United Lithium Discovers Three New Spodumene Pegmatites – Drilling Returns 1.92% Li?O over 26.8 m and 1.54% Li?O over 28 m at Bergby, Sweden

VANCOUVER, Nov. 21, 2023 - United Lithium Corp. ("United" or the "Company") (CSE: ULTH; OTC: ULTHF; FWB: 0ULA) reports the first set of diamond drilling results from its 2023 Drill Program at the Bergby Lithium Project ("Bergby" or the "Project"). Prospecting and subsequent drilling during 2023 have discovered two new high-grade spodumene-bearing pegmatite bodies, Pegmatites "D" and "E," bringing the total drilled on the Project to five. Bergby is a 100%-owned, district-scale, hard rock lithium project covering 10,828 hectares ("ha") near great infrastructure and the coast of the Gulf of Bothnia in Central Sweden. The Project hosts numerous LCT (lithium-cesium-tantalum enriched-type) granitic pegmatites, five of which have been drill-confirmed. The 2023 Drill Program is ongoing, with further results pending, and has been expanded from 4,000 metres ("m") to 6,000 m due to the encouraging results. The Company will host a webinar on November 29^th, 2023, at 1:15 pm PST (Register Here).

Highlights:

• Five spodumene-bearing pegmatites drill-confirmed at Bergby to date, with a collective strike length of 4,000 m and thickness up to 24 m;
• Drilling assay results for Pegmatite D include:
  • 1.92% Li₂O over 26.80 m from 3.60 m depth down hole (hole BBY23132);
  • 1.54% Li₂O over 28.01 m from 9.12 m depth down hole (hole BBY23135);
  • 1.82% Li₂O over 12.97 m from 14.05 m depth down hole (hole BBY23138); and
  • 1.96% Li₂O over 9.68 m from 38.87 m depth down hole (hole BBY23141).
• New discoveries Pegmatite D and Pegmatite E currently being drilled; and a sixth, Pegmatite F, discovered in an outcrop, yet to be drilled;
• Fully funded drill program expanded by 50% to 6,000 m continuing into Q1 2024;
• Newly identified pegmatite outcrops and several unsourced spodumene-bearing pegmatite boulder trains remain to be further explored, and
• Much of the district-scale project is yet to be explored.

"Today's results are very exciting, and with the diamond drilling ongoing at Bergby, we are encouraged at the prospect of further discoveries," stated Scott Eldridge, United's President and CEO. "Bergby is encircled by world-class mining infrastructure including highway, power, rail, port and a nearby labour and logistics hub. Given the European Union's push to develop its own EV/battery industry and downstream battery metals supply chains, domestic lithium discoveries will prove valuable and we look forward to further results as we attempt to unlock the blue-sky potential of Bergby and our other Scandinavian projects."

"This is a thrilling time for the team as we continue to make new discoveries at Bergby," stated Cathy Fitzgerald, United's Executive Vice President, Exploration. "In the last two months, we have expanded our technical team, all of whom are working hard to execute our strategic drilling program and deliver on identifying and defining new spodumene-bearing pegmatites. We are looking forward to not only further drilling results at Bergby, but an exciting 2024 as we continue to explore the property."

Drill Program Details

The 2023 Bergby Drill Program (the "Drill Program") commenced in April 2023 (see news release dated April 20, 2023) with a plan to complete approximately 4,000 m of diamond drilling across a proposed 50 drill holes. The Drill Program is designed to test newly identified spodumene-bearing outcrops and to further define spodumene-bearing bodies along strike, down dip and with infill holes. In conjunction with drilling, prospecting and surface sampling were undertaken to continue identifying new spodumene-bearing outcrops and boulders.

Based on the success of the 2023 Drill Program so far, drilling has been expanded to approximately 6,000 m and is expected to be completed in Q1 2024. To date, 4,291.50 m has been completed across 50 holes in newly discovered Pegmatites D and E. Of these, 44 intercepted pegmatite and 38 holes have confirmed spodumene (visually identified). Results are reported here for 14 drill holes (refer to Table 1 and Table 2), completed between mid-April and mid-June, 2023. Further assay results are pending for the remainder of Pegmatite D and Pegmatite E. The 2023 Drill Program is fully funded after completing a C$7 million private placement earlier this year (see news release dated March 6, 2023).

Pegmatites D and E lie 2,600 m and 3,200 m north northwest, respectively, from the first discovery, Pegmatite A, which was first drilled in 2017 by a previous operator (see Figure 1). Figure 1 highlights the modelled Pegmatite D system based on drilling to date and shows the 14 holes for which Li₂O assays have been received and reviewed. Photos of spodumene-bearing drill core can be viewed on the Company website at www.unitedlithium.com/sweden. All spodumene-bearing pegmatites drill tested at Bergby were identified by outcrop and boulder train mapping. Table 3 summarizes the pegmatite discoveries at the Bergby Project and their drill progress to date. All pegmatites remain open to depth and along strike, and several outcrops and unsourced spodumene-bearing boulder trains warrant drill testing. Additionally, at least one-third of the property remains unexplored using the Company's highly successful prospecting methods, highlighting the excellent potential at Bergby for further discovery.

Geology

The Bergby Project is situated within the Hamrånge synform in the west-central part of the Fennoscandian Shield. The stratigraphy in the area consists of mica schist overlain by 1.88 billion years ("Ga") old felsic and mafic volcanic rocks, followed by metaquartzite (< 1.86 Ga) believed to have formed during an 1.86-1.83 Ga intra-orogenic phase. Geological and isotopic data suggests an oceanic island arc signature of the metavolcanic rocks. The surrounding 1.86 Ga granitoids of the Ljusdal Batholith is believed to have been formed in an active continental margin setting. When not covered by till (typically less than 3 m depth), extensive pegmatite boulders and outcrops have been found on the Project. The strike of pegmatites follow the general trend of host rock foliation, NNW-SSW. All five drilled lithium-mineralized pegmatites at Bergby are spodumene bearing, with Pegmatite A also containing petalite. Pegmatite A displays a shallow 20° dip to the WNW, whereas the other four bodies (B, C,D and E) are more subvertical (at ~65° to 88°).

Project History

Spodumene-bearing pegmatite boulders were first described in the area of the Bergby Project in 2006 during a university field mapping course. In 2016, the project area was claimed by Leading Edge Materials Corp. ("Leading Edge"), who later identified an extensive lithium and tantalum mineralized pegmatite boulder field leading to several mineralized outcrops. Samples from some of these outcrops returned up to 4.65% Li₂O and up to 803 ppm Ta₂O₅ (see Leading Edge's news release dated December 1, 2016).

Pegmatite A was drill-confirmed in 2017 by Leading Edge across two phases, with a total of 1,525 m completed in 33 holes, testing the body to 131 m depth and along 1,500 m strike length with the "discovery" hole returning 1.62% Li₂O over 10.45 m from 2.2 m depth down hole (hole BBY17005) (see Leading Edge's news releases dated April 25, 2017 and November 17, 2017). The modeled maximum true width of Pegmatite A is now 24 m, and it is drill defined down to 100 m below surface.

The Bergby Project was acquired by the Company in 2020 from Leading Edge, and drilling commenced on additional outcrop targets in late 2021. Between October 2021 and the end of 2022, the Company completed 9,511 m in 97 drillholes confirming two new pegmatites discoveries (Pegmatites B and C) and undertook further drilling on Pegmatite A. Highlights of drilling at Pegmatite B included 1.34% Li₂O over 47.75 m from 2.25 m depth down hole (hole BBY21069, estimated true width of 10 m - see news release dated January 20, 2022). A highlight of drilling at Pegmatite C includes 2.39% Li₂O over 2.03 m from 15 m depth down hole (hole BBY22128, estimated true width of 1.50 m - see news release dated May 23, 2023).

To date, 15,393.10 m of drilling in 180 holes has been completed at the Project.

Quality Assurance and Quality Control

Core drilling is being undertaken by Ludvika Borr Teknik AB, of Sweden, using 49 millimetres (equivalent to NQ2) diameter rods. United's field team log and sample all drill core samples in a secure core facility at the Company's operations building in Norrsundet, about 5 kilometres ("km") from the Project area. Core samples are cut in half longitudinally using a diamond cutting saw, and half cores submitted to ALS Ltd. ("ALS") facilities in Piteä, Sweden for preparation (Prep-31 package) with each sample crushed to better than 70% passing a 2 mm (Tyler 9 mesh, U.S. Std. No. 10) screen. A split of up to 250 grams is taken and pulverized to better than 85% passing a 75-micron (Tyler 200 mesh, U.S. Std. No. 200) screen. The samples are then forwarded to the ALS facilities in Loughrea, Ireland, an accredited mineral analytical laboratory (ISO/IEC 17025:2017 and ISO 9001:2015), for analysis using the ME-MS89L method (sodium peroxide fusion and HCL leach followed by ICP-AES and ICP-MS) with lithium (Li) reportable range between 2 and 25,000 ppm. This method analyzes for 53 elements and is considered appropriate for lithium-mineralized pegmatites.

Certified reference standards, duplicate and blanks are routinely inserted into the sample stream as part of United's quality control/quality assurance program ("QA/QC"). No QA/QC issues were noted with the results reported herein. The Company's Qualified Person is of the opinion that the sample preparation, analytical, and security procedures followed are sufficient and reliable. The Company is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data reported herein. All drill intercepts reported are down-hole core lengths.
