Doubleview completes 2025 drilling at Hat project

Executive Summary

• Doubleview Gold Corp. completed its largest-ever drilling season at the Hat polymetallic project in northwestern British Columbia, drilling 13,290 meters across 19 holes with a 100% success rate.
• The campaign identified a new deep mineralized horizon beneath the 2024 conceptual pit shell, confirming significant down-dip continuity and expansion potential, while validating the geological and resource models.
• Pending assay results from holes H100-H108 will be incorporated into the upcoming Mineral Resource Estimate (MRE-2) and Preliminary Economic Assessment (PEA).

Key Details

• Drilling Volume: 13,290 meters of diamond drill core drilled across 19 holes, averaging 699.5 meters per hole.
• Success Rate: 100% of drill holes intersected mineralization.
• Geological Findings:
  • Identification of a newly recognized mineralized horizon beneath and adjacent to the 2024 conceptual open-pit shell.
  • Mineralization remains open to depth and laterally in multiple directions.
  • Existing data gaps were closed, and mineralization domains were better defined.
• Specific Hole Highlights:
  • H097, H098, H099: Extended mineralization by 200 to 300 meters down-dip and up to 100 meters laterally, significantly improving the block model.
  • H099: Returned 438 meters of 0.40% CuEq (copper equivalent), including 52 meters of 1.02% CuEq, described as one of the strongest continuous intervals drilled at the Hat to date.
• Pending Assays: Assays for holes H100 through H108 (9 holes) are pending and will be released once received, reviewed, and interpreted in accordance with National Instrument 43-101.
• Future Work:
  • Pending assays will inform updates to the Mineral Resource Estimate (MRE-2) and the Preliminary Economic Assessment (PEA).
  • The company notes that due to timing issues, it may not be able to include all assay data in those technical reports.
• Critical Metals: The 2025 work advances the understanding of copper-gold-cobalt-scandium mineral domains, building on recently announced potential scandium recovery achievements.
• Scandium Potential: Estimated at 300 million to 500 million tonnes at an average grade of 40 parts per million (0.004%) Sc2O3.

Notable Quotes

• Farshad Shirvani, President and CEO: "This has been a transformational year for Doubleview and the Hat project. Our 2025 drill campaign successfully demonstrated the strength of our geological model, filled key data gaps and uncovered an entirely new mineralized horizon beneath the 2024 conceptual pit shell. Every drill hole intersected mineralization, which is a testament to the quality and strength of our technical team, along with the robustness of the system."
