Dyke remains open along strike to the southeast and at depth. The geology of the host rocks and pegmatite composition at Kietyönmäki are similar to that observed in the Kaustinen region of Finland, which hosts the Keliber Lithium Project, owned 85% by Sibanye-Stillwater Corp. The Keliber Project hosts 17 million tonnes at 1.02% Li2O according to its mineral resource estimate in its October 2022 Definitive Feasibility Study.

The 2022-2023 drilling program at Kietyönmäki comprised 13 diamond drill holes for a total of 1,449.40 m (refer to Table 1 for drill hole information), and the collection of 100 percussion drill hole samples completed between September 2022 and February 2023. The diamond drilling aimed to complete both infill and expansion drilling on the Main Dyke, whereas the percussion drilling targeted discovery outside the Main Dyke. The drill program was successful in expanding the drill-confirmed length of the Main Dyke from 60 m to approximately 205 m and in confirming the depth of the body to at least 160 m depth below surface.

Percussion drilling results highlight possible new pegmatites that warrant follow up drilling in 2024, with two occurrences located 100 m and 230 m southeast of the Main Dyke. The Main Dyke is spodumene and petalite bearing with some notable tin and tantalum mineralization with SnO2 values up to 4,228 ppm and Ta2O5 up to 691 ppm. Refer to Table 2 for diamond drilling results.

Lithium-mineralization commonly continues beyond the margin of pegmatite intercepts into wall rock with values up to 0.59 % Li2O in host mica schists and metavolcanics. Please refer to Figure 2 for a three-dimensional view and a cross section view of diamond drilling and modeled pegmatite bodies. United contractors conducted field prospecting and sampling contemporaneously with, and post-drilling across the main Kietyönmäki tenure.

A total of 44 surface samples were collected, and of these, 18 were outcrop pegmatite samples and 26 were boulder pegmatite samples. Three high-grade boulders samples returned values of 0.88% Li2O, 1.37% Li2O and 2.24% Li2O. Also, some notable tantalum and tin values were identified and all occurrences.

These, combined with some historically identified pegmatites, warrant follow up in a potential spring 2024 exploration program. A potential 2024 program may involve geophysical surveying, further prospecting and a soil and till geochemical and indicator mineral sampling program.
