Doubleview Provides Hat Project Development Update as Ongoing Drilling Supports Next Mineral Resource Estimate and Pre-Feasibility Advancement

Doubleview Gold Corp. (TSXV: DBG,OTC:DBLVF) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to provide an update on ongoing technical and development work at its 100%-owned Hat Project in northwestern British Columbia. Following the Company's June 9, 2026 announcement reporting assay results from drill holes H102 to H108, which extended Hat mineralization approximately 150 metres east beyond the known resource envelope, Doubleview is advancing a work program designed to support continued resource growth, technical de-risking and the next phase of project evaluation.

The Company's current drilling program remains focused on increasing the size and confidence of the Hat deposit in support of an updated Mineral Resource Estimate ("MRE") currently targeted for early 2027, while also generating information relevant to ongoing Pre-Feasibility Study ("PFS") planning.

Highlights

• Ongoing drilling is focused on expanding the Hat deposit and supporting the next updated MRE targeted for early 2027.
• The current drill plan is under review and is being optimized to improve efficiency and better align with the Company's MRE and PFS objectives.
• Doubleview is nearing a final decision on the selection of a metallurgical laboratory following an extensive international review process led by the Company's metallurgical team.
• Baseline environmental studies have been initiated, and field equipment has been shipped for installation in the coming weeks.
• The Company is fully funded to carry out its currently planned work programs.

Farshad Shirvani, President and CEO of Doubleview Gold Corp., commented:

"The results we announced in June marked an important step forward for the Hat Project, and the ongoing drilling program is designed to build on that momentum. With mineralization now extended beyond the previously defined resource envelope, we are increasingly confident that Hat is moving toward the next stage of development. Our immediate objective is to support an updated Mineral Resource Estimate targeted for early 2027 while advancing the technical work necessary for pre-feasibility planning."

"At the same time, we are progressing the parallel workstreams required to move a project of this scale forward responsibly and efficiently. These include optimizing the current drill plan, completing metallurgical program planning, initiating baseline environmental studies and maintaining the financial capacity to execute on our objectives."

"We also believe the strategic relevance of Hat continues to strengthen. In a market where secure North American sources of critical minerals are becoming increasingly important, Hat's exposure to copper, cobalt and scandium in a Canadian jurisdiction positions the Project as a potentially important long-term contributor to domestic and allied supply chains."

Doubleview believes that recent developments in cobalt markets and North American critical minerals policy continue to underscore the long-term strategic value of polymetallic projects located in stable jurisdictions. While Hat remains an exploration and development-stage project, management believes its combination of copper, cobalt, scandium, gold and silver provides important exposure to metals that are increasingly relevant to electrification, industrial resilience and supply chain security.

The Company will provide further updates as technical planning advances and key milestones are reached.
