Doubleview Gold Corp. Announces Filing of Preliminary Economic

Assessment Technical Report for the Hat Project

Vancouver, British Columbia - 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 prices 2. 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 (Natu ral 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.
