Doubleview Gold Corp Extends Mineralization East of 2024 Conceptual Pit and Identifies Deeper Porphyry Indicators at Hat Project by Drilling 992m of 0.29% CuEq in Hole H101

The most recent news release from December 16, 2025, reports positive assay results from drill holes H100 and H101 at Doubleview Gold Corp.'s (DBG) Hat Polymetallic Deposit in British Columbia. Key highlights include: - Drill Hole H101: Intersected 992.4 meters grading 0.29% Copper Equivalent (CuEq), notably with a higher gold-to-copper ratio. This hole extended mineralization east of the 2024 conceptual pit and indicated deeper porphyry indicators. - Drill Hole H100: Intersected 497.0 meters grading 0.27% CuEq, also extending mineralization eastward beyond the 2024 conceptual pit and exhibiting elevated cobalt values. - The company states these results represent a significant step in understanding the Hat system, confirming mineralization continuity at depth and eastward. - The findings reinforce the interpretation of Hat as a large, vertically extensive porphyry system, with the deepest parts remaining untested. - The mineralization envelope has been expanded, and the results are expected to justify continued exploration for depth and lateral extensions.

This follows closely on the December 8, 2025, announcement of the successful completion of the 2025 drilling season, which was the largest to date with 13,290 meters drilled across 19 holes. All holes intersected mineralization, and a new deep mineralized horizon was discovered beneath the 2024 conceptual pit shell. Assays for holes H100-H108 were pending at that time, making the current news the release of results for two of those holes.

Earlier news in December 2025 highlighted significant assay results from holes H097, H098, and H099, expanding the mineralization envelope both vertically (200m down-dip) and laterally (100m). Notably, H099 returned 438m of 0.40% CuEq, including a high-grade section of 52m of 1.02% CuEq.

The company has also emphasized the cobalt and scandium potential of the Hat Project. A December 2, 2025, release provided a cobalt resource summary (Indicated: 28 Mlb, Inferred: 91 Mlb Co), positioning it as a meaningful component of the project's critical minerals profile. A major breakthrough in scandium recovery from copper porphyry tailings was announced on November 25, 2025, reporting 82% primary extraction and 88% overall recovery to high-purity Sc2O3, which the CEO termed a "game-changer."

Financially, Doubleview Gold successfully closed a non-brokered private placement for gross proceeds of $7,181,400 in November 2025, securing capital for its exploration program and general working capital.

The news from December 16, 2025, reporting extensive and consistent copper equivalent (CuEq) mineralization in drill holes H100 and H101, is materially positive for Doubleview Gold Corp. 1. Resource Expansion: The intercepts, particularly the 992.4-meter length in H101, demonstrate significant mineralization continuity at depth and to the east. This directly supports the company's objective of expanding the Hat Deposit beyond the existing 2024 conceptual pit. This expansion is crucial for increasing the overall resource base, which is a primary value driver for exploration companies. 2. Validation of Geological Model: The results validate the company's interpretation of Hat as a large, vertically extensive porphyry system. This improved geological understanding is essential for optimizing future exploration and development plans. 3. Polymetallic Value Enhancement: The detection of elevated cobalt in H100 and higher gold-to-copper ratios in H101 provides valuable insights into the internal zonation of the system, reinforcing the polymetallic nature of the deposit beyond just copper and gold. This aligns with the company's strategy to highlight critical minerals like cobalt and scandium. 4. Foundation for Future Studies: These drill results will be incorporated into the upcoming updated Mineral Resource Estimate (MRE-2) and Preliminary Economic Assessment (PEA). Strong drill results directly contribute to an enhanced resource base and potentially improved project economics in the PEA. This is a critical de-risking step. 5. Consistency with Previous Expectations: The results are consistent with, and even exceed, previous expectations set by the company (e.g., the 2025-12-08 news of 100% drilling success and discovery of a new deep horizon, and earlier positive drill results from H093-H099). The company had explicitly stated that drilling was aimed at expanding the resource and better defining the system.

The significance of these deep and extensive intercepts in a porphyry environment suggests a robust and growing mineralized system. Combined with the recent metallurgical breakthrough for scandium recovery, these developments collectively enhance the Hat Project's profile as a significant source of critical metals in a Tier-1 jurisdiction. The market's reaction to such news is typically positive, as it de-risks the project and provides a strong foundation for future economic studies.

Doubleview Gold Corp. (TSXV: DBG, OTCQB: DBLVF, FSE: 1D4) is a Canadian mineral exploration company primarily focused on the Hat Polymetallic Deposit in Northwestern British Columbia. The Hat Project is characterized as a large, vertically extensive porphyry deposit containing significant resources of copper, gold, cobalt, silver, and the potential for scandium. The company has been actively conducting extensive drilling campaigns to expand and upgrade its mineral resources. The project is strategically located in a Tier-1 mining jurisdiction.

In addition to the Hat Project, Doubleview Gold also holds the Red Spring Project in central British Columbia, an exploration target for copper, silver, and zinc. The company initiated an advanced exploration program at Red Spring in July 2025, which includes a 3-D IP survey, aiming to define targets for future drilling.

The company's strategy revolves around defining and developing polymetallic deposits rich in critical and strategic metals, aligning with the growing global demand for materials essential for the electrification economy. Key ongoing initiatives include an updated Mineral Resource Estimate (MRE-2), a Preliminary Economic Assessment (PEA), and metallurgical studies, particularly for scandium recovery.
