Resource estimate highlights:

• Measured Mineral Resources of 272 million tonnes (Mt), Indicated Mineral Resources of 337 Mt, and Inferred Mineral Resources of 503 Mt at a 0.2% copper equivalent (CuEq) cut-off grade, or
• 272 Mt of Measured Mineral Resources, expressed in contained metal, total 2.61 billion pounds (Blb) of copper equivalent (CuEq) at 0.44% CuEq, including 1.11 Blb of copper, 35.6 million pounds (Mlb) of cobalt, 1.41 million ounces (Moz) of gold, and 2.17 Moz of silver. (Table 1)
• 337 Mt of Indicated Mineral Resources, expressed in contained metal, total 3.21 Blb of 0.43% CuEq, including 1.31 Blb of copper, 44.5 Mlb of cobalt, 1.81 Moz of gold, and 2.88 Moz of silver. (Table 1)
• 509 Mt of Inferred Mineral Resources, expressed in contained metal, total 4.57 Blb of 0.41% CuEq, including 1.72 Blb of copper, 66.2 Mlb of cobalt, 2.77 Moz of gold, and 4.19 Moz of silver. (Table 1)
• Scandium Resource: The deposit hosts 609 Mt in the Measured and Indicated categories (containing approximately 17,510 tonnes of scandium) and 504 Mt in the Inferred category (containing approximately 14,465 tonnes of scandium). Scandium has been incorporated into the Mineral Resource Estimate and under current processing constraints, is limited to 12.5% of tailings using internally generated acid. The scandium resource is estimated at 76 Mt Measured and Indicated at 28.8 g/t Sc (containing 2,189 tonnes of scandium) and 63 Mt Inferred at 28.7 g/t Sc (containing 1,808 tonnes of scandium).

Vancouver, British Columbia - (Newsfile Corp. - February 25, 2026) - Doubleview Gold Corp (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to announce the update of the Mineral Resource estimate (MRE) of its 100%-owned polymetallic Hat porphyry project (Hat), in northwestern British Columbia. With major content of copper, gold, cobalt and silver, as well as scandium, Hat becomes an important source of critical minerals. Farshad Shirvani, president and CEO of Doubleview Gold Corp commented, "Year by year, the size of the deposit was increased by very targeted drilling, bringing it to a footprint of about 1.6 km by 1.6 km. I appreciate my technical and management team in this endeavour. We've discovered numerous additional elements within the Hat deposit that will soon be unveiled, each further showcasing the deposit's uniqueness and enhancing the resource."
