Doubleview Gold Corp. Announces Filing of Preliminary Economic Assessment Technical Report for the Hat Project

Vancouver, British Columbia - Newsfile Corp. - April 14, 2026 - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to announce that it has filed the independent National Instrument 43-101 Technical Report entitled "Preliminary Economic Assessment of the Hat Polymetallic Project, British Columbia, Canada" (the "Technical Report") on SEDAR+ at www.sedarplus.ca and it can also be viewed on the Company's website at www.doubleview.ca. The Technical Report supports the positive Preliminary Economic Assessment ("PEA") results for the Company's 100%-owned Hat polymetallic porphyry project ("Hat" or the "Project"), located in northwestern British Columbia, as announced on March 2, 2026 and clarified on March 23, 2026.

The PEA demonstrates robust project economics for the Hat Project, including:

NPV:

• After-tax NPV(5%) of C$6.73 billion and IRR of 23% at Consensus Metal Prices
• After-tax NPV(5%) of C$13.53 billion and IRR of 39% at Spot Metal Prices

NPV Including scandium and the associated processing circuit:

• After-tax NPV(5%) of C$7.27 billion and IRR of 19% at Consensus Metal Prices
• After-tax NPV(5%) of C$14.85 billion and IRR of 32% at Spot Metal Prices

Three processing scenarios were evaluated-Scenario A1 (A1) a Cu-Au-Ag-Co flotation base case using current testwork recoveries¹, Scenario A2 (A2), the same base case using expected recoveries¹, and Scenario B (B), a Cu-Au-Ag-Co flowsheet with an added hydrometallurgical circuit and scandium recovery circuit, with results indicating the Project is financially attractive even without the scandium component.

Highlights:

• Robust Project Economics: The PEA demonstrates a high-margin operation with an After-Tax NPV(5%) of C$4.96 billion (A1), C$6.73 billion (A2), or C$7.27 billion (B), and an IRR of 19% (A1), 23% (A2), or 19% (B) at analyst consensus metal prices². Using a spot-price scenario³, the Project delivers a compelling after-tax NPV(5%) of C$11.05 billion (A1), C13.53 billion (A2), or C$14.85 billion (B) and an IRR of 34% (A1), 39% (A2), or 32% (B).
  
• Sensitivity Highlight: Project economics show the greatest leverage to overall metal prices, with NPV (5%) ranging from C$3.2 billion to C$10.2 billion (IRR: 14%-32%) at ±20% on all metals; even under additional +20% CAPEX and +20% OPEX sensitivities, applied on top of a 25% contingency already embedded in the base case, all scenarios deliver IRRs of 16% or better, and Scenario B provides additional scandium oxide upside with NPV(5%) of C$6.5 billion-C$8.1 billion (IRR: 18%-20%) at ±40% metal price.
  
• Scale and Longevity: The mine plan supports a multi-decade life of 25 years at a 120,000 tonnes-per-day processing rate, underpinned by a resource base of 609 Mt at 0.43% CuEq⁴ in the Measured and Indicated categories and 503 Mt at 0.41% CuEq⁴ in the Inferred category.
  
• High-Output Production Profile B: Envisioned as a conventional large-scale open-pit operation, the Project is expected to produce an average of over 74 kt of copper, 254 koz of gold, 376 koz of silver and 2.7 kt of cobalt annually during the first 10 years, with life-of-mine (LOM) average production of 67.6 kt Cu, 217 koz Au, 348 koz Ag, 2.5 kt Co, and 128 tonnes of scandium oxide per year. (NOTE: based on publicly reported 2024 North American cobalt mine production of approximately 3,800-4,000 tonnes (Natural Resources Canada; U.S. Geological Survey), the projected cobalt output is estimated to represent approximately 69% of current regional mined supply).
  
• Strategic Importance for Critical Minerals: The Project is positioned as a primary North American source of copper, scandium, and cobalt. With approximately 2.42 billion pounds of copper, 80 million pounds of cobalt and 2,415 tonnes of scandium oxide contained⁵ in the Measured and Indicated categories, the Project represents an important discovery of critical minerals.
  
• Stable, Supportive Jurisdiction: Located in a premier mining district in British Columbia, the Project benefits from a stable regulatory environment. The Company is committed to engaging with local First Nations in a respectful manner and to working toward positive and constructive relationships as the Project advances.
  
• Catalyst for Development: The PEA serves as the technical foundation for an immediate transition into a Pre-Feasibility Study (PFS), providing a clear roadmap for early works and permitting activities in 2026 and 2027.
  

Farshad Shirvani, President and CEO of Doubleview Gold Corp., commented: "The filing of the full PEA Technical Report solidifies the robust economics outlined in March. With an after-tax NPV(5%) reaching up to C$7.27 billion at consensus prices and up to C$14.85 billion at spot prices, we believe the Hat Project is emerging as a Tier 1 asset. It is a large-scale, long-life polymetallic opportunity in a premier jurisdiction with strong exposure to critical metals including copper, scandium and cobalt. We look forward to advancing this strategic asset toward pre-feasibility while continuing to unlock value from its copper, gold, scandium and cobalt potential."

The Company cautions that the PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
