Doubleview Gold Corp Announces 320-Meter Eastward Extension at the Hat Polymetallic Deposit, Expanding Mineralized Volume and Remaining Open

Press Release

Oct 23, 2025

Doubleview Gold Corp (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) (“Doubleview” or the “Company”) is pleased to report that ongoing drilling at its 100%-owned Hat Polymetallic Deposit in northwestern British Columbia has extended the mineralized system approximately 320 meters eastward, further confirming that the deposit remains open in multiple directions. The 2025 exploration program continues to expand the mineralized envelope, with results expected to contribute significantly to the upcoming Mineral Resource Estimate (MRE).

2025 Exploration Program Highlights

To date in 2025 drill program, the Company has completed more than 10,200 meters of drilling in 14 holes. The focus has been to step out from the known resource limits to prove continuity and scale. Key results from this phase of the program include:

• Significant Extension: Drill holes H100 through H102 have successfully extended the deposit’s footprint more than 320 meters eastward, confirming that the high-volume porphyry-style mineralization remains open and undefined in this direction.
• Consistent Mineralization: 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 Inclusion: 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 and strong visuals as illustrated in the accompanying core photo gallery, is expected to allow a meaningfully increased resource estimate.

The 2025 drilling program comprises more than 10,200 meters in 14 holes and the observed mineralization has been extended more than 320 metres to the east. The interpreted mineralization and the apparent growth in volume provide strong support for the forthcoming MRE that is scheduled for completion within the next 60 days.  Fresh assays are being received almost daily from the laboratory and will be released when processed by our technical team.

“These new drill results represent a major step forward in understanding the true scale of the Hat Deposit,” said Farshad Shirvani, President and CEO of Doubleview Gold Corp. “The 320-meter 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.

“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.  Important amounts of gold, cobalt and silver are present.

A detailed drill section and plan map illustrating the newly expanded mineralized area are provided below. In addition, a gallery of approximately 60 core photographs from recently completed, non-reported holes accompanies this release. The Company anticipates announcing assay results from these holes as soon as analytical data are received, validated, and interpreted”.

IMPORTANT VISUAL DISCLOSURE: The visual observations of mineralization, including core photos, are preliminary in nature and are not a substitute for assay results. The Company cautions that visual estimates of mineralization are not indicative of the actual grade or economic viability of the resource. Assay results are pending for the core included in the photos and will be published once received, verified, and analyzed under the Company’s strict Quality Assurance/Quality Control (QA/QC) program.
