Boreal Gold to begin North Star exploration this fall

Executive Summary

• Boreal Gold Inc. reports significant gold assay results from the Fay Property, including a high-grade sample of 14.33 g/t gold from 2021 and recent 2025 samples showing 4.03 g/t gold with associated silver, copper, and zinc.
• The company identified a large, unusual quartz feldspar porphyry system at the Fay Property with a strike length of 600m, hosting gold-bearing sheared veins and a new showing assaying 4.07 g/t gold.
• Boreal Gold plans to commence exploration on the North Star-Gold Rock property this fall, leveraging over $9 million in historical work and infrastructure, with plans for infill and downplunge drilling to define a resource estimate.

Key Details

• Fay Property Assay Results:
  • Sample 27309 (collected 2021): 14.33 g/t gold and 65.8 g/t silver.
  • Sample 27475 (collected 2025): 4.03 g/t gold, 122 g/t silver, 0.13% copper, and 0.25% zinc; anomalous arsenic and lead also detected.
  • Sample 27473: 410 ppb gold from a rediscovered 2m x 20m trench in a gossanous, altered, and sheared quartz feldspar porphyry zone.
  • New Showing: A rusty quartz vein with 1-2% vuggy pyrite hosted in gabbro, 58m north of the porphyry, assayed 4.07 g/t gold from a 1m x 2m trench.
• Geological Findings at Fay Property:
  • Discovery of a quartz feldspar porphyry at least 15m wide with 1-5% pyrite, unusual in width and continuity, covering the full strike length of the mapped grid.
  • The porphyry has a present strike length of 600m and is open in both directions.
  • Gold-bearing porphyry appears hosted in gabbro with flanking sheared veins containing gold.
  • Plans to follow up with additional prospecting and mapping to the east to discover the extent of the porphyry and its gold-bearing system.
• Koscielny Lake Targets:
  • Plans to investigate and sample sites south of the Puffy Lake gold mine reported to contain significant gold, with historical values up to 11.81 g/t Au over 1m.
• North Star-Gold Rock Property Exploration Plans:
  • Property optioned from Voyageur Mineral Explorers Corp. (April 17, 2025).
  • Historical work since 2003 includes $9 million spent, 278 total drill holes (135 at North Star, 143 at Gold Rock), ramp access, underground development, and extensive surface sampling.
  • Historical metallurgical testing (Lakefield) showed 85% gold recovery by gravity alone.
  • Infrastructure includes a 2km all-weather road, camp site, storage areas, mill foundation, and valid environmental permits.
  • Planned Activities:
    • Line cutting and refurbishing old grids (Line 46 N to 59 N).
    • Geological remapping and detailed sampling, especially between North Star and Gold Rock deposits.
    • Selective infill and downplunge drilling on the Gold Rock vein.
    • Objective: Complete a NI 43-101 compliant technical report and resource estimate to warrant a prefeasibility study.
    • Drilling plan for Gold Rock outlined; targets on North Star and intermediate areas contingent on fall results.

Notable Quotes

• "The 50 to 75 m wide porphyry is unusual in width and continuity covering the full strike length of the grid mapped to date. Unlike other quartz feldspar porphyries in the area, it is much larger and altered and contains significant gold, and likely earlier than other porphyries in its intrusive history."
• "With gold presently over $3,600 (U.S.) and over $5,000 (Canadian) per ounce, Boreal Gold will continue its focus on gold by also exploring the North Star property this fall..."
