Laurion starts drill program at Ishkoday project

Executive Summary

• Laurion Mineral Exploration Inc. has announced a new 1,700-metre diamond drill program at its 100%-owned Ishkoday project in Ontario, targeting the underexplored A-zone and McLeod zones to delineate near-surface gold and base-metal mineralization.
• The release provides context by listing significant historical gold and base-metal intercepts from previous drilling campaigns, highlighting a continuous mineralization corridor across the eastern Ishkoday project.
• Management outlined future exploration plans, including a scheduled start for the current program in late October 2025 and a significantly expanded 7,000- to 10,000-metre drill campaign planned for 2026 to advance resource definition and valuation.

Key Details

• Current Drill Program:

  • Scope: 1,700 metres of diamond drilling.
  • Location: Ishkoday project, ~220 km northeast of Thunder Bay, Ontario.
  • Target Areas: A-zone and McLeod zones (east of the main Ishkoday project).
  • Objective: Delineate and expand near-surface gold and base-metal zones (Au-Ag-Zn-Cu).
  • Start Date: Scheduled to commence in late October 2025.
  • Data Integration: Results will be incorporated into Laurion’s evolving 3-D geological model.

• Future Exploration Plans:

  • 2026 Objectives: An expanded 7,000- to 10,000-metre multiphase drill campaign.
  • 2026 Targets: Near-surface resource definition, deeper extensions beneath Sturgeon River and Brenbar mine areas, east side of Ishkoday project, and expanded structural/geochemical coverage.
  • Strategic Goal: Leverage technical data for future resource definition, development milestones, and valuation enhancement.

• Project Geology:

  • The A-zone and McLeod zones host consistent gold and zinc-rich mineralization within sheared, sulphide-rich, and quartz-veined volcanic sequences.
  • These zones, along with the Sturgeon River mine and Brenbar corridors, define a 6.0 km by 2.5 km structural trend that remains open at depth.

• Qualified Person:

  • Jean-Philippe Paiement, PGeo, MSc, consultant to Laurion.

Notable Quotes

• "This is an exciting, unanticipated addition to our 2025 exploration plans... While our principal focus remains the Sturgeon River mine and Brenbar corridors, this targeted program also reflects the growing importance of the A-zone and McLeod zone in shaping Ishkoday project's near-surface gold and base metal potential. Building upon current technical input of our evolving 3-D model, we're laying the groundwork for future resource definition and valuation growth across multiple zones." — Cynthia Le Sueur-Aquin, President and CEO.
