Doubleview Gold Corp. Announces Successful Completion of 2025 Drilling Season at the Hat Project, the Largest Drill Season yet with 13,290m Diamond Drill Core

Vancouver, British Columbia - Newsfile Corp. - December 8, 2025 - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to announce the completion of its 2025 drilling season at the Hat Polymetallic Project in northwestern British Columbia. This year's program marks the largest drilling campaign in the Hat Project's history, with 13,290 metres drilled across 19 drill holes, achieving a 100% success rate with every drill hole intersecting mineralization, while confirming the deposit remains open to depth and laterally. The 2025 campaign delivered major advancements in our understanding of the geology and dimensions of the Hat deposit, including the identification of a newly recognized mineralized horizon located beneath and adjacent the 2024 conceptual open-pit shell. Importantly, mineralization domains were better defined, existing data gaps were closed, and the Company's evolving geological and resource models were validated (see Figures 1-4, also available on the Company's website at www.doubleview.ca). Assays from holes H100 through H108 remain pending and will be released once received, reviewed, and interpreted in accordance with NI 43-101. Highlights of the 2025 Drill Season

• 13,290 metres drilled in 19 holes, averaging 699.5 metres per hole — the largest and most efficient and technically productive program ever.
• A newly discovered deep mineralized horizon beneath the 2024 conceptual pit outline confirms significant down-dip continuity and expansion potential as mineralization remains open at depth and laterally in multiple directions.
• Every drill hole intercepted mineralization, demonstrating the strength and continuity of the porphyry system.
• H097, H098, and H099, previously disclosed, extended mineralization by 200-300 metres down-dip and up to 100 metres laterally, significantly improving the block model and geological interpretation.
• H099 returned 438 m of 0.40% CuEq, including 52 m of 1.02% CuEq, another one of the strongest continuous intervals drilled at the Hat to date.
• Newly completed holes H100-H108 were strategically positioned to evaluate depth extensions, lateral continuities, and untested model gaps. Core samples from these drill holes are being processed at the independent assay lab.
• Pending assays for nine remaining holes will inform updates to the Mineral Resource Estimate (MRE-2) and the ongoing Preliminary Economic Assessment (PEA). Note: Due to timing issues, we may not be able to include all assay data in those technical reports.
• 2025 work further advances Doubleview's understanding of copper-gold-cobalt-scandium mineral domains. The recently-announced potential scandium recovery achievements are a major milestone for the Hat's critical-metals profile.

Farshad Shirvani, President & CEO, commented:"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.The discovery potential at Hat continues to expand, with the deposit remaining open both laterally and at depth. Combined with last year's exceptional drill results, our scandium recovery breakthrough, and the ongoing work toward the updated Resource Estimate and PEA, we are entering the next phase of project development with a high degree of confidence and momentum. I extend my thanks to our technical team, contractors, and shareholders for enabling the most successful drilling season in our Company's history." The Company is now focused on completing the assay review and disclosure for drill holes H100 through H108, which represent the final nine holes of the 2025 program. Assay results, when received, verified, and interpreted in accordance with NI 43-101 standards, will be announced and incorporated into the geological and resource models. In parallel, the Company continues to advance its Preliminary Economic Assessment (PEA), which is currently undergoing both internal modelling and external third-party review. The integration of the full 2025 drill dataset, including pending assays, is expected to materially enhance the confidence and robustness of the forthcoming PEA, supporting a comprehensive evaluation of the Hat Project's economic potential and paths to development.
