United Lithium Corp. announced that it has increased its land position at the Kietyönmäki Project (the "Project") in Finland by approximately 20,000 hectares ("ha"). A new claim reservation was made approximately 6 km southeast of the main Kietyönmäki tenure, covering one known lithium-caesium-tantalum pegmatite with historical sampling of 2% Li(2) O. This area is highly prospective for further LCT pegmatite discoveries.

The Main Dyke, within the original 900 ha Kietyönmäki parcel, historically returned strong drill results encouraging United to increase its holdings in the region. The Company expects to release the final results from the 2022-2023 drilling program at Kietyönmäki in the coming weeks. United anticipates the results from the 2022-2023 drill program comprised of 13 diamond drill holes (1,449.60 m) and 100 shallow exploration percussion drill holes (296.40 m) to be released in the coming weeks.

The diamond drilling program aimed to complete both infill and expansion drilling on the Main Dyke, whereas the percussion drilling targeted discovery outside the Main Dyke area. The new claim reservation comprises 20,170 ha (approximately 200 square kilometres ("km")) 6.1 km to the southeast of the main Kietyönmäki exploration permit area. This region was acquired because there are known lithium and tungsten-bearing pegmatites here and the structure interpreted to be associated with the emplacement of the Main Dyke extends into this area.

Further, this region is relatively under-explored, easily accessible and has known S-type granites on the property. The known Li-bearing occurrence, Mikkola, was identified and sampled in the 1980's by a company active in the area at the time and returned 2% Li(2) O from a 5-10 m wide body. Geologically, this area is highly prospective for identifying new LCT pegmatites.

United will conduct an initial field prospecting and outcrop sampling program on the high priority areas on the new ground with the goal of identifying drill targets. Areas that are most highly prospective will be converted to an exploration permit area at the appropriate time. The Kietyönmäki Project is situated within the Häme belt which comprises mainly amphibolites and mica gneisses intercalated with greywackes and metapelites of the Forssa Volcanic Suite (1.9-1.7 billion years old).

The succession has been metamorphosed and was intruded by gabbros, diorites, granodiorites, tonalites and the youngest magmatic rocks, K-granites as well as pegmatites. The Kietyönmäki dyke swarm is composed of several petalite and spodumene-bearing pegmatite dykes, the largest being the Main Dyke. There is sporadic thin till cover and boulder occurrences across the Project.

United acquired the Project in early 2022 via a transaction with a consortium to purchase 83.6% of the issued and outstanding share capital of the private entity, Litiumlöydös Oy, which holds a 100% interest in the licenses that comprise the Project. Following the completion of this transaction, the Company expanded the Project by 535 ha, bringing the total land package to 900 ha. In 2023, United acquired the new claim reservation over a new parcel located 6.1 km to the southeast of Kietyönmäki, referred to as Salkola, covering 20,170 ha, bringing the total size of the Project to 21,070 ha.

The lithium-bearing pegmatites at Kietyönmäki were discovered in the mid-1980's by the Finnish Geological Survey ("GTK"). Their work identified the pegmatite dyke swarm there. The survey conducted an initial test of the largest body, the Main Dyke, drilling 17 diamond drill holes (734 m), channel sampling along nine profile lines and running a ground magnetic survey.

Diamond drilling was completed along three sections and was shallow, penetrating no deeper than 70 m depth below surface. They drill-defined the Main Dyke, identifying a 20 m width and approximately 50 m length, extending to 120 m length with the addition of their channel sampling results. Some notable drilling results include 1.31% Li(2) O over 24.25 m from 58.75 m depth down hole (hole R310); 1.66% Li(2) O over 13 m from 86.00 m depth down hole (hole R316); and 1.53% Li(2) O over 23 m from 14.10 m depth down hole (hole R307).

In 2016, previous operator Avalon, completed six diamond drill holes (1,172 m total) which further tested the Main Dyke along the same section lines that GTK had drilled (infill drilling). The most significant intersection was 1.10% Li(2) O over 42 m from 17.88 m depth down hole (hole KMDD001).
