Foremost completes 2025 drill program at Jean Lake

Executive Summary

• Foremost Clean Energy Ltd. has completed its 2025 diamond drill program at the Jean Lake gold-lithium property in Manitoba, consisting of 15 holes totaling 2,266 meters.
• The company has initiated a strategic core resampling program focusing on high-priority intervals from its 2023 drill program to enhance the geological model and understand mineralization continuity.
• Assay results from four of the 2025 holes have been reported, while results from the remaining 11 holes are pending; future drilling plans for 2026 will be guided by an updated geological model integrating all new and historical data.

Key Details

• 2025 Drill Program Completion:
  • Total holes drilled: 15 (JL25-001 to JL25-015).
  • Total meters drilled: 2,266 meters.
  • Location: Jean Lake gold-lithium property, near Snow Lake, Manitoba.
  • Purpose: Follow up on 2023 program, expand understanding of near-surface gold system along the Valkyrie trend, and test spodumene-bearing B1 pegmatite.
• Assay Status:
  • Results reported: 4 holes.
  • Results pending: 11 holes (JL25-005 to JL25-015).
• Core Resampling Program (2023 Core):
  • Objective: Obtain comprehensive data set to enhance geological model, fill geological gaps, and clarify gold continuity/grade distribution.
  • Focus: High-priority drill core from 2023 program, specifically adjacent to known high-grade intercepts.
  • Holes selected for resampling: 6 from the Valkyrie trend and 1 from the Midas trend.
  • Specific Historical Highlights being resampled:
    • FM23-08 (Valkyrie Trend): Previously returned 102 g/t gold over 0.5 meters, within 7.50 g/t gold over 7.66 meters.
    • FM23-25 (Midas Trend): Previously returned 6.86 g/t gold over 0.54 meters, within 2.07 g/t gold over 3.49 meters.
• Next Steps:
  • Upon receipt of all outstanding assays and resampling data, Foremost will update its geologic and structural model.
  • The updated model will combine 2023 discovery holes, all 2025 assay results, and new resampling data.
  • The model will refine priority targets along the Valkyrie and Midas trends to guide an expanded drill program anticipated for 2026.
• Upcoming Event:
  • CEO Jason Barnard to present at RedChip's Metals & Mining Virtual Investor Conference on Thursday, Dec. 11, 2025, at 2:30 p.m. ET.

Notable Quotes

• Jason Barnard, President and CEO: "The completion of our 2025 drill program successfully adds another 2,266 metres of data to the Jean Lake story. While we await these new assays, we are taking the pro-active step of resampling high-priority 2023 core from intervals adjacent to known high-grade intercepts, like the 102 grams per tonne gold in FM23-08. This cost-effective program is designed to fill in geological gaps and has the potential to positively impact our understanding of the mineralized system's scale and continuity. Integrating this new data with all past and pending results will allow us to build the most robust geological model possible as we plan for future drilling."
