Vancouver, British Columbia - Newsfile Corp. - December 16, 2025 - Doubleview Gold Corp. (TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) ("Doubleview" or the "Company") is pleased to report assay results from drill holes H100 and H101, completed as part of the 2025 drill program at its 100%-owned Hat Polymetallic Deposit in northwestern British Columbia. Drill holes H100 and H101 were designed to test eastern extensions of mineralization beyond the 2024 conceptual pit shell, while also evaluating depth continuity and metal zonation within the Hat porphyry system. Results from both drill holes confirm broad, continuous copper-gold-cobalt-scandium mineralization and, when integrated with drill holes announced earlier in 2025, define an expanded mineralization envelope at the Hat Deposit. Assay results from drill holes H102 to H108 will be released when received from the Lab and reviewed and confirmed by our technical team. Key Highlights

• Mineralization extended eastward beyond the 2024 conceptual pit outline, supported by long, continuous intercepts in both H100 and H101.
• H100 intersected 497.0 m of mineralization (129.0-626.0 m) averaging 0.27% CuEq (excluding Sc₂O₃), confirming continuity into previously under-tested areas east of the 2024 conceptual pit.
• Elevated cobalt values at depth in H100 may be indicative of proximity to deeper portions of the porphyry system based on observed metal associations at Hat.
• H101 returned 992.4 m of continuous mineralization, with multiple higher-grade intervals and a higher gold-to-copper ratio relative to the established average of the Hat deposit.
• Deeper part of the Hat porphyry system remain untested by drilling,
• Drill holes H100 and H101 at the bottom are more than 500m apart.

Drill Hole H100

• 497.0 m (129.0-626.0 m) averaging 0.27% CuEq, including:
  • 239.8 m at 0.30% CuEq
  • 141.0 m at 0.31% CuEq
  • 106.2 m at 0.35% CuEq
  • 73.0 m at 0.44% CuEq

Drill hole H100 confirms that mineralization extends eastward beyond the 2024 conceptual pit boundary and remains continuous over substantial thicknesses. The presence of elevated cobalt values within deeper intervals is interpreted by the Company as a potential vector toward deeper parts of the porphyry system. While the significance of this association continues to be evaluated, cobalt enrichment has consistently occurred alongside stronger copper-gold mineralization in several areas of the Hat deposit. Drill Hole H101

• 992.4 m (7.5-999.9 m) averaging 0.29% CuEq, including:
  • 618.0 m at 0.37% CuEq
  • 153.0 m at 0.52% CuEq
  • 91.0 m at 0.72% CuEq
  • 32.0 m at 1.26% CuEq
  • 11.2 m at 2.80% CuEq

Drill hole H101 is notable for its higher gold-to-copper ratio compared to the broader Hat deposit average. Such metal ratios are commonly observed within zoned porphyry systems and may reflect variations in metal distribution at different structural or vertical levels. Together with the observed continuity of mineralization from near surface to the end of the drill hole, adds an important new constraint to the evolving geological interpretation of the Hat system.
