Foremost Lithium Returns 2.13% Li2O and 1.86% Li2O in Samples from its Zoro and Jean Lake Properties and Begins Preparation for Winter Drill Program

Highlights Include:

• Initial phase of rock sampling return assay of up to 2.13% Li₂O at the Zoro Lithium Project and values of up to 1.86% Li2O at Jean Lake Lithium Project
• Jean Lake Property displayed promising lithium mineralization with significant upside potential.
• Zoro Project presents further potential to delineate future resources on spodumene-bearing dykes.
  

VANCOUVER, British Columbia, Oct. 12, 2023 -- Foremost Lithium Resource & Technology Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost Lithium", "Foremost" or the "Company"), a North American hard-rock lithium exploration company, today announced positive results returned from the rock sampling program on its Peg North, Grass River Claims, Jean Lake, and Zoro properties, including high-grade lithium values and spodumene mineralization at both the Zoro and Jean Lake Property.

Dahrouge Geological Consulting Ltd. ("DGC") conducted a large-scale surface exploration program on Foremost's four Lithium Lane properties for Lithium Cesium Tantalum ("LCT") pegmatites this past summer, focusing interest towards pre-defined, high-priority targets on the Zoro and Jean Lake Property.

"The compilation of work has yielded highly promising results from sampling to date, and the team at Dahrouge continues to demonstrate their ability to execute a successful exploration program," said Jason Barnard, President and Chief Executive Officer of Foremost Lithium. "Our 2023 exploration campaign is focusing on our high-quality assets and is supported by extensive geological data. The potential of this fertile area gives us great confidence as we define drill targets in preparation in this upcoming drill program. We look forward to proving results for our company and our shareholders."

Samples were shipped to SGS Laboratories (Burnaby) for analysis which used a total dissolution of the sample by sodium peroxide fusion and ICP-MS finish. This analytical approach is the standard analytical technique used by the Company on its Zoro and Jean Lake lithium projects. QAQC samples were inserted into the sample sequence at a rate of 5%, utilizing certified reference material and quartz blanks.

At the Zoro Property, the mapped spodumene occurrence at Dyke 1, was revisited for sampling and detailed structural mapping to assist with targeting for the upcoming winter drill season. This was revisited for sampling and hosts an inferred resources of 1,074,567 tons at a grade of 0.91% Li2O, with a cut-off of 0.3% in accordance with the Company's SK-1300 Technical Report Summary (2023) and NI-43101 Technical Report (2018). DCG verified the presence of spodumene-mineralized pegmatite on surface at Dyke 1. Eight (8) pegmatite samples, five (5) containing spodumene, were collected for assay. Assay highlights can be found in Table 1.

Jean Lake Property

Spodumene-pegmatite occurrences (B1, B2, and B3) that are collectively known as the "Beryl Pegmatites" were sampled and mapped in further detail to assist with drill targeting for the upcoming drill season. Additional overburden was stripped from the B1 and B2 occurrence, revealing more spodumene mineralization. Four (4) chip samples were collected during the 2023 field program, three (3) of which were from spodumene bearing pegmatite. Samples taken from the B1 pegmatite hosted coarse-grained, pale green spodumene that ranged from 5cm to 0.70m (Photo 1). Samples taken from the B2 pegmatite hosted abundant apple-green to yellow-green spodumene that ranged from 5cm to 15cm (Photo 3). Assay highlights are presented in Table 2 below.

Next Steps - Winter Drill Program

Steps towards applying for a work permit and drill targeting are currently underway for a winter drill program in the coming months on both the Zoro and Jean Lake Properties. Drilling on Zoro will seek to expand the existing resource on Dyke 1, as well as further investigate the spodumene-bearing pegmatites on Dyke 8 and Dyke 16. The drill program at Jean Lake will follow up on the results from the winter 2023 drill program with the hopes of expanding the high-grade spodumene occurrences at B1 and B2.
