Doubleview extends Hat deposit 320 m eastward

Executive Summary

• Doubleview Gold Corp. announced a 320-meter eastward extension of the mineralized volume at its 100%-owned Hat polymetallic deposit in northwestern British Columbia, confirming the deposit remains open in that direction.
• The 2025 exploration program has completed over 10,200 meters of drilling in 14 holes, with mineralization intersected in every hole, validating geological continuity and supporting a significant upcoming upgrade to the mineral resource estimate (MRE).
• The company anticipates releasing the revised MRE within the next 60 days, incorporating the entire drill database to hole H101, while fresh assays are being processed and will be released as they are validated.

Key Details

• Drilling Extension: Drill holes H100 through H102 extended the deposit's footprint more than 320 meters eastward, confirming high-volume porphyry-style mineralization remains open and undefined in this direction.
• 2025 Program Progress: The company has completed more than 10,200 meters of drilling in 14 holes to date in 2025, focusing on stepping out from known resource limits to prove continuity and scale.
• Mineralization Continuity: Mineralization has been intersected in every hole completed in the 2025 program, validating the geological model and suggesting strong continuity of the mineralizing system.
• Resource Estimate Update: The entire drill database to hole H101 will be included in the revised MRE, anticipated for release in 2025. The expanded footprint with stronger assay data is expected to allow a meaningfully increased resource estimate.
• MRE Timeline: The interpreted mineralization and apparent growth in volume support a forthcoming MRE scheduled for completion within the next 60 days.
• Assay Status: Fresh assays are being received almost daily from the laboratory and will be released when processed by the company's technical team.
• Deposit Characteristics: The Hat deposit is characterized by a copper-gold-cobalt-scandium association, with elevated scandium and copper values supporting the strategy to define one of North America's largest critical-metal-bearing polymetallic deposits.
• Scandium Potential: Estimated at 300 million to 500 million tonnes at an average grade of 40 parts per million (0.004 per cent) Sc2O3.
• Visuals: A detailed drill section and plan map illustrating the newly expanded mineralized area are provided, along with a gallery of approximately 60 core photographs from recently completed, non-reported holes.

Notable Quotes

• "These new drill results represent a major step forward in understanding the true scale of the Hat deposit... The 320-metre eastward extension, combined with probable continued mineralization beyond the current limits of drilling, highlights the significant expansion potential of the system and positions Doubleview for a meaningful resource upgrade." — Farshad Shirvani, President and CEO
• "The Hat deposit, characterized by its copper-gold-cobalt-scandium association, continues to demonstrate robust continuity of mineralization and growing tonnage potential. Drilling to date indicates a broad, strongly mineralized system with elevated scandium and copper values that support the company's strategy to define one of North America's largest critical-metal-bearing polymetallic deposits." — Farshad Shirvani, President and CEO
