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 — (December 8, 2025) — Doubleview Gold Corp. (“Doubleview” or the “Company”)

(TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) 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.
