Vancouver, British Columbia - Newsfile Corp. - March 23, 2026 - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") provides clarification to its news release dated March 2, 2026, announcing the Preliminary Economic Assessment ("PEA") for the Company's 100% owned Hat Project in northwestern British Columbia. Following publication of the March 2, 2026 news release, Mineit Consulting Inc., the independent engineering firm responsible for the PEA, completed a further review of the application of certain processing cost assumptions relating to the scandium recovery circuit in Scenario B. As a result of this review, the after-tax NPV(5%) for Scenario B at consensus metal prices has been updated to C$7.27 billion from C$6.94 billion and IRR of 19%. The update also results in an increase in Scenario B after-tax NPV(5%) at spot metal prices to C$14.85 billion from C$14.52 billion and IRR of 32%. The updated Scenario B results further demonstrate the economic contribution of the scandium recovery circuit and increase the difference in after-tax NPV between the base case (Scenario A2) and Scenario B to C$547 million. The cobalt grade reported in Table 1 of the Company's March 2, 2026 news release was inadvertently shown as 0.78 g/t Co. The correct value is 78 g/t Co, consistent with Table 5 of the release. This discrepancy was limited to the summary table presentation and does not affect the PEA results or conclusions. These clarifications do not change the overall conclusions of the PEA and further highlight the strong economics of the Hat Project, including the potential value contribution from scandium recovery. Corrected highlights of the PEA reflecting the updated Scenario B economics are presented below. 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), 13.53 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....
