Kietyönmäki Project, Finland
Vancouver, British Columbia
October 19, 2023 – United Lithium Corp. (CSE: ULTH ; OTC: ULTHF ; FWB: 0ULA) (“United” or the
“Company”) is pleased to announce results of drilling from the Kietyönmäki Project (“Kietyönmäki “ or
the “Project”), in Finland. The Company completed approximately 1,450 metres (“m”) 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.1
Highlights
• High-grade lithium oxide results include:
o 1.52% Li2O over 25.95 m from 33.70 m depth down hole in hole ULDH-3; and
o 1.45% Li2O over 29.50 m from 69.10 m depth down hole in ULDH-4.
• This new drilling builds upon positive historical drill results from previous operators including:
o 1.53% Li2O over 23 m drilled by the Finnish Geological Survey (“GTK”); and
o 1.10% Li2O over 42 m by previous operator Sunstone Metals Ltd. (“Sunstone”).
• Drilling confirmed the extent of the Main Dyke to be greater than 200 m in length and extending
to at least 160 m depth, while remaining open along strike to the southeast and open at depth;
• Percussion drilling indicates that lithium -mineralized pegmatite is present as far as 230 m
southeast of the Main Dyke outcrop;
• Boulder sampling recovered lithium-bearing pegmatite samples ranging from 0.88% Li2O to 2.44%
Li2O. Pegmatite intercepts from percussion drilling and these boulder samples are expected to be
followed up in early 2024 exploration work to generate drill targets; and
• Recently increased land package at Kietyönmäki to approximately 21,000 hectares (“ha”).
Scott Eldridge, United’s President, and CEO stated: “We are pleased to release United’s maiden drill results
in Finland. Previous operators had delivered encouraging results and we have now extended the known
mineralized boundaries of the M ain Dyke, w hich remains open. The Project has tremendous upside
potential exhibited by high-grade lithium bearing boulders that are not yet explained. Of note, the Keliber
Lithium Project was firs t discovered by identifying such boulders . The Kietyönmäki P roject now has a
district scale footprint with the recent addition of 20,000 hectares.”
Drill Program Details
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 (Figure 1) . The diamond drilling aimed to
complete both infill and expansion drilling on the Main Dyke, whereas the percussion drilling target ed
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
2
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. Select drill core photos are shown in Figure 3.
Prospecting and Further Work Plans
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 (Figure 4 ). 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. More details will be shared once program design is finalized.

Geology
The Kietyönmäki Project is situated within the Häme belt which comprises mainly amphibolites and mica
schists intercalated with greywackes and metapelites of the Forssa Volcanic Suite (1.9 -1.7 billion years
old). The succession has been intruded by gabbros, diorites, granodiorites, tonalites and later by K-
granites as well as pegmatites. Rocks in the region have been metamorphosed to lower amphibolite-facies
conditions. The Kietyönmäki dyke swarm is composed of several near -vertical dipping spodumene (as
spodumene-quartz intergrowths) and petalite-bearing pegmatite dykes, the largest being the Main Dyke.
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 Kausti nen region of Finland, which hosts the Keliber
Lithium Project, 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 Study .1
Keliber is currently under construction with a targeted 15,000 tonnes per annum battery grade LiOH
production capacity.1

Work History
The Project was acquired in early 2022 (see news release dated February 14, 2022) via a transaction with
a consor tium 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 b y 535 ha ( see news release dated
September 14, 2022), increasing the total land package to 900 ha. In 2023, United acquired a clai m
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 GTK. Their work
identified the pegmatite dyke swarm and provided an initial test of the largest body, (the Main Dyke) via
17 diamond drill holes ( 734 m), channel samples along nine profile line s and a ground magnetic survey.
Diamond drilling was completed along three sections and was shallow, at no deeper than 70 m depth
below surface. GTK drill-defined the Main Dyke to approximately 20 m width and approximately 50 m
Main Dyke

length, extending this to 120 m length with the addition of their channel sampling results. Some notable
drilling results include 1.31% Li2O over 24.25 m from 58.75 m depth down hole (hole R310) ; 1.66% Li2O
over 13 m from 86.00 m depth down hole (hole R3 16); and 1.53% Li2O over 23 m from 14.10 m depth
down hole (hole R307).
In 2016, previous operator Sunstone Metals 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% Li2O over 42 m from 17.88 m depth down hole (hole KMDD001).
Quality Assurance and Quality Control
Core drilling was completed using a GM200 rig, drilling NQ -diameter core by Mitta Oy of Oulu, Finland.
Diamond drilling samples were logged, photographed and samples selected for analyses were cut in half
before being labeled and securely shipped to ALS Scandinavia AB (“ALS”) in Piteå, Sweden for preparation.
Once prepared, samples were securely shipped by ALS to their laboratory in Loughrea, Ireland for analysis.
Samples were analysed by the ME -MS81 method (lithium borate fusion followed by ICP -MS) and ME-
4ACD81 (base metals by four acid digestion ). 28 of the samples were re -assayed by method ME -MS89L
(super trace sodium peroxide fusion followed by ICP-MS) to ensure high values of lithium were captured,
as ME-MS81 has an upper limit of 10,000 ppm for lithium. Standards and blanks were inserted into the
sample stream at regular intervals (10 blanks, 13 standards out of 169 total assays). After preparation, 17
duplicate samples were sent by ALS to CRS Labora tories in Kempele, Finland for QAQC checking.
Percussion drilling was completed using a GM1000 rig also by Mitta Oy. Samples were described and those
that intersected pegmatite were sent for preparation to ALS in Piteå. Once prepared pulps were securely
shipped by ALS to their laboratory in Loughrea, Ireland for analysis by the ME -MS89L method. Surface
rock samples were described in detail after collection, site locations were recorded and samples were sent
to ALS Scandinavia AB in Pite å, Sweden, with final pulps produced at ALS in Rosia Montana, Romania.
Once prepared, pulps were securely shipped by ALS to their laboratory in Loughrea, Ireland for analysis
by method ME-MS89L.
