Vancouver, British Columbia - Newsfile Corp. - December 4, 2025 - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to announce assay results from drill holes H097, H098, and H099 from its 2025 drill program at the Hat Polymetallic Deposit in northwestern British Columbia. Drill holes H097, H098 and H099 were collared from the same platform as drill holes H093-H096 and were drilled into previously untested potential extensions of the deposit and have successfully expanded the mineralized footprint approximately 100m laterally and 200 meters vertically and strengthened confidence in continuity in part of the Lisle Zone. Highlights

• H099 returned 438.0 metres of 0.40% CuEq, including 52.0 metres of 1.02% CuEq, representing one of the strongest continuous mineralized intervals drilled at the Hat deposit to date.
• H097 and H098 confirm mineralization in previously undrilled sections and extend data approximately 200-300 metres down-dip and up to 100 metres laterally and fill important gaps in the geological exploration model. Drill holes H097, H098 and H099 when integrated into the database potentially will extend the 2024 conceptual open-pit shell by ~200 metres down-dip and up to 100 metres laterally, and demonstrate strong expansion potential that may be realized in the revised version of the 2024 Mineral Resource Estimate (MRE-2) and the Preliminary Economic Assessment (PEA).
• Drill hole analyses reported in this News Release show continuity of copper-gold-cobalt-scandium domains [scandium is an emerging critical metal and an important component of the Hat deposit], across broad intervals of the system.
• These drill holes support the Company's objective to complete an up-dated Mineral Resource Estimate (MRE-2) and a Preliminary Economic Assessment (PEA) and improve confidence in the exploration model all of which will be incorporated in the current and future engineering studies *Copper Equivalent (CuEq) values exclude scandium (Sc2O3).*
