Foremost Lithium Completes Exploration Program in Preparation of Upcoming Drill Season

Highlights Include:

• 19-day mapping and sampling program on its Lithium Lane properties has resulted in the collection of seventy-one (71) pegmatite samples
• “MMI” (Mobile Metal Ion) survey was conducted on the Peg North property where a further 174 samples were collected to test for geochemical anomalies that may indicate the presence of subsurface pegmatites from a large 3KM magnetically depleted zone
• Zoro Dyke 1 was revisited to collect information for detailed mapping and collection of samples to assist with targeting for a proposed drill program; Eight (8) pegmatite samples, five (5) which contained visible spodumene were collected for assay
  

VANCOUVER, British Columbia, Sept. 11, 2023 (GLOBE NEWSWIRE) -- Foremost Lithium Resource & Technology Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost Lithium”, “Foremost” or the “Company”), a North American hard-rock lithium exploration company, has completed an extensive summer exploration program on its “Lithium Lane Properties”, near the historic mining center of Snow Lake, Manitoba.

Dahrouge Geological Consulting Ltd. (“DGC”), has conducted a large-scale surface exploration program on Foremost’s four Lithium Lane properties for Lithium Cesium Tantalum (“LCT”) pegmatites including:

• Prospecting and rock sampling for geochemical analysis, focused on predefined priority targets
• Detailed geological mapping in highly prospective areas
  
• Systematic Mobile Metal Ion (MMI) geochemical grid covering structural areas-of-interest on the Peg North Property.

DGC has applied its established targeting methodology to Foremost’s extensive geological database, integrating historical and recent exploration records to highlight high-priority targets. The program’s focus includes properties that are either under-explored or have good potential for discovering additional LCT pegmatites.

“The initial exploration from DGC covering all four properties has gone exceedingly well,” said Jason Barnard, President and Chief Executive Officer of Foremost Lithium. “This approach including both geological and prospecting evaluations, combined with onsite rock geochemistry, will enable us to be well-positioned to have high-priority targets this coming drill season. We are focused on advancing our lithium project to the next phase while we work to build long-term shareholder value.”

Summary of 2023 Exploration Program

Dahrouge Geological Consulting Ltd., on behalf of Foremost Lithium, completed a 19-day mapping and sampling program on their Lithium Lane properties that resulted in the collection of seventy-one (71) pegmatite samples. Seven (7) samples were collected from spodumene-mineralized pegmatite and the remaining sixty-four (64) from granitic pegmatite to broaden the understanding of the source-rock relationships, and zonation of the pegmatite. Additionally, a systematic MMI survey was conducted on the Peg North property to assess the nature of the magnetically depleted zone associated with a substantial north-trending sinistral fault and its potential as a pegmatite conduit. From this, 174 samples were collected to test for geochemical anomalies that may indicate the presence of subsurface pegmatites.

All samples have been submitted to SGS Laboratory in Burnaby for analysis, with results anticipated in the coming weeks.

Peg North Property

At the Peg North Property, the historically mapped pegmatites were mapped and sampled. This work verified the original 1949 mapping by the Geological Survey of Canada. Further exploration on the Peg North property uncovered an additional forty-five (45) pegmatites that were mapped and sampled. Additionally, 174 MMI samples were collected from the area of a large magnetically depleted zone that occurs at the southern end of the previously unrecognized sinistral fault structure identified by Foremost Lithium’s recent UAV-assisted magnetic survey.

Grass River Claims (GRC) Property

At the GRC Property, the historically mapped pegmatite outcrops were mapped and sampled with eleven (11) samples collected from visible, granitic pegmatite exposures. This verified the 1950s exploration work undertaken on the property, verified in the assessment files housed in the office of the Manitoba Mining Recorder and subsequently mapped by the Manitoba Geological Survey.

Jean Lake Property

At the Jean Lake Property, the mapped individual spodumene-pegmatite occurrences (B1, B2, and B3) that collectively have been referred to as the “Beryl Pegmatite” were sampled and mapped in further detail to assist with drill targeting for the upcoming drill season. This verified the presence of mineralized spodumene-pegmatite originally re-discovered during Foremost Lithium’s 2021 The 2021 program, which consisted of five (5) rock chips samples, two (2) of which were from the B1 spodumene-pegmatite occurrence which returned assays of 3.89% and 5.17% Li₂O (see press release dated October 28, 2021) The 2023 exploration campaign returned four (4) samples, three (3) of which were from spodumene-bearing pegmatite at the B1 and B2 occurrences.

Zoro Property

At the Zoro Property, the mapped spodumene occurrence “Dyke 1” was revisited for sampling and detailed mapping to assist with targeting for a proposed drill program. This verified the presence of spodumene-mineralized pegmatite on surface at Dyke 1. Eight (8) pegmatite samples, five (5) of which contained spodumene, were collected for assay.

Next Steps – Drilling and Enhanced Field Program

Preparations have now commenced for an upcoming drill campaign on all four properties, marking a pivotal phase in the projects’ advancement. The field program will also be enhanced to incorporate channel sampling and higher-resolution mapping and sampling to advance Foremost Lithium’s understanding of the geological landscape.

The results from the 2023 summer exploration program, coupled with regional/local geological assessments, historical data, and high-resolution geophysics have all been essential inputs and have enabled an efficient and effective drill targeting strategy. Drilling is planned for Q1 2024.
